…racebacks. This is part 1 of issue python#107. If you unpickle a traceback object, Stackless now reconstructs the f_back links of the assorted frame objects. There is also a new test case in test_pickle.py. Manually grafted from pull request python#22. https://bitbucket.org/stackless-dev/stackless/issues/107 (grafted from 3719f4e0d4371b941777f423941bfe5e875f9cf6)

…le stackless This is part 2 of issue python#107. Fist step. Move the registration code for Stackless specific reduce functions into the module stackless. This simplifies the C code quite a bit. This commit does not modify the behaviour of Stackless once the module stackless has been loaded. https://bitbucket.org/stackless-dev/stackless/issues/107

This is part 2 of issue python#107. Second step. Stackless no longer pretends to be able to pickle frame objects in general. It still pickles frames as part of tasklets or traceback objects. This way Stackless adheres closely to the pickling protocol. https://bitbucket.org/stackless-dev/stackless/issues/107

…tor and traceback objects __setstate__ must accept the state returned by __reduce__. This was not the case for generator and trace-back objects. This commit fixes this. The next commit (merge of issue python#127) adds the relevant test cases. Additionally amends changelog.txt. https://bitbucket.org/stackless-dev/stackless/issues/107

Per docs/tier8-class-b-cport-migrate-arm-spec.md theologian 01:01:50Z + supervisor 01:02:46Z ADOPTED + supervisor 01:18:35Z + 03:44:19Z + 04:14:27Z (8-incident root-cause attribution to §3.5 restore-trap + b83f084 fix LIVE). Migrates HIRBuilder std::vector<ExceptionTableEntry> exception_table_ field to PhxExceptionTable (purpose-built typed-inline pure-C container in PhxHirBuilderState.exception_table_phx). Validates Pythia python#103 + python#94 (3) §5 forcing-decision MIGRATE-ARM via 1-pilot port (vs Phase 3's 4-Class-B-kept disposition). CONTAINER: PhxExceptionTable (builder_state_c.h): typed-inline data/count/capacity with 6 inline funcs (init/destroy/push/size/at/clear). Lazy-init, doubling realloc, free at HIRBuilder dtor. ExceptionTableEntry (builder_state_c.h): POD mirror of deleted C++ struct, fields flattened BCOffset → int + bool → unsigned char. C BODY PORTS (builder_state_c.c): hir_builder_state_init: also calls phx_exception_table_init hir_builder_state_destroy: NEW (calls phx_exception_table_destroy) parse_exception_table_c: pushes ExceptionTableEntry via phx_exception_table_push (replaces deleted push_cpp bridge) find_exception_handler_c: linear scan via phx_exception_table_size + at (replaces deleted size_cpp/entry_cpp bridges) C++ SHIM (transient compatibility per Phase A; Phase B deletes): HIRBuilder::parseExceptionTable → 1-line delegate to C body HIRBuilder::findExceptionHandler → C body returns index, shim converts via phx_exception_table_at preserving caller-contract HIRBuilder::buildHIRImpl translate-loop iterates PhxExceptionTable via size+at; .clear() goes to phx_exception_table_clear HIRBuilder::getSimpleExceptInfo wraps handler.target in BCOffset{} (now plain int post-C struct migration) emit_call_method_exception_handler_inline_c at builder.cpp:2883 still calls self->findExceptionHandler (KEPT shim — Phase B will rewire) DELETED: 3 _cpp bridge impls in builder.cpp (push/size/entry, ~37L) 3 friend decls in builder.h C++ struct ExceptionTableEntry in builder.h (5L) std::vector<ExceptionTableEntry> exception_table_ field in builder.h W45 §1-§2 fixture removals (3): the deleted bridges no longer have signatures to fuzz. Cumulative bridge-count delta: -3 (per Tier 8 spec §5 python#11 acceptance). Numstat (vs HEAD b83f084): Python/jit/hir/builder.cpp +21 -44 (-23 NET) Python/jit/hir/builder.h +14 -19 (-5 NET) Python/jit/hir/builder_state_c.c +30 -17 (+13 NET) Python/jit/hir/builder_state_c.h +103 -48 (+55 NET) scripts/w45_bridge_drift_falsifier.sh +0 -3 (-3 NET) TOTAL: NET +37L, bridge-count delta -3. Per Tier 8 spec §5 python#10 amendment (theologian 01:14:29Z): full Tier 8 endpoint ≤+0L cumulative is across all 4 Class B containers, not single pilot. exception_table_ pilot subtracts ~19% of Phase 3 +257L foundation cost; Phase 3 + Tier 8 Phase A cumulative now +257 + 37 = +294L. Apply mechanism: python single-process write (8-incident root cause was §3.5 restore-trap, NOT Write-tool-burst — but python single-process remains best practice per Pythia python#107 (4) isolation principle). Apply script: /tmp/apply_phase_a.py. EXPANDED PRE-COMMIT GATE per supervisor 01:17:23Z (testkeeper 04:24:49Z): Stage 1 compile-check: BUILD_EXIT=0 Stage 2 §3.5 BUILD MODE: 4/4 PASS, PhxExceptionTable INTACT post (§3.5 fix b83f084 VINDICATED) Stage 3 per-bench gate: GEO 1.27x, all 4 floor criteria PASS §5 forcing-decision MIGRATE-ARM EMPIRICALLY VALIDATED via this pilot: exception_table_ migrated to PhxArray-equivalent pure-C container without C++-side-keep dependency in C-side reads. Pattern propagatable to remaining 3 Class B containers (block_map_, temps_, static_method_stack_) in future Tier 8 batches per spec §1.1 container-shape transferability caveat. Phase B follow-up commit (NEXT) deletes C++ shims + rewires the remaining caller at builder.cpp:2883 per Tier 8 spec §5 python#5. Authorization: supervisor 03:44:19Z + 04:14:27Z; theologian 03:33:50Z patch-apply hybrid + 03:54:15Z content-trigger refinement (later attributed to §3.5 trap, not content) + 04:14:27Z fix directive. Cross-link: 8 incidents resolved via b83f084 §3.5 restore-trap fix. Pythia python#105 'fever has name infection still spreads' RESOLVED — fever was self-inflicted instrumentation. W48 spec marked CANCELLED post- this-commit per supervisor 04:14:27Z cascade re-retract.
