Alex Willmer 123efa7510 mitogen: Support Python 3.12
Most of the necessary changes were made in recent PEP 451 commits. This bumps
the CI jobs, and declares the support. Test dependendancies are bumped to
latest supportted/available versions.

Alex Willmer 5ad3d14ceb mitogen: Support PEP 451 ModuleSpec API, required for Python 3.12
importlib.machinery.ModuleSpec and find_spec() were introduced in Python 3.4
under PEP 451. They replace the find_module() API of PEP 302, which was
deprecated from Python 3.4. They were removed in Python 3.12 along with the
imp module.

This change adds support for the PEP 451 APIs. Mitogen should no longer import
imp on Python versions that support ModuleSpec. Tests have been added to cover
the new APIs.

CI jobs have been added to cover Python 3.x on macOS.

Alex Willmer 3a31a7d886 mitogen: Workaround CPython importlib PermissionError when cwd is unreadable
On macOS when using a become plugin as an unprivileged user, to another
unprivileged user it is likely that the current working directory can't be
read. In this case os.cwd() raises PermissionError.

On versions of Python currently in the wild (March 2024, CPython <= 3.13) if
any non-builtin or non-frozen module (e.g. zlib, base64) is imported then
`importlib._bootstrap_external.PathFinder._path_importer_cache()` attempts to
call os.cwd() without catching PermissionError.

The previous comment about needing an extra .encode() appears to be wrong,
atleast for Python 3.x >= 3.6.

Command size increased by 54 bytes, bootstrap by 804 bytes. Changed from
codecs module to binascii & zlib because they're extensions, and importing
them triggers fewer supporting imports (e.g. encodings module).

Alex Willmer 21cb4a3472 CI: Remove faulthandler fallback requirement
faulthandler is a stdlib module in Python 3.3+. For a long time a PyPI package
of the same name was available for earlier Python releases. That package has
since been removed from PyPI, and the source respoitory archived. So we should
not rely on it.

Alex Willmer 0af2ce8c30 Remove ansible_mitogen Connection.close() workaround
Refs #925 #969

I'm not 100% confident that merely removing this is the full fix,
without substituting something else. I am sure keeping it would be
the greater of two evils. __del__() should be avoided on general
principal, and it's associated with multiple intermittant CI
failures, plus multiple user reported issues.

Alex Willmer 25ea6dde02 ansible_mitogen: Allow mitogen_fetch to bypass slurp module
This reapplies an earlier change, when this plugin was first introduced to
Mitogen. The plugin was updated to fix

[DEPRECATION WARNING]: The '_remote_checksum()' method is deprecated.

I've elected to short-circuit the if statemtn logic, rather than
deleting/unindenting, to make the code delta much smaller. This should make it
easier to maintain/update.

Alex Willmer d2ca8a9423 master.ParentEnumerationMethod: Require matching pkg.__name__
Co-authored-by: Stefano Rivera <stefano@rivera.za.net>

When the requested module (e.g. ansible.module_utils.distro)
- is provided by another module *e.g. distro)
- that itself was a package (e.g. distro 1.7.0)

At runtime
- ansible/module_utils/distro/__init__.py executes
- if https://pypi.org/project/distro/ is present, it's loaded as
ansible.module_utils.distro
- otherwise ansible/module_utils/distro/_distro.py is loaded

ParentEnumerationMethod would wrongly use whatever was in
sys.modules['ansible.module_utils.distro]. Instead we should ascend to
the first parent that has fullname == sys.modules[fullname].__name__.
Then descend to the appropriate .py file on disk.

This bug didn't show up before because until distro 1.7.0 (Feb 2022) the
top-level distro module was a module (distro.py) not a package
(distro/__init__.py)

Alex Willmer a990eb3d77 CI: Remove obsolete reverse shell historically used to debug CI
This reverse shell was historically used to debug CI jobs interactively.
It is not used anymore, and may be causing jobs to hang, then timeout.
There is no reason to keep it, and removing it simplifies CI jobs.

Additionally it has been reported as flagged by security scanners, so
removing it makes Mitogen easier to package/adopt.

Alex Willmer bce3bab3e8 Add the msvcrt moduleto the default module deny list
Commit https://github.com/python/cpython/commit/880d42a3b247 (first
released in Python 3.8a0) moved an import of msvcrt from an if <win32>
block, into a try/except block. So now the import is tried even on Linux
or MacOS.

https://docs.python.org/3/library/msvcrt.html is a Windows specific
builtin.

Alex Willmer 1e72ebaf8b tests: Update test coverage to Python 3.9
The Travis Linux distribution must be upgraded because the Trusty
(Ubuntu 14.04) image does not have Python 3.9. Xenial (Ubuntu 16.04) is
the earliest version that offers Python 3.9.

I have not chosen a later release, in order to aid restoration of Python
2.4 - 2.6 tests.
