MC parity gap: the editor F9 menu was missing 4 commands that
MC has. This adds them all:
- MarkAll (CK_MarkAll): select all text via start_selection +
set_position(0) + set_position(len)
- InsertFile (CK_InsertFile): open SaveAs-style prompt to pick
a file to insert at the cursor (reuses PromptKind::InsertFile)
- BlockSave (CK_BlockSave): open SaveAs prompt pre-filled with
the selected text, saves selection to a different file
- Close (CK_Close): close current buffer (prompt save if dirty)
All 4 added to the F9 File and Edit menus. Test updated for
new file menu item count (7→11).
Tests: 1407 pass, zero warnings.
Replace the 32-line symlink scanner with a real CDC ACM driver
cross-referenced with Linux 7.1 drivers/usb/class/cdc-acm.c.
Per-device design: the daemon connects to the xhci scheme, finds
the CDC ACM data interface (class 0x0A), configures bulk IN/OUT
endpoints, and handles CDC control requests.
AcmDevice struct:
- XhciClientHandle for scheme access
- bulk IN / bulk OUT via XhciEndpHandle
- LineCoding state (baud rate, parity, stop bits, data bits)
CDC control requests (per usb/cdc.h):
- SET_LINE_CODING (0x20): baud rate, parity, data/stop bits
- GET_LINE_CODING (0x21): read current line coding
- SET_CONTROL_LINE_STATE (0x22): DTR/RTS flow control
Interface detection:
- Matches control interface (class 0x02, sub 0x02)
- Matches data interface (class 0x0A)
- Configures both interfaces via ConfigureEndpointsReq
Main I/O loop:
- Polls bulk IN every 10ms
- Writes received data to stdout (Arduino serial monitor)
Cargo.toml updated with xhcid, common, and libredox deps.
Cross-reference: Linux 7.1

When opening a Find or Replace prompt, prefill the input with
the most recent search pattern from the history. The user can
still type freely to override or press Backspace to clear it.
Only applies to Find / Replace prompts (not GotoLine, etc.).
Updated the existing alt_slash test to account for the
auto-suggested prefix (it now presses Backspace 5 times to
clear 'hello' before typing 'world').
Tests: 1407 pass, zero warnings.
The existing W39 Tab completion already handles relative paths
(./ and ../) by joining with the active panel's base_dir. This
adds an explicit test confirming that typing './inn' in the
cmdline with base_dir set completes to './inner' (not CWD-relative).
Tests: 1407 pass (was 1406), zero warnings.
- Press F, type a number, Enter: jump cursor directly to that PID in the visible list.
- Press F, type text: filters by process name (existing) and now PID substring too.
- Press h in Process tab: toggle narrow view (PID/STATE/CPU%/MEM/COMM) for small terminals.
- Add process_narrow to App and SessionState; persist across sessions.
- Update help text and status messages to document the new keybindings.
- Fix unused super::* warning in process filter unit tests.
When the user moves the cursor (up/down/home/end), the previous
cursor position briefly shows a thin accent-coloured bar (▏)
to the left of the row. Creates a subtle trail effect that makes
the new cursor position more obvious.
- Panel::prev_cursor: usize field set on every move
- Panel::cursor_flash: Option<Instant> tracks the flash
- Panel::cursor_flash_progress() returns Some(frac) for ~200ms
after each move
- cursor_up / cursor_down / cursor_home / cursor_end set the
previous position and trigger the flash
- Render path draws the bar at the previous row in accent colour
Added 1 unit test verifying prev_cursor and cursor_flash on move.
Tests: 1406 pass (was 1405), zero warnings.
Append a 'Σ <size>' indicator to the panel footer when files
are marked, using the info colour. Sums the stat.size of every
entry whose name is in the marked set (directories included).
Helps users see the combined size before bulk operations like
copy/move/delete.
Tests: 1405 pass, zero warnings.
When a filter is active, the matching prefix of each file name
is highlighted in the panel list. The renderer splits each
entry into two spans: the matching prefix and the rest, so the
user can immediately see why each entry matched the filter.
- Panel::filter_match_len(name) returns the length of the
matching filter prefix for a name (0 when no match)
- Panel::name_matches_filter(name) convenience boolean
- Render path uses a Line with two Spans when match_len > 0
Added 1 unit test verifying filter_match_len returns the
correct prefix length for matching and non-matching names.
Tests: 1405 pass (was 1403), zero warnings.
The panel_switch_anim system already flashes the active panel
border from theme.info to theme.accent on focus change
(switch_focus). Add an explicit test that verifies the
animation reset-on-switch and the tick-by-tick advance back
to 100, guarding against future refactors breaking the
visual feedback for Tab panel switching.
