#pypy on 2018-07-04 — irc logs at freenode.irclog.whitequark.org

2018-02-26 15:52 cfbolz changed the topic of #pypy to: PyPy, the flexible snake (IRC logs: https://botbot.me/freenode/pypy/ ) | use cffi for calling C | the secret reason for us trying to get PyPy users: to test the JIT well enough that we're somewhat confident about it

04:55 <maxxam> cfbolz, LarstiQ, njs — segfault is still happening despite removing ujson

05:30 <cfbolz> maxxam: I fear you need to use a debugger

05:37 <bbot2> Failure: http://buildbot.pypy.org/builders/pypy-c-jit-macosx-x86-64/builds/3858 [py3.5]

05:39 <maxxam> cfbolz: yeah, it looks like you’re right. it will be a few days before I can make that happen, though.

05:41 <maxxam> Question. Is there a reliable way to tell from within a program whether it is running inside PyPy or CPython? e.g do `myvar = "foo" if __pypy__ else "bar"`

05:43 <maxxam> Never mind, found it: https://www.quora.com/How-do-I-know-if-a-Python-interpreter-is-a-CPython-implementation … `import platform; print platform.python_implementation()`

05:44 tbodt has quit [Quit: My Mac has gone to sleep. ZZZzzz…]

05:55 <cfbolz> maxxam: or try to import __pypy__

05:58 <maxxam> thanks :)

11:43 <Alex_Gaynor> timeshifter! the only thing cooler than the blackhole interpreter

11:44 <cfbolz> Alex_Gaynor: except it didn't actually produce fast code :-(

11:44 <Alex_Gaynor> it has a very cool name though

11:44 <cfbolz> I'm impressed that our executable was so tiny then, below 10mb!

11:45 <cfbolz> Alex_Gaynor: yep, terminology driven programming

11:45 <Alex_Gaynor> how many interpreters were in the binary :-)

11:45 antocuni has joined #pypy

11:46 <cfbolz> not enough, apparently

11:46 <cfbolz> Alex_Gaynor: now I'm trying to build the first tracing JIT, pypy 1.2

11:50 <antocuni> cfbolz: why?

11:50 <cfbolz> why what?

11:50 <antocuni> why are you trying to build old pypys?

11:51 <cfbolz> giving a "first 15 years of pypy" talk

11:51 <antocuni> ah, nice. At EP?

11:51 <cfbolz> no

11:51 <cfbolz> ICOOOLPS

11:52 <antocuni> ok

11:52 <antocuni> fwiw, who is coming to EP? I am coming, although my talk was not accepted

16:32 <mattip> I will be presenting a tutorial "CFFI, Ctypes, Cython: the Good, the Bad and the Ugly" at EuroSciPy

16:32 <mattip> and maybe add cppyy in as well

16:33 <mattip> regrettable Hehehe

16:36 <mattip> cfbolz: nice, sorry I will miss it

16:37 <cfbolz> arigato: sometimes I am indeed regretting

16:37 <cfbolz> I managed to compile pypy 1.2, the first version with a tracing jit

16:37 <cfbolz> It translated on the first try!

16:37 <cfbolz> Then it immediately crashes on anything I run that's not an empty loop 😂
