07:17 <krono> i got a problem: my rpython vm crashes with `pypy_g_IncrementalMiniMarkGC_unpin: unpin: object is already not pinned`

07:17 <krono> and I do not know where to start looking…

07:18 <bbot2> Success: http://buildbot.pypy.org/builders/jit-benchmark-linux-x86-64/builds/2660

07:25 <the_drow> krono, Start with setting the PYPY_GC_DEBUG environment variable to 1

07:25 <the_drow> See what happens

07:28 themsay has quit [Ping timeout: 246 seconds]

07:43 lritter has quit [Ping timeout: 245 seconds]

07:54 <krono> the_drow: same, no difference

07:54 <krono> no further output (its a lldebug0 build)

08:01 themsay has joined #pypy

08:08 <the_drow> Then you'll have to wait for arigo or cfbolz to respond

08:09 <cfbolz> krono: are you using pinning yourself?

08:11 <krono> cfbolz: no. its rsqueakvm and i just shoved shapes into it

08:11 <cfbolz> krono: OK. Does it happen without jit?

08:12 <krono> testing

08:15 <krono> yes

08:18 <krono> PYPY_GC_MAX_PINNED=0 helps, tho

08:27 adamholmberg has joined #pypy

08:28 <krono> cfbolz: is it "save" to run w/ max_pinned set to 0? or should I hunt that problem?

08:29 <cfbolz> krono: sure it's safe if somewhat slower, but it still man's there is a latent bug somewhere

08:31 <krono> cfbolz: Ok, thought so. anything i can do to help here?

08:32 adamholmberg has quit [Ping timeout: 245 seconds]

08:32 <cfbolz> Note that it's not unlikely that the bug is somewhere in rsqueak

08:32 <krono> maybe, yes.

08:32 <cfbolz> phlebas: do you have any memory of pinning being used in there?

08:32 <krono> grepping for pin yields nothing

08:33 <krono> I also manage to segfault the VM anyway when acting with my values, so there's that

08:33 <phlebas> we used to force pinned objects for the C API. krono, is that still included? I thought we removed that entire module

08:34 <krono> the c-api is gone, afaik

08:34 <cfbolz> krono: there may be a few APIs that pin but are not called that

08:34 <cfbolz> What you should do is use gdb to find out who calls the unpin

08:36 <krono> ah

08:36 <krono> rsdl…

21:24 <sfan5> I just stumbled upon something that's broken with pypy3 for seemingly no reason

21:24 <sfan5> >>>> __import__("ipaddress").ip_network('0.0.0.0/0').subnet_of

21:24 <sfan5> raises an AttributeError, but works perfectly fine in cpython

23:07 <tos9> sfan5: that's new in py37, and pypy has no 3.7 release.

23:07 <tos9> pypy3 assuming you're on the latest release is 3.6.
