- README quick-start gains a multi-pass example using the new
Disc::copy + Disc::patch primitives.
- New docs/rip-recovery.md documents the two-stage rip model: mapfile
format (ddrescue-compatible), CopyOptions/PatchOptions surface, the
pass-1/pass-2 algorithm, and the design decisions (why no MODE
SELECT, why ISO intermediate, why ddrescue mapfile).
No code change.
autorip 0.11.22 ships the full multi-pass UI (live mapfile stats,
bad-range viz, Recovery settings). libfreemkv API is unchanged from
0.11.21. Part of the 0.11.22 ecosystem sync.
New primitives for two-stage rip workflows: fast forward pass with
zero-fill on failures, then targeted retries of bad ranges via a
ddrescue-compatible mapfile.
- Disc::copy now takes &CopyOptions (breaking change from positional
args). Always writes a sidecar .mapfile. Opt-in skip_on_error +
skip_forward give ddrescue-style fast sweep: 64 KB blocks,
exponential skip-forward on failure, zero-fill bad blocks. Defaults
preserve pre-0.11.21 behavior (recovery reads, abort on bad sector).
- Disc::patch is new and idempotent. Reads the mapfile, re-reads every
non-finished range with full drive recovery, patches good bytes back
into the ISO at exact offsets. Call N times for N retry attempts.
- disc::mapfile is a new module. ddrescue text format, crash-safe
(flushed on every record()), greppable, human-editable, tool-compatible.
Status chars match ddrescue: ? / * / / / - / +.
- Re-exports FileSectorReader from the crate root.
- freemkv CLI caller (pipe.rs) updated to the new Disc::copy signature
in lockstep — shipped in the 0.11.21 freemkv CLI release.
Part of the 0.11.21 ecosystem sync (libfreemkv + freemkv + bdemu +
autorip all on 0.11.21).
DiscStream::fill_extents loops internally while the demuxer waits for
enough clean data to emit a PES frame. In a dense bad zone that loop
can run for minutes without returning to the outer read() call, so
the caller's Stop signal never gets serviced until a frame is finally
emitted — which may be very far away.
Add DiscStream::set_halt(Arc<AtomicBool>) — typically wired to
Drive::halt_flag() for unified Stop across drive recovery phases and
stream sector processing. fill_extents checks the flag at the top of
every retry iteration; raising it returns Err(Error::Halted) within
one SCSI round-trip.
No behavior change for callers that don't call set_halt. Unblocks the
architectural fix for the "Stop doesn't stop" bug observed on a
damaged UHD disc.
Replace read_with_binary_search + 3×5s light recovery with an adaptive
sizer that shrinks on failure (halve, 3-aligned ≥6) and probes back up
after 100 MiB (51,200 sectors) of clean reads. Descent cost is paid
once per bad region, not once per bad sector.
Emit BatchSizeChanged { new_size, reason } on shrink and probe-up.
Remove BinarySearch event — no longer produced.
Side fix: scsi/macos.rs one-liner for manual_c_str_literals clippy
lint that surfaced on a newer toolchain.
