Sam Gross	11a8652e25	gh-137185: Fix _Py_DumpStack() async signal safety (gh-137187) ... Call backtrace() once when installing the signal handler to ensure that libgcc is dynamically loaded outside the signal handler. This fixes a "signal-unsafe call inside of a signal" TSan error from test_faulthandler.test_enable_fd.	2025-07-29 14:25:32 +00:00

Ron Frederick	377b787618	gh-136306: Add support for getting and setting SSL groups (#136307) ... Add support for getting and setting groups used for key agreement. * `ssl.SSLSocket.group()` returns the name of the group used for the key agreement of the current session establishment. This feature requires Python to be built with OpenSSL 3.2 or later. * `ssl.SSLContext.get_groups()` returns the list of names of groups that are compatible with the TLS version of the current context. This feature requires Python to be built with OpenSSL 3.5 or later. * `ssl.SSLContext.set_groups()` sets the groups allowed for key agreement for sockets created with this context. This feature is always supported.	2025-07-28 19:33:31 +02:00

Bénédikt Tran	45138d3584	gh-131876: extract _hashlib helpers into a separate directory (#136995) ... The `Modules/hashlib.h` helper file is now removed and split into multiple files: * `Modules/_hashlib/hashlib_buffer.[ch]` -- Utilities for getting a buffer view and handling buffer inputs. * `Modules/_hashlib/hashlib_fetch.h` -- Utilities used when fetching a message digest from a digest-like identifier. Currently, this file only contains common error messages as the fetching API is not yet implemented. * `Modules/_hashlib/hashlib_mutex.h` -- Utilities for managing the lock on cryptographic hash objects.	2025-07-28 11:28:48 +02:00
Bénédikt Tran	eefd70f0ed	gh-136968: fortify macro usage in cryptographic modules (#136973) ... Macros used in cryptographic extension modules are partially rewritten to use `static inline` functions when possible to help code completion.	2025-07-28 07:36:15 +00:00
Duprat	4e40f2bea7	gh-132898: Add a note in multiprocessing.Process docs about creating a process in a REPL (GH-137118) ... * Reword, expand, and clarify the limitation, highlighting the REPL case. * Mention in the high level Process description. * added a pointer to the GH issue from the doc note --------- Co-authored-by: Gregory P.

Toshaksha	6784ef7da7	gh-136278: Document codecs.escape_encode() and codecs.escape_decode() (#136314) ... Closes #136278	2025-07-27 16:37:52 +00:00
Barney Gale	2bd4ff0700	GH-128520: pathlib ABCs: tweak protocol for virtual path strings (#134104) ... Adjust `pathlib._os.vfspath()` so that it doesn't try `os.fsdecode()`. I don't know that supporting `os.PathLike` arguments is a good idea, so it's best to leave it out for now.	2025-07-27 12:47:15 +01:00
Barney Gale	10a925c86d	GH-137059: url2pathname(): fix support for drive letter in netloc (#137060) ... Support file URLs like `file://c:/foo` in `urllib.request.url2pathname()` on Windows. This restores behaviour from 3.13.	2025-07-27 11:44:41 +00:00
Iqra Khan	ae8b7d7100	gh-136992: Add "None" as valid SameSite value as per RFC 6265bis (#137040) ... The "SameSite" attribute defined in RFC 6265bis [1] allows the "Strict", "Lax" and "None" enforcement modes. We already documented "Strict" and "Lax" as being valid values but "None" was missing from the list. While the RFC has not been formally approved, modern browsers support the "None" value [2, 3] thereby making sense to document it. [1]: https://datatracker.ietf.org/doc/html/draft-ietf-httpbis-rfc6265bis [2]: https://developers.google.com/search/blog/2020/01/get-ready-for-new-samesitenone-secure [3]: https://developer.mozilla.org/en-US/docs/Web/HTTP/Reference/Headers/Set-Cookie#none --------- Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com>	2025-07-27 10:27:08 +02:00
Abdul	cfd6da849a	gh-137058: Update C23 standard version check in pyport.h (#137127) ... Use `__STDC_VERSION__ >= 202311L` instead of `__STDC_VERSION__ > 201710L`.	2025-07-27 09:47:21 +02:00

