Wave C moved 12 rows: -l/--links now real (was Partial). New Implemented (7):
--munge-links, -k/--copy-dirlinks, -K/--keep-dirlinks, -D, -A/--acls, -X/--xattrs
(links was Partial->Implemented). New Partial (5): --devices, --specials,
--copy-devices, --write-devices, --fake-super. Summary: Implemented 94->101,
Partial 6->10, Not Implemented 41->30 (Total 147).

Final Phase-4 summary: 101/3/10/3/30 = 147; PROTOCOL_VERSION 2.13.0.

Recreate char/block nodes via mknodat (privilege-gated, EPERM->warn+skip) and
FIFOs via mkfifoat; new STATUS_SPECIAL frame + validated rdev; sockets skipped;
-copy-devices copies st_size; -write-devices O_NOFOLLOW+O_NONBLOCK warn+skip.
preserve_specials/copy_devices/write_devices cross the wire. PROTOCOL_VERSION
2.12.0->2.13.0. Review fixes: -m source-removal keeps recreated specials, FIFO
ENXIO skip, rdev bounds at chunk_deserialize, STATUS_ERROR on receive branch,
scanner_prepare_special dedup.

Adds symlink-target transmission (File is_symlink+symlink_target, STATUS_SYMLINK
frame, chunk type 2), munge-links sender containment + receiver-side symmetric
target containment, keep-dirlinks confined dir-symlink following (O_NOFOLLOW
realpath-rechecked), and fixes -l to copy symlinks as symlinks. munge_links +
keep_dirlinks cross the wire; copy_dirlinks client-only. PROTOCOL_VERSION
2.12.0->2.13.0. Review fixes: receiver rejects absolute/.. targets, gated unmunge,
-K O_NOFOLLOW+re-fstat, keep_dirlinks set once at config-accept, rel_buf overflow
fails the walk.

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).

TapTap 0c4855e344 merge: resolve dev (quality refactor) into security-fixes
- 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
2026-09-01 20:46:07 +02:00
TapTap 6d82967c68 refactor: standardize error reporting on the log module
- 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

- Remove -DSTRICT_WARNINGS=ON from coverage job (_FORTIFY_SOURCE + -O0 + -Werror fatal)
- Fix chunk.c metadata guard: peek at present flag before calling metadata_from_buf
  so the remaining_size check covers the full sizeof(int)+FILE_METADATA_WIRE_SIZE
- Fix chunk.c UBSan misaligned loads: use memcpy instead of *(size_t*)deref
- Move srand(42) to test_property() top level so all property tests are seeded
2026-07-20 14:53:39 +02:00
TapTap a27f13d657 fix: bake CI deps into Docker image, fix chunk use_metadata OOB
- Build and push fastsync-ci:v8 with lcov, valgrind, clang baked in
- Remove all apt-get install steps from CI (v8 has them pre-installed)
- Fix chunk.c use_metadata=true OOB: add remaining_size guard before
  metadata_from_buf reads past the buffer. The bug allowed network-facing
  chunk_deserialize to heap-buffer-overflow on crafted inputs.
- Also guard against unsigned underflow on remaining_size - sizeof(int)

TapTap 7876721906 refactor: extract receive_chunk_data and receive_manifest shared helpers
- receive_chunk_data(fd, config) -> Chunk*: shared receive/decompress/deserialize
  (eliminates ~25 lines of duplication between server.c and multiprocessing.c)
- receive_manifest(fd, config, next_status): moved from server.c to file.c,
  fixes missing 'Deleting files not in manifest...' log in multiprocessing.c
- Removes redundant manual free loop in multiprocessing.c manifest handling
  (array_list_create(free) destructor already handles this)
- server.c and multiprocessing.c: remove local chunk/manifest helpers,
  remove compression.h include (no longer needed)

- Update tests for removed APIs
2026-07-16 12:08:09 +02:00
TapTap 02619cca5c refactor: split monolithic modules and extract shared components
- Remove dead socket.c/socket.h (accumulated duplicate symbols)
- Extract compression.h/c (data_compress/decompress from data.c)
- Extract io.h/c (low-level I/O from protocol.c)
- Extract metadata.h/c (unified metadata wire format from file.c, chunk.c, utils.c)
- Split client.c into client_cli.c (CLI parsing) + client_send.c (send logic)
- Move receiver pipeline threads from server.c to multiprocessing.c
- Move to_disk/file_restore_metadata from utils.c to file.c/metadata.c
- Fix const qualifiers on to_disk and str_dup signatures
- Suppress chown unused-result warning

- Remove unused config.use_single_send_per_file field
- Fix server_delete() no-op (double-pointer)
- Fix double cast (long)(long) -> ptrdiff_t in chunk.c
- Fix thread return value: thrd_error instead of 1
- Remove unused config param from receive_chunk_enqueue()
- Make queue_double_capacity() static
- Move SSH dest parsing into config.c as config_parse_ssh_dest()

TapTap 5fa0dc11e1 fix: address PR review comments
- Rename receive_file_receive -> file_receive (comment 62)

- Add NULL check after malloc in file_load_data (comment 66)
- Make chunk_serialize/chunk_deserialize metadata conditional on use_metadata param,
  thread through chunk_compress/chunk_decompress (comment 65)
- Add missing stdbool.h include to chunk.h
2026-07-05 20:45:34 +02:00
TapTap 4a1e666365 refactor: merge File/FileReceive, add optional metadata transfer with -M flag
- Remove FileReceive struct; use File everywhere with nullable FileMetadata*
- Remove struct stat from File; file size lives in Data->size (data_create_reserve)
- Add FileMetadata struct (mode, uid, gid, mtime) sent conditionally over wire
- Add -M / --preserve flag to client
- Restore permissions, ownership, timestamps on disk write
- Wire format uses per-file present flag for metadata (zero overhead when off)

TapTap c4aeed9f4d feat: implement chunk serialization protocol with -s flag
- Extract chunk_serialize/chunk_deserialize from chunk_compress/chunk_decompress
- Add STATUS_CHUNK to wire protocol for chunk-mode transfers
- Client: -s sends chunk via STATUS_CHUNK (serialized or compressed+serialized)
- Server: handle STATUS_CHUNK in both single-threaded and multithreaded paths
- Fix memory leak in receive_file_receive (free->data_destroy)
- Remove dead declarations: file_receive_from_buffer, file_receive_decompress,
  file_compress, chunk_data_to_disk, unused #defines
