We have a use case for this in the next commit.
The name can be obtained by using `manager.get_name(plugin)`, however
this is currently O(num plugins) in pluggy, which would be good to
avoid. Besides, it seems generally useful.
This removes one thing that directory collectors need to worry about.
This adds one hook dispatch per `__pycache__` file, but I think it's
worth it for consistency.
(Diff better viewed ignoring whitespace)
Since e1c66ab0ad, conftest loading is
handled at the directory level before sub-nodes are collected, so there
is no need for the doctest plugin to handle it specially.
This was probably the case even before
e1c66ab0ad, but I haven't verified this.
This is a useful addition to the existing `listchain`. While `listchain`
returns top-to-bottom, `iterparents` is bottom-to-top and doesn't require
an internal full iteration + `reverse`.
Since we're removing nose support, let's also drop support for this
attribute.
From doing a code search on github, this seems completely unused outside
of nose, except for some projects which used to use it, but no longer
do.
Refs #11662.
--- Problem
Each fixture definition has a "visibility", the `FixtureDef.baseid`
attribute. This is nodeid-like string. When a certain `node` requests a
certain fixture name, we match node's nodeid against the fixture
definitions with this name.
The matching currently happens on the *textual* representation of the
nodeid - we split `node.nodeid` to its "parent nodeids" and then check
if the fixture's `baseid` is in there.
While this has worked so far, we really should try to avoid textual
manipulation of nodeids as much as possible. It has also caused problem
in an odd case of a `Package` in the root directory: the `Package` gets
nodeid `.`, while a `Module` in it gets nodeid `test_module.py`. And
textually, `.` is not a parent of `test_module.py`.
--- Solution
Avoid this entirely by just checking the node hierarchy itself. This is
made possible by the fact that we now have proper `Directory` nodes
(`Dir` or `Package`) for the entire hierarchy.
Also do the same for `_getautousenames` which is a similar deal.
The `iterparentnodeids` function is no longer used and is removed.
Instead of modifying user objects like modules and classes that we
really shouldn't be touching, use the new `_register_fixture` internal
API to do it directly.
Add a function on the `FixtureManager` to register a fixture with
pytest. Currently this can only be done through `parsefactories`.
My aim is to eventually make something like this available to plugins,
as it's a pretty common need.
