You should do an update, Zope 2.7 is 2.7.3 in current Debian testing
and unstable and woody has no zope27 (for woody I would suggest to
compile python2.3 and zope27 from source)

This is http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=288350

If you have the same problem with a 2.7.3 Zope2.7 I'd suggest to send
a report to this bug.

Is there an automated tool for Zope that will run repozo on a set
schedule to pack a Zeo/Zope Data.fs so that you don't have to manually
call the script from the command line?

If Zope is not restarted python2.3 will consume all physical memory and
then start using swap.  The server slows to a crawl and Zope will
eventually stop serving pages.

I've been watching the debug page in the control panel and the refcounts
fluctuate up and down by small amounts but the trend is always up.  They
never seem to level off, they always climb.

Is this typical or does this suggest a problem?

I wrote a new test script in
/usr/lib/Zope-2.7/lib/python/Products/Transience/tests that creates
sessions with large arrays of random data.  Running this test did not
seem to cause any leaks.  However, if I uses sessions in Zope, Zope
seems to leak.  The larger my session data the faster it leaks.

Here is the output from the debug control panel.

# Zope version: (Zope 2.7.3-0, python 2.3.4, linux2)

Probably a pretty simple question.  The following gives me an 
&amp;nbsp; in my output which is probably what I am telling it to do.  
I want a simple &nbsp; so that my empty td's have contents when there 
is nothing in them and my tables will behave in IE.

<td tal:define="option_description option/description">	
	<span tal:condition="python:option_description == ''" 
tal:content="string: &nbsp;" tal:omit-tag="">
		&nbsp;
	</span>
	<span tal:condition="python:option_description != ''" 
tal:content="option_description" tal:omit-tag="">
		Description goes here.
	</span>
</td>

Can someone advise me what I should be substituting in the string to 
provide the desired output.  Also, is there a better way of handling 
empty table cells than a separate set of condition statements for each 
td that may be empty?

Regards,
David

You can just change 'string: &nbsp;' to 'structure string: &nbsp;', so that it 
is not html quoted.  I would also use 'tal:replace' in place of 'tal:content' 
and 'tal:omit-tag', and perhaps simplify the conditions to 
'tal:condition="option_description"' and 'tal:condition="not: 
option_description"' (unless you explicitly want to show non-string false 
values like 0, False, [], {}, (), None as strings, which you may).

(snip)

WHy not leave out tal:replace or tal:content entirely?

 <span tal:condition="python:option_description == ''"
       tal:omit-tag="">
   &nbsp;
 </span>

That has the effect I think you're after.

Hi All,

I've a strange problem with the Browser Id en Internet Explorer 6 
clients. Sometimes a client keeps getting a new browser id and as a 
result the sessioning doesn't work. This is resolved bij removing the 
cookies of the client, after that the client is keeping the same browser 
id again, but after a while the same problem can occur again.

Has anyone had the same problem or anyone to know a solution to this 
problem?

Indeed. Use the "structure" keyword to tell "tal:content/replace"
not to perform HTML quoting...

Read the Zope Book (2.6/2.7 edition, online) in case you are
unfamiliar with "structure"...

Flush the ZODB caches ("Control_Panel --> Database Management -->
<database> --> "Flush cache" --> "minimize").

After that, all reference counts should be small.
If not, you have a leak. The classes with high reference counts
probably will give you glues which objects are leaking...

It is strange that you have that many session objects...

What is your session limit? What is your session exiration time?

OK so the numbers are small.  This means there is no leak right?  It may
not be leaking, but python still consumes all available memory and dies
unless I restart Zope every few days. ;-)

Hi all

I use Plone 2 with Enterprise Enhancements from CA in a Win XP sp2. It works
fine (even i dont know how :) Now i tried to install Eric Barroccas
MSWordDocument 0.8. I untarred the folder to ..\Plone\Data\Products\

Die Installation should work like this:

-------------
MS Windows systems

   1. Install Python1.5 and Win32 Extensions build 136 (win32all-136.exe).
   2. Extract MSWord Document Product archive (MSWordDocument.tar.gz) in
your Zope Products directory.
   3. Generate Python/COM bindings:
          * Find and launch "makepy.py"
          * Select "Microsoft Word x Object Library"
          * Valid
   4. Make sure Zope is allowed to write in C:\WINDOWS\TEMP
   5. Start Zope with 'C:\PROGRA~1\PYTHON\PYTHON.EXE C:\ZOPE_ROOT\Z2.PY -D'

Note: Win32 extensions are available from
http://downloads.activestate.com/ActivePython/windows/win32all/win32all-136.exe

-------------

1. First of all there isnt a Win32 extension on activestates Page anymore.
2. Whats the point "valid" meaning?
3. I cant find a script named Z2.PY

You could invoke python the same way 'debug' command of zopectl does, e.g.:

   $ python -c "import Zope
                Zope.configure( '/path/to/zope.conf' )
                app = Zope.app()" -i

from within a shell / batch file with the appropriate environment set up 
(i.e., containing PYTHONPATH, SOFTWARE_HOME, and INSTANCE_HOME).

that's because you're looking for the "pdf" attribute of the "blah"
object.

getattr(context, "blah.pdf") should get you the file object...

Put the definitions you find in "bin/runzope.bat" into your
environment.

Run

	python -i -c "from Zope import configure; configure('path to your config file'); import Zope; app=Zope.app()"


Of course, you can put this into a batch file.

Right -- at least not the usually leaks.

The reference count list shows you only reference counts for
instances (and not elementary types). You might build leaking cycles
consisting only of elementary types -- but this is quite
unlikely.

Also, Python never releases integer objects it has constructed.
Thus, once you iterated from 0 to 4 G, you have several GB
of integer objects -- but it is unlikely that you do this...

You did this flushing and looking at the reference counts in
a process that already had run for several days (and therefore was quite
huge)?


Do you use C extensions that create non-Python objects (and
therefore do not have reference counts and show up in the list)?
Maybe, such a C extension is leaking.


There are tools to analyse memory leaks (and other memory related problems).
Once, I have use the (commercial and expensive!) "purify".
Andreas (Jung) told me that there are free open source tools
for this purpose around. Unfortunately, I forgot the details
(I only create standard leaks :-)

Are your sessions huge?
Usually, they are stored as pickles in RAM.
If they were huge, some thousands of sessions might
consume a considerable amount of RAM. You would not see
them in the reference counts because Pickles are strings
and you see only instances.

But Python does reuse space allocated for integers when it can.  So,
for example, this causes no visible memory growth:

i = 0
while i < 4*1024**3:
    i += 1

If it were possible (it isn't) to get away with doing

    range(4*1024**3)

then the space for those 4 billion *simultaneously-alive* integers
would indeed stick around forever.  Same story for floats, BTW.  It's
the maximum number simultaneously alive that matters here, not the
total number of ints or floats ever created.

In any case, I sure agree this is unlikely to be "the problem" that's
biting Andy.

I can't figure out the magic needed to get dreamweaver mx 2004 and zope 
configured. I am sorry if this information is been already discussed, but I 
can only find old or disjointed information.

I am using the latest 2.7.x zope. and Dreamweaver MX 2004.
I have configured Dreamweaver's webdav access to my site without problems.
What is the story on accessing zope's file (for example index_html) in 
dreamweaver?
Is there other setup issues needed for Dreamweaver to handle zope's 
file/tags?

Are there better options for external editors for zope?

I see some talk about put_factory configuration from years past, but it is 
not clear to me what that is or if it still is needed.

Again, I am sorry if this is rehash, but I would think there would be 
cookier cutter setup steps somewhere.

Thanks in advance

If you have a specific problem then please give a detailed problem 
description and tell us
*what* does not work. As a first step ensure that you are accessing Zope on 
the *webdav* port
and *not* on the HTTP port (see zope.conf).

The recommended way to store Word documents with Zope is using File +

Currently, Zope is advertising "Server: Zope/(Zope 2.7.3-0, python

Apache.

I know that apache can be set to hide its current version.  It would

Where/how do we do it?

It works absolutely like a charm. I don't think you can have a better 
combo than Zope and Dreamweaver.

You have probably not started the Webdav port.

But are trying to access it through port 80. That will seem to work, but 
it doesn't.

Webdav-Source port to be precise. The standard port supports webdav too.
Works like a charm with the correct clients :-)

What Useragent string is dreamcrapper mx 2004 sending btw?
One can add a useragent string to zope.conf and have webdav source
support via web port too.

aj,

My problem:
I can connect to my site via webdav using Dreamweaver, but:
1) can't get it edit files like index_html without renaming them (say index.html)
2) doesn't understand the zope tags in files and gives warnings (tal:XXX).

I was using the main port (8080), but have changed it to port 1980 as described in zope.conf. From the zope console I see:
  
Network Services 
ZServer.HTTPServer.zhttp_server (Port: 8080)
ZServer.FTPServer.FTPServer (Port: 8021)
ZServer.HTTPServer.zhttp_server (Port: 1980)

Using the 1980 port, didn't make any difference.

Thanks,
Doug

I can connect to the site via dreamweaver fine using the standard port and webdav-source port.
However, how do you get dreamweaver to understand the zope files. For example, the no-extension files like index_html and zope tags inside of files.

Thanks!

  Webdav-Source port to be precise. The standard port supports webdav too.
  Works like a charm with the correct clients :-)

  What Useragent string is dreamcrapper mx 2004 sending btw?
  One can add a useragent string to zope.conf and have webdav source
  support via web port too.

Hi all!
Some days ago I ask here for a IIS redirector to Zope

Volker points to me to these url

/http://freshlogic.net/

/because I need a free solution (thanks again Volker!)

But recently these people don't support the redirector for free anymore

Do you know any IIS redirector for free?

Thanks a lot!

And where would one find the source for this information in the Zope

Likely in ZServer or Medusa. grep is your friend.

You could use apaches mod_header to filter that Header or grep the 
source of zope.

Btw. what do you think you gain if you hide that information?

Added security -- same reason why you can setup Apache to not
broadcast what version it is.  There's no reason to broadcast what
versions of software we're running.

The problem is with DreamWeaver/Windows wanting to associate everything
with an extension rather than content.  What I have done for my users to
be able to use DreamWeaver is to have index_html point to index.html by
putting <dtml-var index.html> as the only line in index_html. You have
to do this in each directory or you will pick up the index.html from the
same level index_html is in if you use a url without the page name
itself and don't have an index_html page.

hope this lines up right for you.

eg. a-
      |_ index.html
      |_ index_html
      |_ b
          |_index.html

both URLs /a/ and /a/b/ would show index.html in /a/



 I think you can also set the default page to be index.html instead of
index_html.  There have been addins in the past for DreamWeaver to edit
dtml tags but that doesn't solve the no extension problem.  DreamWeaver
IDs the file by its extension so it can display specific tools for that
type of file:xml,html,cold fusion, etc.  There would need to be some way
in DreamWeaver preferences to associate no extension files as html which
I don't think is possible.

I know many users love to use DW but I usually stick to vi or zmi.

Sorry, "security by obscurity" will not make your system any more

Why not? Its nice for statistics. Unlike Apache, you have no access
to filesystem or other internals of the host via Zope.

I bet you have more potential insecure services on the average
server box. Mail for example...

I remember we once used (paid :-) versions of DW years ago
and reported that problem to Macromedia. But they are constantly
ignorant to technical standards unfortunately. Best advice
is to not buy products from them...

But that doesn't matter one bit. If there is *a door* exploits will be 
run against it - simply because a lot of them are automated and it's 
quick and easy to do so.

If the exploit software exploits software X and the exploit mechanism 
finds out that software X is on the system it is looking at then it 
will try the exploit. No matter what version strings say. The script 
kiddies are dumb, but not that dumb.

Yes, but that's no reason why not to lock down other items as well.

Err. seriously, where is a Zope door unlocked? I mean, every visitor
can find out with little effort if its zope running or something else.
And Zope is probably one of the most secure web application solutions
you could get. (Sure you can drill holes in it if you try really hard
as zope admin :-) But out-of-the-box its really secure. Name any
exploit you know.

Paint a door just in a different color does not really mean you locked
it.

Noone is saying, don't lock it. Noone is saying that removing version numbers
is a solution by itself. But it certainly ADDS something.

If it didn't there wouldn't be such an effort to prevent OS types and versions
from being decoded by passive scanning.

Dreamweaver doesn't deal well with this case; I would avoid the lack of

Hm. most of the time - and in this case - its just overkill. 
The only real gain I see is you save some bytes to transfer
over the web.

Attackers choose the simplest way to get in - and a running zope
just is not. So better spent the time in making all that other
services even close to the secureness of zope. Next you can think
about hiding the version number.

Just my thinking :-)

I don't know of any off the top of my head, but that's not to say that
there isn't one out there that could explot zope in some way from its
header info.  We're just trying to be proactive about things, thus my
question.

thanks for the info.
Yes, I would be interested in your plugin.
I am new (you can probably tell) to the web site stuff. I am pretty sure I 
want to use Zope. I am really interested in Plone, but starting out slow.

I am trying to determine if Dreamweaver is going to make my life easier and 
worth the expense to manage/design as much as possible.

What is the best way to change zope site to extensions? I know when I 
discovered DW couldn't edit index_html, I renamed it to index.html, but of 
course my intial zope site stopped working.

Thanks!

In my limited experience with Plone (it powers my personal site) I 
wouldn't choose it again for what I need there....but I'm lazy and since 
  I put the effort into making it work, it suffices for now.

That's often decided in retrospect.  I think Dreamweaver is yet another 
tool in the developers toolbox.  It has it's uses.  I don't use a hammer 
when I need a screw driver; the skill is knowing when/what to use it for 
and not trying to make it more then it is.

I'll try to write up my madness on zope.org sometime; it definately 
won't work for everyone - but I think it's a solid way of using 
dreamweaver with Zope.  I've got a way of using the Dreamweaver 
templating and Library objects with Zope that I think is pretty cool.
At the end of the day, the tolerability factor is determined by the 
audience of those files.  I did it for web designers - not engineers.

Andrew,

Would you mind taking a few moments to explain why you would not
go with Plone the next time?  I've been resisting the move to Plone
around here (mostly, I think, because it just smells funny to me),
but I need more concrete reasons to make our decision more rational.

Thanks in advance,

I think Plone's great application if it's what you want.  I typically 
want little and wish to build most of the application myself.  I found 
that trying to go that path with Plone was harder for me, as I had to 
learn the Plone way/framework and I wasn't really wanting to sign up to 
do that for the task at hand.  Plone has their way - which 
understandable - it's just not what I was in need of.

Message-ID: <pan.2005.01.05.18.55.50.3531@babysnakes.org>

Hi

forgive me if it's trivial, but I'm a complete zope newbie....

I read in the zope book that if I want to call zpt from a script (in my
case, to render errors in a form) I do something like this:

--
script:

pt = context.body_content
s = pt(zerror="This is an error")
return s

zpt:

<i tal:content="options/zerror | default">error</i>
--

This works without a problem, but it only shows the "body_content" file.
this file is part of a layout (inside a folder) and I want to call the
folder as the url, so it will acquire the index_html in an upper directory.

I tried changing the "pt" variable to context.index_html and calling
"here/index_html/options/zerror" in the template but it didn't show. 

how can I achieve that?

thanx

The recommended way would be:

name = 'blach.pdf'
REQUEST = context.REQUEST
ob = context[name]
return ob.index_html(REQUEST, REQUEST.RESPONSE)

Look at "CMFPlone/zserverPatch.py" how it adds the Plone
version number.

In fact, you should override this patch at it sets the actual
server identification in a Plone installation.

The University here, pays for a site license for DW and other MacroMedia
products so it is readily available here.

My users have been using DreamWeaver since at least DW 4.  The only
changes I have had to make is moving from DW's ftp to WEB DAV since DW's
ftp made changes with every update that wouldn't work with Zope and our
network.  We are now using WEB DAV with the Site portion of DW.  I have
one user using HotDog and we had to install DW on her machine for the
WEB DAV feature since its not incorporated in HotDog.  
Just yesterday we started looking into (free) standalone WEB DAV clients
since the new XP WEB Folders won't try to authenticate unless you create
a new folder and then you can copy files to the Zope.  We found many WEB
DAV clients that would transfer files to Zope but that literally caused
a problem, a file.  Transferring a .jpg into a PhotoFolder showed up in
Zope as a file(octetstream...) not a Photo object.  After finding
references to NetDrive from Novell (lets you map ftp,webdav, other as
local drive in Windows Explorer, not IE) I downloaded that and installed
it.  Graphics transfered using NetDrive retain their content type when
transfered to a Zope server is what I've found so far.  NetDrive was
designed to map a Novell drive without having to have a Novell client
installed.

In summary, to answer your question plain and simple is I use vi when
not using the ZMI. When creating CSS pages I use Layout Master from
www.westciv.com, paste source in Zope and then edit in vi or ZMI. ;-)

No we do not use C extensions.  In fact we can reproduce this behavior
on a fresh install.  On a fresh system create a python script that puts
data in a session object.

s = context.REQUEST.SESSION
t = ' ' * 1024
s['data'] = t
print "foo"
return printed

Then call this script with your favorite bench marking program.  We used
apache bench (ab).  This will cause python2.3 to consume all available
memory and crash or lockup.  The speed at which this happens depends on
the amount of data you assign to 't' and how fast you call the script.
The session timeout does not seem to affect the memory use.  We even
tried setting the session timeout to 1 minute.

In a very basic sense this is all our production server does.  When a
user first comes to our site we query a mysql database for several
hundred values.  These values are then stored in the session object as a
map.  All other pages are built dynamically based on the values stored
in the session object.  

Is the session object system just not supposed to be used like this?

We need to do some back-of-the-envelope math here:

   Estimated bytes / entry:      16
   Estimated entries / user:    150
   Estimated overhead / user:   600
   ================================
   Estimated bytes / session:  3000

How many simultaneous sessions are we talking about?  A few hundred 
simultaneous users could chew up RAM pretty fast.  What is your "max 
number of sessions" value?

Sorry for the delayed response.  I would recommend asking / CC'ing the 
list, so that you get the benefit of the whole community's experience. 
I have CC'ed the list.

WRT to your question:  I don't know of any off-the-shelf way to do what 
you ask.  We have built solutions for such problems based around 
syndicating RSS from "spoke" sites to a "hub" site, but the software 
isn't part of any freely-available offering.

Mike Pelletier has an RDF-based product which might be of interest:

Message-ID: <B04D245FBAA92241833B01C21BEC259E09E312A7@LMNFREX01>

Hi,

I am using Zope 2.7.3 with this configuration :
+ a ZEO instance with one ZODB
+ a Zope instance with Read/Write connections to the whole ZEO ZODB
+ several Zope instances with Read Only connections to one folder of the ZEO
ZODB (+ a small local ZODB for the root folder, that never changes)

It looks like some object changes (specially objects located in CMF
portal_skins subfolders), are not always "seen" from one connection to
another (either on the Zope instance where the changes were made or any
other Zope instance).

The problem is fixed when I minimize the connection caches.

Anyone knows what could cause such an issue ?

It appeared with Zope 2.7.3... (was ok on 2.7.2)
But as we did other changes at the same time, I am 100% sure it's because of
the Zope upgrade itself.

Thanks a lot.

Pascal

I'm running Zope with Plone, specifically the windows installer

This is because the first time you make a request to your Zope instance, it
retrieves lots of objects from the ZODB (file).
For subsequent requests, most of this objects are cached in a connection
object cache.

See your /Control_Panel/Database/manage_workspace, select a database, and
then have a look at the Cache Parameters tab.

There is one cache per connection, and usually there are 4 connections to
the ZODB.

But in general, under reasonable load on your site, the cache should be
efficient.

I don't know of any way of optimizing this.

Hope this helps.

I'm running Zope with Plone, specifically the windows installer
version distributed on the Plone website. The first time I hit the
site (even the ZMI) the first page takes a long time to load;
everything after that is speedy.

I'm thinking it's some sort of caching issue but I'm not sure where to
look to remedy the probelm. I am not running debug mode either.

We encountered the same problem, and agree that its probably a cache-loading
issue.  We never discovered the cause, but we have a work-around:  we run a
cron job which does an http request to grab a page from the web site every
10 minutes - this seems to keep the cache 'fresh'.

Are the modified objects ZODB-based skin methods, or the 
filesystem-based analogs in a FilesystemDirectoryView?  I don't know of 
anything which would explain your behavior for ZODB-based objects;  such 
staleness would imply a bug in ZODB invalidation logic. 
FSObject-derived items have a "proxy" stored in the ZODB, which caches 
the "real" method object as a volatile attribute;  cache minimization 
would cause those volatiles to be discarded and recomputed, and might 
therefore contribute to the behavior you describe.

I was thinking of doing that, but it seems like such a dirty hack ;)

It's on the first load and also if I leave it alone for a couple
hours. Does anyone have suggestions for fixing this issue?

Hmm.  That explanation doesn't appear to match the Subject line -- and
that's why you're getting explanations about initial startup.

Taking the Subject as being the real issue here, there's another
problem that may be unique to Windows:  for inscrutable reasons at
inscrutable times, Windows routinely swaps out RAM that hasn't been
touched by a process "for a while", and regardless of whether it
actually needs the RAM for something else.  You can watch this by
bringing up Task Manager, and ensuring that the "VM Size" (amount of
address space committed byo the process) and "Mem Usage" (amount of VM
address space actually in RAM) columns are displayed.  The latter can
(although this is extreme) shrink to kilobytes if a process is idle
"long enough", no matter how much VM the process has committed, and
even if the machine is otherwise idle the whole time.

In a previous life, I worked on an NT-based call-center telephone
speech recognition system.  That's a very intense application,
requiring 100s of MBs of RAM.  Machines running it ran nothing else,
and had plenty of RAM.  Nevertheless, in the middle of the night when
call traffic was light, NT would swap the whole thing out to disk. 
Then a call would come in, and it could take literally minutes for NT
to swap enough of the app back into RAM to process the call.

I don't recall whether we ever found a slick solution.  The first
brute-force wormaround worked pretty well:  when the app was otherwise
idle, we had another process trick it into thinking it was getting a
phone call and hearing speech.  That kept most of it RAM all the time.

Maybe, a bug with "read only" connections?

Try to switch to all "read/write" connections and see whether
the problem disappears.

I do not yet understand what you want...

Usually, the overall layout is defined in a macro
and individual page templates use this macro and fill slots of it.
Maybe, you read about "metal:define-macro", "metal:define-slot",
"metal:use-macro" and "metal:fill-slot" in the Zope Book.

Otherwise, if you do not want to call "body_content" but
"index_html", then you simply use "pt = content.index_html" (provided
it is a ZPT, too).

>I tried changing the "pt" variable to context.index_html and calling
>"here/index_html/options/zerror" in the template but it didn't show. 

In "index_html", you would access "zerror" also via "option/zerror".

When your "index_html" would call "body_content", you would
need to pass "zerror" again.

And I am not surprised at all:

  You allow an unlimited number of sessions.

  Your session timeout is 45 minutes

  "ab" does not honour the "set cookie" requests for the sessioning.
  Thus, each request creates a new session.

  This way, it should not be difficult to use
  a large amount of RAM.
  My Zope serves about 500 request/s, 30.000 request/min
  and 1.350.000 requests in 45 min.
  You must expect a number of sessions in this order.

We use the session system in quite a similar way -- without problems.
But, we have a maximal session count of 5.000.

We, too, observe some increase in memory requirements which we do
not yet understand: memory seems to increase from about 300 MB
to about 600 MB within a week. Therefore, we restart
once every Sunday night. But, the problem has not yet been pressing
and we did not yet seriously tried to understand it.

I am trying to move a site from Zope 2.6.1 on Linux to Zope 2.7.3 on

Whenever I attempt to view a user in any acl_user folder on the XServe

the old server are unable to do so on the new one.

Here is the entry in error_log:

The code in question is trying to match a version number from
a file called "version.txt" in $SOFTWARE_HOME, which is set
in the runzope file.  Check the runzope file you are running
above for $SOFTWARE_HOME, then open the version.txt file and
tell us what is in it.  It probably does not match the regular
expression:

expr = re.compile(
             r'(?P<product>[A-Za-z0-9]+) +(?P<major>[0-9]+)'
             '\.(?P<minor>[0-9]+)\.(?P<micro>[0-9]+)'
             '(?P<status>[A-Za-z]+)?(?P<release>[0-9]+)?')

You can probably get past this problem in the short term by
just deleting that file.

HTH,

Check the archive, I asked that question before christmas. The problem
is the version string in a file of lib/python/... (I don't know the
exact filename). Also there is an existing Bugreport, the problem is
the Solaris echo-program (IIRC).

Yes, getting rid of the file (or renaming it, in this case) allows
Zope to run.  Not unsurprisingly, when I open the ZMI (see, I'm
learning the buzzwords already!) the  Zope version is listed as
'unreleased version'.

I assume there's a way to specify that version file manually.

OK, I got Zope up and running with the assistance of the mailing list.
 Thanks guys.

I have successfully added a Plone site, but when I tried to create a
new user through the web interface I got the following message:

You have been registered

Site Error

This site encountered an error trying to fulfill your request.  The errors were:

ErrorType
    ValueError
ErrorValue
     Unable to find prefs_users_overview

The URL is http://...ploneSite/join_form

Do I need to something else before a Plone site is usable?

