- 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
- 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).
Add tests/integration/test_codecs.py (accept/reject matrix and byte
differential against rsync 3.4.1 for every algorithm), extend the
checksum/compression unit tests with MD4/SHA1/none vectors and per-codec
round-trips, pin the new config golden (2.26.0), and update the version
strings and codec acceptance expectations.
#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.
Split FastSync's single use_metadata bundle into four independent rsync-parity attributes: preserve_perms, preserve_times, preserve_owner, preserve_group. use_metadata is now a derived transport bit (config_derived_use_metadata).
CLI: real -p/--perms, -t/--times, -o/--owner, -g/--group plus --no-perms/--no-times/--no-owner/--no-group (short and long) and --no-preserve; -a is now rsync -rlptgoD; --preserve = -pt; -A implies -p; -X does not; --chmod implies -p; --usermap/--groupmap/--chown imply owner/group per side; --incremental/--delta still auto-preserve unless negated.
Receiver: per-attribute FileAttrPolicy gating for files, dirs (modes applied at end of transfer), symlinks and specials; rsync -E read-bit rule; new files get source_mode & ~umask sanitized (no group/other write); per-side identity resolution; deferred directory metadata; batch dir-metadata replay; daemon modules without 'client owner = yes' no longer refuse plain -a but force super off (no ownership) with a warning.
Wire: PROTOCOL_VERSION 2.21.0 -> 2.22.0 (four appended config bools, golden 653 / 95530566005420798). FileMetadata/chunk/batch framing unchanged. Docs/CHANGELOG/CMake updated to 2.22.0.
--dry-run now handshakes with a remote/daemon receiver and reports what
WOULD transfer/skip based on receiver state, mutating nothing on either
side.
- Serialize Config.dry_run into the wire config frame and append
STATUS_DRY_RUN_TRANSFER to the status enum (no renumbering); bump
PROTOCOL_VERSION/CMake VERSION/CHANGELOG/golden wire to 2.21.0.
- Receiver: receive_incremental_check_ex runs the normal read-only
decision and answers STATUS_OK (skip) or STATUS_DRY_RUN_TRANSFER
(would transfer) with no basis materialization/append/delta/full
transfer. All mutation sites are guarded by !dry_run: file store,
manifest deletes, --mkpath root creation, --delay-updates staging,
publication, directory-time application, and outcome acks.
- Client: send_dry_run_remote connects, sends the config, checks each
regular file and prints the would-transfer set + trailer; no file data
or delete manifest is sent. Plain local destinations keep the
client-side manifest.
Add the receiver-side --super / --no-super tri-state (Config->super_mode)
under the safe-subset + clear-refusal privilege model: FastSync never
elevates privileges, it only permits super-user attempts that are already
confined fd-relative below the authorized receive root.
- identity: privilege_super_permitted() gate (OFF=false, ON=true, AUTO follows
geteuid()==0); identity_apply_ownership/_link become no-ops when not
permitted; --super with no explicit identity policy implies raw numeric-id
preservation (explicit usermap/groupmap/chown/numeric-ids still win); warn
exactly once when --super is requested by a non-root receiver.
- file_receive: gate char/block device-node creation on the gate; FIFO/socket
handling is unchanged.
- wire: trailing super_mode int after the --iconv spec, validated 0..2 in
receive_privilege_options and validate_received_config; PROTOCOL_VERSION
2.17.0 -> 2.18.0; version-sensitive tests and docs updated.
- CLI: --super/--no-super parsed explicitly before the generic --no-* branch
(malformed --super=x rejected); usage text added.
- tests: config wire round-trip + invalid-value rejection, privilege-gate mode
unit test, CLI parse test, integration transfer + root-gated ownership
suppression/appliance tests.
- docs: RSYNC_COMPAT --super row + Wave E note, protocol mentions, README.
Wave D of Phase 7. Make -O/--omit-dir-times and -J/--omit-link-times real by
preserving directory and symlink times, and mark --secluded-args as an explicit
Impossible/Divergence no-op.
Wire: PROTOCOL_VERSION 2.16.0 -> 2.17.0. Adds a terminal STATUS_DIR_TIMES frame
(int count + (wire path, metadata) pairs) sent after all file data and the
optional delete manifest. STATUS_MKDIR also carries metadata for --dirs entries.
Config-frame layout is unchanged.
Sender: the recursive scanner captures every traversed source directory (both
DirectoryScanner and the parallel scanner root + workers, appends mutex-guarded)
into a shared list; the single-threaded and -m paths transmit it last.
Receiver: a DirTimeList accumulates received directory metadata and applies it
with fd-relative no-follow utimensat only at the very end -- after all children,
after the commit-style --delete, and after --delay-updates publication -- in the
single-threaded success frame and in server.c after the -m threads join. -O skips
the application. Symlink metadata is applied at link creation with
utimensat/fchownat/fchmodat AT_SYMLINK_NOFOLLOW; -J suppresses only link times.
identity_apply_ownership_link shares the identity resolver with the fd path.
Docs: -O/-J rows -> Implemented; --secluded-args -> Impossible/Divergence;
--protocol accepted/rejected values and Phase-6/7 notes updated.
Tests: unit (scanner dir capture, DirTimeList apply, symlink metadata, protocol
version values) and integration (dir mtime round-trip + -O, symlink mtime
round-trip + -J, independent suppression), parameterized over single/multithread.
