Change our mypy configuration to disallow untyped defs by default, which ensures *new* files added to the code base are fully typed.
To avoid having to type-annotate everything now, add `# mypy: allow-untyped-defs` to files which are not fully type annotated yet.
As we fully type annotate those modules, we can then just remove that directive from the top.
This has been there since as far as the git history goes (2007), is not
covered by any test, and says "Buggy python version consider upgrading".
Hopefully everyone have upgraded...
Everything was using `_pytest.compat.getfslineno` basically, which
wrapped `_pytest._code.source.getfslineno`.
This moves the extra code from there into it directly, and uses the
latter everywhere.
This helps to eventually remove the one in compat eventually, and also
causes less cyclic imports.
These are more "dirty" than the previous batch (that's why they were
left out). The trouble is that `compile` can return either a code object
or an AST depending on a flag, so we need to add an overload to make the
common case Union free. But it's still worthwhile.
This fixes some type: ignores due to typeshed update.
Newer mypy seem to ignore unannotated functions better, so add a few
minor annotations so that existing correct type:ignores make sense.
Source was previously iterable because it implements `__getitem__()`,
which is apparently a thing from before `__iter__()` was introduced.
To reduce mypy's and my own confusion, implement `__iter__()` directly.
Add some Python 3.8 type: ignores; all are already fixed in the next
mypy release, so can be removed once we upgrade.
Also move some flake8 ignores which seem to have changed places.
Add a very lax mypy configuration, add it to tox -e linting, and
fix/ignore the few errors that come up. The idea is to get it running
before diving in too much.
This enables:
- Progressively adding type annotations and enabling more strict
options, which will improve the codebase (IMO).
- Annotating the public API in-line, and eventually exposing it to
library users who use type checkers (with a py.typed file).
Though, none of this is done yet.
