Matěj Cepl f41d0d940b Update to 3.14.3 ...

- Tools/Demos
    - gh-142095: Make gdb ‘py-bt’ command use frame from thread
      local state when available. Patch by Sam Gross and Victor
      Stinner.
  - Tests
    - gh-144415: The Android testbed now distinguishes between
      stdout/stderr messages which were triggered by a newline,
      and those triggered by a manual call to flush. This fixes
      logging of progress indicators and similar content.
    - gh-143460: Skip tests relying on infinite recusion if stack
      size is unlimited.
    - gh-65784: Add support for parametrized resource wantobjects
      in regrtests, which allows to run Tkinter tests with the
      specified value of tkinter.wantobjects, for example -u
      wantobjects=0.
    - gh-143553: Add support for parametrized resources, such as
      -u xpickle=2.7.
    - gh-142836: Accommodated Solaris in
      test_pdb.test_script_target_anonymous_pipe.
    - bpo-31391: Forward-port test_xpickle from Python 2 to
      Python 3 and add the resource back to test’s command line.
  - Security
    - gh-144125: BytesGenerator will now refuse to serialize
      (write) headers that are unsafely folded or delimited; see
      verify_generated_headers. (Contributed by Bas Bloemsaat and
      Petr Viktorin in gh-121650).
    - gh-143935: Fixed a bug in the folding of comments when
      flattening an email message using a modern email policy.
      Comments consisting of a very long sequence of non-foldable
      characters could trigger a forced line wrap that omitted
      the required leading space on the continuation line,
      causing the remainder of the comment to be interpreted as
      a new header field. This enabled header injection with
      carefully crafted inputs (bsc#1257029, CVE-2025-11468).
    - gh-143925: Reject control characters in data: URL media
      types.
    - gh-143919: Reject control characters in http.cookies.Morsel
      fields and values (bsc#1257031, CVE-2026-0672).
    - gh-143916: Reject C0 control characters within
      wsgiref.headers.Headers fields, values, and parameters.
  - Library
    - gh-144380: Improve performance of io.BufferedReader line
      iteration by ~49%.
    - gh-144169: Fix three crashes when non-string keyword
      arguments are supplied to objects in the ast module.
    - gh-144100: Fixed a crash in ctypes when using a deprecated
      POINTER(str) type in argtypes. Instead of aborting, ctypes
      now raises a proper Python exception when the pointer
      target type is unresolved.
    - gh-144050: Fix stat.filemode() in the pure-Python
      implementation to avoid misclassifying invalid mode values
      as block devices.
    - gh-144023: Fixed validation of file descriptor 0 in posix
      functions when used with follow_symlinks parameter.
    - gh-143999: Fix an issue where inspect.getgeneratorstate()
      and inspect.getcoroutinestate() could fail for generators
      wrapped by types.coroutine() in the suspended state.
    - gh-143831: annotationlib.ForwardRef objects are now
      hashable when created from annotation scopes with closures.
      Previously, hashing such objects would throw an exception.
      Patch by Bartosz Sławecki.
    - gh-143874: Fixed a bug in pdb where expression results were
      not sent back to remote client.
    - gh-143880: Fix data race in functools.partial() in the free
      threading build.
    - gh-143706: Fix multiprocessing forkserver so that sys.argv
      is correctly set before __main__ is preloaded. Previously,
      sys.argv was empty during main module import in forkserver
      child processes. This fixes a regression introduced in
      3.13.8 and 3.14.1. Root caused by Aaron Wieczorek, test
      provided by Thomas Watson, thanks!
    - gh-143638: Forbid reentrant calls of the pickle.Pickler and
      pickle.Unpickler methods for the C implementation.
      Previously, this could cause crash or data corruption, now
      concurrent calls of methods of the same object raise
      RuntimeError.
    - gh-78724: Raise RuntimeError’s when user attempts to call
      methods on half-initialized Struct objects, For example,
      created by Struct.__new__(Struct). Patch by Sergey
      B Kirpichev.
    - gh-143196: Fix crash when the internal encoder object
      returned by undocumented function
      json.encoder.c_make_encoder() was called with non-zero
      second (_current_indent_level) argument.
    - gh-143191: _thread.stack_size() now raises ValueError if
      the stack size is too small. Patch by Victor Stinner.
    - gh-143602: Fix a inconsistency issue in write() that leads
      to unexpected buffer overwrite by deduplicating the buffer
      exports.
    - gh-143547: Fix sys.unraisablehook() when the hook raises an
      exception and changes sys.unraisablehook(): hold a strong
      reference to the old hook. Patch by Victor Stinner.
    - gh-143517: annotationlib.get_annotations() no longer raises
      a SyntaxError when evaluating a stringified starred
      annotation that starts with one or more whitespace
      characters followed by a *. Patch by Bartosz Sławecki.
    - gh-143378: Fix use-after-free crashes when a BytesIO object
      is concurrently mutated during write() or writelines().
    - gh-143346: Fix incorrect wrapping of the Base64 data in
      plistlib._PlistWriter when the indent contains a mix of
      tabs and spaces.
    - gh-143310: tkinter: fix a crash when a Python list is
      mutated during the conversion to a Tcl object (e.g., when
      setting a Tcl variable). Patch by Bénédikt Tran.
    - gh-143309: Fix a crash in os.execve() on non-Windows
      platforms when given a custom environment mapping which is
      then mutated during parsing. Patch by Bénédikt Tran.
    - gh-143308: pickle: fix use-after-free crashes when
      a PickleBuffer is concurrently mutated by a custom buffer

