[tor/master] Treat SW_SERVER_HELLO_B as another sign of an SSL handshake
by nickm＠torproject.org 11 Jun '12

commit e3243ad5f6a2c6acfd671e2cab22c4b6a4c21f47 Author: Nick Mathewson <nickm(a)torproject.org> Date: Tue May 15 11:13:49 2012 -0400 Treat SW_SERVER_HELLO_B as another sign of an SSL handshake We've been only treating SW_SERVER_HELLO_A as meaning that an SSL handshake was happening. But that's not right: if the initial attempt to write a ServerHello fails, we would get a callback in state SW_SERVER_HELLO_B instead. (That's "instead" and not "in addition": any failed attempt to write the hello will fail and cause the info callback not to get written.)
