Publish one layout-only snapshot after page readiness and delay for --eval and --eval-file. Keep geometry getters on the last published snapshot during script execution.
Make geometry, input and observers read the latest published layout without
cold-start or invalidation-triggered layout. Only screenshot, screencast and
PDF output can build and publish a new tree.
Connect WebDriver page screenshots to the shared output pipeline, explain how
to initialize layout in errors, and migrate fixtures to explicit publication.
Remove obsolete read policies and embedded-frame completeness metadata.
Per-Window length counters cannot shrink after traversal and branching, and
leave retained sibling History objects stale. Give each traversable one
ordered history and cursor with stable step, browsing context, and Document
identities. All History getters read that state; Navigation entries remain
Document views.
Route push, replace, traversal, and pruning through the shared model. Carry
browser positions or renderer snapshots into new Documents and publish
committed mutations through the Page owner-action FIFO. Remove cached length
adjustments and DOM-order traversal guesses. Preserve srcdoc identity when
only its parent's URL changes.
Keep reset callback pushes in both renderer and browser history, and prune
discarded sibling Navigation entries when forward steps are removed.
Validation: cargo fmt --all; workspace all-targets/all-features Clippy with
warnings denied; cargo nextest run --no-fail-fast (18,501 passed, 14 skipped);
12 targeted Chromium/Moli state and length comparisons; frontend differential
1,020/1,020 matches, all 5,259 observed frames matching, with zero retries.
Carry raw response header values through fetch, caches, redirects,
renderer delivery, workers, and protocol records. Convert explicitly
at WebIDL and protocol text boundaries while preserving opaque bytes.
Keep legacy CacheStorage and service worker metadata readable, and
advance the HTTP cache format for raw header values.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- cargo nextest run --no-fail-fast
Restore original headers on redirect while preserving current-hop overrides
for authentication retries and keeping Network event identity intact.
Preserve raw BiDi Cookie, Set-Cookie, and extra header values through page,
navigation, and worker policies. Apply CDP's last-value behavior for duplicate
request header names.
Add coverage for header bytes, redirects, authentication, and event sequences.
Carry RequestHeaders through navigation, Fetch/XHR, workers, redirects and auth,
with explicit Unicode and ByteString conversions at protocol and WebIDL boundaries.
Share the raw curl header list with WebSocket transport and decode binary response
headers without UTF-8 replacement. Keep header memory charging concrete.
Cover opaque values, UTF-8 overrides, duplicates, redirect/auth continuation and
WebSocket handshakes with byte-level regression tests.
Keep request origin independent of URL resolution and referrer context,
including local blob fetches and inherited or sandboxed srcdoc documents.
Reject missing browser origins at the resource client boundary and retain
one Request across Service Worker redirects and network fallback.
Cover dispatch rejection, wire Origin/Cookie headers, memory-cache
partitioning and preserved Service Worker request metadata.
Validation: workspace fmt and Clippy passed; Nextest passed 17,517 tests
with 13 existing skips. Renderer test debug symbols were disabled to fit
available build memory; tests and debug assertions were unchanged.
Remove the Date/Intl wrappers, custom date parser and per-Page replay state. Keep exclusive locale/timezone ownership in a process controller and refresh existing Page and Worker isolates through generation-bound notifications and observation boundaries, including nested Inspector pauses.
Release claims on session/target/context retirement, retain native coercion and locale matching, and cover lifecycle restoration with Rust, BiDi and process-isolated CDP regressions.
Carry foreground/background selection through renderer and protocol so auxiliary targets are activated independently of navigation. Match trusted input policy for platform modifiers, Shift, Alt, and window.open while preventing synthetic modified clicks from creating tab-unders.
Apply one absolute deadline across response headers, streaming raw bodies, page creation, and later readiness waits. Report the active timeout phase without extending the caller's budget and reject raw documents from Page APIs before an unusable body can stall.
Give CLI fetch failures a stable two-line Error/Reason presentation while retaining full anyhow chains for non-fetch failures, including raw-document page-wait errors.
Split screenshot and screencast capture contracts, publish one shared visual resource generation, and collect CSS image references during the real layout traversal. Add asynchronous publication and multi-session screencast regressions.