      Patch by Fatih Celik.
    - gh-142830: sqlite3: fix use-after-free crashes when the
      connection’s callbacks are mutated during a callback
      execution. Patch by Bénédikt Tran.
    - gh-143200: xml.etree.ElementTree: fix use-after-free
      crashes in __getitem__() and __setitem__() methods of
      Element when the element is concurrently mutated. Patch by
      Bénédikt Tran.
    - gh-142195: Updated timeout evaluation logic in subprocess
      to be compatible with deterministic environments like
      Shadow where time moves exactly as requested.

      to report the correct offset and size calculation.
    - gh-143145: Fixed a possible reference leak in ctypes when
      constructing results with multiple output parameters on
      error.
    - gh-122431: Corrected the error message in
      readline.append_history_file() to state that nelements must
      be non-negative instead of positive.
    - gh-143004: Fix a potential use-after-free in
      collections.Counter.update() when user code mutates the
      Counter during an update.
    - gh-143046: The asyncio REPL no longer prints copyright and
      version messages in the quiet mode (-q). Patch by Bartosz
      Sławecki.
    - gh-140648: The asyncio REPL now respects the -I flag
      (isolated mode). Previously, it would load and execute
      PYTHONSTARTUP even if the flag was set. Contributed by
      Bartosz Sławecki.
    - gh-142991: Fixed socket operations such as recvfrom() and
      sendto() for FreeBSD divert(4) socket.
    - gh-143010: Fixed a bug in mailbox where the precise timing
      of an external event could result in the library opening an
      existing file instead of a file it expected to create.
    - gh-142881: Fix concurrent and reentrant call of
      atexit.unregister().
    - gh-112127: Fix possible use-after-free in
      atexit.unregister() when the callback is unregistered
      during comparison.
    - gh-142783: Fix zoneinfo use-after-free with descriptor
      _weak_cache. a descriptor as _weak_cache could cause
      crashes during object creation. The fix ensures proper
      reference counting for descriptor-provided objects.
    - gh-142754: Add the ownerDocument attribute to
      xml.dom.minidom elements and attributes created by directly
      instantiating the Element or Attr class. Note that this way
      of creating nodes is not supported; creator functions like
      xml.dom.Document.documentElement() should be used instead.
    - gh-142784: The asyncio REPL now properly closes the loop
      upon the end of interactive session. Previously, it could
      cause surprising warnings. Contributed by Bartosz Sławecki.
    - gh-142555: array: fix a crash in a[i] = v when converting
      i to an index via i.__index__ or i.__float__ mutates the
      array.
    - gh-142594: Fix crash in TextIOWrapper.close() when the
      underlying buffer’s closed property calls detach().
    - gh-142451: hmac: Ensure that the HMAC.block_size attribute
      is correctly copied by HMAC.copy. Patch by Bénédikt Tran.
    - gh-142495: collections.defaultdict now prioritizes
      __setitem__() when inserting default values from
      default_factory. This prevents race conditions where
      a default value would overwrite a value set before
      default_factory returns.
    - gh-142651: unittest.mock: fix a thread safety issue where
      Mock.call_count may return inaccurate values when the mock
      is called concurrently from multiple threads.
    - gh-142595: Added type check during initialization of the
      decimal module to prevent a crash in case of broken stdlib.
      Patch by Sergey B Kirpichev.

