#11137 cc68e13 new C() on a class-valued variable typed Any

docs/src/api/reference.md conflicted on #11036 (the branch still carried the decimal.js/bignumber.js entries that #10704 removed); it's regenerated on the merged tree rather than taken from either side (2817 entries, 115 modules).

Local on the merged tree: cargo fmt, check_file_size, raw_handle_debt 897/897 (+ --no-raise-vs main), unrooted_local_shape 383, tokio_inventory, shape census, native_result_ledger, gc_runtime_root_holders, addr_class, cargo check -p perry --bins all pass.

Closes #10474
Closes #10908
Closes #10808
Closes #11128

Summary by CodeRabbit

  • New Features
    • Added support for fetch redirect modes: follow, manual, and error. Requests inherit the redirect mode specified in their options.
    • Added net.Socket.read() support, returning queued data as a Buffer and null when no data is available.
    • Web API prototype methods are now accessible as properties and can be called directly, with descriptors and enumerability aligned with Web standards.
  • Bug Fixes
    • Fixed method calls on instances created from class values so methods with names like push run correctly instead of being treated as built-in array methods.

📝 Walkthrough

Walkthrough

This PR adds fetch redirect support, paused-mode net.Socket.read(), Web builtin prototype methods, and HIR handling for instances created from dynamic class values. It also reorganizes net implementation modules and updates the workspace version to 0.5.1654.

Changes

Fetch redirect handling

Layer / File(s) Summary
Represent redirect in fetch HIR
crates/perry-hir/*, crates/perry-hir/tests/fetch_redirect_lowering.rs
Fetch option lowering stores redirect as an optional HIR expression. HIR walkers, hashing, test fixtures, and regression tests handle the field.
Pass redirect through code generation
crates/perry-codegen-js/..., crates/perry-codegen-wasm/..., crates/perry-codegen/src/...
The JavaScript and WASM paths pass redirect options to fetch. WASM runtime bridges accept the redirect argument, and compiler analyses visit redirect expressions.
Stash and resolve redirect modes
crates/perry-runtime/src/object/global_fetch.rs, crates/perry-stdlib/src/fetch/mod.rs, crates/perry-stdlib/src/fetch/request_handle.rs
The runtime stashes redirect modes separately from the existing fetch ABI. Fetch input resolution validates modes, applies defaults, and inherits a Request's mode when no init mode is supplied.
Apply redirect modes in the transport
crates/perry-stdlib/src/fetch/*, changelog.d/11066-fetch-redirect.md
Fetch dispatch maps Follow, Error, and Manual to the corresponding transport modes. Tests cover the mapping.

Paused-mode socket reads

Layer / File(s) Summary
Separate net helpers and socket tasks
crates/perry-stdlib/src/net/*, changelog.d/11036-net-socket-read.md
The net module delegates value helpers, TLS configuration, and socket task logic to child modules. The TLS verifier uses explicit imports.
Buffer and consume socket data
crates/perry-stdlib/src/net/mod.rs, crates/perry-ext-net/src/*
Both providers queue incoming bytes when no data listener exists and emit readable. Socket.read() consumes queued chunks as Buffers or returns null.
Expose read through socket dispatch
crates/perry-codegen/src/*net*, crates/perry-api-manifest/src/entries/part_1.rs, crates/perry-stdlib/src/common/*net*, docs/src/api/reference.md, test-files/test_issue_10908_net_socket_read.ts
Both provider dispatch paths recognize read. The API manifest and reference document the method, and a test checks queued data and the empty-queue result.

Web prototype methods

Layer / File(s) Summary
Install methods and prototype inheritance
crates/perry-runtime/src/event_target.rs, crates/perry-runtime/src/object/global_this/*
The runtime adds value-readable methods to Web builtin prototypes, with receiver checks and specified descriptor attributes. It links the AbortSignal/EventTarget and CustomEvent/Event prototype chains.
Check method behavior and descriptors
test-files/test_gap_10808_web_proto_methods.ts, test-files/test_gap_11003_web_proto_descriptors.ts, changelog.d/11003-web-prototype-method-values.md
Tests probe method values, calls, inheritance, and property descriptors. The changelog records the method and descriptor behavior.

