* gh-99113: Add Py_MOD_PER_INTERPRETER_GIL_SUPPORTED (gh-104205)Eric Snow2023-05-051-0/+1
| | | 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).
* gh-99300: Use Py_NewRef() in Modules/ directory (#99468)Victor Stinner2022-11-141-52/+27
| | | | Replace Py_INCREF() and Py_XINCREF() with Py_NewRef() and Py_XNewRef() in test C files of the Modules/ directory.
* gh-98740: Fix validation of conditional expressions in RE (GH-98764)Serhiy Storchaka2022-11-031-27/+29
| | | | | | | | | | | In very rare circumstances the JUMP opcode could be confused with the argument of the opcode in the "then" part which doesn't end with the JUMP opcode. This led to incorrect detection of the final JUMP opcode and incorrect calculation of the size of the subexpression. NOTE: Changed return value of functions _validate_inner() and _validate_charset() in Modules/_sre/sre.c. Now they return 0 on success, -1 on failure, and 1 if the last op is JUMP (which usually is a failure). Previously they returned 1 on success and 0 on failure.
* gh-91524: Speed up the regular expression substitution (#91525)Serhiy Storchaka2022-10-234-43/+329
| | | | | | | | | Functions re.sub() and re.subn() and corresponding re.Pattern methods are now 2-3 times faster for replacement strings containing group references. Closes #91524 Primarily authored by serhiy-storchaka Serhiy Storchaka Minor-cleanups-by: Gregory P. Smith [Google] <greg@krypto.org>
* gh-97669: Create Tools/build/ directory (#97963)Victor Stinner2022-10-172-2/+2
| | | | | | | | | | | | | | | | | | | | | | | Create Tools/build/ directory. Move the following scripts from Tools/scripts/ to Tools/build/: * check_extension_modules.py * deepfreeze.py * freeze_modules.py * generate_global_objects.py * generate_levenshtein_examples.py * generate_opcode_h.py * generate_re_casefix.py * generate_sre_constants.py * generate_stdlib_module_names.py * generate_token.py * parse_html5_entities.py * smelly.py * stable_abi.py * umarshal.py * update_file.py * verify_ensurepip_wheels.py Update references to these scripts.

* gh-90928: Statically Initialize the Keywords Tuple in Clinic-Generated Code ↵Eric Snow2022-08-111-14/+449
| | | | | | | | | | | | | | | | (gh-95860) We only statically initialize for core code and builtin modules. Extension modules still create the tuple at runtime. We'll solve that part of interpreter isolation separately. This change includes generated code. The non-generated changes are in: * Tools/clinic/clinic.py * Python/getargs.c * Include/cpython/modsupport.h * Makefile.pre.in (re-generate global strings after running clinic) * very minor tweaks to Modules/_codecsmodule.c and Python/Python-tokenize.c All other changes are generated code (clinic, global strings).

| | | | | | | | | | | | terminated by a signal or allocation failure (GH-32283) (#93882) Revert "bpo-23689: re module, fix memory leak when a match is terminated by a signal or memory allocation failure (GH-32283)" This reverts commit 6e3eee5c11b539e9aab39cff783acf57838c355a. Manual fixups to increase the MAGIC number and to handle conflicts with a couple of changes that landed after that. Thanks for reviews by Ma Lin and Serhiy Storchaka.
* gh-93741: Add private C API _PyImport_GetModuleAttrString() (GH-93742)Serhiy Storchaka2022-06-141-11/+1
| | | | | | It combines PyImport_ImportModule() and PyObject_GetAttrString() and saves 4-6 lines of code on every use. Add also _PyImport_GetModuleAttr() which takes Python strings as arguments.
* gh-92728: Restore re.template, but deprecate it (GH-93161)Miro Hrončok2022-05-252-0/+2
| | | | | | Revert "bpo-47211: Remove function re.template() and flag re.TEMPLATE (GH-32300)" This reverts commit b09184bf05b07b77c5ecfedd4daa846be3cbf0a9.
* gh-91320: Argument Clinic uses _PyCFunction_CAST() (#32210)Victor Stinner2022-05-031-19/+19
| | | | Replace "(PyCFunction)(void(*)(void))func" cast with _PyCFunction_CAST(func).
* gh-91583: AC: Fix regression for functions with defining_class (GH-91739)Serhiy Storchaka2022-04-301-44/+250
| | | | | Argument Clinic now generates the same efficient code as before adding the defining_class parameter.
* gh-91870: Remove unsupported SRE opcode CALL (GH-91872)Serhiy Storchaka2022-04-263-40/+37
| | | | | | | It was initially added to support atomic groups, but that support was never fully implemented, and CALL was only left in the compiler, but not interpreter and parser. ATOMIC_GROUP is now used to support atomic groups.
* gh-91616: re module, fix .fullmatch() mismatch when using Atomic Grouping or ↵Ma Lin2022-04-191-7/+7
| | | | | | | | | Possessive Quantifiers (GH-91681) These jumps should use DO_JUMP0() instead of DO_JUMP(): - JUMP_POSS_REPEAT_1 - JUMP_POSS_REPEAT_2 - JUMP_ATOMIC_GROUP
* bpo-47256: Increasing the depth of backtracking in RE (GH-32411)Ma Lin2022-04-182-44/+44
| | | | | | | | | | Limit the maximum capturing group to 2**30-1 on 64-bit platforms (it was 2**31-1). No change on 32-bit platforms (2**28-1). It allows to reduce the size of SRE(match_context): - On 32 bit platform: 36 bytes, no change. (msvc2022) - On 64 bit platform: 72 bytes -> 56 bytes. (msvc2022/gcc9.4) which leads to increasing the depth of backtracking.
* gh-91404: Use computed gotos and reduce indirection in re (#91495)Brandt Bucher2022-04-152-343/+452

* bpo-47152: Automatically regenerate sre_constants.h (GH-91439)Serhiy Storchaka2022-04-121-2/+2
| | | | | | | * Move the code for generating Modules/_sre/sre_constants.h from Lib/re/_constants.py into a separate script Tools/scripts/generate_sre_constants.py. * Add target `regen-sre` in the makefile. * Make target `regen-all` depending on `regen-sre`.
* bpo-47211: Remove function re.template() and flag re.TEMPLATE (GH-32300)Serhiy Storchaka2022-04-062-2/+0
| | | They were undocumented and never working.
* bpo-47152: Move sources of the _sre module into a subdirectory (GH-32290)Serhiy Storchaka2022-04-045-0/+5947
