With macOS framework builds, test case test_nonexisting_script in
test_nonexisting_script fails because the test case assumes that
the file name in sys.executable will appear in the error message.
For macOS framework builds, sys.executable is the file name of the
stub launcher and its file name bears no relationship to the file
name of the actual python executable.  For now, skip the test in
this case.

Replace "Availability: xxx" with ".. availability:: xxx" in the doc.

for the SHAKE algorithm in the hashlib module.

It was proposed to add an warning for http.server regarding security
issues. The wording was provided at bpo-26005 by @orsenthil

Unconditional forcing of ``CHECKED_HASH`` invalidation was introduced in
3.7.0 in bpo-29708.  The change is bad, as it unconditionally overrides
*invalidation_mode*, even if it was passed as an explicit argument to
``py_compile.compile()`` or ``compileall``.  An environment variable
should *never* override an explicit argument to a library function.
That change leads to multiple test failures if the ``SOURCE_DATE_EPOCH``
environment variable is set.

This changes ``py_compile.compile()`` to only look at
``SOURCE_DATE_EPOCH`` if no explicit *invalidation_mode* was specified.
I also made various relevant tests run with explicit control over the
value of ``SOURCE_DATE_EPOCH``.

While looking at this, I noticed that ``zipimport`` does not work
with hash-based .pycs _at all_, though I left the fixes for
subsequent commits.

:meth:`mimetypes.MimeTypes.guess_type` now accepts :term:`path-like object` in addition to url strings.

Tests involving sending signals to the semaphore_tracker will not fail anymore due to
the fact that running the test suite with -Werror propagates warnings as errors.

Fix a missing assertion when the semaphore_tracker is expected to die.

Add unit tests for the command line for the gzip module

When Python is built with the intel control-flow protection flags,
-mcet -fcf-protection, gdb is not able to read the stack without
actually jumping inside the function. This means an extra
'next' command is required to make the $pc (program counter)
enter the function and make the stack of the function exposed to gdb.