Dynamic constructor method dispatch

Layer / File(s) Summary
Adjust constructor and method typing
crates/perry-hir/src/lower_types.rs, crates/perry-hir/src/lower/expr_call/*
Instances constructed through unresolved local class-value bindings now infer as Any. InstanceType receivers are treated as class instances by the affected method-fold checks.
Check dynamic and proven receiver cases
crates/perry-hir/tests/dynamic_ctor_builtin_method_names.rs, test-files/test_gap_user_method_builtin_name_dynamic_ctor.ts, changelog.d/11137-dynamic-ctor-builtin-named-methods.md
Tests cover colliding user method names on dynamic-constructor instances and controls for declared classes, arrays, and built-in constructors.

Version metadata

Layer / File(s) Summary
Update project version
Cargo.toml, CLAUDE.md
The workspace package version and the current version line change to 0.5.1654.

Merge Risk: 🟡 Moderate · up to d75e2

Fetch redirect support can reject the valid redirect: "error" mode. Typed socket.read() calls on connected sockets may return null even when data is queued. A less likely memory-safety hazard exists in the fetch thunk. These should be fixed before merging.

Explanation

The new capability-enforcement implementation in crates/perry-hir/src/capability.rs is not connected to #10474, #10908, #10808, or #11128. The file adds package capability auditing for filesystem, process, crypto, and network operations. Its test-field update for FetchWithOptions does not connect the capability feature to a linked issue. The net-module split, changelog entries, API reference regeneration, and supporting tests are in scope because they support the linked fixes.

Align the fetch_with_options import comment with its type.

t_f64_f64_f64_f64_f64 declares four I64 parameters and one I64 result. The comment lists five parameters. The emitted fetch paths use the separate mem_call bridge, so they do not justify changing this direct import type.

Inline comments:
In `@crates/perry-codegen/src/lower_call/native_table/net_events.rs`:
- Around line 405-413: Update the `net` `read` entry in `NativeModSig` to filter
for the `Socket` class and dispatch to `js_ext_net_socket_read`, so typed
`net.Socket.read()` uses ext-net’s queued socket data rather than the shared
stdlib implementation.

In `@crates/perry-ext-net/src/lifecycle.rs`:
- Around line 68-69: Update take_pending_socket_data to check the result of
alloc_buffer before NaN-boxing it; when the pointer is null, return the same JS
null value as the stdlib provider, and preserve the existing pointer encoding
for non-null buffers.

In `@crates/perry-hir/src/lower_types.rs`:
- Around line 626-627: Update the constructor type resolution guard around
`classes_index` to check the lexical binding first, matching the precedence used
by `expr_new.rs`, so a current-scope parameter or local shadowing a module class
resolves to that binding’s type. Add a regression test for a local or parameter
named `C` shadowing a module-scope `class C` and verify constructor method calls
use the lexical binding’s type.

In `@crates/perry-runtime/src/event_target.rs`:
- Around line 1196-1198: Update the initEvent thunk to reset the event’s
_stopped and _immediateStopped flags to false alongside defaultPrevented, so
re-dispatching an event does not retain propagation state; leave
js_event_target_dispatch_event unchanged.

In `@crates/perry-runtime/src/object/global_fetch.rs`:
- Around line 81-82: Update the redirect-mode parsing branch around
JSValue::is_string() to decode is_short_string() values before matching the
mode, so inline-encoded strings such as “error” are accepted; add a test that
exercises the inline representation.
- Line 780: Move the `fetch_option(init, b"signal")` lookup and
`js_fetch_set_pending_signal` call after
`js_fetch_set_pending_redirect(redirect)` so the redirect value is decoded
before the signal lookup can allocate.

In `@crates/perry-runtime/src/object/global_this/populate.rs`:
- Around line 525-546: Update the inherited EventTarget method thunks, including
the path through bound_event_target, to recognize AbortSignal receivers and
dispatch them through the AbortSignal listener implementation; preserve the
existing EventTarget handling for other receivers and leave the
AbortSignal-specific direct and dynamic bindings unchanged.

Dispatch typed net.Socket.read() to ext-net.

net.connect and net.createConnection return ext-net sockets. This row maps typed Socket.read() to the shared js_net_socket_read symbol. If the linker selects perry-stdlib's definition, the call reads NET_PENDING_READS instead of ext-net's pending_socket_data and returns null for queued ext-net data. The test does not detect this because the typed call runs before data is queued; the queued read uses the any path.