Therefore

here/index_html has not options since it is not called as a method.
If I understand your problem correctly, you shoud do something like:

script:

pt = context.index_html
return pt(zerror="This is an error")

zpt:
<div tal:define"error options/zerror | nothing" >  
  <i tal:content="error"  tal:condition="error" />
  <div tal:content="structure here/body_content" />
</div>

Message-ID: <002001c4f432$8c626fa0$0201a8c0@SPINNEKOP>

hi,

I have a question of virtual host monster in combination with a virtual plone site, in combination with an apache site

I have an url http://212.100.163.214:8080/help  that should be directed to http://212.100.163.214/help    : this means that everytime i go to the url or http://212.100.163.214/help , I should arrive to http://212.100.163.214:8080/help    , which is a zope site. I have installed vhm in the root folder of http://212.100.163.214:8080 and i have as httpd.conf zope-part : 



LoadModule proxy_module /usr/lib/apache/1.3/libproxy.so
AddModule mod_proxy.c
<VirtualHost 212.100.163.214>
            ServerAdmin johan.boeckx@be.easynet.net

ProxyPassReverse / http://212.100/163.214:8080/VirtualHostbase/http/managedrouters.easynet.be:80/help/VirtualHostRoot/

</VirtualHost>


Nevertheless, when i try to access http://212.100.163.214/help/  , I see in the logs of apache : 

[Thu Jan  6 22:53:18 2005] [error] [client 81.188.66.90] File does not exist: /opt/jffnms/htdocs/help

, which is the document root of the first site, while i need to arrive on the plone-site.
Anybody know what i do wrong ?

Greetings,

Yes, I understand that ab will not set the cookie and each request will
look like a new connection to Zope.  That is not the point.  The point
is that whatever memory is used by these sessions should be released
once the session has expired.  This does not seem to happen.  Memory use
just grows and grows until the server dies.  We turned on the debug
output in Transient.py and the buckets seem to get expired as expected
but like I said memory used just grows without bound.

For example if I have ab make X requests, X new sessions are created and
memory use goes up by 100MB.  I also see about X objects in the
transient object container.  Now I wait for the sessions to expire based
on the "Data object timeout value".  Then I make a few calls to tickle
the Transient system's garbage collection.  The objects in the toc goes
down but memory use does not.  Some have posted that python does not
release memory it just reuses it.  Well, when I make X more requests the
memory is not reused.  Now it is using 200MB.

Consider the problem pressed.  ;-)  

Well, I guess I'll just restart Zope every day for now.  

Could it be possible that the BTrees code which is written in C is
leaking?  Memory leaked here would not show up as refcounts in Zope
right?  It is FULL of malloc and free calls.  Isn't this a fairly new
addition to Zope?

Thanks again for your help and insight!

Hi,

I'm looking for building blocks to use for our "shop"-management solution. Does anybody know a solution/product to print out from Zope structured documents like invoices, open-balances, cash-flow reports ... .In more general the tool I'm looking for should be able to build documents (even multipage) with report-headers and -footers and page-headers and -footers, running sums, sorts ... . These documents should be send immediately to the printer (not displayed in the browser and waiting for the user to hit "print"). The source of data is a MySQL database.

By the way, I use MailManager to handle our mail traffic - a cool product.

Thx

This may mean you have a folder or object named 'user' around. Remove

Erm, I did indeed have a folder named "user," and renaming it worked 
like a charm.

After fighting with the joys of DTML's magic namespaces for an hour 
yesterday, one would have thought I'd have learned my lesson. But no.

Thanks!

If I understand correctly, this will first print the "zerror" variable,
and then the content of here/body_content. I want the error to show in the
body of the form (inside body_content). anyway, I solved it like this:

<td tal:define="zerror options/zerror" 
	tal:content="structure python:here.body_content(zerror = zerror)">
	budy content
</td>

now I can call index_html from the script and add tal:condition (not shown
above) to test for the existence of "options/error" and call body_content
like the example above.

thanx

that's how I solved it eventually:

That's exactly what I do for my zope-site...

> 
> </VirtualHost>

First thing: The ProxyPass line has an invalid IP: 212.100_/_163.214
anyway I'm using something like:

LoadModule rewrite_module /usr/lib/apache/1.3/mod_rewrite.so
<VirtualHost 212.100.163.214>
	ServerAdmin ...
	DocumentRoot ...
	ServerName ...
	RewriteEngine on
	RewriteRule ^/(.*)
	http://212.100.163.214:8080/VirtualHostBase/http/212.100.163.214/help/VirtualHostRoot/$1
	[P]
</VirtualHost>
<VirtualHost *>
	DocumentRoot ...
</VirtualHost>
	
This rewrites any access to the normal IP to the Zope/help thing and
makes that the server-name again (so nobody sees that it's Zope

I know as much about the gory details of Python's memory-management as
anyone on Earth, so you can believe this:  if anyone gives you a
catchy one-line summary, don't believe them.  Python has many distinct
memory-management subsystems, and details are crucial.  In addition,
Python builds on top of the platform C library's malloc/free/realloc
system, and that builds in turn on the platform operating system
policies.  If you pursue it, you'll discover that it's a long
discussion just trying to figure out what "release memory" could
possibly mean.

That said, it's not generally expected that the virtual memory
highwater mark (which I'm guessing you're really talking about when
you say "now it is using 200MB") will grow rapidly and consistently.

Yes -- and if you use an old enough version of ZODB, it's guaranteed
to leak <wink>.

For the most part, it should:  BTrees are built out of Python objects,
each with its own refcount (as is true of all Python objects).  To
Zope, BTree building blocks look like all other kinds of persistent
Python objects.

I haven't done this for a while, but when leaks in the BTree code were
still suspected (they truly aren't any more), I used to run the ZODB
test suite under a debug-build ZODB and a debug-build Python, for days
at a time in a loop.  There are special gimmicks you can use in a
debug-build Python to detect leaks.  This did find leaks, too.  I
stopped doing this after the last leak it pointed at took days to
track down, and turned out to be in a BTree endcase soooooo rare that
it may never have occurred in real life (but did occur once in one of
the test cases for "pathological" BTrees).

That doesn't mean there can't be more leaks, but it would be pretty
amazing if there were still a leak on any common path thru the BTree
code.

> It is FULL of malloc and free calls.  Isn't this a fairly new addition to Zope?

No.  The BTree code is really part of ZODB, and has been there (as far
as I know) forever; Jeremy Hylton and I did a lot concentrated work to
squash memory leaks in ZODB (including its BTree code) a couple years
ago.  The BTree code has been very stable (== has been changed very
little) since then.

Subject: [Zope] Zope 2.7.3 + Apelib 1.0 - Intermittent data loss in
	acl_users obj
Message-ID: <200501070938.05964.chris.kratz@vistashare.com>

Hello all,

We've been using Apelib with Zope 2.7.3 for several weeks on a production 
site.  We've been having problems with password changes disapearing 
intermittently from one day to the next, and whole user accounts being lost 
periodically.  Up until today, we thought it was a bug in our own code.

After being able to reproduce the problem outside of our code (using the zmi), 
we started looking at Zope and Apelib.  We have come to the conclusion that a 
standard acl_users folder is not always correctly persisted when using 
apelib.  Whether or not we are right, the following is how we understand 
things to be working at this point as well as an ugly hack that seems to fix 
the problem.

We are using the file system persistence method of apelib for our test bed.  
Using the file system persistence and grep, it is a very simple procedure to 
add a user, change a password through the zope zmi and verify that the 
changes to acl_users were persisted by inspecting the file on the file 
system.  There is no pattern, but almost always after several changes to a 
password or adding several users, the changes stopped being persisted to the 
file.  Stopping and starting zope at any point from then on loses those user 
accounts or password changes that were done after the persistence stopped 
happening.  We verified that the objects are correctly changed in memory, 
because subsequent use returns the modified data.  Also, updating the 
properties on an acl_users folder (going to Properties tab and clicking Save 
changes) causes all changes to be written out including password changes and 
user account additions and removals.

We are no experts on this code, but it appears that the serializing code in 
apelib only is inspecting the _p_changed flag on the user folder itself and 
not on the individual user objects persisted within.  In a standard zodb, it 
appears that every user object is persisted separately.  So, a change to the 
user object only marks that user object as changed, not acl_users.  But in 
apelib, the acl_users folder is persisted as a whole with all user objects as 
the contents.  With a standard ZODB, any updates to user objects are 
persisted at the user object level.  The same thing appears to be happening 
with apelib except that it appears that apelib when persisting objects only 
examines the acl_users folder and none of the user objects for changes.

It may be a red herring, but by adding self._p_changed=1 to _doAddUser, 
_doChangeUser and _doDelUsers in class UserFolder, we were no longer able to 
break it (ie changes were always written to file). Since apelib treats a user 
folder and all it's user objects as a single entity on the file system, this 
seems to address the problem.  What's even more troubling is mixing this issue 
with multiple threads which caused all kinds of authentication errors when 
creating new accounts.

We are wondering if anyone else has run into a simliar issue, and/or whether 
there is a better way to solve this then to modify User.py.   It seems like 
the better approach would be to modify apelib, but we haven't been 
successfull up till now.

Message-ID: <37DB2705555B4C44842BEA017A6E80DB047F94@exch2-bllon.uk.easynet.corp>


hi - i have been searching the websites and google and the zope/plone
product pages for a "product" which will work like a groupware/colloration
system - much like Yahoo Groups. 

features desired include:
	* email and list messaging
	* filestore for multi-type documents (eg pdfs)
	* shared calandars / meeting

i have pnly recently beocme familiar with zope and plone and have a site up
and running but which is "presentation only" for the pubnlic - a groupware
system would be much more interactive ... 

i know i can install things like PloneMail or similar ... but i don't know /
want to program the underlying mechanisms to propagte meeting invites etc
etc ... 

the CPS website is not very open - i can't see a list of features or
screenshots or a demo site. 

does anyone know if something like this exists?

i am keen on a zope/plone solution because it would keep things simple and
reduce the dependence on multiple platforms... i want to stick with an
OS-independent zope/plone .. benefit from the zope scalable middleware and
have simply replication/backup options that zope/plone gives me (data.fs?)

thanks

Let's not go into the gory details.  Another discussion of the
complexities of memory management will not be productive.  The fact
remains that if given enough time Zope will use so much memory that it
crashes the server.  I've reproduced this on at least 3 Linux servers
with a clean install of Zope.  The pattern SEEMS to be the more data I
put in a session object the faster the server dies.  This can not be
normal behavior.  I'm used to servers running for months.  I have to
restart Zope every 3 days at least.  I need to at least have a long
weekend away form this thing!  ;-)

Can anybody please verify my results.  I've given a very simple test
case.  If I'm only one in the world that can cause this to happen then
fine.  At least that narrows my search to something internal to our
system.

Please don't take offence I'm sure the BTree code is really cool.  I'm
just grasping at straws.  When this problem started I was told the
problem must be in MY code.  So I removed ALL my code and made a very
simple test case that reproduces the problem.  Then I was told well you
just don't understand how memory REALLY works.  At this point I don't
really care how memory really works.  I just want to be able to put data
in session objects without my server crashing.

Run my test case and see what happens.  I double dog dare you!  ;-)

Two (late) solutions:

1) If you don't need the batch addition support, just comment out the 
section of create.pt that calls gethostname and the whole div that 
supports batch addition.

2) If you're more adventurous, add to __init__.py security declarations 
to make the needed module functions public. The code will look like:

from AccessControl import ModuleSecurityInfo

ModuleSecurityInfo('ExternalFile').declarePublic('gethostname')
ModuleSecurityInfo('ExternalFile').declarePublic('illegalCharsAsString')
ModuleSecurityInfo('ExternalFile').declarePublic('omittedDirNamesAsString')
ModuleSecurityInfo('ExternalFile').declarePublic('omittedDirPrefixesAsString')
ModuleSecurityInfo('ExternalFile').declarePublic('omittedDirSuffixesAsString')
ModuleSecurityInfo('ExternalFile').declarePublic('omittedFileNamesAsString')
ModuleSecurityInfo('ExternalFile').declarePublic('omittedFilePrefixesAsString')
ModuleSecurityInfo('ExternalFile').declarePublic('omittedFileSuffixesAsString')

ModuleSecurityInfo('ExternalFile').apply(globals())

Then, in www/create.pt, add a line like:

   <tal:work define="global ef modules/Products/ExternalFile" />

change

tal:content="container/gethostname"

to

tal:content="ef/gethostname"

and ALL the code like:

tal:attributes="value container/illegalCharsAsString"

to

tal:attributes="value python: ef.illegalCharsAsString(container)"

If you don't want to mess with the security declarations, you could also 
just edit www/create.pt to remove the section that prints the hostname 
and all the "tal:attributes..." that supply default values in the batch 
section.

I think people are trying to help, and you need to follow up more. 
For example, I didn't see a reply to Tres's questions in this thread,
and I didn't see what looked like a particularly relevant reply to
Dieter's observation that the test setup appears to provoke an
unbounded number of sessions each with a 45-minute timeout (although
Dieter appeared to miss this part of the message he was replying to:

    The session timeout does not seem to affect the memory use.  We even
    tried setting the session timeout to 1 minute.

your reply to him didn't have any indication of how many
requests/sessions were getting created; and you didn't respond to his
point that he limits max sessions to 5000 -- Tres also asked about max
# of sessions).
...

> Please don't take offence I'm sure the BTree code is really cool.

Oh, no offense at all!  C code usually leaks like a sieve when it's
new <wink>.  I was just trying to steer you away from the BTree code
in this case, because it's not new, has benefited from a lot of work
to plug leaks, and just isn't a high-probability suspect anymore. 
BTW, you *do* see BTree building blocks from the debug control panel;
they're in the lines like:

BTrees.OOBTree.OOBTree  2019    11997   +9978
BTrees.OOBTree.OOBucket         1297    5512    +4215

Sorry, but I don't have time to dig into this at all.  My replies have

Hi
I have some kind of problems to understand how Zope's security rules

If I have these distribution:

root
    Blogs
       Blog1
       Blog2
       Blog3

where
Blogs: Folder
Blog1, 2, 3: Coreblog product

How can I configure the security to have 3 users (User1, User2, User3) 
who can log on ZMI to manage their weblogs?

I suppose (but don't work properly for me) I need to create a user 
folder on Blogs folder and create 3 users on it, isn't it?

Thanks!

Oh I know and I'm grateful.  Please don't misunderstand.  My frustration
is with the situation not with the members of the list.  I have a high
respect for the Zope community and especially those that take to time to
help with people's bizarro problems.

The upper bound on the sessions is not relevant in my opinion.  We have
set it to unlimited because no matter what we have set it to in the past
we always seem to spike up to it when nobody is around to delete the
session objects by hand.  This happens because of something very
specific to the wi-fi hotspot market that I'd rather not go into.  In
most cases we avoid these spikes but it can happen so we do not set a
limit.  99.9% of the time we have 500-2000 objects in the transient
object container.  

Dieter is right.  My test could provoke an unbound number of sessions
but it doesn't because of the way the test is run.  I'm not trying to
simulate one user making 1000 requests.  I'm trying to simulate 1000
users making one request which should produce 1000 sessions.  These
sessions are allowed to timeout and then we create 1000 more.  If this
cycle is repeated enough times all memory is consumed and the server
crashes.  This happens even if there are hours between cycles.  The
memory use never goes down it just grows even though the number of
sessions never goes over 1000.  

> How many simultaneous sessions are we talking about?  A few hundred 
> simultaneous users could chew up RAM pretty fast.  What is your "max

>
> Tres.

Sorry, Tres's.  Let me explain.  The max sessions or the amount of data
in each session should not matter.  The server should reach some steady
state value of memory usage.  This is because you always have new users
coming to the site which creates new session objects, but on the other
end you have users that have gone away and so their sessions expire.
When one restarts the server I would expect the steady state to happen
within 3 or 4 times the session timeout value.  My problem is that this
steady state never seems to happen.  Memory use just goes up and up.


I have found something today!  We store some images for our site in a
MySQL database.  I noticed today that these images (some could be large)
are copied to the session object.  This was probably done to reduce
queries to the database.  There are so many caches along the way (
browser, Zope, zsql...) that this is probably not needed.  I turned this
feature off.  At least this should push the horizon off a bit.  Time
will tell.

Perhaps stated too strong that's just my impression.  I was referring to
the long posts last month about how Zope, python, and Linux manage
memory.  That's all voodoo to me.  I just don't understand how this
simple test can cause so much memory to be used.

Can't blame you there.  I don't have time for this either.  

I'm going to restart my Zope server just for good measure and go to the

Maybe, "reportLab" can help you.

It will not perform out of the box what you want but
you can use it to automatically create PDF documents that

That should work fine.
Please be more specific about what you mean by "doesn't work

I've had a similar problem with HomeSite... I turn off Passive FTP on

Make sure to open 8020 and 8021 in the gateway.

Hope that helps.

You have been right.

The leak is caused by a bug in
"tempstorage.TemporaryStorage.TemporaryStorage._takeOutGarbage"

  It performs the zero refcount check for a child of a deleted
  object *before* it has decremented the refcount. As a
  consequence, it does not release children of a deleted object.

I attach a script that reproduces the problem in an easier way.
Calling it with "bin/zopectl run" will consume about 200 MB of RAM
for about 5 min.

I also attach a patch.


I will file a bug report.

A solution you could look at is openoffice.

You could set up an openoffice listening on a port. Then you could 
connect to it via Py-UNO bridge, open a template, fill it, and invoke 
the printing.

Of course, all of this could be done without any interface showing to 
the user. I'm not sure there is any product available doing this at the 
moment, but you could look at the Archetypes code for some ideas.

Subject: [Zope] _finish and _abort not called in a TM subclass
Message-ID: <41DF5630.7010701@icube.it>

Hi all.

I'm trying to figure out the proper way to use the Shared.DC.ZRDB.TM.TM 
mixin class. According to the documentation, I should derive from that 
class, redefine my _abort and _finish methods, and then call the 
_register method whenever it is needed.

I've created the following sample product, named CacheProduct. It has 
two methods which can be called from the web, registerFromWeb and 
resetMe. The first calls the _register, the second puts the 
self._registered variable to 0.

I've also added some prints, in order to check the results.

If all goes well, I should see something like:

before: 0
after: 1
_finish

However, if I use ab to do a check, like

ab -c 10 -n 1000 http://server:8080/CacheProduct/registerFromWeb

I can see:

_before: 1
_after: 1

which should never happen. Also, I don't see the required calls to 
_finish. After some request, the _finish reappers, only to disappear again.

Has anyone any suggestion on this topic?

Regards
Marco

I use it for connections to an SAP system -- and it works well.
There are indeed no needs other than to define '_finish' and '_abort'.
Note, however, that TM instances should *NOT* be persistent!
Persistent TM instances can behave weird!


I assume that the "0" and "1" above refer to values of "self._registered"?
If so, then for some unknown (and not understandable) reason,
the interaction of the transaction's "commit/abort" with your TM instance
did not work correctly. Maybe, your TM instances are persistent?

Yes, I have a lot of ZClasses in my product and need to re-use it for new product.

This looks as if you can't create two identical copy obiviously this way 
likely because
the class ids must be unique. No further idea about ZClasses. Maybe you can 
create a new
product instance and then copy file by file using cut&paste...

I doesn't work too. When I'm trying to copy my ZClasses it fails with
CopyError: The item ... does not support this operation.

Well, this does not make much sense, the ZClass id is the class
name it represents. Its a bit tricky anyway and most people
will tell you not touch zclasses at all. 
Why dont you derive from the class? This is after all, what
OOP is all about...

My problem was exactly that: I was deriving from SimpleItem and TM, 
therefore the weirdness.

Thanks for your insight on this topic.

There is no instance for zope2.7, read
/usr/share/doc/zope2.7/README.Debian.gz for information on upgrading
2.6 to 2.7

I installed python 2.3.4 and then zope 2.7.3 from source and ran 
mkzopeinstance.py, but am experiencing a problem with privileges. I 
gather that I have to change some, but I do not know exactly how to do 
that. I have looked at

http://www.plope.com/Books/2_7Edition/InstallingZope.stx

And this post:

http://www.gossamer-threads.com/lists/zope/users/177930

...but am no clearer.

Runzope results in:

IOError: [Errno 13] Permission denied: 
'/home/mdl/zope-instance/var/Data.fs.lock '

Also, is there any special procedure for removing an instance?

Make sure that the ...var directory is owned or accessible (chown/chgrp for
linux/unix type systems) - read/write by 'zope'

This usually happens if you install or run Zope as root which is not 
recommended (and documented
in various places).

Yes, I did read that. I downloaded tarballs and worked out of my home 
directory but (being a novice only) didn't find a better way than:
sudo make install
make install wouldn't complete.

The former reply already answered your question:

 - you installed Zope as root

 - all your files are installed as root

 - if you start Zope as non-root then Zope won't start because it can not
    open Data.fs for writing because 'var/*' is not writeable.

Either change the owner of the installed files or change the permissions
or use the installation method using a dedicated INSTANCE_HOME which is
the recommended way to go. Both is explained  here:

Subject: [Zope] Fancy selection with checkboxes
Message-ID: <2469.1105373690@www74.gmx.net>

Hello Zopistas,

I have an hierarchical structure (e.g. folders).
With this structure I want to generate a tree in Zope, where each item has a
checkmark.

If I select one checker, then all items below it should be selected, too.

If I then uncheck one checker, then the checker above that, should appear
gray.

Maybe you know this tree from graphical tape backup applications.

Is there a product for zope, which helps me generating such a tree?

Regards
Florian Reiser

This is basically an issue that you would solve on the client-side using 
Javascript.

That's the endless discussion of detailed memory-management semantics

Subject: [Zope] ZSQL and python script performance
Message-ID: <BE08681E.C314%s.morris@bangor.ac.uk>

Hi,

In an attempt to speed up an application I came across a bottle neck with
Python Scripts in Zope.

Using apache's 'ab' utility I tested a simple query (sql_course_components)
directly with the following URL:

ab -n 20 -c 4  
'http://myserver/portal_skins/acs/sql_course_components/manage_test?gcom_id=
19030&term_code=200405&SUBMIT=Submit+Query'

-----    Requests per second:    23.22 [#/sec] (mean)


Using a Python Script (ptest) to return the result from the query is much
slower:

return context.sql_course_components(gcom_id=19030, term_code=200405)

ab -n 20 -c 4 'http://myserver/portal_skins/acs/ptest'

-----    Requests per second:    2.59 [#/sec] (mean)


I tried the same test with an external method with similar results.

Why is there such a big difference between accessing the ZSQL query directly
and using a python script (which is needed to process the query in the real
application) to return the query?

TIA,

Sion

Subject: [Zope] Generating Short (unique) IDs
Message-ID: <753ca72f0501100953acfa150@mail.gmail.com>

I'm currently running a Zope CMF/Plone site, here's my situation:
I have a folder that contains several of a custom content type I
created called an "EscalationDoc". What I plan on doing is creating
another folder to store another custom content type called
"EscalationID", each EscalationID will be linked to an EscalationDoc.

The reasoning for this is I need to be able to swing what
EscalationDoc an EscalationID points to. My problem is that Zope
generates very long IDs, like "escalationdoc.2005-01-07.0744968113".
These IDs will need to be remembered and entered by humans so I need a
short, sequential, unique IDs.

If I could use some sort of mutex in Zope I could probably figure this
out, but I'm not aware of any such mechanism.

Any suggestions?

Zope Book:
  ...if you upload an HTML file "foo.html" via FTP to a place
where "foo.html" did not previously exist, it will be created (by
default) as a DTML Document object, whereas you may want it to be
created as a Zope Page Template. Zope provides a facility to specify
the object type created on a per-folder and per-request basis
(PUT_factory) that is detailed in this chapter.

Instead of installing NetDrive you could create a PUT_factory script
that will determine what type of the object you want (based on its extension or
folder name).

No, there is no combination of transaction-aware mail transport like 
MaildropHost does combined with authenticated SMTP I am afraid.

There's no hooks into the transaction machinery on that one, so you 
could still run into the "multiple emails" problem. And it seems to 
spawn threads from within Zope itself for its "asynchronous delivery" 
mode. Doing that kind of thing has always scared me :)

Zope has n build in HTTP server so you don't "need" Apache either.

But if your requirements states that you "need" to run Zope and ISS
on the same server (which isn't such a uncommon scenario after all)
they can't chare the same port, a proxy is the best way to go.
Unfortunatelly there's not a open source one out there (yet).


Garito,
Have your had a look at http://www.isapirewrite.com/.
I think it accuallt does proxy.

They have a lite version that is free of charge, but
it doesn't support virtual sites.

Regards,
Johan

Here is a tutorial on using javascript with html forms:

http://www.webdevelopersjournal.com/articles/jscript_forms1.html

You can also google for javascript code (many web sites offer free js
routines which you can modify to suit your needs).

Subject: [Zope] Zope xmlrpc crashes without traceback
Message-ID: <41E3F1BF.70501@gims.com>

Hi.

We are using a javascript xmlrpc(VCXMLRPC.js) library to essentially 
communicate with zope to retreive and display records in a browser. 
After a while, Zope just crashes without warning or any traceback of 
what caused the problem. It completely dies. When running in a command 
prompt, it dies silently as if the python interpreter crashed.

We're running version 2.7 of zope with Python 2.3 on multiple window$ NT 
servers.

Has anybody got a solution for this problem?

Which minor version of Zope 2.7 do you run? There were package-problems 
with the python-xmlrpc-package in at least 2.7.0.

Below is another javascript my associate found recently on the WEB at

http://tech.irt.org/articles/script.htm

 that might be helpful to you or others.  Although the example shown
below is not checkboxes you might be able to find more helpful
information on checkboxes at that URL .

  The script Below lets you insert a value into a drop down list from an
input box.  The drop down is populated from a database field in this
case.  This functionality is similar to Access database where if the
value you want is not in the drop down it can be added by typing it in
the top of the drop down. The javascript will add the input box value
onChange to the drop down and it will make that input the selected
value.  Once this new value is added to the database that value is
available in the drop down box from then on.  Also, if no value is put
in the input box then the selected value is an empty string.

