# Fixes Applied to Patch Series
|
||||
|
||||
All fixes applied to `/tmp/emacs-doom-review/patches/` on 2026-03-04.
|
||||
|
||||
---
|
||||
|
||||
## FIX 1 — 0002: Revert em-dash → triple-dash in windowWillResize strings
|
||||
|
||||
**File:** `0002-ns-implement-buffer-accessibility-element.patch`
|
||||
|
||||
The `windowWillResize:` hunk incorrectly changed the window-resize title separator from
|
||||
em-dash (U+2014, ` — `) to triple-dash (` --- `) in:
|
||||
- `strstr (t, " — ")` — used to strip the size suffix when resizing begins
|
||||
- `esprintf (size_title, "%s — (%d × %d)", …)` — used to format the title
|
||||
|
||||
Both `-` lines were converted to context (` ` prefix) and the corresponding `+` lines
|
||||
were removed. The hunk header counts remained unchanged (13,13) since the net effect
|
||||
on old/new line counts is zero.
|
||||
|
||||
---
|
||||
|
||||
## FIX 2 — 0007: Remove spurious ns_ax_face_is_selected from commit message
|
||||
|
||||
**File:** `0007-ns-announce-overlay-completions-to-VoiceOver.patch`
|
||||
|
||||
The ChangeLog entry for `ns_ax_face_is_selected` was removed from the commit message:
|
||||
```
|
||||
* src/nsterm.m (ns_ax_face_is_selected): New static function; matches
|
||||
'current', 'selected', 'selection' in face symbol names.
|
||||
```
|
||||
This function does not exist in the diff — the actual function is
|
||||
`ns_face_name_matches_selected_p` (introduced in patch 0000/0001).
|
||||
|
||||
---
|
||||
|
||||
## FIX 3 — All patches: Renumber series for proper separation
|
||||
|
||||
The patches were renumbered to reflect two independent series:
|
||||
|
||||
| File | Before | After | Series |
|
||||
|--------|---------------|---------------|-------------------|
|
||||
| 0000 | [PATCH 1/9] | [PATCH 1/1] | Zoom (standalone) |
|
||||
| 0001 | [PATCH 2/9] | [PATCH 1/8] | VoiceOver |
|
||||
| 0002 | [PATCH 3/9] | [PATCH 2/8] | VoiceOver |
|
||||
| 0003 | [PATCH 4/9] | [PATCH 3/8] | VoiceOver |
|
||||
| 0004 | [PATCH 5/9] | [PATCH 4/8] | VoiceOver |
|
||||
| 0005 | [PATCH 6/9] | [PATCH 5/8] | VoiceOver |
|
||||
| 0006 | [PATCH 7/9] | [PATCH 6/8] | VoiceOver |
|
||||
| 0007 | [PATCH 8/9] | [PATCH 7/8] | VoiceOver |
|
||||
| 0008 | [PATCH 9/9] | [PATCH 8/8] | VoiceOver |
|
||||
|
||||
---
|
||||
|
||||
## FIX 4 — 0008: Refactor goto to nested if
|
||||
|
||||
**File:** `0008-ns-announce-child-frame-completions-to-VoiceOver.patch`
|
||||
|
||||
**Note:** The task description incorrectly named file 0007; the goto is in 0008.
|
||||
|
||||
In `postAccessibilityNotificationsForFrame:`, the overlay completion scan used a
|
||||
`goto skip_overlay_scan;` pattern. Refactored to a standard nested `if` block:
|
||||
|
||||
Before (in diff):
|
||||
```c
|
||||
if (!MINI_WINDOW_P (w) || didTextChange)
|
||||
goto skip_overlay_scan;
|
||||
|
||||
int selected_line = -1;
|
||||
NSString *candidate = ns_ax_selected_overlay_text (…);
|
||||
if (candidate)
|
||||
{ … }
|
||||
|
||||
skip_overlay_scan:
|
||||
/* --- Cursor moved … */
|
||||
```
|
||||
|
||||
After (in diff):
|
||||
```c
|
||||
if (MINI_WINDOW_P (w) && !didTextChange)
|
||||
{
|
||||
int selected_line = -1;
|
||||
NSString *candidate = ns_ax_selected_overlay_text (…);
|
||||
if (candidate)
|
||||
{ … }
|
||||
}
|
||||
/* --- Cursor moved … */
|
||||
```
|
||||
|
||||
The extended comment explaining the `didTextChange` guard was preserved. The inner
|
||||
body code is restored to its original indentation level. Hunk header updated from
|
||||
`+9609,49` to `+9609,48` (one fewer net added line).
