This makes mypy raise an error whenever it detects code which is
statically unreachable, e.g.
x: int
if isinstance(x, str):
... # Statement is unreachable [unreachable]
This is really neat and finds quite a few logic and typing bugs.
Sometimes the code is intentionally unreachable in terms of types, e.g.
raising TypeError when a function is given an argument with a wrong
type. In these cases a `type: ignore[unreachable]` is needed, but I
think it's a nice code hint.
This prevents referring to a generic type without filling in its generic
type parameters.
The FixtureDef typing might need some more refining in the future.
Also delay calling tearDown() when --pdb is given, so users still have
access to the instance variables (which are usually cleaned up during tearDown())
when debugging.
Fix#6947
Without this, the second time it tries to stop in a parametrized
function it raises instead:
`ValueError: --trace can't be used with a fixture named func!`

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.

This reverts commit e88aa957ae, reversing
changes made to 1410d3dc9a.
I do not think it warrants an option anymore, and there is a way to
achieve this via `--pdbcls` if needed.
While I think that pdb++ should be fixed in this regard (by using
`pdb.Pdb`, and not `self.__class__` maybe), this ensures that custom
debuggers like this are working.
Regarding tests: it merges ``test_pdb_interaction``,
``test_pdb_print_captured_stdout``, and
``test_pdb_print_captured_stderr`` into
``test_pdb_print_captured_stdout_and_stderr`` (clarity and performance,
especially since pexpect tests are slow).
This handles `header` similar to Python 3.7 does it, and forwards any
other keyword arguments to the Pdb constructor.
This allows for `__import__("pdb").set_trace(skip=["foo.*"])`.
Fixes https://github.com/pytest-dev/pytest/issues/4416.
This is relevant when using runpytest in-process.

After `pdb.set_trace()` capturing is turned off.
This patch resumes it after using the `continue` (or `c` / `cont`)
command.
Store _pytest_capman on the class, for pdbpp's do_debug hack to keep it.
Without this, `debug …` would fail like this:
/usr/lib/python3.6/cmd.py:217: in onecmd
return func(arg)
.venv/lib/python3.6/site-packages/pdb.py:608: in do_debug

- add pytest_leave_pdb hook
- fixes test_pdb_interaction_capturing_twice: would fail on master now,
but works here
