This commit only refactors, it does not change or add functionality yet. Public
API is retained. Reason or refactoring:
User provided parameter IDs (e.g. Metafunc.parametrize(ids=...)) had so far
only been used to calculate a unique test ID for each test invocation. That
test ID was a joined string where each parameter contributed some partial ID.
We're soon going to reuse functionality to generate parameter keys for
reorder_items and FixtureDef cache. We will be interested in the partial
IDs, and only if they originate from explicit user information. Refactoring
makes logic and data accessible for reuse, and increases cohesion in general.
The docstring (and function name itself) described things as if IDs are
being assigned to the argnames, but actually they're assigned to the
parameter sets.
If we do the `update`s in the right order, we can avoid the `mark.name
not in self.keywords` check, since `self.keywords` starts out clean and
`update` will override previously set keywords.
By my analysis, this deleted code block has no effect:
1. `self.keywords` is `update`d with `callspec.marks`.
2. `self.own_markers` is `update`d with `callspec.marks`.
3. `self.keywords` is `update`d with `self.own_markers`.
So together steps 2+3 completely undo step 1.
This does have a slight semantic change: in a node hierarchy parent ->
child, if parent has a marker applied, then child is constructed, then
`parent.themarker = "overridden"`, previously
`child.keywords['themarker']` would return `True`, now it returns
`"overridden"`. But that's actually what I would have expected so I see
it as more of a bugfix.
(except `Instance`)
Currently, `Function` does this manually, but other node types don't get
their markers added to their `keywords`, but they should, if only for
consistency.
Marks are added to keywords in three places:
- `Node.add_marker`: name -> `Mark`
- `Function.__init__(callspec)`: name -> `Mark`
- `Function.__init__ iter_markers`: name -> True
I think it should be consistent, which will also help with some upcoming
code cleaning. The `Mark` seems more useful than just a `True`, so
switch to that.
