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.

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.

Maybe I am doing something wrong. This did not happen for

OK. This, I tried on my Win2K (Pro) machine. Same
compiler. Downloaded Python 2.2.2b1.
After the following errors, the program crashed.
(Instruction at 0x... referenced memory at 0x000000..)

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

I will send an exact error log later today. (Don't have access
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?
