* [3.13] gh-130163: Fix crashes related to PySys_GetObject() (GH-130503) ↵Serhiy Storchaka2025-02-251-2/+12
| | | | | | | | | | (GH-130556) The use of PySys_GetObject() and _PySys_GetAttr(), which return a borrowed reference, has been replaced by using one of the following functions, which return a strong reference and distinguish a missing attribute from an error: _PySys_GetOptionalAttr(), _PySys_GetOptionalAttrString(), _PySys_GetRequiredAttr(), and _PySys_GetRequiredAttrString(). (cherry picked from commit 0ef4ffeefd1737c18dc9326133c7894d58108c2e)

| | | | | | | | | Tkinter (GH-120909) (GH-120938) Now the null character is always represented as \xc0\x80 for Tcl_NewStringObj(). (cherry picked from commit c38e2f64d012929168dfef7363c9e48bd1a6c731) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

| | | | | | | Accessing the Tkinter object's string representation no longer converts the underlying Tcl object to a string on Windows. (cherry picked from commit f4ddaa396715855ffbd94590f89ab7d55feeec07) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>

| | | | | | | | | * Add declaration of Tcl_AppInit(), missing in Tcl 9.0. * Use Tcl_Size instead of int where needed. (cherry picked from commit e0799352823289fafb8131341abd751923ee9c08) Co-authored-by: Christopher Chavez <chrischavez@gmx.us> Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
* [3.13] gh-103194: Fix Tkinter’s Tcl value type handling for Tcl 8.7/9.0 ↵Miss Islington (bot)2024-05-311-18/+32
| | | | | | | | | | | (GH-103846) (GH-119830) Some of standard Tcl types were renamed, removed, or no longer registered in Tcl 8.7/9.0. This change fixes automatic conversion of Tcl values to Python values to avoid returning a Tcl_Obj where the primary Python types (int, bool, str, bytes) were returned in older Tcl. (cherry picked from commit 94e9585e99abc2d060cedc77b3c03e06b4a0a9c4) Co-authored-by: Christopher Chavez <chrischavez@gmx.us>
* gh-66410: Do not stringify arguments of Tkinter callback (GH-98592)Serhiy Storchaka2024-05-071-7/+10
| | | | | | | | | Callbacks registered in the tkinter module now take arguments as various Python objects (int, float, bytes, tuple), not just str. To restore the previous behavior set tkinter module global wantobject to 1 before creating the Tk object or call the wantobject() method of the Tk object with argument 1. Calling it with argument 2 restores the current default behavior.
* gh-71592: Fix a leak in tkinter.Tk destructor when _debug is true (GH-118664)Serhiy Storchaka2024-05-061-0/+1

* gh-71592: Add ability to trace Tcl commands executed by Tkinter (GH-118291)Serhiy Storchaka2024-05-061-1/+147
| | | | | | | | | | | | This is an experimental feature, for internal use. Setting tkinter._debug = True before creating the root window enables printing every executed Tcl command (or a Tcl command equivalent to the used Tcl C API). This will help to convert a Tkinter example into Tcl script to check whether the issue is caused by Tkinter or exists in the underlying Tcl/Tk library.
* gh-116322: Rename PyModule_ExperimentalSetGIL to PyUnstable_Module_SetGIL ↵Petr Viktorin2024-05-061-1/+1

* gh-116322: Add Py_mod_gil module slot (#116882)Brett Simmers2024-05-031-0/+3
| | | | | | | | | | | | | | 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).

* gh-108765: Python.h no longer includes <ctype.h> (#108831)Victor Stinner2023-09-031-7/+6
| | | | | | | | | | | | | | | | | | | | | | | Remove <ctype.h> in C files which don't use it; only sre.c and _decimal.c still use it. Remove _PY_PORT_CTYPE_UTF8_ISSUE code from pyport.h: * Code added by commit b5047fd01948ab108edcc1b3c2c901d915814cfd in 2004 for MacOSX and FreeBSD. * Test removed by commit 52ddaefb6bab1a74ecffe8519c02735794ebfbe1 in 2007, since Python str type now uses locale independent functions like Py_ISALPHA() and Py_TOLOWER() and the Unicode database. Modules/_sre/sre.c replaces _PY_PORT_CTYPE_UTF8_ISSUE with new functions: sre_isalnum(), sre_tolower(), sre_toupper(). Remove unused includes: * _localemodule.c: remove <stdio.h>. * getargs.c: remove <float.h>. * dynload_win.c: remove <direct.h>, it no longer calls _getcwd() since commit fb1f68ed7cc1536482d1debd70a53c5442135fe2 (in 2001).

* bpo-43916: Add Py_TPFLAGS_DISALLOW_INSTANTIATION type flag (GH-25721)Victor Stinner2021-04-301-6/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a new Py_TPFLAGS_DISALLOW_INSTANTIATION type flag to disallow creating type instances: set tp_new to NULL and don't create the "__new__" key in the type dictionary. The flag is set automatically on static types if tp_base is NULL or &PyBaseObject_Type and tp_new is NULL. Use the flag on the following types: * _curses.ncurses_version type * _curses_panel.panel * _tkinter.Tcl_Obj * _tkinter.tkapp * _tkinter.tktimertoken * _xxsubinterpretersmodule.ChannelID * sys.flags type * sys.getwindowsversion() type * sys.version_info type Update MyStr example in the C API documentation to use Py_TPFLAGS_DISALLOW_INSTANTIATION. Add _PyStructSequence_InitType() function to create a structseq type with the Py_TPFLAGS_DISALLOW_INSTANTIATION flag set. type_new() calls _PyType_CheckConsistency() at exit.
