This update for python313 fixes the following issues: Update to version 3.13.7. - Fixes in 3.13.7: * gh-137583: Fix a deadlock introduced in 3.13.6 when a call to ssl.SSLSocket.recv was blocked in one thread, and then another method on the object (such as ssl.SSLSocket.send) was subsequently called in another thread. * gh-137044: Return large limit values as positive integers instead of negative integers in resource.getrlimit(). Accept large values and reject negative values (except RLIM_INFINITY) for limits in resource.setrlimit(). * gh-136914: Fix retrieval of doctest.DocTest.lineno for objects decorated with functools.cache() or functools.cached_property. * gh-131788: Make ResourceTracker.send from multiprocessing re-entrant safe * gh-136155: We are now checking for fatal errors in EPUB builds in CI. * gh-137400: Fix a crash in the free threading build when disabling profiling or tracing across all threads with PyEval_SetProfileAllThreads() or PyEval_SetTraceAllThreads() or their Python equivalents threading.settrace_all_threads() and threading.setprofile_all_threads(). - Fixes in 3.13.6: * Security - gh-135661: Fix parsing start and end tags in html.parser.HTMLParser according to the HTML5 standard. - Whitespaces no longer accepted between </ and the tag name. E.g. </ script> does not end the script section. - Vertical tabulation (\v) and non-ASCII whitespaces no longer recognized as whitespaces. The only whitespaces are \t\n\r\f and space. - Null character (U+0000) no longer ends the tag name. - Attributes and slashes after the tag name in end tags are now ignored, instead of terminating after the first > in quoted attribute value. E.g. </script/foo='>'/>. - Multiple slashes and whitespaces between the last attribute and closing > are now ignored in both start and end tags. E.g. <a foo=bar/ //>. - Multiple = between attribute name and value are no longer collapsed. E.g. <a foo==bar> produces attribute “foo” with value “=bar”. - gh-102555: Fix comment parsing in html.parser.HTMLParser according to the HTML5 standard. --!> now ends the comment. -- > no longer ends the comment. Support abnormally ended empty comments <--> and <--->. - gh-135462: Fix quadratic complexity in processing specially crafted input in html.parser.HTMLParser. End-of-file errors are now handled according to the HTML5 specs – comments and declarations are automatically closed, tags are ignored (CVE-2025-6069, bsc#1244705). - gh-118350: Fix support of escapable raw text mode (elements “textarea” and “title”) in html.parser.HTMLParser. * Core and Builtins - gh-58124: Fix name of the Python encoding in Unicode errors of the code page codec: use “cp65000” and “cp65001” instead of “CP_UTF7” and “CP_UTF8” which are not valid Python code names. Patch by Victor Stinner. - gh-137314: Fixed a regression where raw f-strings incorrectly interpreted escape sequences in format specifications. Raw f-strings now properly preserve literal backslashes in format specs, matching the behavior from Python 3.11. For example, rf'{obj:\xFF}' now correctly produces '\\xFF' instead of 'ÿ'. Patch by Pablo Galindo. - gh-136541: Fix some issues with the perf trampolines on x86-64 and aarch64. The trampolines were not being generated correctly for some cases, which could lead to the perf integration not working correctly. Patch by Pablo Galindo. - gh-109700: Fix memory error handling in PyDict_SetDefault(). - gh-78465: Fix error message for cls.__new__(cls, ...) where cls is not instantiable builtin or extension type (with tp_new set to NULL). - gh-135871: Non-blocking mutex lock attempts now return immediately when the lock is busy instead of briefly spinning in the free threading build. - gh-135607: Fix potential weakref races in an object’s destructor on the free threaded build. - gh-135496: Fix typo in the f-string conversion type error (“exclamanation” -> “exclamation”). - gh-130077: Properly raise custom syntax errors when incorrect syntax containing names that are prefixes of soft keywords is encountered. Patch by Pablo Galindo. - gh-135148: Fixed a bug where f-string debug expressions (using =) would incorrectly strip out parts of strings containing escaped quotes and # characters. Patch by Pablo Galindo. - gh-133136: Limit excess memory usage in the free threading build when a large dictionary or list is resized and accessed by multiple threads. - gh-132617: Fix dict.update() modification check that could incorrectly raise a “dict mutated during update” error when a different dictionary was modified that happens to share the same underlying keys object. - gh-91153: Fix a crash when a bytearray is concurrently mutated during item assignment. - gh-127971: Fix off-by-one read beyond the end of a string in string search. - gh-125723: Fix crash with gi_frame.f_locals when generator frames outlive their generator. Patch by Mikhail Efimov. * Library - gh-132710: If possible, ensure that uuid.getnode() returns the same result even across different processes. Previously, the result was constant only within the same process. Patch by Bénédikt Tran. - gh-137273: Fix debug assertion failure in locale.setlocale() on Windows. - gh-137257: Bump the version of pip bundled in ensurepip to version 25.2 - gh-81325: tarfile.TarFile now accepts a path-like when working on a tar archive. (Contributed by Alexander Enrique Urieles Nieto in gh-81325.) - gh-130522: Fix unraisable TypeError raised during interpreter shutdown in the threading module. - gh-130577: tarfile now validates archives to ensure member offsets are non-negative. (Contributed by Alexander Enrique Urieles Nieto in gh-130577; CVE-2025-8194, bsc#1247249). - gh-136549: Fix signature of threading.excepthook(). - gh-136523: Fix wave.Wave_write emitting an unraisable when open raises. - gh-52876: Add missing keepends (default True) parameter to codecs.StreamReaderWriter.readline() and codecs.StreamReaderWriter.readlines(). - gh-85702: If zoneinfo._common.load_tzdata is given a package without a resource a zoneinfo.ZoneInfoNotFoundError is raised rather than a PermissionError. Patch by Victor Stinner. - gh-134759: Fix UnboundLocalError in email.message.Message.get_payload() when the payload to decode is a bytes object. Patch by Kliment Lamonov. - gh-136028: Fix parsing month names containing “İ” (U+0130, LATIN CAPITAL LETTER I WITH DOT ABOVE) in time.strptime(). This affects locales az_AZ, ber_DZ, ber_MA and crh_UA. - gh-135995: In the palmos encoding, make byte 0x9b decode to › (U+203A - SINGLE RIGHT-POINTING ANGLE QUOTATION MARK). - gh-53203: Fix time.strptime() for %c and %x formats on locales byn_ER, wal_ET and lzh_TW, and for %X format on locales ar_SA, bg_BG and lzh_TW. - gh-91555: An earlier change, which was introduced in 3.13.4, has been reverted. It disabled logging for a logger during handling of log messages for that logger. Since the reversion, the behaviour should be as it was before 3.13.4. - gh-135878: Fixes a crash of types.SimpleNamespace on free threading builds, when several threads were calling its __repr__() method at the same time. - gh-135836: Fix IndexError in asyncio.loop.create_connection() that could occur when non-OSError exception is raised during connection
