I know that. I was responding to the mistaken assertion that external
methods have no security at all. They have much more security than
python scripts.

Subject: [Zope] ange-ftp to zope 8021 in emacs 21


Is anyone having success with ange-ftp in emacs 21 using the zope ftp
server?  It worked fine for me in emacs 20.7, but in 21.2, when I try
save-buffer, I get the error:

  byte-code: Keyboard macro terminated by a command ringing the bell

I have successfully edited and saved files via ange-ftp with other ftp
servers, so it seems to be some combination of the recent version of
ange-ftp/emacs with the zope ftp server (and perhaps others).

I posted to gnu.emacs.bug, but am wondering if anyone else has
encountered success or failure with this combination, and more
important, has any suggestions for how to fix it.

Thanks,
John Hunter

excellent, that helps a lot :)

The ZMI view of the script gives errors and warnings, without even 
having to test the script. This is very useful, although the messages 
don't give you line numbers, which would have been excellent.

I'd been using ExternalEditor, so didn't see the messages when saving in 
the ZMI.

(to anyone that uses the ZMI through a windows-based browser: using 
ExternalEditor and Gvim is fantastic - colour syntax highlighting modes 
for DTML and Python :)

It's interesting that it works on your platform, which is very close
to mine.  I launched emacs with 
 > /usr/local/bin/emacs-21.2 -q --no-site-file

so I don't think it's one of my keyboard macros.  And I checked the
binding of C-x C-s to make sure it was running save-buffer.  I'm not
the first to bump into this problem:

http://groups.google.com/groups?hl=en&lr=&ie=ISO-8859-1&q=byte-code%3A+Keybo
ard+macro+terminated+by+a+command+ringing+the+bell&btnG=Google+Search

but I haven't found the solution yet.  I wonder what could explain the
differences in your platform and mine.  The emacs version numbers are
identical; the only difference in the zope version numbers is that I
have Zope 2.5.1b1 and you have Zope 2.5.1.  We're bit running python
2.1.3 on linux.  Weird.

Subject: [Zope] URLs, objects, and <dtml-

I am pretty sure there are some clever techniques I have missed.

When I first started using Zope accessing objects at different places in
the object hiearchy was a problem.  I found some workarounds and learned
to cope, but I am now revisiting the issue.

For specificity, consider the following folder hiearchy:

R
   A1
       B1
	  D1
       C1
   A2
       B2
       C2
          D2

URLs would reference the somepage object in  D2 using the 
URL R/A2/C2/D2/somepage.    


Now, DTML, for example, <dtml-var >, specifies an object which is located
the current namespace by one of a variety of rules including acqusition.

Control over the namespace is provided using <dtml-with> but using it can
be cumbersome.  To reference an object in the folder D2 from D1 would
require wrapping the referencing <dtml-var> in a next of <dtml-with>
statements which make the namespace of A2, C2, and D2 available.  For a
site with a deep and complicated hiearchy, this is a mess. Hard to write,
hard to maintain, and very error prone.  The tendancy is to make all
scripts look like central mechanism wrapped in multiple with's to setup
the right namespace.

A better approach might be to access all nonlocal objects through a Python
Script that traverses a URL parameter and returns the specified object.
In this case, referencing the object foo in D2 above would be accomplished
by

  <dtml-var name="traverse_to_object('R/A2/C2/D2/foo')">

and so forth.  

This should work, but it kneecaps Zopes namespace management features
because 
it returns an object, not a name to be resolved to an object in context
through
bobo_traverse, acqusition, and so forth.

So, finally, the question:  How does one manage in an efficient and
compact fashion accesses to objects stored outside of the acquisition
path?


There are a couple of other notational issues that are a bit confusing.
If I have a folder (call it scripts) at my site root, I can reference 
the individual scripts by the names 'scripts.script1()'.  When does 
this notation extend to objects stored in nested folders?

One the defining notions of Zope is the equivalence of a page as specified
by a URL and an object.  What's the reason that something like 

   <dtml-var name="R/A2/C2/D2/foo">

does not resolve to the name foo in the container reachable by traversing
"R/A2/C2/D2" when accessed from within Zope.  It does work from the Web.

A badly written regex can easily run in an infinite loop, hanging a thread
of
your Zope server. Once the number of people who cause this regex to execute
is
equal to the number of threads on your Zope server, you have a hung server
;-)

Thats working: In z2.py set

LOCALE_ID=3D"cz"

for ISO-8859-2.

