* [3.13] gh-74929: PEP 667 C API documentation (gh-119892)Miss Islington (bot)2024-06-011-2/+7
| | | | | | | | | | | * Add docs for new APIs * Add soft-deprecation notices * Add What's New porting entries * Update comments referencing `PyFrame_LocalsToFast()` to mention the proxy instead * Other related cleanups found when looking for refs to the deprecated APIs (cherry picked from commit 3859e09e3d92d004978dd838f0511364e7edfb94) Co-authored-by: Alyssa Coghlan <ncoghlan@gmail.com>
* [3.13] gh-118921: Add `copy()` method for `FrameLocalsProxy` (GH-118923) ↵Miss Islington (bot)2024-05-101-0/+19
| | | | | | | (#118933) (cherry picked from commit 35c436186b849f8f2f9fb866c59015c9d034d448) Co-authored-by: Tian Gao <gaogaotiantian@hotmail.com>
* gh-118746: Fix crash in frame_getlocals and _PyFrame_GetLocals (#118748)Tian Gao2024-05-081-0/+18
| | | | We don't know how to create an unoptimized frame with f_locals == NULL, but they are seen in the wild, and this fixes the crash.

* gh-106092: Fix use-after-free crash in frame_dealloc (#106875)Anders Kaseorg2023-08-011-6/+7
| | | | | | | | | It was possible for the trashcan to delay the deallocation of a PyFrameObject until after its corresponding _PyInterpreterFrame has already been freed. So frame_dealloc needs to avoid dereferencing the f_frame pointer unless it first checks that the pointer still points to the interpreter frame within the frame object.

* GH-103082: Filter LINE events in VM, to simplify tool implementation. ↵Mark Shannon2023-05-121-3/+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.