<input type="text" name="newvalue" value="" size="30" />
<select name="f1" size="1" onChange="document.dbaddform.newvalue.value=document.dbaddform.f1.options[document.dbaddform.f1.selectedIndex].value;document.dbaddform.f1.value=''">
  <option value="" selected="selected">           </option>
  <dtml-in myDBtable_column_dropdown>
    <option value="<dtml-var my_column_value>"><dtml-var my_column_value></option>

Subject: [Zope] TM and commit/abort regarding RDBMS
Message-ID: <41E4F648.7090403@icube.it>

Hi all.

Thanks to suggestions provided by Dieter on this mailing list, we've 
been successfull in creating transaction-aware objects, which correctly 
register.

My next question is where I could find more information about the 
protocol used by Zope/ZODB with TM-aware classes. I think it is a two 
phase commit, but, in this case, I've some doubt.

The two phase commit, IIRC, works as follows:

phase 1) all the involved parties in a transaction are asked if the 
transaction should commit or abort

phase 2) if all the parties agrees on commit, then commit (i.e. call the 
commit for) all objects, otherwise abort.


Now, if I understand correctly, phase 1) is done in the tpc_vote. 
According to the implementation of some DA (ZMysqlDA, ZPsycopgDA), the 
tpc_vote is actually not defined, therefore it will always vote for 
finalizing.

At this point, all transactions will try to commit... including the open 
database transaction.

The question are two:

1) where can I learn more about this process inside Zope?

2) is there a scenario where a commit from Zope will face an abort from 
the RDB (i.e. Zope will call the commit, and the RDB will refuse due to 
concurrency problems) ?

Thanks to all for patience and support.

Regards
Marco

Hi,

i' am using Zope-2.7.3 and i wan't my client-storages to be connected at
zope-startup.
In Zope-2.6.3 i used "open_at_startup" in DBTab but this option seems not to
be included
in release 2.7.3, however i can't find it in component.xml. If i add it to
zope.conf anyway i get
an exception.

Any suggestions?

What do you mean by "open_at_startup"?
If you configured the storages in zope.conf,
you go to ZMI and add a DBTab Mount point,
check all storages you want to mount 
and add. From now on the clients are connected
each time zope starts.

The option "open_at_startup" means that the client-databases are opened at 
zope-initialization (not when zope is already up). If this fails zope won't
come up.  
That feature is useful if Zope shouldn't run without an paticular storage.

I haven't had anyone ask me to develop on Plone.

If portal-ish/CMS features are needed and the choice is left to me I 
choose to develop on CMF proper.

This works the same if you do it like I described. Once you use the
database, it is required for zope to start up. e.g. Zope will wait
until the database (zeo) is ready.

Hi Andreas (and anyone else who does security releases)

Might I suggest also announcing this to bugtraq@securityfocus.com?

Also, it would be handy for those of us that use mail server plugins to 
cut down on duplicate messages if you could send messages to the 
announce list that don't CC the zope list, or any other bulk list. This 
message got filed in with the bulk stuff and so I haven't seen it for 
weeks :-S

cheers,

Can't say I blame you ;-)

What do you use for schema-driven content types?

If the question is "do you use Archetypes" then the answer is "no". 
That's not meant as a judgement - I simply haven't had any problem that 
wasn't solved by using mechanisms found in the CMF itself...

What's the official work on what version of MySQLdb and ZMySQLDA you 
should use with Zope 2.7 (which uses Python 2.3)?

If i using the option "open_at_startup" my stupid-log under 2.6.3 shows
"client-connected" before ZServer is up on it's desired port. Without this
option the connection
takes place after ZServer is up on it's port, that the significant
difference. 

Sometimes there is a time delay of a few minutes after zope is up before the
connection
is made (the mounted storage is about 6GB ;-)). I can't except these delay
so i packed this into the initialization part (before zope is up) with the
option "open_at_startup". 

So back to my first question, where ist that option gone in Zope-2.7.3?

any ideas?

MySQLdb-1.0.1 should work fine, though I prefer that you use 1.1.8.
Since ZMySQLDA actually uses the _mysql module (C API), and most of
the differences between 1.0 and 1.1 are in the Python layer, I don't
think it really makes that much difference.

ZMySQLDA hasn't been updated in two years because, AFAIK, there aren't
any bad issues in 2.0.8 or 2.0.9b2. I might revisit ZMySQLDA in the
next month or so.

If there *are* issues, then report them here:

I ran the script on Linux against both Zope 2.7.0 and 2.7.3 and
according to top only some 21 MB of RAM was used up.  (I ran
"bin/zopectl run tempstorebug.py" in the instance home.)  We have a
similar problem w/ Zope leaking memory and our application uses
sessions a fair bit, so better ways to confirm that this patch fixes
the problem would be appreciated.

Zope 2.7 binds the server ports much earlier in the startup process than 
it used to.  The current version of the option is the 'wait' key of the 
'zeo-client' section of zope.conf;  it causes the database / storage 
intialization to block while establishing the connection and verifying 
the cache, but the intialization itself starts *after* binding the 
server ports.

A minutes-long startup is likely due to the client's need to verify a 
large persistent disk cache;  one workaround would be to turn off 
persistent caches;  a longer-term solution would be to work with the 
folks on zodb-dev to land a set of improvements to the cache 
verification code (they live on a branch somewhere, I think).

All the cache verification speedups we had were released in ZODB 3.2
(see primarily "What's new in ZODB3 3.2 alpha 1" in

    http://zope.org/Products/ZODB3.2/NEWS

).  There aren't any more of those hiding on a branch.  There are
other kinds of optimizations hiding in assorted branches, though.

Having a "large" persistent ZEO cache has opposing effects: (a)
possibly better steady-state performance; (b) guaranteed longer
cold-start verification time.  That tradeoff is unavoidable with the
current design.  A possible future direction may be to use much larger
ZEO caches, but to weaken the meaning of "persistent" by simply giving
up after verification has consumed N seconds (throwing away all cached
objects that haven't managed to get verified by then).  There's no
code anywhere to do that now, though.

Subject: [Zope] changing the LDAP server address of an LDAPUserFolder
Message-ID: <BE0B0741.C614%s.morris@bangor.ac.uk>

A question about changing the LDAP server address of an LDAPUserFolder:

The address of our LDAP server has changed from ldap.mydomain.com to
ldap3.mydomain.com.

To accommodate the changes I tried the following:
Adding ldap3.mydomain.com LDAP Server under the configure tab and then
deleting the previous ldap.mydomain.com nearly works except users with
locally stored roles no longer can access the site.

Is it possible to change the LDAP server setting and retain the users with
locally stored roles? Or do I need to make a record of the users with
locally stored roles and add them again?


Zope 2.7.2
Python 2.3.4
LDAPUserFolder 2.4

There is nothing in the internal groups storage that keys off the 
server where the records came from. The association is made by the 
user's DN. Has the DN changed?

Subject: [Zope] uploading a file via an external method
Message-ID: <20050112131634.SM01144@CETSKL>

I've used this to upload files to a specific directory, not to Zope (or as
an Zope object). The problem is that it's looking in the folder for the
files and I'd like it to upload from a chosen directory (or my desktop) in
the same way as manage_addFile does. 

Kate


 
external method called upload_external:
 
import os, shutil
 
def upload_external(self,file,REQUEST):
 #check if file was sent correctly
 if file.read(1) == '':
  return '<h2>File does not exist</h2>'
 else:
  file.seek(0)
 iname=os.path.basename(file.filename)
 oname=os.path.join(self.savedir,iname)
 f=open(oname,"wb")
 f.write(file.read())
 # let's get the mime information
 mime_type=file.headers.headers[1]
 user=str(REQUEST.AUTHENTICATED_USER)
 try:
  self.add_entry(path=self.savedir,filename=iname,owner=user)
 except:
  os.remove(oname)
  return '<h2>File upload not completed correctly</h2>'
 return '''<h2>%s was sent correctly, and saved in %s</h2><h3>The Mime Type
of the file is</h3>%s<h3>Saved by</h3>%s''' % (iname,oname,mime_type,user)
 
 
The self.savedir is a property set in the folder which contains the external
method and tells the external method where to put the file.
 
The self.add_entry is an update on a database to keep track of the files
uploaded, etc.

One of the better ones, but centered on version 2.6.x, getting old.

The book is interesting because its focus is different than many other 
Zope books. It presents a style of Zope development that revolves 
around building Zope Products, and somewhat de-emphasizes Page 
Templates, Python Scripts and External Methods. It might be worth a try 
if you want to investigate extending Zope with custom Products.

I don't know of any other books that handle Zope Product development as 
extensively. Does anyone know of others that I could recommend?

mxm Proxy Tool

The mxmProxyTool is a Zope tool that fetches content from an external 
web source. The content can then be inserted in a page template or dtml 
page on your own site.

Generally speaking, it makes it possible to browse another website, 
inside the look and feel of your own.

It is thought of as a quick and dirty way to integrate external websites 
with a Zope site.

You can look at the "Undo" tab of the folder (or the root) which 
formerly contained the site object:  it might show the 
'manage_delObjects' call which removed the site, and allow you to undo 
that transaction (you may have to undo all subsequent transactions, as 
well).

The transaction / concurrency machinery of the ZODB makes such 
precautions normally unnecessary for persistent objects.  Are you 
needing to protect a non-persistent object, e.g. a module-level global 
data structure?  If so, Python's 'threading' module (or the lower-level 
'thread' module) is your friend.

See $ZOPE/lib/python/Products/StandardCacheManagers/RAMCacheManager.py 
for an example of such usage.

I'm using Apache as a frontend to zope/plone. 

Is it possible to configure Apache as follows : 

www.domain.ext  should all go to the filesystem (static html files) 
except www.domain.ext/plone should be handled by mod_rewrite 
  ( RewriteRule ^/(.*) 
http://localhost:7777/VirtualHostBase/http/www.domain.ext:80/VirtualHostRoot/$1

Any help appreciated.

Yes, and if you read the excellent documentation for Apache (because  
this question has nothing to do with Zope) at www.apache.org you can

Message-ID: <B04D245FBAA92241833B01C21BEC259E09E312FB@LMNFREX01>

Hi,

I have made 2 Zope products.

One of them is a content object that extends PropertyManager.
The  :
+ _update_property
+ _set_property
+ _del_property
methods have been redefined to add a call to my 2nd product, in order to
notify it about the changes.

--- code excerpt ---
def  _del_property(self,id):
 <call to the PropertyManager method>
 try:
  getToolByName(self,'change_tracker').manage_addChange(<params>)
 except:
  pass
-----

I created an object A of this type.

The 2nd product is a tool with a simple PersistentMapping() that store these
changes information.

--- code excerpt ---
def manage_addChange(self,<params>):
	...
	self._changes[<somekey>]=<somevalue> # self._changes is the
PersistentMapping
	self._changes=self._changes #to be sure PersistentMapping is updated
in ZODB
	...
-----

I created an object B of this type.

When I modify properties on A, I get the information added to B.
So I thought eveything was working fine.

Unfortunately, when I undo a change on A (using undo tab in ZMI),
information is not removed from B.

Can someone tell me what I did wrong ?

Thanks a lot.

Pascal

This should work (untested naturally):

RewriteRule ^/plone(.*) 
http://localhost:7777/VirtualHostBase/http/www.domain.ext:80/VirtualHostRoot/_vh_plone/$1 
[L,P]

But if your plone site is in a folder called plone, you should use:

RewriteRule ^/plone(.*) 
http://localhost:7777/VirtualHostBase/http/www.domain.ext:80/plone/VirtualHostRoot/_vh_plone/$1 
[L,P]

Is there any ongoing, current work on integrating Mailman with Zope? I

find any recent work or activity. I currently use Mailman for my mailing

Message-ID: <20050113181712.1389B2032D5@mail.zope.org>

My apache config required the use of the SiteRoot component.  I have an
apache web server w/SSL that I use for several things, and the zope/plone
site is available under https://hostname/plone

Using the Zope manage app, under my 'plone' site, I added a SiteRoot
component, and set its path to /plone.

In httpd.conf in the 443 virtual host area, I have:
RewriteEngine on
RewriteRule ^/plone(.*)
http://localhost:8080/plone/VirtualHostBase/https/hostname:443/plone/Virtual
HostRoot/$1 [P] 

If you don't need SSL, this would be:
RewriteEngine on
RewriteRule ^/plone(.*)
http://localhost:8080/plone/VirtualHostBase/http/hostname:80/plone/VirtualHo
stRoot/$1 [P] 
(note the two changes, https->http and 443->80)

Before I added the use of the SiteRoot, I could get the page, but all the
links inside the page were pointing to https://hostname and not
https://hostname/plone, and all images, stylesheets, etc were broken.  The
SiteRoot component rewrites all the links in the page, so that stylesheets,
images, etc. all show properly.

FYI, in case it helps, I use apache 2.0, Zope 2.7.3 and Plone 2.0.5.

Good luck,
Larry

Yes.  But what you want is much simpler.  To implement it, create a form
to capture the new user's name, then, as the action for that form, use the 
API (see the Appendices of The Zope Book and/or the code) to add a new
user.  The critical thing will be something like

	acl = container.restrictedTraverse( <<url of acl_users>> )
	acl.AddUser( name, password, roles, domains )

Not all user folders support adding users dynamically, but if you are
using the default, it does.  See the code for UserFolder to learn what the
defauts are for roles and domains.

Transactions are part of the ZODB and are documented
in the ZODB3 documentation (you can find an HTML and a PDF
version on "zope.org").

It is provided the product does not contain ZClasses.

The code for a ZClass is made available via a pseudo module
whose name is derived for the ZClass's class id. Therefore,
there can be no two ZClasses with the same class id.

Would you use a Unix flavour, I could tell you how you can
get some information. But, I know little about Windows...

Apparently, your Zope crashed. This usually happens in
an C extension (memory corruption, bad pointer, range overflow, ...).
Under Unix, I would attach Zope with a debugger and the
debugger would get activated when the fatal event occurs.

Maybe, Windows, too lets you run Zope in a C level debugger
that gets control in case of fatal events ?

If this is not enough to convince you, you might
add an additional persistent object between the session and the string.
I made the test with our own Transience implementation.
I introduces such an intermediate persistent object (holding the

When the change to A and B happens in the same transaction,
then the undo must revert both changes. If it does not, you
hit a bug.

Note that in older Zope versions, invalidation messages
were not sent correctly for "undo" (from ZEO).
This was fixed with ZODB 3.2.

Be careful!

There is a known bug when a ZClass inherits from a ZClass
defined in a different product.

Everything works fine as long as you do not export/import
the product. When you do, the inheritance gets broken.

Note, that what you do in the two cases is not the same!

  In the first case, you pass strings as arguments and get back a string.

  In the second case, you pass integers as arguments and get
  back an object (a "Shared.DC.ZRDB.Results.Results" instance).
  This must be converted to a string by the response object.

While it is surprising that the first case seems to be about an
order of magnitude faster, it might be explained (not sure!)
that the queries are different or the string conversion is
different.

I recommend to use a profiler to analyse precisely
where the time is used. A candidate would be ZopeProfiler:

Ok, I am using Zope 2.7.3, which includes ZODB 3.2.4

In the code below, I am not doing any transaction handling by myself.
When I modify A properties, the call to the B method (that modifies B
PersistentMapping) is made from the method of A that actually modidies A
pesistent data.

So why wouldn't A and B object changes be part of the same transaction ?
Is there any explicit code to make sure to remain in a single transaction ?

Thanks.

Hi,

I have made 2 Zope products.

One of them is a content object that extends PropertyManager.
The  :
+ _update_property
+ _set_property
+ _del_property
methods have been redefined to add a call to my 2nd product, in order to
notify it about the changes.

--- code excerpt ---
def  _del_property(self,id):
 <call to the PropertyManager method>
 try:
  getToolByName(self,'change_tracker').manage_addChange(<params>)
 except:
  pass
-----

I created an object A of this type.

The 2nd product is a tool with a simple PersistentMapping() that store these
changes information.

--- code excerpt ---
def manage_addChange(self,<params>):
	...
	self._changes[<somekey>]=<somevalue> # self._changes is the
PersistentMapping
	self._changes=self._changes #to be sure PersistentMapping is updated
in ZODB
	...
-----

I created an object B of this type.

When I modify properties on A, I get the information added to B.
So I thought eveything was working fine.

Unfortunately, when I undo a change on A (using undo tab in ZMI),
information is not removed from B.

Can someone tell me what I did wrong ?

Thanks a lot.

Pascal

One last thing I noticed :
Although when displaying B PersistentMapping content I can see A changes,
the undo tab of B says there is nothing to undo (while the undo tab of A
says I can undo whatever property change I did to it).

B class is declared as extending : UniqueObject, SimpleItem, Persistent

This question has been asked gazillions of times before.

If you search the mailing list you can find the answer.
If you search google using the key words 'zope format date' you will
notice in the results a link to zopelabs.  They have this great little

Subject: [Zope] Hierarchical content
Message-ID: <cs747k$era$1@sea.gmane.org>

I want to be able to create content and then attach sub-content to it. 
For example, if tasks were the content, it would look like the following:

go shopping
     get bananas
     get bread
pick up cleaning
     get shirt
     get pants
clean house
     clean kitchen
         clean mixer
         clean clean sink
     clean bedroom

I don't want to have the overhead of creating and sifting through 
folders as you navigate the hierarchy.  In order to do this, I need the 
ability to have content that has folderish properties allowing sub content.

Is there a product out there that has similar characteristics?  If I 
were to build this, what tools within plone would I use?

You could set a property on your item that points to the sub-items. 
If the list is ordered, you'd need to obviously also add some ordering
information.

Or subclass an existing document type and add the same type of thing.

It's possible the Firebird adapter sends the dates come back as strings..

try;

<dtml-var "ZopeTime(theDate).strftime('%F')">

otherwise I'm out of ideas for now d8)

Subject: [Zope] kinterbasdbDA Open Connection
Message-ID: <cs83be$pvd$1@sea.gmane.org>

Apologies if this has been answered previously - I have seen some similar
posts from years ago, but could not find any solutions.

I have defined a K Interbase Database Connection in my ZMI. Everything
appears fine until I attempt to open the connection using the "Status" page
in the ZMI. At this point, I get a standard "page not found" screen. This is
not a Zope error page, just a standard IE "HTTP 400 - Bad Request" page,
which of course gives me no useful information. It appears from the form on
the previous page that the page that is being called is
"manage_open_connection".

If I attempt to change connection properties using the "Properties" page,
then as long as "Connect Immediately" is not checked, then everything is ok,
and the changes are saved. If it is checked, then I get the same error page.
The page that is being called from here appears to be "manage_edit".

The Zope version is actually from a Plone 2.0.5 installation (this is not
taking place inside the Plone instance, hence posting here), Plone
Controller 0.3, Python 2.3.3 on win32.

I cannot find anthing including "manage_open_connection" in the kinterbase
folders, but from a previous post I guess it is aiming for the function in
"Plone\Zope\lib\python\Shared\DC\ZRDB\Connection.py". What I don't have any
idea about is why it isn't working, and what I can do about it.

Can anybody help?

Thanks in advance

No problem as long as you are using compatible versions of Zope on the
systems you are copying to/from (I would recommend using the same version of
Zope on all systems).

We do this all the time.

As long as both installation are installed in the same way there should be 
no problem.

You can even move it across operating systems (the FileStorage format
is platform-independent).

You take a small risk if you try to copy a Data.fs *while* it's in
active use, because it's in a temporarily non-sane state during the
time a transaction is being committed.  More here:

so is the new Data.fs.index regenerated when Zope is restarted?

ps - i've migrated Data.fs successfully and repeatedly between a netbsd 2.0
install a linux server with no issues. (and i didn't copy the .index file,
only the Data.fs)

If you copy over the .fs file but not the .index file too, then it's
best practice to delete the stale .index file (if any) on the
destination machine.  ZODB uses some heuristic checks to try to detect
a mismatching .index file, and they're pretty strong heuristics, but
it's possible they could fail to detect a mismatch.

It's always OK to delete an .index file.  ZODB creates an .index file
if none exists.  Leaving behind a stale .index file is a little risky.
 I expect it's much riskier to leave stale persistent ZEO cache files
in place, if the destination machine is being used as a ZEO server.

Subject: [Zope] Apache and Zope
Message-ID: <480ED19A579467459C9CCACFCD2135F7D3B7FA@utah.inside.msdinc.com>

This question may be more appropriate for the Apache mailing list, but it is Zope-related so I figured I'd check here as well.  I'm trying to set up Apache HTTP Server to run in front of three sites on my server.  Two of which are Zope sites and one of which is a PHP app that is hosted by Apache.  I've got three different URLs pointing to the IP address of the server.  The setup is something like this:

Zope Site 1 - Actual address: www.mysite.com:1234/zope1 Virtual Host: zope1.mysite.com (Zope is running on port 1234)
Zope Site 2 - Actual address: www.mysite.com:1234/zope2 Virtual Host: zope2.mysite.com
PHP Site - Actual address: www.mysite.com:7777 Virtual Host: php.mysite.com

Now here's the frustrating part - I've got it working perfectly as long as I'm accessing these sites from the server.  The problem is, whenever I try to access zope1.mysite.com or zope2.mysite.com from another machine, it sends me to php.mysite.com.  Any ideas? 

Here's my virtual host configuration:

NameVirtualHost zope1.mysite.com:80
<VirtualHost zope1.mysite.com:80>
   ServerName www.mysite.com
   RewriteEngine On
   RewriteRule ^/(.*) http://127.0.0.1:1234/VirtualHostBase/http/zope1.mysite.com/zope1/VirtualHostRoot/$1 [L,P]

Subject: [Zope] Memory and Large Zope Page Templates
Message-ID: <41E7E0FD.50200@earcon.com>

Hi all,

I'm trying to understand some questions about Zope and Memory 
management.   I've configured a Zope with minimal Cache settings: 100 
objects of cache, 4 threads and 20 Mb of ZEO Cache.   The Storage is a 
DirectoryStorage of 4Gb.   Monitoring the Zope process, all is running 
fine: it takes about 30 Mb of RAM.  I've see that just 2 of the threads 
are working.

The problem begins when I execute a report.  The report is a 
PageTemplateFile that calls a method to obtain a list of processed 
results and send them to the user.   It takes some time of process, but 
it works fine.   What I don't understand is why, after this report,  
Zope is taking 120 Mb of RAM !!  Too much for the cache I have. 

I've look for for a memory leak, showing refcounts in method like this:

    def _get_refcounts(self):
        import sys
        import types
        d = {}
        sys.modules
        # collect all classes
        for m in sys.modules.values():
            for sym in dir(m):
                o = getattr (m, sym)
                if type(o) is types.ClassType:
                    d[o] = sys.getrefcount(o)
        # sort by refcount
        pairs = map (lambda x: (x[1],x[0]), d.items())
        pairs.sort()
        pairs.reverse()
        return pairs

But there is nothing rare.   I can see how the refcounts of some objects 
are heavely incresed during the process of the report, but when finished 
they are freed.  But RAM of the Zope process don't decrease.  

Anybody have an explanation ?  It's recomended to run this kind of 
reports in a new process ?  In this case, there are any products to help 
this way ?

Thanks in advance

It should be part of the latest 2.7 release. 2.7.0 is old and buggy.
I assume it is in the "utilities" directory.

If you look at Zope-dev, there have been some discussion regarding leaks 
and memory management.

IIRC, I think that once the size of your process increases, it won't 
shrink... however, this does not mean that it will not reuse the same 
memory again...

I mean, if you experience the following, it should be normal:

initial size of Zope -> 30 MB
you run the report: new size -> 150 MB
after a while, you run again the report: new size: 150 MB

if you run again the report, and you end up with a size of 270 MB (150 + 
120) this is a problem.

Dou you know if this is a python behaviour ?  Or a generic one in 
process managements ?

Yes, that's the situation when the report is executed by the same 
thread.  But If some reports are executed at the same time in different 
threads, then the memory size is increased again,  aprox to  30Mb + 80Mb 
* simultaneous_threads

When you change A and B in the same request and you do not
explicitly manage transactions yourself, then both changes
are in the same transaction.

Or said differently: Zope (by default) has one transaction per request.

The UNIX memory API allows to grow and shrink the heap only at one end.
If there is a block (as tiny as it may be) at this end, then
it prevents to give back any unused memory to the OS before that block.
Usually, there is no way to compact the memory (as it is accessed
directly and not via an indirection).
Therefore, you rarely see that the memory allocated to a process
decreases.

The "Undo" tab at an object does not (!) list all transactions
having affected this object!

Instead, transactions can have a description.
Zope usually puts the path of the object located by URL traversal
into the description field.
The undoable transactions listed at object "O"s "Undo" tab
are the transactions that have "O"s path as prefix of the transaction's
description.

Thus, usually, there is only a slight chance that you
see a transaction record for "T" in "O"'s "Undo" tab even when
"T" modified "O".

Subject: [Zope] Complex SQL query
Message-ID: <BAY24-F1409CB138DAE4365B2F327AA8B0@phx.gbl>

Hit here.

I'v 2 databases (GadFly) that have different data.
I wish to join some data using a ZSQL method.

I have something like:

SELECT table1.colum1, table2.colum1
FROM table1, table2
WHERE table1.colum1 = table2.colum1

Until this step everything is working fine...
The problem appears when I want to compare the result of the above query 
(taht is working ok) with some data that only exists in the table2 and in 
table1.

I want to get some data from the table1 that I compare in table2 
(table1.colum1 = table2.colum1) and them I only want the data that the in 
the table1.colum1 is equal to 1 and 2 and in the table2 where above 0 (zero) 
in the colum2 and the colum3 < than the actual date.

