Irit Katriel 665a4391e1 gh-105481: generate op IDs from bytecode.c instead of hard coding them in opcode.py (#107971) 2023-08-16 22:25:18 +00:00
Anders Kaseorg 557b05c7a5 gh-106092: Fix use-after-free crash in frame_dealloc (#106875)
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.

Mark Shannon 7199584ac8 GH-100987: Allow objects other than code objects as the "executable" of an internal frame. (GH-105727)
* Add table describing possible executable classes for out-of-process debuggers.

* Remove shim code object creation code as it is no longer needed.

Mark Shannon 45f5aa8fc7 GH-103082: Filter LINE events in VM, to simplify tool implementation. (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.
