| * | | Make the controller act more usefully when GETINFO fails•••Right now it says "552 internal error" because there's no way for
getinfo_helper_*() countries to specify an error message. This
patch changes the getinfo_helper_*() interface, and makes most of the
getinfo helpers give useful error messages in response to failures.
This should prevent recurrences of bug 1699, where a missing GeoIPFile
line in the torrc made GETINFO ip-to-county/* fail in a "not obvious
how to fix" way.

| * | | More gracefully handle corrupt state files.•••Save a backup if we get odd circuitbuildtimes and other state info.
In the case of circuit build times, we no longer assert, and reset our state.
| Mike Perry | 2010-07-06 |
| * | | Fix unittest failure in bug 1660.•••We now record large times as abandoned, to prevent a filter step from
happening and skewing our results.
Also, issue a warn for a rare case that can happen for funky values of Xm or
too many abandoned circuits. Can happen (very rarely) during unit tests, but
should not be possble during live operation, due to network liveness filters
and discard logic.

| * | | Fix bugs with assuming time_t can be implicitly cast to long•••Many friendly operating systems have 64-bit times, and it's not nice
to pass them to an %ld format.
It's also extremely not-nice to write a time to the log as an
integer. Most people think it's 2010 June 29 23:57 UTC+epsilon, not
1277855805+epsilon.

| | * | | Add CLOSE_MS and CLOSE_RATE keywords to buildtimeout event. | Mike Perry | 2010-06-15 |
| | * | | Split the circuit timeout and close codepaths.•••We need to record different statistics at point of timeout, vs the point
of forcible closing.
Also, give some better names to constants and state file variables
to indicate they are not dealing with timeouts, but abandoned circuits.

| | * | | Keep circuits open until the greater of 95th CDF percentile or 60s.•••This is done to provide better data to our right-censored Pareto model.

| | * | | Bug 1296: Add option+logic to disable CBT learning.•••There are now four ways that CBT can be disabled:
1. Network-wide, with the cbtdisabled consensus param.
2. Via config, with "LearnCircuitBuildTimeout 0"
3. Via config, with "AuthoritativeDirectory 1"
4. Via a state file write failure.

| | * | | Bug 1357: Store the suspended timeout value to resume.•••This prevents a spurious warning where we have a timeout just after
deciding our network came back online.
| Mike Perry | 2010-05-10 |
| | * | | Bug 1245: Ignore negative and large timeouts.•••This should prevent some asserts and storage of incorrect build times
for the cases where Tor is suspended during a circuit construction, or
just after completing a circuit. The idea is that if the circuit
build time is much greater than we would have cut it off at, we probably
had a suspend event along this codepath, and we should discard the
value.

| | * | | Bump timeout calculation message to notice when timeout changes. | Mike Perry | 2010-05-10 |
| | * | | Add consensus parameter for max synthetic quantile.•••In case we decide that the timeout rate is now too high due to our
change of the max synthetic quantile value, this consensus parameter
will allow us to restore it to the previous value.
| Mike Perry | 2010-05-10 |
| | * | | Add a TIMEOUT_RATE keyword to buildtimeout event. | Mike Perry | 2010-05-10 |
| | * | | Bug 1335: Implement filtering step to remove+prevent high timeouts.•••This is for the other issue we saw in Bug 1335. A large number of high
timeouts were causing the timeout calculation to slowly drift upwards,
especially in conditions of load. This fix repeatedly regenerates all of
our synthetic timeouts whenever the timeout changes, to try to prevent
drift.
It also lowers the timeout cap to help for some cases of Bug 1245, where
some timeout values were so large that we ended up allocating a ton of
scratch memory to count the histogram bins.
The downside is that lowering this cap is affecting our timeout rate.
Unfortunately, the buildtimeout quantile is now higher than the actual
completion rate by what appears to be about 7-10%, which probably
represents the skew in the distribution due to lowering this synthetic
cap.
| Mike Perry | 2010-05-10 |
| | * | | Bug 1335: Alter Xm calculation to be weighted avg of top N=3 modes.•••In my state files, I was seeing several peaks, probably due to different
guards having different latency. This change is meant to better capture
this behavior and generate more reasonable timeouts when it happens. It
is improving the timeout values for my collection of state files.

a reserved word.

| * | | Merge branch 'asprintf' | Nick Mathewson | 2010-04-02 |
| |\ \ |
|
| | * | | Add a tor_asprintf() function, and use it in a couple of places.•••asprintf() is a GNU extension that some BSDs have picked up: it does a printf
into a newly allocated chunk of RAM.
Our tor_asprintf() differs from standard asprintf() in that:
- Like our other malloc functions, it asserts on OOM.
- It works on windows.
- It always sets its return-field.
