* gh-86493: Modernize modules initialization code (GH-106858)Serhiy Storchaka2023-07-251-3/+1
| | | | | Use PyModule_Add() or PyModule_AddObjectRef() instead of soft deprecated PyModule_AddObject().
* gh-105235: Prevent reading outside buffer during mmap.find() (#105252)Dennis Sweeney2023-07-131-1/+6
| | | | | | | * Add a special case for s[-m:] == p in _PyBytes_Find * Add tests for _PyBytes_Find * Make sure that start <= end in mmap.find

* 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-102255: Improve build support for Windows API partitions (GH-102256)Max Bachmann2023-03-091-1/+7
| | | | | Add `MS_WINDOWS_DESKTOP`, `MS_WINDOWS_APPS`, `MS_WINDOWS_SYSTEM` and `MS_WINDOWS_GAMES` preprocessor definitions to allow switching off functionality missing from particular API partitions ("partitions" are used in Windows to identify overlapping subsets of APIs). CPython only officially supports `MS_WINDOWS_DESKTOP` and `MS_WINDOWS_SYSTEM` (APPS is included by normal desktop builds, but APPS without DESKTOP is not covered). Other configurations are a convenience for people building their own runtimes. `MS_WINDOWS_GAMES` is for the Xbox subset of the Windows API, which is also available on client OS, but is restricted compared to `MS_WINDOWS_DESKTOP`. These restrictions may change over time, as they relate to the build headers rather than the OS support, and so we assume that Xbox builds will use the latest available version of the GDK.
* gh-102336: Remove code specifically for handling Windows 7 (GH-102337)Max Bachmann2023-03-011-8/+8

* gh-81652: Add MAP_ALIGNED_SUPER FreeBSD and MAP_CONCEAL OpenBSD constants ↵Yeojin Kim2023-02-241-0/+6
| | | | (gh-102191)
* gh-99845: Use size_t type in __sizeof__() methods (#99846)Victor Stinner2022-11-301-5/+4
| | | | | | | | The implementation of __sizeof__() methods using _PyObject_SIZE() now use an unsigned type (size_t) to compute the size, rather than a signed type (Py_ssize_t). Cast explicitly signed (Py_ssize_t) values to unsigned type (Py_ssize_t).
* gh-99300: Replace Py_INCREF() with Py_NewRef() (#99513)Victor Stinner2022-11-161-2/+1
| | | | Replace Py_INCREF() and Py_XINCREF() using a cast with Py_NewRef() and Py_XNewRef().
* gh-44098: Release the GIL during mmap on Unix (GH-98146)Shantanu2022-10-101-3/+3
| | | | | This seems pretty straightforward. The issue mentions other calls in mmapmodule that we could release the GIL on, but those are in methods where we'd need to be careful to ensure that something sensible happens if those are called concurrently. In prior art, note that #12073 released the GIL for munmap. In a toy benchmark, I see the speedup you'd expect from doing this. Automerge-Triggered-By: GH:gvanrossum
* gh-94395: Remove unneeded module state from mmap (#94396)Erlend Egeberg Aasland2022-06-291-46/+8
|
* bpo-46848: Move _PyBytes_Find() to internal C API (GH-31642)Victor Stinner2022-03-021-0/+1
| | | | | | Move _PyBytes_Find() and _PyBytes_ReverseFind() functions to the internal C API. bytesobject.c now includes pycore_bytesobject.h.
* bpo-46848: Use stringlib/fastsearch in mmap (GH-31625)Dennis Sweeney2022-03-021-19/+13
| | | Speed up mmap.find(). Add _PyBytes_Find() and _PyBytes_ReverseFind().
* bpo-46541: Remove usage of _Py_IDENTIFIER from mmap module (GH-31375)Dong-hee Na2022-02-161-4/+1
|
* bpo-46541: Replace core use of _Py_IDENTIFIER() with statically initialized ↵Eric Snow2022-02-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | global objects. (gh-30928) We're no longer using _Py_IDENTIFIER() (or _Py_static_string()) in any core CPython code. It is still used in a number of non-builtin stdlib modules. The replacement is: PyUnicodeObject (not pointer) fields under _PyRuntimeState, statically initialized as part of _PyRuntime. A new _Py_GET_GLOBAL_IDENTIFIER() macro facilitates lookup of the fields (along with _Py_GET_GLOBAL_STRING() for non-identifier strings). https://bugs.python.org/issue46541#msg411799 explains the rationale for this change. The core of the change is in: * (new) Include/internal/pycore_global_strings.h - the declarations for the global strings, along with the macros * Include/internal/pycore_runtime_init.h - added the static initializers for the global strings * Include/internal/pycore_global_objects.h - where the struct in pycore_global_strings.h is hooked into _PyRuntimeState * Tools/scripts/generate_global_objects.py - added generation of the global string declarations and static initializers I've also added a --check flag to generate_global_objects.py (along with make check-global-objects) to check for unused global strings. That check is added to the PR CI config. The remainder of this change updates the core code to use _Py_GET_GLOBAL_IDENTIFIER() instead of _Py_IDENTIFIER() and the related _Py*Id functions (likewise for _Py_GET_GLOBAL_STRING() instead of _Py_static_string()). This includes adding a few functions where there wasn't already an alternative to _Py*Id(), replacing the _Py_Identifier * parameter with PyObject *. The following are not changed (yet): * stop using _Py_IDENTIFIER() in the stdlib modules * (maybe) get rid of _Py_IDENTIFIER(), etc. entirely -- this may not be doable as at least one package on PyPI using this (private) API * (maybe) intern the strings during runtime init https://bugs.python.org/issue46541
* bpo-46303: Move fileutils.h private functions to internal C API (GH-30484)Victor Stinner2022-01-111-0/+5
| | | | | | | | | | Move almost all private functions of Include/cpython/fileutils.h to the internal C API Include/internal/pycore_fileutils.h. Only keep _Py_fopen_obj() in Include/cpython/fileutils.h, since it's used by _testcapi which must not use the internal C API. Move EncodeLocaleEx() and DecodeLocaleEx() functions from _testcapi to _testinternalcapi, since the C API moved to the internal C API.

