03:34 <mattip> it seems cpython does not enforce using PySequece_Fast() before calling another PySequenceFast* function,

03:35 <mattip> so we crash on non-converted lists and tuples

09:41 <mattip_> numpy is now testing its interop with ctypes, but our memoryview(Structure) support is not good

09:41 <mattip_> so code like this fails https://gist.github.com/mattip/c9db1dbb57e1e22c1294c4b7f7f1b01b

09:42 <mattip_> we simply punt on the format string and return 'B'

09:43 <cfbolz> mattip_: yes, our ctypes is still fairly buggy :-(

09:44 <mattip_> is there a way to create a memorview object from pure python? I don't think so

09:46 <mattip_> maybe from _cffi_backend somehow

09:46 <mattip_> cfbolz: can you rubber duck a bit?

09:47 <cfbolz> I can try, but I know literally knowing about memoryview :-(

09:47 <mattip_> I am trying to trackdown where something is not right with unicode-utf8-py3

09:47 <cfbolz> mattip_: ^^

09:48 <mattip_> it translates and runs, but when I key in a unicode value in the repl it crashes

09:48 <mattip_> it seems like the unicode is being encoded as utf8 and the last bytes is being copied twice

09:48 <mattip_> but I don't understand where the keypress is being encoded. Is it pyrepl? is is somewhere else?

09:50 <mattip_> of course with pyinteractive everything works fine

09:55 <cfbolz> mattip_: how does it crash?

09:56 <cfbolz> I've seen some things like that in pdb on pypy as well

09:56 <cfbolz> on default though

09:57 <mattip_> it crashes when trying to decode the encoded utf8, since it has a repeated bytes sometimes that byte is invalid unicode

09:59 <mattip_> so the sequence seems to be unicode keypress -> encoded utf8 -> space.newtext(utf8) -> pyrepl.UnixConsole.refresh(utf8.decode)

09:59 <mattip_> the last step raises a fatal exception

10:02 <cfbolz> mattip_: is this a py3 only problem?

10:03 <mattip_> it seems like a unicode-utf8 only problem, but the unicode-utf8 branch does not translate now, after the rsre refactoring

10:03 <mattip_> where the unicode-utf8-py3 one does

10:03 <cfbolz> ah, right :-(

10:04 <cfbolz> mattip_: and let me guess, pyrepl is not tested?

10:04 <mattip_> something about context.next is not being annotated properly

10:04 <mattip_> on unicode-utf8

10:04 <cfbolz> otherwise you could run the pyrepl tests and try to narrow it down

10:04 <mattip_> tests do not seem to show the issue

10:04 <cfbolz> :-(

10:05 <mattip_> http://buildbot.pypy.org/summary?branch=unicode-utf8-py3

10:05 <mattip_> actually look pretty good

10:07 <mattip_> pypy.module._cffi_backend.test.test_re_python is broken on py3.5 too, so really there are less than 20 failing tests, other than pypyjit

10:07 <mattip_> maybe I'll just keep trying to fix those, and one will magiclly fix the repl problem

22:26 <mdash> if I wanted to build my rpython project as a shared library so it can be used in an embedded fashion like pypy, where would I start reading?

22:34 <mattip> mdash: look at the `shared` option http://doc.pypy.org/en/latest/config/translation.shared.html

22:35 <mattip> that is the "how", the "what" is more difficult to design

22:40 <mattip> mdash: for a "what not" see this issue https://bitbucket.org/pypy/pypy/issues/2617

22:40 <mdash> mattip: i've got some ideas for experimenting. :)

22:40 <mattip> about how PyPy should be exposing less

22:54 <mdash> mattip: thanks, this helps
