The Windows UI needs current winsafe, whose real minimum is 1.89 (its manifest
under-declares 1.87 while it uses NonNull::from_ref). Rather than stop at the
minimum, this goes to current stable and fixes what that costs.
The counter-intuitive result: 1.97 is CHEAPER than 1.89. libfreemkv had 54
clippy errors at 1.89 and 6 at 1.97, because clippy tightened the noisy
collapsible_if lint in between. Stopping at the minimum would have been the most
expensive choice available.
Roughly 47 lints across the eight repos, the large majority auto-fixed:
libfreemkv 6, freemkv-engine 14, bdemu 8, freemkv-keysources 7, autorip 6,
freemkv-unlock 3, freemkv-i18n 3. The hand-fixed ones are a descending sort to
sort_by_key(Reverse), four manual checked-division sites, a loop counter replaced
by enumerate, and a loop whose first let-else became a while-let.
Worth recording for whoever bumps next: clippy is MSRV-AWARE. Those 54 lints only
appear once the crate DECLARES 1.89 or later, because let-chains become
available. A bare `cargo +1.89 clippy` against a manifest still pinned at 1.87
reports clean and is meaningless — gate with the real precommit script, which is
also the only thing that covers build scripts.
The pin still sits below the Mac default, so it keeps doing its job: catching
lint drift locally before CI sees it.
The Windows UI needs winsafe, whose current release requires rustc 1.87. The
alternative was pinning winsafe back to an older release, which would bake a
stale API surface into a brand-new UI permanently to dodge one minor version.
The pin's purpose is to sit BELOW the Mac default so clippy drift is caught
locally before CI, not to stay on 1.86 specifically, so 1.87 preserves the
discipline exactly.
Verified before moving anything, not after: `cargo +1.87 clippy -- -D warnings`
and `cargo +1.87 fmt --check` are clean across all eight repos, and the full
precommit gate (fmt + clippy + tests) passes on libfreemkv, autorip, bdemu,
freemkv-engine and freemkv-keysources. Zero new lints, zero formatting drift.
Disc::sweep, Disc::patch, Disc::copy, SweepOptions and PatchOptions have
zero occurrences in src/ — recovery moved to freemkv-engine — but they were
still documented in 30 places across README.md, TROUBLESHOOTING.md, six
files under docs/, seven src/ doc comments and a Cargo.toml comment.
README.md is the crate's GitHub front page and carried a full multi-pass
code example that cannot compile.
Two of the src/ references were intra-doc LINKS to deleted items
([`disc::Disc::copy`], [`disc::Disc::patch`] in scsi/mod.rs). They produced
no warning on a normal `cargo doc` only because they sit on pub(crate)
items; `--document-private-items` reports both, and they are gone now.
The README example is deleted rather than rewritten against the engine's
API: libfreemkv documenting a downstream crate's API on its own front page
is the drift that produced this, and it cannot even depend on it. The src/
references become plain code spans naming freemkv_engine::recovery::* —
deliberately not links, for the same reason.
docs/rip-recovery.md was 202 lines about relocated code. It now documents
only what this crate owns — Drive::read, SenseFamily, DiscStream's adaptive
batch halving — plus the read-path design constraints, which belong with the
code that enforces them, and points at freemkv-engine/src/recovery/ for the
strategy. api-design.md's module tree is regenerated from the real src/disc/
and src/drive/ layouts instead of hand-patched; it had listed sweep.rs,
patch.rs, mapfile.rs and read_error.rs, none of which exist.
Three stale facts surfaced while rewriting and are corrected: the read
timeouts are 10 s / 60 s, not the documented 1.5 s / 30 s; Drive::reset and
SgIoTransport::reset no longer exist at all, so "no SCSI reset from any read
path" is now stated as the stronger fact it has become; and verify_title,
listed as a progress-emitting operation, was removed entirely.
CHANGELOG.md keeps its references — those are the historical record of the
releases that shipped the API.
The sweep/patch recovery strategy, mapfile, retry-decision state machine,
section-recover, and damage classification move out of libfreemkv into the
new freemkv-engine crate. libfreemkv keeps the raw single-shot read and
SCSI-fact translation (SenseFamily stays in scsi).
- Delete disc/{sweep,patch,mapfile,read_error,section_recover}.rs, the
Disc::copy/sweep/patch methods, the Copy/Sweep/Patch option+result types,
classify_damage/DamageSeverity, progress_snapshot_from_mapfile, and the
three recovery integration tests.
- Trim public surface the recovery deletion orphaned: delete the dead
READ_PIPELINE_DEPTH const, the write-side SectorSink/FileSectorSink (no
consumer), and the DriveSpeed enum (its one live use — set max drive
speed — becomes Drive::SPEED_MAX_KBPS). Make mapfile_path_for,
decrypt_sectors_mapped pub(crate); gate NoopEvents to test.
- Version 1.6.0.
The last release left this pinned to the git tag v1.5.1; release.sh expects
a committed path dep on the branch tip (it swaps path -> git tag only in the
tagged commit, matching bdemu). Restores that state so a local full-workspace
build links the sibling freemkv-unlock, and release.sh's path->tag swap works.
