Victor Stinner	c4e7d245d6	gh-138342: Move _PyObject_VisitType() to the internal C API (#139734)	2025-10-08 12:10:58 +02:00
Peter Bierma	4f6ecd10c2	gh-138342: Use a common utility for visiting an object's type (GH-138343) ... Add `_PyObject_VisitType` in place of `tp_traverse` functions that only visit the object's type.	2025-09-01 16:20:33 +00:00
Bénédikt Tran	fe0e921817	gh-131876: Revert "gh-131876: extract _hashlib helpers into a separate directory (#136995) (#137307) ... Revert "gh-131876: extract `_hashlib` helpers into a separate directory (#136995)" This reverts commit 45138d3584.	2025-08-01 10:45:40 -07:00
Bénédikt Tran	45138d3584	gh-131876: extract _hashlib helpers into a separate directory (#136995) ... The `Modules/hashlib.h` helper file is now removed and split into multiple files: * `Modules/_hashlib/hashlib_buffer.[ch]` -- Utilities for getting a buffer view and handling buffer inputs. * `Modules/_hashlib/hashlib_fetch.h` -- Utilities used when fetching a message digest from a digest-like identifier. Currently, this file only contains common error messages as the fetching API is not yet implemented. * `Modules/_hashlib/hashlib_mutex.h` -- Utilities for managing the lock on cryptographic hash objects.	2025-07-28 11:28:48 +02:00
Bénédikt Tran	621a8bd6a8	gh-135532: cleanup clinic module directives for cryptographic modules (#135822)	2025-06-22 20:04:38 +00:00
Bénédikt Tran	e7295a89b8	gh-135239: simpler use of mutexes in cryptographic modules (#135267)	2025-06-22 16:59:57 +02:00
Bénédikt Tran	c6e63d9d35	gh-134696: align OpenSSL and HACL*-based hash functions constructors AC signatures (#134713) ... OpenSSL and HACL*-based hash functions constructors now support both `data` and `string` parameters. Previously these constructor functions inconsistently supported sometimes `data` and sometimes `string`, while the documentation expected `data` to be given in all cases.	2025-05-31 09:37:47 +02:00
Bénédikt Tran	3695ba93d5	gh-132993: expose HASHLIB_GIL_MINSIZE to private extension modules (#132999)	2025-04-27 22:20:15 +00:00
Bénédikt Tran	261633bd3f	gh-131316: handle NULL values returned by HACL* functions (#131324) ... - Handle NULL returned by allocation functions. - Handle NULL returned by copy functions. - Suppress unused impossible return codes.	2025-03-17 11:10:39 +01:00
Victor Stinner	9d759b63d8	gh-111178: Change Argument Clinic signature for METH_O (#130682) ... Use "PyObject*" for METH_O functions to fix an undefined behavior.	2025-03-11 16:33:36 +01:00
Bénédikt Tran	922cfecbce	gh-111178: fix UBSan failures in Modules/{blake2,md5,sha1,sha2,sha3}module.c (GH-128248) ... - fix UBSan failures in `blake2module.c` - fix UBSan failures in `md5module.c` - fix UBSan failures in `sha1module.c` - fix UBSan failures in `sha2module.c` - fix UBSan failures in `sha3module.c` Cosmetics: - suppress unused return values - remove redundant casts in constructors - suppress unused parameters in `{md5,sha*,blake2}module.c`	2025-01-27 14:50:58 +01:00
Brett Simmers	c2627d6eea	gh-116322: Add Py_mod_gil module slot (#116882) ... 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).	2024-05-03 11:30:55 -04:00
Jonathan Protzenko	872e212378	gh-99108: Refresh HACL*; update modules accordingly; fix namespacing (GH-117237) ... Pulls in a new update from https://github.com/hacl-star/hacl-star and fixes our C "namespacing" done by `Modules/_hacl/refresh.sh`.	2024-03-26 00:35:26 +00:00
Tomas R	a6465605c1	gh-111916: Make hashlib related modules thread-safe without the GIL (#111981) ... Always use an individual lock on hash objects when in free-threaded builds. Fixes #111916	2023-11-15 23:53:38 +00:00
Victor Stinner	1a3faba9f1	gh-106869: Use new PyMemberDef constant names (#106871) ... * Remove '#include "structmember.h"'. * If needed, add <stddef.h> to get offsetof() function. * Update Parser/asdl_c.py to regenerate Python/Python-ast.c. * Replace: * T_SHORT => Py_T_SHORT * T_INT => Py_T_INT * T_LONG => Py_T_LONG * T_FLOAT => Py_T_FLOAT * T_DOUBLE => Py_T_DOUBLE * T_STRING => Py_T_STRING * T_OBJECT => _Py_T_OBJECT * T_CHAR => Py_T_CHAR * T_BYTE => Py_T_BYTE * T_UBYTE => Py_T_UBYTE * T_USHORT => Py_T_USHORT * T_UINT => Py_T_UINT * T_ULONG => Py_T_ULONG * T_STRING_INPLACE => Py_T_STRING_INPLACE * T_BOOL => Py_T_BOOL * T_OBJECT_EX => Py_T_OBJECT_EX * T_LONGLONG => Py_T_LONGLONG * T_ULONGLONG => Py_T_ULONGLONG * T_PYSSIZET => Py_T_PYSSIZET * T_NONE => _Py_T_NONE * READONLY => Py_READONLY * PY_AUDIT_READ => Py_AUDIT_READ * READ_RESTRICTED => Py_AUDIT_READ * PY_WRITE_RESTRICTED => _Py_WRITE_RESTRICTED * RESTRICTED => (READ_RESTRICTED | _Py_WRITE_RESTRICTED)	2023-07-25 15:28:30 +02:00
Jonathan Protzenko	160321e530	gh-99108: Refresh HACL* (#104808) ... Refresh HACL* from upstream to improve SHA2 performance and fix a 32-bit issue in SHA3.	2023-05-24 13:30:11 -07:00
Gregory P. Smith	2e5d8a90aa	gh-99108: Release the GIL around hashlib built-in computation (#104675) ... This matches the GIL releasing behavior of our existing `_hashopenssl` module, extending it to the HACL* built-ins. Includes adding comments to better describe the ENTER/LEAVE macros purpose and explain the lock strategy in both existing and new code.	2023-05-23 00:06:41 +00:00
Eric Snow	a9c6e0618f	gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205) ... Here we are doing no more than adding the value for Py_mod_multiple_interpreters and using it for stdlib modules. We will start checking for it in gh-104206 (once PyInterpreterState.ceval.own_gil is added in gh-104204).	2023-05-05 21:11:27 +00:00
Erlend E. Aasland	568fc0dee4	gh-101476: Use _PyType_GetModuleState where applicable (#102188)	2023-02-24 21:16:29 +01:00
Gregory P. Smith	0b13575e74	gh-99108: Refactor _sha256 & _sha512 into _sha2. (#101924) ... This merges their code. They're backed by the same single HACL* static library, having them be a single module simplifies maintenance. This should unbreak the wasm enscripten builds that currently fail due to linking in --whole-archive mode and the HACL* library appearing twice. Long unnoticed error fixed: _sha512.SHA384Type was doubly assigned and was actually SHA512Type. Nobody depends on those internal names. Also rename LIBHACL_ make vars to LIBHACL_SHA2_ in preperation for other future HACL things.	2023-02-15 22:08:20 -08:00
