* [3.13] gh-113993: Allow interned strings to be mortal, and fix related ↵Petr Viktorin2024-06-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | issues (GH-120520) (GH-120945) * Add an InternalDocs file describing how interning should work and how to use it. * Add internal functions to *explicitly* request what kind of interning is done: - `_PyUnicode_InternMortal` - `_PyUnicode_InternImmortal` - `_PyUnicode_InternStatic` * Switch uses of `PyUnicode_InternInPlace` to those. * Disallow using `_Py_SetImmortal` on strings directly. You should use `_PyUnicode_InternImmortal` instead: - Strings should be interned before immortalization, otherwise you're possibly interning a immortalizing copy. - `_Py_SetImmortal` doesn't handle the `SSTATE_INTERNED_MORTAL` to `SSTATE_INTERNED_IMMORTAL` update, and those flags can't be changed in backports, as they are now part of public API and version-specific ABI. * Add private `_only_immortal` argument for `sys.getunicodeinternedsize`, used in refleak test machinery. * Make sure the statically allocated string singletons are unique. This means these sets are now disjoint: - `_Py_ID` - `_Py_STR` (including the empty string) - one-character latin-1 singletons Now, when you intern a singleton, that exact singleton will be interned. * Add a `_Py_LATIN1_CHR` macro, use it instead of `_Py_ID`/`_Py_STR` for one-character latin-1 singletons everywhere (including Clinic). * Intern `_Py_STR` singletons at startup. * For free-threaded builds, intern `_Py_LATIN1_CHR` singletons at startup. * Beef up the tests. Cover internal details (marked with `@cpython_only`). * Add lots of assertions Co-authored-by: Eric Snow <ericsnowcurrently@gmail.com>
* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-0/+1
| | | | | | | | | | | | | | This PR adds the ability to enable the GIL if it was disabled at interpreter startup, and modifies the multi-phase module initialization path to enable the GIL when loading a module, unless that module's spec includes a slot indicating it can run safely without the GIL. PEP 703 called the constant for the slot `Py_mod_gil_not_used`; I went with `Py_MOD_GIL_NOT_USED` for consistency with gh-104148. A warning will be issued up to once per interpreter for the first GIL-using module that is loaded. If `-v` is given, a shorter message will be printed to stderr every time a GIL-using module is loaded (including the first one that issues a warning).

* gh-111926: Make weakrefs thread-safe in free-threaded builds (#117168)mpage2024-04-082-5/+4
| | | | | | | | | Most mutable data is protected by a striped lock that is keyed on the referenced object's address. The weakref's hash is protected using the weakref's per-object lock. Note that this only affects free-threaded builds. Apart from some minor refactoring, the added code is all either gated by `ifdef`s or is a no-op (e.g. `Py_BEGIN_CRITICAL_SECTION`).

* gh-111089: Use PyUnicode_AsUTF8() in Argument Clinic (#111585)Victor Stinner2023-11-013-87/+17
| | | | | | | Replace PyUnicode_AsUTF8AndSize() with PyUnicode_AsUTF8() to remove the explicit check for embedded null characters. The change avoids to have to include explicitly <string.h> to get the strlen() function when using a recent version of the limited C API.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move the following private functions and structures to pycore_modsupport.h internal C API: * _PyArg_BadArgument() * _PyArg_CheckPositional() * _PyArg_NoKeywords() * _PyArg_NoPositional() * _PyArg_ParseStack() * _PyArg_ParseStackAndKeywords() * _PyArg_Parser structure * _PyArg_UnpackKeywords() * _PyArg_UnpackKeywordsWithVararg() * _PyArg_UnpackStack() * _Py_ANY_VARARGS() Changes: * Python/getargs.h now includes pycore_modsupport.h to export functions. * clinic.py now adds pycore_modsupport.h when one of these functions is used. * Add pycore_modsupport.h includes when a C extension uses one of these functions. * Define Py_BUILD_CORE_MODULE in C extensions which now include directly or indirectly (via code generated by Argument Clinic) pycore_modsupport.h: * _csv * _curses_panel * _dbm * _gdbm * _multiprocessing.posixshmem * _sqlite.row * _statistics * grp * resource * syslog * _testcapi: bad_get() no longer uses METH_FASTCALL calling convention but METH_VARARGS. 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-107603: Argument Clinic: Only include pycore_gc.h if needed (#108726)Victor Stinner2023-08-316-30/+14
| | | | | | | | | | | | | | | | | | | | Argument Clinic now only includes pycore_gc.h if PyGC_Head is needed, and only includes pycore_runtime.h if _Py_ID() is needed. * Add 'condition' optional argument to Clinic.add_include(). * deprecate_keyword_use() includes pycore_runtime.h when using the _PyID() function. * Fix rendering of includes: comments start at the column 35. * Mark PC/clinic/_wmimodule.cpp.h and "Objects/stringlib/clinic/*.h.h" header files as generated in .gitattributes. Effects: * 42 header files generated by AC no longer include the internal C API, instead of 4 header files before. For example, Modules/clinic/_abc.c.h no longer includes the internal C API. * Fix _testclinic_depr.c.h: it now always includes pycore_runtime.h to get _Py_ID().
* gh-106320: Remove private _PyErr_ChainExceptions() (#108713)Victor Stinner2023-08-311-0/+2
| | | | | | | | | | | | | Remove _PyErr_ChainExceptions(), _PyErr_ChainExceptions1() and _PyErr_SetFromPyStatus() functions from the public C API. * Move the private _PyErr_ChainExceptions() and _PyErr_ChainExceptions1() function to the internal C API (pycore_pyerrors.h). * Move the private _PyErr_SetFromPyStatus() to the internal C API (pycore_initconfig.h). * No longer export the _PyErr_ChainExceptions() function. * Move run_in_subinterp_with_config() from _testcapi to _testinternalcapi.