I try to put something like:

SELECT table1.colum1, table2.colum1
FROM table1, table2
WHERE table1.colum1 = table2.colum1 AND table2.colum2 > 0 AND table2.colum3 
< <dtml-var expr="_.float(_.DateTime())"> AND table1.colum1 = 1 OR 
table1.colum1 = 2

This query is getting ZOPE to time out and it only works again with a 
restart...

Can anyone help me with this?

Thanks a lot,

  José Monte

P.S. - sorry for my extremely bad english.

Have you considered switching to a *real* database? Gadfly is not 
recommended for anything beyond playing. Try PostGreSQL or MySQL 
instead.

Don't. Try FrontBase instead:

http://www.frontbase.com/

Not open source, but they have a free license (E-Starter).

Runs pretty much everywhere as well.

Just had too much pain and suffering dealing with all those odd

FrontBase is a no-brainer to use and, as an added bonus, is fully SQL

You didn't SELECT table2.colum2 or table2.column3 so it probably doesn't
exist for your comparison.  I don't know if the DateTime may be giving
any problem.

Subject: [Zope] generating an acquisition wrapper from generated code
Message-ID: <20050115032637.GA20812@mail.imagesmiths.com>

Hi all,

====Aclass.py====
class Aclass(ZSI.TCcompound.Struct):
   def __init__:
     self._attr = "Attribute"
   def getAttr():
     return self.attr

====myTool.py====
from Aclass import Aclass
from Globals import InitializeClass
from OFS.SimpleItem import SimpleItem
from AccessControl import ClassSecurityInfo
from Products.CMFCore.utils import getToolByName, UniqueObject
from Products.CMFCore import CMFCorePermissions

class myTool(SimpleTool,UniqueObject):
  meta_type="myTool"
  id="myTool"
  def getAclass(self):
    inter = [base.Aclass(),]
    return inter

Now I want to myTool.getAclass().getAttr()
What's by importing myTool from unrestricted python, there's no problem.

When I access the tool from a (restricted) script or ZPT, it gives me:
   Insufficient Privileges
   or
   AccessControl.unauthorized.Unauthorized: You are not allowed to access 'getAttr' in this context.

I gather (thanks kosh@freenode#zope) that I need to wrap the objects in inter in an acquisition wrapper. But I can't inherit from SimpleItem as well as ZSI.TCcompound.Struct:

File "/usr/lib/python2.3/site-packages/ZSI/TCcompound.py", line 65, in __init__
    raise TypeError('pyclass must be None or a class, not <extension class ExtensionClass at f6b..>

Any Suggestions?

Thanks... And sorry for my bad python.  This pseudocode should be an accurate representation of what I get from ZSI's wsdl2py from Amazon's Web Services 3.0 WSDL.  Complex stuff, so try to not suggest something that would require I change Aclass -- been down that road already.

Aclass needs to be inherited from Acquisition.Explcitit or Implicit
and and in myTool:

def getAclass(self):
      inter = [base.Aclass().__of__(self),]
      return inter



hope this helps

maybe you need to add security declarations to your class

Subject: [Zope] Python 2.3.3 vs. Python 2.3.4
Message-ID: <41E98E58.17931.BB5653F@localhost>

Hi. I am unclear of the benefits of using Python 2.3.4 over Python 
2.3.3

Could someone please explain? The reason being is that I am having 
trouble upgrading my Fedora Core 1 server getting the 2.3.4 rpm to 
install:

rpm -ivh python2.3-2.3.4-3pydotorg.i386.rpm

Results in many errors and will not install.  This is the same method 
I used to upgrade the Python version alongside the existing FC1 
python.

I have installed and run Zope 2.7.3 for about two months now along 
with Python 2.3.3, with no problems that I am aware of (which does 
not mean that there are none).

I have now installed Zope 2.7.4, still with Python 2.3.3, and Zope 
and Plone 2.0.5 both appear to behave normally.

Am I alright continuing to run Python 2.3.3?  Or is disaster lurking 
by not running Python 2.3.4?

TIA

As the version number says: 2.3.4 fixes bugs present in 2.3.3 and earlier.
Python 2.3.3 has no *critical bugs* so we did *not* recommend to upgrade

> Hi. I am unclear of the benefits of using Python 2.3.4 over Python
> 2.3.3

A micro release of Python is a bugfix release.  Here are the NEWS
entries for 2.3.4; whether you care about any of 'em is up to you:

Core and builtins
-----------------

- Bug #858016: isinstance() and issubclass() can have their second
  argument be a tuple whose nested depth is capped at the interpreter's
  recursion limit.  Raises RuntimeError if the limit reached.

- Made omitted callback and None equivalent for weakref.ref() and
  weakref.proxy(); the None case wasn't handled correctly in all
  cases.

- Fixed problem where PyWeakref_NewRef() and PyWeakref_NewProxy()
  assumed that initial existing entries in an object's weakref list
  would not be removed while allocating a new weakref object.  Since
  GC could be invoked at that time, however, that assumption was
  invalid.  In a truly obscure case of GC being triggered during
  creation for a new weakref object for an referent which already
  has a weakref without a callback which is only referenced from
  cyclic trash, a memory error can occur.  This consistently created a
  segfault in a debug build, but provided less predictable behavior in
  a release build.

- Fixed a bug in object.__reduce_ex__ when using protocol 2.  Failure
  to clear the error when attempts to get the __getstate__ attribute
  fail caused intermittent errors and odd behavior.

- fixed: if a file is opened with an explicit buffer size >= 1, repeated
  close() calls would attempt to free() the buffer already free()ed on
  the first call.

Library
-------

- Bug #876278: Unbounded recursion in modulefinder

- Brought platform.py in line with the 2.4 version, fixing support for
  newer Windows versions and a cache issue.

- Bug #950057: itertools.chain() and itertools.cycle() now handle
               exceptions immediately instead of waiting until the
               input source is updated.

- Bug #931848: Fix _sre.CODESIZE on 64-bit machines in UCS-4 mode.

- Bug #938076: Consider output encoding in XMLGenerator.

- Bug #936637: Properly delegate startElementNS in saxutils.XMLFilterBase.

- Bug #944082: Empty passwords in urllib2 are now supported.

- Bug #926075: Fixed a bug that returns a wrong pattern object
  for a string or unicode object in sre.compile() when a different
  type pattern with the same value exists.

- Bug #924361: Properly support normalization of empty unicode strings.

- Fixed a caching bug in platform.platform() where the argument of 'terse' was
  not taken into consideration when caching value.

- Bug #920575: A problem that _locale module segfaults on
  nl_langinfo(ERA) caused by GNU libc's illegal NULL return is fixed.

- Bug #883604: Fix Lib/test/test_strftime.py to escape characters from locale
  time values that might be mistaken as regex syntax.

- Bug #700055: .pth files can now have any type of line endings.

- Patch 817379: Allow absolute ftp paths in urllib2.

- Patch 711838: Support non-anonymous ftp URLs in urllib2.

Windows
-------

- The Windows installer now includes tix, the Tk Interface eXtension,
  a powerful set of user  interface components that expands the capabilities
  of your Tcl/Tk and Python applications.

Build
-----

- Bug #929689: Don't define _XOPEN_SOURCE on UnixWare 7.1.4.

Apart from the specific upgrade problems, if you're setting up a 
production-quality site it is *plain bad* to use *any* Python provided 
by the distribution. Build your own to retain the control you need to 
guarantee your site's well-being.

If you just want to play around I suppose you're fine.

You've got the syntax completely wrong for name based virtual hosts,
you've done it for IP based virtual hosts, in which case the last
definition of the vhost for the ip address takes effect.

> NameVirtualHost zope1.mysite.com:80

The NameVirtualHost directive specifies the IP address Apache runs the
name based virtual host check on. On a host with only one IP address,
or multiple that should point to the same site, it goes like this:
NameVirtualHost *:80

> <VirtualHost zope1.mysite.com:80> 
>    ServerName www.mysite.com 
>    RewriteEngine On 
>    RewriteRule ^/(.*)
> http://127.0.0.1:1234/VirtualHostBase/http/zope1.mysite.com/zope1/VirtualHostRoot/$1
> [L,P] 
> </VirtualHost> 

The value in the VirtualHost 'tag' is the _IP ADDRESS_ that the
virtual host runs on, not the server name. This config will work:

NameVirtualHost *:80

<VirtualHost *:80> 
   ServerName www.mysite.com 
   RewriteEngine On 
   RewriteRule ^/(.*)
http://127.0.0.1:1234/VirtualHostBase/http/zope1.mysite.com/zope1/VirtualHostRoot/
$1 [L,P]
</VirtualHost> 

<VirtualHost *:80> 
   ServerName www.mysite.com 
   RewriteEngine On 
   RewriteRule ^/(.*)
http://127.0.0.1:1234/VirtualHostBase/http/zope2.mysite.com/zope2/VirtualHostRoot/$1
[L,P]
</VirtualHost>

<VirtualHost *:80> 
   ServerName www.mysite.com 
   RewriteEngine On 
   RewriteRule ^/(.*) http://127.0.0.1:7777/$1 [L,P] 
</VirtualHost>

I can post more code if necessary, but:

this is a extension class problem

try to get the __init__ of the superclass via __dict__

instead of:

ZSI.TCcompound.Array.__init__(self,...)

use:

ZSI.TCcompound.Array.__dict__['__init__'](self,...)

Yes there are some errors, but...

Not if he wants to do name-based virtual hosts and thats probably what
he wants, as the following doesn't make any sense at all...

This doesn't make any sense and even though I'm not a apache-pro I
don't think its correct at all. How does apache decide which
VirtualHost to use?

For the OP, if you use only the following NameVirtualHost and leave
the rest as is, it should work:

NameVirtualHost *:80

        filled) will be used for calculations in the reports.<br>
        Please make sure that you check that the client do not exist in the

------------------------

and this script:
--------------------
##parameters=REQUEST
##title=
##
# parse input from "addclient" form and returns the result.

req = REQUEST

# if no name was specified
if not req.customer:
    return container.addclient(error_message = "You must specify the customer's name")

context.add_client(name = req.customer, onsite = req.onsite,
                     remote = req.remote, phone = req.phone)

response = container.clientsubmited(name = customer)
return response
----------------------

in case of an error, it re-renders the template with the error above. this 
works fine, but I want it to keep the values already entered in the form, 
not to give me a blank form. one way to specify them when calling the
template from the script, but in large forms this will result in a very
long parameter list. is there one object that holds all the values that I
can pass back to the template?

Subject: [Zope] ZODB packaging behaviour: bug or feature?
Message-ID: <BAY102-DAV10C770A39B7F55DE0EDD1EFF8D0@phx.gbl>

Use case:  
Create a new Zope instance. Perform some changes and then pack the database to remove objects revisions older to 0 days. You want a clean instance to start with.
Now create a cron job to daily pack the database to remove objects older to 14 days, and start to use your instance. Zope won't pack the database at all, and I guess it will be for the first 2 weeks, because it won't find revisions older to 14 days during that time.

Is that normal behaviour? Telling by the interface text at the Database Management tab, it looks like the command would create a Data.fs.old file even though there weren't older revisions than the number set, meaning that by default the packing would create an exact copy of the current Data.fs (to keep all changes), at least until there were revisions to remove. The problem is that if you rely on Data.fs.old for backup purposes, you'll find that your 13th day Data.fs.old is exactly as that of day one.

An even though you had never packed the database to 0 days, the problem would come up if, for any reason, you feel like it's time to manually pack the database to 0, in between those two weeks. Your cron job won't modify the existing Data.fs.old for the following two weeks.

Am I missing something? Thanks in advance,

when I try to add an editable property sheet interface
for a propertysheet with a multiple selection property,
this runs into the error shown below:

Traceback (innermost last):
  Module ZPublisher.Publish, line 101, in publish
  Module ZPublisher.mapply, line 88, in mapply
  Module ZPublisher.Publish, line 39, in call_object
  Module ZClasses.Property, line 84, in manage_createView
  Module ZClasses.Property, line 188, in manage_createEditor
  Module ZClasses.Method, line 103, in manage_addDTMLMethod
  Module OFS.DTMLMethod, line 403, in addDTMLMethod
AttributeError: 'unicode' object has no attribute 'read'

Does anybody have suggestions?

Regards
Thomas

P.S.:
I'm currently working on (Zope 2.7.3-0, python 2.3.4, win32) under
Windows XP with Python 2.3.4 (#53, May 25 2004, 21:17:02) [MSC v.1200 32 bit 
(Intel)]

Subject: [Zope] ZODB packaging behaviour: bug or feature?
Message-ID: <BAY102-DAV13CC19F5EC0FFF8EA10EB5FF8D0@phx.gbl>

(sorry about the HTML encoding of my previous post)

Use case:
Create a new Zope instance. Perform some changes and then pack the database
to remove objects revisions older to 0 days. You want a clean instance to
start with.
Now create a cron job to daily pack the database to remove objects older to
14 days, and start to use your instance. Zope won't pack the database at
all, and I guess it will be for the first 2 weeks, because it won't find
revisions older to 14 days during that time.

Is that normal behaviour? Telling by the interface text at the Database
Management tab, it looks like the command would create a Data.fs.old file
even though there weren't older revisions than the number set, meaning that
by default the packing would create an exact copy of the current Data.fs (to
keep all changes), at least until there were revisions to remove. The
problem is that if you rely on Data.fs.old for backup purposes, you'll find
that your 13th day Data.fs.old is exactly as that of day one.

An even though you had never packed the database to 0 days, the problem
would come up if, for any reason, you feel like it's time to manually pack
the database to 0, in between those two weeks. Your cron job won't modify
the existing Data.fs.old for the following two weeks.

Am I missing something? Thanks in advance,

Subject: [Zope] redirect to a https server sending post parameters
Message-ID: <200501161804.j0GI4CY1015609@dell01.dinaserver.com>

Hi to everyone,

I'm building an e-commerce website using zope and I've come to a problem I
don't know how to solve.

I'm trying to make a redirect to the bank server from a python external
method but the page which I'm trying to redirect only accepts parameters
sent using a post method.
Doing a little of research I've found out a very close solution at
http://mail.zope.org/pipermail/zope/2003-March/132569.html using M2Crypto
and urllib.
The problem is I need to do a redirect insted of returning the bank's page
as if I was serving it.

Does anyone know how to do this? Any help would be greatly appreciated as
I'm really stuck.

Thanks a lot in advance,
Toni.

I don't know what "normal" means, but it's the behavior you're asking
for in that scenario.

If you're using a current ZODB (anything at or after 3.2.1c1; 3.2.5 is
the latest stable release in the 3.2 line), an attempt to pack to a
time earlier than the most recent time ever packed to shouldn't do
anything more than raise a FileStorageError with this detail:

    The database has already been packed to a later time
    or no changes have been made since the last pack

Sorry, that's not a reasonable backup strategy.  The intended way to
do FileStorage backup is explained here:

Which is one reason for doing backups the intended way <wink>.

Manually packing the database to 0 is a novel meaning for "never
packed the database to 0 days" <wink>.

You're missing that regular backups are needed regardless of packing
-- tying backups to packing is poor practice.  The intended backup
procedure is independent of when pack does or doesn't happen to get
rid of something.  In fact, it goes faster if packing doesn't occur
(so long as that's true, it can do quick incremental backups instead
of a full backup -- read the page referenced above).

It matches the Host: header against the ServerName attribute. See
http://httpd.apache.org/docs-2.0/vhosts/name-based.html, it's the same
for 1.3 as well.

That will work as well, but only because the separate hostnames point
to the same IP address. The attribute in the VirtualHost 'tag'
specifies the IP address to bind the virtual host definition to, in
the case of name-based you just assign the same IP to all the hosts on
that IP address.

The request details are in the request/form/itemname TALES expression,
so just put tal:attributes="value request/form/itemname | nothing" in
the tag. I can't tell you offhand how to check the values for things
like checkboxes, but I think it should be tal:attributes="checked
python:REQUEST.form['itemname'] == itemvalue", but I may be wrong.

thanx, after playing a little with formulator, I found how to do that, but
it's always good to have another option :)

Your problem description is somewhat weird. Redirection means that you use 
RESPONSE.redirect()
which will generate a HTTP Location: header. So what do you need? A 
redirection or resubmission
of the data to some other URL?

perhaps an rpm -Uvh rather than an rom -ivh is a better idea when upgrading?

also try uising the built in tools for upgrading ... these are usually
specific to your distribution .. mandrake have urpmi, suse have yast and
redhat have something else?

Subject: [Zope] Python 2.3.3 vs. Python 2.3.4


Hi. I am unclear of the benefits of using Python 2.3.4 over Python 
2.3.3

Could someone please explain? The reason being is that I am having 
trouble upgrading my Fedora Core 1 server getting the 2.3.4 rpm to 
install:

rpm -ivh python2.3-2.3.4-3pydotorg.i386.rpm

Results in many errors and will not install.  This is the same method 
I used to upgrade the Python version alongside the existing FC1 
python.

I have installed and run Zope 2.7.3 for about two months now along 
with Python 2.3.3, with no problems that I am aware of (which does 
not mean that there are none).

I have now installed Zope 2.7.4, still with Python 2.3.3, and Zope 
and Plone 2.0.5 both appear to behave normally.

Am I alright continuing to run Python 2.3.3?  Or is disaster lurking 
by not running Python 2.3.4?

TIA

Greg,

A nifty way to create a folderish hierarchy is by
using the TopicIndex class of the DocumentLibrary
product. You simply import a tabbed-indented outline
such as that found here:
http://zope.org/Members/Kaivo/DocumentLibrary/1.0/LegalTopicIndex.txt

You can even leave out the numeric ids in the sample;
sequential ids will be assigned automatically.

HTH,

Ken

I am literally terrified of overwriting the Fedora Core 1 System 
python in this manner (this is a production system).  If I did that, 
FC1 would be trashed, as lots relys on the older version of Python.  
I have no way to judge if what you suggest is safe of not, except 
some vague Q&A's at python.org that might suggest that it is.  My 
understanding is that -ivh will install alongside previous versions 
as opposed to upgrading them, and thus is a safer option.

>> Build python
This is maybe what I should do.  Can and one provide definitive 
insight into how to do this alongside the existing FC1 python. The 
two python versions must be completely separate, or the system is 
toast.

I'm guessing something along the lines of:

cd python2.4
configure --prefix=/where/should/I/put/python?
make
make install

Per above, I need help with the prefix-- what should the path to the 
new python be? There shold be no chance of overwriting the system 
python.

Thanks!

If you take a look at the Python sources from python.org or simply run 
./configure --help it will tell you all those details. There is no 
rocket science involved.

By default, if no separate --prefix option is specified, everything 
will go under /usr/local, so there is no clash whatsoever.

BTW, *nobody* suggested using Pythhon 2.4;  the suggestion was to use 
Python 2.3.4, which contained at least one known "stability / crash fix" 
exercised by Zope.

Try '/opt/zope', or some such.  It really doesn't matter, as long as it 
isn't '/usr' (which is where FC puts the "stock" Python).  If you pass 
no prefix at all, Python's 'configure' will assume '/usr/local', which 
would work, too.

I suggest that you check where the default python is installed with
commands like `whereis python`.
Most likely it will be in /usr/bin/python.
If that is the case, you could install the up-to-date version in 
/usr/local. Otherwise any directory that you have write permission
will suffice.

2.4 or 2.3.4 (in the title)! Pay attention to version numbers.

You can also rename the python binaries to python2.4 (post-install)
to avoid confusion amongst the maitenance team.

Sorry-- Python 2.3.4 is what I meant.  But this question would really 
apply to any version of python to be installed that applies to the 
system python.

Thanks for the suggestions-- I do believe that I now know how to 
install multiple versions of python on one machine. I will test on a 
development machine prior to deployment on production.

What about "manage_menu"? This is the left frame in Zope's Management Page

HTTP 1.1 explicitely forbids HTTP compatible clients to
redirect a POST request without explicit interaction
with the user.

Current browsers do not support a redirected POST at all.

Thus, you proably do not want to use "redirect".

Instead, you could use "urllib2" (maybe "ZPublisher.Client")
to send your "POST" and return back the result to your client.
Your application behaves in this case as a proxy.

I see no chance for you.

Why do you need a redirect? Why can you not behave as a proxy?

This traceback does not correspond to your subject:

  The traceback tells you that you try to create
  a "DTMLMethod" from a "unicode" string.

  However, "DTMLMethod" only supports normal (non unicode) strings
  or file like objects.

Check, where the string comes from that you want to convert
into a "DTMLMethod". Ensure, it is a simple string and not unicode.

and it is new since Zope2.7b4.

It is happening with a few products like SimpleURL and KnowledgeKit and 
I am getting errors like:

"Unauthorized: You are not allowed to access 'blah' in this context"

It could be a method, a list or ZopeTime.

I looked over the release files and can't find anything on this

There were no ZClasses changes since ages (in fact there is nobody willing

There was a change in 2.7.3 that broke a few people's permissions structures. 
The discussion about that kinda petered off with no real resolution, so the 
change is still active in 2.7.4.

Sorry, no handy reference at the moment. The change was in 
AccessControl/ImplPython.py function guarded_getattr. The following change 
"fixed" it for me, though there is concern about the validity of the change:

***************
*** 551,560 ****
              return v

          validate = SecurityManagement.getSecurityManager().validate
+         # Filter out the objects we can't access.
+         if hasattr(inst, 'aq_acquire'):
+             return inst.aq_acquire(name, aq_validate, validate)
+         # Or just try to get the attribute directly.
          if validate(inst, inst, name, v):
              return v
      raise Unauthorized, name

Ok. This seems to have worked for me on Fedora Core 1, where there is 
a risk of hosing your system python if you do not do this right.

I chose to build a clean verion of Python 2.3.4 and run it alongside 
other Python versions that were on the system.

Get Python from www.python.org 
Put the tarball somewhere, like: /home/myhome/src/python/2.34
su to root
cd /home/myhome/src/python/2.34
gunzip version_of_python.tgz
tar -xvf version_of_python.tar
cd version_of_python
./configure --prefix=/opt/python2.3.4
make
make install
ln -s /opt/python.2.3.4/bin/python2.3 /usr/bin/python2.3.4
cd /usr/bin
chmod 755 python2.3.4

To test, type: python2.3.4
You should get a version listing of 2.3.4 and the Python console. 
Ctrl-D to exit.

Then modify zopectl and runzope in /etc/zope-instance/bin to point to 
 the new path to Python 2.3.4. Back these files up before making 
changes.

Restart Zope, hopefully without any problems:

service zopectl restart (assuming you have created such a service)

If Zope will not start, you can always revert the paths in zopectl 
and runzope to the old python, whatever that was.

Again, be very careful on Redhat / Fedora systems that rely on Python 
for critical services... I would hate to hear that someone overwrote 
their system Python!

Good luck to the next vict... er... I mean... lucky person who trys 
this.

Hi all
I create a product. It have a method like this:

def Render(self, args):

    return self.getId()

In these folderish product I put some folders and some objects inside them

I would like to execute something like:

object.Render(args)

where:
object is an object inside a folder inside my product
Render is the product's Render method acquired by the object

the response is the id of my product instead the id of the object as 
expected

Is this possible? How?

Thanks a lot!

Subject: [Zope] Bad performances with ordered folders
Message-ID: <1106036008.22583.26.camel@m22241.6220.onf.fr>


  Hi,

I use Zope (2.6.1) and subclasses of the "old" OrderedFolder product
(release 0.4) to handle my internal site.

Each "sub-site" is a kind of "big folder", handled by a specific
"sub-manager", containing until two levels of sub-folders. Each folder
or sub-folder is a subclass of OrderedObjectManager, containing
documents (stored as ExternalFile subclasses) as well as other instances
of custom properties.
I have an "index_html" method (in DTML) defined for each folder or
sub-folder, which displays the ordered hierarchy of the given folders or
sub-folders ; access is checked against every sub-folder, so that
"private" folders or sub-folders are not displayed to unauthorized
users.

Data handling is OK, but while displaying my other custom classes
instances is quite quick, displaying these OrderedObjectManager
instances is quite slow, even when a sub-site is containing only a few
number of folders or sub-folders.

I've tried to use a profiler to find a bottleneck, but don't know Zope
and Python internals very well so handling this problem is not very
easy.
Any help or advise would be very helpful.

Thanks,
Thierry

There is a report of what I believe is the same issue here:

Feel free to add the ZClass problem to the Zope collector though.

I finally managed to come up with unit tests for this and am going to 
check them into Zope RSN.

To be safe, you should rebuild the Zope extension modules after 
upgrading to the new Python:

   $ cd /path/to/Zope/src/
   $ configure --with-python=/opt/python2.3.4/bin/python # + other args
   $ make
   $ sudo make install

This isn't really risky -- you have to try pretty hard to step on the 
system python.  If you grant yourself write access on the target 
directory, you can even forego running Python's 'make install' as root, 
which makes it effectively impossible to screw up the system python.

Subject: [Zope] HOWTO add a new Python alongside an old
Message-ID: <41ECCA60.31374.331DD54@localhost>

After some excellent suggestions, here is one way to add a new Python 
version alongside an old one (as one might need to do in the Fedora 
environment when upgrading Zope.) 

I chose to build a clean version of Python 2.3.4 and run it alongside 
other Python versions that were on the system (2.3.3)

-- Get the version of Python you need from www.python.org (Check 
Zope/Plone dependancies)
-- Put the tarball somewhere, like: /home/myhome/src/python/2.34
-- su to root
$ cd /home/myhome/src/python/2.34
$ gunzip version_of_python.tgz
$ tar -xvf version_of_python.tar
$ cd version_of_python
$ ./configure --prefix=/opt/python2.3.4 (Assuming that's where you 
want to put it. /usr/local could be used as well.)
$ make
$ make install
$ ln -s /opt/python.2.3.4/bin/python2.3 /usr/bin/python2.3.4
$ cd /usr/bin
$ chmod 755 python2.3.4

-- Test: 
$ python2.3.4
You should get a version listing of 2.3.4. Ctrl-D to exit.