| | | | LARGE_INTEGER to Py_ssize_t (GH-30175)
* bpo-45621: Small changes to mmap (GH-29247)Tim Golden2021-10-291-16/+5
| | | | * Small tidy-ups / comments * Use randomized names when testing tagged mmaps to avoid any risk of parallel tests treading on each others' toes
* bpo-40915: Fix mmap resize bugs on Windows (GH-29213)Tim Golden2021-10-261-34/+95
| | | | | | | | | | | (original patch by eryksun) Correctly hand various failure modes when resizing an mmap on Windows: * Resizing a pagefile-backed mmap now creates a new mmap and copies data * Attempting to resize when another mapping is held on the same file raises an OSError * Attempting to resize a nametagged mmap raises an OSError if another mapping is held with the same nametag
* bpo-43908: Make heap types converted during 3.10 alpha immutable (GH-26351)Erlend Egeberg Aasland2021-06-171-1/+2

* bpo-30555: Fix WindowsConsoleIO fails in the presence of fd redirection ↵Segev Finer2021-04-231-6/+3
| | | | | | | | (GH-1927) This works by not caching the handle and instead getting the handle from the file descriptor each time, so that if the actual handle changes by fd redirection closing/opening the console handle beneath our feet, we will keep working correctly.

| | | These were added by mistake (see https://bugs.python.org/issue39481#msg366288).
* bpo-40268: Remove unused structmember.h includes (GH-19530)Victor Stinner2020-04-151-1/+1
| | | | | | If only offsetof() is needed: include stddef.h instead. When structmember.h is used, add a comment explaining that PyMemberDef is used.

* bpo-36648: fix mmap issue for VxWorks (GH-12394)Lihua Zhao2019-05-211-0/+7
| | | | | The mmap module set MAP_SHARED flag when map anonymous memory, however VxWorks only support MAP_PRIVATE when map anonymous memory, this commit clear MAP_SHARED and set MAP_PRIVATE.
* bpo-36946: Fix possible signed integer overflow when handling slices. (GH-13375)Zackery Spytz2019-05-171-2/+4
| | | | | | | The final addition (cur += step) may overflow, so use size_t for "cur". "cur" is always positive (even for negative steps), so it is safe to use size_t here. Co-Authored-By: Martin Panter <vadmium+py@gmail.com>
