gh-136057: Allow step and next to step over for loops (GH-136160)
(cherry picked from commit 8be3b2f479)
Co-authored-by: Tian Gao <gaogaotiantian@hotmail.com>
This splits the OS API specific functionality to get the number of threads out
from the fallback Python method and warning raising code itself. This way the
OS APIs can be queried before we've run
`os.register_at_fork(after_in_parent=...)` registered functions which
themselves may (re)start threads that would otherwise be detected.
This is best effort. If the OS APIs are either unavailable or fail, the
warning generating code still falls back to looking at the Python threading
state after the CPython interpreter world has been restarted and the
after_in_parent calls have been made. The common case for most Linux and macOS
environments should work today.
This also lines up with the existing TODO refactoring, we may choose to expose
this API to get the number of OS threads in the `os` module in the future.
Note: This is a simplified backport that maintains the void return type
for warn_about_fork_with_threads() and keeps PyErr_Clear() in the warning path,
as the error handling changes from fd8f42d3d1 are not needed in 3.14.
This fixes an assertion error when the new computed start is not an integer.

gh-140815: Fix faulthandler for invalid/freed frame (GH-140921)
faulthandler now detects if a frame or a code object is invalid or

* _PyFrame_SafeGetCode()
* _PyFrame_SafeGetLasti()
_PyMem_IsPtrFreed() now detects pointers in [-0xff, 0xff] range
as freed.

* [3.14] gh-90949: add Expat API to prevent XML deadly allocations (CVE-2025-59375) (GH-139234)
Expose the XML Expat 2.7.2 mitigation APIs to disallow use of
disproportional amounts of dynamic memory from within an Expat
parser (see CVE-2025-59375 for instance).
The exposed APIs are available on Expat parsers, that is,
parsers created by `xml.parsers.expat.ParserCreate()`, as:
- `parser.SetAllocTrackerActivationThreshold(threshold)`, and
- `parser.SetAllocTrackerMaximumAmplification(max_factor)`.
