Summary: Python 2.2.2b1 + ZODB 1.0 Error - WinXP
Initial Comment:
Python 2.2.2b1 with "StandAlone ZODB 1.0" (latest
release) works on Solaris. (I suspect on most Unixes)
I downloaded Python 2.2.2b1 and built ZODB with
MSVC 7.0 on Windows XP Pro.
The tests ran fine for a while, and I got some errors in
lock_file.py (file is possibly locked by another process).
After a few such messages the test.py process hung.
Later, I tried the StorageServer.py. Worked on Solaris
2.8 (gcc 3.0.4).
Failed on Windows with the lock_file error above.
I commented out the "raise" in the file, then the process
started up. When I tried using the ZODB.ClientStorage,
the client process hung.
ZODB does not work at all with Python 2.2.1
(unpatched) - get a crash, but that's probably to the
ExtensionClass bug.
Thanks for producing these amazing tools such as
Python, ZODB etc. I don't use Perl anymore.

The .pyd files DO exist.
Anyway, I will try to build Python 2.2.2b1 from scratch and
run it in the debugger. Don't hope to find much as I am not
familiar with the ZODB/Python C source code.

Do you have a cPersistence.pyd file? When I build ZODB3 on
Windows (MSVC 6), I get
buil\lib.win32-2.2\ZODB\cPersistence.pyd.
Note that the test.py script runs out of the build
directory, not the source directory. If you run Python from
the same directory as test.py, it will try to run from the
source directory and fail. You need to put the build\lib
directory on PYTHONPATH.

Actually:

ZIP file attached.
COULD NOT ATTACH LARGE ZIP FILE.
I have used "split" to split it into 250k chunks.
Just
cat xaa xab xac xad xae xaf > ZODB_ZIP.zip
unzip ZODB_ZIP.zip
The image was built on WinXP with MSVC 7.0.
Extract the zip. Then cd to the ZODB dir extracted.
c:/python22/python.exe test.py
The python.exe is from http://www.python.org/
Version: 2.2.2b1

ZEO/StorageServer.py isn't a script; it's just a module. If
you run the module as a script it won't start the server.
The failure you see might be because the path isn't set
properly.
If you try to import ZODB, that works, right? And import
ZODB.cPersistence also works?
For the crash, can you get a C stack trace from the debugger?

Following is the log when I try using ZEO/start.py
BTW StandAloneZODB worked fine on Solaris. Will try ZODB
3.1b2 on solaris later today.
Sorry for the flood of these bug updates. But I thought
separating these out would be more sensible.

OK. This, I tried on my Win2K (Pro) machine. Same
compiler. Downloaded Python 2.2.2b1.
After the following errors, the program crashed.

I have Win2K SP2 on this machine. Let me now try
StorageServer.

to that machine right now)

Um, StandaloneZODB 1.0 is a bit old. We've released ZODB 3.1
beta 2 recently, which should be its successor. Can you try
that?
