Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk: 🟠 High · up to This PR changes production code generation and runtime behavior for App Route dylibs, but the current head still has unresolved call-ABI cases that can mis-handle JavaScript methods, fault-reporting paths that can lose diagnostics or fail during a memory fault, and a macOS release fixture that may not link. The release verifier also does not enforce the stated exact response parity, so these issues should be addressed before merging. Possibly related issues

Blocking correctness regression: is_current_class_self ignores an existing method-local binding. In JavaScript, class C { static make(C) { return new C(); } } must construct the constructor passed in parameter C; Node 26 returns true for C.make(D) instanceof D. This branch forces the enclosing class instead because the source identifier matches current_class_inner_name, even when lookup_local finds the parameter. Please distinguish the class lexical binding from nearer method parameters/locals and add this shadowing regression alongside the outer-var positive case.

The forced/verified acceptance arm is vacuous as checked in: it sets FORCE_EVACUATE and VERIFY, but does not positively require a collection or a non-in-place move, and does not enable diagnostics from which that can be asserted. A run with zero collections passes all current checks. Please arm a deterministic moving workload and use the existing evacuation-liveness checker (or an equally strict copied/promoted non-in-place assertion) so closing #8036 proves forced GC was actually exercised.

rewrite-statepoints-for-gc wraps every non-leaf call in a gc function into a gc.statepoint — including the empty `asm sideeffect` loop- preservation barrier, whose statepoint form (`ptr elementtype(void ()) asm ...` as callee) is verifier-invalid: 'Cannot take the address of an inline asm!'. The external opt path aborts on its verifier; the in-process pipeline ran no post-rewrite verify, so the broken module reached ISel and died as a bare KERN_PROTECTION_FAILURE SIGBUS with no diagnostic (#8082, the jsonwebtoken unit of the Next production fixture — reproduced twice at the same module). Stamp "gc-leaf-function" on the barrier at all three emission sites (text render, dialect text parse, dialect enum) — an empty asm can never reach a safepoint, so the exemption is sound by construction — and verify the module after the in-process rewrite so any future RS4GC-invalid shape fails loudly instead of crashing the backend. Regression tests cover both directions: the attributed barrier survives unwrapped beside a still-statepointed real call, and the unattributed shape is rejected, not miscompiled.

Under the default native-roots build every JS catch pad is `landingpad token cleanup` (#7982's statepoint retype of catch-alls whose payload is unused), and LLVM emits a ZERO call-site action for a cleanup clause. Nothing pinned that, so reading the action as 'handler vs cleanup' looks reasonable in review while silently skipping every statepoint-built catch — a plain `try { throw } catch` then aborts FATAL 'no landing pad'. Exactly that regression was written and reviewed on #8082 and only caught end-to-end. Also add PERRY_EH_TRACE=1: one line per personality invocation (phase, owning function via dladdr, ip offset, decoded pad), the instrument that hunt lacked. Cached OnceLock probe, no verdict change.

…rown functions (#8128) * fix(codegen): optnone post-RS4GC relocation-bloated functions The #4880 opt-tier plan is computed from pre-rewrite sizes, but rewrite-statepoints-for-gc's relocation fan-out grew one 51k-line minified Next chunk closure 40x to 2.1M instructions, and a single -Os function pass then ran 65+ CPU-minutes without finishing. Measured on the #8036 fixture: the unit's IR went 27MB -> 581MB while its five sibling units grew ~4x and compiled in 38-178s. After the in-process rewrite, stamp optnone+noinline on any function past 512k instructions (PERRY_LL_RS4GC_OPTNONE_INSTRS; largest known-fine function is ~413k) so the pipeline skips exactly the exploded functions and still optimizes their siblings; the stuck unit now finishes default<Os> in ~21s. optnone gates only the middle-end, so the statepoint lowering and compact GC map are unaffected. The external text path re-parses the rewritten text and already re-derives its opt tier from post-rewrite sizes. * fix(codegen): reserve deep stacks for LLVM unit workers The app-dylib compile SIGBUSed (no crash report) immediately after the second optnone demotion fired, while an LLVM unit carrying a multi-million-instruction post-RS4GC function was in flight on a scoped worker with Rust's default 2 MiB stack. LLVM pass and ISel recursion scales with function size, and a guard-page hit on a worker thread presents exactly this way. Reserve 64 MiB per unit worker — address space, not resident memory, until touched. * fix(codegen): exempt the inline-asm loop barrier from RS4GC rewrite-statepoints-for-gc wraps every non-leaf call in a gc function into a gc.statepoint — including the empty `asm sideeffect` loop- preservation barrier, whose statepoint form (`ptr elementtype(void ()) asm ...` as callee) is verifier-invalid: 'Cannot take the address of an inline asm!'.

