Make connection_array into a smartlist.

Enable (and cope with) more GCC 4.2 warnings.

Refactor a bunch of functions that take edge_connection_t not to also take a crypt_path_t; the cpath is implicit.

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.)

Try to compile with fewer warnings on irix64's MIPSpro compiler /
environment, which apparently believes that:
- off_t can be bigger than size_t.
- only mean kids assign things they do not subsequently inspect.
I don't try to fix the "error" that makes it say:
cc-3970 cc: WARNING File = main.c, Line = 1277
conversion from pointer to same-sized integral type (potential portability
problem)
uintptr_t sig = (uintptr_t)arg;
Because really, what can you do about a compiler that claims to be c99
but doesn't understand that void* x = NULL; uintptr_t y = (uintptr_t) x;
is safe?

Dump breakdown of PK operations when we get a USR2 signal. This should help us figure out of we are doing some of them for stupid reasons.

Apply patch from Mike Perry: add more reasons for circuit destroys. (Slightly tweaked to avoid allocating a number for an "internal" reason.)

Patch from Mike Perry: add a REASON field to closed and failed circ events.

remove an assert that can never be false (an array in a non-null struct cannot be null).

Refactor connection_t into edge, or, dir, control, and base subtypes. This might save some RAM on busy exit servers, but really matters most in terms of correctness.
svn:r6906
|
|
No circuit can be both an intro point and a rend point, so we can merge both the cookie and the pk digest into one "rend_token" field for or circuits. This saves another 20 bytes per or circuit.
svn:r6904
|
|
Move rend_query to origin_circuit_t where it belongs; save another 17 bytes per OR circuit.
svn:r6903
|
|
circuit_t into origin_circuit_t and or_circuit_t. I fixed some
segaults; there may be more. We still need to move more rendezvous
stuff into subtypes.
This is a trial run for splitting up connection_t; if the approach is
insane, please say so soon so we can do something smarter.
Also, this discards the old HALF_OPEN code, which nobody seems to
want.

we have to explicitly "use" unuseds, but it can catch bugs. (It caught two coding mistakes so far.)

FetchServerDescriptors and FetchHidServDescriptors for whether
to fetch server info and hidserv info or let the controller do it,
and also PublishServerDescriptor and PublishHidServDescriptors.
Add AllDirActionsPrivate undocumented option -- if you set it, you'll
need the controller to bootstrap you enough to build your first circuits.

warn when we'recalling a non-named server by its nickname;
don't warn twice about the same name.
Fix a bug in routers_update_status_from_networkstatus that made nearly
all clients never update routerinfo_t.is_named.
Try to list MyFamily elements by key, not by nickname.
Only warn about names that we generated ourself, or got from the local
user.
On TLS handshake, only check the other router's nickname against its
expected nickname if is_named is set.

- Add a new extend_info_t datatype to hold information needed to
extend a circuit (addr,port,keyid,onion_key). Use it in cpath and
build_state. Make appropriate functions take or return it instead of
routerinfo_t or keyid.
- #if 0 needless check in circuit_get_by_edge_conn; if nobody triggers this
error in 0.1.0.10, nobody will trigger it.
- Implement new hidden service descriptor format, which contains "extend
info" for introduction points, along with protocol version list.
- Parse new format.
- Generate new format
- Cache old and new formats alongside each other.
- Directories serve "old" format if asked in old way, "newest available"
format if asked in new way.
- Use new format to find introduction points if possible; otherwise fall
back. Keep nickname lists and extendinfo lists in sync.
- Tests for new format.
- Implement new "v2" INTRODUCE cell format.
- Accept new format
- Use new format if we have a versioned service descriptor that says the
server accepts the new format.
- Add documentation for functions and data types.

more likely to fail on the first attempt, yet they work fine
on the second. so now give them extra time for the first try.

Also refactor circuit building so we plan the whole path ahead
of time.

until none are left, then we try to refetch the descriptor. If it's
the same one we had before, then close streams right then. Whenever
a new stream arrives, even if it's right after, optimistically try
refetching the descriptor, just in case.

a general circ, and called rend_client_rendcirc_has_opened(), which
called connection_ap_attach_pending(), which was needing a rendezvous
circ, so it cannibalized a general circuit, and called ...
svn:r3370

to the exit policy of the last hop. Intro and rendezvous circs must
be internal circs, to avoid leaking information. Resolve and connect
streams can use internal circs if they want.
New circuit pooling algorithm: make sure to have enough circs around
to satisfy any predicted ports, and also make sure to have 2 internal
circs around if we've required internal circs lately (with high uptime
if we've seen that lately).
Split NewCircuitPeriod config option into NewCircuitPeriod (30 secs),
which describes how often we retry making new circuits if current ones
are dirty, and MaxCircuitDirtiness (10 mins), which describes how long
we're willing to make use of an already-dirty circuit.
Once rendezvous circuits are established, keep using the same circuit as
long as you attach a new stream to it at least every 10 minutes. (So web
browsing doesn't require you to build new rend circs every 30 seconds.)
Cannibalize GENERAL circs to be C_REND, C_INTRO, S_INTRO, and S_REND
circ as necessary, if there are any completed ones lying around when
we try to launch one.
Re-instate the ifdef's to use version-0 style introduce cells, since
there was yet another bug in handling version-1 style. We'll try switching
over again after 0.0.9 is obsolete.
Bugfix: when choosing an exit node for a new non-internal circ, don't take
into account whether it'll be useful for any pending x.onion addresses --
it won't.
Bugfix: we weren't actually publishing the hidden service descriptor when
it became dirty. So we only published it every 20 minutes or so, which
means when you first start your Tor, the hidden service will seem broken.
