* [3.11] gh-107913: Fix possible losses of OSError error codes (GH-107930) ↵Serhiy Storchaka2023-08-271-0/+2
| | | | | | | | (GH-108524) Functions like PyErr_SetFromErrno() and SetFromWindowsErr() should be called immediately after using the C API which sets errno or the Windows error code. (cherry picked from commit 2b15536fa94d07e9e286826c23507402313ec7f4)

* 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-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.

* 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-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.

* bpo-39481: remove generic classes from ipaddress/mmap (GH-20045)Batuhan Taskaya2020-05-121-2/+0
| | | 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>

* Fix misleading mentions of tp_size in comments (GH-9093)Peter Eisentraut2018-09-101-1/+1
| | | | Many type object initializations labeled a field "tp_size" in the comment, but the name of that field is tp_basicsize.
* bpo-2122: Make mmap.flush() behave same on all platforms (GH-8692)Berker Peksag2018-08-221-4/+7

* bpo-33021: Release the GIL during fstat() calls (GH-6019)Nir Soffer2018-03-111-2/+9
| | | | | | | | | | | | | | fstat may block for long time if the file descriptor is on a non-responsive NFS server, hanging all threads. Most fstat() calls are handled by _Py_fstat(), releasing the GIL internally, but but _Py_fstat_noraise() does not release the GIL, and most calls release the GIL explicitly around it. This patch fixes last 2 calls to _Py_fstat_no_raise(), avoiding hangs when calling: - mmap.mmap() - os.urandom() - random.seed()
