* gh-127330: Update for OpenSSL 3.4 & document+improve the update process ↵Petr Viktorin2024-11-281-3/+1
| | | | | | | | | | | | | | | | | (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-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-122943: Rework support of var-positional parameter in Argument Clinic ↵Serhiy Storchaka2024-11-071-1/+1
| | | | | | | | | | | | | | | | | | (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
* gh-99108: Cleanup references to inexisting `Modules/_blake2`. (GH-126270)Bénédikt Tran2024-11-012-4/+0
| | | | | | | | | * Remove references to `Modules/_blake2`. * Remove `Modules/_blake2` entry from CODEOWNERS The folder does not exist anymore. * Remove `Modules/_blake2` entry from `Tools/c-analyzer/TODO`
* gh-124872: Replace enter/exit events with "switched" (#125532)Kirill Podoprigora2024-10-161-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | Users want to know when the current context switches to a different context object. Right now this happens when and only when a context is entered or exited, so the enter and exit events are synonymous with "switched". However, if the changes proposed for gh-99633 are implemented, the current context will also switch for reasons other than context enter or exit. Since users actually care about context switches and not enter or exit, replace the enter and exit events with a single switched event. The former exit event was emitted just before exiting the context. The new switched event is emitted after the context is exited to match the semantics users expect of an event with a past-tense name. If users need the ability to clean up before the switch takes effect, another event type can be added in the future. It is not added here because YAGNI. I skipped 0 in the enum as a matter of practice. Skipping 0 makes it easier to troubleshoot when code forgets to set zeroed memory, and it aligns with best practices for other tools (e.g., https://protobuf.dev/programming-guides/dos-donts/#unspecified-enum).

* gh-99108: Add HACL* Blake2 implementation to hashlib (GH-119316)Jonathan Protzenko2024-08-131-0/+3
| | | | | | | This replaces the existing hashlib Blake2 module with a single implementation that uses HACL\*'s Blake2b/Blake2s implementations. We added support for all the modes exposed by the Python API, including tree hashing, leaf nodes, and so on. We ported and merged all of these changes upstream in HACL\*, added test vectors based on Python's existing implementation, and exposed everything needed for hashlib. This was joint work done with @R1kM. See the PR for much discussion and benchmarking details. TL;DR: On many systems, 8-50% faster (!) than `libb2`, on some systems it appeared 10-20% slower than `libb2`.

* gh-71587: Drop local reference cache to `_strptime` module in `_datetime` ↵neonene2024-06-121-1/+0
| | | | | (gh-120224) The _strptime module object was cached in a static local variable (in the datetime.strptime() implementation). That's a problem when it crosses isolation boundaries, such as reinitializing the runtme or between interpreters. This change fixes the problem by dropping the static variable, instead always relying on the normal sys.modules cache (via PyImport_Import()).
* gh-117398: Use Per-Interpreter State for the _datetime Static Types (gh-119929)Eric Snow2024-06-032-0/+2
| | | | | | | We make use of the same mechanism that we use for the static builtin types. This required a few tweaks. The relevant code could use some cleanup but I opted to avoid the significant churn in this change. I'll tackle that separately. This change is the final piece needed to make _datetime support multiple interpreters. I've updated the module slot accordingly.
* gh-119396: Optimize unicode_repr() (#119617)Victor Stinner2024-05-281-0/+1

* gh-116738: Make `_codecs` module thread-safe (#117530)Brett Simmers2024-05-021-1/+1
| | | | | | | | | | | | | | | The module itself is a thin wrapper around calls to functions in `Python/codecs.c`, so that's where the meaningful changes happened: - Move codecs-related state that lives on `PyInterpreterState` to a struct declared in `pycore_codecs.h`. - In free-threaded builds, add a mutex to `codecs_state` to synchronize operations on `search_path`. Because `search_path_mutex` is used as a normal mutex and not a critical section, we must be extremely careful with operations called while holding it. - The codec registry is explicitly initialized as part of `_PyUnicode_InitEncodings` to simplify thread-safety.

* gh-76785: Drop PyInterpreterID_Type (gh-117101)Eric Snow2024-03-211-1/+0
| | | I added it quite a while ago as a strategy for managing interpreter lifetimes relative to the PEP 554 (now 734) implementation. Relatively recently I refactored that implementation to no longer rely on InterpreterID objects. Thus now I'm removing it.
* gh-115754: Add Py_GetConstant() function (#116883)Victor Stinner2024-03-211-0/+1
| | | | | | | | | | | | Add Py_GetConstant() and Py_GetConstantBorrowed() functions. In the limited C API version 3.13, getting Py_None, Py_False, Py_True, Py_Ellipsis and Py_NotImplemented singletons is now implemented as function calls at the stable ABI level to hide implementation details. Getting these constants still return borrowed references. Add _testlimitedcapi/object.c and test_capi/test_object.py to test Py_GetConstant() and Py_GetConstantBorrowed() functions.
* gh-85283: Convert grp extension to the limited C API (#116611)Victor Stinner2024-03-121-0/+2

| | | | | | | | | | | | | Add a new C extension "_testlimitedcapi" which is only built with the limited C API. Move heaptype_relative.c and vectorcall_limited.c from Modules/_testcapi/ to Modules/_testlimitedcapi/. * configure: add _testlimitedcapi test extension. * Update generate_stdlib_module_names.py. * Update make check-c-globals.
