macOS E2E QA: platform parity fixes, -l builtin host, 'number' gutter, lint cleanup - #38
Conversation
…lint cleanup - ox-sys unix/macos queries replace /proc-dependent runtime code (getpwuid_r, proc_pidinfo, proc_listchildpids, kill(pid,0)) - pty slave path via portable-pty tty_name() (ttyname(master) is NULL on macOS) - getcwd-aware test expectations for /var,/tmp -> /private/... canonicalization - APFS non-UTF8 filename tests gated off macOS (EILSEQ, platform cannot hold them) - nvim -l binds the editor-backed builtin host (EditorBuiltins) so stateful builtins like mkdir() reach the editor; print() flushes messages to stdout - TUI renders 'number'/'relativenumber' gutter (numberwidth, LineNr groups) - guifont startup metadata reports the per-OS DFLT_GFN via option metadata - fix /bin/true -> /usr/bin/true probes; deterministic stdin pipe capacity probe - drop testnvim group from just functional (helper dir, no *_spec.lua) - clippy: allow unwrap/expect in test modules, remove dead helpers - re-bless differential SKIPS fingerprints for this oracle/host

Size a relative-only gutter from the window height.
With nonumber relativenumber, this expression still sizes the gutter from the entire buffer. Neovim uses the window’s row count for this configuration. For a million-line buffer in a 24-row window, this code reserves eight columns instead of the default four. That needlessly reduces text width and changes wrapping. Use line_count when number_on is true and the window height otherwise. (neovim.io)

Clamp the gutter before the content write.
For a three-column number-only window with numberwidth=4, gutter is four. Line 559 passes that value to Grid::write_text, which returns GridError::OutOfBounds instead of clipping the write. The error propagates through the redraw.
Clamp gutter to geometry.width.saturating_sub(1) before deriving text_width. The cursor tuple can exceed the layer width, but composition already discards out-of-range cursor coordinates.
Suggested fix
- let gutter = sign_width.saturating_add(number_width);
+ let gutter = sign_width
+ .saturating_add(number_width)
+ .min(geometry.width.saturating_sub(1));📝 Committable suggestion

🔍 Additional research query:
GitHub Grep: inspect the official libuv repository implementation of uv_getrusage, specifically src/unix/getrusage.c or equivalent, and determine how ru_maxrss is normalized on macOS/Apple platforms.
💡 Result:
## Github Grep
- In the official `libuv/libuv` repository, `uv_getrusage()` delegates to `uv__getrusage()` in `src/unix/core.c` (the equivalent implementation to `src/unix/getrusage.c`). (Source: Github Grep · searchGitHub)
- Under `__APPLE__`, libuv normalizes `ru_maxrss` by dividing it by `1024`; the comment states macOS and iOS report the value in bytes, while most platforms report kilobytes. (Source: Github Grep · searchGitHub)
Normalize Darwin ru_maxrss before exposing Rusage.maxrss.
Darwin reports ru_maxrss in bytes. libuv divides this value by 1024 on Apple platforms. The current mapping exposes bytes through a field documented as kilobytes, so macOS callers receive a value 1024 times too large. This is a localized metric error, not a workflow-blocking failure.
Suggested fix
- maxrss: field(usage.ru_maxrss),
+ maxrss: field(usage.ru_maxrss / 1024),-/// `uv_getrusage` (field units stay platform-native: `ru_maxrss` is bytes on
-/// macOS, kilobytes on Linux, exactly as libuv passes it through).
+/// `getrusage` returns platform-native units: `ru_maxrss` is bytes on macOS
+/// and kilobytes on Linux. The `ox-uv` layer normalizes macOS `maxrss` to
+/// kilobytes, matching libuv.📝 Committable suggestion

Share executor state for run_lua re-entry.
EditorBuiltins::dispatch uses nested_ex when ex is already borrowed. The two executors in run_lua do not share user commands, user functions, the quit bus, or session lifecycle state. A command or function defined through primary can therefore be unavailable to the fallback executor. Quit and exit state can also diverge.
Share the same state as build_embedded_core:
Suggested fix
let mut nested = ExExecutor::new();
+ nested.share_quit_bus_from(&primary);
+ nested.share_user_commands_from(&primary);
+ nested.share_user_functions_from(&primary);
+ nested.share_session_from(&primary);

The default just functional path now omits the entire upstream test/functional/testnvim directory, although the targeted-filter path can still run it. Consequently, the acceptance command can report success without exercising that group's API and execution tests, masking compatibility regressions against the executable specification.

