Thibaut, I hadn't a chance to debug it with Windows but I wasn't happy with the locks we added and I have a few changes I want to make in trunk in this branch: https://code.launchpad.net/~openerp-dev/openobject-server/trunk- registry-lock-vmt/+merge/83602
I don't see how it could solve your problem but maybe it does.. can you give it a try? -- You received this bug notification because you are a member of C2C OERPScenario, which is subscribed to OpenERP Project Group. https://bugs.launchpad.net/bugs/885682 Title: [Trunk] Re-Entrant lock deadlock in upgrade_module Status in OpenERP Server: New Bug description: Hi. I'm using OpenERP Trunk (updated at the begining of the week) and I encounter a deadlock problem with threads. The bug is not easy to reproduce, because it's kind of random. The better I found to trigger it is to install/uninstall the same module different times. I looked into the code with pdb, and found that the block line is this one [1]: openerp/module/registry.py: with cls.registries_lock: I enabled the debug on the lock (passing verbose=True to the RLock constructor). Here is a "normal" output : netrpc-client-127.0.0.1:51862: <_RLock owner='netrpc-client-127.0.0.1:51862' count=1>.acquire(1): initial success netrpc-client-127.0.0.1:51862: <_RLock owner='netrpc-client-127.0.0.1:51862' count=2>.acquire(1): recursive success netrpc-client-127.0.0.1:51862: <_RLock owner='netrpc-client-127.0.0.1:51862' count=1>.release(): non-final release netrpc-client-127.0.0.1:51862: <_RLock owner=None count=0>.release(): final release But when there is the deadlock, I only get this output, before the server stop to respond : netrpc-client-127.0.0.1:51872: <_RLock owner='netrpc-client-127.0.0.1:51872' count=1>.acquire(1): initial success netrpc-client-127.0.0.1:51872: <_RLock owner='netrpc-client-127.0.0.1:51872' count=2>.acquire(1): recursive success I don't understand why it doesn't work because we can see that is has been release correctly just before (here, the output is from the same instance). Notes : - I couldn't trigger the bug on Linux, everything seems ok. But running the server on windows make this happen almost everytime. I don't really understand why, but I'm not an expert. - I was using the GTK Client - Using Python 2.6, with all libs installed manually using pip and .exe distributions. Thanks for working on this !
