Change the default values for collecting directory request statistics and
inlcuding them in extra-info descriptors to 1.
Don't break if we are configured to collect directory request or entry
statistics and don't have a GeoIP database. Instead, print out a notice
and skip initializing the affected statistics code.

Apparently autoheader throws a tantrum if you say 'AC_DEFINE([a],
[b])'. Instead you must say 'AC_DEFINE([a], [b], [description of
a])'. We were running into this in our replacement definitions for
FLEXIBLE_ARRAY_MEMBER, which were only getting built on autoconf
versions before 2.61 -- and this made us stop working with those
autoconf versinos.
Fixes bug 2430; bugfix on 0.2.3.1-alpha.
Right now we only force a new descriptor upload every 18 hours.
This can make servers become unlisted if they upload a descriptor at
time T which the authorities reject as being "too similar" to one
they uploaded before. Nothing will actually make the server upload a
new descriptor later on, until another 18 hours have passed.
This patch changes the upload behavior so that the 18 hour interval
applies only when we're listed in a live consensus with a descriptor
published within the last 18 hours. Otherwise--if we're not listed
in the live consensus, or if we're listed with a publication time
over 18 hours in the past--we upload a new descriptor every 90
minutes.
This is an attempted bugfix for #3327. If we merge it, it should
obsolete #535.
For some reason, autoconf doesn't by default have an "AC_PROG_AR" for
this -- possibly it's assumed that any "ar" you have will work
everyplace.
Fixes bug 3909; found by sid77.
This fixes a build issue first present in fdbdb4dc15, but the bug
(of not using a correct ar) has been in every Tor version ever: it
just didn't matter until then.
Add a "default" state which we use until we've decided whether we're
live or hibernating. This allows us to properly track whether we're
resuming a hibernation period or not. Fixes bug 2003.
For bufferevents, we had all of connection_buckets_decrement() stubbed
out. But that's not actually right! The rephist_* parts were
essential for, inter alia, recording our own bandwidth. This patch
splits out the rephist parts of connection_buckets_decrement() into their
own function, and makes the bufferevent code call that new function.
Fixes bug 3803, and probably 3824 and 3826 too. Bugfix on 0.2.3.1-alpha.
Previously, if you were set up to use microdescriptors, and you
weren't a cache, you'd never fetch router descriptors (except for
bridges). Now FetchUselessDescriptors causes descriptors and
mirodescs to get cached. Also, FetchUselessDescriptors changes the
behavior of "UseMicrodescriptors auto" to be off, since there's no
point in saying "UseMicrodescriptors 1" when you have full descriptors
too.
Fix for bug 3851; bugfix on 0.2.3.1-alpha.
Because tunneled connections are implemented with buffervent_pair,
writing to them can cause an immediate flush. This means that
added to them and then checking to see whether their outbuf is
empty is _not_ an adequate way to see whether you added anything.
This caused a problem in directory server connections, since they
would try spooling a little more data out, and then close the
connection if there was no queued data to send.
This fix should improve matters; it only closes the connection if
there is no more data to spool, and all of the spooling callbacks
are supposed to put the dirconn into dir_spool_none on completion.
This is bug 3814; Sebastian found it; bugfix on 0.2.3.1-alpha.
When we're doing filtering ssl bufferevents, we want the rate-limits
to apply to the lowest level of the bufferevent stack, so that we're
actually limiting bytes sent on the network. Otherwise, we'll read
from the network aggressively, and only limit stuff as we process it.
Also remove a few other related warnings that could occur during the ssl
handshake. We do this because the relay operator can't do anything about
them, and they aren't their fault.
Starting with Lion, Apple decided to deprecate the system openssl. We
can start requiring users to install their own openssl once OS X doesn't
ship with it anymore.
Right now, we append statistics to files in the stats/ directory for
half of the statistics, whereas we overwrite these files for the other
half. In particular, we append buffer, dirreq, and entry stats and
overwrite exit, connection, and bridge stats.
Appending to files was useful when we didn't include stats in extra-info
descriptors, because otherwise we'd have to copy them away to prevent
Tor from overwriting them.
But now that we include statistics in extra-info descriptors, it makes
no sense to keep the old statistics forever. We should change the
behavior to overwriting instead of appending for all statistics.
Implements #2930.
We'll still need to tweak it so that it looks for includes and
libraries somewhere more sensible than "where we happened to find
them on Erinn's system"; so that tests and tools get built too;
so that it's a bit documented; and so that we actually try running
the output.
Work done with Erinn Clark.
