Expose Worklet and AudioWorklet with shared branded prototypes and the readonly BaseAudioContext.audioWorklet attribute. Native factories bypass replaceable public constructors; each addModule call gets its own promise and rejection state.
Tests cover WebIDL conversion order, forged/proxy receivers, intrinsic factories, cross-realm results and independent module completion promises, including the existing Worker-backed module loader.
AudioWorklet execution still uses the existing per-module Worker backend. A shared AudioWorkletGlobalScope, real DSP/message ports, Blob dependency loading and complete parser/AbortError handling remain follow-up.
Tests cover top-level Window and same-origin iframe realms, plus applicable Worker globals. Popup exposure remains with the separate popup-realm migration on the integration branch; main still uses a legacy Window shell without a complete realm.
Rebased onto main, with separate exposure-list and Worker regression insertion points from WebGL, Cache and ServiceWorker.
An initial full test run hit the existing synchronous-XHR watchdog wall-clock assertion at 4.208s (limit 4s). The unchanged-tree focused recheck and subsequent full run passed, with no automatic retries; the initial log is preserved.
Expose DeviceMotionEvent and DeviceOrientationEvent in secure Window realms with native acceleration/rotation-rate payloads, WebIDL dictionary conversions and receiver branding. Create events through intrinsic constructors and check secure exposure using native realm metadata, preserving the callee realm for operation exceptions.
Tests cover nullable numeric payloads, conversion order, hostile receivers, inheritance, cross-realm calls, secure/insecure exposure and legacy createEvent. The extraction retains main's existing BeforeUnloadEvent-to-Event fallback; migrating beforeunload payload semantics is separate.
Real sensor readings and permission requests remain unimplemented.
Tests cover top-level Window and same-origin iframe realms, plus applicable Worker globals. Popup exposure remains with the separate popup-realm migration on the integration branch; main still uses a legacy Window shell without a complete realm.
Device event imports and constructor dispatch entries use separate insertion positions from WebGLContextEvent; this PR remains independent against main.
Expose the missing WebGL resource and value interfaces through the intrinsic registry in Window and Worker realms. Preserve WebGLObject inheritance for opaque resources and reject direct construction.
WebGLContextEvent uses native Event state with EventInit/statusMessage conversion and receiver checks; WebGLShaderPrecisionFormat stores existing precision-query results in native private fields behind shared readonly getters. Regression fixtures cover constructor/prototype descriptors, UTF-16 event payloads, dispatch, cross-realm receiver validation and Worker exposure.
Opaque GPU resources and WebGLActiveInfo remain interface shims; this change does not implement a GPU backend or shader reflection.
The extracted tests cover top-level Window and same-origin iframe realms. The legacy popup shell on main has no complete ECMAScript/Web API global surface; popup coverage stays with the separate popup-realm migration on the integration branch. The initial full-suite failure was confined to popup checks; it is retained in extraction logs.
Rebased onto current main. Worker regression placement is beside the existing WebGL tests, so unrelated API tests no longer all append at the end of postmessage.rs.
Expose Cache and CacheStorage in secure Window/Worker globals and attach existing cache backend objects to shared intrinsic prototypes. Keep illegal constructors, receiver validation and prototype descriptors in native bindings.
Coverage checks returned object prototypes, methods and invalid receivers, fresh results and insecure-context exclusion. Existing cache operations continue to use their current storage backend.
This is interface exposure, not a new cache storage engine: add/addAll and complete Vary semantics remain follow-up.
Tests cover top-level Window and same-origin iframe realms, plus applicable Worker globals. Popup exposure remains with the separate popup-realm migration on the integration branch; main still uses a legacy Window shell without a complete realm.
Rebased onto current main. Cache exposure entries are inserted at their own positions in the Worker and secure-context lists, separated from the ServiceWorker additions.
Use Arc<[u8]> for Binary sources in the portable module tree and renderer.