A CSS DVD whose main title was mis-detected as unencrypted (the up-front
crack scanned the largest cell first and starved its budget in that cell's
clear prefix) muxed scrambled sectors as plaintext at exit 0. CSS leaves
the pack/PES header clear, so an un-descrambled sector muxes as a
structurally-valid but corrupt PES packet with zero loss reported.
decrypt_keys_for_title resolves a DVD title's CSS key two ways:
- Fast path: reuse the scan's cracked key when its crack_span covers this
title's VTS (no re-read; on a live drive no second bus-auth).
- Crack: on a detection miss or a different VTS, crack from the title's OWN
extents in a SINGLE scan in natural PLAYBACK ORDER (never largest-first).
One scan = one CSS-locked early-bail, so a locked title is not re-hammered
per cell against a live drive (hard rule #2); the 50k-sector budget is the
same accepted bound the disc-wide scan uses. Cracked -> key; Unencrypted
-> clear; ScrambledUncracked -> hard-fail.
ensure_title_decryptable hard-fails an uncrackable DVD title even when
detection missed, and passes a title that resolved its OWN valid key
regardless of the disc-wide css_error. descramble_region is unchanged from
v1.5.1 (validated-key seed).
Also rename the unlocker report's DVD entry CSS -> DVD. Bump 1.5.2.
Add UnitKey.variant_number (0 = ordinary, 1..32 = forensic variant) with new/variant constructors, and aacs::variant_select — resolve a disc's single variant and classify each aligned unit (default / variant / drop foreign / conceal keyless). Correct IndividualSegment.tbl: the per-record field is the variant (cycles 1..32 on a retail disc), not a segment number — Segment.number -> Segment.variant.
Relicensed from AGPL-3.0 to MIT, effective 1.3.1 (<=1.3.0 remain AGPL). The CSS
content cipher and Stevenson title-key attack are attributed to their published
cryptanalysis (not libdvdcss); all libaacs/libbluray/libdvdread/libdvdnav name
references were dropped from comments while keeping the standard format/spec
descriptions. Also bumps to 1.3.1.
Parse ADV_OBJ/VPLST000.XPL (the real HD-DVD player playlist) with roxmltree
into one DiscTitle per <Title>: its PrimaryAudioVideoClip clips in order (EVO
via the .MAP sidecar), the titleDuration, the displayName, and the ChapterList.
A layer-break split (FEATURE_1+FEATURE_2, feature/feature_Divide) composes into
ONE title with the two parts as clips, each carrying its title-time in/out
points (45kHz ticks) for seamless-join splicing. Falls back to the clip-name
heuristic when no playlist is present.
Fixes unknown runtimes (real durations), poor names (FEATURE -> 'Main Movie'),
and gives authoritative composition + chapters. Validated on ANCHORMAN (97m),
SHAUN (99m), HARRY_POTTER (152m).
Bump to 1.3.0 and add the 1.3.0 changelog entry (FMTS/HD-DVD formats, AACS 2.1 variant chain, recovery seam, aacs module split, main-title-by-size, and the fixes since v1.2.2). Not tagged or pushed.
Adopt freemkv-unlock's split Unlocker trait: run_features drives the drive-prep capability, run_bus the content bus removal, each iterating unlockers until one doesn't decline (NotApplicable = try next; Ok or a real error stops).
unlocker_matrix now reports which drive-prep unlocker actually ran — LibreDrive removes the bus at the drive; Renesas unlocks features but leaves the bus to the cert. Wire product_id through to fu::DriveId.
Bump to 1.2.3.
libfreemkv now git-deps freemkv-unlock (which carries drive firmware and can
never be on crates.io), so libfreemkv itself can only be consumed by git tag.
The freemkv-unlock dep stays an interim path dep for local cross-repo dev; the
release script swaps it to a git tag in the tagged commit.
Add the freemkv-unlock dependency (path dep for local dev; re-pinned to a git
tag at release) and the consumption bridge: one generic ScsiAdapter mapping
libfreemkv's transport to the unlock contract, host-cert + DriveId mapping, and
run_unlockers() which news up all_unlockers() and runs the first matching one.
Additive — validates the dep resolves and the adapter compiles; the in-tree
registry/handshake/css path is still active and gets replaced in 4b.
keydb I/O moves out of libfreemkv into freemkv-keysources
(KeydbSource::save / ::update). Delete src/keydb.rs entirely (save,
http_get, default_path, write_atomic, UpdateResult) and drop `pub mod
keydb;` — http_get had no real callers. The shared Keydb* Error variants
stay in error.rs (keysources raises them; the every-error-has-a-code
contract depends on them). flate2 is no longer used here, so drop it
from Cargo.toml (zip stays for labels/jar.rs).
CHANGELOG: note the keydb-I/O move; reword the rc.5.2
DefaultDecodedFieldDuration entry to state only the action taken (the
revert) rather than an unverified Windows-fps outcome.
