TapTap 2ff51246c3 Update README and add feature tests for rsync-compatible flags 2026-07-16 13:31:43 +02:00
TapTap 284bf8f8bc rsync flags: -a, -n, -p, --exclude, --delete 
Feature changes across 15 files:

- -a/--archive: enables -c -m -M (no -s, which slows transfers)
- -n/--dry-run: scan + print without connecting or transferring
- -p <port>: custom SSH port (passed as -p to ssh via execvp)
- --exclude <pattern>: glob-based filename filtering in scanner
- --delete: sender collects file manifest; receiver deletes unlisted files

Protocol: added STATUS_MANIFEST, use_delete field in Config wire format.
New utilities: glob_match(), delete_extras() with recursive directory walk.
Scanner: accepts exclude patterns; skips matching entries.
SSH transport: switched from execlp to execvp for dynamic port arg.
Server + multiprocessing: handle STATUS_MANIFEST in both single and
multithreaded receive paths.

Builds clean, all 7 tests pass.

TapTap 52571bc960 streaming zstd: switch to ZSTD_compressStream2 / ZSTD_decompressStream 
Replaced one-shot ZSTD_compress / ZSTD_decompress with streaming
API (ZSTD_compressStream2 + ZSTD_decompressStream) in both
data_compress and data_decompress. Interface unchanged.

Prepares for true streaming transfer where compression can be
interleaved with transmission.

TapTap d1a23fc4df quick-wins: ControlMaster, -z alias, --progress, fix write warning

- Increased SSH socketpair buffer to 1MB via setsockopt (transport_ssh.c)
- Made chunk size configurable: new Config field, --chunk-size CLI flag,
  sent over wire, and used in scanner instead of DESIRED_CHUNK_SIZE