|
||||
|
||||
---
|
||||
|
||||
## FIX 5 — 0006: Remove "Block-style cursors" from Known Limitations
|
||||
|
||||
**File:** `0006-doc-add-VoiceOver-section-to-macOS-appendix.patch`
|
||||
|
||||
Removed the `@item` bullet from the Known Limitations `@itemize`:
|
||||
```texinfo
|
||||
@item
|
||||
Block-style cursors are handled correctly: character navigation
|
||||
announces the character at the cursor position, not the character
|
||||
before it.
|
||||
```
|
||||
This is a feature, not a limitation. The hunk header was updated from
|
||||
`+273,82` to `+273,78` (4 fewer added lines).
|
||||
|
||||
---
|
||||
|
||||
## FIX 6 — 0001: Spell out "AT" in commit message
|
||||
|
||||
**File:** `0001-ns-add-accessibility-base-classes-and-helpers.patch`
|
||||
|
||||
In the ChangeLog entry for `syms_of_nsterm`:
|
||||
|
||||
Before: `set non-nil automatically when an AT is detected at startup.`
|
||||
After: `set non-nil automatically when an assistive technology (AT) is detected at startup.`
|
||||
|
||||
---
|
||||
|
||||
## FIX 7 — 0005: Spell out "AT" in commit message
|
||||
|
||||
**File:** `0005-ns-wire-accessibility-into-EmacsView-and-redisplay.patch`
|
||||
|
||||
**Result: No-op.** The commit message of patch 0005 (lines before the `---` separator)
|
||||
contains no "AT" abbreviation. The "AT" occurrences found by grep are in code comments
|
||||
within the diff body (not the commit message proper). No changes were made.
|
||||
|
||||
---
|
||||
|
||||
## FIX 8 — 0006: Remove spurious @xref note from commit message
|
||||
|
||||
**File:** `0006-doc-add-VoiceOver-section-to-macOS-appendix.patch`
|
||||
|
||||
Removed the sentence "Use @xref for cross-reference at sentence start." from the
|
||||
ChangeLog entry. This referenced an `@xref` that does not appear in the patch.
|
||||
|
||||
Before:
|
||||
```
|
||||
enabled, and known limitations. Use @xref for cross-reference at
|
||||
sentence start. Correct description of ns-accessibility-enabled
|
||||
```
|
||||
After:
|
||||
```
|
||||
enabled, and known limitations. Correct description of ns-accessibility-enabled
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## FIX 9 — 0001: Update stub comment reference
|
||||
|
||||
**File:** `0001-ns-add-accessibility-base-classes-and-helpers.patch`
|
||||
|
||||
In the stub `@implementation EmacsAccessibilityBuffer (InteractiveSpans)`:
|
||||
|
||||
Before: `/* Stub: full implementation added in patch 0004. */`
|
||||
After: `/* Stub: full implementation in the following patch. */`
|
||||
|
||||
This avoids a hard-coded patch number that may shift if the series is reordered.
|
||||
|
||||

|
||||
|
||||
## FIX 10 — 0000: Style nits
|
||||
|
||||
**File:** `0000-ns-integrate-with-macOS-Zoom-for-cursor-tracking.patch`
|
||||
|
||||
### a) Double blank line before `#ifdef NS_IMPL_COCOA`
|
||||
|
||||
In the large inserted block starting at `-1081,6 +1086,N`, an extra blank `+` line
|
||||
preceded `+#ifdef NS_IMPL_COCOA`, creating a triple blank gap. The extra `+\n` line
|
||||
was removed. Hunk header updated from `+1086,293` to `+1086,292`.