To be safe, you should rebuild the Zope extension modules after 
upgrading to the new Python:

$ cd /path/to/Zope/src/
$ configure --prefix=/path/to/ZopeInstallation --with-
python=/opt/python2.3.4/bin/python # + other args 
$ make 
$ make install

-- Then modify zopectl and runzope in /etc/zope-instance/bin to the 
new path to Python 2.3.4. Back these up before making changes.

-- Restart Zope:
$ service zopectl restart (assuming you have created such a service)

Hopefully, Zope will start.

Any chance of Windows builds appearing for MySQLdb-1.0.1 and ZMySQLDA 
2.0.9b2?

Also, could 2.0.9b2 become 2.0.9? l0(

Remove the 'client' key from the storage config in zope.conf.

$ZOPE_HOME/lib/python/ZODB/component.xml says,

     <key name="client">
       <description>
         Enables persistent cache files.  The string passed here is
         used to construct the cache filenames.  If it is not
         specified, the client creates a temporary cache that will
         only be used by the current object.

     </key>

The corect way to solve this is to change, for example, your non-ssl 
example would become...

http://localhost:8080/plone/VirtualHostBase/http/hostname:80/VirtualHostRoot/_vh_plone$1

Sure, there's a chance. There's a zero chance of me building them,
since I have neither the tools nor the inclination, but a non-zero
chance of someone else building them, and if they let me know about
it, I'll make it available for download on SourceForge.

Just scratch out the "b2" and you'll be fine. I'm working on some
small issues for MySQLdb-1.1.9, which wlil almost certainly become
1.2.0, and then maybe I can think about ZMySQLDA.

Yep, if you have MSVC++ installed, you should get a modal dialogue box 
pop up when Zope crashes.

However, I would stress that using runzope.bat in a command prompt is 
much more fruitful and finding out what kills things than usign Zope as 
a service.

Hopefully the work Mark Hammond is doing on this will make things better 
eventually...

What overhead is this?

I'd do this as nested ordered folders and use the ZMI to manage it all, 
unless there are other hidden requirements here...

No, at least not with acquisition:

  When you acquire a method, you change its "self".

  This is necessary because the "self" of a method must
  be an instance of the class defining the method.
  The acquiring object usually does fulfill this requirement.

>How?

There are several ways:

 * you use an ExternalMethod or PythonScript for "Render"
   rather than a standard method definition

 * you make "Render" an object with a "__call__" method.
   In its "__call__" it can access the acquisition context
   (your "object" above) with "self.aq_parent".
   The product instance can be accessed with "self.aq_inner.aq_parent".

   That this works, the "Render" object's class must inherit
   from "Acquisition.[Im|Ex]plicit" and your product class
   must inherit at least from "ExtensionClass.Base" (better
   "Acquisition.[Im|Ex]plicit").

   Note that the option above is a specialization of this one
   (where you use predefined object classes with the required
   features).

 * You "reuse" the "Render" method of your product class
   in your object via:

      class MyObject(...):
        Render = MyProduct.Render.im_func

I'm going to stick my neck out and disagree with Dieter, I remember this 
being an artefact of the python memory manager...

That sounds odd, although not really. Each thread keeps its own ZODB 
object cache. This cache has a target size which is vaguely tunable, but 
if a singly transaction loads lots of objects (as your report likely 
does) they will all end up being loaded regardless of your cache 
setting. The trick is not to load so many objects into memory (see low 
level ZODB methods for synching, subtransactions, etc) or to make the 
objects more lightweight (see ZCatalogs and brains in particular)

I'm sure I remember discussions where it was agreed that this annoying

(or at least turned into a subclass that could be easily caught, rather

What's the python you're using to obtain 'object'?

The overhead the user has to incur to create subtasks.

If folders are used to create the hierarchy, the user must first create 
a folder to hold the subtasks for "Pick up cleaning" and then enter the 
two subtasks.  I'd rather just directly create a subtask because that 
eliminates the step to create a folder.

Viewing will also be cleaner because you never the a folder obscuring 
the subtasks.

It was changed (to log a message instead).  I see that it's in ZODB
3.3 (under svn), but not on the Zope-2_7-branch branch of ZODB3 (under
CVS).  Don't know what happened there.  Looks like we're missing
several changes that were checked in -- maybe they're only on ZODB3
HEAD?  Something's screwed up here indeed.

Hi All,

It's a long time overdue, but here's the roundup. I suspect these all 
made it into 2.7.4, if anyone's curious :-) The great news is that lots 
of bugs were resolved, and it was especially good to see patches 
contributed by people outside the usual core of developers. Thanks to 
those people!

The next bug day is going to be on Thursday 27th November as an 
experiment to see if those who complain about the Friday bug days can 
make it. Hope to see all on #zope-dev next Thursday!

cheers,

Chris

After more staring, same story:  the changes are in ZODB 3.3 (used
with Zope 2.8 and Zope 3), but not on CVS's Zope-2_7-branch branch of
ZODB3.  I don't intend to address anything other than critical
bugfixes in the ZODB 3.2 line anymore, so I don't intend to change
this.  If someone else wants to merge in this specific change on
Zope-2_7-branch, that would be OK by me.

I'm also not clear about what you want to do. Are you talking about 
creating content or viewing it? Or both?

I *think* what you are talking about is what is called 'mixed content 
elements' in XML: an element can contain both text and other elements.

If so, this is handled seamlessly in xml/sgml editors (Epic, FrameMaker, 
maybe Openoffice) and tools associated with them for creating web 
content, but there are no straightforward ways of dealing with this in 
Zope. Plone's default folders (still folders) are mixed-content 
elements. The Archetypes product for CMF/Plone works, but is 
ridiculously complex and buggy. The Silva content management framework 
may be what you want, but you have to want what Silva delivers. 
XMLparser is a proof of concept, not a usable tool.

To deal with this type of content effectively you may need to look 
elsewhere - check out the Apache Lenya and Forrest projects for example, 
or the tools building up around IBM's DITA. Or you'll need a Zope expert 
(Chris, for example) to build it for you to meet your particular needs.

In theory, Zope should be great for creating task-focused online 
documents. In practice it can be great at rendering them, but there are 
no useful open-source tools to move content from productive 
authoring/editing environments (Epic/FrameMaker with docBook or DITA XML 
schemas/DTDs) into the Zope 'publishing' environment.

Unless you guys know different...

Thanks for your answer.

Yes, I understant how ZODB cache works with threads.   The behaviour I 
didn't understood is why, once transaction is finished, the ZODB Cache 
decrese in number of objects but the RAM process not.

I'm already using brains.  I've tried your suggestion of 
subtransactions, but there is no change (I think it's normal, I'm not 
changing any persistent object).  I'm not sure how a _p_jar.sync() can 
improve something.

I think that the best solution will be run the report in a new process, 
spawning a ZEO Client to do the work and waiting for it.

How does a folder obscure the subtask?

This is the pythonic behaviour I was talking about.
If you want it fixed, bug Guido ;-)

...you need to force the cache to garbage collect before there are too 
many objects in memory. The catalog does this using subtransactions. 
there's also a cache minimize call somewhere, but you're probably better 
off asking on zodb-dev@zope.org about where that is...

Message-ID: <B04D245FBAA92241833B01C21BEC259E09E3136C@LMNFREX01>

Hi,

To clear some data caching I have made using _v_ attributes on one
particular object, I would need a way to programmatically clear its _v_
attributes.

As far as I understand, _v_ attributes are set per ZODB connection.
And they are cleared when the object is, for some reason, reloaded from the
ZODB to the connection cache.

As I use the current configuration :
+ ZEO
+ 1 Zope instance with RW connections to ZEO
+ several Zope instances with RO connections to ZEO

I was wondering if, setting self._p_changed=1 on the object from the Zope RW
would work.

Thanks for your help.

Pascal

Basically you can't. Although if a thread doesn't wake up for 10 mins (with
your object), then odds are it'll get thrown out and brought back in again
without the _v_ attributes set, so it's probably a moot point.

You would have to grab each ZODB connection present, grab your object and call
the method.. That's just getting in voodoo you probably don't actually need.

The best you could do would be to set a flag / timestamp. Any object that woke
up would have to check that timestamp and work out whether to flush at that point 
or not.

| Or do you mean that clearCaches() should do the self._p_changed=1 ?

_p_changed = 1 won't flush your _v_ attributes.

There is one very obvious way.... change a non-_v_ attribute of the object and 
commit it. Every other connection with an instance of that object in memory 
will lose the _v_ attribute at its next transaction boundary.

Subject: [Zope] metal Macros from PageTemplateFiles?
Message-ID: <cslncd$ibt$1@sea.gmane.org>

Is it possible (and how?) to use a procedure in a product to produce a 
PageTemplate that defines a macro, that can be used in another PageTemplate?

I tried:

   class SomeClass(Folder):

     content_template = PageTemplateFile("/some/file/template.zpt")

and the direct ssignment to a variable works, but it is not exactly what 
I need (I need to check with the actual instance).

But when I try to do:

     def content_template(self):
	pt = PageTemplateFile("/some/file/template.zpt")
	return pt

then the procedure is never called and I get an error in the ZPT that 
tries to use the macro:

   Error Type: AttributeError
   Error Value: content_templatemacros

Somewhere I read a vage reference to invoke "cook" but I don't know how.

Thanks

Subject: [Zope] recursion problem with newer security machinery
Message-ID: <41EE6595.8070900@ecn.purdue.edu>

Howdy,
We recently upgraded to 2.6.4, and are now having a problem with our 
custom UserFolder Product.  I've narrowed everything down to a few 
methods, but am at a loss on how to fix it.

In our UserFolder User class, we have overridden getRolesInContext to 
look for a Python Script (we call it an "authorize script"), in parent 
folders of the published object.  It then calls each script to 
programatically add roles at runtime.  This works great with Zope 2.6.2. 
  I have noticed that in Zope 2.6.4 the method Bindings._getContext in 
Shared/DC/Scripts/Bindings.py has new validate code in it.  I believe 
this is what is causing the problem for us.

What is strange is that this is only a problem when using 
ExternalEditor, and when the container of the object we are trying to 
edit contains an "authorize script".  From the ZMI there are no

Message-ID: <B04D245FBAA92241833B01C21BEC259E09E31381@LMNFREX01>

Pointers about what ?

If you mean about "And your ZODB grows everytime you want to flush the
cache..." :
Andrew is just saying that changing a persistent attribute of an object will
led to storing a new version of the object in the ZODB.

If you mean about "why I was asking how to clear _v_ attributes" :
I am using CMF 1.5.0 and SpeedPack 0.3, which monkey patches 2 CMF classes
to speed up skinned objects lookup by caching the result of previous lookups
in a new _v_ attribute on "CMF Site" objects. The performance increase is
huge (if you have lots of skins defined, and lots of folders for each skin
to be traversed). However, the situations that SpeePack "catches" to decide
to clear the _v_ attribute data are not enough for my needs. I need a way to
make sure that data is flushed in all connections.

Hope this answer your question.

Pascal

There is one very obvious way.... change a non-_v_ attribute of the object
and 
commit it. Every other connection with an instance of that object in memory will lose the _v_ attribute at its next transaction boundary.

The recursion problem stems from the fact that the new bindings 
machinery wants to ensure that the user has roles for the context before 
binding it, but you need the script to run to determine whether the user 
has roles.  The older code created a nasty security issue for sites 
which made it possible for untrusted users to write PythonScripts.

I don't know that this will work, but try giving the script
proxy role of 'Manager';  if that works, then you are set.

If it doesn't work, then I believe you need to look at converting your 
PythonScripts to instances of a "tool" class which can run the check as 
trusted code.

I already tried

   return pt.__of__(self)

but the error is the same. Also the function doesn't seem to get called 
at all when the page that should use the macro is requested.

(I use the __of__(self) of course for simple PageTemplates.)

Message-ID: <D6A86A535E1B81429619397E2B0D1BCA01460A7B@EXGCLUSTER.CORP.LOCAL>

My application streams pdf files from disk (not zodb) to the user, and
I've been writing the http header more or less manually.  I've had some
strange problems with downloading - one particular third-party pdf
plugin acts as if the file can not be found, and Internet Explorer
arbitrarily, yet consistently pops the Open/Save/Cancel dialog for 1% of
files, while launching a plugin for the other 99%.

 

My header looks like this:

 

HTTP/1.1 200 OK

Server: Zope/(Zope 2.7.3-0, python 2.3.4, linux2) ZServer/1.1

Date: Wed, 19 Jan 2005 17:08:30 GMT

Content-Length: 20004

Content-Type: application/pdf

Connection: close

Content-Disposition: filename="attachment.pdf"

 

Is there anything missing or malformed that could be causing trouble?

What about acutally changing some persistent attribute on the object ?
Would that work ?

Basically you can't. Although if a thread doesn't wake up for 10 mins (with
your object), then odds are it'll get thrown out and brought back in again
without the _v_ attributes set, so it's probably a moot point.

You would have to grab each ZODB connection present, grab your object and
call
the method.. That's just getting in voodoo you probably don't actually need.

The best you could do would be to set a flag / timestamp. Any object that
woke
up would have to check that timestamp and work out whether to flush at that
point 
or not.

| Or do you mean that clearCaches() should do the self._p_changed=1 ?

_p_changed = 1 won't flush your _v_ attributes.

What do you want it to do?

If you want the browser to display the file as PDF i.e. use a plugin if 
it has a plugin, then you should keep the Content-Type application/pdf 
and omit the Content-Disposition.

If you want the browser to treat the file as unknown i.e. display a 
download box, then you should change the Content-Type to 
application/octet-stream and the Content-Disposition to

Content-Disposition: attachment; filename="attachment.pdf"

At least that works for me.

Message-ID: <B04D245FBAA92241833B01C21BEC259E09E3138D@LMNFREX01>

Have you tried actually uploading a PDF File (as a ZODB File object) in
Zope, then setting the content-type to application/pdf, in order to compare
the headers you get when requesting that file ?

Pascal

P.S. : please use text format when posting to the Zope mailing-lists. :))

Objet : [Zope] http header question


My application streams pdf files from disk (not zodb) to the user, and I've
been writing the http header more or less manually.  I've had some strange
problems with downloading - one particular third-party pdf plugin acts as if
the file can not be found, and Internet Explorer arbitrarily, yet
consistently pops the Open/Save/Cancel dialog for 1% of files, while
launching a plugin for the other 99%.
 
My header looks like this:
 
HTTP/1.1 200 OK
Server: Zope/(Zope 2.7.3-0, python 2.3.4, linux2) ZServer/1.1
Date: Wed, 19 Jan 2005 17:08:30 GMT
Content-Length: 20004
Content-Type: application/pdf
Connection: close
Content-Disposition: filename="attachment.pdf"
 
Is there anything missing or malformed that could be causing trouble?
 
Nathaniel

It will but only in all other connections (i.e. not in the one
that executes the code above).

Also, it will cause writing of the object (and bloat your data file).

The "locale" module provides locale specific currency formatting.
You will need to declare it safe for use by untrusted code
before you can use it in Python Scripts, Page Templates or DTML methods.
Read the "README" of the "PythonScripts" product.

An alternative would be a Python Script that does the formatting you
like.

Two errors:

 1. as Tino already pointed out: you forgot the ".__of__(self)"

 2. you must call your "content_template" method (contrary to your
    "content_template" attribute).

    The easiest way would be a "ComputedAttribute", something like

        from ComputedAttribute import ComputedAttribute

	...
	def content_template(self):
	    ...

	content_template = ComputedAttribute(content_template, 1)

>Somewhere I read a vage reference to invoke "cook" but I don't know how.

PageTemplates get automatically "cook"ed, when necessary.

I had this problem with PHP powered site. IE would always ask to save
and never display with the plugin. Even when the headers were
identical it wouldn't work, but everything other than IE worked. I 
just ended up serving directly with Apache.

A quick thing first, the Content-Disposition header should look like this:

Content-Disposition: inline; filename="attachment.pdf" 

to make IE display in the PDF plugin.

That was not the main problem (as I had tried that before) but I tried 
to use the method in a traversal 
"metal:use-macro="here/content_template/macros/page" which didn't work. 
(Could that be made to work?)

Interesting, but I don't really understand the details.

Can I have an attribute and a method of the same name?

What does ComputedAttribute do? I found some documentation hints on the 
web but what's the second parameter? Can I pass parameters to the function?

OK, I found the solution and it's really wacky.  Apparently IE is
misreading the header, and if the word "attachment" shows up anywhere on
the Content-Disposition line, including in the file name itself, it will
spawn the dialog.

For example, the following will cause IE to launch the open/save/cancel
dialog every time:

  Content-Disposition: inline; filename="spb_bar_codes_attachment.pdf"

While the following will launch the plugin every time:

  Content-Disposition: inline; filename="spb_bar_codes_xyz.pdf"

Hey all,

  I just installed Zope Profiler to check out the performance of my pages and I noticed that I have a few bottlenecks on TALInterpreter calls that I'd like to clean up.  The issue is that the per call time seems a bit high on some of these.  Granted, I've got a lot more TAL statements in my page templates than I would like (eventually I will pull these out into scripts), but are these numbers unusually high?

ncalls  tottime  percall  cumtime  percall filename:lineno(function)
 11618/29    0.265    0.000   91.736    3.163 TALInterpreter.py:390(do_optTag)
 12242/29    0.282    0.000   91.736    3.163 TALInterpreter.py:382(no_tag)
       26    0.000    0.000   88.941    3.421 ZopePageTemplate.py:192(_exec)
    34/25    0.000    0.000   64.615    2.585 TALInterpreter.py:632(do_defineMacro)

Thanks for any advice.

What are you talking about? Zope X3 is out since November and
don't get Zope X3 confused with the "real" Zope 3.

<dtml-in expr="path.objectValues('CMF ZPhotoSlides')">

holden,

I don't know how to do this in dtml but in zpt I can create variables so
rather than doing path="wombat/&dtml-id;/" I would in zpt anyway do a
tal:define="mypath python:'wombat/'+getID()+'/'" and then have <folder
path="" tal:attribute="path mypath"

Can you do something similar in dtml??

<dtml-in "_[path].objectValues()">

You want to look up an object in the namespace, and to do so you must 
use dictionary lookup on the namespace (which is the variable "_".)

One could also use getattr or similar.

Think of it this way:

 >>> namespace = {"photos1":someobject, "photos2":someotherobject}
 >>> path = "photos1"
 >>> ph = namespace[path]
 >>> # being the same as...
 >>> ph = namespace["photos1"]
 >>> # which is like saying <dtml-var "photos1.objectValues()">

holden, take a look at the functions restrictedTraverse(path) and
perhaps unrestrictedTraverse(path).  These may not be the most
appropriate functions to use, but they will return an object reference
using a path (such as "folder/subfolder/page").  In your example it
could look something like the following:

<dtml-in expr="restrictedTraverse(path).objectValues('CMF ZPhotoSlides')">

This is, of course, relative to the folder/object you are currently "in".

If anyone has a more appropriate solution, I'd be interested in
hearing about it, too!

Hi again,

I reply just to put the answer here, in order to be useful someone else.

Following Chris instructions, I've looked at ZCatalogs code and found 
the way to free memory:

1) Use subtransactions when changing data, adding a 
get_transaction().commit(1) every X steps

2) Explicitly call the garbage collector of the connection every X 
steps, forcing the conection to release objects from cache and be 
adjusted to cache parameters defined in zope.conf.   This can be done 
with a self._p_jar.cacheGC()   (where self is a persistent object, 
obviously)

In my case, a readonly report, the second method is enought to keep 
memory in place.

Thanks very much to everybody

<dtml-call "RESPONSE.write(img.index_html(REQUEST, RESPONSE)"> will do the

Easy questions may have multiple answers. If someimage.jpg is a static 
image that really exists you could do it like this:

<dtml-var standard_html_header>
<dtml-var expr="restrictedTraverse(REQUEST.img)">
<dtml-var standard_html_footer>

This actually puts a standard image tag in the output (you probably have 
your own header and footer).

If the image is a dynamic entity or fetched from a database, then you 
need to use <dtml-call RESPONSE.setHeader('Content-Type','image/jpeg')>
rather than dtml-var, and then return the image content.

It all depends how complex you page templates are.

You need to find the slow/complicated bits and make them faster, if 
you're experiencing slow page load.

Message-ID: <038E38019B9E1541993E4E566C50C120389AC1@bbcxues02.national.core.bbc.co.uk>

Hi all,

I've setup a site search using ZCatalog and ZCTextIndexs that's happily
doing what I want, but I'd like to take a stage further. Is there a way
using the ZCatalog Brain objects returned by the ZCatalog search to get
the text that actually caused the match? I'm trying to end up with a
preview of the area of the content that caused the match, or is a
different approach needed? 

The only way I can think of doing this at the moment is to get the
actual content object via the ZCatalog brain object and then re-run a
regex search on the content, pulling out the text around any match. This
just seems the wrong way forward is there a better way?

Thanks for any pointers, I'm still very much in the newbie class at
present.

Brian

A Zcatalog search returns the objects (or better their proxies) that 
fullfill the query.
You have to grab the content from the object and perform post-query 
operations on your
own. There is no direct solution where Zope would help you out-of-the-box.

You can also have a look a SpeedPack to speed up TAL.
See : http://psyco.sourceforge.net/ to download and install psyco

And then see :
http://sourceforge.net/project/showfiles.php?group_id=55262&package_id=10732

To only use TAL optimization, you change :
PATCH_CMF = True
To :
PATCH_CMF = False
in config.py 

This works fine on Zope 2.7.3

It all depends how complex you page templates are.

You need to find the slow/complicated bits and make them faster, if 
you're experiencing slow page load.

Zcatalog searches<snip>
From: Brian Ling
Hi all,
I've setup a site search using ZCatalog and ZCTextIndexs that's happily
doing what I want, but I'd like to take a stage further. Is there a way
using the ZCatalog Brain objects returned by the ZCatalog search to get the
text that actually caused the match? I'm trying to end up with a preview of
the area of the content that caused the match, or is a different approach
needed?
The only way I can think of doing this at the moment is to get the actual
content object via the ZCatalog brain object and then re-run a regex search
on the content, pulling out the text around any match. This just seems the
wrong way forward is there a better way?
</snip>

You have to grab the text from the search result objects and do your own
matching (regex works).  Be careful to match for the same terms used in the
index (ie. if you have done any kind of stemming you need to take this into
consideration).  This is exactly what we have done for one of our sites
(shopwiser.com - you can see how it works by entering a search term and
seeing your search term highlighted in the results).

to get the same query terms the catalog matched you'd probably best to 
match the terms against the lexicon of the zctextindex (after all that's 
what the catalog query machinery does as well). The lexicon may be 
queried separately. The list of terms may also be useful for user feedback

Plone may release a new version for Zope 3 after it comes out, but not for
Zope X3.

I would suggest you use the latest Zope 2 (currently 2.7.4)

? I don't get what you mean. Of course its interesting to develop
Zope3 Apps, but currently you have to use ZopeX3 with its limitations,
so for production use I'd recommend Zope2. If you mean if its better
to start off with Zope3 instead of learning Zope2 that depends, if you
need to come up with an app soon, you might be better off with Zope2,
as there's no release plan yet for Zope3 (according to the website)
and ZopeX3 is not really meant for production usage AFAIK.

> And Products like Plone? Don?t work in zope 3??

First: Don't confuse Zope3 with ZopeX3, as I said already, Zope3 is
meant to be backwards compatible to Zope2, whereas ZopeX3 is a working
new release without any backwards compatibility (AFAIK).

So for Plone it's going to be a new release I think, as it's not a
small project and I would expect that Plone doesn't work out of the
box on Zope3. But simple Zope2 Apps should be ok.

Brian,

Some code you can use as a starting point to produce
KWIC (key word in context) can be found here:
http://zope.org/Members/Ioan/SiteSearch. It's old but
works for me under Zope 2.7.3.

This implementation requires the searchable text to be
in Catalog metadata, which seems to be a bad thing,
but I have never really understood just how bad.. 

The recent discussions about memory use have got me
thinking again about this; I would appreciate any
pointers to discussion/explanation of catalog metadata
and memory.

Best,

Ken

We have experimented with storing compressed and uncompressed metadata (up
to 20k bytes per zcatalog record).  This worked fine for us (in terms of
retrieval speed and zodb size) until we hit about 500k records (we used our
own KWIC scripts not SiteSearch).  At that time retrieval time started to
increase to unacceptable times (over 2 seconds per search) and the zodb
started to become unwieldly (5gb+).  At that time (slow retrieval speed) we
had about 5 million objects in the zodb (after packing).

I would suggest that storing lots of metadata is workable if:

1) you don't have a lot of records
2) you don't store too much metadata/record
3) you have lots (1gb+) of RAM
4) you have fast disks
5) you have a fast cpu

We currently have a zcatalog with a single ZCTextindex which holds about 1
million records (zodb size is under 3gb).  Our retrieval speed, include KWIC
processing, is under 1.5 seconds per search.  We have very little metadata
(less than 100 bytes per record), and access the final result set objects to
get the data we need for KWIC processing and result set display.

Not strictly true.  Several folks, including ZC, are deploying or have 
deplyed production applications atop X3.  YMMV, but the lack of backward 
compatibility is not a blocker for a new application.

Plone will have to be completely redone atop Zope3.  Some CMFish / 
Plonish technologies / techniques are already in Zope3;  others will 
need reimplementation.  Migrating existing Plone / CMF content is likely 
to be the hardest part of the conversion.

