The check would inform (especially for old files) or remind (for new files) so that judgment could be applied. Ah, right. Yeah, that may be reasonable. A warning option on reindent.py may be a place to start if someone wanted to implement it. Whether or not patchcheck used that option would likely depend on the initial results of running it manually :) Cheers, Nick. > > _______________________________________________ > Python-checkins mailing list > Python-checkins(a)python.org > http://mail.python.org/mailman/listinfo/python-checkins

That raises issues when modifying existing non-compliant files, because it removes the human judgement on whether a non-compliance is worth fixing or not.

PEP 446: Open issues/questions
by Victor Stinner 02 Aug '13

02 Aug '13

Hi, I have a few more questions on the PEP 446: (A) How should we support support where os.set_inheritable() is not supported? Can we announce that os.set_inheritable() is always available or not? Does such platform exist? (B) Should subprocess make the file descriptors of pass_fds inheritable? If yes, should it be done before or after the fork? If it is done after the fork and before exec, it only affects the child process, at least on Linux (the file descriptor is still non-inheritable in the parent process). (C) Should we handle standard streams (0: stdin, 1: stdout, 2: stderr) differently? For example, os.dup2(fd, 0) should make the file descriptor 0 (stdin) inheritable or non-inheritable? On Windows, os.set_inheritable(fd, False) fails (error 87, invalid argument) on standard streams (0, 1, 2) and copies of the standard streams (created by os.dup()). Victor

PEP 442 aftermath: module globals at shutdown
by Antoine Pitrou 01 Aug '13

01 Aug '13

Hello, PEP 442 has now been committed in time for testing in Alpha 1. This paves the way for the removal of another well-known annoyance: the behaviour of module globals at shutdown. Now that reference cycles aren't a barrier to object finalization anymore, we shouldn't need to set module globals to None before trying to reclaim modules. (and then, we don't need to cache global functions for use in finalizers, either) I have a patch to suppress the hack in http://bugs.python.org/issue18214 Once I get to add some tests, I would like to commit it soon too! Regards Antoine.
