* gh-126554: ctypes: Correctly handle NULL dlsym values (GH-126555)George Alexopoulos2024-11-154-31/+220
| | | | | | | | | | | | | | | | | | | | | | | | | For dlsym(), a return value of NULL does not necessarily indicate an error [1]. Therefore, to avoid using stale (or NULL) dlerror() values, we must: 1. clear the previous error state by calling dlerror() 2. call dlsym() 3. call dlerror() If the return value of dlerror() is not NULL, an error occured. In ctypes we choose to treat a NULL return value from dlsym() as a "not found" error. This is the same as the fallback message we use on Windows, Cygwin or when getting/formatting the error reason fails.

* gh-126807: pygettext: Do not attempt to extract messages from function ↵Tomas R.2024-11-143-5/+36
| | | | | | | | | | | | | | | | definitions. (GH-126808) Fixes a bug where pygettext would attempt to extract a message from a code like this: def _(x): pass This is because pygettext only looks at one token at a time and '_(x)' looks like a function call. However, since 'x' is not a string literal, it would erroneously issue a warning.
* GH-126766: `url2pathname()`: handle empty authority section. (#126767)Barney Gale2024-11-144-9/+14
| | | | | Discard two leading slashes from the beginning of a `file:` URI if they introduce an empty authority section. As a result, file URIs like `///etc/hosts` are correctly parsed as `/etc/hosts`.

* gh-123832: Adjust `socket.getaddrinfo` docs for better POSIX compliance ↵Petr Viktorin2024-11-141-3/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (GH-126182) * gh-123832: Adjust `socket.getaddrinfo` docs for better POSIX compliance This changes nothing changes for CPython supported platforms, but hints how to deal with platforms that stick to the letter of the spec. It also marks `socket.getaddrinfo` as a wrapper around `getaddrinfo(3)`; specifically, workarounds to make the function work consistently across platforms are out of scope in its code. Include wording similar to the POSIX's “by providing options and by limiting the returned information”, which IMO suggests that the hints limit the resulting list compared to the defaults, *but* can be interpreted differently. Details are added in a note. Specifically say that this wraps the underlying C function. So, the details are in OS docs. The “full range of results” bit goes away. Use `AF_UNSPEC` rather than zero for the *family* default, although I don't think a system where it's nonzero would be very usable. Suggest setting proto and/or type (with examples, as the appropriate values aren't obvious). Say why you probably want to do that that on all systems; mention the behavior on the “letter of the spec” systems. Suggest that the results should be tried in order, which is, AFAIK best practice -- see RFC 6724 section 2, and its predecessor from 2003 (which are specific to IP, but indicate how people use this): > Well-behaved applications SHOULD iterate through the list of > addresses returned from `getaddrinfo()` until they find a working address.

* Doc: Recommend shlex.quote alongside pipes removal (#126570)Colin Watson2024-11-141-0/+2
| | | | | | | One of the most common reasons I see the old `pipes` module still in use when porting to Python 3.13 is for the undocumented `pipes.quote` function, which can easily be replaced with `shlex.quote`. I think it's worth specifically calling this out, since being directed to the `subprocess` module would be confusing in this case.

* GH-118289: Fix handling of non-directories in `posixpath.realpath()` (#120127)Barney Gale2024-11-133-4/+75
| | | | | | | In strict mode, raise `NotADirectoryError` if we encounter a non-directory while we still have path parts left to process. We use a `part_count` variable rather than `len(rest)` because the `rest` stack also contains markers for unresolved symlinks.

* gh-71936: Fix race condition in multiprocessing.Pool (GH-124973)Petr Viktorin2024-11-133-13/+22
| | | | | | | | | | | | | | | | | | * gh-71936: Fix race condition in multiprocessing.Pool Proxes of shared objects register a Finalizer in BaseProxy._incref(), and it will call BaseProxy._decref() when it is GCed. This may cause a race condition with Pool(maxtasksperchild=None) on Windows. A connection would be closed and raised TypeError when a GC occurs between _ConnectionBase._check_writable() and _ConnectionBase._send_bytes() in _ConnectionBase.send() in the second or later task, and a new object is allocated that shares the id() of a previously deleted one. Instead of using the id() of the token (or the proxy), use a unique, non-reusable number. Co-Authored-By: Akinori Hattori <hattya@gmail.com>
* gh-104745: Limit starting a patcher more than once without stopping it (#126649)Red4Ru2024-11-133-2/+62
| | | | | | | | Previously, this would cause an `AttributeError` if the patch stopped more than once after this, and would also disrupt the original patched object. --------- Co-authored-by: Peter Bierma <zintensitydev@gmail.com> Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com>

| | | | | | The PyMutex implementation supports unlocking after fork because we clear the list of waiters in parking_lot.c. This doesn't work as well for _PyRecursiveMutex because on some systems, such as SerenityOS, the thread id is not preserved across fork().