While setting the proxy role of 'Manager' does make things work for us, 
I'm confused as to why this is necessary.  (Also, setting proxy role of 
'Anonymous' works just fine too.)  Why is accessing an object different 
in the context of ExternalEditor compared to that of accessing it 
through the ZMI.

If I have a structure like:

/
/FOO
/FOO/authorize
/FOO/bar

I can edit bar just fine through the ZMI, but not through 
ExternalEditor.  I don't understand why there should be a difference 
here.  /FOO/authorize still has to be called by our UserFolder, whether 
it be from the ZMI or EE.

Thanks,
-Chris

I was "almost" tempted to move the project to PHP+Apache+PostGres. But
I am a ZopeHead ... always has been a big fan.

I have decided to use Zope274 for now. Hope fully I wont have major
problems when I upgrade to Zope3.

Now what I need is working a postgres DA for Zope274.....

Message-ID: <32A6682AE1A4C0479E50D9F1BCFBC2811409B3@s-lyo-exc1>

Hi,
I want to upgrade my Zope-2.7.1 to the lastest version Zope-2.7.4 in
Windows. As far as I know it might be done by simply installing Zope-2.7.4
(using the executale binary Zope-2.7.4-0-win32.exe) over the existing
Zope-2.7.1 (meaning the destination directory will be the existing Zope
home). 
I have created many Zope instances (using Zope-2.7.1) running as Windows
services. So if I upgrade the existing Zope-2.7.1 (rather than install
Zope-2.7.4 in a new directory)  then I don't have to make any change into my
existing Zope instances.
Could anyone tell that this is the right thing to do it or I would miss
anything?

Thanks,

Trung Tran

What I would like is something more like the newsreader I use now 
(Thunderbird).  Users create items in a nested hierarchy without having 
to create folders to store subitems.  I can view the hierarchy and 
decide where I want to jump in and open up the detail or easily add 
detail at the appropriate nesting level (through a reply).

Message-ID: <20050120231425.GF6843@asu.edu>

I'm looking for ways to secure webdav. I am using apache to front end
zope, using fastcgi like this:

     FastCgiExternalServer /home/www/cmf  \
          -host localhost:8089 -pass-header Authorization

This works great. I looked and using rewrites and proxypass by wanted
to keep the source ip passed along in the request to zope.

Anyway, is there a way to have apache pass webdav requests as well
through https ?

I am currently using stunnel to secure webdav traffic, but I thought
there might be an easier way.

Message-ID: <B1F6EDA0-6B39-11D9-B8B7-000393D58818@zope.com>

Zope Corporation is delighted to announce a new
training course on Zope 3.

Zope 3 for Developers
---------------------

This three day course will familiarize developers with
Zope 3 software from introductory through advanced
concepts. The take-away materials provide tools for
further learning, since it will not be possible to
cover every topic in the sessions. We will demonstrate
the flexibility and effectiveness of Zope as an Open
Source web development Platform.

Course Objectives:

After completing this course students will understand:

     * Zope's component architecture,

     * Creating Zope components and applications

     * Building web interfaces,

     * Controlling security,

     * Using powerful Zope framework features e.g.,
       events, metadata, schemas, testing,

     * Configuring and installing Zope

The course is intended for developers who want to build
web applications using the Zope 3 web-application
server.

Students should be familiar with the Python programming
language and the concepts associated with web
application development.  While not required, students
will benefit from having some familiarity with Zope
2-based application development.

We offer several opportunities to meet with Zope's
engineering teams, including with Jim Fulton, our CTO.

The sessions for 2005 are:

   o April 18-20
   o June 27-29
   o Sept 19-21
   o Dec 5-7

For more detailed information about the course,
including pre-work, pricing, travel and accommodations,
please go to our website www.zope.com.

Regards,
Rob

WebDAV looks like any other HTTP request to Apache, so you can handle 
it with things like RewriteRules etc. No special magic involved.

Create a folder-like type that implements your task item, and can 
contain other task items. The users will never know that the task item 
is really a folder: why should they care?

Create a view that displays a tree of your items.

You have exactly what you want.

Trung,

I did this recenly, rather than using the windows install I downloaded
just the source code files and copied over the old files.  It worked
perfectly well.  Without a hitch actually.

Message-ID: <BAY102-DAV10B045DBDC5112B28D8F0CFF820@phx.gbl>

Apparently the distribution creation machinery is not respecting the
"Disallow redistribution and allow user ..." option.
This are the steps I followed to reproduce the problem using two new Zope
instances.

a) Created two Zope instances, A and B. Created a foobar product in
Control_panel/Products, in instance A
b) Created a simple ZClass, using ObjectManager and OFS Folder as Base
Classes, checking "Include standard Zope persistent ..."
d) Went to Control_Panel/Products/foobar and the Distribution tab, checked
"Disallow redistribution...", without checking any product's object, and
then I created  the distribution tar.
e) Installed the "foobar" product in instance B. After starting instance B,
the foobar product is not redistributable but fully editable, even though I
didn't allow any object to be configurable..

As I recall, this is wrong, and all of the objects ought to be protected, in
this case. Could anyone point me in the right direction?  I'd like some
hints on this subject.

Thanks in advance,


Ausum

I don't see anything in what you've said that makes using Zope Folder 
objects as you items, storing info using Properties.

It seems you're arguing about UI, so build the UI you want :-)
Or, if you've got budget, pay someone else t obuild it for you!

That should work, but means you're stuffed if you want ot go back to 
2.7.1 for any reason...

Well, what I've done, and has worked for years on both Linux and 
Windows, is to install the Zope software in folders related to their 
version, eg:

E:\Zope\2.7.1
E:\Zope\2.7.4

I think create projects as instance homes:

E:\Zope\myproject1
E:\Zope\myproject2

Then, all I need to do to upgrade is install the new zope software 
(putting 2.7.whatever in the location box for the binary installer) and 
then tweak the start scripts (you'll have to fiddle with the service 
start scripts) and zope.conf's of the instances I want to upgrade, 
restart them, and you're done :-)

cheers,

Chris

I dont discover any python simple way how to recode these characters into wml,

Hi, after wanted to index PDFs and MS Office files, I found various items on
the internet which point to the use of ZAAPlugins and PloneExFile. This
seems to work well.

However, openoffice files (.sxw, .sxi for example) aren't handled or
recognised. Is there a solution or plugin for this?

Even if there is none, can i override the defualt icon that is displayed for
these images? The question mark icon is a little confidence-uninspiring! I
did try to use the "find" tool on zope to find a mapping from extension/type
to icon but couldn't find one.

There is no python 1.5 anymore too ;)
See python.org, windows download. There is a link
for up to date (and your zopes python version matching)
win32 extension.

Maybe the author can answer this.

It isnt there anymore. Zope2.7 has
a different startup. You can change
the python interpreter zope uses if 
you look into the start files in your
instances bin directory.
At least there should be something like
runzope.bat (for windows) I dont know
if there is a zopectl.bat too. Change
every occurence of the python interpreter
here. Make sure you use the same python
version (2.3.4 or so)

Hi,

I would like how to activate the History tab an a simple conent object that

Do I only need to make it inherit from Historical ?

Yes, Zope X3 is production quality.

I agree. I think there will never be a Zope 3 that is backward-compatible. It 
would take a huge amount of work to provide such a layer. Compatibility will 
come through a layer that interfaces Zope 2 and Zope 3, such as Five. In fact 
I think Five will become *the* one.

Note: Not all Zope 3 developers share this view with me and I am not 
expressing the opinion of the Zope 3 community here, but only my own.

To answer the original question, if you do not want to build a plain Web site 
or CMS, then you should definitely have a look at Zope X3, since it is a very 
nice framework to develop Web applications with.

Stephan

Subject: [Zope] Making a self written module available to Zope
Message-ID: <41F12B7F.5060109@homemaster.cn>

If I have a self-written module/package which contains some module level 
methods, how can I make it available for use in the rest of Zope (e.g. 
in page templates, python script objects etc.)?

Because it is just some utility functions, like the zope built-in 
sequence module, I don't want to register them as a zope class with all 
the manage* methods and create zope object from that. And I want the 
module to be initialized once, upon the start of zope or refresh of 
product maybe, to read some configuration file on the file system. 
What's the simplest way to achieve this?

Greetings,
Hong Yuan

a trivial example:

# this is Products/MyFunctions/__init__.py

from AccessControl import ModuleSecurityInfo

def trivialFunc():
   return True 

def anotherFunc():
   return False

ModuleSecurityInfo('Products.MyFunctions').declarePublic(
    'trivialFunc', 'anotherFunc'
    ) 

# EOF

Note that you cannot declare module-level functions
protected by a particular permission; you can only declare 
them public.
See lib/python/AccessControl/SecurityInfo.py.

You may also find AccessControl.allow_module() useful.
It's defined in that same file.

At least, you also need to extend your "manage_options"
and probably, you also can provide an adapted comparison.

You should *NOT* put fields into the metadata table
if they could be larger.

We had put the "description" into it and observed
huge transactions (a few byte change to a news
resulted in a 500 kB transaction) with correspondingly
large modification times. Searches, too, were very slow because
such huge blocks had to be loaded from the ZEO server.

Read large volume data from the object directly.
This is efficient, when you need it only for individual
objects or the objects in a moderately sized batch.

Thank you Andreas!

But neither of these products can help with KWIC or

In language Zope newbies can understand, how is that different from what 
Zope 2 promises or is recommended for? If I am starting a new project, 
what criteria should I use to decide if I should start with Zope 2 or just 
jump right to X3 to begin with?

Okay, so the first thing here is that Zope 2 has a much wider target audience 
than Zope 3. Zope X3 (as of now) is aimed at the Python developer, who uses 
Python code and Page Templates to develop applications. As you know, Zope 2 
is also useful for scripters and almost the average Joe, since it provides 
scripting and Point&Click interfaces.

I think the solection criteria is: If your application will provide common Web 
features, Zope 2 is the recommended way, because it is almost guaranteed that 
this feature has been already implemented. If, on the other hand, you write a 
very specific and unique application, Zope 3 is better, since it provides a 
much cleaner and simpler API to develop on and with.

Stephan

I was hoping to use Zope3X, however, infrastructures like "native"
postgres DA and LocalFS are not "available" for it (I am required to
use the WinXP).  I wanted to learn about Zope3 doing this project.
Right now the project is the priority and not learning/hacking Zope3X.

Yes, there is a native postgres DA. It even has been released for Zope X3.0. 

See http://zope.org/Products/Zope3-Packages

LocalFS does not exist for Zope X3 yet, but for what do you need it? BTW, it 
would be fairly straight-forward to implement LocalFS for Zope 3.

Subject: [Zope] Plagued by UnicodeEncodeError and UnicodeDecodeError 
Message-ID: <20050122005805.GB20812@mail.imagesmiths.com>

Hi,

We have a ton of AT objects that we've imported from our databases, 
some of which are Japanese characters imported as unicode.  In some
cases, those could not be imported because of UnicodeEncodeErrors
or UnicodeDecodeErrors loading the object from our DB or loading
them into the ZODB.  It would have been really nice to keep these
entries, but we just put them in a try:except: block to get past
them.

Our current problem is that now we have the data in our DB, and they
all display fine.  But when we go to edit them through a base_edit
and click Save, we're back to this:

The current Archetypes has a strange handling of text data:

    Internally, it stores it as unicode (good!)
    but it tries hard to deliver the content encoded.
    I am not even sure, there is a way to tell it to deliver
    unicode; but at least you can pass in the encoding your
    want ("encoding" keyword argument).

AT 1.3.1 uses "instance.getCharset()" as "encoding", if not
specified explicitely. This is better than previous versions
that used the "original encoding" (which could mix different
encodings in a single page).


By the way: the Archetypes mailing lists are probably better
suited to discuss Archetype related questions.

Thanks for the sample and now I can access trivialFunc() from within a 
template file using:

<p tal:content="python:modules['Products.MyFunctions'].trivialFunc()"></p>

It works fine, just somewhat cumbersome. One way to simplify its usage 
is to use tal:define, like:

<p tal:define="func python:modules['Products.MyFunctions'].trivialFunc"
     tal:content="func()"></p>

But this would require using tal:define in every template file that 
could access the function.

Is there any other way to simplify the access to the function?

Yes, simply dont write application code in pagetemplates :-)
You can either stuff your complete API in context by defining
useful classes and methods or do the support scripting
in one or some python scripts.

First of all, thanks Dieter, that answered my question 1.

Now I've got a more serious problem.
I have a CMF Document that wraps a PageTemplate object (it does not extend
PageTemplate, but internally stores a PageTemplate instance).

It looks like when some revision of my object is retreived from ZODB, this
does not include the wraped persistent objects that my object may contain.

For example, rev1._get_pt.read() and rev2._get_pt.read() always return the
HTML of the current revision's wraped PageTemplate.
(_get_pt() returns the wraped PageTemplate object)

Is there a workaround for this ?
The only thing I can think of is storing the PageTemplate HTML at my object
level each time it is changed, but that means storing the HTML twice in
ZODB...
I tried it, and of course it works.

Pascal

The only workaround I see right now is to get the list of historic
versions for the subobject too, then select the version
which timestamp is just below or equal to the timestamp of the
container objects historical version.

Maybe I add something like that to the historical patch for folders.

Indeed: each persistent object has its own independent history.

>Is there a workaround for this ?

When you have complex objects (consisting of several persistent objects),
you must merge the histories of the components or select
one (major) component to define the history of the compound.

I have something like a historical connection.

It does not help with the history merging but it helps
to present a consistent view once you have chosen
a time you are interested in.

Subject: [Zope] MySQL Windows Driver Updates
Message-ID: <41F4F17B.10387.18415633@localhost>

Have Zope MySQL database drivers (ZMySQLDA and DB) and ODBC (ZODBCDA) 
development been abandoned for the Windows platform?

Most of what I can find is very out of date (no longer works with the 
current release), experimental (with major problems), or commercial.

My need is to hook Zope 2.7.4 up to MySQL 4.0.16. on a W2K server. My 
preference would be the native driver. At this point, it looks like 
the eGenix commercial solution may be ony viable option, and I really 
have no idea how good it is.

If anyone has gotten this MySQLDA mess working in such an 
environment, I would be grateful to know how you did it.

I managed to retrieve revision 1 and 2 of the subobject in the comparison
method of the main object by using the methods defined in OFS.History
and comparing _p_mtime. It works fine.

Hi,

I would like to know if anyone has some advice to give me on this.

Inside one Zope instance, I have 2 folders, representing a live site and a
development site.

People copy objects from dev to live when they are ready.

I would like to know if there are things to avoid (in order to speed up
overall comparison time).

I was thinking about a recursive function that would follow the development
site folders structure, and on each folder, compare contents with live
content, using comparison methods by meta type.

Thanks a lot.

Pascal

Subject: [Zope] Problem with external method locking threads
Message-ID: <41F56277.9090302@apmindsf.com>

I am running an External method, to fix some hard links in our ZWiki 
back to relative links.  On two of our three ZWikis, this script
runs well.

 On the third ZWiki, which has about 530 pages, this script causes the 
Zope instance to stop responding to any requests, after it
processes about 140 pages.  I have tried deleting the pages it freezes 
on, but it still freezes at about the same place each time.

After examing the lists, and running strace, I am certain that one of 
the Python/Zope threads refuses to respond to SIGRTMIN, and then
somehow locks up all threads - however, this is deeper than my knowledge 
goes, and I am hoping someone on this list can point me towards
solutions I have not yet tried.

Software RAID 1, using a 36GB partition for Data.fs.  Directory 
instance/var is a symlink to this partition.
Python 2.3.3 and Python 2.4
Zope 2.7.3
ZWiki ZWiki-0-37-0
glibc-2.3.4-3

Below, I have copied:
The External Method script I am using
A brief description of the various things I have tried
A sample of the environment, from within zopectl
A copy of the strace run I am getting during script execution

I use the command 'setuidgid zope bin/zopectl' to run the Zope instance.

Any help is greatly appreciated!
David

-------------------- The script looks like this:
from StringIO import StringIO
import zLOG
import re

def addpage(self,o):
    """ Given a file or image, convert links to LocalFS """
    nid = o.getId()
    fileOnlyLink = re.compile(r'href=\"([- .\w]+\.\w+)\"')
    fileLink = re.compile(r'https://zwiki(?:.*?/)+?([- .%\w]+.\w+)"')
    otherLink = re.compile(r'https://zwiki(?:.*?/)+([- %\w]+)"')

    pageText = o.read()

    pageText = fileOnlyLink.sub(r'href="uploads/\1"', pageText)
    pageText = fileLink.sub(r'uploads/\1"', pageText)
    pageText = otherLink.sub(r'\1"', pageText)
    o.setText(pageText)
    zLOG.LOG('addpage', zLOG.WARNING, 'working on %s' % nid)
    o.reindex_object()

Google for "debug spinning zope", that may give you more
clues.

Speaking for ZMySQLDA, there have been no new releases for more than
two years because there's been no need to release anything: It works.
There's never been any development for the WIndows platform because
it's cross-platform, and there's nothing platform-specific in
ZMySQLDA.

There is one prerequisite for installing ZMySQLDA, and that is
installing MySQLdb.

http://sourceforge.net/projects/mysql-python

Availability of pre-compiled Windows packages depends entirely upon
end-users who have the tool chain to build them. So far there is not
an installer for 1.0.1. However, 1.0 or even 0.9.2 should be fine for
Zope; most of the changes are in the Python layer which is not used by
Zope.

Subject: [Zope] sql_delimiter broken?
Message-ID: <41F50E8F.11341.18B2EDCA@localhost>

The ability to pass multiple sql calls in one ZSQL method using 
sql_delimiter seems to be broken in 2.7.4.

This no longer works in a single ZSQL method:

INSERT INTO ...;
<dtml-var sql_delimiter>

INSERT INTO ...;
<dtml-var sql_delimiter>

Crashes the sql on encountering the sql_delimiter.

Does anyone know of any workaround outside of using separate ZSQL 
methods for each statement? I know... convert it to Python.

Subject: [Zope] ZODB storage errors ...during object abort
Message-ID: <200501250306.WAA24475@courageux.cnchost.com>

Hi,
I'm investigating some nasty hangs/freezes that seem to occur every 2-3 days. Usually, i just "service zope restart" and I'm back in business.

So I turned on event logging on the last restart to help figure this out and Zope hasn't hung yet, but I've been seeing these nasty looking errors (esp. "This shouldn't happen")

any ideas, hints, debugging paths that might shed some light on this error would be greatly appreciated!!!

thanks,
io

Please belay this problem - it actually appears to be a problem with my 
choice of regular expression.

the 'fileLink' regexp in the script goes into never-neverland for some 
links that have query strings containing links.  Once in this state, 
Python has to be killed to stop it.  Who'da thought infinite recursion 
could take so long...

I've cleaned up some of the worst in the appendices, but there's a lot
more to go through.  I think I caught all the wiki spam in the
appendices, and I integrated a few comments into the text (mostly typo
corrections and the like).

There's still a lot of cleaning up that's needed, but I don't have the
time to do a lot of this myself.

No, just dont use 2 delimiter. 
You have used ; _and_ sql_delimiter which would render to ; 
too. I'm also not certain if the syntax was correct.
It should be something like sql-delimiter
Which renders ; too :-)

Great!
... only, I worry this will not make it into the 2.7
version of the book unless somebody takes care to
merge your work?
http://plope.com/Books/zb_signup
The people working on appendices are listed there:

 25  Appendix A: DTML Reference          (David Siedband - in progress)

 26  Appendix B: API Reference           (Paul Winkler - in progress)

 27  Appendix C: Zope Page Templates Reference  (Thomas Reulbach - in progress)

 28  Appendix D: Zope Resources          (Jens Vagelpohl - finished)

Hmm.  If the version on zope.org is not canonical, it shouldn't be
editable (annotatable, yes, but not editable).

I'd really like to see documentation maintained like other sources,
using a revision control system (Subversion would be ideal, but CVS
would be a step forward, IMO).  Having yet another place to go doesn't
help.

Hopefully someone with the right access, Zen, and time will take a
look at the changes and merge them into the source documents.

The eGenix driver is very good. The support for it is even better.

That said, what Andy says about the MySQL native drivers is true...

This could be a problem.

The reason I've shyed away from doing anything is 'cos there seems to be 
confusion as to whether book development happens on Plope.com or Zope.org.

Chris, can you comment?

Indeed. I don't think the BackTalk feature has really helped all that 
much, people just abuse it :-(

There is a sourceforge project for this, how do we go about using it?

Looks like the MySQL connection is your problem. Is there a chance your 
Zope server is loosign communication with your MySQL server?

Hi,

Something went wrong with my Zope overnight.

I attempted to restart this morning, but Zope dies
after serving a single page. Strangely, although I can
retrieve one page, there is no entry for it in Z2.log.


How shall I interpret this message from my Error.log:

Did you tried to move away the old Data.fs* (backup first!) so that you 
can check if it is a sysadmin problem or a Zope problem?

Also, I see a strange message stating 'no address associated with 
hostname'... not sure if it can cause problems.

Marco

Yes, thanks, I have backups. And I forgot to mention,
I am running Zope 2.7.3/FreeBSD 4.9.

Actually, I suspect it is not strictly a Zope problem.
Squid (which I stopped) was running fine, and I was
able to reboot the machine (remotely) with no effect.
My ISP-friend, who gets to work in about 6 hours, may
(or may not) be able to help with any admin-type
issues, so any help from the list will be much
appreciated.

Subject: [Zope] epoz and zpt
Message-ID: <41F6368C.2030809@bvx.cz>

Could someone please post the simplest working example of Epoz 
in ZPT? An example that would edit a file called 'text'.

The following code I figured out works but it does not save to 
a file:

ZPT method /epoz/a:

<form action="/epoz/a" method="post">
<span tal:define="text here/text|string:"
   tal:replace="structure python: here.Epoz('text', data=text,
                                            toolbox='/',
                                            lang='en',
                                            style='width: 
620px; height: 250px; border: 1px solid #000000;')" />

<input type="submit" name="submit" value=" Save Changes " >
</form>

What's wrong with my example?

I'm back in business. A list post from 1999 (by Amos)
tipped me to the likely cause: something must have
changed with the dns server specified in my zope.conf
(start.py at the time).

I reverted to the default (unset).

Please remember: Epoz is a replacement for a HTML-textarea... your 
example wouldn't work for a textarea, because your form-action redirects 
to the template itself... you need an action (PythonScript) which does 
the process of storing the request-data into an object.

So my advise: Develop your application with a normal textarea first, 
when it works, replace the textarea with Epoz.

Cheers, Maik

This is almost certainly due to trying to use non-transactional
tables. Are you using MySQL with transactions enabled, and are your
table types MyISAM or BDB or InnoDB? The latter two support
transactions, and as a practical matter, you need transactions to work
properly with Zope.

We moved the development to plope.com because zope.org is slower than
molasses in winter (totally unacceptable response time for editing). 
I'm not sure what it will take to fix that or even if it can be fixed. 
I'd be happy to move development back to zope.org, but I admit if it's
as slow as it has always been when we do, I won't have the patience to
contribute very much.

Your diagnosis is correct (I missed the semicolons first time around).
However, <dtml-var sql_delimiter> does NOT render as a semicolon. It
is, in fact a zero byte (\0). The ZSQL Method machinery uses that as a
split character since it is (AFAIK) impossible to put in the query as
a literal value ('\0' for example would be interpreted as backslash
zero). Since it is a split character, you don't want one at the end,
either. Also, while it's not an issue here, it's worth pointing out
that you can only have one SELECT statement in a ZSQL Method.

So to sum up, what he needs is:

INSERT INTO ...
<dtml-var sql_delimiter>
INSERT INTO ...

with no semicolons in sight.

Well, the other option is to just continue using plope.com I suppose and
only move them to zope.org when they are "done".  Serving up the docs
for reading and commenting from zope.org is fine performance-wise, but
serving them up for editing them really isn't.  

Of course, getting "done" is a whole other story.  ;-)  I've been remiss
in my duties here.

Ah yes, while 2 selects indeed are possible (just checked)
I guess it depends a bit on the database. But you only
get the result of the last SELECT of course.

You can look at "bobobase_modification_time()" (time of the

Agreed. But I don't have access on zope.org to change the
permissions on the book.  I have no idea if the workflow even
supports such a state.

I disagree, having edited a chapter for the 2.6 edition
and working on one for the 2.7 edition, many of the comments 
are invaluable.

+1, a couple people volunteered to help me with appendix B
and it's been a pain coordinating that "by hand".

As always, lack of time is the big problem.

Or use the sourceforge book project CVS.
I tend to agree w/ Fred and Chris W that this would be
better and, in the long run, easier.

That'd be fine as well.  The only real reason the dev versions are
Backtalk now is in order to have them available for display to docs
seekers.  We could maybe just ditch Backtalk/STX altogether, but I'm not
sure what the alternative is.  I do think the commenting features are
valuable, as much as they may be abused.  I'll also note that the last
change made to the development docs was many months ago, and I'm not
sure that moving them into another system will improve that in any way.

There's no need to move away from STX, and doing so at this point
would be a nuissance.

I've no objection what-so-ever to making the documents annotatable,
though it's not clear to me that BackTalk is the right way to do it. 
The problems I see are:

1. General editing in the non-canonical location is bad, and
misleading for potential contributors.  This is especially true for
occaisional contributors like me.

2. Being able to incrementally update from the maintained version
without losing annotations seems necessary, unless we require that all
annotations be handled or integrated by the time the update is
performed.  Such a requirement is not acceptable.

I don't know if BackTalk can be used that way, or can be easily
modified to do so.

Given the synchonization issue, I'd gladly give up the annotations if
the documents became easier to update, and have the updates actually
make it to the published version (regardless of where that is).

