Changes in version 0.2.0.8-alpha - 2007-10-12
o Major features (router descriptor cache):
- Store routers in a file called cached-descriptors instead of in
cached-routers. Initialize cached-descriptors from cached-routers
if the old format is around. The new format allows us to store
annotations along with descriptors.
- Use annotations to record the time we received each descriptor.
- Use annotations to record the source for each descriptor.
- Use annotations to record the purpose of each descriptor.
- Bridge authorities now write bridge descriptors to disk, meaning
we can export them to other programs and begin distributing them
to blocked users.
o Major features (directory authorities):
- When an authority is missing votes or signatures, it now tries to fetch
them.
- When a v3 authority is missing votes or signatures, it now tries
to fetch them.
- Directory authorities track weighted fractional uptime as well as
weighted mean-time-between failures. WFU is suitable for deciding
whether a node is "usually up", while MTBF is suitable for deciding
whether a node is "likely to stay up." We need both, because "usually
up" is a good requirement for guards, while "likely to stay up" is
a good requirement for long-lived connections.

- All hosts now attempt to download and keep fresh v3 authority
certificates, and re-attempt after failures.

o Major bugfixes (performance):
- Fix really bad O(n^2) performance when parsing a long list of
routers: Instead of searching the entire list for an "extra-info "
string which usually wasn't there, once for every routerinfo
we read, just scan lines forward until we find one we like.
Bugfix on 0.2.0.1.
o Minor features (v3 authority system):
- Add more ways for tools to download the votes that lead to the current
consensus.
- Caches now download v3 network status documents as needed.
- Send a 503 when low on bandwidth and a vote, consensus, or certificate
is requested.

o Minor features (network statuses):
o Minor bugfixes (network statuses):
- Tweak the implementation of proposal 109 slightly: allow at most
two Tor servers on the same IP address, except if it's the location
of a directory authority, in which case allow five.

o Minor bugfixes (controller):
- When sending a status event to the controller telling it that an
OR address is readable, set the port correctly. (Previously we
were reporting the dir port.) Bugfix on 0.1.2.x.

gets rid of annoying "400 OK" log messages, which may have been masking
some deeper issue. Bugfix on 0.2.0.7-alpha.

o Minor bugfixes (Security):
- Never report that we've used more bandwidth than we're willing to
relay: it leaks how much non-relay traffic we're using. Resolves bug
516.

- Merge the extra fields in local_routerstatus_t back into
routerstatus_t: we used to need one routerstatus_t for each
authority's opinion, plus a local_routerstatus_t for the locally
computed consensus opinion. To save space, we put the locally
modified fields into local_routerstatus_t, and only the common stuff
into routerstatus_t. But once v3 directories are in use, clients and
caches will no longer need to hold authority opinions; thus, the
rationale for keeping the types separate is now gone.
- Make the code used to reschedule and reattempt downloads more uniform.
- Turn all 'Are we a directory?' logic into a call to dirserver_mode().