Kept removed deliberately: in the pinned reference (d5e7c7e), test/functional/testnvim/ contains only exec_lua.lua — a helper, zero *_spec.lua files — so the group fails RunTests with 'No test files found' and runs zero tests either way. find .references/neovim/test/functional/testnvim -type f → exec_lua.lua only. Nothing is masked; if upstream adds specs there later the group can come back.

When 'number' or 'relativenumber' is enabled and the buffer is shorter than the window, this new gutter reduces text_width, but the filler-row branch still writes ~ at column 0 and highlights only [1, text_width). The marker therefore overwrites the sign/number area instead of appearing after it, while the right side of the row is left with the wrong highlight; the filler branch needs to apply the same gutter offset as ordinary lines.

Checked against the oracle (nvim --headless + screenstring): with number on, upstream still draws ~ at column 0 over the gutter region, so the put offset is correct. What was wrong is the NonText span — it stopped at text_width; now spans the full geometry.width row like upstream.

If an nvim -l script calls print() or nvim_out_write() and later raises an uncaught Lua error, this ? returns before the newly added message-stream flush runs, so all output produced before the error is lost. Those writes are externally observable before the failure in Neovim; retain the execution result, flush queued messages on both success and failure, and then propagate the error.

On macOS, getrusage(2) reports ru_maxrss in bytes, while libuv normalizes that field to kilobytes before exposing uv_getrusage. Copying the native value directly makes vim.uv.getrusage().maxrss 1024 times larger than Neovim's value on every macOS process, which can break plugins using it for memory telemetry or limits.

On Linux systems or containers where procfs is mounted but the optional /dev/fd symlink is absent, every vim.uv.new_tty(fd, ...) call now fails with ENOENT; the previous /proc/self/fd/{fd} path works in that environment. Use target-specific paths—/proc/self/fd on Linux and /dev/fd on macOS—rather than replacing the Linux backend globally.

When a window with 'number' or 'relativenumber' is resized to four columns or fewer, the minimum number gutter consumes or exceeds the whole grid, but this call still starts writing buffer text at gutter. Grid::write_text explicitly returns OutOfBounds when its start column is at or beyond the grid width, so a valid narrow split causes the entire compositor refresh to fail instead of rendering a clipped window.

Fixed in e48c80a — gutter clamps to width-1 (same fix as the CodeRabbit narrow-window thread).
- split_window copies window-local options like upstream copy_winopt, skipping scroll/previewwindow/winfixbuf/winfixheight/winfixwidth - rnu-only gutter sizes from window rows, not buffer line count - cursorlineopt "both" selects CursorLineNr (it is the default value) - clamp gutter below grid width so narrow windows can't hit OutOfBounds - EOB ~ rows span NonText across the full window width - getrusage maxrss normalized to kilobytes on macOS (libuv semantics) - run_lua nested executor shares user commands/functions/quit/session - run_lua flushes printed output on the Lua-error path too - new_tty keeps /proc/self/fd on Linux, /dev/fd on macOS

Devin Review caught that a window narrower than sign + number fields drew the right-aligned digits into cells the clamped gutter no longer owned, then buffer text overwrote them. Match win_col_off instead: the gutter keeps its natural width, text only draws when a text column exists, and every draw call guards on its start column. A window narrower than the gutter now shows the clipped gutter cells only, exactly like upstream.