My thought was that the cvs project would just contain
stx files that we can upload as Backtalk chapters.

This would mean we should figure out a workflow for
the ZODB data and a release process for the CVS data
that allows us to merge in both directions (i.e.
merge zope.org comments to CVS in preparation for
editing a chapter, and lock the zope.org version
for a short period of time to allow getting the
cvs stuff ready to deploy; then upload to
zope.org and unlock it.) 

This is basically what we're already doing on an informal
basis.  I've had to search through the zope.org version of 
Appendix B a couple times, looking for comments added
since I started work.  And I have to manually keep track
of when I last did this.

You mean the dev guide?  Yeah AFAIK nobody does much with it.

Not being able to work in the "canonical" location at all kills the 
"ongoing contributor" pool, which is worse.

The BackTalk version *is* the canonical version for Zope 2.7, so the 
synchronization issue doesn't exist.

-1 to moving the project *anywhere* except to zope.org.

-1 to moving it to zope.org until after its "author-hostile" problems
    get fixed.

+1 to turning of annotations for the 2.6 version of the book on zope.org
    (any value there is long lost).

The canonical location is pretty broken ATM, however.  At times, it can
take several minutes to save a document.  At least that was the case
when we decided to move the development docs to plope.com.

AFAIK, there is no incremental update to be done from the maintained
version.  There is only one maintained version of the 2.7 book at the
moment, and that's on plope.com.  The 2.6 version is no longer
maintained.

I'm not sure there is a synchronization issue.  There's definitely a
locking issue... not allowing people to step on each others' changes. 
But this is currently handled manually (via the maintenance signup
process) as well as via DAV locking.

The 2.6 book commenting feature should be turned off now that the 2.7
book is in development.  That it hasn't been is an oversight.  When the
2.7 version is finished, it should accept comments (it currently
doesnt).

All that said, I'm happy to do whatever everybody else wants to do.  I
understand that not everyone is a fan of the commenting feature,
although I do think it contributes immensely to the docs, especially
during new version development.  There is also a feature to turn *off*
the comments on the viewed output but it appears that it's not "sticky"
at the moment... it needs to be clicked for every page.  Not sure why
that is.  That can be fixed, if it made any difference.

Please god not another intermittently-available sourceforge CVS 
project.. we have a zope.org SVN repo, no ?

I don't have a real answer to this problem, but I can tell you what the 
energetic ubuntu folks are doing just now.

They started with a wiki (moin, then zwiki; imagine 
your-rapid-web-based-tool-of-choice here).  The wiki was and is the 
primary place for making quick notes, gathering and organizing input 
from the wide user community with minimal hassle (after irc and the mail 
lists).

Now they are working on some more formal docs in SVN using docbook, xml 
include features etc, which can generate multiple output formats. For 
these they harvest the wiki content (and eg 3rd party docs like 
ubuntuguide.org).

PS so, for anyone thinking about whether SVN/docbook might be the way to 
go, the ubuntu-doc archives are worth reading.

Subject: [Zope] Using pychart from a Zope product
Message-ID: <41F6F57D.1030202@lerner.co.il>

Hi, everyone.  I'm developing a Zope application that needs to do simple 
line-charts, and PyChart looks like a good solution to my problems.

I was able to install PyChart without any trouble, and I also ran the 
command-line tests without any problems.  But when I stick an example 
into a Zope product and invoke it, I get nothing -- not an error 
message, not an output chart, not a security violation of some sort... 
nothing at all.  I know that PyChart is being invoked, because I can 
force an error by invoking theme.get_options(), which throws an error 
due to the lack of command-line options.

I see from the various Zope mailing lists that people are using PyChart, 
and I have a feeling that I'm missing something obvious.  But if someone 
has an idea regarding what I should be doing in order to get PyChart to 
work, I would greatly appreciate it.

Thanks!

Is this really the *full* traceback? Any headers missing?

I agree, STX is fine, and comments are worthwhile provided there's a 
canonical place to update things crap comments can be weeded safely and 
good comments can be integrated back ASAP.

The problem I see is that with a source repository, you'll forever be 
synching with the ZODB copy and worrying about comments. Years ago, I 
dreamed of something ViewCVS-ish that could render stuff instead of just 
checking it out, that way anyone could instantly view and comment on any 
branch and usual version control practices could be used to control what 
changes happen and where.

Sadly, I don't think anyone has the time to develop such a beast ;-)

So, I reckon we should stick with the current software, and do work in 
one canonical place. Although I do have some feature requests:

- make that f'ing comments button stick, and be off by default ;-)

- add a check box per chapter that lets an Editor lock a chapter for 
editing. This is a shroter term thn the chapter signup on Plope.org and 
just lets you lock the chapter so only you can edit, while you're 
editing. Anyone leaving a chapter in a locked state at any other time 
should be neutered...

Which development docs are you referring to?

Which backtalk version though? The one on Plone.com or the one on Zope.org?

Agreed, after reading this thread. Sourceforge won't help here without 
more development work than is likely to happen.

Does this mean "officially" making Plope.com canonical until zope.org is 
ready?

If someone tells me how, I'll get on and do it...

Yes,

1) you can use a python expression when calling, like:
calling DTML method (test1):
   <dtml-var expr="test2(param='a dtml method')">
called DTML method (test2):
    this is a <dtml-var param>

2)you can set a parameter in the REQUEST, which is global, but i 
wouldn't do it

Subject: [Zope] Generating editable grid with Zope2.6/ZopeX3?
Message-ID: <16054.1106741909@www57.gmx.net>

Hello,

I want to generate an editable grid with Zope (2.6 or X3).
E.g.

Field 1 | Field 2| Field 3
--------------------------
Id 1    | Edit 2 | Edit 3
Id 2    | Edit 2 | Edit 3
Id 3    | Edit 2 | Edit 3
.
.
.

I've already looked into Formulator for Zope 2.6, but this product doesn't
seem to be able to render :records objects.

Is it possible to render such a form with zope?

Manual alignment is ok, but I would like to use the input validation
mechanisms that are provided by Formulator or ZopeX3.

Regards
Florian

In pure-zope (non-cmf-ish) you could very well use Formulator
but you would need to provide a custom layout template (or at
least you needed that when I last used formulator).

If you find a better solution, let me know ;-)

Message-ID: <Pine.SOL.4.20.0501261104070.15489-100000@santiam.dfci.harvard.edu>

Hello ...

I've been following the Product creation example in the 2.7 Zope manual
(at http://www.plope.com/Books/2_7Edition/CustomZopeObjects.stx).  The
very first portion has one create a trivial product which can be selected
to add via 'Hello' and thus call the 'hello' method from earlier in the
example.  However, when I go to add this product, I get the login dialog
constantly (yet I am already logged in) and if I hit 'cancel' to avoid it
get the error:

Error Type: Unauthorized
Error Value: You are not allowed to access 'title_or_id' in this context

Note that I have a stock/brand new zope instance that I'm working on and
have not edited the permissions from the defaults in any way.  Is there
some permission change that I need to make for this to work?

Thanks
-J

As if any more evidence were needed that the current situation
is untenable, I just attempted to figure out what Fred changed.
The diff between the zope.org version and the plope.com version,
according to diff -b -B, is now over 6203 lines long.
There is no way in hell I'm going to sort that out.

It feels too much like Fred and I are being punished for trying to help out.

I'm fine with any other solution.  I don't really have a problem with
the current one, but if it makes things easier for all involved, I'll
get behind whatever folks come up with.

I can't really point to specific messages, there's too much going on - 
but a good way to find things of interest might be to point thunderbird 
at nntp://news.gmane.org/gmane.linux.ubuntu.doc and filter on 
"ubuntu-doc report".

Be warned. You will loose the DTML namespace with this.

For details, please read "Calling DTML Objects" in

  <http://www.dieter.handshake.de/pyprojects/zope/book/chap3.html>

3)
   Usually (when you call DTML objects correctly), the
   DTML namespace is global. I.e. any variable in the DTML
   namespace visible at the calling point is visible inside
   the called DTML object.

You are missing that we need your piece of code that interfaces
"PyChart" with Zope. How do you pass the result of "PyChart"
back to Zope/ZPublisher?

Without this information, we (at least I) cannot help you.

For now, I just wanted to save the resulting chart to disk, just to see 
if the darned thing would produce any output.  My next question was 
going to be if there's a more intelligent way to integrate PyChart with 
Zope than saving charts to a directory that's exposed to the outside 
world via the Web.

The following is the method that I wrote in my Zope product, taken 
almost 100 percent from one of the demos that came with PyChart:

        def return_basic_chart(self, REQUEST):
            "Return a basic chart"

            can = canvas.init("/tmp/chart.pdf")

            # We have 10 sample points total.  The first value in each
    tuple is
            # the X value, and subsequent values are Y values for
    different lines.
            data = [(10, 20, 30), (20, 65, 33),
                    (30, 55, 30), (40, 45, 51),
                    (50, 25, 27), (60, 75, 30),
                    (70, 80, 42), (80, 62, 32),
                    (90, 42, 39), (100, 32, 39)]

            # The format attribute specifies the text to be drawn at
    each tick mark.
            # Here, texts are rotated -60 degrees ("/a-60"),
    left-aligned ("/hL"),
            # and numbers are printed as integers ("%d").
            xaxis = axis.X(format="/a-60/hL%d", tic_interval = 20,
    label="Stuff")
            yaxis = axis.Y(tic_interval = 20, label="Value")

            # Define the drawing area. "y_range=(0,None)" tells that the
    Y minimum
            # is 0, but the Y maximum is to be computed automatically.
    Without
            # y_ranges, Pychart will pick the minimum Y value among the
    samples,
            # i.e., 20, as the base value of Y axis.
            ar = area.T(x_axis=xaxis, y_axis=yaxis, y_range=(0,None))

            # The first plot extracts Y values from the 2nd column
            # ("ycol=1") of DATA ("data=data"). X values are takes from
    the first
            # column, which is the default.
            plot = line_plot.T(label="foo", data=data, ycol=1,
    tick_mark=tick_mark.star)
            plot2 = line_plot.T(label="bar", data=data, ycol=2,
    tick_mark=tick_mark.square)
           
            ar.add_plot(plot, plot2)

            # The call to ar.draw() usually comes at the end of a
    program.  It
            # draws the axes, the plots, and the legend (if any).
            ar.draw(can)

            return "drawn"

As I wrote in my previous note, the above code executes without any 
errors.  And I get the plain-text "drawn" in my Web browser when I go to 
the /return_basic_chart method via the browser.  But no chart is 
actually generated on disk, so far as I can tell.

If there's a better/smarter way to take PyChart output and display it 
via Zope, I'm all in favor.  And indeed, that's my eventual goal.  But 
right now, I'm concerned that I have a problem whose cause isn't 
obvious, but which might be indicative of something else.

Thanks again,

Reuven

Hi Andy,
thanks for the recommendation!! I did indeed have 4
tables that were MyISAM rather than InnoDB.  So I did
an ALTER TABLE <tablename> TYPE=3Dinnodb; on all of
the tables in question.  However, I'm still getting
these errors in my event log.  Do I need to restart
Zope, the database or refesh anything else ?

also, the reason why I'm interested in this bug is
that every couple of days, after seeing this storage
error msg, Zope hangs, in the log files the hang is
always associated with this error msg:

"AttributeError: Surrogate instance has no attribute
'_p_oid'"

which i figured out is this bug.
http://collector.zope.org/Zope/852, but the resolution
is not clear.  does anyone have any more light to shed
on these ?

thanks a lot,
iroro

Two other things: There is a flag that can be added to the connection
string which manually enables or disables transactions; without flags,
transactions are enabled if supported by the server, i.e. it has
support for InnoDB (and not whether or not your tables are InnoDB,
because it can't detect that).  If you have something like that in
your connection string, remove it; IIRC, it's + or - in front of the
database name. It's a ZMySQLDA extension, so it won't work on other
DAs.

The other one should not affect you: MySQLdb-0.9.2 has issues with
Python-2.2 or newer that affect Zope specifically (the infamous
"server_capabilities" error). Newer versions (1.0 and 1.1 series)
don't have this problem, but you appear to be using Python-2.1.3, so
this should not be an issue. If it were, the product wouldn't work at
all, unless you patched it manually to avoid the check, and since have
forgotten about it.

Please try ZMySQLDA-2.0.9b2 with MySQLdb-1.1.9.

Message-ID: <37125.10.20.1.6.1106789531.squirrel@10.20.1.6>

My plone site died today and I can't get it running again. I have located
the following entries in my logs:

In /var/log/messages:
 zopectl: Unlinking stale socket /var/lob/zope-2.7.2/main/var/zopectlsock;
sleep 1
 zopectl: .

After each restart attempt:

zopectl: daemon process started, pid=xxxx
"14 seconds later"
zopectl: daemon manager not running

event.log:

I'm getting ZODB conflict errors

When the zopectlsock dies it leaves Z2.pid and Z2.lock but no
corresponding process is running.

I've checked around the web and can't find any solutions. Hopefully
someone here can help?

Thanks
Michael

Are you sure Zope is not still running in the background?
Try killall -9 python 
an then restart zope again

Well, as usual when this subject comes up, I felt sufficiently
guilty to spend a couple hours working on my assigned chapter
(Appendix B).
Latest and greatest at 
http://www.plope.com/Books/2_7Edition/AppendixB.stx as usual.

I would really like ZMI access to zope.org, where I hope
the history would help me extract Fred's changes and merge
them with mine. I think I've filled out all the relevant agreements - 
anything missing there?

Hello Johan,

how do you mean that "you must provide a custom layout template".
I think the main problem is to get formulator to generate the field names as
e.g. "record_name.field_name:records:int" and validate it accordingly.

Hello Remy,

thanks for your answer. I'll look into it.

When I tried to open version 0.1.10f with WinZip, I got an error "Error

But I'll have a look at the 0.1.9 version.

Did you make sure you renamed the downloaded file to whatever.tgz 
because "somethign windoze" stupid saved the file with an extension of 
.tar? ;-)

That is odd. Have a loot at Shane Hathaway's VerbosSecurity product to 
see if it can enlighten you...

I'd suggest you contact the product's author direct. I, for one, have 
never even heard on MultiLingualWorkFlow ;-)

Subject: [Zope] How can I searchResults NOT containing a specific path
Message-ID: <41F8CD6D.5080802@finnat.it>

Looking at the documentation, I see that path searches allow me only to 
select items when they HAVE a specific path.

Is there any way to EXCLUDE objects with the specific path (i.e. a 
negate clause)?

Many thanks,

Massimo

Hi I am installing Zope 2.7.4-0. I have installed Python 2.3.4 successfully.

When i run "./configure --prefix=/..."  it finds the optimum version of python and writes the make file. When i then then try to run "make" it gives errors in AccessControl/cAccessControl.c/.... and then exits with the message

"error: command 'gcc' failed with exit status 1
 make: *** [build] Error 1"

Just wondering if anybody could point me in the right direction or what could be causing the problem. Thanks.

Provide the *full* error messages otherwise your posting is pretty much 
worthless.

You should rename the .tar file to .tgz and it will be allright...

I suspect that you have a damaged header file in there somewhere.  You

   - Please verify the MD5 checksum on the Zope-2.7.4-0,tgz tarball
     against the Zope.org product page,
      http://zope.org/Products/Zope/2.7.4/

   - Please unpack the tarball into a temporary location and try
     re-running the configure and make, passing an explicit
     '--with-python' to the Python 2.3.4 installation.

   - If that fails, you could try building your own Python (a good
     idea, anyway), and configuring Zope with it.

   - If things are still broken, please report OS and gcc versions.

This looks like a  broken or incomplete gcc installation. I compiled Zope

Subject: [Zope] Calling a Z SQL Method
Message-ID: <Pine.GSO.4.58.0501271042580.17243@sapphire.engin.umich.edu>

I have a Z SQL method that contains a simple SELECT statement and takes
no arguments. When I call this Z SQL method from a DTML document/method I
use the following: <dtml-in retrieve_names_sql></dtml-in>

This works just fine.

However, when I place the Z SQL method inside a Folder called selects and
then use the following, I get an error:
<dtml-in "selects.retrieve_names_sql"></dtml-in>

The error I get is the following:
KeyError: 0

On the other hand, when I use the following I do not get an error:
<dtml-in "selects.retrieve_names_sql()"></dtml-in>
I understand the difference between the 2 <dtml-in> statements but why
isit that I have to explicitly show that retrieve_names_sql does not take
any arguments in the latter case and not the former. The id of this Z SQL
method/Zope object is retrieve_names_sql and it seems to me that this
should be recognized within the object hierarchy. Any help/input would be
greatly appreciated. Thank you.

<dtml-XXX blah> is equivalent to <dtml-XXX name="blah">
and does some magic tricks to find out if the object
identified by name is callable, and if so how, and then
it is used as ordinary attribute or called via ()
or with some default arguments (REQUEST, Namespace etc)

<dtml-XXX "blah"> and <dtml-XXX expr="blah">
are equivalent also and expect the contents 
beeing a valid python expression, that is, 
you cant simply use . and - in names (since
they have a meaning in python expressions)
and you have to write the call explicit if
you have a method or function. Otoh, this
offers you the way to call the function with
arguments.

A typical startup problem.

Due to a Zope bug (unfortunately not recognized by the maintainers),
startup problems are very difficult to analyse.

If your Zope run in debug mode (no "debug-mode off" in your configuration
file), you can use "zopectl fg" to start it in the foreground.
Then you should see why Zope cannot start on the screen.

I expect that you must tell your canvas that it should write
its content to disk (however, I do not know "Pychart").

There is "ZGDChart". It's a Zope interface to the "GDChart" package.
Maybe, you look at it and how it exposes charts to Zope.

Message-ID: <41F973CB.1050501@simplistix.co.uk>

Hi,

Has anyone else here noticed that with Zope 2.7.x and 
LocalFS-1-3-andreas, when FS-based objects are changes through LocalFS, 
changes are also stored to the ZODB (you'll see a transaction for any 
change made in the Undo tab of the root of your Zope instance) as well?

The changes are made up as follows (from fsdump.py):

   data #00000 oid=000000000000727e class=OFS.Image.Pdata
   data #00001 oid=000000000000727f class=OFS.Image.Pdata
   data #00002 oid=000000000000727c class=OFS.Image.Pdata
   data #00003 oid=000000000000727d class=OFS.Image.Pdata
   data #00004 oid=000000000000727b class=OFS.Image.Pdata
   data #00005 oid=0000000000007282 class=OFS.Image.Pdata
   data #00006 oid=0000000000007283 
class=Products.LocalFS.LocalFS.ObjectWrapper

   data #00007 oid=0000000000007280 class=OFS.Image.Pdata
   data #00008 oid=0000000000007281 class=OFS.Image.Pdata

...and packing removes them.

Does anyone know what's causing this and what could be done to fix it?

cheers,

Chris

Hey Everyone,

Any information I have found related to utilizing PAM for authentication

just not seeing it or the issue was dropped. I'm interested in implementing
PAM for authentication mainly because I ideally need authentication that
draws from a variety of sources including RSA's Authentication Manager. Any
suggestions would be greatly appreciated!

Thanks in Advance,

Subject: [Zope] adding dtml/zpt methods to product classes
Message-ID: <FB0FAC88-70E0-11D9-BC9B-00039372CC72@mac.com>

Greetings Zopistas!

I have been a Zope tinkerer for a few years and have never been able to 
adequately solve this problem:  When I create a Product class with 
DTML/ZPT methods, how can I make those methods members of the class 
rather than simply instance methods?  These examples should illustrate 
what I mean.

My first try was like this:
class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item):
	def __init__(self,resourcePath, imageFolder):
  		self.my_method = Globals.HTMLFile("dtml/my_method",globals())

That works fine until you want to add a new method to your class like 
so:
class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item):
	def __init__(self,resourcePath, imageFolder):
  		self.my_method = Globals.HTMLFile("dtml/my_method",globals())
  		self.my_new_method = Globals.HTMLFile("dtml/my_new_method",globals())

new instances of your product will get the my_new_method, but instances 
that have already been created will not.

My second try was like this:
class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item):
	def my_method(self, REQUEST):
		""" template """
		if (not hasattr(self,"my_method_member")):
			self.my_method_member = Globals.DTMLFile("dtml/my_method",globals())
		return self.my_method_member(self,REQUEST)

This allows me to add methods to the class at any time and all 
instances will get the method.  However, for some reason, when I use 
this pattern, i get strange acquisition results (for example, some of 
my objects children's dtml methods will use the parent's namespace for 
lookups).

Currently, I'm doing this:
class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item):
	def my_method(self, REQUEST):
		""" template """
		self.my_method_member = Globals.DTMLFile("dtml/my_method",globals())
		return self.my_method_member(self,REQUEST)
which seems ugly, and like it might have performance problems, but i 
haven't had any acquisition problems yet.

My real question here is:  What is the standard way to handle this 
problem of being able to add dtml/zpt methods to classes such that all 
instances of those classes get the new methods?

Thanks in advance for any insight.

Sincerely,
Keith Alperin

I feel like I must be misunderstanding the question.
Your examples are so odd, you must be trying to do something
unusual ;-)

But if you're asking what I think you're asking,
just do what nearly ever other zope Product on the planet does:

class Foo(SimpleItem):
    
    my_method1 = DTMLFile('dtml/my_method', globals())

    my_method2 = PageTemplateFile('zpt/my_other_method', globals())

In other words, set them as class attributes, not within
another method.

And to secure them, do this:

class Foo2(SimpleItem):

    security = AccessControl.classSecurityInfo()

    security.declareProtected('Some Permission', 'method1')
    method1 = PageTemplateFile('zpt/method1', globals())

    security.declarePrivate('method2')
    method2 = PageTemplateFile('zpt/method1', globals())

    security.declarePublic('method3')
    method3 = PageTemplateFile('zpt/method3', globals())

Subject: [Zope] Investigating a reference leak...
Message-ID: <HLEGKHKIKMEHENBAEIEPKEMIDBAA.zope@benlast.com>

Dear Zopistas

I've been trying to track down what's either a memory or a reference leak in a Zope 2.7.3 (Python 2.3.4) system.

The symptoms are that after several days of normal running on the agressively proxy-cached production site or a few hours on the
development site under simulated load, the number of OFS.Image.Image references reaches very high levels, such as 17761.  In the
cache at that time are just 4345 images.  There are only 1332 images on the whole site, so assuming (as I understand it) that each
of the 5 Zope thread has its own cache, there should be a maximum of (1332 * threads) = 6660 Images.  The site never creates new
Images, it just loads existing ones.

In a bid to see where these references are being created, I installed LeakFinder, but that doesn't help me because Images are
persistent objects, and thus their __init__ methods are not called (LeakFinder appears to patch just the __init__ and __del__
methods for tracking).  Thus I've been on a quest to find a place to stick a patch that will show me, for a persistent object, from
where a reference to it is being created.

I've tried __setstate__, and overridden it for OFS.Image.Image to print a traceback to stdout.  Then I run the development Zope site
with bin/runzope and watch.  This shows me Images being created in the expected places, but not in quantities that would explain
those huge refcounts.

So; to questions:

1) Is there a better place than __setcache__ to identify where references to Images are being created?  I don't fully understand the
way in which persistent objects are actually created and populated.

2) Our site is very dependent on ExternalMethods (Zope provides the visual layout, business logic is in ExternalMethods, all from
one module).  In some of those methods, the code loads Images in order to look up information about them - this is because we have
some particular standards for things like Image tags which the built-in tag() method can't support, so we have to build our own.
Thus there's code like:

	img = getattr(self.Images,'image.gif')	#all images live in /Images, got by acquisition from self
	buildTag(img.title,img.width,img.height)	#use image attributes to build fuller tag
	del img						#avoid leaving references around (this is paranoid!)

Is there any reason that this is bad practise?  I see __setstate__ for images being called from this code and then again shortly
afterwards when the Image is served up to the browser.

I'd be very grateful for any help on this!

Why don't you simply define the DTML/ZPT objects attributes outside any
class method ?

class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): 
	my_method = Globals.HTMLFile("dtml/my_method",globals())
	my_new_method = Globals.HTMLFile("dtml/my_new_method",globals()) 
	...

This is what I do, and any new DTML/ZPT object I define that way gets added
to any existing instance of this class type when I restart Zope (or when
refresh my product).

class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): 
        def __init__(self,resourcePath, imageFolder): 
               self.my_method = Globals.HTMLFile("dtml/my_method",globals())



That works fine until you want to add a new method to your class like so: class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): 
        def __init__(self,resourcePath, imageFolder): 
               self.my_method = Globals.HTMLFile("dtml/my_method",globals())

               self.my_new_method =
Globals.HTMLFile("dtml/my_new_method",globals()) 


new instances of your product will get the my_new_method, but instances that
have already been created will not. 


My second try was like this: 
class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): 
        def my_method(self, REQUEST): 
                """ template """ 
                if (not hasattr(self,"my_method_member")): 
                        self.my_method_member =
Globals.DTMLFile("dtml/my_method",globals()) 
                return self.my_method_member(self,REQUEST) 


This allows me to add methods to the class at any time and all instances
will get the method. However, for some reason, when I use this pattern, i
get strange acquisition results (for example, some of my objects children's
dtml methods will use the parent's namespace for lookups). 


Currently, I'm doing this: 
class HyperTextArea(Implicit, Globals.Persistent, RoleManager, Item): 
        def my_method(self, REQUEST): 
                """ template """ 
                self.my_method_member =
Globals.DTMLFile("dtml/my_method",globals()) 
                return self.my_method_member(self,REQUEST) 
which seems ugly, and like it might have performance problems, but i haven't
had any acquisition problems yet. 


My real question here is: What is the standard way to handle this problem of
being able to add dtml/zpt methods to classes such that all instances of
those classes get the new methods? 


