[tor-commits] [tor/master] Report only the first bootstrap failure from an orconn

[nickm@xxxxxxxxxxxxxx]

commit b0bbe6b2f1d8f0f2c83565f94d8a7dc5c5f72a91
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Thu Mar 27 15:58:43 2014 -0400

    Report only the first bootstrap failure from an orconn
    
    Otherwise, when we report "identity mismatch", we then later report
    DONE when the connection gets closed.
    
    Fixes bug 10431; bugfix on 0.2.1.1-alpha.
