- load_files_multithreaded skips file_load_data when sendfile is active
- -f + -m works: sendfile bypasses loader, sender uses sendfile directly
- -f combined with -c or -s prints error and exits with rc=1
- Add Sendfile + Multithreading test case
- Add file_send_sendfile() using sendfile() syscall to send file
content directly from fd to socket, bypassing userspace memory
- Add use_sendfile field to Config struct (default false)
- Add -f / --sendfile flag parsing in client.c
- sendfile path in send_chunk() used when -f is set without -c or -s
- send_files_multithreaded() falls back to single-threaded when
sendfile is enabled (loader pipeline becomes unnecessary)
- Add Sendfile (-f) test case to test.py
- Replace env var control (FASTSYNC_SOURCE_DIR, FASTSYNC_DEST_DIR,
FASTSYNC_SAVE_TO_DISK) with explicit --source-dir, --dest-dir,
--save-to-disk CLI arguments
- Keep env vars as fallback for backward compatibility
- Fix test.py: split '-c 0' into separate args ['-c', '0']
- Fix test.py: throttled suite failed because systemd-run didn't
inherit env vars; now all settings are passed as CLI args
- Add env_name to exception/timeout result entries for correct display
- Fix scanner: when chunk fills up mid-directory, save DIR handle so
remaining files in that directory are not skipped (pre-existing bug)
- Fix -c -s: add STATUS_CHUNK to protocol, send it before chunk data,
handle it on the server side for both single and multithreaded paths
- Extract chunk_serialize/chunk_deserialize from chunk_compress/decompress
- Remove dead declarations (file_receive_from_buffer, etc.)
- Fix memory leak in receive_file_receive (free -> data_destroy)
- test.py generates ~50 MB of test data across bulk files
- All 8 integration tests + 7 unit tests pass
- test.py generates its own test files in test_data/ (small.txt, medium.txt,
binary.bin, nested subtree)
- source and dest directories configurable via --source-dir / --dest-dir
- verifies all transferred files match originals byte-for-byte after each test
- waits for server to finish before verification (fixes race in multithreaded)
- all test data lives under test_data/ and is cleaned up unless --keep-data