|
||||
|
||||
### b) Unnecessary block scope in `ns_draw_window_cursor`
|
||||
|
||||
The Zoom integration block used a gratuitous `{ … }` scope wrapper:
|
||||
```c
|
||||
{
|
||||
EmacsView *view = FRAME_NS_VIEW (f);
|
||||
if (view && on_p && active_p)
|
||||
{ … }
|
||||
}
|
||||
```
|
||||
Removed the outer braces and dedented the contents by one level:
|
||||
```c
|
||||
EmacsView *view = FRAME_NS_VIEW (f);
|
||||
if (view && on_p && active_p)
|
||||
{ … }
|
||||
```
|
||||
Hunk header updated from `+3559,45` to `+3559,43` (2 fewer added lines).
|
||||
|
||||
---
|
||||
|
||||
## FIX 11 — 0008: Remove spurious blank line in announceChildFrameCompletion
|
||||
|
||||
**File:** `0008-ns-announce-child-frame-completions-to-VoiceOver.patch`
|
||||
|
||||
Removed the blank line between the opening `{` and the first comment in the
|
||||
`announceChildFrameCompletion` method body. Hunk header updated from
|
||||
`+12991,156` to `+12991,155`.
|
||||
|
||||

|
||||
|
||||
## Verification

||||
|
||||
All 9 patch files pass post-fix verification:
|
||||
- All Subject: lines present with correct [PATCH N/M] numbering
|
||||
- All @@ hunk headers syntactically valid
|
||||
- No `goto skip_overlay_scan` or `skip_overlay_scan:` label remaining
|
||||
- No triple-dash in functional window-resize strings
|
||||
- No `ns_ax_face_is_selected` in 0007 commit message

## Review Summary
|
||||
|
||||
**Overall verdict: READY WITH MINOR FIXES**
|
||||
|
||||
The series has matured well through six rounds. Architecture is sound, threading model is correct, performance claims are supportable. Two items block upstream submission:
|
||||
|
||||
### Must fix
|
||||
|
||||
**Patch 0002** — Contains an unrelated functional change: the window-resize title string changes `strstr(t, " — ")` and `esprintf(..., "%s — ...")` from Unicode em-dash to triple-dash `---`. This is a behavioral change to non-accessibility code embedded in an accessibility patch. A maintainer will catch it immediately.
|
||||
|
||||
**Patch 0007** — The commit message claims to introduce `ns_ax_face_is_selected` as a new function, but no such function appears in the diff. The actual code calls `ns_face_name_matches_selected_p` from patch 0000. The ChangeLog entry must be corrected.
|
||||
|
||||
### Structural (must fix before submission)
|
||||
|
||||
**[PATCH 1/9] numbering** — All nine patches are numbered as one series, but the README says 0000 is independent of 0001–0008. For emacs-devel submission, either add a `[PATCH 0/9]` cover letter explaining the split, or submit 0000 separately as `[PATCH 1/1]`.
|
||||
|
||||
### Notable nits (fix recommended)
|
||||
|
||||
- `goto skip_overlay_scan` in patch 0007 — unusual in Emacs C; Stefan Monnier will likely ask for a nested `if` instead
|
||||
- "Known Limitations" fifth bullet in patch 0006 ("Block-style cursors are handled correctly...") is a feature, not a limitation
|
||||
- "AT" abbreviation in commit messages — spell out "assistive technology"
|
||||
- Patch 0006 commit message references an `@xref` that isn't there
|
||||
|
||||
### What's clean (no action needed)
|
||||
|
||||
Patches 0003, 0004, 0005 are LGTM. The threading model (AX thread → dispatch_sync to main), the `@synchronized` cache guards, `block_input`/`unblock_input` specpdl protection, GNUstep exclusion, and performance claims all check out.
|
||||
p` TTL caching with `CFAbsoluteTimeGetCurrent()` is
|
||||
well motivated; the 1-second TTL justification is documented clearly.
|
||||
- `ns_face_name_matches_selected_p` using `strstr` on face symbol names
|
||||
is an accepted heuristic; the comment acknowledges it.