🩺 Stability & Availability | 🟡 Minor | ⚡ Quick win

Check the alloc_buffer result before NaN-boxing it.

take_pending_socket_data has already removed the chunk from the queue. If alloc_buffer returns null, Line 69 returns 0x7FFD_0000_0000_0000, which is a POINTER_TAG value with a null payload. JS code then dereferences an invalid Buffer. The stdlib twin (crates/perry-stdlib/src/net/mod.rs Line 726) returns null in this case. Return null here as well, so both providers behave the same way.

Resolve the lexical constructor binding before consulting classes_index.

When a current-scope parameter or local C shadows a module-scope class C, the guard does not match because classes_index contains C. The following branch returns Type::Named("C"), but expr_new.rs constructs the local binding. A method call can then use the module class's registered return type. This fallthrough predates this PR. Apply the same lexical-binding precedence used by expr_new.rs before selecting the class type, and add a regression test.

Clear the propagation flags in initEvent.

The DOM spec says initEvent clears the stop-propagation and stop-immediate-propagation flags. The thunk resets only defaultPrevented. js_event_target_dispatch_event never clears _immediateStopped.

Here is how the bug shows up. A listener calls stopImmediatePropagation(). Later, the code calls initEvent on the same event and dispatches it again. The second dispatch stops after the first listener. The same applies to _stopped.

🐛 Proposed fix
     event.with_mut_ptr::<ObjectHeader, _>(|event| {
         set_event_field(event, b"defaultPrevented", bool_value(false))
     });
+    event.with_mut_ptr::<ObjectHeader, _>(|event| {
+        set_event_field(event, b"_stopped", bool_value(false))

Accept inline-string redirect modes.

JSValue::is_string() recognizes heap strings only. Perry can encode the five-byte "error" value as an inline string, so this branch sets -1 and fetch rejects a valid redirect mode. The new test constructs heap strings only. Decode is_short_string() values before matching the mode, and test the inline representation. (raw.githubusercontent.com)

Decode redirect before the signal property lookup.

For a heap-string redirect, fetch_option(init, b"signal") allocates a key through js_string_from_bytes. If a moving collection is allowed, the unrooted local can retain a retired StringHeader address. The later js_fetch_set_pending_redirect(redirect) can then read stale memory. The normal allocation-point scan masks this path by retaining stack locals and disabling copying, but scan-disabled configurations can still evacuate the local.

🐛 Suggested fix
-    js_fetch_set_pending_signal(fetch_option(init, b"signal"));
     js_fetch_set_pending_redirect(redirect);
+    js_fetch_set_pending_signal(fetch_option(init, b"signal"));

Handle AbortSignal receivers in inherited EventTarget methods.

AbortSignal.prototype now inherits EventTarget.prototype. However, is_event_target does not recognize an AbortSignal: the class-chain check only follows registered class parents, while this change only links JavaScript prototypes, and alloc_abort_signal does not install the _eventTarget marker.

Therefore, EventTarget.prototype.addEventListener.call(signal, "abort", fn) reaches bound_event_target and throws Value of "this" must be of type EventTarget. The direct and dynamic signal.addEventListener(...) paths already use AbortSignal-specific bindings and are not affected.

Update the inherited EventTarget thunks to handle AbortSignal receivers through the AbortSignal listener implementation.

546, Update the inherited EventTarget method thunks, including the path through
bound_event_target, to recognize AbortSignal receivers and dispatch them through
the AbortSignal listener implementation; preserve the existing EventTarget
handling for other receivers and leave the AbortSignal-specific direct and
dynamic bindings unchanged.

Rebase of #11003 onto main, plus the two things CI was red on.

1. The #10555/#10808 conflict. Main installs `Symbol.toStringTag` on the
   URL/AbortController/AbortSignal/EventTarget/Event prototypes and, for URL,
   the twelve WebIDL component accessors; this branch installs the interface
   *operations* as real property values. They are complementary, not
   competing: WebIDL reifies an interface's attributes as accessor properties
   and its operations as data properties holding a function, and Node carries
   both on `URL.prototype` at once. Every arm now runs both installs, in
   Node's own key order for URL (`toString`, the accessors, `toJSON`).

   Each install allocates a closure, a name string and a key string, so every
   arm roots the prototype once and re-reads its current address from the
   rooted slot before each call instead of reusing the incoming raw pointer.
   `install_web_event_proto_methods` did the same thing eight times over one
   captured `proto_obj`; it now re-reads too.

