This is mostly a conversion from this pattern:
log("... %s:%d ...", fmt_and_decorate_addr(&addr), port);
to this:
log("... %s ...", fmt_addrport(&addr, port));
The output is the same in all cases.
Generate and store all supported microdescriptor formats. Generate
votes with one "m" line for each format. Only "m" lines with version
info matching chosen consensus method will be voted upon.
An optimisation would be to combine "m" lines with identical hashes,
i.e. instead of "m 1,2,3 H1" and "m 4,5 H1", say "m 1,2,3,4,5 H1".
Define new new consensus method 14 adding "a" lines to vote and
consensus documents.
From proposal 186:
As with other data in the vote derived from the descriptor, the
consensus will include whichever set of "a" lines are given by the
most authorities who voted for the descriptor digest that will be
used for the router.
This patch implements this.
The spec requires that every router in a microdesc consensus have an
m line; we weren't obeying that spec.
This creates a new consensus method (13) to allow voting to continue
to work right. Partial fix for bug 6404; fix on 0.2.2.6-alpha.
The SMARTLIST_FOREACH macro is more convenient than BEGIN/END when
you have a nice short loop body, but using it for long bodies makes
your preprocessor tell the compiler that all the code is on the same
line. That causes grief, since compiler warnings and debugger lines
will all refer to that one line.
So, here's a new style rule: SMARTLIST_FOREACH blocks need to be
short.
Also, try to resolve some doxygen issues. First, define a magic
"This is doxygen!" macro so that we take the correct branch in
various #if/#else/#endifs in order to get the right documentation.
Second, add in a few grouping @{ and @} entries in order to get some
variables and fields to get grouped together.
If the authorities agreed on a sufficiently bad bwweightscale value
(<=0 or == INT32_MAX), the bandwidth algorithm could make the voters
assert while computing the consensus.
Fix for bug5786; bugfix on 0.2.2.17-alpha
These were found by looking for tor_snprintf() instances that were
followed closely by tor_strdup(), though I probably converted some
other snprintfs as well.
(To ensure correctness, in every case, make sure that the temporary
variable is deleted, renamed, or lowered in scope, so we can't have
any bugs related to accidentally relying on the no-longer-filled
variable.)
This lets us make a lot of other stuff const, allows the compiler to
generate (slightly) better code, and will make me get slightly fewer
patches from folks who stick mutable stuff into or_options_t.
const: because not every input is an output!
Most instances were dead code; for those, I removed the assignments.
Some were pieces of info we don't currently plan to use, but which
we might in the future. For those, I added an explicit cast-to-void
to indicate that we know that the thing's unused. Finally, one was
a case where we were testing the wrong variable in a unit test.
That one I fixed.
This resolves bug 3208.

Here I looked at the results of the automated conversion and cleaned
them up as follows:
If there was a tor_memcmp or tor_memeq that was in fact "safe"[*] I
changed it to a fast_memcmp or fast_memeq.
Otherwise if there was a tor_memcmp that could turn into a
tor_memneq or tor_memeq, I converted it.
This wants close attention.
[*] I'm erring on the side of caution here, and leaving some things
as tor_memcmp that could in my opinion use the data-dependent
fast_memcmp variant.
The calculation of when to send the logmessage was correct, but we
didn't give the correct number of relays required: We want more than
half of all authorities we know about. Fixes bug 2663.
This means that "if (E<G) {abc} else if (E>=G) {def}" can be replaced with
"if (E<G) {abc} else {def}"
Doing the second test explicitly made my mingw gcc nervous that we might
never be initializing casename.
For my 64-bit Linux system running with GCC 4.4.3-fc12-whatever, you
can't do 'printf("%lld", (int64_t)x);' Instead you need to tell the
compiler 'printf("%lld", (long long int)x);' or else it doesn't
believe the types match. This is why we added U64_PRINTF_ARG; it
looks like we needed an I64_PRINTF_ARG too.
Some *_free functions threw asserts when passed NULL. Now all of them
accept NULL as input and perform no action when called that way.
This gains us consistence for our free functions, and allows some
code simplifications where an explicit null check is no longer necessary.
If all authorities restart at once right before a consensus vote, nobody
will vote about "Running", and clients will get a consensus with no usable
relays. Instead, authorities refuse to build a consensus if this happens.
This patch introduces a new type called document_signature_t to represent the
signature of a consensus document. Now, each consensus document can have up
to one document signature per voter per digest algorithm. Also, each
detached-signatures document can have up to one signature per <voter,
algorithm, flavor>.
This code adds a new field to vote on: "params". It consists of a list of
sorted key=int pairs. The output is computed as the median of all the
integers for any key on which anybody voted.
Improved with input from Roger.
The subversion $Id$ fields made every commit force a rebuild of
whatever file got committed. They were not actually useful for
telling the version of Tor files in the wild.

Refactor the is_vote field of networkstatus_t to add a third possibility ("opinion") in addition to vote and opinion. First part of implementing proposal 147.
svn:r16166
Do not allocate excess space for named_flag and unnamed_flag in dirvote.c. Fixes bug 662. Not a dangerous bug: sizeof(int*) is at least as big as sizeof(int) everywhere.
svn:r14391
add a flag to suppress overwriting the certificates file with new certificates, so we do not overwrite all certs when starting as an authority.
svn:r13630
As planned, rename networkstatus_vote_t to networkstatus_t, now that v3 networkstatuses are working and standard and v2 networkstatuses are obsolete.
svn:r13383
Change set_current_consensus interface to take a flags variable. Do not try to fetch certificates until after we have tried loading the fallback consensus. Should fix bug 583.

minutes, but writing the "valid-after" line in our vote based
on our configured V3AuthVotingInterval: so unless the intervals
matched up, we immediately rejected our own vote because it didn't
start at the voting interval that caused us to construct a vote.
This caused log entries like:

as 2007-10-23 05:30:00: consensus_set=0, interval=1800

Nick, you should look at this, as it's your design. :)
svn:r12129
Make authorities start accepting (and advertising their acceptance of) consensus method 2. If all goes well, we'll have a working Unnamed flag. Otherwise, we'll have a fun backtrace.
svn:r12113
When we decode to use consensus method 2 or later, compute Unnamed and Named more or less as described in 122. Don't actually use consensus method 2 yet, so we can be sure we didn't screw up v1..
svn:r12055
Implement v3 networkstatus client code. Remove v2 networkstatus client code, except as needed for caches to fetch and serve v2 networkstatues and the routers they list.
svn:r11957
Make discard_old_votes part of the consensus publishing process, so we conform to spec, and so we avoid a weird bugs where publishing sets the consensus, setting the consensus makes us reschedule, and rescheduling makes us delay vote-discarding.
svn:r11944
Fix a bunch of XXX020s: treat some 403s as INFO severity; remove some dead code; share the retry path for consensus routerdescs that are also listed in the v2 networkstatus; check even more aspects of votes when parsing them.
svn:r11871
Change dirvote_get_vote to take named flags rather than 3 boolean inputs. Fix a bug that was caused by the order of the boolean inputs in or.h not matching the order of boolean inputs in dirvote.c.
svn:r11812
Add a bunch of function documentation; clean up a little code; fix some XXXXs; tag the nonsensical EXTRAINFO_PURPOSE_GENERAL as nonsesnse; note another bit of "do not cache special routers" code to nuke.