|
||||
- specpdl unwind protection is correct throughout.
|
||||
- `ns_zoom_find_child_frame_candidate`: inside the FOR_EACH_FRAME body,
|
||||
`block_input()` is called before `SPECPDL_INDEX()`. In practice this
|
||||
is safe (SPECPDL_INDEX cannot fail), but the canonical Emacs ordering
|
||||
is SPECPDL_INDEX -> record_unwind -> block_input. Patch 0008 later
|
||||
reverses this order in `ns_ax_buffer_text` with an explanatory comment;
|
||||
0000 is left inconsistent. Nit only.
|
||||
- Double blank line before `#ifdef NS_IMPL_COCOA` at the top of the new
|
||||
block (~line 93 of the diff). GNU Emacs style uses a single blank
|
||||
line between top-level definitions.
|
||||
- Block scope `{ EmacsView *view = ...; }` in `ns_draw_window_cursor` is
|
||||
unnecessary (no outer `view` in scope at that point); the extra braces
|
||||
can be removed.
|
||||
|
||||
**Verdict: LGTM with nits** -- fix numbering before submission; the
|
||||
code is otherwise clean.
|
||||
|
||||

|
||||
|
||||
### 0001: Add accessibility base classes and helpers [PATCH 2/9]
|
||||
|
||||
**Subject / commit message**
|
||||
Correct format. The commit message abbreviates "AT" for "assistive
|
||||
technology" -- spell it out for an emacs-devel audience.
|
||||
|
||||
**Code quality**
|
||||
|
||||
- GC safety analysis on `lispWindow` is thorough and correct.
|
||||
- `@synchronized (self)` guards on visibleRuns/lineStartOffsets are
|
||||
correct; they protect against concurrent reads from the AX server
|
||||
thread while the main thread rebuilds the cache.
|
||||
- `ns_ax_buffer_text` correctly uses `Fbuffer_substring_no_properties`
|
||||
instead of raw `BUF_BYTE_ADDRESS` to handle the buffer gap. ✓
|
||||
- `Fget_char_property (pos, Qinvisible, Qnil)` with Qnil meaning the
|
||||
current buffer is correct after `set_buffer_internal_1(b)`. ✓
|
||||
- `TEXT_PROP_MEANS_INVISIBLE` correctly mirrors xdisp.c logic. ✓
|
||||
- The stub `@implementation EmacsAccessibilityBuffer (InteractiveSpans)`
|
||||
has a comment reading "full implementation added in patch 0004". Once
|
||||
the series numbering is resolved this should say "in the following
|
||||
patch" or match the final [PATCH N/M] numbers.
|
||||
|
||||
**Verdict: LGTM with nits.**
|
||||
|
||||
---
|
||||
|
||||
### 0002: Implement buffer accessibility element [PATCH 3/9]
|
||||
|
||||
**SERIOUS ISSUE -- unrelated functional change**
|
||||
|
||||
Deep in the diff, in the context of `windowWillResize:toSize:`, the patch
|
||||
changes:
|
||||
|
||||
```diff
|
||||
- char *pos = strstr (t, " \xe2\x80\x94 ");
|
||||
+ char *pos = strstr (t, " --- ");
|
||||
...
|
||||
- esprintf (size_title, "%s \xe2\x80\x94 (%d x %d)", old_title, cols, rows);
|
||||
+ esprintf (size_title, "%s --- (%d x %d)", old_title, cols, rows);
|
||||
```
|
||||
|
||||
This replaces a Unicode em-dash (U+2014) with three ASCII hyphens in the
|
||||
*functional* window-resize title string. This:
|
||||
|
||||
- Is unrelated to accessibility.
|
||||
- Changes the visual appearance of the resize title bar.
|
||||
- Must be in its own commit (with its own ChangeLog entry and
|
||||
justification) or reverted. A maintainer will reject the patch if
|
||||
they spot this.