2. Enumerability. WebIDL operations are enumerable, unlike ECMAScript builtin
   methods, so each one overrides `install_proto_method`'s default. The single
   exception is `AbortSignal.prototype.throwIfAborted`, which Node makes
   non-enumerable alongside its `reason` accessor; it is installed with no
   override and the site records the measured descriptor so a later "cleanup"
   into a uniform helper does not silently diverge.

3. `lint :: Raw-handle debt ratchet`, which is independent of the conflict.
   The EventTarget receiver check added two bare `get_raw_mut_ptr` reads in
   `bound_event_target`, taking event_target.rs from 16 to 18. `is_event_target`
   interns `_eventTarget` through `key()`, which allocates, so the receiver can
   genuinely move while the predicate runs: the pair collapses into one
   `across_mut` whose nested `with_const_ptr` scopes the pointer the predicate
   reads, and whose returned address is the post-call re-read. Back to 16 with
   no ceiling raised and no allowlist entry.

Adds `test_gap_11003_web_proto_descriptors.ts`, which pins the descriptor
shape (kind, enumerable, configurable, writable) plus an independent
`Object.keys` read for a URL operation, a URL accessor, an EventTarget
operation, `AbortSignal.throwIfAborted`, and two ECMAScript builtins as the
non-enumerable contrast. Gap tests are diffed byte-for-byte against the
pinned Node oracle, so the enumerability split is asserted rather than
rediscovered.

…he manifest

Two required steps were red on #11036; neither is a defect in what the PR does.

`lint :: File size limit` — `crates/perry-stdlib/src/net/mod.rs` was 1968 lines
on main and this PR's `js_net_socket_read` + `NET_PENDING_READS` pushed it to
2006, six over `scripts/check_file_size.sh`'s hard 2000-line cap. Split into
three sibling modules, re-exported from `mod.rs` with explicit named `use`:

  value_helpers.rs (247)  NaN-boxed JS value/object readers
  tls_config.rs    (358)  TLS option parsing + rustls connector construction
  socket_task.rs   (281)  the per-socket tokio task and TLS handshake recording
  mod.rs          (1181)  handle storage, the FFI surface, the event pump

Pure move: every moved item keeps its name, signature, doc comment, attributes
and `#[cfg(feature = "tls")]` gating; the only edit is `pub(super)` on the ones
`net` still calls. All 18 `#[no_mangle] pub extern "C"` symbols stay in
`mod.rs`, verified identical before/after. `net/tls_verifier.rs` needed explicit
`rustls` imports in place of its `use super::*;` — the danger-trait names it
relied on were re-exported from `mod.rs`, and a glob does not carry them once
they move.

No path-keyed gate entry moved: `gc_runtime_root_holders.json`'s two entries for
this file (`NET_GC_REGISTERED`, `SCRATCH`) both name items that stayed in
`mod.rs`; `addr_class_ratchet_baseline.txt`, `addr_class_allowlist.txt`,
`raw_handle_debt_files.txt` and `shape_descriptor_census_baseline.json` have no
entry for it. All five scripts re-run green, including
`raw_handle_debt.py --no-raise-vs origin/main` (no relocation to declare).

`cargo-test :: Run cargo test` — `perry-codegen`'s
`manifest_consistency::every_dispatch_entry_has_manifest_counterpart` asserts
every `NATIVE_MODULE_TABLE` row has an `API_MANIFEST` counterpart. The PR added
the `net::read` dispatch row without one, so the check reported
`net::read (has_receiver=true, class_filter=-)` missing. Added
`method("net", "read", true, Some("Socket"))` next to the other `net.Socket`
instance methods, and regenerated `docs/src/api/reference.md`, which the
`api-docs-drift` job would otherwise have caught next (one new line plus the
entry count; `docs/api/perry.d.ts` is unchanged, since instance methods are not
module exports).

Re-ported onto the post-train-266 `main`, where #11102 moved perry-stdlib's TLS
off `tokio-rustls` onto `perry-tls-session` via `crate::tls_stream::TlsStream`.
The split is redone against that tree, not transplanted: `tls_config.rs` names
`rustls` directly and owns the `type TlsConnector = Arc<rustls::ClientConfig>`
alias `build_tls_connector` now returns; `socket_task.rs` handshakes with
`TlsStream::connect(tcp, connector, server_name)` and reads the negotiated
session through `stream.session()` instead of `get_ref().1`; `tls_verifier.rs`
takes `rustls::client::danger::*` rather than the `tokio_rustls` re-export.
Verified as a pure move of main's content: the four files' function sets and
their non-import lines are multiset-identical to main's `net/mod.rs` plus this
PR's `Socket.read` work.