🔍 Lua script host bypasses shared wiring
run_lua installs editor-backed builtins but skips the command, Lua, autocmd, and job hosts in build_embedded_core. The documented -l limitations therefore persist; review whether this partial host is the intended supported surface.
Was this helpful? React with 👍 or 👎 to provide feedback.
There was a problem hiding this comment.
Confirmed — this is the intended surface for this PR, not an accidental omission. run_lua shares the executor tier (user commands, user functions, quit bus, session state) so vim.fn/print work like the embed path, but it deliberately does not construct build_embedded_core's full runtime: there's no event loop under -l, so set_lua_exec/set_autocmd_executor/the job-callback delivery pass would have nothing to pump them. Upstream -l runs a real event loop — wiring one in (plus fork_seed, LuaScheduler, and deferred job-event delivery) is a proper follow-up feature, out of scope for a macOS parity PR. The limitations are documented in the PR body ("under -l, vim.cmd has no Ex host; Lua job callbacks have no delivery pass"). Flagging for a human call as marked.
Three adversarial-probe findings against the oracle: - `:vertical resize` ignored the modifier and always resized height; it now takes the width path (relative to w_width, bare arg = Columns). - Unparseable args including bare "+"/"-" contribute 0 per atol semantics, so `resize +` is a no-op instead of +1. - A window address past the last window clamps to it instead of erroring (ex_docmd.c:5950). - set_window_extent clamps an out-of-range request to the extent the neighbors allow instead of E36 (window.c frame_setheight/setwidth); E36 remains only when even minimum extents cannot fit. Remaining known gap: `:resize`/`:vert resize` on a window with no same-axis split ancestor (e.g. pure-vsplit for height) still errors — upstream shrinks the band and leaves dead space, which the frame model cannot express yet.

In a fresh session the render HlState is empty, so enabling 'number' causes these calls to synthesize the groups, but the fallbacks differ from the canonical defaults already initialized on Editor: LineNrAbove/LineNrBelow link to LineNr, while CursorLineNr is bold. Here relative rows instead receive independent teal groups and the cursor row an olive, non-bold group, so default rendering drifts and colorschemes that customize only LineNr no longer affect relative numbers. Seed or resolve the canonical group definitions rather than hardcoding separate RGB fallbacks.

When a placed sign supplies numhl (including a sign with no text), its number_highlight_group is stored on the extmark, but this selection only considers the standard LineNr* groups and the compositor never consults that attribute. Consequently :set number followed by a sign such as :sign define X text=! numhl=ErrorMsg renders the sign glyph but leaves the associated line number unhighlighted, unlike Neovim; choose the winning sign's number highlight before falling back to these standard IDs.

On Apple Silicon, machdep.cpu.brand_string is absent, and the adjacent comment explicitly notes that libuv leaves the model empty there; nevertheless this fallback substitutes the hardware identifier from hw.model. As a result vim.uv.cpu_info()[1].model returns values such as a Mac model code where Neovim's libuv-backed API returns an empty string, so plugins observe a platform-specific compatibility drift. Do not substitute hw.model when the libuv source value is unavailable.

When a window has 'number' and 'signcolumn=number', signcolumn_bounds returns (0, 0), so this clamps sign_slots and sign_width to zero; the later sign binning and drawing paths are both gated on nonzero sign_width. As a result, placed sign glyphs disappear instead of replacing the line number in the number column. Render the selected sign through the number-column path rather than treating zero dedicated columns as no signs.

When :vertical wincmd = or :horizontal wincmd = is used, Neovim equalizes only heights or only widths respectively, but this branch always calls equalize_tabpage and changes both dimensions.

