Determines a candidate simulator at runtime rather than hardcoding iPhone SE.
(cherry picked from commit 42b0b0667e)
Co-authored-by: Russell Keith-Magee <russell@keith-magee.com>
Two races related to the type lookup cache, when used in the
free-threaded build. This caused test_opcache to sometimes fail (as
well as other hard to re-produce failures).
When built on a MIPS architecture, `_MIPS_SIM` is used to determine
architecture specifics. The value is expected to match either
`_ABIO32`, `_ABIN32` or `_ABI64`.
In `gcc` config/mips/mips.h these values are defined as compiler
`builtin_define` inside of a switch/case. That means, mips64el and
mips64 architectures know about `_ABI64` but don't know about `_ABIO32`
and `_ABIN32`. In turn, when CPython tries to use them in comparison,
they may be undefined identifiers.
In default compiler behavior, the undefined identifier will be
evaluated as zero, and it will not match `_MIPS_SIM`. However, the
issues pop up when `-Wundef` (or, even worse, `-Werror=undef`) compiler
flag is enabled. Then suddenly it's visible as a warning or error.

Modifies the test helper that counts the list of open file descriptors to use
the optimised ``/dev/fd`` approach on all Apple platforms, not just macOS. This
avoids crashes caused by guarded file descriptors.

gh-131988: Fix a multithreaded scaling regression
The 3.13 free threaded build immortalizes certain objects to avoid
reference count contention. In gh-127114 the condition was
unintentionally changed to happen when the first thread was created
instead of the first non-main thread. The `interp->gc.immortalize` field
is then cleared again during `_PyGC_Init()`.
Change the condition so that we check if we should immortalize objects
using deferred reference counting whenever a non-main thread is created.

gh-129204: Add _PYTHON_SUBPROCESS_USE_POSIX_SPAWN environment knob (GH-132184)
* Add _PYTHON_SUBPROCESS_USE_POSIX_SPAWN environment knob
Add support for disabling the use of `posix_spawn` via a variable in
the process environment.
While it was previously possible to toggle this by modifying the value
of `subprocess._USE_POSIX_SPAWN`, this required either patching CPython
or modifying it within the interpreter instance which is not always
possible, such as when running applications or scripts not under a
user's control.
