* gh-124296: Remove private dictionary version tag (PEP 699) (#124472)Sam Gross2024-10-011-3/+1

* GH-123516: Improve JIT memory consumption by invalidating cold executors ↵Savannah Ostrowski2024-09-271-0/+8
| | | | | (GH-124443) Co-authored-by: Bénédikt Tran <10796600+picnixz@users.noreply.github.com>
* gh-117376: Fix off-by-ones in conversion functions (GH-124301)Ken Jin2024-09-251-2/+2
| | | Fix off-by-ones in conversion function
* gh-124285: Fix bug where bool() is called multiple times for the same part ↵Irit Katriel2024-09-251-0/+8
| | | | of a boolean expression (#124394)
* gh-123923: Defer refcounting for `f_funcobj` in `_PyInterpreterFrame` (#124026)Sam Gross2024-09-241-24/+21
| | | | | | Use a `_PyStackRef` and defer the reference to `f_funcobj` when possible. This avoids some reference count contention in the common case of executing the same code object from multiple threads concurrently in the free-threaded build.

| | | | | | | | (#123924) Use a `_PyStackRef` and defer the reference to `f_executable` when possible. This avoids some reference count contention in the common case of executing the same code object from multiple threads concurrently in the free-threaded build.
* GH-123996: Explicitly mark 'self_or_null' as an array of size 1 to ensure ↵Mark Shannon2024-09-121-76/+67

| | | | Use _Py_IsImmortalLoose() in bytesobject.c, typeobject.c and ceval.c.
* GH-123232: Factor BINARY_SLICE and STORE_SLICE to handle stats properly for ↵Mark Shannon2024-08-271-4/+20
| | | | tier 2. (GH-123381)

| | | | (gh-123092)
* GH-123197: Only count an instruction as deferred if it hasn't deopted first. ↵Mark Shannon2024-08-221-15/+15
| | | | | (GH-123222) Only count an instruction as deferred if hasn't deopted first.
* GH-115776: Allow any fixed sized object to have inline values (GH-123192)Mark Shannon2024-08-211-7/+9
|
* GH-123197: Increment correct stat for CALL_KW (GH-123200)Mark Shannon2024-08-211-1/+1
|
* GH-123185: Check for `NULL` after calling `_PyEvalFramePushAndInit` (GH-123194)Mark Shannon2024-08-211-1/+5
|
* GH-118093: Make `CALL_ALLOC_AND_ENTER_INIT` suitable for tier 2. (GH-123140)Mark Shannon2024-08-201-42/+39
| | | | | * Convert CALL_ALLOC_AND_ENTER_INIT to micro-ops such that tier 2 supports it * Allow inexact arguments for CALL_ALLOC_AND_ENTER_INIT.

|
* GH-120024: Remove `CHECK_EVAL_BREAKER` macro. (GH-122968)Mark Shannon2024-08-141-57/+76

* GH-118093: Handle some polymorphism before requiring progress in tier two ↵Brandt Bucher2024-08-121-3/+4
| | | | (GH-122843)
* gh-117139: Replace _PyList_FromArraySteal with stack ref variant (#122830)Sam Gross2024-08-121-7/+1
| | | | | | | This replaces `_PyList_FromArraySteal` with `_PyList_FromStackRefSteal`. It's functionally equivalent, but takes a `_PyStackRef` array instead of an array of `PyObject` pointers. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-117139: Fix a few `_PyStackRef` related bugs (#122831)Sam Gross2024-08-121-4/+6
| | | | | | `BUILD_SET` should use a borrow instead of a steal. The cleanup in `_DO_CALL` `CONVERSION_FAILED` was incorrect. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-118926: Spill deferred references to stack in cases generator (#122748)Sam Gross2024-08-071-1/+1
| | | | | | | This automatically spills the results from `_PyStackRef_FromPyObjectNew` to the in-memory stack so that the deferred references are visible to the GC before we make any possibly escaping call. Co-authored-by: Ken Jin <kenjin@python.org>
* gh-122759: Remove `assert` from `RERAISE` error handling (#122760)sobolevn2024-08-071-1/+0
|
* gh-117139: Fix an incorrect borrow in bytecodes.c (#122318)Sam Gross2024-08-071-3/+4
| | | `_PyDict_SetItem_Take2` steals both the key (i.e., `sub`) and the value.
* GH-120024: Move three more escaping calls out of conditional statements ↵Mark Shannon2024-08-061-4/+12

* GH-122029: Break INSTRUMENTED_CALL into micro-ops, so that its behavior is ↵Mark Shannon2024-07-261-29/+42
| | | | consistent with CALL (GH-122177)
* GH-121131: Clean up and fix some instrumented instructions. (GH-121132)Mark Shannon2024-07-261-58/+57
| | | | * Add support for 'prev_instr' to code generator and refactor some INSTRUMENTED instructions

* GH-121784: Generate an error during code gen if a variable is marked ↵Mark Shannon2024-07-181-10/+7
| | | | | | | | | | | | `unused`, but is used and thus cached in a prior uop. (#121788) * Reject uop definitions that declare values as 'unused' that are already cached by prior uops * Track which variables are defined and only load from memory when needed * Support explicit `flush` in macro definitions. * Make sure stack is flushed in where needed.
* GH-121012: Set index to -1 when list iterators become exhausted in tier 2 ↵Mark Shannon2024-07-081-1/+4
