__signature__ for PySide ready
by Christian Tismer Aug. 19, 2017

Aug. 19, 2017

Hi friends, in the last months, I have developed signature support for PySide. The module creates the same signatures as are known for plain Python functions. As a non-trivial addition, the module also handles multiple signatures as a list. I consider this extension to PySide as quite essential and actually more important as for Python itself, because type info is rather crucial for PySide. Initially, I wrote this as a pure Python 3 extension. Then I was "asked" to port this to Python 2 too, which was quite hairy to do. I'm not sure if I should have done that. Before I publish this module, I want to ask: -------------------------------------------- Is it a bad idea to support signatures in Python 2 as well? Do I introduce a feature that should not exist in Python 2? Or is it fine to do so? Please let me know your opinion, I am happy with any result.

socketserver ForkingMixin waiting for child processes
by Victor Stinner Aug. 18, 2017

Aug. 18, 2017

Hi, I'm working on reducing the failure rate of Python CIs (Travis CI, AppVeyor, buildbots). For that, I'm trying to reduce test side effects using "environment altered" warnings. This week, I worked on support.reap_children() which detects leaked child processes (usually created with os.fork()). I found a bug in the socketserver module: it waits for child processes completion, but only in non-blocking mode. If a child process takes too long, the server will never reads its exit status and so the server leaks "zombie processes". Leaking processes can increase the memory usage, spawning new processes can fail, etc. => http://bugs.python.org/issue31151 I changed the code to call waitpid() in blocking mode on each child process on server_close(), to ensure that all children completed when on server close: https://github.com/python/cpython/commit/aa8ec34ad52bb3b274ce91169e1bc4a598… After pushing my change, I'm not sure anymore if it's a good idea. There is a risk that server_close() blocks if a child is stuck on a socket recv() or send() for some reasons. Should we relax the code by waiting a few seconds (problem: hardcoded timeouts are always a bad idea), or *terminate* processes (SIGKILL on UNIX) if they don't complete fast enough? I don't know which applications use socketserver. How I can test if it breaks code in the wild? At least, I didn't notice any regression on Python CIs. Well, maybe the change is ok for the master branch. But I would like your opinion because now I would like to backport the fix to 2.7 and 3.6 branches. It might break some applications. If we *cannot* backport such change to 2.7 and 3.6 because it changes the behaviour, I will fix the bug in test_socketserver.py instead. What do you think? Victor

Could someone review GH-2974 which add missing PyObject_GC_UnTrack()?
by INADA Naoki Aug. 18, 2017

Aug. 18, 2017

Hi. I created PR which fixes potential crash. Serhiy Storchaka approved it already, but he wants one other review from core dev. And I updated document after his review too. So I want more one reviewer for the PR. Someone help me? https://github.com/python/cpython/pull/2974 https://bugs.python.org/issue31095 ## Background For GC types, tp_dealloc should call PyObject_GC_UnTrack() before calling any APIs which can run arbitrary code, including Py_DECREF. Without calling it, GC may happen during tp_dealloc and GC will find object which refcnt == 0. I checked all GC types and find some unsafe tp_dealloc. Even "extending and embedding" document missed untracking. Regards, INADA Naoki <songofacandy(a)gmail.com>

Help requested with Python 2.7 performance regression
by Barry Warsaw Aug. 16, 2017

Aug. 16, 2017

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

Pull requests now have labels specifying what stage they are at
by Brett Cannon Aug. 11, 2017

Aug. 11, 2017

I just pushed a change to Bedevere to help track what stage a pull request is in. The stages are: - awaiting review - awaiting core review - awaiting changes - awaiting change review - awaiting merge The "review" stage is for when a pull request has no reviews either approving or requesting changes (this only applies to PRs not by a core dev; all PRs created by a core dev are flagged as awaiting merge immediately). The "core review" stage is when a review has been done by one or more non-core folk, but no core devs. The idea with the distinction is to encourage people to help in doing initial reviewing of PRs who happen to not be core devs since triaging issues and reviewing pull requests is the biggest chunk of work in maintaining CPython. The "changes" stage occurs when a core dev requests changes to a PR (a non-core dev review will not trigger this). A comment will be left to this effect with instructions for the PR creator to leave a comment saying "I didn't expect the Spanish Inquisition" to signal when they believe they are done addressing the reviewer's comments (there is also appropriate comments to explain the quote along with an easter egg(s) :) . The "change review" label means that the PR creator left the Spanish Inquisition quote and so now the core dev(s) who requested changes should re-review the PR. There will be a comment mentioning the core devs to this effect so that they will get a proper GitHub notification and they can check the label to see if the PR creator believes they are ready for another round of review (compared to now where you have to hunt around in the PR to see if it's ready for another review). The "merge" label means the PR has received an approving review from a core dev and so it should be ready to go. Now when any state change happens to trigger these labels, any preexisting "awaiting" label will be cleared and the new one set. But removing or setting a label manually won't trigger an action, so in this instance you can override Bedevere manually until some later event occurs which triggers an automatic update. One thing I do want to call out is that it's now more important that core devs leave appropriate "approved" and "request changes" reviews through the GitHub UI instead of just leaving a comment when they approve or want changes to a PR, respectively. Not only is this necessary to automate this part of the stage labeling, but it also visibly exposes in the GitHub UI the review state of a PR. I'm not backfilling the open PRs as it's more work and I don't want to do said work. ;) But as PRs are opened, reviewed, etc., things should slowly trickle their way through the various PRs. I should mention this is the second-to-last "intrusive" workflow change I have planned to introduce some new aspect to the workflow (the last one being a status check for a news entry after every branch has been blurbified). After these two changes land, everything else I have planned is just touching things up (e.g. the CLA check becoming a status check instead of a label, touching up CONTRIBUTING.md, etc.). I think some other people have plans to improve things as well, but at least my TODO list of "radical" changes to our workflow is almost done!

bugs.python.org - outage 08/09/17 until 8:00pm PST
by Mark Mangoba Aug. 10, 2017

Aug. 10, 2017

Dear Colleagues, I was just informed from our hosting provider for bugs.python.org <http://bugs.python.org/>, Hetzner Online - that the server is currently being migrated to a new data center. Unfortunately I was not informed ahead of time and working with the provider to better communicate and schedule future maintenance periods accordingly. Apologies for any inconvenience this has caused. I will be posting status updates at https://status.python.org/ <https://status.python.org/>. As many of you know, we are working to migrate this off the current hosting provider in the next 3 months. Best regards, Mark Mark Mangoba | PSF IT Manager | Python Software Foundation | mmangoba(a)python.org | python.org | Infrastructure Staff: infrastructure-staff(a)python.org | GPG: 2DE4 D92B 739C 649B EBB8 CCF6 DC05 E024 5F4C A0D1