Cloning fetched sources and module-map entries now shares the original bytes
instead of copying the entire Wasm file. Compilers still borrow &[u8].
Preserve the existing policy that retains Wasm raw bytes in the module map
after compilation. Keep this change separate from synthetic text ownership.
Exercise both evaluation and source import phases through the actual module
tree compile path. Verify identical byte addresses, one remaining strong
owner after fetch temporaries are dropped, and release on document disposal.
The new regression fails with the previous Vec<u8> representation.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- cargo nextest run --no-fail-fast: 19,014 passed, 16 skipped
JSON/CSS compilation retained independent copies in the module map and the
synthetic module record. Share immutable text with Arc<str> across fetched
sources, the portable module tree, and synthetic evaluation records instead
of copying String buffers during cloning and registration.
Release the module-map source after successful JavaScript/JSON/CSS compilation.
Make fetched-source retention an exhaustive ModuleKind policy, preserving Wasm
and text-preload source semantics. Context lookups remain weak record references.
Cover the actual module-tree compile path: the record keeps exactly one strong
reference to the original text allocation after fetch temporaries are dropped,
and destroys it when disposed. Verify record clones share the same source and
Wasm entries retain their binary source.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- cargo nextest run --no-fail-fast: 19,013 passed, 16 skipped
Expose MediaDeviceInfo and InputDeviceInfo through the secure Window intrinsic registry, with the required inheritance, illegal constructors, readonly attributes and shared prototype methods. Generated receiver validation rejects forged and author Proxy receivers before running author hooks.
Serialize private native fields into a fresh callee-realm object with data properties, preserving UTF-16 and ignoring shadowed public getters or inherited setters. Tests cover main/iframe/popup interfaces, insecure contexts, Worker exclusion and native field serialization.
This is an interface shim over the current media backend: enumerateDevices() still returns an empty list, and getCapabilities() returns a fresh empty dictionary. Device discovery, permission state and real capture capabilities remain unimplemented.
Keep syntax failure separate from a non-failing scheme-state termination.
After a valid replacement is rejected, navigate the preserved HTTP(S) URL
instead of returning early on Url::set_scheme's error.
Handle permitted file transitions without credentials or a port as
non-HTTP(S) results; url 2.5.8 otherwise rejects these more broadly than
the URL algorithm. Preserve navigation for file transitions blocked by
credentials or a non-default port.
Replace the old no-navigation expectation with per-case navigation
assertions and iframe reloads that require a new Document. Cover empty
credentials, normalized default ports, and non-HTTP(S) result boundaries.
The new unit regression and iframe fixture fail on the previous PR head;
all five focused tests and all four Chromium fixture subtests now pass.
Validation: cargo fmt --all; cargo clippy --workspace --all-targets
--all-features -- -D warnings; cargo nextest run --no-fail-fast
(18,925 passed, 16 skipped). Chromium 145.0.7632.116 fixture: 4/4 pass.
Parse Location.protocol with scheme-state override rules: normalize ASCII tabs/newlines, stop at the first colon, reject invalid syntax with a DOMException and ignore incompatible or non-HTTP(S) results. Preserve navigation for an unchanged valid protocol. Tests cover invalid values, no-op schemes and queued same/changed-scheme navigations, plus a ported WPT fixture.
Validation: all branch checks passed. Summary [ 180.787s] 18923 tests run: 18923 passed (5 slow), 16 skipped
Run the full 13,631-case profile on source 112a97e61 with Moli and Chromium
145.0.7632.116 at parallelism 50, using WPT db95fafd1fcef8428805e41eb5705d444e8c67ce.
The case set and fixed scheduling order match the previous full run.
Moli: 9,540 pass, 3,704 fail, 263 timeout, 61 error, 10 crash, 53 harness-stalled.
Chromium: 11,388 pass, 1,897 fail, 242 timeout, 16 error, 18 crash, 70 harness-stalled.
