As explained in #133960, this removes most of the behavior differences with ForwardRef.evaluate. The remaining difference is about recursive evaluation of forwardrefs; this is practically useful in cases where an annotation refers to a type alias that itself is string-valued. This also improves several edge cases that were previously not handled optimally. For example, the function now takes advantage of the partial evaluation behavior of ForwardRef.evaluate() to evaluate more ForwardRefs in the FORWARDREF format. This also fixes #133959 as a side effect, because the buggy behavior in #133959 derives from evaluate_forward_ref().
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 <[email protected]>
