f1692ebefc when we do reachability testing and the tls cert at the other 
end disagrees with a descriptor we already have, be more useful

6fb27741ba Fix dirserv_get_networkstatus_v2's api: its function comments 
did not at all match its behavior, and I can't think of a case
when it should return anything other than 0.

This fix may allow getinfo dir/status/foo to work.

474c60b743 Cleanup on time-relaqted constants. New conventions: 
1) Surround all constants by (parens), whether we'll be using them
     in a denominator or not.
  2) Express all time periods as products (24*60*60), not as multiplied-out
     constants (86400).
  3) Comments like "(60*60) /* one hour */" are as pointless as comments
     like "c = a + b; /* set c to the sum of a and b */".  Remove them.
  4) All time periods should be #defined constants, not given inline.
  5) All time periods should have doxygen comments.
  6) All time periods, unless specified, are in seconds.  It's not necessary
     to say so.

To summarize, the old (lack of) style would allow:

  #define FOO_RETRY_INTERVAL 60*60 /* one hour (seconds) */
  next_try = now + 3600;

The new style is:

  /** How often do we reattempt foo? */
  #define FOO_RETRY_INTERVAL (60*60)

  next_try = now + RETRY_INTERVAL;

quickly if a server stops being reachable.

 2006-03-12 21:24:03 +00:00

1fc5eb329b We screwed up in anticipating how to add new dirservers: 
Old servers won't realize they're supposed to stay connected
to the new dirservers, so they'll expire connections to them,
but that means the dirservers will list them as unreachable.

So the fix is to stop requiring an open connection when deciding
if a server is reachable. This makes us slightly less accurate,
but at least it will work.

3) When an OR makes a second connection to you, allow it.
4) If we want to send a new create cell, but the best conn we've
   got is obsolete, and the router is 0.1.1.9-alpha-cvs or later, ask
   for a new conn instead.