|
||||
|
||||
All other content in this patch is correct:
|
||||
|
||||
- `@synchronized (self)` in `invalidateTextCache` correctly releases
|
||||
Objective-C objects under the lock; `invalidateInteractiveSpans` is
|
||||
called outside the lock to avoid mutex inversion. ✓
|
||||
- Binary search in `accessibilityIndexForCharpos:` and
|
||||
`charposForAccessibilityIndex:` is correct; the O(1) ASCII fast-path
|
||||
is well-motivated and the comment explains why it matters. ✓
|
||||
- `setAccessibilitySelectedTextRange:` correctly deactivates the mark
|
||||
(with explanatory comment about VoiceOver word-boundary hints). ✓
|
||||
- `dispatch_async` for setters (no return value needed) vs.
|
||||
`dispatch_sync` for getters (return value required) is the correct
|
||||
pattern throughout. ✓
|
||||
- `accessibilityStyleRangeForIndex:` is the only getter without its own
|
||||
main-thread check; it relies on two sub-calls that each dispatch
|
||||
individually. Correct but two round-trips instead of one. Minor nit.
|
||||
|
||||
**Verdict: Needs work** -- remove the window title em-dash change.
|
||||
|
||||
---
|
||||
|
||||
### 0003: Add AX notifications and mode-line element [PATCH 4/9]
|
||||
|
||||
**Subject / commit message**
|
||||
Correct. ChangeLog entries are detailed and accurate.
|
||||
|
||||
**Code quality**
|
||||
|
||||
- `postTextChangedNotification:` single-character fast path (grab the
|
||||
inserted char for `AXTextChangeValue`) is a useful optimization.
|
||||
- `postFocusedCursorNotification:direction:granularity:markActive:
|
||||
oldMarkActive:` granularity reasoning -- omit for char moves to prevent
|
||||
block-cursor double-speech -- matches documented WebKit behaviour. ✓
|
||||
- `postCompletionAnnouncementForBuffer:point:` four-level fallback chain
|
||||
(completion--string -> mouse-face -> completions-highlight overlay ->
|
||||
line text) is comprehensive.
|
||||
- `[ws mutableCopy]` / `[trims release]` in the word-announcement path
|
||||
is correct MRC. ✓
|
||||
- `EmacsAccessibilityModeLine` returns `NSAccessibilityStaticTextRole`;
|
||||
`accessibilityValue` delegates to `ns_ax_mode_line_text`. Correct.
|
||||
|
||||
**Verdict: LGTM.**
|
||||
|
||||
---
|
||||
|
||||
### 0004: Add interactive span elements for Tab [PATCH 5/9]
|
||||
|
||||
**Subject / commit message**
|
||||
Correct.
|
||||
|
||||
**Code quality**
|
||||
|
||||
- `ns_ax_scan_interactive_spans` priority ordering (widget > button >
|
||||
follow-link > org-link > completion > keymap-overlay) is a reasonable
|
||||
policy; documented in the function comment.
|
||||
- Skip-to-next-change logic uses the minimum of per-property change
|
||||
points: O(properties * log(buffer)) rather than O(chars). ✓
|
||||
- `EmacsAccessibilityInteractiveSpan.isAccessibilityFocused` reads
|
||||
`pb.cachedPoint` (a plain `ptrdiff_t`) without `@synchronized`. This
|
||||
is safe because `cachedPoint` is only written on the main thread and
|
||||
the ivar is machine-word aligned (naturally atomic on ARM64/x86-64).
|
||||
Acceptable; a brief comment noting this would be welcome.
|
||||
- `setAccessibilityFocused:` correctly uses `dispatch_async` with the
|
||||
Lisp_Object-captured-by-value comment. ✓
|
||||
- Removes the stub `@implementation` from patch 0001 cleanly. ✓
|
||||
|
||||
**Verdict: LGTM.**
|
||||
|
||||
---
|
||||
|
||||
### 0005: Wire accessibility into EmacsView and redisplay [PATCH 6/9]
|
||||
|
||||
**Subject / commit message**
|
||||
Correct.
