Description Nicolas Pomarède 2022-04-19 15:10:17 CEST

Description of problem:

current version 6.12 of getmail has a bug where getmail will crash when its forked child will take more than 3 sec to get the mails.

See here : https://github.com/getmail6/getmail6/issues/59

single fix is here : https://github.com/getmail6/getmail6/commit/b2d82a41ae73476c42a27f9c6764c0415bca5833 and is part of getmail 6.13

patching the 6.12 file manually indeed fixes the crash

Please update getmail to a more recent version (latest is 6.18.6)

Also note that this getmail is in fact getmail6 which is an un-official fork of getmail 5 to support python3 :

https://pyropus.ca./software/getmail/documentation.html#python3-getmail6

unfortunately, there's not much mageia can do about this if python2 support is dropped completely.

Thank you for the researched and helpful report.
We do in fact have (after 6.15 & 6.18.5) 6.18.6 in Cauldron. We did not have 6.13.

Assigning this to solbu who did 6.12 and those more recent versions.

Additional bug found with this 6.12 version : getmail6 gets killed when waiting "forever" according to the code :

stopped waiting for child 51990getmailrc: operation error (child pid 51990 killed by signal 8)

This is described in https://github.com/getmail6/getmail6/pull/65 and fixed in getmail 6.14. Applying the patch manually to 6.12 fixes the issue.

So getmail for mageia 8 should be updated to at least 6.14

I have uploaded a patched version to mga8 core/updates_testing

getmail-6.12-1.1.mga8

Please test.

Status: NEW => ASSIGNED

In getmail-6.12-1.1.mga8 getmailcore/baseclasses.py is still the same as before, only baseclasses.cpython-38.pyc is different.

Did you forget to patch the .py source file too ?

This is how it looks like in my own patched version after applying changes for issues 59 and 65 :

    def _wait_for_child(self, childpid):
        self.__child_exited.acquire()
        if not self.__child_exited.wait(60):
            raise getmailOperationError('waiting child pid %d timed out'
                                        % childpid)
        self.__child_exited.release()
[...]
