* GH-114847: Speed up `posixpath.realpath()` (#114848)Barney Gale2024-04-053-34/+64
| | | | | | | | | | | Apply the following optimizations to `posixpath.realpath()`: - Remove use of recursion - Construct child paths directly rather than using `join()` - Use `os.getcwd[b]()` rather than `abspath()` - Use `startswith(sep)` rather than `isabs()` - Use slicing rather than `split()` Co-authored-by: Petr Viktorin <encukou@gmail.com>

* gh-117474: Skip GIL test in free-threaded build (#117475)Sam Gross2024-04-041-0/+1
| | | | In the free-threaded build, the GIL will typically be disabled so `py-bt` will not show threads waiting on the GIL.

* gh-116968: Reimplement Tier 2 counters (#117144)Guido van Rossum2024-04-0419-235/+313
| | | | | | | | | | | | Introduce a unified 16-bit backoff counter type (``_Py_BackoffCounter``), shared between the Tier 1 adaptive specializer and the Tier 2 optimizer. The API used for adaptive specialization counters is changed but the behavior is (supposed to be) identical. The behavior of the Tier 2 counters is changed: - There are no longer dynamic thresholds (we never varied these). - All counters now use the same exponential backoff. - The counter for ``JUMP_BACKWARD`` starts counting down from 16. - The ``temperature`` in side exits starts counting down from 64.

* gh-116168: Remove extra `_CHECK_STACK_SPACE` uops (#117242)Peter Lazorchak2024-04-038-126/+494
| | | This merges all `_CHECK_STACK_SPACE` uops in a trace into a single `_CHECK_STACK_SPACE_OPERAND` uop that checks whether there is enough stack space for all calls included in the entire trace.
* gh-76785: Raise InterpreterError, Not RuntimeError (gh-117489)Eric Snow2024-04-038-23/+40
| | | | | I had meant to switch everything to InterpreterError when I added it a while back. At the time I missed a few key spots. As part of this, I've added print-the-exception to _PyXI_InitTypes() and fixed an error case in `_PyStaticType_InitBuiltin().