The raw-handle ratchet locks array/generic.rs at zero bare get_raw_*_ptr reads, and #7341's direction is conversion rather than a raised ceiling. Convert by shape: - js_arraylike_map's post-callback reload becomes across_mut, which is a strictly better spelling here: the pre-call address is never bound, so the stale pointer the #8082 fault wrote through is not nameable at all rather than merely re-read. - the js_array_push_f64 call and both nanbox_arr tails become with_mut_ptr — push is self-rooting for the array it is handed (its grow path roots and re-reads it) and returns the current address, and nanbox_arr only tags the pointer. Behaviour is unchanged: the value pushed is still read from its handle before the call, exactly as before. The moving-GC regression still fails when the element pointer is hoisted back out of the reload, so the conversion did not weaken it.

… ext-http (#8131) * fix(runtime): root the generic array-like callback loops across their collection points The forced-moving production gate faulted inside js_arraylike_map with from-space protection armed: the loop derived the result array's element pointer once, the callback's allocation ran a copying minor that moved the array, and the next mapped element was written through the pre-collection pointer into mprotect-poisoned retired from-space (obj_type=1, the result array). Every callback-iteration helper in array/generic.rs shared the shape: receiver, callback, result under construction, and (in find/filter) the current element were all held in raw locals across js_closure_call3/4 — and al_has/al_get, whose getter and proxy paths run arbitrary JS, are collection points too. Root all of them in a RuntimeHandleScope and re-read from the handles at every use: forEach, map, filter, some, every, find, findIndex, findLast, findLastIndex, reduce, reduceRight. The closure pointer is re-derived from its rooted nanbox adjacent to each call instead of being cached across iterations. The regression test plants the gate's exact collection point — a callback that runs a copying minor on every invocation — and asserts the relocated receiver is observed and the mapped values land in the relocated result. Sabotage-verified: re-hoisting the element pointer makes it fail. * fix(runtime): root call/apply and put-value locals across their JS invocations The forced-moving gate faulted twice more in the same class: the Function.prototype.call/.apply arms held the callee closure, the explicit this, and the saved implicit-this bits in raw locals across js_native_call_value, then handed the stale callee to maybe_alias_explicit_this_construction; and js_put_value_set held the receiver and property key across ordinary_set_with_receiver (which runs user setters) before the array-subclass length note read the stale receiver's header. Root all of them in RuntimeHandleScopes and re-read from the handles after the calls. * fix(ffi): transient GC roots for ext-crate callback snapshots Ext crates keep user closures in handle-struct side tables that registered scanners rewrite on a moving collection — but a SNAPSHOT of those tables in a Rust local (a cloned listener Vec, a pending-request struct parked in an mpsc channel between the hyper task and the pump tick) is a copy no scanner can see. The forced gate faulted on both shapes: a drained listener vec went stale after the first callback's collection, and channel-parked handler/listener addresses went stale across the microtask-pump safepoint minors that run while requests wait. Add an extern transient-root surface over the runtime-handle stack (js_ffi_root_scope_enter/push/get/exit) plus a safe perry_ffi::TransientRootScope wrapper, and convert perry-ext-http's emit helpers, deferred-listen drain, close callback, and both process_pending dispatchers. The HTTP/HTTPS dispatchers additionally re-read handler and listener lists from the scanner-maintained server handle at dispatch time instead of trusting the channel-parked snapshot (the arrival-time is_check_continue routing decision is kept). * feat(gc): sharpen the from-space scan and stack-map walk instruments - Bound the from-space scan's array walk by the LIVE length: capacity slack holds whatever bytes the allocator or a verbatim minor copy left there, and decoding it produced false MISSING-REWRITE aborts on the #8036 gate (a length-8/capacity-16 array whose slack held a dead method-table fragment). - Append a payload preview to each offender report (classified words around the stale slot) so the owner identifies itself. - PERRY_GC_STACKMAP_TRACE=1 prints each frame the native stack-map walk visits (ip + dladdr name); it is how the '7-frame truncated walk' hypothesis was falsified — those are complete walks at the microtask-pump boundary with no JS frames on the stack. * test(eh): pin that an action-zero landing pad is still Perry's catch Under the default native-roots build every JS catch pad is `landingpad token cleanup` (#7982's statepoint retype of catch-alls whose payload is unused), and LLVM emits a ZERO call-site action for a cleanup clause. Nothing pinned that, so reading the action as 'handler vs cleanup' looks reasonable in review while silently skipping every statepoint-built catch — a plain `try { throw } catch` then aborts FATAL 'no landing pad'. Exactly that regression was written and reviewed on #8082 and only caught end-to-end. Also add PERRY_EH_TRACE=1: one line per personality invocation (phase, owning function via dladdr, ip offset, decoded pad), the instrument that hunt lacked. Cached OnceLock probe, no verdict change. * fix(ext-http): make the GC scanner tests force evacuation, and drop the now-dead listener snapshot Two pre-existing failures on main (not introduced here): the scanner tests assert a root was REWRITTEN, which is only observable if the collection actually MOVED the object — a C4b policy decision that legitimately declines under unit-test conditions, at which point the assertions fail with nothing wrong in the code under test. The guards now force evacuation for their (mutex-serialized) lifetime, so the subject is guaranteed live. perry-runtime's own ForcedEvacuationTestGuard is #[cfg(test)]-internal and unreachable from this crate's test binary; the env knob is read fresh per query. Also drop HttpPendingRequest::check_continue_listeners, which the dispatch rooting fix orphaned: the addresses are now re-read from the scanner-maintained server handle, and only the routing bit is carried across the channel. * docs: changeset for the moving-GC rooting sweep * refactor(gc): use the sanctioned handle accessors in the arraylike loops The raw-handle ratchet locks array/generic.rs at zero bare get_raw_*_ptr reads, and #7341's direction is conversion rather than a raised ceiling. Convert by shape: - js_arraylike_map's post-callback reload becomes across_mut, which is a strictly better spelling here: the pre-call address is never bound, so the stale pointer the #8082 fault wrote through is not nameable at all rather than merely re-read. - the js_array_push_f64 call and both nanbox_arr tails become with_mut_ptr — push is self-rooting for the array it is handed (its grow path roots and re-reads it) and returns the current address, and nanbox_arr only tags the pointer. Behaviour is unchanged: the value pushed is still read from its handle before the call, exactly as before. The moving-GC regression still fails when the element pointer is hoisted back out of the reload, so the conversion did not weaken it. --------- Co-authored-by: Ralph Küpper <ralph@skelpo.com>

