Since pytest now requires Python>=3.7, we can use the stdlib attrs
clone, dataclasses, instead of the OG package.
attrs is still somewhat nicer than dataclasses and has some extra
functionality, but for pytest usage there's not really a justification
IMO to impose the extra dependency on users when a standard alternative
exists.

fall back to native when handeling to exception groups
* Typed ExceptionGroupTypes and changed to BaseExceptionGroup, fixed exceptionchain (excinfo->excinfo_, set reprcrash. Extended tests, though they're wip.
* added exceptiongroup to pre-commit-config, moved away from tuple to directly defining BaseExceptionGroup, added block comment, added match line for inner exception, changked mark.skipif to importorskip to not need top-level import, changed tox.ini a bit - only uncovered should now be py37 without exceptiongroup, due to hypothesis
* added py311-exceptiongroup to github CI, exceptiongroup is now a hard dependency on py<3.11, renamed bad variable names
* added use_coverage to ubuntu-py311
* import BaseExceptionGroup with explicit version check instead of try/catch
* removed from CI, added comments to tox and pre-commit
this issues is less likely to hit due to the recent regendoc release
which includes a wheel
* migrate to setuptools_scm 6.3.2
* use SETUPTOOLS_SCM_PRETEND_VERSION_FOR_PYTEST
the best practice is to only `<` when you know something is broken, and even then prefer `!=` assuming it will be fixed upstream for maximum compatibility
The `Sphinx-PyPI-upload` tool the section corresponds to hasn't been updated since 2009, and the new (c. 2018) PyPI doesn't support documentation uploads anyway.
Warnings like this:
python3.9/site-packages/setuptools/dist.py:634: UserWarning: Usage of
dash-separated 'upload-dir' will not be supported in future versions.
Please use the underscore name 'upload_dir' instead
We run mypy through pre-commit, and we don't keep duplicate targets in
tox for all of the other linters. Since this adds some (small)
maintenance overhead, remove it.
This makes mypy raise an error whenever it detects code which is
statically unreachable, e.g.
x: int
if isinstance(x, str):
... # Statement is unreachable [unreachable]
This is really neat and finds quite a few logic and typing bugs.
Sometimes the code is intentionally unreachable in terms of types, e.g.
raising TypeError when a function is given an argument with a wrong
type. In these cases a `type: ignore[unreachable]` is needed, but I
think it's a nice code hint.
This prevents referring to a generic type without filling in its generic
type parameters.
The FixtureDef typing might need some more refining in the future.
In Python, if module A defines a name `name`, and module B does `import
name from A`, then another module C can `import name from B`.
Sometimes it is intentional -- module B is meant to "reexport" `name`.
But sometimes it is just confusion/inconsistency on where `name` should
be imported from.
mypy has a flag `--no-implicit-reexport` which puts some order into
this. A name can only be imported from a module if
1. The module defines the name
2. The module's `__all__` includes the name
3. The module imports the name as `from ... import .. as name`.
This flag is included in mypy's `--strict` flag.
I like this flag, but I realize it is a bit controversial, and in
particular item 3 above is a bit unfriendly to contributors who don't
know about it. So I didn't intend to add it to pytest.
But while investigating issue 7589 I came upon mypy issue 8754 which
causes `--no-implicit-reexport` to leak into installed libraries and
causes some unexpected typing differences *in pytest* if the user uses
this flag.
Since the diff mostly makes sense, let's just conform to it.
We barely use it; the couple places that do are not really worth the
extra dependency, I think the code is clearer without it.
Also simplifies one (regular) itertools usage.
Also improves a check and an error message in `pytest.raises`.
This option checks even functions which are not annotated. It's a good
step to ensure that existing type annotation are correct.
In a Pareto fashion, the last few holdouts are always the ugliest,
beware.
Running `pytest | head -1` and similar causes an annoying error to be
printed to stderr:
Exception ignored in: <_io.TextIOWrapper name='<stdout>' mode='w' encoding='utf-8'>
BrokenPipeError: [Errno 32] Broken pipe
(or possibly even a propagating exception in older/other Python versions).
The standard UNIX behavior is to handle the EPIPE silently. To
recommended method to do this in Python is described here:
https://docs.python.org/3/library/signal.html#note-on-sigpipe
It is not appropriate to apply this recommendation to `pytest.main()`,
which is used programmatically for in-process runs. Hence, change
pytest's entrypoint to a new `pytest.console_main()` function, to be
used exclusively by pytest's CLI, and add the SIGPIPE code there.
Fixes#4375.
Add a very lax mypy configuration, add it to tox -e linting, and
fix/ignore the few errors that come up. The idea is to get it running
before diving in too much.
This enables:
- Progressively adding type annotations and enabling more strict
options, which will improve the codebase (IMO).
- Annotating the public API in-line, and eventually exposing it to
library users who use type checkers (with a py.typed file).
Though, none of this is done yet.
