ginuerzh	722dde5cfc	fix(handler/forward): split readTimeout from pipe idleTimeout to prevent 15s download abort ... The readTimeout field (default 15s) was being applied via xnet.Pipe to both directions of a bidirectional proxy connection. During asymmetric transfers (e.g. HTTP file download), the direction reading from the tunnel sees no data after the initial request is forwarded, causing SetReadDeadline to fire after 15s and abort the entire transfer. Fix: add a separate idleTimeout field (default 0=disabled) to the metadata structs in both forward/local and forward/remote handlers, and switch xnet.Pipe to use idleTimeout instead of readTimeout. The readTimeout field now only applies to the initial protocol sniffing/handshake phase. Also document readTimeout vs idleTimeout semantics across all 24 locations in the x/ module where these timeouts appear: - readTimeout: handshake sniffing deadline (handlers), upstream response header timeout (http.Transport), or transport-level read deadline - idleTimeout: idle read deadline per Pipe direction (0=disabled) - ReadTimeout on Sniffer/SnifferBuilder: upstream response header/TLS handshake read timeout during sniffing	2026-05-31 17:05:21 +08:00
ginuerzh	f8ddb193cb	refactor(handler/forward/remote): split handler into 6 focused files with 41 tests ... Split the 339-line handler monolith and 1169-line test blob into 11 files (5 source + 6 test) following the handler/forward/local/ pattern. Source files: handler.go (core), forward.go (raw forwarding), sniffing.go (SnifferBuilder + protocol dispatch), util.go (errors + recorder + rate limit), metadata.go (config parsing). Fixes: add sync.Mutex for hop access (race), use sentinel errors for errors.Is compatibility, add nil-addr guard in checkRateLimit, reuse SnifferBuilder via Build() instead of per-call construction.	2026-05-30 16:27:20 +08:00
