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.
Fix trailing sectors dropped at extent boundaries when sector_count % 3 != 0.
Add verify_title stop support via progress callback returning bool.
Add O_CLOEXEC on all SCSI fd opens to prevent leak to child processes.
Fix SCSI sense descriptor format detection (0x72/0x73 vs 0x70/0x71).
A stream is a stream. DiscStream::new() takes reader + title + keys +
batch + format — same pattern as every other stream constructor.
Deleted: open_drive(), open_iso(), from_reader() — these were helper
functions that chained multiple operations. Library provides primitives,
callers decide the sequence.
Removed disc:// case from input() — callers use Drive::open() +
Disc::scan() + DiscStream::new() directly for disc sources.
Architecture:
- One stream per format, bidirectional PES (read/write on same type)
- IsoStream merged into DiscStream (one type, any SectorReader)
- Disc::copy() for disc→ISO raw sector dump
- IOStream trait deleted, all byte-level Read/Write removed
- ContentReader/OpenDisc/open_title/open_input/open_output deleted
- CountingStream wrapper for progress tracking
Error codes:
- All io::Error English strings replaced with Error enum variants
- From<Error> for io::Error conversion
- Unused variants removed, new stream/mux variants added
Deleted: mkvout.rs, pesout.rs, isowriter.rs, mkv-muxer-plan.md
Updated: all docs, README stream table, CHANGELOG
238 tests, 0 clippy warnings.
Stream trait: read() returns PesFrame, write() accepts PesFrame.
A stream is a stream — you read from it or write to it.
No separate Input/Output traits.
API: libfreemkv::input(url) and libfreemkv::output(url, title, codecs)
Returns Box<dyn Stream>.
- SectorReader trait decouples disc scanning from SCSI
- Disc::scan_image() for ISO and any sector source
- resolve_encryption() handles AACS 1.0/2.0/none in one path
- IsoStream: full UDF/MPLS/CLPI/labels pipeline from ISO files
- StdioStream: stdin/stdout pipe
- Strict scheme:// URL format with validation
- Labels module refactored to SectorReader
- 7 stream types total
DriveProfile now has every field traced from firmware:
- drive_signature, unlock_init_value, unlock_response_size_minus_init
- ld_microcode (base64, ~1888B firmware payload)
- hardware_register_a_cdb, hardware_register_b_cdb (10B pre-built CDBs)
- drive_nominal_speed_cdb (12B calibration speed)
- speed_zone_table (28B), speed_calc_table (25B)
drive.rs simplified:
- open() calls init() instead of unlock()
- init() is the ONLY entry point — handles full dispatch sequence internally
- Removed read_config, read_register, maintain_speed, read_sectors from public API
- Added set_read_speed() for per-zone speed during content reads
- disc.rs updated to call init() instead of unlock()
Compiles clean, all tests pass.
Scans BDMV/JAR/*.jar class files for track label patterns:
eng_MLP_ → TrueHD, eng_ADES_US_ → Descriptive Audio (US)
dan_PGStream4 → Danish subtitles
Solves the "3x AC-3 English" problem — we identify Descriptive Audio, commentary, compatibility tracks.
Future: set MKV "visual impaired" flag automatically during mux.
Local only — needs more disc samples to validate before publishing.
