Sam Gross	4dc27bc0b7	[3.13] gh-119344: Make critical section API public (GH-119353) (#120856) ... This makes the following macros public as part of the non-limited C-API for locking a single object or two objects at once. * `Py_BEGIN_CRITICAL_SECTION(op)` / `Py_END_CRITICAL_SECTION()` * `Py_BEGIN_CRITICAL_SECTION2(a, b)` / `Py_END_CRITICAL_SECTION2()` The supporting functions and structs used by the macros are also exposed for cases where C macros are not available.

Sam Gross	31c90d5838	gh-111569: Implement Python critical section API (gh-111571) ... Critical sections are helpers to replace the global interpreter lock with finer grained locking. They provide similar guarantees to the GIL and avoid the deadlock risk that plain locking involves. Critical sections are implicitly ended whenever the GIL would be released. They are resumed when the GIL would be acquired. Nested critical sections behave as if the sections were interleaved.	2023-11-08 15:39:29 -07:00
