- CLI: --append/--append-verify acceptance (parse + imply --incremental,
validate) and incompatibility rejection with -s and --whole-file; both
removed from the unimplemented reject list.
- Config: on-the-wire append/append_verify round-trip.
- Unit: append_resume_eligible / append_tail_length pure resume math.
- Integration (test_append.py): matching-prefix resume is byte-identical and
tail-only (wire bytes << source size); --append with a wrong prefix keeps
prefix+tail (rsync parity) while --append-verify detects the mismatch and
falls back to a byte-exact full transfer; --append with --inplace and -m.
- ignore-errors scan-error test now runs single-threaded and under -m (the
exact scan_directory_multithreaded path that had the use-after-free);
- new integration test: --delete/--delete-before --ignore-errors with an
unreadable SOURCE ROOT (sequential and -m) must fail and delete NOTHING;
- new integration test: a destination-only file that merely matches an exclude
rule is deleted under plain --delete (protection is sender-derived), while a
source-excluded mirror is protected;
- delete-protects/delete-excluded coverage extended to --delete-after and
--delete-delay;
- new unit test: the 100000-entry server hard bound is all-or-nothing (more
extras than the bound -> nothing removed);
- new integration test: --force is inert under --delay-updates (documented);
- fixed the ignore-errors assertion message that stated the opposite of what it
asserted.
Unit: walker all-or-nothing bounds (exceeded -> nothing removed + distinct
result; exact bound -> deletes), protected-prefix skipping, config wire
round-trip for force_delete/delete_excluded/prune_empty_dirs/max_delete, CLI
parse/validation for the new flags. Integration (TestDeletePolicy): default
delete-excluded protection and --delete-excluded opt-out (single-thread, -m,
early --delete-before, excluded-dir subtrees), --max-delete all-or-nothing over
and at the limit, --force file-over-nonempty-dir replacement, --prune-empty-dirs
(--dirs mode + recursion-mode parity), and --ignore-errors keeping deletion
active across a genuine scan I/O error (run as an unprivileged user).
