Comment:
This is key:
{{{
Jun 21 19:22:56.000 [err] circuit_get_open_circ_or_launch(): Bug:
Connection state mismatch: wanted AP_CONN_STATE_CIRCUIT_WAIT, but got 6
(waiting for rendezvous desc)
}}}
And so is this:
{{{
#2 circuit_get_open_circ_or_launch (conn=conn@entry=0x612000246dc0,
desired_circuit_purpose=desired_circuit_purpose@entry=7 '\a',
circp=circp@entry=0x7fffed22fe30) at src/or/circuituse.c:1841
#3 connection_ap_handshake_attach_circuit
(conn=conn@entry=0x612000246dc0) at src/or/circuituse.c:2425
}}}
Note that when we first entered connection_ap_handshake_attach_circuit,
conn->state was CIRCUIT_WAIT, since otherwise the assertion at the start
of connection_ap_handshake_attach_circuit would have failed. Also, the
second invocation of circuit_get_open_circ_or_launch is hitting the
assertion. The first invocation must have returned 0. Finally, somewhere
between the beginning of the first invocation of
circuit_get_open_circ_or_launch and the second, we changed the state of
the conn to DESC_WAIT.
