- introduce process-wide ResourceId, resource handles, and shared metrics
- manage textures through factory-owned control blocks and a weak live registry
- defer final texture destruction until display-time batch work is flushed
- diagnose externally retained textures during Engine shutdown
- migrate texture identity APIs and consumers from Uint32 to ResourceId
- decouple texture memory accounting from the TextureFactory singleton
- replace UITextureViewer callbacks with generation-based weak snapshots
- remove obsolete texture context-reload APIs and loader callback registry
- add registry, identity, memory, restart, and deferred-release tests
- mark Stage 1 complete in the shared-resource architecture plan
- add explicit open, closing, and closed states to the UISceneNode async delivery queue
- reject delivery execution during shutdown and purge retained captures after scene producers join
- reopen the queue cleanly when recreating Engine state in tests
- add regressions for stale deliveries, retained captures, concurrent producers, and Engine restart
- remove the obsolete and unused FrameBuffer context-loss reload API
- simplify redundant namespace qualification in UI tests and ecode declarations
- consolidate completed resource plans into the active ownership architecture
- defer TextureLoader callback removal directly to Stage 1 live-texture observation
- document the requirement to validate legacy lifecycles and prefer removing dead mechanisms
- retain asynchronous HTTP operations until execution or queue disposal
- make HTTP shutdown cancel and join queued and running shared-pool requests
- avoid deadlocks when callbacks clear the HTTP pool
- share atomic cancellation state across request copies
- detect socket creation failures before configuring TCP or UDP sockets
- release partially initialized mbedTLS state after failed handshakes
- replace retained FreeType faces with bounded LRU probe-result caching
- release non-trivial StaticLRU keys when clearing the cache
- resolve the Texture Viewer close icon through the configured icon theme
- add HTTP, TLS, UIWebView fan-out, font descriptor, and LRU regressions
- update resource-refactor prerequisite and ownership planning documents
- Pool-owned HTTP clients stop first.
- The active GL context is made current.
- Scenes are destroyed before batches and resource managers.
- Pending batches explicitly discard vertices and borrowed textures.
- TextLayout cache clears before fonts.
- Framebuffer/vertex managers and textures are released while Renderer/context remain alive.
- ShaderProgramManager is destroyed before Renderer.
- Windows and contexts are destroyed last.
The lifecycle test uncovered and fixed another bug: StaticLRU::clear() retained non-trivial values such as cached shared_ptr<TextLayout> objects. It now releases active values in LRUCache.
Destroy pooled HTTP clients after releasing the pool mutex so joined
callbacks can safely re-enter the global pool.
Add a regression test covering concurrent pool clearing and callback
re-entry. Document the revised texture lifetime architecture and track
the prerequisite bugs discovered during the resource ownership audit.
Inline frequently used scene and UI state accessors to reduce function
call overhead during layout, rendering, and rich-text traversal.
Add string-view numeric conversion support and parse CSS length values
without temporary number or unit strings. Preserve existing string
overloads for compatibility and keep CSS function parsing unchanged.
Add focused parsing coverage and benchmarks. Full-suite profiling showed
substantial reductions in layout invalidation, whitespace traversal, and
CSS length parsing costs.
Resolve standard property definitions and data-attribute classification
when selectors are parsed, avoiding repeated specification lookups and
attribute-name checks during matching.
Fast-path existence-only data selectors without retrieving their values,
while preserving all attribute operator behavior. Add standard-property
coverage and an attribute-focused benchmark showing a 41.7% reduction
in matching time.
Add a fast path that directly evaluates selectors containing one rule,
avoiding combinator traversal and switch overhead for common class, ID,
tag, and pseudo-class selectors.
Move complex selector traversal into a dedicated function and cache rule
counts in selector loops. Add focused matching coverage and document the
Phase 7 benchmark results.
Index class-anchored selectors by one mandatory class hash so widgets
only evaluate rules associated with their own classes instead of
scanning every class-only rule in the global bucket.
Preserve selector correctness by validating the complete rule after
candidate lookup, and retain stylesheet source order across independent
index buckets for equal-specificity cascade resolution.
Update index clearing, copying, marker removal, and style insertion
paths. Add focused candidate coverage and a legacy full-scan benchmark,
showing a 63% lookup-time reduction on a class-heavy stylesheet.
Cache tag, ID, and class hashes in selector rules and widgets to avoid
repeated string comparisons during selector matching.
Store widget class hashes in a single-element SmallVector so the common
zero and one-class cases remain allocation-free. Reorder UINode and
UIWidget members to recover padding, keeping UIWidget at its original
1144-byte size.
Add selector matching benchmarks and regression coverage for class
mutation, compound selectors, and hash cache synchronization. Document
the measured Phase 5 performance and memory results.
Apply @font-face weights to loaded variable fonts, preserve author
font-family names for internal font-face aliases, and re-resolve text fonts
when style or weight changes after initial font selection.
Also updates the font-weight native variant plan to reflect the current
architecture and remaining work around static native weight variants.
Resolve CSS variable values at the points where properties are applied,
inherited, propagated, and used to seed transitions. This prevents raw
var() values from leaking into widget state or transition start/end
values when style attributes, inherited properties, or state-dependent
rules are involved.
Also refresh style definitions when widgets load so selector-dependent
rules are evaluated with the final widget context, and add regression
coverage for inline style vars, inherited vars, parent-state child rules,
tab close opacity, and foreground tint transitions.
Use poll() for POSIX TcpSocket timed connects instead of select().
select() cannot safely handle descriptor values >= FD_SETSIZE, so a
process with many open sockets/resources could fail new HTTPS requests
even when only one socket was being waited on. This showed up in the
HTML compat module when loading request-heavy pages such as old Reddit.
Keep the Windows path on select(), since Winsock does not use nfds as a
POSIX descriptor limit and this code only waits on one socket.
Also initialize HttpConnection::mIsKeepAlive in the TcpSocket-taking
constructor, matching the default constructor and avoiding undefined
connection lifetime state.
Add a regression test that reserves file descriptors past FD_SETSIZE and
verifies a timed localhost TcpSocket connect still succeeds.
- Treat drawable ref "none" as clearing the layer drawable instead of
trying to load it as a drawable/image reference.
- Round the scroll view inner width up before deciding horizontal
scrollbar visibility, avoiding fractional pixel overflow from creating
a bogus horizontal scrollbar.
Preserve shrink-to-fit widths for floated HTML boxes whose CSS width is
auto, instead of letting their own block layout expand them back to the
containing block width. This matches the CSS float model and fixes floated
list-item menus where hover boxes were much wider than their content.
Also separate RichText visual font metrics from CSS line-box metrics. Text
runs now keep native font height for drawing while line layout still uses
CSS line-height, allowing the expected half-leading offset for vertically
centered text in block anchors.
Add CSS box-sizing support for HTML widgets and route CSS-specified
width/height conversion through virtual sizing hooks. Resolve percentage
CSS sizes against the containing block content box, and apply content-box
or border-box conversion consistently across block, flex, grid, table,
and rich text layout paths.
Keep table wrapper width behavior compatible with CSS table layout by
overriding the table width conversion separately, so padded percentage
tables do not overflow their assigned wrapper width.
Add focused regressions for block padding, flex-basis sizing, grid
containers, table containers, and the border rendering cases that depend
on explicit border-box sizing.

Added control over the UISceneNode children and added setHighlightOverRecursive. This allows us to inspect nested UISceneNodes.
Fix hit-box bug when changing display.
