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

15:46 <arigo> Wulf: I cannot reproduce your problem, at least on Linux using the official distribution: all of cpython 2.7, cpython 3.5, pypy2 and pypy3 take almost the same time

15:46 <arigo> it is however possible that you're using a miscompiled version of pypy, because we have a pure-python fallback for sha256

15:47 <Wulf> arigo: I didn't compile it myself

15:47 <arigo> yes, I don't want to say "bad person" here

15:47 <arigo> you're using the one provided by Debian, I guess?

15:48 <Wulf> arigo: https://bitbucket.org/pypy/pypy/downloads/pypy3-v6.0.0-linux64.tar.bz2 on debian/unstable

15:48 <arigo> ah

15:50 <Wulf> arigo: what implementation is used, openssl?

15:51 <Wulf> or *should* be used

15:51 <arigo> yes

15:51 <Wulf> static or dynamic linked?

15:52 <Wulf> when I look at /proc/xxx/maps I can't see any ssl or crypto

15:53 <arigo> I get the same result with this

15:53 <arigo> it is using cffi

15:53 <arigo> at least for ssl, let me check

15:54 <arigo> does this line work for you: "import _hashlib"?

15:54 <Wulf> ImportError: libssl.so.1.0.0: cannot open shared object file: No such file or directory

15:55 <arigo> ok

15:55 <Wulf> ok, that explains it

15:55 <Wulf> build isn't suitable for my system

15:55 <arigo> ah, it's lib_pypy/_pypy_openssl.pypy3-60-x86_64-linux-gnu.so

15:55 <arigo> which is not loadable on your system indeed

15:56 <arigo> you should be able to run

15:56 <arigo> cd ../lib_pypy

15:56 <arigo> ../bin/pypy3 _ssl_build.py

16:00 <Wulf> arigo: thanks, much better! Now it also appears in proc/maps

16:01 <Wulf> How about spitting out a warning when openssl (or other fast implementation) can't be used?

16:11 <kenaan> arigo default f59578325003 /lib-python/2.7/hashlib.py: Give a warning when we can't import _hashlib

16:11 <kenaan> arigo py3.5 f21562687ea4 /lib-python/3/hashlib.py: Give a warning when we can't import _hashlib

16:19 <kenaan> arigo default 6868da604e68 /rpython/rlib/buffer.py: Add a get_raw_address() in the base class---better than segfaulting due to calls to a missing method!

16:30 arigo is now known as arigato

16:30 <arigato> hope it works.

16:31 <kenaan> arigo py3.5 130fbb74dab5 /: hg merge default

16:31 <kenaan> arigo py3.5 8e5a7f8a9bf2 /pypy/module/_io/interp_bytesio.py: Remove this get_raw_address() now that we have one in the base class

16:31 <arigato> Wulf: I tested it manually but it's hard to write systematic tests for that

16:38 <Wulf> could build on one platform and test on another

16:38 <Wulf> But that's kind of pointless, it's not supposed to work anyway
