* [3.14] gh-136421: Load `_datetime` static types during interpreter ↵Miss Islington (bot)2025-07-211-0/+1
| | | | | | | | | | initialization (GH-136583) (GH-136943) gh-136421: Load `_datetime` static types during interpreter initialization (GH-136583) `_datetime` is a special module, because it's the only non-builtin C extension that contains static types. As such, it would initialize static types in the module's execution function, which can run concurrently. Since static type initialization is not thread-safe, this caused crashes. This fixes it by moving the initialization of `_datetime`'s static types to interpreter startup (where all other static types are initialized), which is already properly protected through other locks.

* [3.14] GH-133136: Revise QSBR to reduce excess memory held (gh-135473) (#135912)Miss Islington (bot)2025-07-082-7/+26
| | | | | | | | | | | | | | | | | | | | The free threading build uses QSBR to delay the freeing of dictionary keys and list arrays when the objects are accessed by multiple threads in order to allow concurrent reads to proceed with holding the object lock. The requests are processed in batches to reduce execution overhead, but for large memory blocks this can lead to excess memory usage. Take into account the size of the memory block when deciding when to process QSBR requests. Also track the amount of memory being held by QSBR for mimalloc pages. Advance the write sequence if this memory exceeds a limit. Advancing the sequence will allow it to be freed more quickly. Process the held QSBR items from the "eval breaker", rather than from `_PyMem_FreeDelayed()`. This gives a higher chance that the global read sequence has advanced enough so that items can be freed.

* [3.14] gh-135443: Sometimes Fall Back to __main__.__dict__ For Globals ↵Miss Islington (bot)2025-06-161-0/+10
| | | | | | | | | | | | | | | | | | | | | | | (gh-135593) For several builtin functions, we now fall back to __main__.__dict__ for the globals when there is no current frame and _PyInterpreterState_IsRunningMain() returns true. This allows those functions to be run with Interpreter.call(). The affected builtins: * exec() * eval() * globals() * locals() * vars() * dir() We take a similar approach with "stateless" functions, which don't use any global variables.

* [3.14] gh-91048: Refactor and optimize remote debugging module (#134652) ↵Pablo Galindo Salgado2025-05-257-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | (#134673) gh-91048: Refactor and optimize remote debugging module (#134652) Completely refactor Modules/_remote_debugging_module.c with improved code organization, replacing scattered reference counting and error handling with centralized goto error paths. This cleanup improves maintainability and reduces code duplication throughout the module while preserving the same external API. Implement memory page caching optimization in Python/remote_debug.h to avoid repeated reads of the same memory regions during debugging operations. The cache stores previously read memory pages and reuses them for subsequent reads, significantly reducing system calls and improving performance. Add code object caching mechanism with a new code_object_generation field in the interpreter state that tracks when code object caches need invalidation. This allows efficient reuse of parsed code object metadata and eliminates redundant processing of the same code objects across debugging sessions. Optimize memory operations by replacing multiple individual structure copies with single bulk reads for the same data structures. This reduces the number of memory operations and system calls required to gather debugging information from the target process. Update Makefile.pre.in to include Python/remote_debug.h in the headers list, ensuring that changes to the remote debugging header force proper recompilation of dependent modules and maintain build consistency across the codebase. Also, make the module compatible with the free threading build as an extra :) Co-authored-by: Łukasz Langa <lukasz@langa.pl> (cherry picked from commit 42b25ad4d3d6bcdc28ddfe07d2bf8831378bb0d1)
