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.
Previously, the expressions given to the `-m` and `-k` options were
evaluated with `eval`. This causes a few issues:
- Python keywords cannot be used.
- Constants like numbers, None, True, False are not handled correctly.
- Various syntax like numeric operators and `X if Y else Z` is supported
unintentionally.
- `eval()` is somewhat dangerous for arbitrary input.
- Can fail in many ways so requires `except Exception`.
The format we want to support is quite simple, so change to a custom
parser. This fixes the issues above, and gives us full control of the
format, so can be documented comprehensively and even be extended in the
future if we wish.
* tests: fix TypeError with test_mark_closest
It fails when trying to run it actually:
> TypeError: test_has_inherited() takes 0 positional arguments but 1 was given
* Fix testing/test_collection.py::TestCollector::test_getparent
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`.
It is a little too obscure IMO, but the reason I want to drop it is that
type checking has no hope of understanding such dynamic constructs.
The warning argument wasn't used.