I dont know scandinavian charset (iso-8859-1?), but you should be inspire=

with linux/unix locales. Eg., for czech lang is locale cs_CZ, but under

You can, more or less. DTML will disregard unknown tags, as will most HTML
rendering engines (XML is another matter).

So go ahead and changed <dtml-if> to <xdtml-if> and watch it get ignored.
Note that this is not a true dtml-comment, as the code between tags will
still appear in your output, but it's a handy trick for finding logic
problems.

But I would like to have a smaller alias for dtml-comment, too. Truthfully,
what I would really like is a 'Comments' tab in the ZMI for every object
allowing me to store adminstrative docs in the objects. And it would be
really great if I had a chocolate ice cream cone right about now,
preferrably in a waffle cone.

When you see this, try looking at the console Zope is running in or in your
STUPID_LOG_FILE, the exact nature of the error is usually reported there...

Subject: [Zope] How to get name of calling DTML or script..

I have a python script which needs to redirect the browser to the page that

I call a script named "blah", I want the blah script to do the following
(among other things):

...
context.request.RESPONSE.redirect(x)


where x is the name or URL of the page that called the script.  Make sense?
Any ideas?

That will call sequence-item if it is callable, which is often not what you

Subject: [Zope] New MySQLdb/ZMySQLDA releases pending

The (hopefully) final release candidate for MySQL-python (MySQLdb) is
out:

	http://sourceforge.net/project/showfiles.php?group_id=22307

(mysql-python-test 0.9.2c3)

ZMySQLDA is still on 2.0.9b2. That seemed to help prevent some crashing
problems, although it seemed a lot of those crashes were fixed by
Python-2.1.3. So I'd like some feedback on this: Did you try
ZMySQLDA-2.0.9b2 to fix problems that you were having with 2.0.8? If so,
what was the effect?

Zope notes: MySQLdb-0.9.2 plays nicely with Python-2.2.1; not sure if
2.6 is targeting Python-2.2 or 2.1. If you are using Python-2.2 or
newer, _mysql.connection and .result are sub-classable types. There's
also more support for Unicode now; not sure what the current SOTA is for
Unicode in Zope. ZMySQLDA doesn't do anything with Unicode currently,
but could very easily.

bzzzt...right.  The original poster was asking about reserved words used
with standard dtml-xx statements, like sequence-item, and it is right for
them though not in general (as you said).

Take a look at the contents of the REQUEST object.  You'll probably find 
what you need there :-)

To view the REQUEST Object contents, make a Python Script 

request = container.REQUEST
for k in request.keys():
   print k, '=', request[k]
print
return printed

I have been running  ZMySQLDA-2.0.8 and MySQL-python-0.9.1 in 
a RH7.3 configuration with Zope 2.5.1 without any problems.
Traffic is still low as we are in development not live.

I'll probably upgrade to 0.9.2b2 or later sometime soon.

Greetings Matt, and zope crew!

I just installed 2.5.1 and the same thing happened...  After about 4-6 
hours zope just stops.

Any other ideas as to how to start troubleshooting this?  Is this a system 
issue, or a zope issue?

One thing I notice that might be affecting it is that for some reason 
after starting zope in my terminal window with "./start &" I am unable to 
properly disconnect from the server.  I have to close the window, and 
me ssh client asks me if I want to disconnect.

Could this be affecting it?

Cc: zope@zope.org

That seems to be the answer. However I tried Charlie's suggestions and 
made the data members as lists (not strings as he suggested, seemed to 
work equally well and I didnt have to switch back and forth between 
functions calls) instead of arrrays and only instantiated arrays where I 
needed to use them (only inside of functions) as local variables.

Well it doesnt work. Everytime that function (that has an array 
declaration inside) is called I get another UnpickleableError.
I am at my wit's end... how do I get around it or force it through...

any help would greatly appreciated.

one function that raises that error:
 
def _reverse_hex(self,s):
        x=array.array('c',s) ## causes the error .... no problems if I 
remove it
        for i in range(0,len(s),4):
            a=x[i]
            b=x[i+1]
            c=x[i+2]
            d=x[i+3]

            x[i]=c

Two suggestions come to mind but I doubt either will help.

1) Change your last line to:
  # Clean up.
  y=x.tostring()
  x=None
  return y

2) Rename 'x' to something longer. If you have a module variable named x,
the array will stick around after returning. It still shouldn't be
serialized, as it isn't part of your object, but I don't really have any
other suggestions.

Neither of these should matter but it's worth a shot.