Stephen Morton	d5fa437dfb	gh-126662: naming consistency for signal.ItimerError (#126712)	2025-07-26 22:14:12 +05:30
Bénédikt Tran	d658b9053b	gh-136912: fix handling of OverflowError in hmac.digest (#136917) ... The OpenSSL and HACL* implementations of HMAC single-shot digest computation reject keys whose length exceeds `INT_MAX` and `UINT32_MAX` respectively. The OpenSSL implementation also rejects messages whose length exceed `INT_MAX`. Using such keys in `hmac.digest` previously raised an `OverflowError` which was propagated to the caller. This commit mitigates this case by making `hmac.digest` fall back to HMAC's pure Python implementation which accepts arbitrary large keys or messages. This change only affects the top-level entrypoint `hmac.digest`, leaving `_hashopenssl.hmac_digest` and `_hmac.compute_digest` untouched.	2025-07-26 08:22:06 +00:00
Savannah Bailey	f7c380ef67	GH-132732: Use pure op machinery to optimize COMPARE_OP_INT/FLOAT/STR (#137062) ... Co-authored-by: Ken Jin <kenjin4096@gmail.com>	2025-07-25 19:02:04 -07:00

Bénédikt Tran	7ce2f101c4	gh-136929: ensure that hashlib.<name> does not raise AttributeError (#136933) ... Previously, if OpenSSL was not present and built-in cryptographic extension modules were disabled, requesting `hashlib.<name>` raised `AttributeError` and an ERROR log message with the exception traceback is emitted when importing `hashlib`. Now, the named constructor function will always be available but raises a `ValueError` at runtime indicating that the algorithm is not supported. The log message has also been reworded to be less verbose.	2025-07-25 14:49:09 +00:00
Raymond Hettinger	ea06ae5b5e	Fix Queue.shutdown docs for condition to unblock a join (gh-137088)	2025-07-25 07:56:28 -06:00

Peter Bierma	9b451fb457	gh-137093: Fix race condition in test_embed.test_bpo20891 (GH-137094) ... Use a `PyEvent` instead of a lock to fix a race on the free-threaded build.	2025-07-25 08:33:18 -04:00
Denis Laxalde	fece15d29f	gh-136914: Fix support of cached functions and properties in DocTest's lineno computation (GH-136930) ... Previously, DocTest's lineno of functions and methods decorated with functools.cache(), functools.lru_cache() and functools.cached_property() was not properly returned (None was returned) because the computation relied on inspect.isfunction() which does not consider the decorated result as a function. We now use the more generic inspect.isroutine(), as elsewhere in doctest's logic. Also, added a special case for functools.cached_property().	2025-07-25 12:46:12 +03:00
Zachary Ware	d5e75c0768	Exclude _testclinic_depr.c.h from c-analyzer (GH-137086) ... _testclinic.c mocks out PY_VERSION_HEX to 3.8 before including _testclinic_depr.c.h to avoid the errors the preprocessor would otherwise throw due to the deprecation feature it is testing. Also partially revert 74e2acddf6: this restores Modules/_testclinic.c to match the same file in the 3.14 branch.	2025-07-24 15:50:01 -05:00
Kumar Aditya	9a6b60af40	gh-136870: fix data races in instrumentation of bytecode (#136994) ... De-instrumenting code objects modifies the thread local bytecode for all threads as such, holding the critical section on the code object is not sufficient and leads to data races. Now, the de-instrumentation is now performed under a stop the world pause as such no thread races with executing the thread local bytecode while it is being de-instrumented.	2025-07-24 17:58:46 +00:00

Brett Cannon	ec7fad79d2	Touch up Setup.local handling in Tools/wasm/wasi (GH-137051) ... The comment in the generated file is now more self-explanatory. The checks for unexpected file contents are also strengthened.	2025-07-23 11:50:15 -07:00
