Speed up tests even more (#2205)
There's three optimizations in this commit:
1. Don't check if Black's output is stable or equivalant if no changes
were made in the first place. It's not like passing the same code
(for both source and actual) through black.assert_equivalent or
black.assert_stable is useful. It's not a big deal for the smaller
tests, but it eats a lot of time in tests/test_format.py since
its test cases are big. This is also closer to how Black works IRL.
2. Use a smaller file for `test_root_logger_not_used_directly` since
the logging it's checking happens during blib2to3's startup so the
file doesn't really matter.
3. If we're checking a file is formatting (i.e. test_source_is_formatted)
don't run Black over it again with `black.format_file_in_place`.
`tests/test_format.py::TestSimpleFormat.check_file` is good enough.

Speed up test suite via distributed testing (#2196)
* Speed up test suite via distributed testing
Since we now run the test suite twice, one with Python 2 and another
without, full test runs are getting pretty slow. Let's try to
fix that with parallization.
Also use verbose mode on CI since more logs is usually better since
getting more is quite literally impossible.
The main issue we'll face with this is we'll hit
https://github.com/pytest-dev/pytest-xdist/issues/620 sometimes
(although pretty rarely). I suppose we can test this and see if how bad
this bug is for us, and revert if necessary down the line.

Do not use gitignore if explicitly passing excludes (#2170)
Closes #2164.
Changes behavior of how .gitignore is handled. With this change, the rules in .gitignore are only used as a fallback if no exclusion rule is explicitly passed on the command line or in pyproject.toml. Previously they were used regardless if explicit exclusion rules were specified, preventing any overriding of .gitignore rules.
Those that depend only on .gitignore for their exclusion rules will not be affected. Those that use both .gitignore and exclude will find that exclude will act more like actually specifying exclude and not just another extra-excludes. If the previous behavior was desired, they should move their rules from exclude to extra-excludes.

Simplify GitHub Action entrypoint (#2119)
This commit simplifies entrypoint.sh for GitHub Actions by removing
duplication of args and black_args (cf. #1909).
The reason why #1909 uses the input id black_args is to avoid an overlap
with args, but this naming seems redundant. So let me suggest option
and src, which are consistent with CLI. Backward compatibility is
guaranteed; Users can still use black_args as well.

* Simplify GitHub Action entrypoint (#1909)
* Fix prettier
* Emit a warning message when `black_args` is used
This deprecation should be visible in GitHub Action's UI now.

Drop Travis CI and migrate Coveralls (#2186)
Travis CI for Open Source is shutting down in a few weeks so the queue
for jobs is insane due to lower resources. I'm 99.99% sure we don't need
it as our Test, Lint, Docs, Upload / Package, Primer, and Fuzz workflows
are all on GitHub Actions. So even though we *can* migrate to the .com
version with its 1000 free Linux minutes(?), I don't think we need to.
more information here:
- https://blog.travis-ci.com/oss-announcement
- https://blog.travis-ci.com/2020-11-02-travis-ci-new-billing
- https://docs.travis-ci.com/user/migrate/open-source-repository-migration
This commit does the following:
- delete the Travis CI configuration
- add to the GHA test workflows so coverage continues to be recorded
- tweaked coverage configuration so this wouldn't break
- remove any references to Travis CI in the docs (i.e. readme + sphinx
docs)
Regarding the Travis CI to GitHub Actions Coveralls transition, the
official action doesn't support the coverage files produced by coverage.py
unfornately. Also no, I don't really know what I am doing so don't @ me
if this breaks :p (well you can, but don't expect me to be THAT useful).
The Coveralls setup has two downfalls AFAIK:
- Only Linux runs are used because AndreMiras/coveralls-python-action
only supports Linux. Although this isn't a big issue since the Travis
Coveralls configuration only used Linux data too.
- Pull requests from an internal branch (i.e. one on psf/black) will be
marked as a push coverage build by Coveralls since our anti-duplicate-
workflows system runs under the push even for such cases.

Don't strip parens in assert / return with assign expr (#2143)
Black would previously strip the parenthesis away from statements like this these ones:
assert (spam := 12 + 1)
return (cheese := 1 - 12)
Which happens to be invalid code. Now before making the parenthesis invisible, Black
checks if the assignment expression's parent is an assert stamtment, aborting if True.
Raise, yield, and await are already handled fine.
I added a bunch of test cases from the PEP defining asssignment expressions (PEP 572).

Work around stability errors due to optional trailing commas (#2126)
Optional trailing commas put by Black become magic trailing commas on another
pass of the tool. Since they are influencing formatting around optional
parentheses, on rare occasions the tool changes its mind in terms of putting
parentheses or not.
Ideally this would never be the case but sadly the decision to put optional
parentheses or not (which looks at pre-existing "magic" trailing commas) is
happening around the same time as the decision to put an optional trailing
comma. Untangling the two proved to be impractically difficult.
This shameful workaround uses the fact that the formatting instability
introduced by magic trailing commas is deterministic: if the optional trailing
comma becoming a pre-existing "magic" trailing comma changes formatting, the
second pass becomes stable since there is no variable factor anymore on pass 3,
4, and so on.
For most files, this will introduce no performance penalty since `--safe` is
already re-formatting everything twice to ensure formatting stability. We're
using this result and if all's good, the behavior is equivalent. If there is
a difference, we treat the second result as the binding one, and check its
sanity again.

Recommend B950 + 88 char limit instead of 80 (#2050)
[The section about line length][1] was contradictory.
On one side, it said:
> Black will try to respect that [line length limit]. However, sometimes it won't be able to without breaking other rules. In those rare cases, auto-formatted code will exceed your allotted limit.
So black doesn't guarantee that your code is formatted at 88 chars, even when configured with `--line-length=88` (default). Black uses this limit as a "hint" more than a "rule".
OTOH, it also said:
> If you're using Flake8, you can bump max-line-length to 88 and forget about it. Alternatively, use Bugbear's B950 warning instead of E501 and keep the max line length at 80 which you are probably already using.
But that's not true. You can't "forget about it" because Black sometimes won't respect the limit. Both E501 at 88 and B950 at 80 behave the same: linter error at 89+ length. So, if Black happens to decide that a line of code is better at 90 characters that some other fancy style, you land on a unlucky situation where both tools will fight.
So, AFAICS, the best way to align flake8 and black is to:
1. Use flake8-bugbear
2. Enable B950
3. Disable E501
4. Set `max-line-length = 88`
This way, we also tell flake8 that 88 limit is a "hint" and not a "rule". The real rule will be 88 + 10%. If black decides that a line fits better in 97 characters than in 88 + some formatting, _that_ probably means your code has a real problem.
To avoid further confusion, I change the official recommendation here.

defeats the point of the test.
