The "pyperf command" tool be used instead. Example:
$ python3 -m pyperf command -- python3 -c pass
.....................
command: Mean +- std dev: 17.8 ms +- 0.4 ms
pyperf also computes the standard deviation which gives an idea of
the benchmark looks reliable or not.
Signal wakeup fd errors are now logged with
_PyErr_WriteUnraisableMsg(), rather than PySys_WriteStderr() and
PyErr_WriteUnraisable(), to pass the error message to
sys.unraisablehook. By default, it's still written into stderr (unless
sys.unraisablehook is overriden).
test_tools.test_sundry() now uses an unittest mock to prevent the
logging module to register a real "atfork" function which kept the
logging module dictionary alive. So the logging module can be
properly unloaded. Previously, the logging module was loaded before
test_sundry(), but it's no longer the case since recent test_tools
sub-tests removals.
The `}` marked with `/* End instructions */` is the end of the switch.
There is another pair of `{}` around the switch, which is vestigial
from ancient times when it was `for (;;) { switch (opcode) { ... } }`.
All `DISPATCH` macro calls should be inside that pair.
asciilib_count() is the same than ucs1lib_count(): the code is not
specialized for ASCII strings, so it's not worth it to have a
separated function. Remove asciilib_count() function.
Remove outdated example scripts of the Tools/scripts/ directory:
* gprof2html.py
* md5sum.py
* nm2def.py
* pathfix.py
* win_add2path.py
Remove test_gprof2html, test_md5sum and test_pathfix of test_tools.
This seems pretty straightforward. The issue mentions other calls in mmapmodule that we could release the GIL on, but those are in methods where we'd need to be careful to ensure that something sensible happens if those are called concurrently. In prior art, note that #12073 released the GIL for munmap. In a toy benchmark, I see the speedup you'd expect from doing this.

* gh-96821: Fix undefined behaviour in `audioop.c`
Left-shifting negative numbers is undefined behaviour.
Fortunately, multiplication works just as well, is defined behaviour,
and gets compiled to the same machine code as before by optimizing
compilers.

The definition of obj in the `Py_buffer` struct is as a PyObject*
ec091bd47e/Include/pybuffer.h (L22)
PyMemoryView_GET_BASE returns `.obj` - thus its return type
should be a PyObject* (or at least a void*). It definitely
doesn't return `Py_buffer`

There is no reason for this watcher to be attached to any particular loop.
This should make it safe to use regardless of the lifetime of the event loop running in the main thread
(relative to other loops).

The test failed on a buildbot because the pointer was only 7 hex characters. To be safe,
I bumped it down to 3: 4 in case we have 32-bit platforms, and 3 in case the pointer is very small.
