scripts: rebuild the dev loop around build.sh/run.sh

2026-11-01T14:53:29Z

`make` did not parse at all (missing separator at line 139), so every make target was dead. The folder also carried three overlapping launchers (boot.sh, qemu.sh, boot-image.sh) plus a fourth partial one in the Makefile, `cargo build --package rsdos` copy-pasted eight times, the QEMU invocation copy-pasted per script, and the test helpers (fail/wait_log/wait_qemu_exit/qemu_hmp) duplicated in five tests. New layout: - scripts/lib.sh: single config (image, OVMF, mem/smp), the one cargo invocation (build_all), the one QEMU shape (qemu_args), and the test harness (test_boot, wait_log, wait_qemu_exit, qemu_hmp, sendkeys) - scripts/build.sh: kernel + every bins/* in one pass - scripts/mksystem.sh: freshness-aware image build that now stages every bins/*.efi into /bin/cli|gui (they were never copied before) - scripts/run.sh: build + stage + boot in one command; --headless, --debug (GDB stub), --monitor (HMP socket), --fresh, --mem/--smp/ --bios/--image; on Wayland it auto-selects XWayland plus grab-on-hover so the mouse can be captured (Ctrl+Alt+G toggles) - scripts/tests/: the five automated tests on the shared harness - deleted: boot.sh, qemu.sh, boot-image.sh, lib-boot-args.sh, build-image-release.sh, build-bootloader.sh (rsboot chain dropped) The Makefile is now a thin wrapper: make run, make test, make system, make inspect, make help. Two-command flow: ./scripts/build.sh then ./scripts/run.sh (run.sh alone also works). Stale test assumptions fixed so the suite is green again: test-gfx waited for "gfx: check" while the shell prints "gfx check: PASS"; test-mouse/test-msg hardcoded msgrecv = task 3 (wm-input took slot 3 — ids are parsed from the log now); the queue-full probe targeted task 0, whose exec pump drains its own queue as completion codes (moved to the cursor task, which never recvs). Verified in QEMU: make test -> test-disk, test-gfx, test-mouse, test-msg, test-fault all PASS.

build: default profile is release (debug too slow for dev loop)

2026-08-27T16:39:29Z

Makefile: PROFILE=release, CARGO_FLAGS=--release; make release target kept as no-op (now default). boot.sh: PROFILE=release default; --debug flag opt-in. mksystem.sh: PROFILE=release default. test-disk/fault/gfx/mouse/msg: all use --release. All scripts syntax-checked.

scripts: migrate all QEMU/test scripts to single system image

2026-08-27T16:35:59Z

boot.sh: replace esp/ + DISK_IMG with single SYSTEM_IMG on ide.0 (hooks into mksystem.sh --force for auto-staging). boot-image.sh: delegate to mksystem.sh --chain (build-image.sh deleted). build-image-release.sh: delegate to mksystem.sh --chain --gpt. qemu.sh: flexible launcher uses SYSTEM_IMG; --chain flag for full-chain build. test-disk.sh: drop ESP_DIR (mksystem.sh stages everything). test-fault.sh: boot system.img on ide.0 + CRASHLOG stick on ide.1; replace deleted mkdisk.sh with inline mkfs.fat. test-gfx.sh: system.img on ide.0, stage via mksystem.sh. test-mouse.sh: system.img on ide.0, stage via mksystem.sh. test-msg.sh: system.img on ide.0, stage via mksystem.sh. Makefile: remove stale build-image.sh/mkdisk.sh references from help; image target delegates to mksystem.sh --chain. All scripts syntax-checked (bash -n). build-image.sh and mkdisk.sh no longer referenced anywhere.

image: single dd-able system.img replaces vvfat+data-disk pair

2026-08-21T17:13:52Z

mksystem.sh stages one FAT32 image: \bzImage + \initramfs.cpio.gz (rsbl paths), \EFI\BOOT\BOOTX64.EFI (kernel direct by default, --chain for rsboot), \etc\motd.txt, empty \bin\cli + \bin\gui, seed files at the root. --gpt wraps it in a partition table for real USB dd targets. Makefile: run/run-gui/debug attach only system.img on ide.0 (vvfat lines deleted); stamp-based 'system' target rebuilds only when the kernel is newer, so runtime writes survive reboots; system-fresh wipes; inspect lists via mtools. build-image.sh/mkdisk.sh removed. test-disk.sh boots system.img with a throwaway OVMF varstore — a stale NvVars makes the firmware skip the \EFI\BOOT fallback. sendkeys.py pacing 50ms->250ms/1.5s: keystroke loss under host load corrupted typed lines (guest-side PS/2 ring overflow). Gate: test-disk PASS (fsck clean, file survives poweroff).

fix pi-lens warnings: unwraps, shell SC2046, dup code (fmtbuf/scripts/hexdump/cat/ahci/pci)

