When a directory authority is using a bandwidth file to obtain the
bandwidth values that will be included in the next vote, serve this
bandwidth file at /tor/status-vote/next/bandwidth.z.
It differs from the rest of the rephist code in that it's actually
necessary for Tor to operate, so it should probably go somewhere
else. I'm not sure where yet, so I'll leave it in the same
directory, but give it its own file.
The main.c code is responsible for initialization and shutdown;
the mainloop.c code is responsible for running the main loop of Tor.
Splitting the "generic event loop" part of mainloop.c from the
event-loop-specific part is not done as part of this patch.
In dirauth:
* bwauth.c reads and uses bandwidth files
* guardfraction.c reads and uses the guardfraction file
* reachability.c tests relay reachability
* recommend_pkg.c handles the recommended-packages lines.
* recv_descs.c handles fingerprint files and processing incoming
routerinfos that relays upload to us
* voteflag.c computes flag thresholds and sets those thresholds on
routerstatuses when computing votes
In control:
* fmt_serverstatus.c generates the ancient "v1 server status"
format that controllers expect.
In nodelist:
* routerstatus_fmt.c formats routerstatus entries for a consensus,
a vote, or for the controller.
There are now separate modules for:
* the list of router descriptors
* the list of authorities and fallbacks
* managing authority certificates
* selecting random nodes
Existing cached directory information can cause misleadingly high
bootstrap percentages. To improve user experience, defer reporting of
directory information progress until at least one connection has
succeeded to a relay or bridge.
Closes ticket 27169.
If bandwidth file terminator is found, set end of headers flag
and do not store the line.
If it is not, parse a relay line and check whether it is a header
line.
* add bwlist_headers argument to dirserv_read_measured_bandwidth
in order to store all the headers found when parsing the file
* add bwlist_headers to networkstatus_t in order to store the
the headers found by the previous function
* include the bandwidth headers as string in vote documents
* add test to check that dirserv_read_measured_bandwidth generates
the bwlist_headers
