<rindolf> Hi all! This numpy program is very slow in pypy - https://paste.debian.net/1090481
<fijal> rindolf: this is kind of expected - operations on numpy arrays are slow
<rindolf> fijal: ah.
<fijal> we never managed to find money for the proposal to make them fast either
<fijal> it's at least in theory a fixable problem
<rindolf> fijal: thanks
<rindolf> fijal: here t2-t1 is larger on pypy3 than on cpython3 - https://paste.debian.net/1090483

<_aegis_> would it be easier to run translation on python3
<_aegis_> than hack up cpython2

<fijal> _aegis_: I'm not completely convinced this writing is the current thinking
<fijal> or the only way to do it
<_aegis_> I didn't realize there was no win64 target, but I will need it eventually
<fijal> but making it python3 seems like a doomed proposition
<_aegis_> so I might be incentivized to work on it
<fijal> so, we never actually found out ~50k USD that's needed to do it
<fijal> which makes one think that it's not really a thing anyone cares about
<_aegis_> I care about it :)
<fijal> do you care enough to either work on it or convince someone to pay us?
<_aegis_> I just said I might be incentivized to work on it

<_aegis_> I could maybe ship a 32-bit app initially but I'd really rather not
<fijal> it's quite a bit of annoying work
<_aegis_> you mostly talking about the "porting the rpython code" part?
<_aegis_> I'm shipping a mac app with pypy3 embedded, it was a relatively painless port to linux, was expecting more of the same for windows until I noticed there's no pypy target :)
<fijal> generally removing the assumption that sizeof(intptr_t) == sizeof(long)
<_aegis_> is there likely much actual windows api stuff, or does the 32-bit port probably have most of that covered already?
<_aegis_> right now I'm taking another stab at supporting zipimport for the whole stdlib, I think it will improve my app start times and generally make copying my app around faster

<oberstet> fijal: hey. re arm64 .. awesome!!
fling has joined #pypy
<oberstet> have you had a chance to check if aws graviton also works already?
<oberstet> it _should_ but it is a complete own armv8 impl - I think .. - and having an easily accessible cloud arm64 of course is neat (also for building docker images etc based on the new pypy then)

<fijal> oberstet: yes, this is what we're testing on
<rindolf> fijal: hi, any idea why https://github.com/shlomif/primesieve-python/tree/array-pypy3 (note the branch) gives me <<ValueError: array.array size changed, may indicate binary incompatibility. Expected 72 from C header, got 24 from PyObject>> in pypy3 and works fine in cpython3?
<fijal> rindolf: no clue
<rindolf> fijal: ah
<rindolf> fijal: thanks

<ronan> rindolf: it's a spurious warning from Cython, I thought we'd fixed it, but I've forgotten some of the details
<ronan> rindolf: which Cython version are you using?
<rindolf> ronan: latest
<ronan> hmm, then I guess we didn't fix the issue for array.array
<ronan> but it's (probably) harmless: Cython is reading a field that cpyext adds purely for compatibility's sake
<rindolf> ronan: cython 0.29.11
<rindolf> ronan: ok
<rindolf> ronan: after i #if 0 ed the checks in the .cpp pypy3 now segfaukts
forgottenone has joined #pypy
<ronan> rindolf: hmm, I'm not quite sure what's going on. I don't have time to look into it properly now, though. Can you open an issue please?
<oberstet> fijal: perfect, thanks for the update!
<rindolf> ronan: yes
<rindolf> note that bitb again forgot my login
<_aegis_> :o that was easier than I thought
<_aegis_> ~3 lines to fix zipimport stdlib
<_aegis_> I want to PR but I'm not sure which branch this kind of thing would go against - looks like master has different code in sys/modules/initpath than py3.6, which is where I want to use it
<cfbolz> _aegis_: py3.6
<_aegis_> I'm still shipping pypy3.5, is 3.6 feeling mostly stable by now?

<mattip_> fijal: around?
<mattip_> I am pretty sure I tried the ARM32 I built on the AWS chroot buildbot on my 32-bit machines at home and it worked fine
<mattip_> but the best would be to simply run it again to make sure
