Have a big machine and spare time? Here's a possible Python bug.
by Tim Peters July 19, 2019

July 19, 2019

There's a Stackoverflow report[1] I suspect is worth looking into, but it requires far more RAM (over 80GB) than I have). The OP whittled it down to a reasonably brief & straightforward pure Python 3 program. It builds a ternary search tree, with perhaps a billion nodes. The problem is that it "takes forever" for Python to reclaim the tree storage when it goes out of scope (the author waited at least hours). Alas, the OP said it takes about 45 minutes to build the tree, and the problem goes away if the tree is materially smaller. So it takes a long time just to try once. With a tree about 10x smaller, for me it takes about 45 seconds for Python to reclaim the tree storage. The tree is deep enough that the "trashcan" may be implicated, and the node objects are small enough that obmalloc carves them out of a (relatively) great many arenas. Those are two ways in which Python _may_ be to blame. The sheer number of objects involved may be provoking edge cases we normally never see. But, for a start, it would be good to know if anyone else can actually reproduce the problem. [1] https://stackoverflow.com/questions/56228799/python-hangs-indefinitely-tryi…

bpo-37468: make install no longer install wininst-*.exe files
by Victor Stinner July 16, 2019

July 16, 2019

Hi, I modified Makefile.pre.in to avoid installing wininst-*.exe files, since these files are only useful on Windows: the distutils bdist_wininst command only works on Windows. https://bugs.python.org/issue37468 I made the assumption that "make install" is only used on Unix, not on Windows. I never tried to build Python in Cygwin or MinGW on Windows. If someone knows these platforms, and consider that wininst-*.exe should still be installed on these platforms, please propose a pull request for bpo-37468. By the way, bdist_wininst is now deprecated in Python 3.8: wheel packages are now preferred. https://bugs.python.org/issue37481 Victor -- Night gathers, and now my watch begins. It shall not end until my death.

bpo-34788 needs a review
by Sasha Pavlyuk July 15, 2019

July 15, 2019

Hello 2019-06-03 I have created PR https://github.com/python/cpython/pull/13772 , which adds IPv6 scoped addresses support to ipaddress module. It is very critical to everyone, who is dealing with IPv6 networking. For example, in salt project they use patched module. So, it would be very nice to have my changes merged and avoid such a workarounds. Here is link to the bug - https://bugs.python.org/issue34788. Please, pay attention to this issue.

Keyword arguments with non-string names
by Jeroen Demeyer July 10, 2019

July 10, 2019

When passing **kwargs to a callable, the expectation is that kwargs is a dict with string keys. The interpreter enforces that it's a dict, but it does NOT check the types of the keys. It's currently the job of the called function to check that. In some cases, this check is not applied: >>> from collections import OrderedDict >>> OrderedDict(**{1:2}) OrderedDict([(1, 2)]) So this leads to the question: should the interpreter check the keys of a **kwargs dict? I don't have an answer myself, I'm just asking the question because it comes up in https://github.com/python/cpython/pull/13930 and https://github.com/python/cpython/pull/14589 Jeroen.

Docs: audit event table empty
by Christian Heimes July 9, 2019

July 9, 2019

Hi, the table with auditing events does not render on docs.python.org, https://docs.python.org/3.9/library/audit_events.html. Steve and I are going to present the auditing feature tomorrow at EuroPython. It would be helpful to have the table available. It works on Steve's and my local machine without any issues. I suspect it's either an outdated sphinx version or caching issue. Could somebody from the docs team or shell access to the docs machine please look into the matter? Thanks! Christian

[Possibly off-topic] Python-Announce floods and delays
by Jonathan Goble July 9, 2019

July 9, 2019

(I don't know the best list to post this to, so if this is not it, please forgive me and point me in the right direction. Thanks.) So my inbox, and probably many of yours, was flooded this afternoon with a dozen-plus emails from the Python-Announce list. I understand that this list requires every email to be manually approved by a moderator. The problem is that this is done infrequently. Prior to today, the last round of approvals was June 26, almost two weeks ago. This is not an atypical delay; on the contrary, it seems that moderators only look at the queue once every one to two weeks. There are several problems with these delays: 1. They result in floods of emails, with a large number of emails in a short period of time. This makes inbox management difficult on the days that approvals are done. Before you argue that "it's fine if you have the right tools configured in the right way", consider that there are probably many people who are subscribed to Python-Announce who have no interest in and are not subscribed to any of the actual discussion lists where such tools are most beneficial. Complex tool configurations should not be a requirement for managing incoming emails from what is essentially (to those people) a notification-only mailing list. These people would be better served by frequent approvals several times a week, allowing them to get fewer emails at one time, but in a more timely manner. 2. Speaking of a more timely manner, the lengthy delays result in redundant and outdated emails going through after the point where they are no longer relevant. One such issue exemplified by today's set of approvals (and seen on previous occasions before) is an announcement of a new release of a PyPI package not being approved until after there has already been a subsequent release to that same package. In this case I am referring to the pytest 5.0.0 announcement sent to the list on June 28 (according to the headers), followed by the pytest 5.0.1 announcement sent to the list on July 5. Neither was approved and delivered to subscribers until today. 3. More importantly in terms of delays, on July 3 an announcement was sent to the list regarding the impending switch of EuroPython ticket rates to the late registration rate on July 6. This is an example of a time-sensitive announcement that needs to not be delayed. Instead, the email was not approved and delivered to subscribers until today, July 8, after the conference has already begun, and not in time for list subscribers to react and avoid the late registration rates. Is there a solution to this that would enable moderators to approve more frequently? I understand that they are probably volunteers and need to find spare time to wade through the queue, but if approvals are done more frequently (even daily), then it will consume much less time on each occasion. It would go from a task requiring an entire hour (as it apparently did today based on the delivery timestamps) to something that can be done on a coffee break.

[RELEASE] Python 3.8.0b2 is now available for testing
by Łukasz Langa July 8, 2019

July 8, 2019

After a few days of delay, but somewhat cutely timed with the US Independence Day, I present you Python 3.8.0b2: https://www.python.org/downloads/release/python-380b2/ <https://www.python.org/downloads/release/python-380b2/> This release is the second of four planned beta release previews. Beta release previews are intended to give the wider community the opportunity to test new features and bug fixes and to prepare their projects to support the new feature release. The next pre-release of Python 3.8 will be 3.8.0b3, currently scheduled for 2019-07-29. Call to action We strongly encourage maintainers of third-party Python projects to test with 3.8 during the beta phase and report issues found to the Python bug tracker <https://bugs.python.org/> as soon as possible. While the release is planned to be feature complete entering the beta phase, it is possible that features may be modified or, in rare cases, deleted up until the start of the release candidate phase (2019-09-30). Our goal is have no ABI changes after beta 3 and no code changes after 3.8.0rc1, the release candidate. To achieve that, it will be extremely important to get as much exposure for 3.8 as possible during the beta phase. Please keep in mind that this is a preview release and its use is not recommended for production environments. No more non-bugfixes allowed on the “3.8” branch The time has come, team. Please help make Python 3.8 as stable as possible and keep all features not currently landed for Python 3.9. Don’t fret, it’ll come faster than you think. - Ł