Window extent changes (set_window_width/height, equalize_tabpage) now
revalidate every tiled window's topline so a shrunken frame scrolls its
cursor back into view instead of emitting grid_cursor_goto positions
outside the resized grid (upstream win_new_height/validate_cursor). The
extracted helper reuses the resize_tabpage fix-up.
:wincmd {count}{char} now reads the post-command count the COUNT-flagged
parser already extracts (wincmd 10< resizes by 10, matching the oracle)
in addition to the pre-command :10wincmd range; both land in
eap->line2 for do_window (ex_docmd.c:6583).

crossterm's kitty keyboard path reports the unshifted keycode plus SHIFT (`,` + Shift for `<`, `.` + Shift for `>`), while raw-byte terminals report the shifted glyph itself. The encoder forwarded the base keycode verbatim, so `C-w <`/`C-w >` chords arrived as `,`/`.` motions (find-back / repeat-edit) and every shifted-punctuation chord on a kitty-protocol terminal was dead. Translate base keycode + SHIFT through a US-layout table in `encode_key` so both terminal kinds emit the same glyph. AI-assisted
The compositor derives the cursor row from the wrapped-line count of `topline..lnum`. Narrowing a pane (`:vertical resize -30`, `wincmd =`) inflates wrapped rows past the text area, emitting a cursor row the receiving grid rejects as `GridPositionOutOfBounds` — a deterministic TUI crash with a scrolled cursor in multi-pane layouts. Clamp the row to `text_height - 1`, matching the bottom-row position upstream leaves the cursor at after its scroll pass. AI-assisted

When 'number' or 'relativenumber' leaves only a very narrow text area and the cursor is late on a long wrapped line, forcing text_width to at least 1 makes the cursor-row calculation treat clipped text as one-cell segments, potentially producing a row beyond text_height. The multigrid emitter then sends that invalid row unchanged in grid_cursor_goto, while the single-grid compositor drops the cursor and leaves it stale. Scroll or clamp the wrapped cursor segment into the visible grid instead of modeling a fully consumed gutter as a visible one-cell text area.

In nvim -l, editor messages are now flushed only after the entire chunk finishes, while Lua io.stdout/io.stderr writes happen immediately. A script such as print('first'); io.stderr:write('second\n') therefore emits second before first, unlike Neovim's synchronous message write path. Flush completed message lines during execution, or otherwise coordinate them with direct stream writes, so externally observable output order is preserved.

There was a problem hiding this comment.
When four or more signs overlap one row under a setting such as 'signcolumn=auto:9', the live sign depth has already been capped to three before these new option bounds are applied. The computed width therefore remains three slots and the later .take(sign_slots) omits every additional sign, even though the option explicitly permits up to nine columns. Preserve the actual overlap depth here and clamp it only to the parsed max_sc.

`wincmd_command_end` read the first argument byte as the window key, so
`wincmd 10< | cmd` took `1` for the key, missed the `|` boundary, and
delivered "10< | cmd" as one argument — E474 where upstream runs the
tail. Skip the leading count digits (and spaces) before reading the
key so `check_nextcmd` sees the same boundary as the bare-key form.
Also adds the typeahead-path regression test for `C-w <`: two key
strings appended the way `nvim_input("<C-w>")` + `nvim_input("<")`
produces them must dispatch to `wincmd`, not the `<` operator.

When an nvim -l script passes an unsupported status such as os.exit({}), the stock LuaJIT function raises a bad-argument error, allowing code such as pcall(os.exit, {}) to continue. This replacement maps every unrecognized value to status 0 and immediately terminates the editor successfully instead, changing both control flow and the externally visible error. Decode the argument with LuaJIT-compatible coercion and return an argument error for invalid values.

Conflicts resolved by keeping both sides' behavior: - job.rs: non-unix spawn keeps upstream-style pump teardown, extended to the pty_slave tuple the unix arm already carried. - compositor.rs: skiprows (w_skipcol) segment skip composes with the 'number'/'signcolumn' gutter and the grid_cursor_goto row clamp. - builtins.rs hostname: /proc -> HOSTNAME -> gethostname() chain now serves unix (ox_sys::unix::hostname) and windows arms alike. - misc.rs uptime: macos + windows arms with a shared fallback. - uv_core.rs stdin_pipe_capacity: O_NONBLOCK probe kept under cfg(unix).

