- 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
- Return err instead of nil in SS TCP/UDP connector Init when
NewClientConfig fails, preventing nil pointer dereference in WrapConn
- Initialize tcpClient in UDP connector for UDP-over-TCP path
- Add decodeSIP002Auth to handle ss://BASE64(method:password)@host:port
URL format with RawURLEncoding and StdEncoding fallback
- Update buildServiceConfig and buildNodeConfig to decode SIP002 auth
for ss* schemes before falling back to standard userinfo parsing
- Support RawURLEncoding in parseAuthFromCmd with StdEncoding fallback
- Add tests for decodeSIP002Auth, parseAuthFromCmd, and integration
tests for buildNodeConfig/buildServiceConfig
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.