      finalization in asyncio. Patch by Kumar Aditya.
    - gh-123241: Avoid reference count operations in garbage
      collection of ctypes objects.
    - gh-142517: The non-compat32 email policies now correctly
      handle refolding encoded words that contain bytes that can
      not be decoded in their specified character set. Previously
      this resulted in an encoding exception during folding.
    - gh-112527: The help text for required options in argparse
      no longer extended with “ (default: None)”.
    - gh-142346: Fix usage formatting for mutually exclusive
      groups in argparse when they are preceded by positional
      arguments or followed or intermixed with other optional
      arguments.
    - gh-142315: Pdb can now run scripts from anonymous pipes
      used in process substitution. Patch by Bartosz Sławecki.
    - gh-142332: Fix usage formatting for positional arguments in
      mutually exclusive groups in argparse. in argparse.
    - gh-142282: Fix winreg.QueryValueEx() to not accidentally
      read garbage buffer under race condition.
    - gh-75949: Fix argparse to preserve | separators in mutually
      exclusive groups when the usage line wraps due to length.
    - gh-142267: Improve argparse performance by caching the
      formatter used for argument validation.
    - gh-68552: MisplacedEnvelopeHeaderDefect and Missing header
      name defects are now correctly passed to the handle_defect
      method of policy in FeedParser.
    - gh-142006: Fix a bug in the email.policy.default folding
      algorithm which incorrectly resulted in a doubled newline
      when a line ending at exactly max_line_length was followed
      by an unfoldable token.
    - gh-105836: Fix asyncio.run_coroutine_threadsafe() leaving
      underlying cancelled asyncio task running.
    - gh-139971: pydoc: Ensure that the link to the online
      documentation of a stdlib module is correct.
    - gh-139262: Some keystrokes can be swallowed in the new
      PyREPL on Windows, especially when used together with the
      ALT key. Fix by Chris Eibl.
    - gh-138897: Improved license/copyright/credits display in
      the REPL: now uses a pager.
    - gh-79986: Add parsing for References and In-Reply-To
      headers to the email library that parses the header content
      as lists of message id tokens. This prevents them from
      being folded incorrectly.
    - gh-136282: Add support for UNNAMED_SECTION when creating
      a section via the mapping protocol access
    - gh-109263: Starting a process from spawn context in
      multiprocessing no longer sets the start method globally.
    - gh-133253: Fix thread-safety issues in linecache.

      a failure has occurred.
  - IDLE
    - gh-143774: Better explain the operation of Format / Format
      Paragraph.
  - Documentation
    - gh-140806: Add documentation for enum.bin().
  - Core and Builtins

      opcode.
    - gh-141805: Fix crash in set when objects with the same hash
      are concurrently added to the set after removing an element
      with the same hash while the set still contains elements
      with the same hash.
    - gh-143670: Fixes a crash in ga_repr_items_list function.
    - gh-143377: Fix a crash in _interpreters.capture_exception()
      when the exception is incorrectly formatted. Patch by

