* use a rbtree for replay detection, rather than linear search•••when we had lots of new onions coming in, we were using 40% of our time searching through the tracked_onions linked list. svn:r150 Roger Dingledine2002-12-31
* onions go on and off the network correctly now•••we're closer to an OS X port CVS: ---------------------------------------------------------------------- svn:r146 Roger Dingledine2002-12-03
* onions expire after a day, not an hour•••this was a major faq, because it would fail with an error only on the *server* side when the client-side time was wrong. the client would simply not work. svn:r145 Roger Dingledine2002-12-03
* two more rare race conditions•••svn:r143 Roger Dingledine2002-11-28
* create cells are now queued and processed only when idle•••we also queue data cells destined for a circuit that is pending, and process them once the circuit opens destroys reach into the queue and remove the pending onion, along with its collected data cells svn:r142 Roger Dingledine2002-11-27
* remove popt dependency, consolidate config stuff•••reformat parts of onion.c svn:r136 Roger Dingledine2002-11-23
* cleanup and a variety of bugfixes•••svn:r132 Roger Dingledine2002-10-02
* Add convenience functions to wrap create and init for symmetric ciphers; clea...•••svn:r131 Nick Mathewson2002-10-02
* cleanup•••prkey is only fetched when it's needed tor nodes who aren't dirservers now fetch directories and autoconnect to new nodes listed in the directory default role is a non-dirserver node svn:r120 Roger Dingledine2002-09-28
* laying the groundwork for dynamic router lists•••revamped the router reading section reference counting for crypto pk env's (so we can dup them) we now read and write pem pk keys from string rather than from FILE*, in anticipation of fetching directories over a socket (so now on startup we slurp in the whole file, then parse it as a string) fixed a bug in the proxy side, where you could get some circuits wedged if they showed up while the connection was being made svn:r110 Roger Dingledine2002-09-24
* synchronize to the version i've been giving people to test•••svn:r104 Roger Dingledine2002-09-19
* onion proxies now work (i think)•••svn:r96 Roger Dingledine2002-09-04
* clarifying the empty semicolon•••svn:r90 Roger Dingledine2002-09-03
* Port to MacOS X•••svn:r88 Nick Mathewson2002-09-03
* port is now kept in host order except in sin_port•••svn:r82 Roger Dingledine2002-08-24
* cleanup: don't use size_t when you mean int•••size_t is what you get back from sizeof(). no more, no less. svn:r80 Roger Dingledine2002-08-24
* changed path selection so it's actually random again•••svn:r78 Roger Dingledine2002-08-23
* cleaned up new_route()•••now it deals gracefully with too few connected routers (i think) svn:r77 Roger Dingledine2002-08-23
* Changed crypto calls to go through common/crypto.[hc] instead of calling Open...•••svn:r76 Matej Pjafjar2002-08-22
* only choose routers for the onion that are currently connected to us•••svn:r72 Roger Dingledine2002-07-22
* bugfix: create_onion now works with routelen>2•••svn:r66 Roger Dingledine2002-07-20
* Implemented router twins•••I modified new_route so we don't pick twins back-to-back in the path. I also had to patch my previous uses of connection_twin_get_by_addr_port() because they assumed that "addr" and "port" would be the same for a twin as for the original router. svn:r56 Roger Dingledine2002-07-18
* Implemented link padding and receiver token buckets•••Each socket reads at most 'bandwidth' bytes per second sustained, but can handle bursts of up to 10*bandwidth bytes. Cells are now sent out at evenly-spaced intervals, with padding sent out otherwise. Set Linkpadding=0 in the rc file to send cells as soon as they're available (and to never send padding cells). Added license/copyrights statements at the top of most files. router->min and router->max have been merged into a single 'bandwidth' value. We should make the routerinfo_t reflect this (want to do that, Mat?) As the bandwidth increases, and we want to stop sleeping more and more frequently to send a single cell, cpu usage goes up. At 128kB/s we're pretty much calling poll with a timeout of 1ms or even 0ms. The current code takes a timeout of 0-9ms and makes it 10ms. prepare_for_poll() handles everything that should have happened in the past, so as long as our buffers don't get too full in that 10ms, we're ok. Speaking of too full, if you run three servers at 100kB/s with -l debug, it spends too much time printing debugging messages to be able to keep up with the cells. The outbuf ultimately fills up and it kills that connection. If you run with -l err, it works fine up through 500kB/s and probably beyond. Down the road we'll want to teach it to recognize when an outbuf is getting full, and back off. svn:r50 Roger Dingledine2002-07-16
* Integrated onion proxy into or/•••The 'or' process can now be told (by the global_role variable) what roles this server should play -- connect to all ORs, listen for ORs, listen for OPs, listen for APs, or any combination. * everything in /src/op/ is now obsolete. * connection_ap.c now handles all interactions with application proxies * "port" is now or_port, op_port, ap_port. But routers are still always referenced (say, in conn_get_by_addr_port()) by addr / or_port. We should make routers.c actually read these new ports (currently I've kludged it so op_port = or_port+10, ap_port=or_port+20) * circuits currently know if they're at the beginning of the path because circ->cpath is set. They use this instead for crypts (both ways), if it's set. * I still obey the "send a 0 back to the AP when you're ready" protocol, but I think we should phase it out. I can simply not read from the AP socket until I'm ready. I need to do a lot of cleanup work here, but the code appears to work, so now's a good time for a checkin. svn:r22 Roger Dingledine2002-07-02
* Initial revision•••svn:r2 Roger Dingledine2002-06-26
