- Replace full editor values with bounded 1024-code-point previews.
- Reuse previews when document identity and revision are unchanged.
- Use proportional column widths and borrowed model strings.
- Add explicit full-value copying with loading-state safeguards.
- Safely defer worker-originated refreshes to the main thread.
- Add regression tests and Inspector allocation benchmarks.
- Document preview behavior and text revision assumptions.
- Build text indexes using a bulk line-length read under one lock scope,
reusing storage and returning the document revision.
- Avoid requesting unused text offsets in the Accessibility Inspector.
- Add cold first-edit/focus benchmarks and regression tests for unqueried
edits, Inspector updates, Unicode lengths, and buffer reuse.
- Document the remaining O(lines) initialization cost and measurements.
Reduce million-line cold edits from ~29.2 ms to ~5.7 ms without changing
allocation counts, class sizes, or dormant-path work.
- Replace global line caches with lazy, per-manager document indexes
- Update affected line lengths without allocations on ordinary edits
- Preserve indexes across muted edits and recover ambiguous nested changes
- Count semantic children without materializing node identities
- Add a 2 ms AT-SPI dispatch budget while preserving backlog wakeups
- Add opt-in AT-SPI/UIA profiling and active performance benchmarks
- Cover shared documents, lifecycle, Unicode and nested-edit regressions
- Document measurements, scalability limits and native-host follow-ups
Text:
- Ranged text access in code points (length, range, line bounds) that
never copies more than requested, plus a text revision (document UUID
and modification) so UIA and macOS cache their UTF-16 copies.
- Report document edits as exact change records, up to four per widget
and frame, then collapse to one whole-text change. Resets, loads and
document swaps report a whole-text change.
- The removed text is available only while an edit is being notified
(TextDocument::getNotifiedRemovedText()); DocumentContentChange stays
{ range, text }, so queued records (LSP) copy nothing extra.
- Suppressed text changes are keyed by node ref, so a document shared
with another window still reports its edits.
- UITextView reports NameChanged; UITextInput overrides onTextChanged()
to report ValueChanged.
Relations, live regions and shortcuts:
- aria-labelledby, aria-describedby and aria-live (API and CSS). Ids a
client has read are remembered; renaming, adding or removing their
widgets notifies the dependents. setId() copies the old id only when
it is remembered.
- Live regions and UISceneNode::announceForAccessibility(). A newer
change from the same widget replaces its pending announcement, and
hidden sources are dropped.
- Menu item shortcuts (std::string text and key) exposed as AT-SPI key
bindings, the UIA accelerator key and macOS command characters.
- ScrollTo for anything inside a scroll view
(UIScrollView::scrollIntoView()). Icon-only buttons are named from
their tooltip.
Dormant path (no client attached):
- Widget notifications are inline: one relaxed atomic load of a
process-wide count of active root scenes, no call.
- Scene destruction and scene or host changes never create a manager.
Without a client, notify() queues nothing and widget deletion does
not register parents to announce it. While only the root has an
identity, deletion skips the ancestor walk unless a remembered
relation target may be affected.
- When the last client disconnects, model-view sources release their
queried rows. Persistent handles count their registrations, so
handles held elsewhere survive (PersistentModelIndex::release()).
- Spin boxes no longer hide their input explicitly, and
AccessibilityProperties shrinks from 144 to 136 bytes.
Backends:
- AT-SPI: object:announcement, word and line granularity, ranged
reads, SetTextContents reported as its minimal diff. Watch
disconnects per client (NameOwnerChanged arg0 plus a non-blocking
NameHasOwner check) instead of for every bus name. Without a scene
thread pool, initialize on a detached thread that shares ownership,
so teardown never waits on D-Bus timeouts.
- UIA: notification events (resolved at runtime, Windows 10 1709+),
text ranges served from the revision cache, and a per-frame provider
drain that skips the lock when nothing is queued.
- macOS: announcements, a UTF-16 text cache per revision, and command
key attributes.
- EEPP_ACCESSIBILITY_TRACE=1 logs client activity transitions.
Fixes:
- UICodeEditor::isType() no longer dispatches to a subclass's
getType(), so a UITextEdit is a code editor again.
- ecode: dropped files open only in document editors, not in other
code editors such as a commit message box.
Tools, tests and docs:
- Widget inspector: role names, shortcut, relation and live rows, and
an accessibility audit (unnamed controls, broken relations).
- Accessibility example: live status, an icon-only button, and edit and
reset actions that test_atspi.py checks end to end.
- Regression tests for text records, relations, live regions,
disconnect and reconnect, scene lifecycle and id changes.
- Add the AccessibilityDormant benchmark (C++ new/new[] counted on the
measuring thread) and benchmark_accessibility_dormant.py, which fails
on missing measurements and compares against other builds with
--compare LABEL=PATH.
- Document the dormant-path rules, what survives a disconnection, and
the remaining platform limitations.
