Add test_out_format_c_delta_mode_divergence documenting that FastSync's
delta %c (its own handshake bytes) cannot match rsync's (16-byte sum header
plus per-block checksums); only the whole-file case is aligned. The test
pins both values so a future parity improvement is noticed.
- Output parity: add `File list size` to the strict --stats differential and
document the row-#3 residual with test_stats_file_count_breakdown_residual
(rsync's `Number of files`/`Number of created files` type breakdown is not
reproducible from what the sender knows: no directory accounting and no
per-entry destination-created state). The row stays a caveat.
- Add --threads variants for the --stats and --progress/-P differentials.
The `-n --delete --threads` variant is a documented xfail: the threaded
dry-run path does not consume the receiver's STATUS_STATS delete list yet.
- Replace the 0.2s sleep flake in the delete-timing proxy with a socket
barrier: the hook now fires only after the server sends a reply (proving it
processed the preceding per-directory delete plan), using --incremental +
--ignore-times to guarantee a mid-transfer handshake reply.
rsync's %c counts the block-checksum bytes received: even a whole-file
transfer with no basis receives rsync's 16-byte sum header (append and
inplace included), while a dry run receives nothing. FastSync's
whole-file path has no equivalent header, so report 16 for parity when
delta is inactive, keep 0 for dry runs, and keep the real received bytes
when delta is active (FastSync's signature framing differs, so delta %c
stays divergent). Add a strict %c/%l/%n differential against rsync and
turn the %b check into a real rsync differential (semantics: both count
wire bytes and exceed %l; the exact values are protocol-specific).
Replace the aggregate stderr progress with rsync 3.4.1's per-file progress
block (name, 32 KiB first frame, final frame with (xfr#N, to-chk=X/Y)).
Add differential tests against real rsync for --out-format %C/%b, the
--progress frames, selected --stats lines and -n --delete lines.
#291:
- Compile --exclude/--include/--exclude-from/--include-from into the SAME
ordered rule list as --filter/-f (first match wins), so the common
`--include='*.txt' --exclude='*'` idiom and include-alone semantics match
rsync. The legacy per-kind scanner arrays are no longer applied.
- -x/--one-file-system emits the cross-device mount-point directory entry
(empty) instead of dropping it, in both the sequential and parallel scanners.
- Stop passing the legacy arrays to the scanner; document -f is --filter.
#292:
- New src/shared/format.c/.h: rsync "big_num" (comma-grouped integers) and
decimal -h human sizes, %M/%t timestamp, and the STATUS_DEST_INFO codec.
- Receiver answers each STATUS_CHECK with a pre-transfer destination snapshot
(new report_dest_info wire field + STATUS_DEST_INFO, PROTOCOL_VERSION
2.23.0) so the sender can render true itemize columns.
- Itemize now emits rsync-correct update/type chars and c/s/t/p/o/g columns
for files, dirs, symlinks and hard links, comparing size/time/perms/owner/
group against the reported destination.
- --out-format gains %i %n %f %l %b %M %t %o %p %B %U %G %L; %f is the
relative display path, %M the YYYY/MM/DD-HH:MM:SS form, %b the literal
bytes sent.
- --list-only prints transfer-relative names, directory entries and ls-style
grouped sizes.
- --stats prints rsync's multi-line block on stdout; -h uses decimal units.
Tests: unit tests for the filter ordering, format primitives, itemize
columns; integration + differential tests against real rsync 3.4.1 for
itemize/out-format/list-only/selection and -x. Golden wire len/hash and
protocol version strings updated for 2.23.0.
