* gh-115999: Specialize loading attributes from modules in free-threaded ↵mpage2024-12-132-0/+19
| | | | | | | | | builds (#127711) We use the same approach that was used for specialization of LOAD_GLOBAL in free-threaded builds: _CHECK_ATTR_MODULE is renamed to _CHECK_ATTR_MODULE_PUSH_KEYS; it pushes the keys object for the following _LOAD_ATTR_MODULE_FROM_KEYS (nee _LOAD_ATTR_MODULE). This arrangement avoids having to recheck the keys version. _LOAD_ATTR_MODULE is renamed to _LOAD_ATTR_MODULE_FROM_KEYS; it loads the value from the keys object pushed by the preceding _CHECK_ATTR_MODULE_PUSH_KEYS at the cached index.

* gh-127330: Update for OpenSSL 3.4 & document+improve the update process ↵Petr Viktorin2024-11-283-6/+34
| | | | | | | | | | | | | | | | | (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-126612: Include stack effects of uops when computing maximum stack depth ↵mpage2024-11-262-22/+134

* gh-127022: Simplify `PyStackRef_FromPyObjectSteal` (#127024)Sam Gross2024-11-221-1/+4
| | | | | | | | | This gets rid of the immortal check in `PyStackRef_FromPyObjectSteal()`. Overall, this improves performance about 2% in the free threading build. This also renames `PyStackRef_Is()` to `PyStackRef_IsExactly()` because the macro requires that the tag bits of the arguments match, which is only true in certain special cases.
* gh-126700: pygettext: Support more gettext functions (GH-126912)Tomas R.2024-11-221-73/+171
| | | | Support multi-argument gettext functions: ngettext(), pgettext(), dgettext(), etc.
* Allow local use of `static PyMutex` in the C analyzer (#127102)Peter Bierma2024-11-222-1/+14

* gh-115999: Specialize `LOAD_GLOBAL` in free-threaded builds (#126607)mpage2024-11-211-0/+3
| | | | | | | | | | | | | | Enable specialization of LOAD_GLOBAL in free-threaded builds. Thread-safety of specialization in free-threaded builds is provided by the following: A critical section is held on both the globals and builtins objects during specialization. This ensures we get an atomic view of both builtins and globals during specialization. Generation of new keys versions is made atomic in free-threaded builds. Existing helpers are used to atomically modify the opcode. Thread-safety of specialized instructions in free-threaded builds is provided by the following: Relaxed atomics are used when loading and storing dict keys versions. This avoids potential data races as the dict keys versions are read without holding the dictionary's per-object lock in version guards. Dicts keys objects are passed from keys version guards to the downstream uops. This ensures that we are loading from the correct offset in the keys object. Once a unicode key has been stored in a keys object for a combined dictionary in free-threaded builds, the offset that it is stored in will never be reused for a different key. Once the version guard passes, we know that we are reading from the correct offset. The dictionary read fast-path is used to read values from the dictionary once we know the correct offset.
* gh-126316: Make grp.getgrall() thread-safe: add a mutex (#127055)Victor Stinner2024-11-211-0/+1
| | | | grpmodule.c is no longer built with the limited C API, since PyMutex is excluded from the limited C API.

* gh-126691: Remove --with-emscripten-target (#126787)Hood Chatham2024-11-162-8/+8
| | | | | This unifies the code for nodejs and the code for the browser. After this commit, the browser example doesn't work; this will be fixed in a subsequent update.

* gh-126807: pygettext: Do not attempt to extract messages from function ↵Tomas R.2024-11-141-0/+6
| | | | | | | | | | | | | | | | 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.

| | | | | Add emscripten.py script to automate emscripten build. This is modeled heavily on `Tools/wasm/wasi.py`. This will form the basis of an Emscripten build bot.

| | | | | | | | | specific (GH-126552) Eventually wasm32-wasi will represent WASI 1.0, and so it's currently deprecated so it can be used for that eventual purpose. wasm32-wasip1 is also more specific to what version of WASI is currently supported. --------- Co-authored-by: Erlend E. Aasland <erlend.aasland@protonmail.com>
* gh-122943: Rework support of var-positional parameter in Argument Clinic ↵Serhiy Storchaka2024-11-076-84/+156
| | | | | | | | | | | | | | | | | | (GH-122945) Move creation of a tuple for var-positional parameter out of _PyArg_UnpackKeywordsWithVararg(). Merge _PyArg_UnpackKeywordsWithVararg() with _PyArg_UnpackKeywords(). Add a new parameter in _PyArg_UnpackKeywords(). The "parameters" and "converters" attributes of ParseArgsCodeGen no longer contain the var-positional parameter. It is now available as the "varpos" attribute. Optimize code generation for var-positional parameter and reuse the same generating code for functions with and without keyword parameters. Add special converters for var-positional parameter. "tuple" represents it as a Python tuple and "array" represents it as a continuous array of PyObject*. "object" is a temporary alias of "tuple".
* gh-76785: Minor Cleanup of "Cross-interpreter" Code (gh-126457)Eric Snow2024-11-071-0/+1
| | | | | | | | The primary objective here is to allow some later changes to be cleaner. Mostly this involves renaming things and moving a few things around. * CrossInterpreterData -> XIData * crossinterpdatafunc -> xidatafunc * split out pycore_crossinterp_data_registry.h * add _PyXIData_lookup_t

| | | | (#126369)
* gh-115999: Implement thread-local bytecode and enable specialization for ↵mpage2024-11-041-1/+22
| | | | | | | | | `BINARY_OP` (#123926) Each thread specializes a thread-local copy of the bytecode, created on the first RESUME, in free-threaded builds. All copies of the bytecode for a code object are stored in the co_tlbc array on the code object. Threads reserve a globally unique index identifying its copy of the bytecode in all co_tlbc arrays at thread creation and release the index at thread destruction. The first entry in every co_tlbc array always points to the "main" copy of the bytecode that is stored at the end of the code object. This ensures that no bytecode is copied for programs that do not use threads. Thread-local bytecode can be disabled at runtime by providing either -X tlbc=0 or PYTHON_TLBC=0. Disabling thread-local bytecode also disables specialization. Concurrent modifications to the bytecode made by the specializing interpreter and instrumentation use atomics, with specialization taking care not to overwrite an instruction that was instrumented concurrently.
