* Improve Python 2 only syntax detection
First of all this fixes a mistake I made in Python 2 deprecation PR
using token.* to check for print/exec statements. Turns out that
for nodes with a type value higher than 256 its numeric type isn't
guaranteed to be constant. Using syms.* instead fixes this.
Also add support for the following cases:
print "hello, world!"
exec "print('hello, world!')"
def set_position((x, y), value):
pass
try:
pass
except Exception, err:
pass
raise RuntimeError, "I feel like crashing today :p"

* Update CHANGES.md for 21.10b0 release
* Update version in docs/usage_and_configuration/the_basics.md
* Also update docs/integrations/source_version_control.md ...
- Install build-essential to avoid build issues like #2568 when dependencies don't have prebuilt wheels available
- Use multi-stage build instead of trying to purge packages and cache from the image
Copying `/root/.local/` installs only black's built Python dependencies (< 20 MB).
So the image is barely larger than python:3-slim base image
* Prepare for Python 2 depreciation
- Use BlackRunner and .stdout in command line test
So the next commit won't break this test. This is in its own commit so
we can just revert the depreciation commit when dropping Python 2
support completely.
* Deprecate Python 2 formatting support
Existing test was actually running a full black-primer
run which could be slow. This goes from 8 seconds to
0.4 seconds on my machine.
Needed to move to top level scope to leverage the caplog
feature of pytest in order to test that the command line
was parsing the bogus arguments and dumping to stderr.
* fix: allow tests to be run from the tests/ directory
* fix: try fixing windows build with MarcoGorelli's suggestion
* Windows hotfix + better respect test's spirit

If the individual failures are verbose, it's useful to have
the summary at the end. Otherwise, it can be really difficult
to figure out which projects have an issue.
It currently prints both ASTs - this also
adds the line diff, making it much easier to visualize
the changes as well. Not too verbose since it's only a diff.
Fixes#2394. Eventually fixes#517.
This is essentially @pradyunsg's suggestion from #2394. I suggest that at the
same time we start the formal stability policy, we take a few other disruptive steps
and drop Python 2 and the "b" marker.

The main goals of this commit include:
* improving consistency on how strict the test suite is -- Jelle has
seen cases where a test did not fail to an incomplete test setup
even though it should've
* simplifying tests for both ease of creation and reading via
parametrization and helpers
* reorganizing the test suite by grouping more tests
* dropping test suite dependencies that aren't strictly necessary
The test suite could definitely do with more refactoring, but this is a
good first pass. Anyway it would've gotten too big to review effectively
if I did continue on this PR.
Commit history before squash merge:
* Drop parameterized dep and refactor format tests
Since the test suite is already using pytest-only features we can drop
the parameterized test dependency in favour of pytest's own offering.
I also added an utility function called assert_format that makes it
even easier to verify Black formats some code correctly. We already
have great tooling if the case is very simple in test_format.py but
any sort of complication makes it hard to use. Also if you're writing
a non-standard test case, you have to be careful to include all of
the steps so issues don't go undetected. assert_format aims to
1) improve consistency, 2) avoid wasted CPU cycles, and 3) avoid
logical errors that hide issues.
Finally, quite a few tests were either moved and/or simplified with
the new setup.
* Move file collection tests
* Add assert_collected_sources helper function
Testing source collection involves a lot of repetitive boilerplate,
something that black.files.get_sources's signature does not help with.
So to cut down on boilerplate like `report=black.Report()` I added
a convenience function to tests/test_black.py which wraps
black.get_sources. Its signature is designed to be much more lax to
make it much easier to use. Somehow this leads to cutting 100 lines!
Also IMO the test cases are much easier to read since it's more
declarative than really procedural now.
* Run isort on some test files
* Move cache tests
* Use pytest-style asserts & add parametrization
* Drop now unnecessary test dependencies
*pytest-cases might be interesting for further refactoring but I
haven't been able to wrap my head around it for the time being. We
can always revisit anyway.

Project packaging is using TOML due to pyproject.toml but fails to
mention it, causing installation failures with newer setuptools-scm 6.3.0.

* Fix missing toml extra
Fixed breakage uncovered by setuptools-scm 6.3.0 where installation
would fail for project that missed to mention the toml extra.

Add new platformdirs dependencies as hidden imports when creating
PyInstaller-based binaries.
platformdirs imports the module for each platform dynamically, which
PyInstaller is unable to correctly detect for packing. By adding the
modules as hidden imports, we are telling PyInstaller to include the
modules in the packaged binary.
This issue seems to have been introduce when switching to platformdirs
in #2375. fixes#2464

re. import, the ipynb code was assuming that typing-extensions would
always be available, but that's not the case! There's an environment
marker on the requirement meaning it won't get installed on 3.10 or
higher. The test suite didn't catch this issue since aiohttp pulls in
typing-extensions unconditionally.
Hopefully my first release doesn't end up in flames 🔥
Commit history before merge:
* Prepare CHANGES.md for release 21.8b0
* I need to add a check for this too.
The setuptools-scm dependency in setup.cfg did not have a version
specified, leading to the issues described in #2449 after a faulty release
of setuptools-scm was published. To avoid this issue in the future, the
last version before that faulty update is now pinned.
Commit history before merge:
* Pin setuptools-scm dependency version (#2449)
* Update CHANGES.md
* Let's pin in pyproject.toml too
Mostly since it's non-build-backend specific configuration and more
widely standardized file. Not sure what benefits pinning in setup.cfg
gives us on top of pyproject.toml but I'd rather not find out during
the release that is supposed to happen today 😉

Implementation stolen from PR davidhalter/parso#162. Thanks parso!
I could add support for these newer syntactical constructs in the
target version detection logic, but until I get diff-shades up
and running I don't feel very comfortable adding the code.
