[issue30165] faulthandler acquires lock from signal handler, can deadlock while crashing

Gregory P. Smith added the comment: Follow up note: Note that even with POSIX TLS in use, it isn't entirely safe. pthread_getspecific() as used by the posix thread code is not required to be async signal safe by the POSIX standard. :( The Linux glibc implementation thankfully does not use l

[issue30322] PyObject_GetIter does not behave as documented on dict objects

Raymond Hettinger added the comment: This from the help on dict.update(): | update(...) | D.update([E, ]**F) -> None. Update D from dict/iterable E and F. | If E present and has a .keys() method, does: for k in E: D[k] = E[k] | If E present and lacks .keys() method, does

[issue30323] concurrent.futures.Executor.map() consumes all memory when big generators are used

New submission from Klamann: The Executor's map() function accepts a function and an iterable that holds the function arguments for each call to the function that should be made. This iterable could be a generator, and as such it could reference data that won't fit into memory. The behaviour

[issue30165] faulthandler acquires lock from signal handler, can deadlock while crashing

STINNER Victor added the comment: > Note that even with POSIX TLS in use, it isn't entirely safe. I wrote faulthandler to collect debug data just before dying, when something already gone very bad, like a deadlock or a memory corruption. I didn't design faulthandler for correctness. If you ca

[issue30324] Error using newline='' when writing to CSV file

New submission from BeamPower: I am using the newline='' feature in my program to avoid the extra lines being placed between each line being written to a CSV file. This error is odd though... I used it before on a previous rev, and it worked fine. I think the CSV file writing feature has been a

[issue30308] Add code coverage for argument in random.shuffle

Cheryl Sabella added the comment: OK, I've removed the test for the negative values returned by random. In core-mentorship, David Murray had suggested adding a comment to document it as unexpected behavior. I had asked there because I wasn't quite sure what to do about it. Should I also lea

[issue30308] Add code coverage for argument in random.shuffle

Cheryl Sabella added the comment: I've also changed the test to use Mock for the random function. I'm new to mock, so I'm not sure if I did it right. Using a return_value seemed to be the best way to go. I didn't know if it was necessary to test if an incorrect function was sent in. --

[issue30325] Buildbot: send email notifications to buildbot-status@

New submission from STINNER Victor: I created a new mailing list to get email notifications when a buildbot starts failing (state change from green/success to red/failure). It seems like the buildbot config already sends email, but I don't see them in the archives of the python-checkins list?

[issue25652] collections.UserString.__rmod__() raises NameError

Jonathan Goble added the comment: Any decision on this? I recently played around and found a reasonable use case where UserString.__rmod__ does get called; run the attached userstringerror.py to see it in action. Basically, it seems the idea of UserString is to subclass it, tweak as desired,