|
||||
|
||||
**Code quality**
|
||||
|
||||
- Re-entrance guard (`accessibilityUpdating`) is placed correctly at the
|
||||
start of `postAccessibilityUpdates`. ✓
|
||||
- `ns_update_accessibility_state` uses `AXIsProcessTrustedWithOptions`
|
||||
with `kAXTrustedCheckOptionPrompt: @NO` -- does not prompt the user. ✓
|
||||
- `(__bridge id)` and `(__bridge CFDictionaryRef)` casts in MRC context
|
||||
are correct for toll-free bridging (no ownership transfer). ✓
|
||||
- `com.apple.accessibility.api` distributed notification is the standard
|
||||
(if undocumented) mechanism used by WebKit et al. ✓
|
||||
- Window-switch detection via `lastSelectedWindow` comparison is clean.
|
||||
- `accessibilityBoundsForRange:` / `accessibilityFrameForRange:` / the
|
||||
legacy `accessibilityAttributeValue:forParameter:` delegation chain is
|
||||
complete and handles both modern and pre-10.10 AX API callers. ✓
|
||||
- `postAccessibilityUpdates` calls `rebuildAccessibilityTree` before the
|
||||
per-element notification loop when the tree is stale, with a clear
|
||||
comment explaining why (cannot diff state after fresh elements are
|
||||
created). ✓
|
||||
|
||||
**Verdict: LGTM.**
|
||||

### 0006: doc: Add VoiceOver section to macOS appendix [PATCH 7/9]
|
||||
|
||||
**Texinfo structure**
|
||||
|
||||
- `@node VoiceOver Accessibility` inserted between `Mac / GNUstep Events`
|
||||
and `GNUstep Support`. Menu entry correctly added. ✓
|
||||
- `@cindex`, `@vindex`, `@itemize @bullet`, `@subheading` all used
|
||||
correctly. ✓
|
||||
- `@section` title "VoiceOver Accessibility (macOS)" is appropriate for
|
||||
the macOS appendix.
|
||||
|
||||
**Content issue**
|
||||
|
||||
In the "Known Limitations" `@itemize`, the fifth bullet reads:
|
||||
|
||||
Block-style cursors are handled correctly: character navigation
|
||||
announces the character at the cursor position, not the character
|
||||
before it.
|
||||
|
||||
This is not a limitation -- it is a correctness feature. It does not
|
||||
belong in a "Known Limitations" section. Remove this bullet or move it
|
||||
to the main feature description above.
|
||||
|
||||
**Commit message note**
|
||||
|
||||
The commit message says "Use @xref for cross-reference at sentence start"
|
||||
but no `@xref` appears in the added Texinfo. The note is stale from a
|
||||
previous revision; remove it or add the intended @xref.
|
||||
|
||||
**Verdict: LGTM with nits** -- fix the Known Limitations bullet; clean up
|
||||
the @xref note in the commit message.

### 0007: Announce overlay completions to VoiceOver [PATCH 8/9]
|
||||
|
||||
**SERIOUS ISSUE -- commit message describes non-existent function**
|
||||
|
||||
The commit message states:
|
||||
|
||||
* src/nsterm.m (ns_ax_face_is_selected): New static function; matches
|
||||
'current', 'selected', 'selection' in face symbol names.
|
||||
|
||||
No function named `ns_ax_face_is_selected` appears anywhere in this
|
||||
patch. The actual code calls `ns_face_name_matches_selected_p`, which
|
||||
was introduced in patch 0000. The commit message must be corrected to
|
||||
remove this spurious ChangeLog entry. A maintainer applying the patch
|
||||
would immediately notice the claimed function does not appear in the diff.