Also, double check your indentation on the for loop. Make sure that return
is not inside the loop. That shouldn't matter either though...

Oh, wait, one more suggestion. Don't write this as a method. Stick it in a
python script or an external method. Your class should not even import array
that way.

Subject: [Zope] Groupware - worldpilot

Hi all,

just tested again Worldpilot and got it to work with Zope 2.5.1 and 
python 2.1.3. Only one adjustment had to be made to WPUtils.py. ( See 
end of message ). Now my question is:

- Is there anyone using worldpilot?
- Is there anyone developing it anymore?
- Would someone be interested to continue developing it onward and 
possibly make it more zopish, and or make it as a CMF-product?

What else pieces you people use as a products for groupware? For 
email, calendar etc. ? Are there any good Zope-products that could be 
used in combination better?

I'm been building our intranet with CMF and only things now missiong 
is just the PIM functionality. Calendar and webmail are php programs 
as well as the meeting room booking system. Now if there were great 
components to do all this again in Zope it would be great...


Adjustent was to:

import imaplib
was: from imaplib import *

and to:

mon = imaplib.Mon2num[mo.group('mon')]
was: mon = Mon2num[mo.group('mon')]

oops, I didn't mention that the DTML method which wants to access this 
attribute is called from the inside of a instance of my GoogleWebAPI
Product, 
which in turn is called from a form in a DTML document:

<dtml-var "google.doGoogleSearch( zzz, render_method 
= 'doGoogleSearch_html' )">

and in 'doGoogleSearch_html' is:

<dtml-var "REQUEST.zzz">

/hd

Perhaps I'm wrong, but I think that ZSession keep sessions properties in
memory, and don't store them in ZODB.
These sessions are cleared from memory after a given timeout (20 minutes
by default).

Should that be enough to prevent me from the problem you specify above
??

..most of the time..

HTTP_REFERER is an *optional* HTTP-HEADER that most clients/browsers
send with the request , but they are not required to do so. I know
that at least in Opera there is an option to turn it off for those
concerned with privacy..

- Just so that no one relies on it for important stuff...

Subject: [Zope] I don't want WebDav

Hi,

Is there a way to disable WebDav when downloading word documents? I have a
script that generates a word document and lets the user then view it/save
it. However, when I serve the document, MsWord and Zope will find that they
can communicate through WebDAV and Word will (sometimes) offer the user to
save the document on Zope, which won't work because it is generated.

remember to check what port you are connecting to, as you can't use 
the same port as what zope uses to serve. i.e. if we have a site 
running off port 11000, we webdav to 11001.

we have webdav connecting on win2k and it works fine. don't get me 
started on mac os 10.1 and its webdav implementation...

oh all right then! we had problems with copying a file (using 
webdav) to the machines hard disc, doing an edit (in bbedit), then 
copying it back. the file was a dtml method, but when it copies 
back it becomes a standard file -- it looses its zope-ness. this 
was using the built in mac 10.1 webdav. if we use goliath (a mac 
webdav client which is free from www.webdav.org), it works! sort it 
out apple!!

Subject: [Zope] Zope+Photo Product

Hello everybody,
I have installed Zope and Photo Product.I have CMF installed in zope.
Photo requires ImageMagick,which i had installed.
I am using Linux OS.
I am using Photo Product inside CMF Site.
Through 'Manager' Role i am able to upload a photo.
But i am not quite sure as to how to use this Photo product.
Lets say,I want to build an Image Galary with 'Manager' Role, then how will
i let 'Member' User see it.
If there is some example of building Photo gallary,please let me know.

Thanking you in advance,

Hmm, not quite. it stores the sub-objects in the folder's __dict__. It do=

BTreeFolder was definitely a huge advantage before Zope 2.6, because the =
old=20
ZODB cache did not cope well with the fact that the __dict__ loaded all=20
40,000 sub-objects into memory as ghosts.

Zope 2.6 has a different cache manager that does not panic when it is giv=

BTreeFolder is saving you 4M of ram (per worker thread). Not bad, but may=

BTreeFolder has a problem that it doesnt store *all* of its data in the B=

It still has the tuple caching id and meta-type, thanks to it ObjectManag=

CMFPhoto, http://www.zope.org/Members/magnus/CMFPhoto is a CMF wrapper 
object for the Photo product. The included skins are for plone, but 
there is nothing stopping you from writing own skins for it.

CMFPhoto is now hosted at CMF Collective, 
http://sourceforge.net/projects/collective/, where I am in the process 
of rewriting the whole thing. The new CMFPhoto is based on 
CMFDefault.Image, and does not use the Photo product. Scaled images are 
stored in a OOBTree.

