This is a more sensible interface for matchnodes.
This also fixes a sort-of bug where a recursive call to matchnodes
raises NoMatch which would terminate the entire tree, even if other
branches may find a match. Though I don't think it's actually possible.
This reverts commit f10ab021e2.
The commit was good in that it removed a non-trivial amount of code
duplication. However it was done in the wrong layer (nodes.py) and split
up a major part of the collection (the filesystem traversal) to a
separate class making it harder to understand.
We should try to reduce the duplication, but in a more appropriate
manner.
The path part of a `<path>::part1::part2` style collection argument must
be a file, not a directory.
Previously this crashed with an uncool assert "invalid arg".
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.
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.
`os.scandir()`, introduced in Python 3.5, is much faster than
`os.listdir()`. See https://www.python.org/dev/peps/pep-0471/.
It also has a `DirEntry` which can be used to further reduce syscalls in
some cases.
Part of reducing dependency on `py`. Also enables upcoming improvements.
In cases where there are simpler alternatives (in tests), I used those.
What's left are a couple of uses in `_pytest.main` and `_pytest.python`
and they only have modest requirements, so all of the featureful code
from py is not needed.
It should only return `True` when something is to be ignored, not
`False` otherwise typically.
This caused e.g. bad interaction with the cacheprovider (before
https://github.com/pytest-dev/pytest/pull/6448).
Mypy currently is unable to handle assigning attributes on function:
https://github.com/python/mypy/issues/2087.
pytest uses this for the outcome exceptions -- `pytest.fail.Exception`,
`pytest.exit.Exception` etc, and this is the canonical name by which they
are referred.
Initially we started working around this with type: ignores, and later
by switching e.g. `pytest.fail.Exception` with the direct exception
`Failed`. But this causes a lot of churn and is not as nice. And I also
found that some code relies on it, in skipping.py:
def pytest_configure(config):
if config.option.runxfail:
# yay a hack
import pytest
old = pytest.xfail
config._cleanup.append(lambda: setattr(pytest, "xfail", old))
def nop(*args, **kwargs):
pass
nop.Exception = xfail.Exception
setattr(pytest, "xfail", nop)
...
So it seems better to support it. Use a hack to make it work. The rest
of the commit rolls back all of the workarounds we added up to now.
`pytest.raises.Exception` also exists, but it's not used much so I kept
it as-is for now.
Hopefully in the future mypy supports this and this ugliness can be
removed.
ExitCode is used in several internal modules and hooks and so with type
annotations added, needs to be imported a lot.
_pytest.main, being the entry point, generally sits at the top of the
import tree.
So, it's not great to have ExitCode defined in _pytest.main, because it
will cause a lot of import cycles once type annotations are added (in
fact there is already one, which this change removes).
Move it to _pytest.config instead.
_pytest.main still imports ExitCode, so importing from there still
works, although external users should really be importing from `pytest`.
Mypy complains about this once the function is typed:
src/_pytest/main.py:85: error: "_addoption" of "OptionGroup" does not return a value
src/_pytest/main.py:133: error: "addoption" of "OptionGroup" does not return a value
Previously, this cache was used with 3 different and mutually exclusive
key-type -> value-type combinations. Mypy can't properly type this. It's
also quite confusing.
Split to 3 different dicts instead.
Previously, _initialparts was a list whose first item was a
`py.path.local` and the rest were `str`s. This is not something that
mypy is capable of modeling. The type `List[Union[str, py.path.local]]`
is too broad and would require asserts for every access.
Instead, make each item a `Tuple[py.path.local, List[str]]`. This way
the structure is clear and the types are accurate.
To make sure any users who might have been accessing this (private)
field will not break silently, change the name to _initial_parts.
Harden one test where it is tested.
