- Fix dead-code branch in bind.go host assignment (always use endpoint hash)
- Return descriptive error on bypass match in connect.go (was masking as success)
- Update bypass test in connect_test.go for new error behavior
- Extract entrypoint subpackage from monolithic entrypoint.go (6 files)
- Fix observeStats event-loss bug (break -> fallthrough on retry success)
- Add 47 unit tests across handler, connect, bind, metadata packages
- Add architecture doc comments to all key files
- Build and vet clean, 173 tests pass with -race
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
