Add a new hook , `pytest_markeval_namespace` which should return a dictionary.
This dictionary will be used to augment the "global" variables available to evaluate skipif/xfail/xpass markers.
Pseudo example
``conftest.py``:
.. code-block:: python
def pytest_markeval_namespace():
return {"color": "red"}
``test_func.py``:
.. code-block:: python
@pytest.mark.skipif("color == 'blue'", reason="Color is not red")
def test_func():
assert False
Python 3.7 changes the pyc format by adding a flags byte. Even though it
is not necessary for us to match it, it is nice to be able to read pyc
files we emit for debugging the rewriter.
Update our custom pyc files to use that format. We write flags==0
meaning we still use the mtime+size format rather the newer hash format.
In order to allow users to type annotate fixtures they request, the
types need to be imported from the `pytest` namespace. They are/were
always available to import from the `_pytest` namespace, but that is
not guaranteed to be stable.
These types are only exported for the purpose of typing. Specifically,
the following are *not* public:
- Construction (`__init__`)
- Subclassing
- staticmethods and classmethods
We try to combat them being used anyway by:
- Marking the classes as `@final` when possible (already done).
- Not documenting private stuff in the API Reference.
- Using `_`-prefixed names or marking as `:meta private:` for private
stuff.
- Adding a keyword-only `_ispytest=False` to private constructors,
warning if False, and changing pytest itself to pass True. In the
future it will (hopefully) become a hard error.
Hopefully that will be enough.
When --doctest-modules is used, an `__init__.py` file is not a `Package`
but a `DoctestModule`, but some collection code assumed that
`__init__.py` implies a `Package`. That code caused only a single test
to be collected in the scenario in the subject.
Tighten up this check to explicitly check for `Package`. There are
better solutions, but for another time.

We want to export `pytest.MonkeyPatch` for the purpose of
type-annotating the `monkeypatch` fixture. For other fixtures we export
in this way, we also make direct construction of them (e.g.
`MonkeyPatch()`) private. But unlike the others, `MonkeyPatch` is also
widely used directly already, mostly because the `monkeypatch` fixture
only works in `function` scope (issue #363), but also in other cases. So
making it private will be annoying and we don't offer a decent
replacement yet.
So, let's just make direct construction public & documented.
When pytest was run on a directory containing a recursive symlink it failed
with ELOOP as the library was not able to determine the type of the
direntry:
src/_pytest/main.py:685: in collect
if not direntry.is_file():
E OSError: [Errno 40] Too many levels of symbolic links: '/home/florian/proj/pytest/tests/recursive'
This is fixed by handling ELOOP and other errors in the visit function in
pathlib.py, so the entries whose is_file() call raises an OSError with the
pre-defined list of error numbers will be exluded from the result.
The _ignore_errors function was copied from Lib/pathlib.py of cpython 3.9.
Fixes#7951
