RE: [Zope] Restart bug *and* shutdown bug
-----Original Message----- From: Sam Gendler [mailto:sgendler@impossible.com]
I suspect that this is a problem caused by a race condition that only occurs when you have high speed access. I have a very fast network here, and I can use any combination of machines and OSes and still see the problem.
Possibly. I can now reproduce the bug but not very consistently. This is what I see with a Zope running on my machine, aldous. If I use a browser on aldous: then clicking shut-down usualy shuts it down but sometimes requires me hitting shutdown twice. clicking restart cause Zope NOT to restart and *sometimes* it crashes (no core file though...but the process exits), and I get one of two error messages, either: TypeError Traceback (innermost last): <snip> File /home/michel/src/test/Zope-2.1.2-linux2-x86/lib/python/ZPublisher/BaseRe quest.py, line 285, in traverse TypeError: unbound Python method must be called with Acquirer 1st argument ****OR**** ValueError Traceback (innermost last): <snip> File /home/michel/src/test/Zope-2.1.2-linux2-x86/lib/python/ZODB/FileStorage. py, line 593, in modifiedInVersion (Object: /home/michel/src/test/Zope-2.1.2-linux2-x86/var/Data.fs) ValueError: I/O operation on closed file in the case of getting *either* error message, I get this in the Zope log: ------ 2000-01-12T21:27:28 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\000\005' If I run a browser on another machine called korak: clicking shutdown causes the Zope process to exit clicking restart causes the Zope process to exit also Can someone verify that this is also the case for them? Or do other people have different symptoms? -Michel
I will do a comprehensive test of multiple configurations in just a bit. I don't have time immediately, but I will get it done today. --sam Michel Pelletier wrote:

clicking restart cause Zope NOT to restart and *sometimes* it crashes (no core file though...but the process exits), and I get one of two error messages, either:
TypeError

in the case of getting *either* error message, I get this in the Zope log:
------ 2000-01-12T21:27:28 ERROR(200) ZODB Couldn't load state for '\000\000\000\000\000\000\000\005'
If I run a browser on another machine called korak:
clicking shutdown causes the Zope process to exit
clicking restart causes the Zope process to exit also
Can someone verify that this is also the case for them? Or do other people have different symptoms?
