08:13 <arigato> so, another reason to give .so different names for cpyext and for cffi:

08:13 <arigato> https://bitbucket.org/pypy/pypy/issues/2798/initializing-a-global-pyobject-crashes

08:19 <antocuni> arigato: we should just do it probably. The time spent for debugging this issue is already more than what it takes to give different names :)

08:19 marr has joined #pypy

08:28 <arigato> well, we need to mess with distutils and I don't know how much with setuptools, to give them different names

08:28 <arigato> it's very likely to add its own set of bugs

08:31 jaffachief has joined #pypy

08:32 <antocuni> I naively assumed that it was enough to change the SOABI, but indeed there might be code which assumes that the soabi is unique for a given interpreter

08:33 energizer has quit [Ping timeout: 264 seconds]

08:35 <arigato> ah, maybe it is enough

08:35 <arigato> and if all else fails we can probably just rename the .so manually?

08:36 <antocuni> "manually" when?

08:36 <antocuni> the final file is produced by distutils, so I'm not sure when is the correct time/hook to rename it

08:36 <arigato> when building the so for cffi

08:37 <antocuni> ah, right

08:37 <arigato> well, maybe

10:10 <antocuni> mattip: I finally managed to document and merge the branch :)

10:10 <antocuni> not sure if it's still in time to get it into the release

10:12 <mattip> antocuni: there is time. let's give it a day or two to settle

10:13 <antocuni> cool, thanks

10:13 <antocuni> I'll try to merge it to py3.5 as well

10:26 <antocuni> cool, I can merge gc-hooks to py3.5 without conflicts. I'm trying a translation, if it works I'll just merge&commit

10:57 <arigato> mattip: see problem in https://bitbucket.org/pypy/pypy/issues/2798/initializing-a-global-pyobject-crashes

11:00 <mattip> arigato: as I read it, the issue is initializing cpyext before calling dlopen, and we do not want to do that universally

11:00 <mattip> since it will slow down programs that use only cffi, not cpyext

11:01 <mattip> but don't we know before dlopen that we are importing a python module, not a cffi shared object?

11:01 <arigato> no, how?

11:02 <arigato> at the moment the difference is about which symbol that library exports

12:21 <arigato> yes, the problem here is that dlopen potentially executes some code which expects cpyext to be initialized already

13:32 <antocuni> cfbolz: good idea about documenting which thread runs the hooks

13:32 <antocuni> the only thing is... I have no idea :)

13:33 <bbot2> Failure: http://buildbot.pypy.org/builders/pypy-c-jit-linux-s390x/builds/837 [default]

13:36 <antocuni> gc hooks use the AsyncAction mechanism for running the hooks; I don't know whether they are executed in a random thread or e.g. in the main one
