Mark Shannon 9eab67d507 GH-138245: Perform boolean guards by testing a single bit, rather than a full pointer comparison. (GH-143810) 2026-01-21 15:58:27 +00:00
AN Long 54bedcf714 gh-144012: Check null binary op extend (#144014) 2026-01-19 02:38:37 +08:00
Mark Shannon ae53da5758 GH-143493: Conform to spec for generator expressions while supporting virtual iterators (GH-143569) 
* Moves the `GET_ITER` instruction into the generator function preamble.
  This means the the iterable is converted into an iterator during generator
  creation, as documented, but keeps it in the same code object allowing
  optimization.

Sam Gross 08bc03ff2a gh-120321: Make gi_frame_state transitions atomic in FT build (gh-142599) 
This makes generator frame state transitions atomic in the free
threading build, which avoids segfaults when trying to execute
a generator from multiple threads concurrently.

There are still a few operations that aren't thread-safe and may crash
if performed concurrently on the same generator/coroutine:

 * Accessing gi_yieldfrom/cr_await/ag_await
 * Accessing gi_frame/cr_frame/ag_frame
 * Async generator operations