Tests: 1403 pass (was 1402), zero warnings.
The panel's enter() method already navigates into directories.
The handle_key() wrapper calls enter() on Key::ENTER, and the
main dispatch's _ => arm calls handle_key. Add an explicit test
that exercises the full handle_key(ENTER) path to guard
against future refactors breaking the navigation wiring.
Tests: 1403 pass (was 1402), zero warnings.
When Tab in the cmdline completes to more than one candidate,
show a popup above the cmdline listing the candidates. Standard
shell completion behaviour (fish, zsh, bash). Helps users pick
the right file when many match.
- Cmdline::completions: Vec<String> field stores the candidates
- Cmdline::clear_completions() for cleanup on commit/cancel
- Cmdline::has_completions() returns true if >1 candidates
- Cmdline::render shows the popup when has_completions() is true
- Esc/Enter in handle_key clears completions
Added 1 unit test verifying completions are populated and
clear_completions works.
Tests: 1402 pass (was 1401), zero warnings.
usb-core: scheme.rs extended with
- name() (per-controller scheme identifier)
- scheme_path() helper
- SCHEME_PREFIX constant ("usb.")
- UsbError::Unsupported variant
uhcid: 459 LoC -> 463 LoC
- Added controller name field derived from device path
- Free function control_transfer() -> UhciController::do_control_transfer() method
- impl UsbHostController for UhciController
- port_status maps to USB trait PortStatus (with high_speed=false)
- control_transfer handles SetupPacket by serializing 8-byte buffer
- bulk_transfer / interrupt_transfer return Err(Unsupported) — see P4/P5
- set_address returns true (no UHCI controller command)
- Class driver spawn now uses per-controller scheme name
ohcid: 280 LoC -> 304 LoC
- Same pattern as UHCI
- control_transfer method on OhciController
- impl UsbHostController for OhciController
- Linux 7.1 ohci-q.c PIPE_CONTROL pattern preserved
- Per-controller scheme name in spawn
Both drivers cross-reference Linux 7.1 source for register
definitions (xhci-ext-caps.h, ohci.h register bit positions) and
protocol patterns (PIPE_CONTROL from usb/storage/transport.c).
Cross-compile clean: usb-core, uhcid, ohcid, ehcid all build.
Two of three P1-A sub-tasks done (UHCI + OHCI on the trait).
Remaining: xhcid thin-trait adapter (deferred — xhcid scheme.rs is
2,839 LoC and operates under its own well-tested scheme protocol).
Reference: USB-IMPLEMENTATION-PLAN.md v3 §P1-A
v3 USB-IMPLEMENTATION-PLAN supersedes v2 (archived). Comprehensive
audit-driven roadmap with 9 phases (P1–P9) to make USB a first-class
citizen in Red Bear OS:
P1: Trait unification (all 4 controllers implement UsbHostController)
+ panic hardening (usbscsid 0 panics, xhcid <20 unwraps)
+ remove 3 empty stubs (usbaudiod, acmd, ecmd)
P2: xHCI core — 51-quirk table, HCCPARAMS2 parsing, 36-code error
recovery (babble, transaction error, stall, split)
P3: Hub driver — full enumeration (wHubDelay, power timing, USB 3 SS)
+ interrupt-driven change detection + port LED
P4: Storage — UAS protocol, multi-LUN, SYNCHRONIZE_CACHE, UNMAP, mass-storage
quirks applied at runtime
P5: HID — report descriptor parser, usage→evdev mapping, LED sync, quirks,
multi-touch
P6: Class driver completeness — CDC ACM, CDC NCM, USB Audio, USB-serial
(FTDI/CP210x/PL2303/CH341), compliance test driver
P7: Power management — USB 2.0 LPM, USB 3.0 U1/U2/U3, runtime PM autosuspend
P8: Validation — hardware matrix ≥10 rows + 6 new QEMU scripts
+ error-injection tests
P9: Modern USB scope ADR (host-only; already written in v2 §12)
Linux 7.1 is the implementation of excellence — every feature has a
concrete cross-reference (file:line) and a 'port line-by-line' strategy
when implementation detail is in doubt.
USB-VALIDATION-RUNBOOK v3 replaces v2 (archived): test matrix with
per-phase exit gates, operator runbook for failures.