      incorrectly syntax highlights text input as Python code.
      Contributed by Olga Matoula.
    - gh-143189: Fix crash when inserting a non-str key into
      a split table dictionary when the key matches an existing
      key in the split table but has no corresponding value in
      the dict.
    - gh-143228: Fix use-after-free in perf trampoline when
      toggling profiling while threads are running or during
      interpreter finalization with daemon threads active. The
      fix uses reference counting to ensure trampolines are not
      freed while any code object could still reference them.
      Pach by Pablo Galindo
    - gh-142664: Fix a use-after-free crash in
      memoryview.__hash__ when the __hash__ method of the
      referenced object mutates that object or the view. Patch by
      Bénédikt Tran.
    - gh-142557: Fix a use-after-free crash in bytearray.__mod__
      when the bytearray is mutated while formatting the %-style
      arguments. Patch by Bénédikt Tran.
    - gh-143195: Fix use-after-free crashes in bytearray.hex()
      and memoryview.hex() when the separator’s __len__() mutates
      the original object. Patch by Bénédikt Tran.
    - gh-142975: Fix crash after unfreezing all objects tracked
      by the garbage collector on the free threaded build.
    - gh-143135: Set sys.flags.inspect to 1 when PYTHONINSPECT is
      0. Previously, it was set to 0 in this case.
    - gh-143003: Fix an overflow of the shared empty buffer in
      bytearray.extend() when __length_hint__() returns 0 for
      non-empty iterator.
    - gh-143006: Fix a possible assertion error when comparing
      negative non-integer float and int with the same number of
      bits in the integer part.
    - gh-143057: Avoid locking in PyTraceMalloc_Track() and
      PyTraceMalloc_Untrack() when tracemalloc is not enabled.
    - gh-142776: Fix a file descriptor leak in import.c
    - gh-142829: Fix a use-after-free crash in
      contextvars.Context comparison when a custom __eq__ method
      modifies the context via set().
    - gh-142766: Clear the frame of a generator when
      generator.close() is called.
    - gh-142737: Tracebacks will be displayed in fallback mode
      even if io.open() is lost. Previously, this would crash the
      interpreter. Patch by Bartosz Sławecki.
    - gh-142554: Fix a crash in divmod() when
      _pylong.int_divmod() does not return a tuple of length two
      exactly. Patch by Bénédikt Tran.
    - gh-142560: Fix use-after-free in bytearray search-like
      methods (find(), count(), index(), rindex(), and rfind())
      by marking the storage as exported which causes
      reallocation attempts to raise BufferError. For contains(),
      split(), and rsplit() the buffer protocol is used for this.
    - gh-142531: Fix a free-threaded GC performance regression.
      If there are many untracked tuples, the GC will run too
      often, resulting in poor performance. The fix is to include
      untracked tuples in the “long lived” object count. The
      number of frozen objects is also now included since the
      free-threaded GC must scan those too.
    - gh-142402: Fix reference counting when adjacent literal
      parts are merged while constructing
      string.templatelib.Template, preventing the displaced
      string object from leaking.
    - gh-133932: Fix crash in the free threading build when
      clearing frames that hold tagged integers.
    - gh-142343: Fix SIGILL crash on m68k due to incorrect
      assembly constraint.
    - gh-100964: Fix reference cycle in exhausted generator
      frames. Patch by Savannah Ostrowski.
    - gh-69605: Fix edge-cases around already imported modules in
      the REPL auto-completion of imports.
    - gh-138568: Adjusted the built-in help() function so that
      empty inputs are ignored in interactive mode.
    - gh-137007: Fix a bug during JIT compilation failure which
      caused garbage collection debug assertions to fail.
  - C API
    - gh-142589: Fix
      PyUnstable_Object_IsUniqueReferencedTemporary() handling of
      tagged ints on the interpreter stack.
    - gh-142571: PyUnstable_CopyPerfMapFile() now checks that
      opening the file succeeded before flushing.
  - Build
    - gh-142454: When calculating the digest of the JIT stencils
      input, sort the hashed files by filenames before adding
      their content to the hasher. This ensures deterministic
      hash input and hence deterministic hash, independent on
      filesystem order.
    - gh-141808: When running make clean-retain-profile, keep the
      generated JIT stencils. That way, the stencils are not
      generated twice when Profile-guided optimization (PGO) is
      used. It also allows distributors to supply their own
      pre-built JIT stencils.
    - gh-138061: Ensure reproducible builds by making JIT stencil
      header generation deterministic.
Remove upstreamed patches:
  - CVE-2024-6923-follow-up-EOL-email-headers.patch
  - CVE-2025-11468-email-hdr-fold-comment.patch
  - CVE-2026-0672-http-hdr-inject-cookie-Morsel.patch
  - gh138131-exclude-pycache-from-digest.patch
      by a factor of 3.8x (bsc#1257031, CVE-2026-0672).
