Use clang 18 in TSAN builds We were using clang 14 which is a couple of years old.
…mode (pythonGH-118320) Fix an edge case in `binascii.a2b_base64` strict mode, where excessive padding was not detected when no padding is necessary. Co-authored-by: Terry Jan Reedy <[email protected]> Co-authored-by: Pieter Eendebak <[email protected]>

…118311) The provided example was incorrect: - The example enum was missing the `int` mixin as implied by the context - The value of `int('1a', 16)` was incorrectly given as 17 (should be 26)

…nGH-98592) 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.

…118711) Make a rough editorial pass over Python 3.13's What's New document. Add the release highlights, remove or merge some duplicated entries, and reorder some of the sections (removals should really go before future deprecations).
) 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.

…path()` (python#118489) Co-authored-by: Nice Zombies <[email protected]>
Asymptotically faster (O(n log n)) str->int for very large strings, leveraging the faster multiplication scheme in the C-coded `_decimal` when available. This is used instead of the current Karatsuba-limited method starting at 2 million digits. Lots of opportunity remains for fine-tuning. Good targets include changing BYTELIM, and possibly changing the internal output base (from 256 to a higher number of bytes). Doing this was substantial work, and many of the new lines are actually comments giving correctness proofs. The obvious approaches sticking to integers were too slow to be useful, so this is doing variable-precision decimal floating-point arithmetic. Much faster, but worst-possible rounding errors have to be wholly accounted for, using as little precision as possible. Special thanks to Serhiy Storchaka for asking many good questions in his code reviews!

Various test bots (outside the ones GH normally runs) are timing out during test_int after ecd8664 (asymptotically faster str->int). Best guess is that they don't build the C _decimal module. So require that module in the most likely tests to time out then. Flying mostly blind, though!
Nobody has been using a Sun machine for a long time. When I saw this sentence in a lightning talk just now, I thought it was talking about sending Python code on a spacecraft.
