* gh-103865: add monitoring support to LOAD_SUPER_ATTR (#103866)Carl Meyer2023-05-161-1/+1
|
* gh-103763: Implement PEP 695 (#103764)Jelle Zijlstra2023-05-161-5/+5
| | | | | | | | | | | | | | This implements PEP 695, Type Parameter Syntax. It adds support for: - Generic functions (def func[T](): ...) - Generic classes (class X[T](): ...) - Type aliases (type X = ...) - New scoping when the new syntax is used within a class body - Compiler and interpreter changes to support the new syntax and scoping rules Co-authored-by: Marc Mueller <30130371+cdce8p@users.noreply.github.com> Co-authored-by: Eric Traut <eric@traut.com> Co-authored-by: Larry Hastings <larry@hastings.org> Co-authored-by: Alex Waygood <Alex.Waygood@Gmail.com>

|
* gh-87729: add LOAD_SUPER_ATTR instruction for faster super() (#103497)Carl Meyer2023-04-241-4/+4
| | | | | This speeds up `super()` (by around 85%, for a simple one-level `super().meth()` microbenchmark) by avoiding allocation of a new single-use `super()` object on each use.

| | | | | | | | | | (GH-103083) * The majority of the monitoring code is in instrumentation.c * The new instrumentation bytecodes are in bytecodes.c * legacy_tracing.c adapts the new API to the old sys.setrace and sys.setprofile APIs

* Revert "gh-100288: Specialise LOAD_ATTR_METHOD for managed dictionaries ↵Ken Jin2022-12-231-10/+10
| | | | | (GH-100289)" (#100468) This reverts commit c3c7848a48b74a321632202e4bdcf2f465fb1cc6.
