* GH-111485: Remove some special cases from the code generator and bytecodes.c ↵Mark Shannon2023-10-314-10/+89
| | | | (GH-111540)
* GH-111485: Increment `next_instr` consistently at the start of the ↵Mark Shannon2023-10-315-493/+969
| | | | instruction. (GH-111486)
* gh-109329: Count tier2 opcode misses (#110561)Michael Droettboom2023-10-312-1/+5
| | | This keeps a separate 'miss' counter for each micro-opcode, incremented whenever a guard uop takes a deoptimization side exit.
* gh-76785: Move the Cross-Interpreter Code to Its Own File (gh-111502)Eric Snow2023-10-302-591/+631
| | | This is partly to clear this stuff out of pystate.c, but also in preparation for moving some code out of _xxsubinterpretersmodule.c. This change also moves this stuff to the internal API (new: Include/internal/pycore_crossinterp.h). @vstinner did this previously and I undid it. Now I'm re-doing it. :/

| | | | | | | | * gh-106320: Re-add _PyLong_FromByteArray(), _PyLong_AsByteArray() and _PyLong_GCD() to the public header files since they are used by third-party packages and there is no efficient replacement. See https://github.com/python/cpython/issues/111140 See https://github.com/python/cpython/issues/111139 * gh-111262: Re-add _PyDict_Pop() to have a C-API until a new public one is designed.

|

| | | | and globally. (GH-110384)
* gh-67565: Remove redundant C-contiguity checks (GH-105521)Furkan Onder2023-10-233-21/+8
| | | | Co-authored-by: Stefan Krah <skrah@bytereef.org>

|
* gh-84570: Send-Wait Fixes for _xxinterpchannels (gh-111006)Eric Snow2023-10-171-0/+50
| | | | | There were a few things I did in gh-110565 that need to be fixed. I also forgot to add tests in that PR. (Note that this PR exposes a refleak introduced by gh-110246. I'll take care of that separately.)
* gh-109693: Remove pycore_atomic.h (gh-110992)Donghee Na2023-10-172-2/+0

Replace _PyArg_UnpackStack() with PyArg_ParseTuple(). * _testcapi: add PYTESTCAPI_NEED_INTERNAL_API macro which is defined by _testcapi sub-modules which need the internal C API (pycore_modsupport.h): exceptions.c, float.c, vectorcall.c, watchers.c. * Remove Include/cpython/modsupport.h header file. Include/modsupport.h no longer includes the removed header file. * Fix mypy clinic.py

| | | | | | | (GH-110816) It already mostly worked, except in the case when invalid keyword argument with non-ASCII name was passed to function with non-ASCII parameter names. Then it crashed in the debug mode.

* gh-104169: Refactor tokenizer into lexer and wrappers (#110684)Lysandros Nikolaou2023-10-111-1/+3
| | | | | | | | | | | * The lexer, which include the actual lexeme producing logic, goes into the `lexer` directory. * The wrappers, one wrapper per input mode (file, string, utf-8, and readline), go into the `tokenizer` directory and include logic for creating a lexer instance and managing the buffer for different modes. --------- Co-authored-by: Pablo Galindo <pablogsal@gmail.com> Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com>

* gh-85283: Add PySys_AuditTuple() function (#108965)Victor Stinner2023-10-051-3/+19
| | | | | | sys.audit() now has assertions to check that the event argument is not NULL and that the format argument does not use the "N" format. Add tests on PySys_AuditTuple().
* gh-109549: Add new states to PyThreadState to support PEP 703 (gh-109915)Sam Gross2023-10-053-91/+95
| | | This adds a new field 'state' to PyThreadState that can take on one of three values: _Py_THREAD_ATTACHED, _Py_THREAD_DETACHED, or _Py_THREAD_GC. The "attached" and "detached" states correspond closely to acquiring and releasing the GIL. The "gc" state is current unused, but will be used to implement stop-the-world GC for --disable-gil builds in the near future.
* gh-109329: Add stat for "trace too short" (GH-110402)Michael Droettboom2023-10-052-0/+2
