`_set_initial_conftests` could break on some systems if a very long
option was passed, because the `Path.exists()` call raises an
`OSError` instead of returning `False`.
Fix#10169
Fixes a pytest-xdist regression after
762bb61562 (not yet released).
pytest-xdist patches sys.stderr with an object which doesn't have
`encoding`. Strictly speaking, this should be fixed there (or more
precisely, in execnet), but it will drop support for older versions
which don't want.
But in any case, the fix turns out to simplify the code, using FD
support added in Python 3.5, so it's good anyway!

* faulthandler: fix an EncodingWarning
* _py/path: tiny change to `ensure` to silence EncodingWarning
We're not supposed to diverge here, but make this change to fix an
unavoidable EncodingWarning that is otherwise raised in pytest's test
suite. The behavior should be exactly the same besides the warning,
hopefully that won't cause confusion.
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.
The problem is that we would loop over all directories of the basetemp directory searching for dead symlinks, for each test, which would compound over the test session run.
Doing the cleanup just once, at the end of the session, fixes the problem.
Fix#10896
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.

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.
Fix#10875
Without this, fails with
```
...
E AttributeError: 'TestCaseFunction' object has no attribute 'addDuration'
...
E RuntimeWarning: TestResult has no addDuration method
```
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

Nowadays, the prepend and append import modes use importlib.import_module() instead of __import__().
There was a phrase “which avoids having to use `__import__`”, in which I couldn’t just replace `__import__` by `importlib.import_module` because the latter is used (in insert_missing_modules()) also when using importlib mode. Therefore I removed the part from the sentence.
This makes it possible to correlate pytest stages with external events, and also makes it readable when TestReports are exported externall (for example with pytest-reportlog).

Instead of `SysCapture`/`FDCapture` inheriting from
`SysCaptureBinary`/`FDCaptureBinary`, have both inherit from a common
`SysCaptureBase`/`FDCaptureBase`. This fixes a Liskov substitution
violation.
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.
