* Align compiler and VM with final CPython 3.15 bytecode Reconstruct the compiler-only baseline from validated487ae47 on the current main and frozen mapping prerequisitec78d811. Preserve the full source delta while dropping obsolete prerequisite ancestry; detailed old-to-new provenance is retained in the recovery artifact. Assisted-by: OpenAI Codex: model identifier unavailable * Fix final script validation, exception cleanup and private cache contracts Replay reviewed compiler CI repairs 2191a9d, 1f1fe04, a2dacaf on the frozen current prerequisite. Intermediate compile/diagnostic corrections are combined where they address the same failure. Assisted-by: OpenAI Codex: model identifier unavailable * Align canonical compiler fixtures and generator frame state Replay reviewed compiler CI repairs 476bb74 on the frozen current prerequisite. Intermediate compile/diagnostic corrections are combined where they address the same failure. Assisted-by: OpenAI Codex: model identifier unavailable * Preserve code-name owners and final warning and constant-fold contracts Replay reviewed compiler CI repairs 6482adf on the frozen current prerequisite. Intermediate compile/diagnostic corrections are combined where they address the same failure. Assisted-by: OpenAI Codex: model identifier unavailable * Skip unavailable monitoring C API tests before tool registration Replay reviewed compiler CI repairs 246c309 on the frozen current prerequisite. Intermediate compile/diagnostic corrections are combined where they address the same failure. Assisted-by: OpenAI Codex: model identifier unavailable * Assert exact final constant-list iterable folding Replay reviewed compiler CI repairs 7ecedcf on the frozen current prerequisite. Intermediate compile/diagnostic corrections are combined where they address the same failure. Assisted-by: OpenAI Codex: model identifier unavailable * Align local monitoring events and exception lifecycle state with final 3.15 Replay reviewed compiler CI repairs ec206b1, 191fe58 on the frozen current prerequisite. Intermediate compile/diagnostic corrections are combined where they address the same failure. Assisted-by: OpenAI Codex: model identifier unavailable * Align 3.15 code objects and codegen with CPython - Store co_consts, co_names, co_localsplusnames, co_localspluskinds, co_linetable, co_exceptiontable and co_name as objects on PyCode; build co_code and the varnames/cellvars/freevars tuples lazily in _co_cached, with co_code deoptimized through deopt_code. - Move the compiler constant cache (_PyCode_ConstantKey, const_cache_insert) to builtins/code/const_cache.rs. - Write every code field with w_object in marshal and pass the read field objects to MarshalBag::make_code through CodeFields. - Emit RETURN_GENERATOR/POP_TOP in enter_scope and place SETUP_CLEANUP after them; drop the generator part of insert_prefix_instructions. - Add PyCode::first_traceable (_co_firsttraceable) for _PyFrame_IsIncomplete and sys.monitoring. - Follow the CPython DISABLE branches in sys.monitoring, the check_matched signature in warnings, the 3.15 % format error messages for str and bytes, code_returns_only_none, and the FOR_ITER stack analysis. - Compute IMPORT_NAME flags with in_exception_handler. - Replace the linetable/exceptiontable byte tests in codegen with dis(show_positions=True) insta snapshots in _opcode. - Remove the opcode metadata verification tooling, byte-exact scripts, private cache tests and redundant snippets. - Restore test_code.py and test_monitoring.py to v3.15.0 plus RUSTPYTHON markers. Assisted-by: Claude Code:claude-opus-5-5 * Remove generator snippet checks covered by Lib/test Drop extra_tests/snippets/generator_iterator_prefix.py. Its loop, delegation, async, f_back and never-awaited checks are covered by test_generators, test_coroutines, test_asyncgen, test_yield_from and test_monitoring. Move the remaining checks into existing files: genexpr prefix tracing and monitoring into stdlib_sys.py, and the caller frame seen from the eager iterator into stdlib_sys_getframe.py. Assisted-by: Claude Code:claude-opus-5-5 * Emit the generator prefix for top-level await modules Module code compiled with PyCF_ALLOW_TOP_LEVEL_AWAIT and marked ste_coroutine now starts with RETURN_GENERATOR; POP_TOP. The prefix and RESUME emission move into emit_scope_prefix, shared by enter_scope and the module entry points, as in codegen_enter_scope. Fixes test_builtin.test_compile_top_level_await. Assisted-by: Claude Code:claude-opus-5-5 * Allow the c_long cast in _opcode.stack_effect c_long is i32 on Windows, where clippy reports the cast to i32 as unnecessary. Assisted-by: Claude Code:claude-opus-5-5 * Update malachite crates to 0.14.0 pymath requires malachite-bigint ^0, so the example projects, which have no lock file, resolve it to 0.14.0 while the workspace pinned 0.13.0, and fail to build.
