Nick Mathewson	c256f2c3a1	Make comment more sensible. Still uncertain about when to call rend_services_init, though. ... svn:r1580	2004-04-09 17:54:20 +00:00
Nick Mathewson	facb5d4221	Reload rendezvous service keys on sighup; otherwise, we wind up with a ... bunch of half-initialized services. This should solve half of weasel's current bug. The crash is the other half. (arma: should we also call rend_services_init on hup?) svn:r1578	2004-04-09 17:48:09 +00:00
Roger Dingledine	4011906b6b	get more serious about hunting The Bug ... (it has been haunting us since the days of 0.0.2preX) svn:r1576	2004-04-09 09:39:42 +00:00

Roger Dingledine	4a9587a486	we were uploading our server descriptor to each the dirservers ... when we boot, and then also on the first iteration of the main loop svn:r1520	2004-04-07 19:30:22 +00:00
Roger Dingledine	7793078dff	alice can now look up bob's service descriptor, ... choose an intro point, connect to it, choose a rend point, connect to it and establish a cookie, get an ack from the rendezvous point, and know when both circs are ready for her. APConns don't use conn->purpose anymore don't initiate a renddesc lookup if one is already in progress also fix a buffer overflow in nickname parsing (only exploitable by the operator though) svn:r1471	2004-04-05 00:47:48 +00:00

Roger Dingledine	d13857a3f0	put in hooks for alice and bob logic when circuits finish/fail ... let you specify the purpose of circuits you launch bugfix: we used to be declaring the first successful circuit too early -- when the first hop finished. now we're more accurate. svn:r1421	2004-04-01 01:57:22 +00:00

Roger Dingledine	a0b0d16981	Add an ap_bridge function to do a socketpair and skip socks. ... This allows us to do a directory connection *through* tor just as if we're doing it as an application. Make ap_conns tolerate it when the application sends stuff before The socks handshake is done (it just buffers it). Tell directory_initiate_command the length of the payload (because it might include nuls). Add a directory_has_arrived function to, for example, start building the rendezvous service descriptor. svn:r1412	2004-03-31 22:02:13 +00:00

Roger Dingledine	2d3ac08633	Refactor directory servers ... * read all the time (before we would ignore eof sometimes, oops) * we can handle different urls now * send back 404 for an un-handled url * commands initiated by the client can handle payloads now * introduce conn->purpose to avoid exponential state-space explosion svn:r1400	2004-03-30 22:57:49 +00:00

Nick Mathewson	0e6084d751	Remove descriptors that are older than 24 hours from the directory. Use strlcat instead of strncat to generate directories. ... svn:r1361	2004-03-29 19:28:16 +00:00

Roger Dingledine	47b40de0aa	only build circuits after we've fetched the directory ... this resolves a subtle bug where tor clients were preferentially using the directory servers, since when they start building circuits they know only about the directory servers on the other hand, it now takes longer after startup before there's a working circuit. so it goes. svn:r1350	2004-03-27 00:15:09 +00:00
Nick Mathewson	b7c2b18bd6	Add a RunTesting option to try to learn link state by creating test circuits, even when SocksPort is off. ... svn:r1327	2004-03-21 03:03:10 +00:00

Nick Mathewson	2ba2f02181	Integrate the new "rephist" [rep(utation) hist(ory)] module to trace ... successful/failed connections, successful/failed extends, and connection uptimes. It's still not done: more tests are needed, and not everything calls connection/circuit_mark_for_close properly. This skews the results. Also, there needs to be a 'testing' mode for non-OP ORs, where they periodically build circuits just to test whether extends work. svn:r1313	2004-03-20 04:59:29 +00:00
Roger Dingledine	208625ae31	clean up some presentation and comments ... svn:r1294	2004-03-18 19:22:56 +00:00

Roger Dingledine	10cee8b7f7	fix a rare race condition: when we send a cell and then ... mark an OR connection expired, we might close it before finishing a flush if the other side isn't reading. svn:r1240	2004-03-06 06:05:00 +00:00

Roger Dingledine	419a672222	holding until flush was borked ... we were never writing anything when hold_open_until_flushed was set, since conn_write returns early if marked_for_conn is set. seems a bit better now. svn:r1214	2004-03-03 08:46:18 +00:00

Roger Dingledine	611f117ce1	patches/answers to nick's commit ... svn:r1146	2004-02-27 23:23:33 +00:00
Nick Mathewson	c5bbb571d2	Refactor mark_for_close, connection_edge_end and friends. Now, everybody ... who wants to shut down a connection calls connection_mark_for_close instead of setting marked_for_close to 1. This automatically removes the connection from the DNS cache if needed, sends a RELAY END cell if appropriate, and can be changed to do whatever else is needed. Still to do: - The same for circuits, maybe. - Add some kind of hold_connection_open_until_flushed flag, maybe. - Change stuff that closes connections with return -1 to use mark_for_close, maybe. svn:r1145	2004-02-27 22:00:26 +00:00

Otherwise we expect connections to always already be up. bugfix: when choosing path length, pay attention to whether the directory says a router is down. bugfix: when picking good exit, skip routers which are known to be down (more work needs to be done on this one) svn:r838	2003-11-18 09:53:03 +00:00
