- Adaptive probe algorithm in Disc::copy skip_on_error mode: after 4
consecutive errors, probe 1 sector at 256x batch (8 MB) ahead. If
good, zero-fill gap, mark NonTrimmed, jump. Clears bad zones in
seconds instead of hours.
- NOT_READY sense key (0x02) now retries up to 3x with 3s pause before
marking NonTrimmed. BU40N returns NOT READY for bad sectors, not
MEDIUM ERROR.
- PassProgress struct gains bytes_bad_total field for consumer-side
bad/retryable byte counts.
- Mapfile header version string fix: no longer duplicates 'libfreemkv v'
prefix on each write.
- Structured sense_key/asc/ascq logging in copy error path.
Pre-0.13.16 the rip API leaked internal mapfile concepts (pos,
bytes_good, work_done, bytes_pending, Finished/NonTrimmed) into per-pass
positional callbacks Fn(u64, u64, u64). Consumers reinvented the math
each time, and v0.13.15's UI bug surfaced exactly because of this —
autorip's web JS computed pct from bytes_good while the backend
computed from pos, silent drift, frozen UI bar.
This release replaces both Disc::copy::on_progress and
Disc::patch::on_progress callbacks with a single Progress trait +
PassProgress struct (new progress module).
pub struct PassProgress {
pub kind: PassKind, // Sweep | Trim {reverse} | Scrape {reverse} | Mux
pub work_done: u64,
pub work_total: u64,
pub bytes_good_total: u64,
pub bytes_total_disc: u64,
}
pub trait Progress {
fn report(&self, p: &PassProgress);
}
impl<F: Fn(&PassProgress)> Progress for F { ... } // closures work directly
CopyOptions::on_progress and PatchOptions::on_progress are renamed to
progress: Option<&dyn Progress>. Closure callers update trivially via
the blanket impl; struct callers gain a clean named-field shape with no
positional-arg confusion.
PassKind carries the semantic (sweep vs trim vs scrape vs mux) so
consumers can label phases without reinventing detection logic.
Disc::patch reports Trim {reverse} for retry passes with block_sectors
>= 2 and Scrape {reverse} when block_sectors == 1. Direction comes
through reverse: bool. Mux variant is reserved for v0.13.17 when the
mux pipeline emits progress.
Tests + clippy clean across all 4 crates.
