* [3.13] gh-118846: Fix PGO tests in free-threaded build (GH-118862) (#118867)Miss Islington (bot)2024-05-092-2/+4
| | | | | | | | | Avoid immortalizing objects in tests that verify garbage collection of classes or modules. This fixes test_ordered_dict and test_struct. (cherry picked from commit 1b1db2fd9a531e26b79b34667bccfb938c4d184d) Co-authored-by: Sam Gross <colesbury@gmail.com>
* [3.13] gh-116984: Make mimalloc header includes relative to the current file ↵Miss Islington (bot)2024-05-094-6/+9
| | | | | | | | | | | (GH-118808) (#118866) Some embedders and extensions include parts of the internal API. The pycore_mimalloc.h file is transitively include by a number of other internal headers. This avoids include errors for code that was already including those headers. (cherry picked from commit 71cc0651e79041abd648595f3030dfa41009137a) Co-authored-by: Sam Gross <colesbury@gmail.com>
* [3.13] gh-118561: Fix crash involving list.extend in free-threaded build ↵Miss Islington (bot)2024-05-092-1/+4
| | | | | | | | | | | | (GH-118723) (#118863) The `list_preallocate_exact` function did not zero initialize array contents. In the free-threaded build, this could expose uninitialized memory to concurrent readers between the call to `list_preallocate_exact` and the filling of the array contents with items.

* gh-118610: Centralize power caching in `_pylong.py` (#118611)Tim Peters2024-05-082-67/+113
| | | | | A new `compute_powers()` function computes all and only the powers of the base the various base-conversion functions need, as efficiently as reasonably possible (turns out that invoking `**`is needed at most once). This typically gives a few % speedup, but the primary point is to simplify the base-conversion functions, which no longer need their own, ad hoc, and less efficient power-caching schemes.

| | | | | | | | | 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.
