- Return clear error when Router is nil instead of panicking
- Capture and log sniffing.Sniff and xnet.Pipe errors at Debug level
- Move dial closure and Sniffer construction into HTTP/TLS switch branch
to avoid unnecessary allocation on non-HTTP/TLS traffic
- Merge ProtoHTTP and ProtoTLS cases, branch internally on proto
- Add doc comments on NewHandler and Handle
- Add comment explaining nil hop is valid (no forwarder config)
- Pass readTimeout to xnet.Pipe via WithReadTimeout
Fix bugs in the file handler: unbuffered send channel deadlock on Close,
conn leak when send drops on done, and Addr() returning nil. Add done-
priority select in send(), explicit ln.Close() in Close(), Unwrap() on
responseWriter for http.ResponseController, and nil guards.
Also add package doc, NewHandler doc, and 39 unit tests covering the
listener, responseWriter, handler lifecycle, auth, and file serving.
Fix bufpool leak when PackBuffer fails by extracting packResponse helper.
Add write deadline before conn.Write to prevent goroutine hangs on slow
clients. Log async exchange errors instead of silently discarding them.
Raise defaultBufferSize from 1024 to 4096 to match EDNS0 standard.
Deduplicate lookupHosts TypeA/TypeAAAA branches.
- entrypoint.go: guard ictx.RecorderObjectFromContext with nil checks on
ClientID and Redirect assignments
- io.go: fix CloseRead checking Writer instead of Reader, add Reader
fallback to CloseWrite, unwrap *readWriter/*readWriteCloser in
SetReadDeadline to reach underlying net.Conn
- docs: add package doc and exported symbol comments to internal/ctx
and internal/io
- Bump go-shadowsocks2 to v0.1.3 (new API symbols)
- Return error instead of nil when Target() is empty in TCP handler
- Reset wbuf unconditionally on write error to prevent unbounded growth
- Add nil guard on targetAddr before WriteTo to prevent panic
- Remove duplicate NewClientConfig call and dead ClientConfig literal
- Remove unused noDelay metadata field
- Fix buffer-size guard to catch negative values (len(b)==0 → bufSize<=0)
- Add address context to parse/session error messages
- Use write lock (Lock) instead of read lock (RLock) in CloseOnIdle since
it modifies the close channel, preventing a race with Close() that could
panic on double-close of channel.
- Buffer sniffingWebsocketFrame errc to capacity 2 and close both
connections on first error to ensure the remaining copy goroutine
unblocks and exits cleanly.
- Return errors from MasqueConn.Read/Write instead of silently
succeeding (prevents infinite busy-loops and silent data loss
if these methods are accidentally called).
- Set recorder Network field in protocol dispatch switch rather
than hardcoding "udp", so early errors don't misreport type.
- Clarify that DatagramConn context-ID handling only supports
context ID 0 (sufficient for CONNECT-UDP per RFC 9298).
The 30s hardcoded readTimeout in Pipe() caused all CONNECT tunnel
connections to be hard-closed after 30s of inactivity, breaking
WebSocket and long-polling connections through the proxy.
Pipe() now accepts a WithReadTimeout(d) option. When d is 0 (the
default) no read deadline is set, relying on TCP keepalives or context
cancellation to detect dead connections instead.
The HTTP handler exposes this as the idleTimeout metadata key.
Fixes: https://github.com/go-gost/x/issues/91
Implement UDP tunneling over HTTP/3 using HTTP Datagrams (RFC 9297):
- Add masque handler for server-side CONNECT-UDP
- Add masque connector and h3-masque dialer for client-side
- Add enableDatagrams option to HTTP/3 listener
- Add shared utilities for datagram connections and path parsing
Resource management and connection caching:
- Add deferred stream cleanup in connector on error paths
- Add IsClosed() and Close() methods to Client for proper session management
- Clean up stale cached clients in dialer before reuse
- Close underlying stream when DatagramConn is closed
- Move RequestStream opening from connector to dialer to enable dead
connection detection and cache invalidation (follows QUIC dialer pattern)
Extend MASQUE implementation to support TCP tunneling via standard HTTP/3
CONNECT method, in addition to existing UDP support via CONNECT-UDP:
- Add StreamConn type for TCP data transfer over HTTP/3 stream body
- Update handler to dispatch based on :protocol pseudo-header:
- "connect-udp" for UDP (RFC 9298)
- Empty/"HTTP/3.0" for TCP (RFC 9114)
- Add handleConnectTCP() using bidirectional stream relay
- Update connector to support both TCP and UDP networks
- Add connectTCP() for standard CONNECT requests
TCP uses :authority for target address and stream body for data.
UDP uses path template and HTTP/3 datagrams for data.
