* [3.9] bpo-43913: Fix bugs in cleaning up classes and modules in unittest. ↵Serhiy Storchaka2021-08-304-69/+719
| | | | | | | | | | | | | | | | | | | (GH-28006) (GH-28071) * Functions registered with addModuleCleanup() were not called unless the user defines tearDownModule() in their test module. * Functions registered with addClassCleanup() were not called if tearDownClass is set to None. * Buffering in TestResult did not work with functions registered with addClassCleanup() and addModuleCleanup(). * Errors in functions registered with addClassCleanup() and addModuleCleanup() were not handled correctly in buffered and debug modes. * Errors in setUpModule() and functions registered with addModuleCleanup() were reported in wrong order. * And several lesser bugs..

* bpo-45001: Make email date parsing more robust against malformed input ↵Miss Islington (bot)2021-08-263-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-27946) (GH-27973) Various date parsing utilities in the email module, such as email.utils.parsedate(), are supposed to gracefully handle invalid input, typically by raising an appropriate exception or by returning None. The internal email._parseaddr._parsedate_tz() helper used by some of these date parsing routines tries to be robust against malformed input, but unfortunately it can still crash ungracefully when a non-empty but whitespace-only input is passed. This manifests as an unexpected IndexError. In practice, this can happen when parsing an email with only a newline inside a ‘Date:’ header, which unfortunately happens occasionally in the real world. Here's a minimal example: $ python Python 3.9.6 (default, Jun 30 2021, 10:22:16) [GCC 11.1.0] on linux Type "help", "copyright", "credits" or "license" for more information. >>> import email.utils >>> email.utils.parsedate('foo') >>> email.utils.parsedate(' ') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python3.9/email/_parseaddr.py", line 176, in parsedate t = parsedate_tz(data) File "/usr/lib/python3.9/email/_parseaddr.py", line 50, in parsedate_tz res = _parsedate_tz(data) File "/usr/lib/python3.9/email/_parseaddr.py", line 72, in _parsedate_tz if data[0].endswith(',') or data[0].lower() in _daynames: IndexError: list index out of range The fix is rather straight-forward: guard against empty lists, after splitting on whitespace, but before accessing the first element.

* bpo-44852: Support filtering over warnings without a set message (GH-27793) ↵Miss Islington (bot)2021-08-181-4/+5
| | | | | | | | | | | | | | | (GH-27810) Additional improvements: - messages which were compiled regular expressions aren't unpacked back into strings for unmatched warnings; - removed unnecessary "if tokens:" check (there's one before the for loop); - took `endswith` calculation out of the for loop.
