Regressed in 6.1.0 in 62e249a1f9.
The `x` is an `str` but is expected to be a `pathlib.Path`. Not caught
by mypy because `config.getini()` returns `Any`.
Fix by just removing the `bestrelpath` call:
- testpaths are always relative to the rootdir, it thus would be very
unusual to specify an absolute path there.
- The code was wrong even before the regression: `py.path.local`'s
`bestrelpath` function expects a `py.path.local`, not an `str`. But it
had some weird `try ... except AttributeError` fallback which just
returns the argument, i.e. it was a no-op. So there is no behavior
change.
- It seems reasonable to me to just print the full path if that's what
the ini specifies.
When switching from py.path.local to pathlib (70f3ad1c1f),
`local.parts(reverse=True)` was translated incorrectly, leading to the
wrong rootdir being determined in some non-trivial cases where parent
directories have config files as well.
This indicates at least for people using type checkers that these
classes are not designed for inheritance and we make no stability
guarantees regarding inheritance of them.
Currently this doesn't show up in the docs. Sphinx does actually support
`@final`, however it only works when imported directly from `typing`,
while we import from `_pytest.compat`.
In the future there might also be a `@sealed` decorator which would
cover some more cases.
For decorated functions, the lineno of the FunctionDef AST node points
to the `def` line, not to the first decorator line. On the other hand,
in code objects, the `co_firstlineno` points to the first decorator
line.
Assertion rewriting inserts some imports to code it rewrites. The
imports are inserted at the lineno of the first statement in the AST. In
turn, the code object compiled from the rewritten AST uses the lineno of
the first statement (which is the first inserted import).
This means that given a module like this,
```py
@foo
@bar
def baz(): pass
```
the lineno of the code object without assertion rewriting
(`--assertion=plain`) is 1, but with assertion rewriting it is 3.
And *this* causes some issues for the exception repr when e.g. the
decorator line is invalid and raises during collection. The code becomes
confused and crashes with
INTERNALERROR> File "_pytest/_code/code.py", line 638, in get_source
INTERNALERROR> lines.append(space_prefix + source.lines[line_index].strip())
INTERNALERROR> IndexError: list index out of range
Fix it by special casing decorators. Maybe there are other cases like
this but off hand I can't think of another Python construct where the
lineno of the item would be after its first line, and this is the only
such issue we have had reported.
Warnings are a central part of Python, so much that Python itself has
command-line and environtment variables to handle warnings.
By moving the concept of warning handling into Config, it becomes natural to
filter warnings issued as early as possible, even before the "_pytest.warnings"
plugin is given a chance to spring into action. This also avoids the weird
coupling between config and the warnings plugin that was required before.

When a Python object (module/class/instance) is collected, for each name
in `obj.__dict__` (and up its MRO) the pytest_pycollect_makeitem hook is
called for potentially creating a node for it.
These Python objects have a bunch of builtin attributes that are
extremely unlikely to be collected. But due to their pervasiveness,
dispatching the hook for them ends up being mildly expensive and also
pollutes PYTEST_DEBUG=1 output and such.
Let's just ignore these attributes.
On the pandas test suite commit 04e9e0afd476b1b8bed930e47bf60e,
collect only, irrelevant lines snipped, about 5% improvement:

In ff8b7884e8 NOTSET was changed to a
singleton enum, which ended up unexpectedly triggering a code path in ID
generation which checks for `isinstance(Enum)`.
Add an explicit case for it, which is not too bad anyway.
The `CaptureManager.global_and_fixture_disabled()` context manager (and
`CaptureFixture.disabled()` which calls it) did `suspend(); ...;
resume()` but if the capturing was already suspended, the `resume()`
would resume it when it shouldn't.
This caused caused some messages to be swallowed when `--log-cli` is
used because it uses `global_and_fixture_disabled` when capturing is not
necessarily resumed.
This fixes an issue where pylint complains about missing implementations
of abstract methods in subclasses of `File` which only override
`collect()` (as they should).
It is also cleaner and makes sense, these methods really don't need to
be overridden.
The previous methods defined directly on `FSCollector` and `Package` are
deprecated, to be removed in pytest 7.
See commits e2934c3f8c and
f10ab021e2 for reference.
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`.
Part of the effort to reduce dependency on the py library.
Besides that, py.xml implements its own XML serialization which is
pretty scary.
I tried to keep the code with minimal changes (though it could use some
cleanups). The differences in behavior I have noticed are:
- Attributes in the output are not sorted.
- Some unneeded escaping is no longer performed, for example escaping
`"` to `"` in a text node.
Setting log_level via the CLI or .ini will control the log level of the
report that is dumped upon failure of a test.
If caplog modified the log level during the execution of that test, it
should not impact the level that is displayed upon failure in the
"captured log report" section.

ran:
- rebased
- reused handler
- changed store keys also to "caplog_handler_*"
- added changelog
all bugs are mine :)

`TerminalWriter`, imported recently from `py`, contains its own
incomplete wcwidth (`char_with`/`get_line_width`) implementation. The
`TerminalReporter` also needs this, but uses the external `wcwidth`
package.
This commit brings the `TerminalWriter` implementation up-to-par with
`wcwidth`, moves to implementation to a new file `_pytest._io.wcwidth`
which is used everywhere, and removes the dependency.
The differences compared to the `wcwidth` package are:
- Normalizes the string before counting.
- Uses Python's `unicodedata` instead of vendored Unicode tables. This
means the data corresponds to the Python's version Unicode version
instead of the `wcwidth`'s package version.
- Apply some optimizations.
pytest.fixture() can be used either as
@pytest.fixture
def func(): ...
or as
@pytest.fixture()
def func(): ...
or (while maybe not intended)
func = pytest.fixture(func)
so it needs to inspect internally whether it got a function in the first
positional argument or not.
Previously, there were was oddity. In the following,
func = pytest.fixture(func, autouse=True)
# OR
func = pytest.fixture(func, parms=['a', 'b'])
The result is as if `func` wasn't passed.
There isn't any reason for this special that I can understand, so remove
it.
