- Wire: config frame gains report_deletes (protocol 2.26.0 -> 2.27.0); the
receiver lists actually-removed paths in the STATUS_STATS path list, so the
sender prints rsync's `deleting PATH` / `*deleting PATH` lines for a real
--delete run (and -i/out-format). Observers threaded through the manifest,
missing-args and per-directory delete engines; golden wire len/hash updated.
- bwlimit: throttle now paces like rsync 3.4.1 -- ~100ms burst capacity and the
sleep is no longer credited as refill, so 4 MiB at 1024/2048 KiB/s matches
rsync within ~4% (was ~2x too fast).
The single-threaded and -m receivers never populated ReceiverStats.matched_data
or .deleted_files, so --stats always printed 0 for both even when rsync
reported nonzero. Track the bytes reconstructed from the basis file while
applying a delta, and tally the delete-commit counts (manifest and
per-directory sessions) into the receiver stats. The -m pipeline now carries
its own stats/would-delete fields and emits the STATUS_STATS frame before the
terminal success, so --threads finally reports the counters and renders
-n --delete lines.
Also normalize the -n --delete would-delete enumeration's absolute basis
prefixes exactly like the real commit path (fixing an over-report) and fix the
basis_delete_relative off-by-one when the receive root is '/'. Unit tests
cover the root mapping and the basis protection; integration tests cover
matched/deleted stats for both receivers and the --threads dry-run delete
lines.
Stream one delete plan per source directory from sender to receiver instead of
a single whole-tree keep-set manifest:
- --delete-during applies each directory's extras as its plan arrives, before
that directory's data (rsync's generator-order deletion).
- --delete-delay snapshots each directory's extras while the plan arrives and
commits the removals only after a fully-successful transfer, so files created
after the scan survive (matching rsync's delete-delay, not delete-after).
- Type conflicts (a destination file blocking a source directory, or vice
versa) are cleared immediately in both modes, so the nested write succeeds.
The plan carries the destination-relative directory, its kept child directory
names and its kept child file names; the first frame also carries the global
protected prefixes, size-skipped prefixes and --delete-missing-args paths.
--delete-before keeps the existing whole-tree early manifest; plain --delete and
--delete-after keep the end-of-transfer manifest commit.
Preserves the existing safety surface: protected/size-skipped prefixes and the
--delay-updates/basis skips are honored at any depth, deletion is scoped to the
synchronized directories (--files-from), MAX_SERVER_DELETE_COUNT and
--max-delete (partial + exit 25) are shared across plans, symlinks are never
followed, and paths are confined to the receive root.
- Scope the --delete extras walk to directories synchronized by the
transfer: add a synchronized-directory section to the delete manifest
(protocol 2.23.0) so --files-from subsets no longer delete untransmitted
paths outside listed directory subtrees (data-loss fix).
- Separate --max-size/--min-size prune protection from --delete-excluded so
size-pruned source mirrors survive (rsync parity).
- Unlink extraneous destination symlinks instead of skipping them.
- Make --max-delete partial (delete up to N, skip the rest) and exit 25;
accept negative values as unlimited.
- Draw --delete-missing-args deletions from the shared --max-delete budget.
- Honor --force during --delay-updates publication.
Add unit and integration regression tests; update the pinned config wire
golden and version strings for the 2.23.0 manifest/status additions.
