commit 112d204fadab74426cc802e6d998a53f938a5248 Author: Robert Ransom <rransom.8774@gmail.com> Date: Sun May 29 08:03:41 2011 -0700 Set timestamp_dirty on HS circuits as circuit_expire_building requires Fixes part of #1297; bugfix on 48e0228f1e031a709c1deb149c7dfd187c3609cf, when circuit_expire_building was changed to assume that timestamp_dirty was set when a circuit changed purpose to _C_REND_READY.
