Issues

• docs: stale numbers in pyre/design.md and pyre/rework.md (re-measured 2026-11-12)

• env switches that select semantics rather than diagnostics

  pyre-lang/pyre#2669 · Filter by author youknowone opened on Nov 11, 2026

• modules: small surface mismatches — _sre.OPCODES, _string placement, itertools._groupby, sys identity

  pyre-lang/pyre#2668 · Filter by author youknowone opened on Nov 11, 2026

• modules: _tracemalloc / _sysconfig are name-only stubs, and several builtin modules have no PyPy owner — needs an owner ruling

  pyre-lang/pyre#2667 · Filter by author youknowone opened on Nov 11, 2026

• modules: pypyjit exports only set_param, __pypy__ has about 15 of 50 names, and submodules are not bound on the parent

  pyre-lang/pyre#2666 · Filter by author youknowone opened on Nov 11, 2026

• space: fromcache is a closed two-variant enum — MethodCache, MapAttrCache, module State and the builtin-module table are statics

  pyre-lang/pyre#2665 · Filter by author youknowone opened on Nov 11, 2026

• backend: llsupport duties are written once per backend; AbstractLLCPU is reduced to free functions

  pyre-lang/pyre#2664 · Filter by author youknowone opened on Nov 11, 2026

• gc: port TypeLayoutBuilder — 93 hand register_type sites assign type ids by registration order

  pyre-lang/pyre#2663 · Filter by author youknowone opened on Nov 11, 2026

• gc: decide how the native interpreter is rooted — hand brackets, born-old allocation and extra root walkers all wait on it

  pyre-lang/pyre#2662 · Filter by author youknowone opened on Nov 11, 2026

• metainterp: port CompileData.optimize as four methods; move compile_loop / compile_trace / compile_retrace out of MetaInterp

  pyre-lang/pyre#2661 · Filter by author youknowone opened on Nov 11, 2026

• metainterp: route every descr mint through gc_cache.get_*_descr

  pyre-lang/pyre#2660 · Filter by author youknowone opened on Nov 11, 2026

• metainterp: one Trace recorder, then one box identity (OpRef vs Operand)

  pyre-lang/pyre#2659 · Filter by author youknowone opened on Nov 11, 2026

• gateway: BuiltinCode0..4 are empty shells, applevel() returns null, and app-level helpers are rewritten in Rust

  pyre-lang/pyre#2658 · Filter by author youknowone opened on Nov 11, 2026

• walker: callee recognition outside the spec_folds! census (RuntimeHelperKind, try_walker_fold_*, try_emit_exact_int_binop)

  pyre-lang/pyre#2657 · Filter by author youknowone opened on Nov 11, 2026

• objspace: port the nested JitDrivers — 3 of 22 exist

  pyre-lang/pyre#2656 · Filter by author youknowone opened on Nov 11, 2026

• mapdict: find_map_attr and _get_new_attr are not elidable

  pyre-lang/pyre#2655 · Filter by author youknowone opened on Nov 11, 2026

• objspace: 750 dont_look_inside attributes against upstream's 9 — hint-parity sweep

  pyre-lang/pyre#2654 · Filter by author youknowone opened on Nov 11, 2026

• jit: seven opcodes still abort the trace permanently

  pyre-lang/pyre#2653 · Filter by author youknowone opened on Nov 11, 2026

• jit: one resume decoder and one _run_forever — retire the bridge recipe decoder and the hand-inlined blackhole loop

  pyre-lang/pyre#2652 · Filter by author youknowone opened on Nov 11, 2026

• warmspot: port the apply_jit graph rewrites — task_pyjitpl_lltype still returns TaskError

  pyre-lang/pyre#2651 · Filter by author youknowone opened on Nov 11, 2026

• jit: production traces through the walker and a runtime codewriter, not MIFrame over the interpreter's jitcode

  pyre-lang/pyre#2650 · Filter by author youknowone opened on Nov 11, 2026

• translator: path-keyed side tables and thread_local registries where upstream stores on the graph, class or lltype

  pyre-lang/pyre#2649 · Filter by author youknowone opened on Nov 11, 2026

• translator: port exceptiontransform.py as a post-rtyper pass

  pyre-lang/pyre#2648 · Filter by author youknowone opened on Nov 11, 2026

• translator: move the front-end recognisers to their rtyper / extregistry / simplify owners

  pyre-lang/pyre#2647 · Filter by author youknowone opened on Nov 11, 2026

• translator: jtransform reads front-lowered OpKind graphs — the rtyper's lowered operations are discarded even on Match'd graphs
