Mike Perry	b918cd8f04	Remove another overzealous assert. ... Pretimeouts may have build time data, just no timeout data.	2009-10-07 12:24:40 -07:00
Roger Dingledine	b4e0d09202	try to stem the 'sea of fail'	2009-10-01 05:35:24 -04:00
Roger Dingledine	9325b9269c	Ignore one-hop circuits for circuit timeout calc ... Don't count one-hop circuits when we're estimating how long it takes circuits to build on average. Otherwise we'll set our circuit build timeout lower than we should. Bugfix on 0.2.2.2-alpha.	2009-10-01 04:15:45 -04:00
Mike Perry	f7e6e852e8	Fix 1108: Handle corrupt or large build times state. ... 1108 was actually just a fencepost error in an assert, but making the state file handling code resilient is a good idea.	2009-09-29 14:07:04 -04:00
Sebastian Hahn	7f1f6984da	Fix memory leak ... Some memory could be lost in the error case of circuit_build_times_parse_state. Found by Coverity	2009-09-27 12:00:02 -04:00
Mike Perry	fd7454f9e3	Fix Bug 1103. ... Don't pass in a quantile that is too high during pretimeout calcualtion.	2009-09-21 20:01:20 -07:00
Mike Perry	134266b984	Change the condition on the nonlive timeout counting. ... Try to clarify things in the comment too.	2009-09-20 18:20:10 -07:00
Roger Dingledine	cf2afcd707	Fix typos and comments, plus two bugs ... A) We were considering a circuit had timed out in the special cases where we close rendezvous circuits because the final rendezvous circuit couldn't be built in time. B) We were looking at the wrong timestamp_created when considering a timeout.	2009-09-20 19:50:44 -04:00
Mike Perry	f39bedf250	Implement and document new network liveness algorithm. ... Based on irc discussion with arma.	2009-09-20 14:51:30 -07:00
Mike Perry	6700e528be	Fix some precision-related asserts in unit tests. ... Mostly by storing the timeout as milliseconds and not seconds internally.	2009-09-20 14:43:45 -07:00

Mike Perry	0352d43917	Move circuitbuildtimeout config check. ... We want it to be under our control so it doesn't mess up initialization. This is likely the cause for the bug the previous assert-adding commit (09a75ad) was trying to address.	2009-09-16 15:58:42 -07:00
Mike Perry	09a75ad316	Time for some debugging by asserts. ... Got a negative timeout value on startup. Need to narrow it down.	2009-09-16 15:55:51 -07:00

Mike Perry	63be2df84f	Fix issues found by arma in review.	2009-09-16 15:55:36 -07:00

Mike Perry	4b3bc714a3	Woops. Fix a couple memory leaks. ... Also change the max timeout quantile to 0.98, so we can avoid huge synthetic timeout values.	2009-09-16 15:54:37 -07:00
Karsten Loesing	b508e4748f	Remove trailing spaces. As if bytes were free... ... Also correct some typos.	2009-09-16 15:52:05 -07:00

Mike Perry	8210336182	More detail for some log msgs.	2009-09-16 15:52:04 -07:00
Mike Perry	6eba08e22f	Use our variable directly for timeout. ... Using CircuitBuildTimeout is prone to issues with SIGHUP, etc. Also, shuffle the circuit build times array after loading it in so that newer measurements don't replace chunks of similarly timed measurements.	2009-09-16 15:52:04 -07:00
Mike Perry	fca8446949	Fix a couple of assert bugs.	2009-09-16 15:52:03 -07:00
Mike Perry	c4e6b3eadb	Fix timeout edge case when we get enough samples. ... Also switch Xm calculation to mode, not min.	2009-09-16 15:52:03 -07:00
Mike Perry	95735e5478	Fix the math.h log() conflict. ... It was compiling, but causing segfaults. Also, adjust when the timer starts for new test circs and save state every 25 circuits.	2009-09-16 15:51:17 -07:00
Mike Perry	7ac9a66c8f	Recover from changing network connections. ... Also add code to keep creating circuits every minute until we hit our minimum threshhold.	2009-09-16 15:51:16 -07:00
Mike Perry	411b60325b	Factor out the pretimeout handling code. ... We need to also call it if we're going to calculate alpha after a normal circuit build.	2009-09-16 15:51:15 -07:00
Mike Perry	b52bce91fc	Write unit tests and fix issues they uncovered.	2009-09-16 15:51:10 -07:00

Mike Perry	7750bee21d	Clean up Fallon's partially complete GSoC project. ... The code actually isn't that bad. It's a shame she didn't finish. Using it as the base for this feature.	2009-09-16 15:48:51 -07:00
Nick Mathewson	ed7283d283	Merge commit 'origin/maint-0.2.1' ... Resolved conflicts in: src/or/circuitbuild.c	2009-09-15 19:37:26 -04:00
Sebastian Hahn	113ba0e727	make some bug 1090 warnings go away ... When we excluded some Exits, we were sometimes warning the user that we were going to use the node regardless. Many of those warnings were in fact bogus, because the relay in question was not used to connect to the outside world. Based on patch by Rotor, thanks!	2009-09-16 01:17:51 +02:00
Sebastian Hahn	5e01a86b42	some cleanups: ... documentation fix for get_uint64 remove extra "." from a log line fix a long line	2009-09-15 07:12:12 -04:00
Roger Dingledine	c43859c5c1	Read "circwindow=x" from the consensus and use it ... Tor now reads the "circwindow" parameter out of the consensus, and uses that value for its circuit package window rather than the default of 1000 cells. Begins the implementation of proposal 168.	2009-09-15 06:33:33 -04:00
Roger Dingledine	a225469ded	Merge branch 'maint-0.2.1'	2009-08-31 16:26:01 -04:00
Roger Dingledine	4c297f74f7	Only send reachability status events on overall success/failure ... We were telling the controller about CHECKING_REACHABILITY and REACHABILITY_FAILED status events whenever we launch a testing circuit or notice that one has failed. Instead, only tell the controller when we want to inform the user of overall success or overall failure. Bugfix on 0.1.2.6-alpha. Fixes bug 1075. Reported by SwissTorExit.	2009-08-31 16:14:41 -04:00
Nick Mathewson	77ffd6b2a7	Merge commit 'origin/maint-0.2.1'	2009-05-31 19:17:22 -04:00
Nick Mathewson	c4c7dcd453	Do not report a node as a "chosen exit" when it is not in fact an exit. ... Provide a useful warning when launch_circuit tries to make us use a node we don't want to use. Just give an info message when this is a normal and okay situation. Fix for logging issues in bug 984.	2009-05-31 19:15:36 -04:00
Nick Mathewson	cb18fc2190	Merge commit 'origin/maint-0.2.1'	2009-05-27 18:12:18 -04:00
Nick Mathewson	ec7e054668	Spell-check Tor.	2009-05-27 17:55:51 -04:00
Nick Mathewson	b998fed9b9	Remove support for events without the extended format or long names. ... Supporting the old formats made our code complex; running without them has been discouraged since 0.2.1.x.	2009-05-25 12:52:25 -04:00
