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.
#289 checksum/compression:
- -c/--checksum now implies the incremental content quick-check (without
implying -t), so an unchanged file is skipped like rsync.
- --checksum-choice/--cc accepts xxh64/xxhash, xxh3, xxh128, md5 and auto;
md4/sha1/none and the two-name form are rejected by name.
- --compress-choice/--zc rejects lz4/zlib/zlibx by name (zstd/none/auto kept).
- --checksum-seed=0 is randomized per transfer and sent on the wire.
- --skip-compress uses rsync 3.4.1's default suffix list; slash separators and
dot-less suffixes are accepted.
- add --no-whole-file.
#295 timeouts/alloc/temp-dir:
- --timeout default 0 (disabled), --contimeout default 60; 0 disables both,
plus --no-timeout/--no-contimeout.
- --max-alloc=0 means no allocation limit (was rejected).
- --temp-dir accepts any dir, requires it to exist, and falls back to a
non-atomic copy on EXDEV instead of aborting.
#296 connectivity/daemon:
- -M/--remote-option is rejected for daemon/TCP destinations (SSH-only).
- --trust-sender clarified as receiver-local; server-path tests added.
- --stop-at accepts rsync's full date form (y-m-dTh:m etc.).
Adds unit and integration coverage; no wire-field change, PROTOCOL_VERSION stays
2.22.0.
- client_cli: capture errno before output_escape() in
read_patterns_from_file() so an over-long line is still reported as
EFBIG instead of the (possibly malloc-clobbered) errno.
- file_list: guard string_list_add() capacity doubling against
overflow (capacity > INT_MAX / 2), matching filter_rule_list_add();
callers already surface the false as a memory-allocation error.
- compression: ZSTD_isError() is true for ZSTD_CONTENTSIZE_UNKNOWN,
which made the 3x unknown-size fallback dead code. Test the
CONTENTSIZE_ERROR/UNKNOWN sentinels explicitly so unknown-size frames
reach the estimate path (still bounded by the existing hard limit)
while invalid frames are rejected. Known-size frames and the 100 MB
ceiling/overflow checks are unchanged.
- tests: add an unknown-content-size-frame decompression test.
Tests: ./build/tests and ./build-asan/tests all pass (42/42);
clang-format + cppcheck clean.
data_decompress_limited() looped while ZSTD_decompressStream() returned a
positive hint. A truncated frame keeps returning that hint with all input
consumed, so a malformed/truncated payload spun forever (CPU DoS). Detect
input exhaustion with an incomplete frame and fail via the existing cleanup,
skipping the check when the output buffer merely needs to grow first.
Add a fork+alarm regression test that truncates a valid frame and asserts
decompression returns NULL promptly.
- 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
- Reformat all C/H files to match .clang-format (LLVM style)
- Fix 26 cppcheck const-correctness warnings (constParameterPointer,
constVariablePointer, constVariable)
- Update function declarations in headers to match const parameters
- 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)
