2022-04-07 20:04 cfbolz changed the topic of #pypy to: #pypy PyPy, the flexible snake https://pypy.org | IRC logs: https://quodlibet.duckdns.org/irc/pypy/latest.log.html#irc-end and https://libera.irclog.whitequark.org/pypy | Matti: I made a bit of progress, the tests now only segfault towards the end

04:46 <nel> hello! can someone help me?

04:50 <nel> i have pypy 7.3.9 and it is having trouble storing japanese characters. when i enter a string with jp chars in the interpreter it gets converted to question marks.

06:26 <LarstiQ> nel: that sounds like an encoding issue?

06:27 <LarstiQ> what's sys.getdefaultencoding()? What is your terminal using? does it work with cpython?

06:28 <nel> sys.getdefaultencoding() == 'utf-8' and sys.getfilesystemencoding() == 'utf-8'

06:29 <nel> yes, it works in normal python

06:30 <nel> i'm using windows terminal

06:36 <nel> what's weird to me is that it's literally equal to '?'. ('あ' == '?') is True

06:38 <LarstiQ> ah, is the window terminal using utf8?

06:38 <LarstiQ> also, pypy2 or pypy3, byte or unicode strings?

06:38 <nel> also, b'\xe3\x81\x82'.decode('utf-8') returns different values in cpython and pypy

06:38 <nel> i have pypy3

06:38 <LarstiQ> something like https://stackoverflow.com/questions/24140497/unbaking-mojibake might also be insightful

06:41 <mattip> nel: pypy on windows has problems with its console,

06:42 <mattip> we have not been able to get the winconsoleio module working

06:43 <nel> i see, let me try on linux. if that works i'll just switch to cpython for this project and wait for the fix.

06:44 <mattip> it might be quite a wait, the work needs a champion

06:45 <nel> yeah works just fine on wsl

06:45 <nel> thanks for the response tho

06:46 <nel> i specifically want to use stackless module. are you aware if i can install it in cpython?

06:46 <mattip> nel: I am confused about b'\xe3\x81\x82'.decode('utf-8'), it seems to me to give the same result everywhere

06:47 <mattip> on windows, I see the unicode character, not '?'

06:48 <nel> matt: do you see 'あ'? i see 'πüé' on pypy3 on windows

06:49 <mattip> what does pypy -c "import sys; print(sys.version)" show?

06:50 <nel> 3.9.10 (b332b321bbaa72bffb0207da5b7fe4c38047d3b2, Mar 16 2022, 16:03:21)

06:50 <nel> [PyPy 7.3.9 with MSC v.1929 64 bit (AMD64)]

06:50 <mattip> so maybe because I have codepage 850?

06:51 <mattip> from the dos terminal, what does "chcp" show

06:51 <nel> Active code page: 437

06:53 <mattip> can you try "chcp 850" (for latin-1) or "chcp 65001" (for utf-8)?

06:54 <mattip> you can make this permanent by this

06:54 <mattip> https://stackoverflow.com/questions/57131654/using-utf-8-encoding-chcp-65001-in-command-prompt-windows-powershell-window

06:56 <mattip> (I would be surprised if stackless still works, I think the last release was ~8 years ago. These days asyncio is the new shiny)

06:58 <nel> chcp 65001 is displaying the character alright

06:59 <nel> input is still incorrect though, now ('あ' == ' ') is True lol

07:02 <mattip> with cp 850 it works, with cp 65001 I get a ValueError: source code string cannot contain null bytes

07:02 <nel> asyncio looks neat. does it have channels? i cant find anything builtin, only other pip libraries.

07:03 <mattip> there is low-level built in support, and wrapper libraries to provide the sugar needed to make it usable

07:04 <mattip> I am not an expert, but a search showed me https://pypi.org/project/asyncio-channel/

07:04 <mattip> but we diverge ...

07:04 <nel> yeah

07:07 <nel> thank you for your help :)

07:09 <mattip> nel: did you try "chcp 850"?

07:11 <nel> 'あ' == '?' and b'\xe3\x81\x82'.decode('utf-8') == 'Òüé'

07:30 <mattip> weird. I opened an issue https://foss.heptapod.net/pypy/pypy/-/issues/3777

07:45 <mgorny> mattip: found a small bug in hashlib: https://foss.heptapod.net/pypy/pypy/-/issues/3778 ;-)

07:48 greedom has joined #pypy

07:56 <nel> mattip: thanks. for clarity - with chcp 65001, 'あ' == ' ' (that's a space, not empty str)

07:57 <nel> nevermind

07:58 <nel> i'm hitting UP and RETURN and getting a different string each time

08:04 <nel> giving up on the dos terminal. using a modern terminal, i'm getting 'あ' == '?' consistently with chcp 850 and `ValueError: source code string cannot contain null bytes` with chcp 65001

08:04 <nel> also, i'm now getting b'\xe3\x81\x82'.decode('utf-8') == 'πüé' for both chcp 850 and 65001

22:24 <mattip> mjacob: we have constraints. What do you mean "move around a bit"?

22:24 <mattip> that is pretty much the only week that works

22:24 <mjacob> mattip: there's a mercurial conference on september 21-23

22:25 <mjacob> depending on where and when exactly the pypy sprint is, i might still visit both

22:26 <mattip> I think cfbolz was proposing Dusseldorf, Sept 19-23

22:27 <mattip> I cannot come if it is any later, and I think others have commitments before Sept 18

22:35 <mjacob> oh, that's unfortunate (given that the chance of a complete overlap seems low)
