TapTap 864eb1316d Fix TLS code review issues: SSL cleanup, TLS 1.2 min, CA verify, deprecation guards, server --help, port validation, __thread io_ssl, shared accept loop 2026-07-18 17:39:37 +02:00
TapTap eff50346fd TLS transport: OpenSSL-based encrypted TCP
- New transport_tls.h/c: TLS server (server_create_tls, server_listen_tls)
  and client (client_connect_tls) using OpenSSL
- protocol.c: io_set_ssl() + SSL_read/SSL_write in send_n_data/receive_n_data
- transport_tcp.h: ssl/ssl_ctx fields added to Server/Client structs
- config.h/c: use_tls, tls_cert, tls_key fields
- client_cli.c: --tls, --cert, --key flags
- server.c: --tls, --cert, --key, -p flags with TLS support
- CMakeLists.txt: OpenSSL::SSL + OpenSSL::Crypto linkage
- shell.nix: openssl added to buildInputs

TapTap 46c650e9ae refactor: consolidate _no_path file send variants
CI / build-and-test (push) Successful in 26s
CI / build-and-test (pull_request) Successful in 26s
Add bool send_path parameter to file_send_single_calls and
file_send_sendfile, remove the _no_path variants. Callers in
client_send.c pass true (send path) or false (skip path) based
on whether an incremental check already transmitted the path.

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)
2026-07-18 17:19:12 +02:00
TapTap 5ed12f2bf0 refactor: deduplicate server receive logic, extract shared helpers
- Extract file_save_to_disk() helper (replaces 4x duplicated disk-save boilerplate)
- Extract receive_incremental_check() shared helper (deduplicates STATUS_CHECK
  handling between server.c single-threaded and multiprocessing.c multi-threaded paths)
- Break receive_files() into receive_chunk() and receive_manifest() sub-handlers
- Add incremental sync test case to test.py
- Rebase onto main

TapTap 1905369c9f Incremental sync: --incremental flag to skip unchanged files
- New STATUS_CHECK protocol status (value 6)
- Client sends path + size + mtime; server replies OK (skip) or NEXT (send)
- config.h/c: use_incremental field sent/received over wire
- file.c/h: file_send_single_calls_no_path helper for incremental path
- client_cli.c: --incremental flag
- client_send.c: per-file check before send in both single and chunk paths
- server.c: STATUS_CHECK handling in receive_files()
- multiprocessing.c: STATUS_CHECK handling in receive_thread()
- test.py: incremental sync test case

TapTap 4f8ae5bb70 fix: bw_tokens initialized to io_bwlimit, overflow check for --bwlimit 2026-07-17 10:07:18 +02:00
TapTap 3dcaf0b79d Fix bwlimit review: remove __thread (breaks -m), validate >0, handle nanosleep EINTR 2026-07-16 17:00:14 +02:00
TapTap 09a76e2a9a Bandwidth throttling: --bwlimit <KB/s> with token bucket
- protocol.h/c: io_set_bwlimit() + token bucket in send_n_data
  (64KB chunks, nanosleep-based deficit compensation)
- client_cli.c: --bwlimit <KB/s> flag
- test.py: bandwidth limit test case

TapTap efb98d8964 Multi-client server, protocol versioning, streaming decompression fixes 2026-07-16 13:59:41 +02:00
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 f778d1903c Merge pull request 'Streaming zstd: switch to ZSTD_compressStream2 / ZSTD_decompressStream' (#7) from streaming-zstd into main
Reviewed-on: #7
2026-07-16 12:31:49 +02:00
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 ca29109664 perf: downsized test data, increased SSH socket buffer, and made chunk size configurable
- Reduced test data from 50MB to 25MB (test.py)
- 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
- Fixed DESIRED_CHUNK_SIZE macro parentheses (chunk.h)

TapTap 660834d453 Merge branch 'main' into metadata-transfer, resolve conflicts
Conflicts resolved:
- config_create signature: added both use_metadata and use_sendfile params
- config_send/config_receive: wire protocol includes both use_metadata and use_sendfile
- client.c: config_create call updated, arg parsing includes both -M/--preserve and -f/--sendfile
- test_config.c: all three config_create calls updated
- file_send_sendfile: use file->data->size instead of removed struct stat
2026-07-05 20:29:04 +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 a48b3e3a17 refactor: pass use_sendfile to config_create 2026-07-05 16:38:13 +02:00
TapTap 01045d7d14 feat: add -f/--sendfile for zero-copy file transfer
- 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
2026-07-05 16:25:20 +02:00
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
