Forward-port: I had apparently broken OSX and Freebsd by not initializing threading before we initialize the logging system. This patch should do so, and fix bug 671.

Make dumpstats() log the size and fullness of openssl-internal buffers, so I can test my hypothesis that many of them are empty, and my alternative hypothesis that many of them are mostly empty, against the null hypothesis that we really need to be burning 32K per open OR connection on this.
svn:r14350
New --hush command-line option similar to --quiet. While --quiet disables all
logging to the console on startup, --hush limits the output to messages of
warning and error severity.
svn:r14222
Only log a notice that dmalloc has been set up if it fails. Actually, since we have not added a temp log yet, I am not sure this ever does anything.
svn:r14216
example, when answering a directory request), reset the
time-to-give-up timeout every time we manage to write something
on the socket. Bugfix on 0.1.2.x.

Answer one xxx020 item; move 7 other ones to a new "XXX020rc" category: they should get fixed before we cut a release candidate. arma: please review these to see whether you have fixes/answers for any. Please check out the other 14 XXX020s to see if any look critical for the release candidate.

As planned, rename networkstatus_vote_t to networkstatus_t, now that v3 networkstatuses are working and standard and v2 networkstatuses are obsolete.
svn:r13383
Periodically check whether we have an expired consensus networkstatus. If we do, and we think we have enough directory info, then call router_dir_info_changed(). Fixes bug 401. This bug was deferred from 0.1.2.x, but fixing it there is nontrivial.
svn:r13342
Fix bug 575: protect the list of logs with a mutex. I couldn't find any appreciable change in logging performance on osx, but ymmv. You can undef USE_LOG_MUTEX to see if stuff gets faster for you.
svn:r13019
Here, have some terribly clever new buffer code. It uses a mbuf-like strategy rather than a ring buffer strategy, so it should require far far less extra memory to hold any given amount of data. Also, it avoids access patterns like x=malloc(1024);x=realloc(x,1048576);x=realloc(x,1024);append_to_freelist(x) that might have been contributing to memory fragmentation. I've tested it out a little on peacetime, and it seems to work so far. If you want to benchmark it for speed, make sure to remove the #define PARANOIA; #define NOINLINE macros at the head of the module.
svn:r12983
on but your ORPort is off.
Add a new config option BridgeRelay that specifies you want to
be a bridge relay. Right now the only difference is that it makes
you answer begin_dir requests, and it makes you cache dir info,
even if your DirPort isn't on.
Refactor directory_caches_dir_info() into some more functions.
svn:r12668
enough directory information. This was causing us to always pick
two new guards on startup (bugfix on 0.2.0.9-alpha), and it was
causing us to discard all our guards on startup if we hadn't been
running for a few weeks (bugfix on 0.1.2.x). Fixes bug 448.
svn:r12570
Keep track, for each OR connection, of the last time we added a non-padding cell to its outbuf. Use this timestamp, not "lastwritten" to tell if it is time to close a circuitless connection. (We can'tuse lastwritten, since lastwritten is updated when ever the connection flushes anything, and by that point we can no longer tell what is a padding cell and what is not.)
svn:r12437
Keep circuitless TLS connections open for 1.5 x MaxCircuitDirtiness: this ensures that we don't thrash closing and repoening connections to our guards.
svn:r12218
When a networkstatus consensus download fails, do not wait 60 seconds to decide whether to retry. (Also, log the time at which we'll try to replace the current networkstatus.)
svn:r12005
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
when we find our DirPort to be reachable but won't actually publish
it. Extra descriptors without any real changes are dropped by the
authorities, and can screw up our "publish every 18 hours" schedule.
svn:r11915
Refactor out about a third of routerlist.c into a new networkstatus.c. I\m not sure that I got everything that needed to move, but so far so good.
svn:r11791
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.
svn:r11761
Clean up MTBF storage code. Do not count times that we have been down toward the current run. Handle backward timewarps correctly. Store MTBF data on exit in addition to periodically.
svn:r11225
Glibc (and maybe others) define a mallinfo() that can be used to see how the platform malloc is acting inside. When we have it, dump its output on dumpmemusage().
svn:r10996
More directory voting code. Now, if everything works, and I haven't forgotten anything, it is possible to set up some v3 authorities and start voting. Of course, I have probably forgotten something, and there are probably bugs in there somewhere too.
svn:r10976
Maintain a detached-signatures document along with pending consensus document. Add a dirvote_free_all() to clean up static vars in dirvote.c
svn:r10945
Sun CC likes to give warnings for the do { } while(0) construction for making statement-like macros. Define STMT_BEGIN/STMT_END macros that do the right thing, and use them everywhere.

- 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.
svn:r10571
Initial version of patch from Karsten Loesing: Add an HSAuthorityRecordStats option to track statistics of overall hidden service usage without logging information that would be useful to an attacker.
svn:r10067
Initial version of code to stop using socket pairs for linked connections. Superficially, it seems to work, but it probably needs a lot more testing and attention.
svn:r9995
Track the number of connection_t separately from the number of open sockets. It is already possible to have connections that do not count: resolving conns, for one. Once we move from socketpairs to linked conns, and once we do dns proxying, there will be lots of such connections.
svn:r9994
Add code to shrink the cell memory pool by discarding empty chunks that have been empty for the last 60 seconds. Also, instead of having test.c duplicate declarations for exposed functions, put them inside #ifdef foo_PRIVATE blocks in the headers. This prevents bugs where test.c gets out of sync.
svn:r9944
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.)
svn:r9733
Remove some XXX012s: leave a check in connection_or_set_identity_digest it costs basically nothing to do on average. Forget about reinstating the user check on NT Service creation. Note that a notice message in main.c ("Is something wrong with your network connection?") is really useless.
svn:r9721
nt_service_is_stopping should not load the NT service library calls: if they are not loaded, we cannot possibly be a service trying to shut own. Bug found by "norvid" on or-talk. Also, rename function to something slightly less error-prone.
svn:r9720
Do not try to load advapi32.dll except when the user asks us to do something with NT services. When we _do_ try, always treat failure to load service functions as an exit-worthy error. Needs testing. (Fixes bug 389)
svn:r9571
(Hopefully) final changes for 0.1.2.7-alpha: disable checking for whether the user account in question exists on --service install, since that seems to make windows go boom. We can figure out why later. Also, let the admin specify a password for the target user.
svn:r9506
Remove a now-bogus assert() from nt_service_command_line(), and change option handling. (Now that we no longer force a -f, it is possible to have no command-line options for Tor-as-service.)
svn:r9503
The --service install code can no longer default to adding an -f option for the appdata directory of the current user, since the target user probably will not be able to read it. Instead, warn the user if no explicit torrc filename is given.
svn:r9502
More win32 account flumdummery: when LocalService exists, you can't detect it via LookupAccountName. The only good test is to see whether we're on win2k or earlier.
Apparently, somebody wouldn't know where to draw the line between implementation and interface if you gave them tracing paper and a copy of Stevens.
