speed.pypy.org and old versions
by Matti Picus Nov. 11, 2016

Nov. 11, 2016

The landing page for speed.pypy.org, and the pull-downs on the other pages, are clogged with old results from previous versions. It seems the comparison page http://speed.pypy.org/comparison cannot even pull up the database info, and times out, making it useless. A quick fix could be to remove tags for much of the historical data, say for things more than 3 years old, keeping a smattering of significant versions? What you all think? Matti

PGO Optimized Binary
by Singh, Yashwardhan Nov. 10, 2016

Nov. 10, 2016

Hi All, We applied compiler assisted optimization technique called PGO or Profile Guided Optimization while building PyPy, and found performance got improved by up to 22.4% on the Grand Unified Python Benchmark (GUPB) from “hg clone https://hg.python.org/benchmarks”. The below result table shows majority of 51 micros got performance boost with 8 got performance regression. Benchmark Baseline PGO Perf Delta % hg_startup 0.0160 0.0124 22.4 2to3 6.1157 5.1978 15.… [View More]0 html5lib 4.9263 4.1961 14.8 formatted_logging 0.0463 0.0399 13.9 regex_v8 0.1394 0.1206 13.5 simple_logging 0.0328 0.0289 11.9 html5lib_warmup 2.5411 2.2939 9.7 bzr_startup 0.0686 0.0621 9.6 unpack_sequence 0.0001 0.0001 8.6 normal_startup 0.8694 0.7983 8.2 regex_compile 0.0707 0.0657 7.0 json_load 0.2924 0.2734 6.5 fastpickle 1.7315 1.6290 5.9 tornado_http 0.0707 0.0665 5.8 pickle_list 1.8614 1.7897 3.9 slowunpickle 0.0260 0.0250 3.8 slowpickle 0.0336 0.0323 3.7 telco 0.0194 0.0187 3.7 pathlib 0.0171 0.0165 3.2 go 0.1069 0.1036 3.1 slowspitfire 0.2624 0.2547 2.9 etree_generate 0.1037 0.1008 2.8 silent_logging 0.0000 0.0000 2.8 pickle_dict 3.2698 3.1796 2.8 spambayes 0.0581 0.0566 2.6 startup_nosite 0.5691 0.5549 2.5 chameleon_v2 2.7629 2.7009 2.2 etree_parse 0.5610 0.5505 1.9 etree_process 0.0725 0.0712 1.9 regex_effbot 0.0377 0.0371 1.7 fastunpickle 0.8521 0.8382 1.6 float 0.0171 0.0169 0.9 pidigits 0.3833 0.3801 0.8 call_method_unknown 0.0123 0.0122 0.6 hexiom2 15.8354 15.7533 0.5 etree_iterparse 0.2102 0.2094 0.4 chaos 0.0089 0.0088 0.2 spectral_norm 0.0099 0.0099 0.2 call_simple 0.0102 0.0102 0.1 mako_v2 0.0204 0.0204 0.1 fannkuch 0.2262 0.2260 0.1 unpickle_list 0.6448 0.6449 0.0 call_method_slots 0.0106 0.0106 0.0 call_method 0.0106 0.0106 -0.1 raytrace 0.0210 0.0210 -0.2 richards 0.0042 0.0043 -1.6 json_dump_v2 0.9288 0.9501 -2.3 django_v3 0.0551 0.0570 -3.4 meteor_contest 0.0984 0.1021 -3.8 nbody 0.0446 0.0463 -3.8 nqueens 0.0498 0.0525 -5.4 Average 3.6 We’d like to get some input on how to contribute our optimization recipe to the PyPy dev tree, perhaps by creating an item to the PyPy issue tracker?

pypy3.3: building extensions: environment variables CC etc - not honored
by Danny Milosavljevic Nov. 4, 2016

Nov. 4, 2016

Hi, I'm trying to package pypy3.3 for the Guix distribution. In the course of that I found that pypy3.3-v5.2.0-alpha1-src/lib-python/3/distutils/sysconfig_pypy.py doesn't honor the compiler environment variables ("CC" etc) like sysconfig_cpython.py does. Is that on purpose? If not, find attached a patch which makes it honor the variables (I have tested it and it works). Cheers, Danny

starting a release cycle
by Matti Picus Nov. 3, 2016

Nov. 3, 2016

I am thinking of pushing out what I guess should be PyPy2.7-5.6.0, we released PyPy2.7-v5.4.0 on Aug 31 and PyPy3.3-v5.5.0 on Oct 12. Are there outstanding branches that just have to be in this release or issues that we consider blockers? Would someone else like to pair with me for the release so they could do the next one? FWIW, I tick off the boxes on http://pypy.readthedocs.io/en/latest/how-to-release.html, not too hard really. I started a release notice http://pypy.readthedocs.io/… [View More]

Colo in Germany for the Windows build slave?
by Yury V. Zaytsev Nov. 2, 2016

Nov. 2, 2016

Hi there, I've been running the Windows build slave for the last ~1.5 years, but all good things come to an end, and I've been informed that I must shutdown the machine by the end of the year (that was the bad news). The "good" news is that I've been promised that I can have the hardware, so, in theory, if I can find colo to host it (Germany, preferably Cologne area), I can replace the hard drives, reshuffle the RAM, reinstall the system and plug it back in. If memory serves me well, it'… [View More]

Nov. 2, 2016

Hi, I'm currenlty working on the ssl stdlib replacement we agreed to implement during for py3.5. I'm unsure what the current rule for new project is. Github? Bitbucket? VMProf was initiated on Github, what did we learn from that experiment? Is the bar lower for new contributions? Cheers, Richard
