* gh-105035: fix super() calls on unusual types (e.g. meta-types) (#105094)Carl Meyer2023-05-301-1/+3
|
* GH-104580: Don't cache eval breaker in interpreter (GH-104581)Mark Shannon2023-05-181-3/+2
| | | Move eval-breaker to the front of the interpreter state.
* GH-103906: Remove immortal refcounting in the interpreter (GH-103909)Brandt Bucher2023-05-161-32/+14
|
* gh-103865: add monitoring support to LOAD_SUPER_ATTR (#103866)Carl Meyer2023-05-161-0/+32
|
* gh-103763: Implement PEP 695 (#103764)Jelle Zijlstra2023-05-161-17/+36
| | | | | | | | | | | | | | 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-104405: Add missing PEP 523 checks (GH-104406)Brandt Bucher2023-05-121-2/+6
|
* GH-103082: Filter LINE events in VM, to simplify tool implementation. ↵Mark Shannon2023-05-121-22/+0
| | | | | | | | (GH-104387) When monitoring LINE events, instrument all instructions that can have a predecessor on a different line. Then check that the a new line has been hit in the instrumentation code. This brings the behavior closer to that of 3.11, simplifying implementation and porting of tools.
* gh-104413: Fix refleak when super attribute throws AttributeError (#104414)Jelle Zijlstra2023-05-121-1/+1
|
* gh-87729: improve hit rate of LOAD_SUPER_ATTR specialization (#104270)Carl Meyer2023-05-111-9/+31
|

* gh-97933: (PEP 709) inline list/dict/set comprehensions (#101441)Carl Meyer2023-05-091-0/+6
| | | | Co-authored-by: Irit Katriel <1055913+iritkatriel@users.noreply.github.com> Co-authored-by: Erlend E. Aasland <erlend.aasland@protonmail.com>

|
* gh-87729: specialize LOAD_SUPER_ATTR_METHOD (#103809)Carl Meyer2023-04-251-26/+39
|
* gh-87729: add LOAD_SUPER_ATTR instruction for faster super() (#103497)Carl Meyer2023-04-241-0/+31
| | | | | 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-103488: Use return-offset, not yield-offset. (GH-103502)Mark Shannon2023-04-131-10/+18
| | | | * Use return-offset, not yield-offset, so that instruction pointer is correct when sending to a generator or coroutine.
* GH-103082: Implementation of PEP 669: Low Impact Monitoring for CPython ↵Mark Shannon2023-04-121-95/+347
| | | | | | | | | | (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
* GH-88691: Shrink the CALL caches (GH-103230)Brandt Bucher2023-04-051-19/+24
|
* gh-102192: use PyErr_SetHandledException instead of the legacy ↵Irit Katriel2023-04-011-1/+1
| | | | PyErr_SetExcInfo (#103157)
* Add missing variables to `bytecodes.c` (GH-103153)Brett Cannon2023-03-311-1/+47
| | | The code works without this change, but it does cause C tooling to complain less about undeclared variables.

* GH-101291: Rearrange the size bits in PyLongObject (GH-102464)Mark Shannon2023-03-221-10/+9
| | | | | | | | | | * Eliminate all remaining uses of Py_SIZE and Py_SET_SIZE on PyLongObject, adding asserts. * Change layout of size/sign bits in longobject to support future addition of immortal ints and tagged medium ints. * Add functions to hide some internals of long object, and for setting sign and digit count. * Replace uses of IS_MEDIUM_VALUE macro with _PyLong_IsCompact().

| | | | | | | `_PyEval_EvalFrameDefault`. (#102640) * Rename local variables, names and consts, from the interpeter loop. Will allow non-code objects in frames for better introspection of C builtins and extensions. * Remove unused dummy variables.
* GH-102300: Reuse objects with refcount == 1 in float specialized binary ops. ↵Mark Shannon2023-03-131-12/+3