#8081 rebuilds the runtime's stack-map index at module init and discovers compact GC maps in every loaded Mach-O/ELF image, so the demotion of dylib artifacts to the shared shadow stack is obsolete — and would leave provider apps running a lowering production never ships (it also breaks the gc-native-roots provider gate, which asserts the app map survives dead stripping). Drop set_native_roots_for_artifact and pin the native lowering in the entry test instead.
The rebase re-inlined timer's drain_expired_tests (main had already externalized the identical tests to timer/drain_expired_tests.rs) and this PR's additions pushed object/mod.rs and cjs_wrap/mod.rs over the cap. Restore main's external timer test file, move the call-method depth guard family to object/call_method_depth.rs, and move cjs_wrap's inline test module to cjs_wrap/tests.rs verbatim. Also register PERRY_LL_RS4GC_OPTNONE_INSTRS as a build-cache key (#6394's rule, caught by codegen_env_vars_are_build_cache_inputs).
TEST_BOUND_METHOD_MOVE is #[cfg(test)] diagnostic storage recording the (before, after) addresses of a test-forced relocation; compared as integers, never dereferenced, absent from shipped binaries.
…e consumer The quarantine's fault report answers 'who used it' — the consumer, which for a value read out of a table one instruction earlier is never the bug. PERRY_GC_PROTECT_FROMSPACE_HOLDERS=1 adds the other half: a whole-heap sweep at fault time for any live word that decodes to the faulting address (or to the user pointer of the object that used to live there), printed as owner/obj_type/offset. Applied to #8036's forced-moving fault it is already decisive: NO arena object holds the stale closure, so the holder is outside the GC heap — a runtime side table, an FFI structure, or a frame slot — which is why the whole-heap from-space scan could never name it. Quarantined pages are skipped (they are PROT_NONE; reading one from the handler would fault recursively) via a try_lock'd snapshot of the registry, matching the census lookup above it. Also carries the from-space scan's owner/target header dump, which is what identified the earlier offenders as dead old-gen residue rather than live misses.
… the changeset Two rebase corrections now that #8128 and #8131 have landed. The review pass on this branch introduced a Handler/Cleanup split in perry_eh_personality keyed on the LSDA call-site action. main never had it, and it is wrong: #7982's statepoint retype makes every JS catch pad a token-cleanup pad with a ZERO action, so the split skips every statepoint-built catch and a plain try/catch aborts FATAL 'no landing pad'. main's eh.rs is authoritative (it also carries the regression test and PERRY_EH_TRACE that went in via #8131), so take it wholesale. The changeset now describes only what remains here: the fixture, the dylib native-roots decision, the production-path lowering fixes, and the holder sweep. Everything else moved to #8128/#8131 with its own fragments.
The raw-handle ratchet caps object/native_module.rs at 4 bare get_raw_*_ptr reads and this branch's bound-method rooting took it to 22. Convert by shape rather than raise the ceiling (#7341): - the capture-slot writes, name/length stamps, null check, write barrier and nanbox tails become with_mut_ptr — scoped arguments to non-allocating stores, with each value read from its own handle first, so behaviour is unchanged; - the test hook's reload around gc_collect_minor becomes across_mut, which is what it was hand-rolling. Also route the holder sweep's header read through addr_class::try_read_gc_header instead of a bare cast, so it rejects handle-band and small-buffer-slab addresses (which carry no header) before dereferencing — the addr-class ratchet's point. Ratchet back to 992 = baseline. Sabotage-verified: returning the pre-collection address from the builder still fails bound_method_builder_reloads_closure_and_receiver_after_collection.