(cherry picked from commit d8a32cb)
Ports PR #11066. Its original home, `crates/perry-ext-fetch/`, was deleted
by the turnloop migration (#10354) and folded into
`crates/perry-stdlib/src/fetch/`, so the PR can no longer apply.

`RequestInit.redirect` now survives AST->HIR lowering on
`Expr::FetchWithOptions` and reaches the transport through the runtime's
pending-option stash (`js_fetch_set_pending_redirect` /
`js_fetch_take_pending_redirect`) — the same trick `init.signal` uses, so
`js_fetch_with_options`' 4-argument ABI is unchanged. `fetch(Request)`
inherits the Request's own mode when `init` carries none; a mode that is
not follow/error/manual rejects with a TypeError.

The transport is the turnloop client engine — there is no other one since
#11101 removed perry-stdlib's reqwest fallback. It hardcoded
`RedirectMode::Follow`, so `manual` and `error` would have behaved as
`follow` while the lowering tests passed. `FetchDispatch` now carries the
mode and `turnloop_bridge::engine_redirect` translates it; the engine
already implements all three and already reports `final_url` /
`redirected`, which is where `response.url` and `response.redirected` come
from.

Rebased onto the post-train-266 `main`, where #11101 deleted the reqwest
half this PR originally patched. Dropped as newly-dead code, not ported:

* `abort_bridge::run_request` — deleted by #11101 along with
  `race_request`; the redirect-mode client selection and the
  `response_url_metadata` call inside it have nothing left to patch.
  Only the module note's mention of the redirect bridge is kept.
* `fetch/client.rs` — the split this PR introduced existed to keep
  `mod.rs` under the 2,000-line cap while holding a follow/no-redirect
  PAIR of `reqwest::Client`s (reqwest sets redirect policy on the client,
  not the request). With reqwest gone, `mod.rs` is 1,576 lines and every
  function in that file — `build_fetch_client`, `fetch_client`,
  `fetch_client_for_redirect`, `build_proxy_client(s)`,
  `apply_node_tls_environment`, `response_url_metadata`,
  `redirect_response_is_error` — is dead. Only `FetchRedirectMode`
  survives, and it moves back into `mod.rs`.
* `HTTP_CLIENTS` / `GLOBAL_PROXY_CLIENTS` and the `build_proxy_clients`
  install path — `main`'s `js_fetch_set_global_proxy` stores a normalized
  `(uri, token)` for the engine instead of prebuilding clients.
* the `redirect_clients_expose_follow_and_manual_responses` test, which
  drove two reqwest clients against a local `TcpListener`. Its subject no
  longer exists. `fetch_redirect_mode_maps_onto_the_engines_redirect_mode`
  (also from this PR) is kept and is now the transport-side coverage.

Rebased onto main 48fb81c after the direct merges of #11141/#11144/#11118/#11126/#11083/#11057/#11107. CI on the previous head d75e2b0 was green except the owner-grandfathered public-baseline step (+ pr-gate fan-in); cargo-test's one failure there was an ETXTBSY race in commands::run::entry (untouched by this train) and passed on re-run.

The only conflict was #11107's aws_lc_rs → ring provider swap against #11036's split of net/mod.rs: the five moved TLS functions in net/tls_config.rs are byte-identical to main's after applying the same swap. The normalized patch vs d75e2b0 differs in exactly those six provider lines. aws-lc-rs is no longer in the graph, so a missed site cannot compile.

Local on the rebased tree: fmt, file size, raw_handle_debt (+ --no-raise-vs main), unrooted_local_shape, tokio_inventory, shape census, native_result_ledger, gc_runtime_root_holders, addr_class, socket-open invariant, API-docs regen (no drift), cargo check -p perry --bins, RUSTFLAGS=-D warnings --all-targets for perry-stdlib/perry-ext-net/perry-runtime, and perry-stdlib tls tests (8/8) all pass. Force-merging on owner instruction without a fresh CI cycle.
