Changes (by nickm):

 * status:  needs_review => needs_revision


Comment:

 Okay, another round of reviews. (Sorry about the delays):

   * We should prefer tor_malloc to malloc(); we should prefer
 tor_malloc_zero() to malloc()+bzero(). We should use tor_free(), not
 free().
   * This won't build with all our gcc warnings enabled. (It uses C99
 constructs by declaring variables in the middle of blocks.)
   * node_describe(rs) is a better choice than
 routerstatus_describe(node->rs) for describing nodes.
   * The tor_assert(hs_dir_node) thing makes me worry about race conditions
 where the node goes away after the circuit is launched.  Perhaps we can
 send events with node_describe(hs_dir_node) when hs_dir_node is non-null,
 and with the base 16 encoding if the ID when node_get_by_id() returns
 NULL?  That would be a fine thing to wrap into a "node_describe_by_id()"
 function.
   * Most of these new functions lack documentation.  See doc/HACKING for a
 documentation style.

 Anybody on the cc list want to offer to help dave2008 out with these
 changes? We've left him hanging for a while, they're fairly simple
 changes, and it would be cool to pick up some of our slack.