The fixture's production-parity coverage — untouched Next 16.3.0 webpack output compiled as an app-only dylib against separate runtime and stdlib providers, 10 cold starts of two 21-request verifier passes each against the Node production oracle — passes today. Its forced-evacuation arm does not: a stale closure reaches Next's Reflect.get adapter from a holder that is outside the GC heap and registered with no root scanner (#8163 carries the elimination trail and a seconds-long reproducer). Ship that arm behind PERRY_NEXT_ROUTE_FORCED_GC=1, off by default. Deliberately not a SKIP, which would read as covered, and deliberately not continue-on-error, which would make it documentation rather than a gate: OFF here, FAILS LOUDLY when set. The PASS line names which arms ran so a green result cannot overstate itself.

Out of draft. The forced-evacuation arm is split to #8163 and the fixture now gates the production path on its own. Why split rather than hold the PR. The fixture's production-parity coverage passes today; one arm of it does not, and that arm's bug is independent of everything else here (it reproduces identically under How the arm is disabled matters, so it is worth being explicit: not a Full fixture run at Checked that the subject actually ran rather than trusting the line: 10 cold-start logs, 20/20 verifier passes (10 starts × 2), against the Node oracle. Also folded in on the rebase, since #8128 and #8131 landed: their commits dropped out by patch-id (17 → 9), and the branch's own landing-pad regression went with them — the review pass here had added a Handler/Cleanup split keyed on the LSDA action, which Suites at this head: |

943-948: 🚀 Performance & Scalability | 🔵 Trivial | ⚡ Quick winBound the sweep instead of passing
usize::MAX.Line 944 gives the cursor an unlimited budget. The loop exits early only after
MAX_REPORTEDmatches. When there are no matches, the handler walks the entire heap word by word before it prints the "none" line at line 993. On a large heap this delays or prevents the re-fault at lines 857-862, and a crash reporter or CI timeout may kill the process first.Set a finite budget and report when the budget is exhausted, so the output distinguishes "no holder" from "sweep did not finish".

In `@changelog.d/8082-next-production-app-route.md`:
- Around line 26-34: Update the pinned Next production App Route fixture
description to state that forced-evacuation cold starts are optional and
excluded from the default gate, rather than claiming half of the default runs
use them. Preserve the description of GC diagnostics and liveness assertions
only as applying when that opt-in arm is enabled.
In `@crates/perry-codegen/src/lower_call/property_get/dynamic_dispatch.rs`:
- Line 1029: Update the typed direct-path condition in the dynamic dispatch
logic to also exclude methods where fallback_has_synthetic_arguments is true,
not only those with fallback_has_rest. Route either case through the ABI-adapted
generic path so synthesized arguments slots are preserved.
- Around line 178-220: The argument-lowering logic must support methods with
both has_rest and has_synthetic_arguments instead of treating them as exclusive.
In the direct_args construction, exclude both hidden ABI slots from fixed
positional arguments, then append the ordinary rest array and synthesized
arguments array in formal-slot order, preserving undefined filling for missing
fixed values. Apply the same ordering fix to the corresponding dynamic- and
virtual-dispatch paths and add coverage for Reflect.apply using arguments in a
method declared with rest parameters.
In `@crates/perry-runtime/src/arena/quarantine.rs`:
- Around line 899-908: Resolve PERRY_GC_PROTECT_FROMSPACE_HOLDERS when
installing the from-space fault handler, store the enabled state in an
AtomicBool, and make fromspace_fault_handler perform only an atomic read before
applying the gate. Remove OnceLock and environment access from the handler, and
update its doc comment to no longer claim the path takes no potentially blocking
locks.
In `@crates/perry-runtime/src/gc/fromspace_scan.rs`:
- Around line 374-382: In crates/perry-runtime/src/gc/fromspace_scan.rs:374-382,