It still uses ImageMagick. New feature include image rotation and 
slideshow. I plan enable more. (you can do quite a but with imagemagick).

You can get current shapshot from here; 
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/collective/CMFPhoto/

It's a moving target at the moment, but it's working. The skins need a 
bit of refactoring before they are finnished.

I plan to release it within the next days. The included skin is for plone.

Hello All,

I am using Zope 2-5-1 and CMF-1.2.

I am trying to use python:path in a html form to get a path name which I
will pass to a python script and use the setDescription function on.  I am
not getting the python:path statement to work.  If I print my python:path
statement into a table header I get something like:  "<PortalFolder
instance at 90a24a0>"   What I am doing wrong?  I have pasted portions of
my code below.  I also attempted to use 'nocall' but didn't get that to
work for me either.

Thanks in advance!


<table tal:define="myhere root/MyPortal/folderA">
<tr valign="top" align="left"
     tal:repeat="folders python:myhere.contentValues(filter
={'Type':'Folder'})">
<span tal:define="folderID folders/id">
<th tal:content="folders/title">Title</th>
<td><input type="radio" name="folderTitle"
     value="folders"
     tal:attributes="value folders/title"></td>

<td><input type="hidden" name="folderPath"
    value="folderPath"

Then in the python script:
folderPath.setDescription("This is my new description")

Somebody use XForms here?

Subject: [Zope] dtml-let

Hi,

I'm trying to output a table using dtml-in, that shows a certain number of
rows in that table, then adds up the rows not shown, and shows an "other
values" row, and finally shows totals for all the data in the table.

So the output would be something like this:

Language  Requests  Uniques Sessions     Percent     Time to Load
   it     92384     293       231         56.1%          3.0   
   fr     51563     65487     21          31.3%          1.0
   de     9834      9648       521         6.0%          3.2

[Other] 1   5416     25163     31          3.3%          0.0   
Total:     164653     101245     354935    100%          1.44


The dtml I'd like to use would be something like this:

dtml-let "set all variables to zero"
   dtml-in the request
       dtml-if sequence-number <= floor
           output a row with data
       dtml-else
           dtml-let "add up "other values" data using variables set at
top"
       dtml-if sequence-end
           output "other values" row
           output "totals" row
       /dtml-let 
   /dtml-in
/dtml-let

But dtml-let is zeroing the variables each iteration. Is there a better
way to do what I'm trying to do?

Thanks,

Ale

Subject: [Zope] Interesting RE problem

Whether or not allowing the re module is safe, I added it

to our test server.  I notice an interesting 'bug?' however

(more likely user error).

I created a simple PythonScript object inside of a TestProduct,

where the PythonScript is the view of the TestProduct(inherits

from DTMLMethod). When I create an instance of my Test object

and save it, then click on the View tab, I get an:

> Unauthorized to access compile in this context error (re.compile(str))

HOWEVER, if I open a new browser window and type in the URL of the

object with no auth (normal web user), it renders fine, without error.

Any enlightenment?

I've been updating BTreeFolder lately.  The latest code is called 
BTreeFolder2, though the reason I changed the name is now gone and I may 
decide to rename it back to BTreeFolder.  It's available at cvs.zope.org 
under /Products.

The newest code stores *all* subobject data in BTrees; no more giant 
tuple.  That giant tuple turned out to be a bit of a problem for very 
large folders, since every time you add or remove an item, a new 
multi-megabyte pickle is generated, transferred, and appended to a file. 
   That problem is gone now.  The newest code also features unit tests, 
a CMF-friendly version, conflict prevention, and a unique ID generation 
utility.

BTreeFolder is useful where you need something like a big dictionary 
that rarely gets exposed to the user, but you want it to remain 
discoverable and easily manipulated in emergencies.  It doesn't always 
take the place of something customized, but it's definitely more 
scalable than ever.

Shane

It can be disabled in general by using the -W flag (according to the
zope-z2.py I have here)

Adding the flag of "-W -" should disable it. "-W portnumber" would put
WebDAV on portnumber. I don't know of any way to disable it
specifically for Word, though.

I'm not sure about the difference between using test and calling the
method through the web, but this is an example of why the re module
hasn't been considered for inclusion in the default TTW-importable
module list.  Someone will need to wrap the re module to return
things that can be protected with security declarations if it's ever
to be included as a TTW-accessible module.