2026-08-01T16:25:55Z

- memory.rs: self-test Layout::from_size_align no longer panics — the test fails cleanly on an invalid layout - fat.rs: v() no longer unwraps the active-volume slot — invariant violation logs + halts instead of panicking mid-disk-io - strbuf: shared FmtBuf replaces the duplicated PanicBuf/FmtBuf (main.rs + sched.rs) - test-disk.sh: SC2046 — conditional --fresh arg no longer relies on word splitting - scripts: boot.sh/boot-image.sh share lib-boot-args.sh (dup args loop) - shell: cat/hexdump stdin pairs unified with Option<&str> marker; hexdump format_row folded into format_partial - ahci: read/write_sectors unified behind dma_sectors - pci: config_read/write share config_addr

shell: keyword redirection + post-filter flags (ADR 0002)

2026-08-01T11:14:07Z

Implement the shell experience redesign: one canonical grammar for every command — 'cmd args [USE src] [TIL marker] [filters...] [output kw dst]'. - Keyword redirection (uppercase-only, aliases valid, fully reserved): WRITING/WRITE overwrite, TO append, USE/USING input source, TIL/UNTIL heredoc/terminator (exact full-line marker). > >> < << are removed; '>' is plain text. - Post-filter stages applied left to right over a line stream, each repeatable: -h N (head kills the upstream), -t N (tail holds a rolling window, flushes at EOF/^C), -g PAT (smart-case literal substring), -p (screenful pager, terminal only). A file sink replaces the screen; -p is a no-op with one. - C-style quoting: "..." groups and literalizes, \x escapes one char; quoted/escaped text is never an operator, never split. - Input consumers: cat/hexdump, path-less only (stdin until ^D, USE f, TIL m heredoc, USE f TIL m truncation). Other commands reject input keywords; paths + input keyword is a syntax error. - ^D is EOF everywhere and never powers off; poweroff/exit are the only shutdown verbs. - help rewritten; test-disk.sh and sendkeys.py use the keyword syntax. Verified in QEMU: 26 grammar checks on fresh and reused disks, disk round trip, pager pacing, -h stopping /dev/mem at N lines, ^C flushing a -t window. Two bugs found during verification and fixed: 1. WRITING over an existing file wrote after stale NUL padding — fs::size() is stale after set_len(0); the sink writes at offset 0 after truncation. 2. USE f TIL m leaked the post-marker remainder — the final partial-line emit ran after the marker break; guarded with a stopped flag.

fat: mount every FAT32 volume under /disk//, fix multi-entry LFN

2026-08-01T00:19:07Z

- fat.rs: VOL: Option → VOLS: Vec; try_mount() returns a Volume per disk and init() mounts every valid FAT32 volume found. Volume UID = sanitized uppercase label + 8-hex volume serial (e.g. RSDOS-5BD1E55F): unique per format, stable across reboots, human-recognizable, machine-parseable (^[A-Z0-9_]+-[0-9A-F]{8}$); cloned volumes get a -N suffix. Public ops take a vol index and select it (select_vol also picks the backing AHCI disk), matching the ahci::select pattern - fs.rs: /disk is now a plain directory whose children are one Disk node per mounted volume, named by UID; DiskInfo carries vol - LFN fix: entries are stored last-first on disk — both the writer (head-entry first) and reader (append in disk order) were reversed and cancelled out for ≤13-char names; multi-entry names (>13 chars) read back mangled (e.g. 'from-kernel.txt' as 'xt'). Writer now places seq=1 closest to the SFN and seq=N|0x40 first; reader places chunks by sequence number and trims at the first NUL. Verified with a 25-char filename round trip: kernel ls/cat correct, mtools shows the full LFN, fsck clean on both volumes - test-disk.sh: test file renamed to disk-test-.txt (>13 chars, exercises multi-entry LFN); UID discovered from the boot log; QEMU stdio redirected to a log file + EXIT trap so an orphaned QEMU can never hang a piped caller (it previously did, 400s)

scripts: automate the data-disk workflow (mkdisk / sendkeys / test-disk)

2026-07-31T23:56:12Z

- scripts/mkdisk.sh: create the FAT32 disk with mkfs.fat -C (the flag that actually creates the file — plain mkfs.fat fails on a missing path), accept M/G/K sizes, seed seed/ files via mtools; --fresh re-formats, --no-seed skips seeding - scripts/sendkeys.py: type lines into the guest via the QEMU monitor (US layout). Punctuation must use QEMU's named keys (minus, slash, dot, ...) — bare '-', '.', '/' are not valid sendkey names, and '-' is the modifier separator, so they were silently dropped before - scripts/test-disk.sh: full automated round trip — build, deploy, ensure image, boot headless QEMU, drive the shell (ls /disk, mkdir, echo >, cat, poweroff), then verify with fsck.fat (must be clean) and mtype (file content must have survived poweroff) - Makefile: make disk / disk-fresh / inspect / test-disk; run, run-gui and debug now auto-create a missing DISK_IMG; fix the stale comment (mkfs.fat without -C) - scripts/boot.sh: auto-create a missing DISK_IMG via mkdisk.sh - seed/: motd.txt + lines.txt seeded onto fresh images - Verified end to end: ./scripts/test-disk.sh --fresh passes