crate::value::addr_class::try_read_gc_header and print a placeholder when it
returns None. In crates/perry-runtime/src/arena/quarantine.rs:921-952, return
early from the quarantine scan when the range snapshot is incomplete due to
try_lock failure or exceeding 64 blocks, rather than using an incomplete
quarantined filter.
In `@crates/perry/src/commands/compile/build_cache.rs`:
- Line 99: Remove the duplicate PERRY_LL_RS4GC_OPTNONE_INSTRS entry from the
build-cache input list, keeping the existing earlier entry unchanged so the
fingerprint includes it only once.
In `@crates/perry/src/commands/compile/cjs_wrap/tests.rs`:
- Around line 1884-1893: Update the assertions in the test around the wrapper
markers to require both searches to succeed, using expect as in
issue_5251_class_reading_exports_stays_in_iife; then compare the unwrapped
indices to verify class C remains inside the IIFE.
In `@tests/release/packages/next-app-route/fixture.sh`:
- Around line 81-93: Update the Node oracle flow around verify.mjs to capture
each request’s status, raw response body, and required headers, then persist
those values for comparison. Extend the Perry verification flow to compare its
corresponding responses byte-for-byte and header-for-header against the captured
Node oracle results, rather than relying only on semantic JSON checks; preserve
the existing startup and cleanup behavior.

Correct the forced-GC release-note claim.
Lines 31-34 state that half of cold starts run under forced evacuation. The default fixture leaves that arm disabled, and the opt-in arm currently fails loudly pending #8163. Describe it as optional and not part of the default gate.

Support methods that use both rest parameters and arguments.
A JavaScript method can declare ...rest and reference arguments.
The if has_synthetic_arguments { ... } else if has_rest { ... } branch treats these ABI slots as mutually exclusive.
Build the fixed positional arguments with both hidden slots excluded. Then append the ordinary rest array and the synthesized arguments array in the generated method’s formal-slot order.
Add dynamic-dispatch and virtual-dispatch coverage for method(...rest) { return Reflect.apply(target, this, arguments); }.

Exclude synthesized-arguments methods from typed direct paths.
This condition only excludes ordinary rest parameters.
When fallback_has_synthetic_arguments is true, the typed receiver path can construct typed_args without preserving the hidden synthesized-arguments ABI slot. Fall back to the ABI-adapted generic path for these methods.

Resolve the env flag before the fault, not inside the handler.
std::env::var is not async-signal-safe. It allocates and it reads the process environment, which another thread can mutate. OnceLock::get_or_init also runs initialization under a lock. Both now execute inside fromspace_fault_handler on the first fault.
The gate runs even when the feature is off, so every SIGSEGV in a build with from-space protection installed pays this cost. A hang or a secondary fault here destroys the always-on fault report at lines 810-837, which is the part that already works.
Read the variable when the handler is installed and store the result in an AtomicBool. The handler then reads one atomic.

New GC diagnostics can fault on from-space while they report a from-space fault. Both new diagnostic paths reach addresses that may be retired from-space or PROT_NONE without first proving the address is readable. When PERRY_GC_PROTECT_FROMSPACE is active, the diagnostic crashes and the original report is lost, which defeats the purpose of the instrument.

Make this test fail when the markers are missing.
Both offsets are optional, so the test passes without asserting anything if the wrapper stops emitting const _cjs = (function() or renames class C . The hoist guard would then regress undetected. Use expect on both offsets, as issue_5251_class_reading_exports_stays_in_iife does at Lines 967-972.

Lines 81-93 discard the Node responses. Lines 177-178 run the same semantic verifier against Perry. verify.mjs parses JSON and checks selected fields, so raw body differences and unasserted header differences can pass. This does not meet the byte-for-byte parity claim in Lines 4-8.

No project version bump.