|
||||
|
||||
**Code quality**
|
||||
|
||||
- `ns_ax_selected_overlay_text` uses `SDATA` for the newline scan and
|
||||
correctly notes the data pointer is used only before Lisp calls that
|
||||
could trigger GC. ✓
|
||||
- Stack-allocated `line_starts[512]` / `line_ends[512]` is safe given
|
||||
the vertico-count upper bound and the 512-line cap. ✓
|
||||
- `BUF_CHARS_MODIFF` (not `BUF_MODIFF`) now gates `ValueChanged`; the
|
||||
reason (text-property-only changes from font-lock / Vertico prompt
|
||||
bump BUF_MODIFF but not BUF_CHARS_MODIFF) is well-explained. ✓
|
||||
- Separate `if` for `BUF_OVERLAY_MODIFF` (not `else if`) correctly
|
||||
handles frameworks that bump both counters in one command cycle. ✓
|
||||
- Removing `ensureTextCache` from the cursor-moved branch prevents the
|
||||
O(visible-buffer-text) rebuild cost on every keystroke. ✓
|
||||
- `goto skip_overlay_scan` is unusual in Emacs C code. GNU Emacs does
|
||||
use goto for error exits, but using it to skip over a block is more
|
||||
readable as a nested `if (!MINI_WINDOW_P (w) && !didTextChange)`.
|
||||
Stefan Monnier is likely to request a refactor here.
|
||||
- `block_input` / `record_unwind_protect_void` ordering in
|
||||
`ns_ax_buffer_text` is corrected and documented. ✓
|
||||
- Em-dash to `---` conversions in *comments* are cosmetic cleanup;
|
||||
acceptable (unlike the functional string changes in patch 0002).
|
||||
|
||||
**Verdict: Needs work** -- fix the commit message; consider refactoring
|
||||
the goto.

### 0008: Announce child frame completions to VoiceOver [PATCH 9/9]
|
||||
|
||||
**Subject / commit message**
|
||||
Correct and detailed. ChangeLog entries accurately describe all changes.
|
||||
|
||||
**Code quality**
|
||||
|
||||
- `voiceoverSetPoint` flag design (set in `setAccessibilitySelectedText
|
||||
Range:`, consumed and reset in the next notification cycle) is correct
|
||||
and clean. ✓
|
||||
- `singleLineMove` adjacency detection (NSRange boundary comparison) is
|
||||
package-agnostic; no evil/doom/spacemacs-specific code. ✓
|
||||
- `childFrameLastBuffer` stored as `BVAR(b, name)` (an interned symbol,
|
||||
always reachable from obarray) rather than a raw buffer pointer is the
|
||||
correct GC-safe approach. The comment explaining this is clear. ✓
|
||||
- `childFrameLastCandidate` as a `char *` with `xstrdup`/`xfree` is
|
||||
correct C memory management; freed in `dealloc`. ✓
|
||||
- `postEchoAreaAnnouncementIfNeeded` reads `echo_area_buffer[0]` directly
|
||||
with a comment explaining why `with_echo_area_buffer` is not used.
|
||||
The `minibuf_level == 0` guard is correct. ✓
|
||||
- Re-entrance guard comment correctly notes `announceChildFrameCompletion`
|
||||
makes Lisp calls that can trigger redisplay; the guard is placed before
|
||||
the call. ✓
|
||||
- `childFrameCompletionActive` + child-frame-still-visible check for
|
||||
restoring VoiceOver focus after popup close is clean. ✓
|
||||
- `postFocusedCursorNotification:` updated to omit direction/granularity
|
||||
for discontiguous jumps (let VoiceOver determine what to read) matches
|
||||
the new reasoning about org-agenda blank-line gaps. ✓
|
||||
- NEWS entry upgraded from `---` to `+++` now that documentation exists
|
||||
(added in patch 0006). ✓
|
||||
- Minor: `announceChildFrameCompletion` has a spurious blank line between
|
||||
the opening `{` and the first comment. Cosmetic only.
|
||||
|
||||
**Verdict: LGTM with nits.**
|
||||

||||
|
||||
## Cross-Cutting Issues
|
||||
|
||||
### 1. Patch numbering inconsistency (structural -- must fix)
|
||||
|
||||
All nine patch files carry [PATCH 1/9]-[PATCH 9/9], implying a single
|
||||
series. The README documents 0000 and 0001-0008 as *independent*. For
|
||||
upstream submission via git-send-email, either:
|
||||
|
||||
- Treat all nine as one series with a [PATCH 0/9] cover letter; or
|
||||
- Separate 0000 into its own submission ([PATCH 1/1]) and renumber the
|
||||
VoiceOver series [PATCH 1/8]-[PATCH 8/8].
