Adds a unit test proving the config-only STATUS_DELETE_PLAN frame applies
--delete-missing-args exact deletions while walking no directory (the
--files-from-with-no-synced-dir fix).
- receiver stats: exclude basis-dir materializations (--link-dest/--copy-dest)
from created/literal tallies; rsync reports 0 for a basis hit, so a fresh
--link-dest --stats run now matches (differential test_link_dest_stats_matches_rsync)
- filter wire block: reject a pattern above the glob evaluation bound and lower
MAX_FILTER_RULES to 1024, so a crafted rule list cannot amplify delete-walk
glob work or install a rule that silently never protects
- negative tests for over-cap count and over-long pattern
- README: correct --delete default, --stats/--progress description, add
--delete-commit; RSYNC_COMPAT stale version labels/overclaim fixed
- plain --delete with no timing flag now selects delete-during (progressive
deletion, matching rsync and avoiding the full old+new tree peak)
- new long-only FastSync --delete-commit restores the old atomic behavior
(delete only after the whole transfer succeeds); timing-identical to
--delete-after, implemented via the same wire bool
- timing flags are mutually exclusive; --delete-commit conflicts with other
timings; --delete-before/--delete-during rows reworded per Phase-0 probes
- CHANGELOG migration note; tally unchanged 116/14/27
Probe shows the candidate choice is observable only as --stats bandwidth
counters (tree/exit always identical). FastSync already uses rsync's
fuzzy_distance/find_filename_suffix name heuristic; the residual is the
narrower delta eligibility window (>=16 KiB, <=10x) vs rsync's wider one.
Row -> caveat; tally 116/14/27.
Adds the exclude_protect_dest_only differential and flips --delete-excluded
to parity now that receiver-side rules protect a destination-only excluded
entry like rsync; tally 116/10/31.
- new bounded config-wire block (BLOCK_PROTECT_RULES) serializes the sender's
compiled filter rules to the receiver (bounded count + 256 KiB patterns;
strict action/sides validation)
- receiver evaluates protect/risk in the whole-tree extras walk and the
per-directory delete plans, so a dest-only entry matching 'P' is kept like
rsync; dry-run would-delete enumeration also honours it
- --filter flips to parity (115/11/31); per-dir merge receiver re-derivation
remains the documented residual
Probe shows the block-checksum choice is not observable in the parity surface:
%c, Matched/Literal data and the destination tree are invariant across
xxh64/xxh128/xxh3/md5/md4/sha1 and the transfer,pre-transfer form; only %C
changes, and it is byte-identical to rsync. FastSync's fixed xxHash32 block
strong sum is collision-safe within the payload cap. Row -> parity (114/11/32).
- when --progress/--info=progress is requested, a metadata-only pre-scan
builds the full file-list total and directory names so the to-chk
denominator counts every regular/dir/link/special entry like rsync
- per-directory/symlink/special name lines emitted; sequential and --threads
- reuses the --delete-during/delay pre-scan when present; non-progress runs
take no extra pass
- --progress stays a caveat (emission order still differs); single-file output
remains byte-identical
- PROTOCOL_VERSION 2.27.0 -> 2.28.0; STATUS_STATS gains literal_bytes and
the created reg/dir/link/special counters (golden wire updated)
- receiver reports which destination entries it newly created, including
implicitly-created parent directories below the logical transfer root, so
Number of created files carries rsync's per-type breakdown
- Literal data is now exact for a delta transfer (receiver counts the literal
fragments it stored)
- differential-tested vs rsync 3.4.1 for fresh-create, update and delta
- -n/--delete sends the same protected/size-skipped/scope as a real run, so
the read-only would-delete walk no longer over-reports (row -> caveat)
- --delete-delay charges --max-delete on actual removals and recursively
re-scans a refilled deferred directory at commit; independent deferred cap
- --info=name emits the leading ./ root line and name2 'is uptodate' lines
- differential tests promoted from residual pins to rsync parity assertions
