| | | | | | | | | when building testing circs for orport testing, require high-bandwidth nodes, so fewer circs fail. complain about unreachable orport separately from unreachable dirport. svn:r3935

* Checkpoint in-progress fixes:Roger Dingledine2005-02-27
| | | | | | | | | | | | | Add 'testing' circuit purpose, for reachability testing. Notice when our IP changes, and reset stats. Try to pull down a directory via Tor to see if our DirPort is working. Try to extend a circuit back to us to see if our ORPort is working. Only publish a descriptor if they're both reachable. These mostly work, and I'd better get them in before I cause conflicts. svn:r3703

* fix another bug where general exit circs were looking at rendezvousRoger Dingledine2005-01-19
| | | | | | | | streams. consolidate the looking into one function so it doesn't happen again. svn:r3372
* remove some extra-verbose logsRoger Dingledine2005-01-17
| | | | svn:r3361
* Introduce a notion of 'internal' circs, which are chosen without regardRoger Dingledine2005-01-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 We'll try switching over again after 0.0.9 is obsolete.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. svn:r3360
* Annotate circuits w/ whether they aim to contain high uptime nodes and/orRoger Dingledine2005-01-12
| | | | | | | | | | | | | | | | | high capacity nodes. When building circuits, choose appropriate nodes. New config option LongLivedPorts to indicate application streams that will want high uptime circuits. When attaching a stream to a circuit, pay attention to its requirements. This means that every single node in an intro rend circuit, not just the last one, will have a minimum uptime. Boost the min uptime from an hour to 24 hours. svn:r3339
* When listing circuits that are pending on an opening OR connection,Roger Dingledine2004-12-17
| | | | | | | | if we're an OR we were listing circuits that *end* at us as being pending on every listener, dns/cpu worker, etc. Stop that. svn:r3171
* clean up logging,Roger Dingledine2004-12-13
| | | | | | | | | make it clearer which warns are bugs, make the control log event match its specification, point out a bug in how we deal with failure when renewing the tls context. svn:r3138
* I'm a bad person.Roger Dingledine2004-12-07
| | | | | | | | | Stop treating the uint16_t's as null-terminated strings, and stop looking at the byte after them to see if it's null, because sometimes you're not allowed to look there. svn:r3108

* New circuit building strategy: keep a list of ports that we've used in ↵Roger Dingledine2004-12-05
| | | | | | | | | | | | | | | | | | | | | | | | | the past 6 hours, and always try to have 2 circuits open or on the way that will handle each such port. (We can extend this to include addresses if exit policies shift to require that.) Seed us with port 80 so web browsers won't complain that Tor is "slow to start up". This was necessary because our old circuit building strategy just involved counting circuits, and as time went by we would build up a big pile of circuits that had peculiar exit policies (e.g. only exit to 9001-9100) which would take up space in the circuit pile but never get used. Fix router_compare_addr_to_addr_policy: it was not treating a port of * as always matching, so we were picking reject *:* nodes as exit nodes too. If you haven't used a clean circuit in an hour, throw it away, just to be on the safe side. This means after 6 hours a totally unused Tor client will have no circuits open. svn:r3078
* bugfix: When we were checking to see if an ap_conn should time outRoger Dingledine2004-12-04
| | | | | | | | | | | | | waiting for its connected cell, we were calculating time from when the ap_conn was created. So if it waited say 20 seconds before being attached, then we would immediately decide that the circuit had timed out. Also, make circuit_dump_by_conn() display actual circuit progress, including circuits that haven't been attached to the conn yet but hope to when it finishes connecting. svn:r3072