Thanks in advance for any insight. 


Sincerely, 
Keith Alperin

PluggableAuthenticationService is your friend, you may not even need PAM ;-)

Not sure you mean __setcache__, but this is the kind of question the

Looks like something somewhere is hanging on to references.
You could try the old fashioned way: keep commenting out bits of your 
code in small chunks until the leak goes away, when it does, analyse the 
bit you've just take out to death ;-)

Ouch - I mean "__setstate__" .  I believe the appropriate phrase is "D'oh!"
I'll join zope-dev and see what they have to say.

> > some particular standards for things like Image tags which the built-in tag() method can't support,

Yeah, we're sure.  Our tag handling does stuff like override a GIF with a SWF for the flash version, forces the images to be served
via a dedicated images hostname, etc.  These are external requirements set on us by others...

It's just code that builds up a full <img...> tag using the passed in parameters.  Something I did notice is that, according to the
traceback, __setstate__ is invoked on a line that reads:
	if img:
...which seems odd to me.  Is there any reason that tracebacks through ExternalMethods would dump the wrong line numbers/lines?

Yeah... am sort of doing that by trying single URLs and watching the refcounts.  However, they don't seem to follow any strict
relationship between page templates and increases...

Thanks anyway :)

Hi All,

Well, it was certainly a quiet one. Both Andreas and myself were busy

Special mention must go to brentmh/Crouton who was brave enough to try 
and solve a bug in dtml's sequence stuff:

Brave man!

Anyway, looks like not-having-it-on-a-Friday was major flop, even the

we'll see you all again, last Friday of February!

Subject: [Zope] Is Zope in Use in the law firm sector?
Message-ID: <loom.20050128T113547-560@post.gmane.org>

Hi there

does anyone know of a succesful Zope-Project (especially together with CMF/Plone
or similar CMS) in a major law firm ?

Background: We use a Zope-based CMS for our Website and are also using a small
Plone based Intranet App for our IT Department. At the moment there is a strong
interest in implementing a solution which shall cover Intranet, collaborative
Document Management, eLearning and various "Connectors" to other Systems like
SAP R3 and Lotus Notes. 

Of course there are some hi-class ECMS Systems like Hyperwave which go into that
direction. But these are expensive pieces of software, and I personally would
rather like to see a Zope based solution here.

I know of a few major Zope Projects in Germany, like the ones at Ver.di (largest
trade union in Germany) and TU M?nchen (Technical University of Munich) which
address really large Scale Installations. 

But are there any references about Intranet Solutions for larger law firms with
like 500-1500 Users?

Kind Regards
Maik

Hi

After having tried to get  a couple of commercial apps running without 
success (lack of platform support), I wonder if somebody on the list 
can point me to a product.

I need to build a server cost model for an existing Zope/PostgreSQL 
app, currently running on Solaris/Intel. I want to be able to measure:
- CPU and Memory load of PostgreSQL, Zope and Apache processes
- Disk usage
- Network usage

I am not a UNIX guru, hence I was looking to a commercial solution, 
assuming I'll learn from it. I need to be able to predict requirements 
as usage is increasing.

Any help very appreciated.

Cheers

Marc

Subject: [Zope] [Fwd: TALs Expressions]
Message-ID: <41FA504D.5020007@purdue.edu>

Please explain, I've got this page template, with an empty title.

<h2 tal:condition="template/title">Has a Title</h2>
<h2 tal:condition="template/id">Has an Id</h2>
<h2 tal:condition="template/title | template/id">Has a Title or Id</h2>

The rendered out put is:

<h2>Has an Id</h2>

So...

<h2 tal:condition="template/title">Has a Title</h2>

The tag is omitted because there is no title, which is what I would
expect (empty string evaluates to false).

<h2 tal:condition="template/id">Has an Id</h2>

The tag is included because there is an Id, again what I would expect.

<h2 tal:condition="template/title | template/id">Has a Title or Id</h2>

The tag is omitted (what???) but there is an id, I would expect this to
evaluate to true (false | true == true). (In fact.. anything to the
right of the pipe is not even accessed/called)

Is there something wrong in my thinking?

I'd do this as:
<h2 tal:condition="python:template.title or template.id">Has a Title or Id</h2>
...since the rules for Python expressions are generally easier to understand or clarify with the use of parentheses. :)

After some more searching I found my answer. The pipe is not an OR 
operator in TALs. Instead it separates path expressions and the first 
expression that exists is evaluated.

You understood the question perfectly; this is exactly what i was 
looking for.  I'm not sure where I got the idea of making those methods 
instance variables, but once I started, I never even looked for a 
better (even standard!) alternative.  Thank you (and Pascal Peregrina

Hi,

I've installed  the webmail  product v4.3.1 on zope 2.7  but I can't see 
all the options as described in the readme, I can't see any icons also.
when I call the webmail page at the top of the page I see this:
"Il n y a pas de carnet d adresse,cliquez sur l icone -Contact- pour en 
creer un" but I don't know what it is.
I'm quite new to zope, i find it fantastic.
 
I'm traing to unterstand how can I automatically add the webmail to 
every new registered user, is this possible?
How can I set automatically  the username and the password which the 
user has choosed by registering
in the property of the webmail modul

I'm looking for a good zope programmer for the costruction of a webmail 
portal. Interested people can contact me at javier@callwayonline.de.

This is funny indeed.

When a transaction contains an object's data, then this
means that either

  *  this object was modified

  *  this object was new *AND* is referenced by a modified
     persistent object

  *  this object explicitely was assigned a "_p_oid" and
     was later modified

In the first and second case, one would expect that the
object is still reachable after the transaction.
Thus packing should not remove it.

It is highly unlikely, that LocalFS assigns oids explicitly.
Thus, three should not apply.


Did you show us a complete transaction?
Or are more objects involved?

Subject: [Zope] User-private folderish object
Message-ID: <b5ae713b0501282155760037bc@mail.gmail.com>

Hi All,

A python product I am developing needs a 'user-private' folderish
object.  This seems to be a need that others might have solved but
googling has not turned up any results.

If I have to do this, my first strategy would be to as follows:
Use a __before_publishing_traverse__ hook on my root object to create
a session data object.

Use its onAdd method to create the user-private object in the root object.
Use its onDelete method to destroy the user-private object.

I am assuming that this will cause the owner of the 'user-private'
object to be the person who logged in and that setting its
__ac_roles__ as 'Owner' will limit access to the object to just the
session owner.  (seems a bit complicated, though!)

My question to the Zope cognoscenti is:
Is this a viable strategy? 
Is there a better solution?

I use python 2.3 & Zope 2.7.1
TIA
Rich

Hello,

Perhaps this is a newbie question, but I didn't find something similar in 
the list now.
I want to connect to the ZODB from another applications (something that runs 
on windows,
in this case it should be in MS Access), and read
some data entries which I need for this application.

Is there a ODBC-Diver availabe for the ZODB, that allows one to access the 
ZODB from
another application?

You can of course connect to the ZODB from any Python app, this is 
almost trivial (there are some tips on zope.org and other Zope-related 
sites and lists). I know that Python integrates well with COM, so I 
guess that it could be possible to write a Python COM object to 
interface Access with the ZODB. I've also heard of a Catalog-like (was 
it ZSQLCatalog or like ?) product that allow to run SQL queries on the 
ZODB.

As the ZODB is not a relational (but an object) database
and ODBC is designed for access to relational databases,
the answer is "no".

Seems to be a very indirect way.
Why do you not create the object when you create the user?
Or use the session object directly?

>Use its onDelete method to destroy the user-private object.

Note that this is highly unreliable.
Your session may go away without the "onDelete" method
being called (e.g. when you shut down your Zope server).

"__ac_roles__" has a different purpose (it defines new roles
created at this object).

You must change the permission role mapping.
You can use the "manage_permission" method for this
(source somewhere in the "AccessControl" package).

>My question to the Zope cognoscenti is:

will not work.

>Is there a better solution?

Apparently, you want the lifetime of the "user-private object"
be bound to the lifetime of the session.

In this case, I would simply put it into the session.
This is as safe (and private) as the session itself (which
is not completely but rather safe).

Subject: [Zope] DateTime.strftime problem
Message-ID: <200501300347.03885.rbickers-list-zope2@logicetc.com>

I'm running Zope 2.7.4 and I'm trying to format the current time in the 
format "yyyymmddhhmmssZ" (that is with a timezone of UTC), but I can't do 
it.

The DateTime API says that "A DateTime object's methods return values based 
on the timezone context."  This appares to be the case for all except 
strftime().

For example (my local timezone is US/Eastern):

  now = DateTime('US/Pacific')

  now.pCommonZ()
  Jan. 30, 2005 12:35 am US/Pacific

  now.rfc822()
  Sun, 30 Jan 2005 00:35:58 -0800

  now.strftime('%Y/%m/%d %H:%M:%S %Z')
  2005/01/30 03:35:58 EST

It looks like Collector Bug 1127 (http://zope.org/Collectors/Zope/1127/) 
changed strftime() to always work in the local timezone, instead of always 
working in GMT as it did before.  But shouldn't it respect the timezone of 
the DateTime object as do the other methods?  Is this a bug?

You can put any serializable (picklable) and especially
any persistent object into a session. It looks like:

    obj = <YourConstructor>(...)
    session[<someKey>] = obj

You can later access your object with "session[<someKey>]".

If someone spoofs the session id, it can look into the session
and change it.

With sufficient priviledges, someone can list all session
objects and look into them (and change them).

I yesterday looked at the implementation of "DateTime.strftime" (Zope 2.7.2).
Apparently, it tries to take the timezone into account.

And it works for me:

>>> now=DateTime()
>>> now
DateTime('2005/01/30 19:32:08.823 GMT+1')
>>> now.strftime('%H')
'19'

Subject: [Zope] ZServerSSL deadlocking
Message-ID: <200501301535.15980.dcinege-mlists@psychosis.com>

I'm seeing an issue, that (I'm pretty sure) is limited to ZServerSSL
for m2c 0.13.

I'm using Zope 2.7.4, Python 2.3.4, Linux 2.4.28 and Debian sid. My 
application is an appliance that I use Zope to mainly handle authentication, 
and the content is generated by my external methods, which deal with a mysql 
DB.

Clients are directly connected to the LAN, and the amount of requests doesn't 
really exceed 1 per 3 seconds. All requests (are to) go through https. I 
consider this a fairly light load.

It seems that after a few hours or days of uptime Zope will just cease to 
serve content.  It's sporadic.

Today it happened on a unit at a customers location. I was able to ssh in and 
see it first hand. If I restarted Zope, it MIGHT come back to life. But would 
only serve a few pages and then dead lock again. 

I narrowed it down to SSL as I would restart restart zope, and
  telnet-ssl 127.0.0.1 80
  HEAD / HTTP/1.0

And it would return fine. But the first attempt to the same on port 443 would 
deadlock, and no requests would come back on 80. (I can reconnect to 80, but 
it never replies)  What is REALLY strange is I know if I had rebooted the 
unit it would have went back to normal. But in what ever state things were 
in, by COMPLETELY killing the zope application and restarting it would 
deadlock very quickly upon SSL connect.

After I saw this, I removed the HTTPS section from the zope.conf and allowed 
clients to connect with http. So far, it's seems ZServerSSL is the cause of 
this issue.

Now to make matters worse:
I see nothing in the logs before the deadlock.
No dmesg output.
No syslog output.
Free output looks fine. 
PS output looks fine
I see no active memory leaks

The the very strange thing is if I reboot the unit, it would work fine again, 
for an indeterminable amount of time.

One thought that has come to mind is it's running the random pool dry and 
waiting...but m2crypto draws from /dev/urandom, right? So that shouldn't be an 
issue.

Any ideas?

Have a look at the mappings tab of the VirtualHostMonster you add in the

How can I assign specific permissions to specific users?

Review the permissions for a Manager and see if they are OK for you user.
Is so, give her a Manager's role at login.  Alternatively, you can add a 
special role, say "wheel" and assign appropriate permissions.  Set the 
permissions you want in the security tab at the root of your account.  If
you want them to apply to only a subpart of the site, you can add them at 
an interior node.  If there's only one thing, you may be able to use the
proxy mechanism.

Use the "local roles" facility on the security tab.

Subject: [Zope] Migration of Zope 2.2.3 Installation
Message-ID: <200501310043.02496.segedunum@actuaria.co.uk>

Hi All,

I've got a server that is running Zope 2.2.3 (currently using Python 1.5) that 
I need to migrate, and I'd appreciate some advice.

Given some cyclic dependencies on this system we can't upgrade Zope straight 
away, but we need to upgrade the rest of the system which indirectly entails 
updating to Python 2.4 which is unavoidable. Does Zope 2.2.3 depend tightly 
on Python 1.5, or could it run under 2.4? If not I'll have to think about 
some kind of slotted install and move over.

Just wondering if there any issues people have encountered in upgrading pretty 
old Zope servers that may be helpful, such as migrating the Data.fs (this is 
pretty large).

Thanks,

David

Even *current* stable releases of Zope are not officially supported
for python 2.4.

Your zope start scripts should specify which version of python they
use, and there is no reason not to have multiple versions of
python installed.

Dunno about your upgrade process per se, it's been so long since
I've even *seen* a zope 2.2 system :-)
But I would NOT try to run it on anything other than python 1.5.

What do you get when you try my examples?  You only used your local timezone, 
which works fine for me too, but it doesn't work when I'm trying to use a 
different timezone than my own.

Also, according to notes in the bug I referenced, it looks like the behavior 
may have changed starting with 2.7.4.

Subject: [Zope] KeyError with everything
Message-ID: <a8f71ef4bbcc9e69ee97d2e524ff0041@mac.com>

Hi,  I wondered if anyone could help me on this issue that is driving 
me nuts.  I'm new to zope, and google has been fruitless on this.

I have installed Zope 2.7, Plone 2.0.5, and have Python 2.4 on.  Not 
supported, I know, but I needed 2.4 for something else, so figured I'd 
try it.

Anyway, I have it all up and running fine, but some Products won't 
install.  E.g.  SimpleBlog, CMFBoard, and ArchExample.  Well, okay, 
they will install, and zope will start, but they all have the same 
symptoms.  Whenever I add a blog, forum, or article from them, I get a 
KeyError, on field 'zid'.  With ArchExample, it actually says "I can't 
find this file", but I know it means the same error (I hope).

I've also tried creating my own class in ArgoUML, ArchGenXML'ing it, 
and I get the same with that too.  Even if I create the simplest of 
classes.

Wha could be wrong here?  Give me hints and I'll dig deeper, it's just 
that I can't find anything on google at all  :-/

Thanks,
Jamie

Ok. Looking into time.strftime(), I can see the difficulty in making this 
work as expected, but I found a way to get what I want.  Don't know why I 
didn't think of it before.

  utc = DateTime('UTC')
  "%4d%02d%02d%02d%02d%02dZ" % utc.parts()[:6]

Not as pretty, but it works.  I guess one can always roll their own strftime 
with string formatting and all the other DateTime methods.

If strftime() is always going to return the time in the local timezone, I 
suggest it be documented in the API since it's inconsistent with the other 
methods.

Thanks!

If you think that this is a bug: file a collector issue preferred with a 
patch and unittests if you want to see this
fixed in the next releases.

Hi i am setting up apache to work with Zope. I am using the documentation at

http://plone.org/documentation/howto/plone-with-apache-1.3/view?searchterm=plone%20with%20apache

I have istalled the Virtual host monster ok but my question is reguards the piece of code

<VirtualHost *>
ServerName me.com
ServerAlias www.me.com
ServerAdmin webmaster@me.com
ProxyPass / http://localhost:8080/VirtualHostBase/http/me.com:80/mysite/VirtualHostRoot/
ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/me.com:80/mysite/VirtualHostRoot/
</VirtualHost>

I was wondering if you simply add this to your httpd.conf file or do you replace what is already there with this?

Thanks for any help.
Neil

Well, it looks like you are trying to import an object but Zope can not find
the file in it's "Import" directory.
(by default, objects get exported to the "var" directory, so you then have
to move them to the "Import" directory to import them back)

That's really your choice how  to organize your configuration. If you want 
it modular
then create a dedicated  config file and include it into the main 
httpd.conf or put everything
together in one place.....a decision that you must make...

You already answered the question : Zope 2.7.x does not run on Python 
2.4.x.

Note that nothing prevents you from having two Python versions on the 
same system.

I think that depends on whether you're maintaining the Zope server that

Yes, but remember what LocalFS is doing is trying to spoof Zope into 
believing objects come from within the ZODB, while actually storing them 
on the file system.
I have a hunch that it probably mixes OFS.Image.File into its "File" 
objects, and OFS.Image.File is doing something naughty (it usually does, 
it's got some VERY esoteric code in it ;-) which results in data being 
comitted to the ZODB. However, since LocalFS manages to not store any 
data in the ZODB, the stuff OFS.Image.File causes to get comitted 
probably gets packed away...

Sound plausible? I'm still keen to hear of anyone else who can reproduce 
this...

> Did you show us a complete transaction?

Yep, pretty sure I did.

Nope. All data in this project is supposed to be stored either in Oracle 
or on the file system (accessed through LocalFS).

Okay, but what am I looking for?

"registered user" sounds like you might be dealing with CMF or Plone, is 
that the case?

Zope 3 has it's own PAS implementation. There is also a PAS product for 
Zope 2.

You should probably ask about that on the mailing lists. 2.6.x is 
somewhat fossilized now and ther are many features in the 2.7 series 
that make it well worthwhile upgrading...

Subject: [Zope] Acquisition - I don't get it
Message-ID: <41FE436B.3010604@bruvoll.com>

Hi there,

I've been struggling with something that must be very basic, but I just 
don't get it. Hopefully, there's somebody out there who could enlighten 
me a little...

I have this site hierarchy, something like this:

/top
/top/section1/
/top/section1/chapter1
/top/section1/chapter1/paragraph1
/top/section1/chapter1/paragraph2
/top/section1/chapter2
/top/section1/chapter2/paragraph1
/top/section2/
/top/section2/chapter1
/top/section2/chapter1/paragraph1

etc.

These are all folders with an index_html inside them. The template will 
have, among other things, a site title image, a section title image, and 
a page title image for each page.

The idea here is to be able to create a folder img/ at appropriate 
levels of this hierarchy and use images section_title.gif, 
chapter_title.gif, page_title.gif, etc. This might be where I've 
misunderstood everything, but I was hoping to do something like this:

<img src="dummy.gif" class="title-img" tal:define="image 
here/img/section_title.gif" tal:attributes="src image/absolute_url" />

If for instance looking at one of the paragraph pages, the template 
would then, in my perfect world, start looking for an "img/" folder at 
the current level, and within it a file named "section_title.gif", and 
if it does not find it, it will try again one level up in the hierarchy, 
until it then finds the section_title.gif in the folder 
/top/section1/img/section_title.gif. Same goes for the other images, but 
they would "hit" further down in the hierarchy so that I could 
effectively let a "closer" image override one with the same name, but 
further up.

Have I got it completely wrong? Is my thinking right, but my syntax 
wrong? Haven't been able to get anywhere on this - all documentation I 
can find gives hints and pointers, but I'm still stuck...

Any help & comments highly appreciated!

Best regards
Jan

Each element of the path is acquired in turn, and acquisition doesn't
backtrack when something cannot be found.

So in this case, it starts at the current level and looks for "img", and
finds it. So far so good! Then, it starts from that img folder and looks
for your image "section_title.gif". It's not here! So, acquisition will
move on to search the parent of the img folder, and the parent of that,
and so on. Your section title image can't be found anywhere! Result: Not
found. At no point will the process backtrack and try other possible "img"
folders - when you say "img", you get the first one that can be acquired,
and then that's that.

To acquire images in the way you describe, you would need to do away with
your "img" folders, and include the images directly in each folder in your
hierarchy.

Thanks,
Malcolm.

Hi Malcolm,

thanks for your very quick reply.

So - if I want to do it "my way", I'd have to write a quick python 
method that does the searching for me, I presume.

However, I already tried doing away with the folders and putting those 
images directly into the folders, so that there are images across the 
site like this:

/top
/top/site-title.gif
/top/section1/
/top/section1/section-title.gif
/top/section1/chapter1
/top/section1/chapter1/page-title.gif
/top/section1/chapter1/paragraph1
/top/section1/chapter1/paragraph1/page-title.gif
...

It works in those folders where the relevant images actually are, but the traversal does not kick in. Any pointers to this as well maybe?

Thanks again

Best regards
Jan

Hi again,

forget it - I'm just being daft. Of course it works - had just moved the 
images around a little too much in my desperation.

Thanks for the update on the way the traversal works - everything's a 
little clearer now!

Best regards

Message-ID: <20050131161806.ADB271E4B0@xprdmailfe24.nwk.excite.com>


I have tried simply adding the code to my httpd.conf file but unfortunatly it hasn't worked. I have included my httpd.conf file below. I am sure mod_proxy is installed and working fine. It is called although not listed below. I took it out in this email to make it appear better. 

My main question is reguarding the 2 lines 
ProxyPass / http://localhost:8080/VirtualHostBase/http/sample.com:80/website/VirtualHostRoot/
ProxyPassReverse / http://localhost:8080/VirtualHostBase/http/sample.com:80/mysite/VirtualHostRoot/

what value does "mysite" represent? Is it where my folder is located on the file system or simply the name of mysite?

There is a HowTo how to analyse such situations.
Search for "debugging spinning Zope" (or similar).
I think the approach will work when you are on *nix
(or have a debugger that is able to attach to a running process).

One of the first things, you should learn:

  Whenever you see an "*Error" (such as "KeyError", "NameError",
  "AttributeError", ...), look at the traceback.

  You find it in your "error_log" object, situated in your
  Zope "Root Folder" (in the Management Interface).

  When you report errors, include at least:
  "ErrorType", "ErrorValue" and the traceback (all from the
  "error_log").

The best way is not to try to intercept the "logon"
but to create the "user-private" object the first time it is needed.

'18'

Note, that my local timezone is "GMT+1".

Thus, it works for me also in a different timezone.

Okay, can only speak for 2.7.2.

I do not think that "LocalFS" is in any way interested to simulate
objects in the ZODB. Instead, it emulates a hierarchy apparently rooted
in a ZODB based object. But this is purely an acquisition concept and
completely independent from the ZODB.

Indeed, it contains a subtransaction commit.

However, this should only lead to true ZODB writes when
the object either already was persistent or is new
and part of a modified persistent object.

In the current transaction (obtained via "get_transaction()"
for "_objects". You are interested in the code
that adds objects to "_objects". The first object
added to "_objects" is the persistent object that should
not have become modified.

2.7.3 gives the same thing you're reporting, but 2.7.4 does not.

What does DateTime('GMT').strftime('%Z') return for you?  Both 2.7.3 and 
2.7.4 return my local timezone, even though 2.7.3 returns the correct hour 
for GMT.

No, the docs say that it is not supported, but they don't assure that
it won't run. Perhaps the problem isn't related to python at all, but
it is dificult to say it without a traceback.

if you look at the LocalFS code (I have but not recently), 
it actually creates a temporary instance of e.g. OFS.Image.File 
on every request for a "file". IIRC these are supposed to 
be thrown away, but apparently something is broken...

Hi,

I found the file manage_page_style.css.dtml (among
other style sheets) under <Zope installation
dir>/lib/python/App/dtml which I suspect is the same
when I type /manage_page_style.css in the browser.

Is there somewhere in the documentation that says the
connection / convention between the stylesheet and its
location. When I go to the root and try to use the
find facility to look for eg. manage_page_style.css,
it couldn't find it.

Thanks for your answer.

Hello,

I am trying to find a way to pass data from a java applet into zope.
Don't know how to get the serialized object into the zope python script.

With html forms I'd just use container.REQUEST, but it doesn't work in this

Any help is appreciated.

Subject: [Zope] InvokeFactory Question
Message-ID: <BAC1BDE9-73F4-11D9-A309-000A27B3B070@eastlink.ca>

Hi. I have written a small Script Python to create a Portal Folder in a 
specific Folder (root/information) using a form.  This creates the 
Portal Folder I want but instead of creating it in the information 
folder, I find it in the root folder.  Can someone point out what I am 
doing wrong.  If I use getId() on  info_dir it gives me 'information'  
as the id so it appears I am creating it with the right object. I have 
manager proxy on the Script Python as well.

Regards,
David

# Get portal url object
url_tool = getToolByName(context, 'portal_url')
# Get the path from the object
portal_path = url_tool.getPortalPath()
# Information directory (Folder) object
info_dir = context.restrictedTraverse('%s/information' % portal_path)
# Cancel button action
if form_cancel is not None:
	RESPONSE.redirect('index_html?start:int=%s&sort=%s&reverse:int=%s' 
%(start, sort, reverse))
	return None
# Save button action
if form_save is not None:
	category_id = context.cleanId(category_id)
	# Create a Portal Folder object
	info_dir.invokeFactory('Folder', category_id)
	# Get a handle on the new object created
	folder_obj = getattr(info_dir, category_id)
	# Get and fill the fields
	folder_obj.setTitle(title)
	folder_obj.setDescription(description)
	RESPONSE.redirect('index_html?start:int=%s&sort=%s&reverse:int=%s' 
%(start, sort, reverse))
	return None

The Zope path to the object you want to use as the base. In my case I
have things like:
RewriteRule ^/(.*)
http://localhost:8080/VirtualHostBase/http/wishlists.sitharus.com:80/wishlists/VirtualHostRoot/$1
to serve /wishlists/ on my Zope instance as
http://wishlists.sitharus.com/'s main site.

No there isn't, I've just realised that I should perhaps re-name the 
variables so the one in the request is not used in a ZSQL method but the 
correct one is.
