After Tor 0.4.3.0-alpha-dev successfully established a TCP connection with a bridge but failed to finish its handshake, it sends the following `STATUS_CLIENT` message to the controller: ``` 650 STATUS_CLIENT WARN BOOTSTRAP PROGRESS=10 TAG=handshake_dir SUMMARY="Finishing handshake with directory server" WARNING="DONE" REASON=DONE COUNT=1 RECOMMENDATION=warn HOSTID="0000000000000000000000000000000000000000" HOSTADDR="[scrubbed]" ``` One can reproduce this by using torproject.org's web server as a bridge: 95.216.163.36:80. The substring `WARNING="DONE"` is misleading and should – if I'm interpreting [control-spec.txt](https://gitweb.torproject.org/torspec.git/tree/control-spec.txt#n2682) correctly – contain a human-readable description of what went wrong. Other `STATUS_CLIENT` messages do a better job; for example: ``` 650 STATUS_CLIENT WARN BOOTSTRAP PROGRESS=5 TAG=conn_dir SUMMARY="Connecting to directory server" WARNING="Connection refused" REASON=CONNECTREFUSED COUNT=1 RECOMMENDATION=warn HOSTID="0000000000000000000000000000000000000000" HOSTADDR="[scrubbed]" ``` Here, the substring `WARNING="Connection refused"` gives me a good idea of what's going on. I suggest to fix the warning in this particular error case.
