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.
Recognize supported XHR references during case selection and cover the
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.
Validation: all branch checks passed. Ran 325 tests in 122.514s; OK
(cherry picked from commit 9827403ad3)
Serve the WPT content-type fixture as its original raw HTTP response, preserving duplicate, empty and malformed Content-Type fields and response bytes. Support standard and extension methods without consuming irrelevant uploads. Tests cover wire output, HEAD, pipelines and exact case selection.
Validation: all branch checks passed. Ran 329 tests in 129.466s; OK
(cherry picked from commit 252861d9c8)
Serve the form-submission body checker for GET, HEAD and POST. Preserve its exact URL-encoded and plain-text checks and MIME-aware multipart field parsing, including duplicate fields, file parts and transfer-encoding boundaries.
(cherry picked from commit 83c8955175)
Serve Fetch preflight and stash cleanup endpoints with method/header validation and shared request state. Preserve repeated query and origin values, exact resource namespaces and immediate responses for unused uploads.
(cherry picked from commit 807abbe05b)
Model service worker script redirects, versioned imports and update response sequences, including file-based and installation updates. Preserve request methods, cache metadata, raw script bytes and per-resource state shared across fixture origins.
(cherry picked from commit 5d0ddf013b)
Model xhr/resources/headers.py with its duplicate, empty, cookie and non-ASCII response headers. Include HEAD behavior and precise fixture discovery regression coverage.
(cherry picked from commit 8557f41b0c)
Serve malformed chunk framing and the upstream infinite redirect loop instead of Python source. Preserve raw partial body delivery, origin and query parameters, HEAD semantics, and exact fixture discovery.
Source: 0de7826105
(cherry picked from commit 0f4acf2725)
Consolidate #552 and #938 on top of the IDNA and nested-domain support already in main. Preserve the requesting host for location templates and use web-platform.localhost in the cross-engine runner.
Normalize an empty Target.createTarget URL to about:blank before constructing the renderer command so initial target metadata and navigation state agree. Regression coverage exercises default and browser-context target creation.

Give document decoding explicit HTML, XML, and text declaration policies.
XML ignores HTML meta elements, retains BOM and transport charset precedence,
and selects an initial XML declaration or UTF-16 signature before its UTF-8
default. Keep partial declarations and signatures buffered across chunks.
Cover conflicting meta declarations with and without an XML declaration,
including main documents, iframes, and external raw input. Adapt seven
Chromium XML/XHTML navigation scenarios and three decoder boundary tests
from Chromium a03603fe9af6230a12f1b2fb2c18a7d003a0d937; source paths are
recorded next to the tests. These include KOI8-R script inheritance, CP1251
XML, BOM-less UTF-16, supplementary Unicode characters, and BOM boundaries.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- XML and Chromium regression tests passed.
- NEXTEST_TEST_THREADS=8 cargo nextest run --no-fail-fast:
18,980 passed, 16 skipped.
Keep network XML response bytes intact through the existing raw-body renderer
path. Decode both network and external XML bodies with the shared response
decoder, then install the selected encoding before document bootstrap.
Remove the obsolete ready-body capture variant used by the old XML path.
Cover matching main-document and iframe text, namespaces, and characterSet for
Atom, RSS, and text/*+xml responses with Windows-1252 headers, XML declarations,
and UTF-16LE/BE BOMs. Exercise the external input as single-byte chunks and
verify that BOMs override a conflicting transport charset.
Validation:
- Before the fix, the network regression returned caf� / UTF-8 instead of
café / windows-1252.
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- Six focused XML tests passed.
- NEXTEST_TEST_THREADS=8 cargo nextest run --no-fail-fast:
18,954 passed, 16 skipped.
Keep valid inherited text encodings ahead of heuristic detection while
preserving BOM, transport charset, and JSON default precedence. Share the
response decoder between streaming main documents, asynchronous child
loads, data URLs, and blocking child snapshots.
Classify navigation XML MIME types independently of DOMParser's allowlist,
including +xml subtypes in parser routing and text exclusions. Add
regressions for inherited UTF-8, literal encoding declarations, XML
namespaces, and DOMParser rejection of navigation-only XML types.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- NEXTEST_TEST_THREADS=8 cargo nextest run --no-fail-fast
18,952 passed, 16 skipped. Two existing timing tests failed under the
default concurrency, then passed individually and in the full run above.
Apply the shared script nonceability check to parser scripts, buffered preloads and runtime script preparation. Suspicious script attribute names and values must not authorize execution merely because a nonce matches. Includes parser, preload and dynamic-preparation regressions.
The attribute checks follow the [CSP3 nonceability algorithm](https://www.w3.org/TR/CSP3/#is-element-nonceable), including case-insensitive `<link`, `<script` and `<style` matches and parser duplicate attributes.
Validation: all branch checks passed. Summary [ 115.690s] 18925 tests run: 18925 passed (9 slow), 16 skipped
Avoid materializing a document style world during font reconciliation when no font state, style state or active author stylesheet exists. Keep document and connected shadow-root adopted sheets observable, and retain reconciliation after any state has been published. Tests cover the lazy path and shadow adopted-sheet sources.
Validation: all branch checks passed. Summary [ 104.769s] 18923 tests run: 18923 passed (9 slow), 16 skipped
Gate both popup same-document fast paths on GET, a non-null target fragment and non-reload navigation. Repeated fragmentless GET submissions now load a new document through the normal navigation path.
Exercise two GET and POST submissions for each popup target with no-store responses, checking actual requests and document replacement. Verified the GET regression fails before the fix.
Validation: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo nextest run --no-fail-fast (18945 passed, 16 skipped).
Share the native document browsing-context check with visibility getters. Route popup self, parent and top submissions through popup navigation, preserving POST requests and fetching again for same-URL POSTs.
Cover real GET/POST requests, borrowed submit methods, repeated POST, navigation cancellation and closed popup documents. Validation: cargo fmt --all; cargo clippy --workspace --all-targets --all-features -- -D warnings; cargo nextest run --no-fail-fast (18945 passed, 16 skipped).
Carry the selected control or image query into RadioNodeList descriptors
and reuse the same matching helpers when resolving live collections.
Retained image lists keep their filter when matching controls are added,
and retained control lists never switch to image fallback.
Cover image membership, descriptor access, name changes, tree order,
removal, and adoption while preserving form.elements control filtering.
Replace the native-member name allowlist with real own-property checks
using the incoming V8 name. Keep definition restrictions separate from
named-property visibility so Reflect.defineProperty returns false while
Object.defineProperty throws for supported names.
Cover own data and accessor properties across parsed, detached, adopted,
and child-document forms, including collisions with prototype members.
Apply Trusted Types conversion and violation reporting to report-only eval and Function sinks while allowing unconverted sources when enforcement is absent. Preserve default-policy exceptions and the existing rejection of transformed code-generation sources. Includes report-only execution and queued violation regressions.
Validation: all branch checks passed. Summary [ 132.995s] 18922 tests run: 18922 passed (9 slow), 16 skipped
Expand WPT domain and host templates for configured Unicode labels, nested subdomains and alternate hosts using IDNA output. Leave unknown template keys and non-template response bytes unchanged. Tests exercise response bodies, headers and one-pass request substitutions.
Validation: all branch checks passed. Ran 324 tests in 125.691s; OK
Support remote-context executor pages and dispatcher queues, including atomic FIFO messages, request-header forwarding, CORS and response pipes. The branch includes the minimal shared response/body helpers it needs and does not depend on the iframe-stash branch. Tests cover wire behavior, concurrent queue operations and case selection.
Validation: all branch checks passed. Ran 336 tests in 134.129s; OK
