* gh-127572: Fix `test_structmembers` initialization (GH-127577)Sam Gross2024-12-041-1/+1
| | | | | | | | gh-127572: Fix `test_structmembers` initialization. The 'C' format code expects an `int` as a destination (not a `char`). This led to test failures on big-endian platforms like s390x. Use the 'c' format code, which expects a `char` as the destination (but requires a Python byte objects instead of a str).

| | | | Don't make the assumption that the 'name' argument is a string. Use repr() to format the 'name' argument instead.
* gh-127330: Update for OpenSSL 3.4 & document+improve the update process ↵Petr Viktorin2024-11-284-4/+682
| | | | | | | | | | | | | | | | | (GH-127331) - Add `git describe` output to headers generated by `make_ssl_data.py` This info is more important than the date when the file was generated. It does mean that the tool now requires a Git checkout of OpenSSL, not for example a release tarball. - Regenerate the older file to add the info. To the other older file, add a note about manual edits. - Add notes on how to add a new OpenSSL version - Add 3.4 error messages and multissl tests
* gh-124008: Fix calculation of the number of written bytes for the Windows ↵Serhiy Storchaka2024-11-271-28/+90
| | | | | | | | | | | | console (GH-124059) Since MultiByteToWideChar()/WideCharToMultiByte() is not reversible if the data contains invalid UTF-8 sequences, use binary search to calculate the number of written bytes from the number of written characters. Also fix writing incomplete UTF-8 sequences. Also fix handling of memory allocation failures.
* gh-127072: Remove outdated `socket.NETLINK_*` constants. (GH-127256)RUANG (James Roy)2024-11-271-18/+2
| | | | | Remove seriously outdated netlink constants. Co-authored-by: Gregory P. Smith <greg@krypto.org>
* gh-69639: Add mixed-mode rules for complex arithmetic (C-like) (GH-124829)Sergey B Kirpichev2024-11-261-3/+47
| | | | | | | | | | | | | | | "Generally, mixed-mode arithmetic combining real and complex variables should be performed directly, not by first coercing the real to complex, lest the sign of zero be rendered uninformative; the same goes for combinations of pure imaginary quantities with complex variables." (c) Kahan, W: Branch cuts for complex elementary functions. This patch implements mixed-mode arithmetic rules, combining real and complex variables as specified by C standards since C99 (in particular, there is no special version for the true division with real lhs operand). Most C compilers implementing C99+ Annex G have only these special rules (without support for imaginary type, which is going to be deprecated in C2y).

| | | | | | | | | | startup failure (GH-109761) If Python fails to start newly created thread due to failure of underlying PyThread_start_new_thread() call, its state should be removed from interpreter' thread states list to avoid its double cleanup. Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* gh-127065: Make `methodcaller` thread-safe in free threading build (#127109)Sam Gross2024-11-221-0/+9
| | | | | | | The `methodcaller` C vectorcall implementation uses an arguments array that is shared across calls. The first argument is modified on every invocation. This isn't thread-safe in the free threading build. I think it's also not safe in general, but for now just disable it in the free threading build.
* gh-126316: Make grp.getgrall() thread-safe: add a mutex (#127055)Victor Stinner2024-11-212-22/+97
| | | | grpmodule.c is no longer built with the limited C API, since PyMutex is excluded from the limited C API.
* gh-126727: Fix locale.nl_langinfo(locale.ERA) (GH-126730)Serhiy Storchaka2024-11-211-24/+41
| | | | | It now returns multiple era description segments separated by semicolons. Previously it only returned the first segment on platforms with Glibc.
* gh-126991: Fix reference leak in loading pickle's opcode BUILD (GH-126990)Justin Applegate2024-11-191-0/+1
| | | If PyObject_SetItem() fails in the `load_build()` function of _pickle.c, no DECREF for the `dict` variable.

* gh-126554: ctypes: Correctly handle NULL dlsym values (GH-126555)George Alexopoulos2024-11-152-31/+95
| | | | | | | | | | | | | | | | | | | | | | | | | 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-126688: Reinit import lock after fork (#126692)Sam Gross2024-11-121-0/+1
| | | | | | 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().
* gh-76785: Improved Subinterpreters Compatibility with 3.12 (2/2) (gh-126707)Eric Snow2024-11-125-12/+46