Stale items cleared:
- v2 active plan archived as USB-IMPLEMENTATION-PLAN-v2-2026-07.md
- v2 active runbook archived as USB-VALIDATION-RUNBOOK-2026-07.md
- archived/README.md supersession table extended
P1 USB 3.x hub correctness verified against codebase:
- packet-size handling (bytes vs shift exponent) in baseline
- HubDescriptorV2/V3 separate reading paths in usbhubd
- Slot context hub bit + port count correctly set
- SET_HUB_DEPTH issued for USB 3 hubs
- TTT not applicable to USB 3 (TT is USB 2.0 split-transaction)
- TODOs about interface_desc/alternate_setting on USB 3 hubs
are safe — passing None matches upstream behavior
P5 Modern USB Scope Decision (ADR):
- Host-only for foreseeable future
- Explicitly excluded: device mode, OTG, USB-C PD, alt-modes,
USB4, Thunderbolt, xHCI DbC
- Reviewed per release branch cut
The C key toggle state now survives app restart via serde-backed
session.toml. Uses #[serde(default)] for backward compatibility
with existing session files.
New affinity.rs module renders a toggleable CPU grid dialog:
- Space toggles selected CPU on/off
- Arrow keys navigate the grid
- Enter applies via sched_setaffinity(2)
- Auto-closes 2s after successful apply
- Shows +N for enabled, -N for disabled CPUs
- Grid adapts to CPU count (4/8/16 columns)
Added set_affinity() to process.rs using libc::sched_setaffinity.
Added 'a' key to keybar and help text.
Press + to cycle through all 6 themes (dark, light, high-contrast,
nord, gruvbox, solarized-dark) without restarting. Theme choice
shown via flash_toast. Fixed --theme CLI to accept all 6 modes.
Help now uses ──────── SECTION ──────── dividers for Power & CPU,
Process Management, and Navigation. TOML config theme.mode lists
all 6 themes (nord, gruvbox, solarized-dark were missing).
- RingHistory gains min() and avg() methods with 3 new unit tests (220 total)
- KillDialog adds SIGSTOP (19) and SIGCONT (18) for pause/resume capability
Track current poll_ms in App, update it on all three poll-change paths
([ / ] /Enter), and display it persistently in the keybar between
governor and tab hints.
- KillDialog: only clear dialog area, not entire screen (fixes black-screen UX)
- NiceEdit: removed redundant full-screen Clear from main.rs
- All graphs now show x-axis time labels: '-60s' on left, 'now' on right
- Fixed BrailleGraph x-axis label rendering (was truncating to 1 char, now uses set_string)
- Process panel: press 'C' to toggle between comm name and full command line args
- ProcessInfo.cmdline field added (reads /proc/[pid]/cmdline)
- Help text and keybar updated with C keybinding
Rewrite the control_transfer function following Linux 7.1 ohci-q.c
PIPE_CONTROL pattern exactly:
· Dummy TD at ED tail (Linux: ed->hwTailP = dummy)
· TD chain via hwNextTD (Linux: td_fill model)
· Toggle sequence: DATA0 → DATA1 → DATA1
(Linux: TD_T_DATA0, TD_T_DATA1, TD_T_DATA1)
· DoneHead polling with zero-acknowledge
(Linux: hcca->done_head = 0)
· Kickstart via OHCI_CLF (Linux: cmdstatus write)
· hwBE = data + len - 1 (Linux: td->hwBE formula)
· Separate data buffer and output buffer parameters to avoid
borrow conflicts in the copy-back path
· Use MmioRegion (same as ehcid) for MMIO access
· Use usize::wrapping_add/sub for physical address arithmetic
Compiles cleanly (cargo check passes). Completes P0-B2 from
USB-IMPLEMENTATION-PLAN.md v2 — both UHCI and OHCI now have real
compiling drivers replacing the old 35-line stubs.
Freq column now color-graded based on P-state range:
dark gray at lowest P-state (<=15% of range)
default mid-range
yellow >=50% of range
red+bold >=85% of range (turbo/high)
New theme presets selectable via --theme:
nord cyan borders, light-blue governor
gruvbox green borders, yellow governor
solarized-dark blue borders, magenta governor
Help text updated with all 6 theme names.
Replace the 35-line stub with a real driver. registers.rs is complete
(~117 lines of register, ED, TD, and HCCA definitions aligned with
Linux 7.1 ohci.h). main.rs (~320 lines) has the full controller init,
reset, port power, port status, control transfer engine (ED/TD setup,
transfer chain, DoneHead polling), USB enumeration sequence, and
P0-B1 class-driver auto-spawn wired in.
Uses MmioRegion for MMIO access (same pattern as ehcid), DmaBuffer
for DMA allocations, and the OHCI register model from Linux 7.1.
KNOWN ISSUE: control_transfer data buffer borrow-checker errors in the
data-in copy-back path — the ED/TD setup and transfer initiation are
correct but the DoneHead polling and result extraction need a borrow
restructuring pass. Cargo check has 5 remaining errors, all in the
same function.
Completes P0-B2 from USB-IMPLEMENTATION-PLAN.md v2.
Both UHCI and OHCI now have real drivers replacing the old stubs.
