congrats on 3.5! Alas, windows 7 users are having problems installing it

by Laura Creighton

webmaster has already heard from 4 people who cannot install it. I sent them to the bug tracker or to python-list but they seem not to have gone either place. Is there some guide I should be sending them to, 'how to debug installation problems'? Laura

Help requested with Python 2.7 performance regression

by Barry Warsaw

Hello all, Over in Ubuntu, we've gotten reports about some performance regressions in Python 2.7 when moving from Trusty (14.04 LTS) to Xenial (16.04 LTS). Trusty's version is based on 2.7.6 while Xenial's version is based on 2.7.12 with bits of .13 cherry picked. We've not been able to identify any change in Python itself (or the Debian/Ubuntu deltas) which could account for this, so the investigation has led to various gcc compiler options and version differences. In particular disabling LTO (link-time optimization) seems to have a positive impact, but doesn't completely regain the loss. Louis (Cc'd here) has done a ton of work to measure and analyze the problem, but we've more or less hit a roadblock, so we're taking the issue public to see if anybody on this mailing list has further ideas. A detailed analysis is available in this Google doc: https://docs.google.com/document/d/1zrV3OIRSo99fd2Ty4YdGk_scmTRDmVauBprKL8e… The document should be public for comments and editing. If you have any thoughts, or other lines of investigation you think are worthwhile pursuing, please add your comments to the document. Cheers, -Barry

Star the CPython GitHub project if you like Python!

by Victor Stinner

Hi, GitHub has a showcase page of hosted programming languages: https://github.com/showcases/programming-languages Python is only #11 with 8,539 stars, behind PHP and Ruby! Hey, you should "like" ("star"?) the CPython project if you like Python! https://github.com/python/cpython/ Click on "Star" at the top right. Thank you! Victor

New work-in-progress bisection tool for the Python test suite (in regrtest)

by Victor Stinner

Hi, Last weeks, I worked on a new tool to bisect failing tests because it's painful to bisect manually reference leaks (I remove as much code as possible until the code is small enough to be reviewable manually). See the bisect_test.py script attached to this issue: http://bugs.python.org/issue29512 With the help of Louie Lu, I added new --list-cases option to "python -m test", so you can now list all test cases and write it into a text file: ./python -m test --list-cases test_os > tests I also added a new --matchfile option, to filter tests using a text file which contains one pattern per line: ./python -m test --matchfile=tests test_os fnmatch is used to match test names, so "*" joker character can be used in test names. My bisection tool takes a text file with the --matchfile format (one pattern per line) and creates a random subset of tests with half of the tests. If tests still fail, use the subset. Otherwise, create a new random subset. Loop until the subset contains a single test (configurable threshold, -n command line option). The long term plan is to integrate the bisection feature directly into regrtest. Right now, my script is hardcoded to bisect reference leak bugs, but it should be easy to modify it to bisect other test issues like test creating files without removing it ("ENV_CHANGED" failure in regrtest). For example, a core file is dumped when running test_subprocess on FreeBSD buildbots: http://bugs.python.org/issue30448 But I'm unable to reproduce the issue on my FreeBSD. It would be nice to be able to automate the bisection on the buildbot directly. --list-cases and --matchfile options are now available in 2.7, 3.5, 3.6 and master (3.7) branches. TODO: doctest tests are only partially supported, see: http://bugs.python.org/issue30683 Victor

Buildbot report (almost July)

by Victor Stinner

Hi, Our buildbots are now even more stable than in my previous buildbot report. Many random failures have been fixed, even if there are still many rare random failures (most of them are related to multiprocessing). Search for issues created by "haypo" (me!) with the Component "Tests" to see all remaining issues. I'm trying to open an issue for *each* buildbot failure! So yeah, we have a long list of 44 open issues! Correct me if I'm wrong, but, for the first time, *all reference leaks* have been fixed on *all branches* (2.7, 3.5, 3.6 and master), on *Linux and Windows*! Before, we mostly focused on the master branch (called "default" in Mercurial) on Linux. I also started to fix a few "memory block" leaks, most (or all?) of them should also be fixed (on all branches, on Linux and Windows). A new policy has been decided (on python-committers): if a commit breaks too many buildbots and cannot fixed easily nor quickly, the commit will be reverted, just to keep our buildbots "green". It doesn't mean that the commit will be rejected forever. It's a practical solution to give more time to write a proper fix, take time to review it, and not have to be stressed to fix buildbots "ASAP". Moreover, keeping green buildbots all the time allows to catch regressions more quickly, which ease debug in many ways. You have be warned! Now I will not hesitate to revert your change if you break my little buildbots ;-) I mostly care of Linux, Windows, macOS and FreeBSD (10 and CURRENT). Breaking other platforms is less important, since other platforms already have issues, but not enough developers interested to fix them. Obviously, I'm interested in keeping more buildbots green, if someone shows up and help me to fix remaining issues! Victor

Re: [Python-Dev] Star the CPython GitHub project if you like Python!

by rymg19＠gmail.com

I had tried to get people to star it after the GitHub migration, but I don't think too many did... FWIW Python's doing pretty well on GitHub considering it's only been there a couple of months. Only other project that did so well was Swift, and that was partly because it was previously closed-source. -- Ryan (ライアン) Yoko Shimomura, ryo (supercell/EGOIST), Hiroyuki Sawano >> everyone elsehttp://refi64.com On Jun 30, 2017 at 9:01 AM, <Victor Stinner <victor.stinner(a)gmail.com>> wrote: Hi, GitHub has a showcase page of hosted programming languages: https://github.com/showcases/programming-languages Python is only #11 with 8,539 stars, behind PHP and Ruby!

I¹m happy to create a PR with a > cherry-picked commit, and/or test. Sure, this change can be backported to 3.6, maybe also to 3.5. But hum, I may suggest to first focus on the master branch and fix most HP-UX issues, before spending time on backport. I would prefer to see most tests of the important modules pass on HP-UX (ex: test_os). For a backport, you can directly comment http://bugs.python.org/issue30183 Victor

Bug in buildbot view (changes column)

by Antoine Pitrou

Hello, If you look at this page (waterfall view of 3.x unstable buildbots), you'll notice the "changes" column on the left lists the recent changesets on master: http://buildbot.python.org/all/waterfall?tag=3.x.unstable However, on the equivalent view for 3.x stable buildbots, the "changes" column on the left is empty: http://buildbot.python.org/all/waterfall?category=3.x.stable Is there a particular reason? Oh wait... The first URL lists "3.x.unstable" as a *tag* while the second URL lists "3.x.stable" as a *category*. If I change the second URL to use "tag" instead of "category", the "changes" column miraculously lists the recent changesets: http://buildbot.python.org/all/waterfall?tag=3.x.stable Finicky buildbot :-/ Regards Antoine.
