* gh-126491: Revert "GH-126491: Lower heap size limit with faster marking ↵Petr Viktorin2024-12-101-3/+66
| | | | | | | | (GH-127519)" (GH-127770) Revert "GH-126491: Lower heap size limit with faster marking (GH-127519)" This reverts commit 023b7d2141467017abc27de864f3f44677768cb3, which introduced a refleak.
* GH-126491: Lower heap size limit with faster marking (GH-127519)Mark Shannon2024-12-061-66/+3
| | | | | | | * Faster marking of reachable objects * Changes calculation of work to do and work done. * Merges transitive closure calculations
* gh-126091: Always link generator frames when propagating a thrown-in ↵Jacob Bower2024-11-211-6/+12
| | | | | exception through a yield-from chain (#126092) Always link generator frames when propagating a thrown-in exception through a yield-from chain.
* gh-111178: Fix function signatures in genobject.c (#124970)Victor Stinner2024-10-051-206/+271
| | | | | * Add "CAST" macros. * Rename parameters/variables "o" to "ag", "ags", "agw" or "agt" in some functions.
* gh-123923: Defer refcounting for `f_funcobj` in `_PyInterpreterFrame` (#124026)Sam Gross2024-09-241-4/+1
| | | | | | 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.
* gh-123923: Defer refcounting for `f_executable` in `_PyInterpreterFrame` ↵Sam Gross2024-09-121-4/+12
| | | | | | | | (#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-100240: Use a consistent implementation for freelists (#121934)Sam Gross2024-07-221-96/+12
| | | | | | | | This combines and updates our freelist handling to use a consistent implementation. Objects in the freelist are linked together using the first word of memory block. If configured with freelists disabled, these operations are essentially no-ops.
* gh-117139: Convert the evaluation stack to stack refs (#118450)Ken Jin2024-06-261-2/+2
| | | | | | | | | | | | | | | | | This PR sets up tagged pointers for CPython. The general idea is to create a separate struct _PyStackRef for everything on the evaluation stack to store the bits. This forces the C compiler to warn us if we try to cast things or pull things out of the struct directly. Only for free threading: We tag the low bit if something is deferred - that means we skip incref and decref operations on it. This behavior may change in the future if Mark's plans to defer all objects in the interpreter loop pans out. This implies a strict stack reference discipline is required. ALL incref and decref operations on stackrefs must use the stackref variants. It is unsafe to untag something then do normal incref/decref ops on it. The new incref and decref variants are called dup and close. They mimic a "handle" API operating on these stackrefs. Please read Include/internal/pycore_stackref.h for more information! --------- Co-authored-by: Mark Shannon <9448417+markshannon@users.noreply.github.com>