…eam semantics
The Vimscript string lexer emitted internal three-byte keycodes for
\<name> escapes whose byte sequences are invalid UTF-8, producing
U+FFFD mojibake in buffers (e.g. feedkeys("i\<Esc>") typed stray
characters). Rewrite the escape path as a faithful port of
find_special_key + special_to_buf: dash/modifier scanning with the
t_/char-/\""> lookahead rules, the full keycode_names table, the
75-row simplify table, extract_modifiers folding, vim_str2nr
(0x/0o/0b/binary, bare-0 decimal, E474 on malformed char- numbers),
literal-< fallback on every non-match, and the NUL-keycode rejection.
All 186 key names and ~40 modifier/edge probes are now byte-identical
with the reference nvim.
keytrans() now prefers the canonical key names upstream reports for
control bytes (Tab, NL, C-\, C-], C-^, C-_) and passes raw bytes 0 and
127 through instead of inventing <C-I>/<Del>.
Insert mode gains the missing Ctrl chords, oracle-verified: CTRL-W
(word-class delete incl. trailing whitespace), CTRL-U (delete to the
insert-session anchor, with the col-0 join that undoes a bare o),
CTRL-V/CTRL-Q literal insertion with decimal and x/o/u/U charcode
runs (non-digit terminator is pushed back upstream-style), CTRL-R
register insertion (characterwise splice, linewise replace-line), CTRL-C
exit, and CTRL-E/CTRL-Y sibling-line characters. Remaining unported
insert chords: CTRL-K digraphs, CTRL-A/CTRL-@ last-insert, CTRL-X
submode selectors, and the = expression register.

Normal mode had no handlers for the compound editing keys: Y, D, C, X, s, and S were all dead. They are now their upstream equivalents — y$/d$/c$ over the cursor-to-EOL span, dh for X, cl for s, and linewise cc for S — with c$/cc entering Insert via the operator result and C on an empty line still opening Insert like upstream. j/k motions now fail when the full count cannot be met instead of clamping: upstream cursor_up/cursor_down return false and nv_updown aborts with clearopbeep, so 3j on the last line discards the rest of the stuffed input rather than running it at the buffer edge. feedkeys() flags now reflect f_feedkeys' ins_typebuf nottyped=(!t): strings stuffed without 't' count into tb_maplen, so an operator error's beep_flush discards their tail and q recordings skip them; strings stuffed with 't' are typed keys — recorded, synced per key for undo blocks, and never error-flushed. j/k-at-boundary, stuffed feedkeys, and recording probes are all byte-identical to the reference nvim. AI-assisted
Resolve the ox-tui clean-exit race twice-fixed on both sides: keep upstream's successful_exit (waits for the child to quit before declaring the send failure clean) and the finish_run helper it feeds, dropping this branch's exited_successfully shim. AI-assisted
readfile's EOL detection (fileio.c) now runs on every buffer file load — :edit reloads, buffer switches, :tag file opens, and startup argument files — so a CRLF file reads as 'fileformat'=dos with the CRs dropped and a file without a trailing newline sets 'endofline' off, instead of everything reading as unix with literal CRs left in lines. The guess follows upstream's decision tree: 'binary' and an empty 'fileformats' keep the buffer's own format; the first NL picks dos when 'dos' is tried and the NL is CR-preceded (or 'unix' is not tried), otherwise unix; a unix verdict on a file holding CRs before that NL is re-scored against mac on raw CR-vs-NL counts; CRs with no NL at all mean mac when tried; a marker-free file takes the first 'fileformats' entry; and a bare NL inside a dos read rewinds the file as unix when 'unix' is also tried. Writes now serialize through 'fileformat' (dos joins with CRLF, mac with CR) and end the file when 'endofline' is set or 'fixeol' fixes it, but never under 'binary' without 'endofline' — previously every write appended a plain newline. &no<opt> reads resolve a boolean option negated, matching upstream's option lookup prefix handling. Verified byte-identical against the reference nvim on unix, dos, mac, no-eol, CR-only, and mixed-separator files, plus write round-trips under dos, fixeol, and nofixeol. AI-assisted
The reference nvim rejects '&noeol'/'&noendofline' with E113 like any other unknown option name, so negating them would drift from upstream rather than match it. AI-assisted
