[Albert] Congratulations!!!
Two questions:
1. Any guesstimate (vague upper and lower bounds) on first beta release for the binaries, (or even just a vague lower bound - "probably not before ...")?
2. In the Migration Guide:
"A note to component developers - as of Zope 2.4 ExtensionClass has not been updated to support all of the new "magic protocols" that Python classes support (we're hoping that EC will go away soon)."
What does "hoping that EC will go away soon" mean? I thought that ExtensionClass was pretty fundamental to Zope?? Does this just mean that the limitation on "magic protocols" will go away soon, or is there some URL I should look at re replacement for EC?
Thanks, and congratulations again.

EC are a fix for a problem that shouldn't exist in Python (inability to inherit from classes defined in C/C++).
By "hoping that EC will go away soon", I assume they mean the PythonLabs folks are working on fixing this for once in Python itself. Right?

That is correct. The point is, ExtensionClass machinery will go away but the functionality would remain, if Python changes in the future to make it unnecessary.

- New restricted execution architecture
A note about this for those who have run afoul of restrictions on builtins such as 'list', 'map', and 'range' in Scripts and DTML Python expressions:
In the new architecture, there are (by default) no attempts to protect the system against excessive CPU or memory utilization. Unless you explicitly turn on such limits (not implemented yet), anyone who has permission to write DTML or Scripts in your Zope can accidentally or deliberately consume all available resources with infinite loops or huge data structures. Realistically, they could before, they just had to be slightly more creative.
Cheers,
Evan @ digicool
Hi Brian, hi all,
great to hear this.
Now comes a tricky question:
Suppose we are running a Linux Kernel 2.4.x and using the latest Python 2.x distribution. And supposing we can recompile all code if neccessary:
How large can a Data.fs grow until it breaks ? We need to be able to store about 7.5 GBytes (note: Gigabytes) in the ZODB. I would rather use the ZODB than a LocalFS ....
Thanks in advance - Holger

Cool stuff.
I have a couple of comments, though. For future ref., should I post them to the Collector?
- lib/python/Products/PluginIndexes/__init__.py is missing the ZPL
- why is Catalog.gif in Products/ZCatalog and not in Products/ZCatalog/www like ZCatalog.gif?
- the version.txt in lib/python/ says: Zope 2.4.0a1 (source release, python 1.5.2, linux2) which sounds a bit funny in my ears... Might be me, I dunno.
The biggest one is the fact that I can't build it, but I think that's a problem with my Python installation.
Once I've got it up and running I might do some actual testing, which I'm looking forward to! :)

Actually I have wondered something about that... Why does it always show up as linux2 even when not on linux? I'm on FreeBSD using a compiled from source python and Zope and it still shows up as Linux.

lib/python/version.txt
Just edit it.

This smells like a bug to me. If the software is compiled from source, I expect it to tell me what system/software it was *actually* compiled with, and in the case of python *actually* running on, not some string hardcoded into a text file. If the string is not dynamically generated, I'd rather it not lie; ie: it should just give the Zope version.
