Pierre Sassoulas 514376fe29 [ruff] Add ruff's check and autofix existing issues 2024-02-02 15:18:38 +01:00
Pierre Sassoulas 4588653b24 Migrate from autoflake, black, isort, pyupgrade, flake8 and pydocstyle, to ruff
ruff is faster and handle everything we had prior.

isort configuration done based on the indication from
https://github.com/astral-sh/ruff/issues/4670, previousely based on
reorder-python-import (#11896)

flake8-docstrings was a wrapper around pydocstyle (now archived) that
explicitly asks to use ruff in https://github.com/PyCQA/pydocstyle/pull/658.

flake8-typing-import is useful mainly for project that support python 3.7
and the one useful check will be implemented in https://github.com/astral-sh/ruff/issues/2302

We need to keep blacken-doc because ruff does not handle detection
of python code inside .md and .rst. The direct link to the repo is
now used to avoid a redirection.

Manual fixes:
- Lines that became too long
- % formatting that was not done automatically
- type: ignore that were moved around
- noqa of hard to fix issues (UP031 generally)
- fmt: off and fmt: on that is not really identical
  between black and ruff
- autofix re-order in pre-commit from faster to slower

mypy: disallow untyped defs by default (#11862)
Change our mypy configuration to disallow untyped defs by default, which ensures *new* files added to the code base are fully typed.

To avoid having to type-annotate everything now, add `# mypy: allow-untyped-defs` to files which are not fully type annotated yet.

As we fully type annotate those modules, we can then just remove that directive from the top.

Ran Benita 0a20452f78 code: inline `Traceback.getcrashentry` into `ExceptionInfo._getreprcrash`
Since `Traceback.getcrashentry` takes the `ExceptionInfo`, it is not

mistakes by inlining it.

Ran Benita cc23ec91d0 code: stop storing weakref to ExceptionInfo on Traceback and TracebackEntry
TracebackEntry needs the excinfo for the `__tracebackhide__ = callback`
functionality, where `callback` accepts the excinfo.

Currently it achieves this by storing a weakref to the excinfo which
created it. I think this is not great, mixing layers and bloating the
objects.

Instead, have `ishidden` (and transitively, `Traceback.filter()`) take
the excinfo as a parameter.

Fix `pytrace=False` and `--tb=line` reports `None` (#10905)
Closes #10831.

This fixes a small bug where running tests that contained
`pytest.fail(pytrace=False)` with the `--tb=line` flag set results in
 an output of "None" in the Failures section of the output, and adds
 a test to ensure the behavior is correct.

Merge pull request #10907 from bluetech/empty-traceback
code: handle repr'ing empty tracebacks gracefully
2023-04-13 19:36:09 +03:00
Ran Benita e3b1799766 code: handle repr'ing empty tracebacks gracefully
By "empty traceback" I mean a traceback all of whose entries have been
filtered/cut/pruned out.

Currently, if an empty traceback needs to be repr'ed, the last entry
before the filtering is used instead (added in
accd962c9f).

Showing a hidden frame is not so good IMO. This commit does the
following instead:

1. Shows details of the exception.
2. Shows a message about how the full trace can be seen.

Example:

```
_____________ test _____________

E   ZeroDivisionError: division by zero
All traceback entries are hidden. Pass `--full-trace` to see hidden and internal frames.
```

Also handles `--tb=native`, though there the `--full-trace` bit is not
shown.

This commit contains some pieces from
431ec6d34e (which has been reverted).

Helps towards fixing issue # 1904.

Ran Benita 424c3eebde code: add ExceptionInfo.from_exception
The old-style `sys.exc_info()` triplet is redundant nowadays with
`(type(exc), exc, exc.__traceback__)`, and is beginning to get
soft-deprecated in Python 3.12.

Add a nicer API to ExceptionInfo which takes just the exc instead of the
triplet. There are already a few internal uses which benefit.

FormattedExcinfo.get_source: avoid crash when line number is out-of-bounds/negative
pytest could crash given pathological AST position attributes, which shouldn't happen when testing real Python code, but could happen when testing AST produced by e.g. Hylang.

Another example of the failure is in the nightly CI for the JAX project: https://github.com/google/jax/actions/runs/4607513902/jobs/8142126075

Drop attrs dependency, use dataclasses instead (#10669)
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

Ran Benita 0da4760715 code: accept any `os.PathLike[str]` in `Traceback.cut`
Before 7.0.0rc1, the function accepted `Union[str, py.path.local]`, and
`py.path.local` compares equal to the string path, so a user was able to
pass the path as a string and it would work. In 7.0.0rc1 we changed the
`py.path.local` to `Path` which doesn't compare equal to the string
path, which breaks compatibility (e.g. the `sybil` package).

This restores compatibility for this function by accepting any
`os.PathLike[str]` and only comparing the string representations.

Ran Benita c90fdc684b code: remove unneeded comparison eval wrapper
Given a `RecursionError` traceback, the `Traceback.recursionindex()`
method returns the index of the frame which started the recursion
(repeated set of frames). To do so it attempts to check whether two
frames are equivalent. Just checking the function/line is not enough
because the recursion variable(s) might differ (e.g. imagine the numeric
value in a recursive factorial implementation). So it also compares the
`f_locals` (local variables) of each frame for equivalence.

For some reason, the locals comparison is wrapped in an `eval` whose
purpose is to evaluate the comparison in one of the compared frame's
context (locals + globals in scope). However, I can not think of any way
in which the global scope could affect the evaluation. It would have an
affect when the locals are bound but that's already done. So this seems
unnecessary - remove it.

Ran Benita f2d65c85f4 code: export ExceptionInfo for typing purposes
This type is most prominent in `pytest.raises` and we should allow to
refer to it by a public name.

The type is not in a perfectly "exposable" state. In particular:

- The `traceback` property with type `Traceback` which is derived from
  the `py.code` API and exposes a bunch more types transitively. This
  stuff is *not* exported and probably won't be.

- The `getrepr` method which probably should be private.

But they're already used in the wild so no point in just hiding them
now.

The __init__ API is hidden -- the public API for this are the `from_*`
classmethods.
