Capture+transmit source atime (pre-read stat; O_NOATIME sender guard) and birth
time (statx STATX_BTIME); receiver restores atime with mtime (crtime not settable
portably -> transmitted, explicitly not applied). --open-noatime is client-only.
-O/-J documented as accepted no-ops (FastSync never preserves dir/symlink times).
Wire: metadata frame gains atime/crtime val+sec+nsec; PROTOCOL_VERSION
2.11.0->2.12.0. Review fixes: gate atime capture to Linux (no epoch clobber on
non-Linux), close fd on fdopen failure, honest -O/-J status (Compat no-op).
RSYNC_COMPAT Phase-2 row M: path-list construction and destination
directory creation while preserving traversal safety.
- -R/--relative with --files-from: transmit each listed entry under its
bare relative destination path (no source-root mirror). Files keep an
absolute local read path plus a separate wire/dest path (File.send_path);
manifest, incremental quick-check and change output follow the wire path,
so --delete and --remove-source-files stay consistent. -R without
--files-from is unchanged (full mirror).
- --no-implied-dirs: client-only, only meaningful with -R + --files-from.
A listed file whose parent dir is not itself (or via an ancestor)
explicitly listed cannot be placed; the run fails up front with a clear
error. No effect otherwise.
- --dirs/-d + --old-dirs/--old-d aliases: -d <dir> transmits the source
root as an explicit empty directory entry (STATUS_MKDIR frame); with
--files-from listed dirs are created empty and listed files transferred,
never descending. Works single-threaded, -m (sequential scanner in the
-m scan thread) and chunk-serialization (per-file type marker).
Directory entries appear in the delete manifest.
- --mkpath: new wire bool; server creates the destination root (and missing
leading components under its authorized root) at connection start. A
missing destination root is now rejected by default.
- Protocol bumped to 2.7.0 (mkpath wire field + STATUS_MKDIR + chunk type
marker). All receive paths funnel through file_save_to_disk_full which
creates directories via the secure confined mkdir engine; dir entries are
excluded from --remove-source-files outcome acknowledgements on both ends.
- Unit coverage: CLI parse (relative/dirs aliases/mkpath/no-implied-dirs),
config round-trip (relative + mkpath), scanner --dirs non-recursion and
-R send_path (sequential + parallel), receiver dir-entry save.
- Integration coverage: TestRelativeFilesFrom, TestNoImpliedDirs, TestDirs,
TestMkpath (single and -m).
- RSYNC_COMPAT: 4 rows move to Implemented (Summary 67/3/5/1/71 = 147).
The Phase 1 merge conflict resolutions introduced formatting that failed
the CI lint job (clang-format 18.1.3). Reformatted with the exact CI
version; no functional changes.
- file.c split layout retained; security-hardened secure-fs helpers
(open_secure_parent/to_disk_secure/rename_secure/stat_secure) now live in
file.c with file_ prefix and are shared with file_receive.c
- file_receive.c takes the security branch's bounded allocations
(receive_data_limited, data_decompress_limited, size checks) and
STATUS_ERROR signaling
- file_send.c gains the data consistency check on file->data
- client_validation.c: stricter --tls requiring --ca, log_message style
- utils.c: hardened openat/mkdirat mkdir_r from security branch
- Add log_perror() helper (context + strerror(errno)) to the log module
- Replace all bare perror() calls with log_perror() so errors are routed
through the unified logger (stderr sink + optional --log-file sink)
- Convert fprintf(stderr, "Error:/Warning: ...") in client code to
log_message(); raw fprintf kept only for progress/stats output
- file.c: File/FileMetadata lifecycle and local disk helpers (~110 lines)
- file_send.c: client-side send path (file_send_single_calls, file_send_sendfile)
- file_receive.c: server-side receive/save path (file_receive, receive_incremental_check,
receive_manifest, file_save_to_disk)
- file_types.h holds shared struct definitions; file.h remains an umbrella header
so existing includes are unaffected
