Don't discard all circuits every MaxCircuitDirtiness, because the
user might legitimately have set that to a very lower number.
Also don't use up all of our idle circuits with testing circuits,
since that defeats the point of preemptive circuits.
Using CircuitBuildTimeout is prone to issues with SIGHUP, etc.
Also, shuffle the circuit build times array after loading it
in so that newer measurements don't replace chunks of
similarly timed measurements.
We were telling the controller about CHECKING_REACHABILITY and
REACHABILITY_FAILED status events whenever we launch a testing
circuit or notice that one has failed. Instead, only tell the
controller when we want to inform the user of overall success or
overall failure. Bugfix on 0.1.2.6-alpha. Fixes bug 1075. Reported
by SwissTorExit.
Previously, when we had the chosen_exit set but marked optional, and
we failed because we couldn't find an onion key for it, we'd just give
up on the circuit. But what we really want to do is try again, without
the forced exit node.
Spotted by rovv. Another case of bug 752. I think this might be
unreachable in our current code, but proposal 158 could change that.

cell back), avoid using that OR connection anymore, and also
tell all the one-hop directory requests waiting for it that they
should fail. Bugfix on 0.2.1.3-alpha.

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.

(The unfixed ones are being downgraded to regular XXXs mainly on the rationale that they don't seem to be exploding Tor, and they were apparently not showstoppers for 0.2.0.x-final.)

reachability testing circuits to do a bandwidth test -- if
we already have a connection to the middle hop of the testing
circuit, then it could establish the last hop by using the existing
connection. Bugfix on 0.1.2.2-alpha, exposed when we made testing
circuits no longer use entry guards in 0.2.1.3-alpha.

Initial conversion of uint32_t addr to tor_addr_t addr in connection_t and related types. Most of the Tor wire formats using these new types are in, but the code to generate and use it is not. This is a big patch. Let me know what it breaks for you.
svn:r16435
Move n_addr, n_port, and n_conn_id_digest fields of circuit_t into a separately allocated extend_info_t. Saves 22 bytes per connected circuit_t on 32-bit platforms, and makes me more comfortable with using tor_addr_t in place of uint32_t n_addr.

If you have more than one bridge but don't know their keys,
you would only learn a request for the descriptor of the first one
on your list. (Tor considered launching requests for the others, but
found that it already had a connection on the way for $0000...0000
so it didn't open another.)
If you have more than one bridge but don't know their keys, and the
connection to one of the bridges failed, you would cancel all
pending bridge connections. (After all, they all have the same
digest.)

Part of fix for bug 617: allow connection_ap_handshake_attach_circuit() to mark connections, to avoid double-mark warnings. Note that this is an incomplete refactoring.

Do the last part of arma's fix for bug 437: Track the origin of every addrmap, and use this info so we can remove all the trackhostexits-originated mappings for a given exit.

Refactor circuit_launch* functions to take a bitfield of flags rather than 4 separate nonconsecutive flags arguments. Also, note a possible but in circuit_find_to_cannibalize, which seems to be ignoring its purpose argument.

edge_connection_t: want_onehop if it must attach to a circuit with
only one hop (e.g. for the current tunnelled connections that use
begin_dir), and use_begindir if we mean to use a BEGIN_DIR relay
command to establish the stream rather than the normal BEGIN. Now
we can make anonymized begin_dir connections for (e.g.) more secure
hidden service posting and fetching.

Expire application streams in all cases if they've been around
longer than SocksTimeout. Right now there are some cases where the
stream will live forever, demanding a new circuit every 15 seconds.
Bugfix on 0.1.2.7-alpha; fixes bug 454; reported by lodger.

- Only listen to responses for "authority" fetches if we're configured
to use Bridges. Otherwise it's safe (and maybe smarter) to silently
discard them like we used to.
- React faster to download networkstatuses after the first bridge
descriptor arrives.
- Don't do dir fetches before we have any bridges, even when our
dirport is open.
svn:r10604
- demand options->Bridges and options->TunnelDirConns if
options->UseBridges is set.
- after directory fetches, accept descriptors that aren't referenced by
our networkstatuses, *if* they're for a configured bridge.
- delay directory fetching until we have at least one bridge descriptor.
- learn how to build a one-hop circuit when we have neither routerinfo
nor routerstatus for our destination.
- teach directory connections how to pick a bridge as the destination
directory when doing non-anonymous fetches.
- tolerate directory commands for which the dir_port is 0.
- remember descriptors when the requested_resource was "authority",
rather than just ignoring them.
- put bridges on our entry_guards list once we have a descriptor for them.
When UseBridges is set, only pick entry guards that are bridges. Else
vice versa.

Fix handling of resolves with very long or otherwise malformed addresses, and comment dns_resolve better, and stop making what should be a BUG warning into an assert(0). This fixes bug 427, which was introduced around 9900/9931/9932. Not a backport candidate: 0.1.2.x never had this bug.

authorities should set. This will let future authorities choose
not to serve V2 directory information.
Also, go through and revamp all the authdir_mode stuff so it tries
to do the right thing if you're an auth but not a V1 or V2 auth.

Make all LD_BUG log messsages get prefixed with "Bug: ". Remove manually-generated "Bug: "s from log-messages. (Apparently, we remembered to add them about 40% of the time.)

As a trivial optimization, remove a redundant call to router_have_minimum_dir_info. This might shave 2% on some systems by according to some profilers.

Removing the last DOCDOC comment hurt so much that I had to use Doxygen to identify undocumented macros and comments, and add 150 more DOCDOCs to point out where they were. Oops. Hey, kids! Fixing some of these could be your first Tor patch!

handshake to finish. Previously we would let them sit around for
days, if the connecting application didn't close them either.
Also take this opportunity to refactor a duplicate bit of circuituse.c.
And change the semantics of SocksTimeout slightly, but I think it'll
be ok.
svn:r9350
New socks command CONNECT_DIR. New config option TunnelDirConns that
builds a circ ending at the directory server and delivers a BEGIN_DIR
cell if it's running 0.1.2.2-alpha or later. We still need to make
one-hop circs when appropriate, while making other conns avoid them.