|
||||
|
||||
### 2. Em-dash conversion in functional code (serious -- must fix in 0002)
|
||||
|
||||
Em-dash to triple-dash conversions in *comments* (patches 0007, 0008)
|
||||
are acceptable style cleanup. The same conversion in *functional string
|
||||
literals* in patch 0002 (`strstr` / `esprintf` window title code) is a
|
||||
behavioral change that does not belong in an accessibility patch.
|
||||
|
||||
### 3. block_input ordering inconsistency (nit)
|
||||
|
||||
Patches 0001-0006 use `SPECPDL_INDEX -> record_unwind -> block_input`.
|
||||
Patch 0008 (and a targeted fix in 0007) adopt `block_input -> record_unwind`
|
||||
and document why. Both orderings are safe in practice, but the series
|
||||
leaves them inconsistent across the added functions.
|
||||
|
||||
### 4. "AT" abbreviation in commit messages (nit)
|
||||
|
||||
Patches 0001 and 0005 use "AT" for "assistive technology" in commit
|
||||
messages without expanding it. Spell it out on first use.
|
||||
|
||||
### 5. Stub comment reference to "patch 0004" (nit)
|
||||
|
||||
The stub `@implementation EmacsAccessibilityBuffer (InteractiveSpans)` in
|
||||
patch 0001 says "full implementation added in patch 0004". Once the
|
||||
series numbering is finalised, update this to match the actual [PATCH N]
|
||||
number, or change it to "the following patch."
|
||||
|
||||
### 6. Threading model assessment
|
||||
|
||||
The dispatch_sync-to-main pattern for all AX getter methods is correct
|
||||
and matches WebKit's approach. The dispatch_async-for-setters pattern
|
||||
is correct (no return value needed). The @synchronized blocks on the
|
||||
shared cache are correctly scoped. The re-entrance guard in
|
||||
`postAccessibilityUpdates` is correctly placed. No threading issues
|
||||
found.
|
||||
|
||||
### 7. GNUstep exclusion
|
||||
|
||||
All new code is within `#ifdef NS_IMPL_COCOA` guards. GNUstep is
|
||||
correctly excluded. ✓
|
||||
|
||||
### 8. Performance claims
|
||||
|
||||
- O(log n) index lookups via binary search on visible runs: correct. ✓
|
||||
- O(log L) line queries via precomputed lineStartOffsets: correct. ✓
|
||||
- BUF_MODIFF gating (not BUF_CHARS_MODIFF) for cache validity: correct
|
||||
and thoroughly justified. ✓
|
||||
- Zero overhead when `ns_accessibility_enabled` is nil: verified by
|
||||
TESTING.txt item 14. ✓
|
||||

## Verdict
|
||||
|
||||
| Patch | Files | Status |
|
||||
|-------|-------|--------|
|
||||
| 0000 | nsterm.h, nsterm.m, NEWS | **LGTM with nits** -- fix numbering; minor style nits |
|
||||
| 0001 | nsterm.h, nsterm.m | **LGTM with nits** -- spell out "AT"; update stub comment |
|
||||
| 0002 | nsterm.m | **Needs work** -- remove em-dash/triple-dash change from window-resize string |
|
||||
| 0003 | nsterm.m | **LGTM** |
|
||||
| 0004 | nsterm.m | **LGTM** |
|
||||
| 0005 | nsterm.m, NEWS | **LGTM** |
|
||||
| 0006 | macos.texi, nsterm.m | **LGTM with nits** -- fix Known Limitations bullet; clarify @xref note |
|
||||
| 0007 | nsterm.h, nsterm.m | **Needs work** -- fix commit message (remove spurious ns_ax_face_is_selected entry); consider refactoring goto |
|
||||
| 0008 | nsterm.h, nsterm.m, macos.texi, NEWS | **LGTM with nits** -- remove spurious blank line in method body |
|
||||
|
||||
**Bottom line**: Two patches need targeted fixes before submission (0002:
|
||||
remove unrelated string change; 0007: correct commit message). After
|
||||
those fixes, the series is ready for emacs-devel.
