* bpo-36044: Reduce number of unit tests run for PGO build (GH-14702)Neil Schemenauer2019-07-227-4/+96
| | | | | | | | | | | | Reduce the number of unit tests run for the PGO generation task. This speeds up the task by a factor of about 15x. Running the full unit test suite is slow. This change may result in a slightly less optimized build since not as many code branches will be executed. If you are willing to wait for the much slower build, the old behavior can be restored using './configure [..] PROFILE_TASK="-m test --pgo-extended"'. We make no guarantees as to which PGO task set produces a faster build. Users who care should run their own relevant benchmarks as results can depend on the environment, workload, and compiler tool chain.

* Clarify that plistlib's load and dump functions take a binary file object ↵Collin Styles2019-07-141-3/+3
| | | | | | | | | | | (GH-9825) The documentation says that the fp parameter to plistlib.load "should be a readable and binary file object" but the docstring only mentions that it should be readable. Similarly, plistlib.dump's docstring only mentions "writable". This commit clarifies that fp should also be binary. https://docs.python.org/3/library/plistlib.html#plistlib.load https://docs.python.org/3/library/plistlib.html#plistlib.dump

* bpo-26967: fix flag grouping with allow_abbrev=False (GH-14316)Zac Hatfield-Dodds2019-07-145-1/+28
| | | | | | | | | | | The `allow_abbrev` option for ArgumentParser is documented and intended to disable support for unique prefixes of --options, which may sometimes be ambiguous due to deferred parsing. However, the initial implementation also broke parsing of grouped short flags, such as `-ab` meaning `-a -b` (or `-a=b`). Checking the argument for a leading `--` before rejecting it fixes this. This was prompted by pytest-dev/pytest#5469, so a backport to at least 3.8 would be great :smile: And this is my first PR to CPython, so please let me know if I've missed anything! https://bugs.python.org/issue26967

| | | | | | | | | | | | | | | | | | | | | mailbox.Maildir (GH-1163) Hi, I've faced an issue w/ `mailbox.Maildir()`. The case is following: 1. I create a folder with `tempfile.TemporaryDirectory()`, so it's empty 2. I pass that folder path as an argument when instantiating `mailbox.Maildir()` 3. Then I receive an exception happening because "there's no such file or directory" (namely `cur`, `tmp` or `new`) during interaction with Maildir **Expected result:** subdirs are created during `Maildir()` instance creation. **Actual result:** subdirs are assumed as existing which leads to exceptions during use. **Workaround:** remove the actual dir before passing the path to `Maildir()`. It will be created automatically with all subdirs needed. **Fix:** This PR. Basically it adds creation of subdirs regardless of whether the base dir existed before. https://bugs.python.org/issue30088
