First real code in daemon/. veloxd now listens on
$XDG_RUNTIME_DIR/velox/velox.sock (0600, SO_PEERCRED same-UID check),
frames NDJSON, and routes every method through the generated
velox::proto::dispatch(). The CLI and GUI have a server to talk to.
Modules:
- rpc/ndjson.hpp — newline-delimited framing, 8 MiB frame cap, CRLF-
tolerant, partial-tail buffering. Header-only, tested.
- rpc/event_loop — single-threaded poll(2) reactor; never blocks the
loop. stop()/wake() are async-signal-safe (eventfd).
- rpc/runtime_dir — $XDG_RUNTIME_DIR/velox resolution, 0700, owner-checked;
refuses an insecure fallback rather than using /tmp.
- rpc/uds_server — listener + non-blocking per-conn read/write with
backpressure; handles session.hello (protocol-major
check -> -32001, sessionId, transport=uds) and
session.subscribe in the server layer; routes the
rest through dispatch().
- rpc/dispatcher — VeloxDispatcher : proto::Dispatcher, all 39 methods.
download.list answers an empty table; the rest return
"not implemented" (-> -32603) until the store lands.
- main.cpp — abstract-namespace single-instance lock, signal ->
clean shutdown, socket unlinked on exit.
Tests (ASan+UBSan and TSan clean):
- veloxd.ndjson — framing edge cases
- veloxd.uds_roundtrip — real socket: hello ok / version mismatch / empty
list / -32601 / -32700 / pipelined requests, and a
guard on the -32603 collapse documented in P1.
Known gap, filed not worked around: daemon/docs/proto-requests-m1.md P1 —
the generated Dispatcher has no error channel below -32603, so handlers
cannot yet return -32010/-32011/-32013 with their data payloads. The
server layer handles -32001/-32002/-32003 around dispatch(); genuine
in-handler errors collapse to -32603 until PROTO gives handlers a real
error return. Three error fixtures are non-conformant until then.
Not in this drop: rpc/ws_server (next; needs the store for hashed pairing
tokens), store/, sched/, cli/. WS reuses this event loop.
