Don't cast uint64_t * to const uint64_t * explicitly. The cast is always
safe, so C does it for us. Doing the cast explitictly can hide bugs if
the input is secretly the wrong type.
Suggested by Nick.
As a bridge authority, before we create our networkstatus document, we
should compute the thresholds needed for the various status flags
assigned to each bridge based on the status of all other bridges. We
then add these thresholds to the networkstatus document for easy access.
Fixes for #1117 and #9859.
Also fix a bug where if the guard we choose first doesn't answer, we
would try the second guard, but once we connected to the second guard
we would abandon it and retry the first one, slowing down bootstrapping.
The fix in both cases is to treat all our initially chosen guards as
acceptable to use.
Fixes bug 9946.
We had updated our "do we have enough microdescs to begin building
circuits?" logic most recently in 0.2.4.10-alpha (see bug 5956), but we
left the bootstrap status event logic at "how far through getting 1/4
of them are we?"
Fixes bug 9958; bugfix on 0.2.2.36, which is where they diverged (see
bug 5343).
The old code had logic to use a shorter path length if we didn't
have enough nodes. But we don't support 2-node networks anwyay.
Fix for #9926. I'm not calling this a bugfix on any particular
version, since a 2-node network would fail to work for you for a lot
of other reasons too, and it's not clear to me when that began, or if
2-node networks would ever have worked.
By calling circuit_n_chan_done() unconditionally on close, we were
closing pending connections that might not have been pending quite for
the connection we were closing. Fix for bug 9880.
Thanks to skruffy for finding this and explaining it patiently until
we understood.
this was causing directory authorities to send a time of 0 on all
connections they generated themselves, which means everybody reachability
test caused a time skew warning in the log for that relay.
(i didn't just revert, because the changes file has been modified by
other later commits.)