All three JSON module regressions pass on both engines. Relative to 7d9a0a98c,
11 cases gain pass and five lose pass, for a net increase of six.
Keep raw full-run outcomes. Four pass losses pass once on both frozen binaries
in focused diagnostics; SharedWorker-extendedLifetime fails identically in
all three focused runs on each binary, including the pre-fix build.
Validate complete per-engine execution, exact raw/matrix agreement, and sorted,
disjoint, exhaustive status lists. No missing cases or recovery placeholders.
Accept text/json for JSON modules and use one is_json_mime classifier across
modules, documents, JSONPath, and resource inspection. Remove the module and
document aliases and recognize the seven registered application font types.
Use Fetch MIME extraction over the complete Content-Type header list for
script/style checks, workers, WebAssembly, ORB, and JSONPath. Derive classic
script charsets from the same MIME record, including charset inheritance and
resets when the MIME essence changes, while preserving BOM and fallback order.
Cover valid and invalid MIME types, header ordering, combined fields, quoted
commas, nosniff, and charset selection with regression tests.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- cargo nextest run --no-fail-fast: 19,005 passed, 16 skipped
- Focused WPT: Moli passes 9 cases / 261 subtests, including the three JSON
regressions and all 31 script Content-Type extraction checks.
Run the unfiltered all profile against WPT db95fafd1f with Moli built
from 7f9b8b63d (dev, debug=0) and Chromium 145.0.7632.116, using 50 CDP
workers. Both engines execute all 13,631 cases without setup errors,
missing results, or unexecuted recovery placeholders.
Moli: 9,534 pass, 3,708 fail, 264 timeout, 63 error, 52 harness-stalled,
and 10 crash. Chromium: 11,383 pass, 1,899 fail, 242 timeout, 17 error,
72 harness-stalled, and 18 crash.
Compared with the previous lists, 171 cases gain pass and 11 lose pass,
for a net gain of 160. Of the previous refresh's 104 pass losses, 101
now pass, two fail, and one errors. Retain the original full-run
outcomes; separate diagnostic reruns do not replace list statuses.
Validate all eight lists against the raw results and matrix: sorted,
disjoint, exhaustive, and complete. git diff --check passes.
Run unfiltered profile all on WPT db95fafd1fcef8428805e41eb5705d444e8c67ce
with Moli built from 8ba39c4aa1 and Chromium 145.0.7632.116, 50 workers.
Both engines produced results for all 13,631 cases.
Moli: 9,374 pass, 3,686 fail, 260 timeout, 247 error, 54 harness-stalled,
10 crash. Chromium: 11,334 pass, 1,888 fail, 272 timeout, 30 error,
89 harness-stalled, 18 crash.
Complete 91 previously unexecuted cases after a worker exhausted its
restart budget, using the same binary and fixture in bounded batches.
Use their first measured outcomes (63 pass, 26 fail, 2 timeout); preserve
all actual full-run failures and crashes. Both samesite-iframe and
empty-preload-response-body now pass in both engines.
Validate all eight status lists against the raw results and matrix:
sorted, disjoint, exhaustive, with no missing or unexecuted cases.
Compared with the previous refresh, 65 cases gain pass and 104 lose pass
(98 probe errors, 6 failures). Before/after diagnostic rechecks recover
31 of those 104 on the fixed binary; the other 73 also fail or error on
the old binary. Diagnostic retries do not replace full-run outcomes.
Recognize the activating version while the runtime keeps it in the waiting
slot until activate settles. NavigationPreloadManager can now enable,
disable, read state and set its header during initial activation, and the
state is persisted when activation completes.
Cover the inactive/activating boundary and persistence in a runtime test,
plus a real iframe navigation served through event.preloadResponse.
Validation: cargo fmt --all; cargo clippy --workspace --all-targets
--all-features -- -D warnings; cargo nextest run --no-fail-fast
(18,933 passed, 16 skipped). The four selected navigation-preload WPT cases
improve from 1 pass / 1 fail / 2 timeout to 3 pass / 1 fail; both the same-site
iframe and empty preload body cases now pass.
Run the unfiltered all profile on Moli c429911cdf and Chromium
145.0.7632.116 using WPT db95fafd1f and 50 CDP workers. Moli was
built from this branch with cargo build --locked (dev, debug=0).
Both engines completed all 13,631 cases without setup errors or
recovery-aborted cases. Keep the existing 13,558 cases and add 73.
Moli: 9,413 pass, 3,687 fail, 264 timeout, 202 error, 55
harness-stalled, and 10 crash. Chromium: 11,380 pass, 1,899 fail,
243 timeout, 19 error, 72 harness-stalled, and 18 crash.
Verify all eight lists are sorted, disjoint, complete and exactly
match the Moli matrix. Preserve the raw statuses, including 200
five-second CDP evaluate probe timeouts. The previous snapshot
used Moli d40181f729; this refresh is not a controlled fixture A/B.
Reconcile the shared HTTP handlers and discovery rules from the split PRs with the complete fixture surface in wpt-misc-fix. Share stash namespaces and XHR dispatch, retain the existing testdriver bridge, preserve raw header values, and carry forward the remaining pipe, template, and dynamic-import regressions.
Validation: 742 Python tests across 74 modules pass; focused Ruff checks and git diff --check pass. With fixed Moli and Chromium binaries, a 27-case WPT comparison against main improves whole-case passes from 7 to 26 and 6 to 23 respectively, with no previously passing case regressing.
Bring the remaining Fetch header fixtures from wpt-misc-fix, including early responses to unread uploads, CORS metadata, response status pipes, and handler discovery. Consolidates d210a13a5d and 8e2764e6cd with their current regression tests.
Implement preload/resources/preload-count.py and admit its exact references
during case discovery. Resource requests increment a shared counter and fail
with 404; result requests return JavaScript and consume the count. This lets
the unsupported-type WPT verify that no preload request was sent.
Validation: 432 Python WPT tests across 31 modules, run with 32 workers.
Moli and Chromium both pass the affected WPT and the two related MIME cases
(47 subtests per engine). Only Python and the WPT pass ledger changed.
(cherry picked from commit b8a3d0497d3575200ce28896c8bcde7f8c4719c4)
Serve Fetch redirect.py with upstream Origin and credentials responses,
preflight handling, query inheritance, counters, delays and form status codes.
Recognize its relative, absolute and RESOURCES_DIR references during discovery.
Cover the HTTP behavior and discovery with regressions. Verify the fixture
against upstream wptserve, including byte parsing and unread request bodies.
(cherry picked from commit 813bb1b3ecb4e55c5a0167df22494ca5269b1ef1)
Implement requri.py and redirect.py with their upstream query, status,
Location, delay, and method behavior. Preserve raw request URIs and allow
redirect responses before the upload completes.

fixtures through real HTTP requests.
Validation: all 510 benchmark unit tests pass. With the unchanged Moli
binary, 17 WPT cases improve from 6 to 9 passes and 72 to 79 passing
subtests; both redirected Worker harnesses now execute their assertions.
(cherry picked from commit 456c59b63e4ef997d35dbf984b2406a6c3c75926)
Support the iframe parentage stash fixture with write-once POST and read-once retrieval, preserving UUID/path namespaces and the difference between an absent value and empty bytes. Reuse the Python-handler response path for pipe processing. Tests cover requests, methods, body framing and case selection.
Validation: all branch checks passed. Ran 333 tests in 135.692s; OK
(cherry picked from commit 39dc2130dc)
Serve the bogus HTTP charset fixtures with their original bytes and optional valid meta charset. Match upstream response behavior for HEAD, extension methods and response-pipe bypass. Include exact reference selection and byte-level response tests.
