o Minor bugfixes (circuit build timeout):
|
||
|
|
- Improve the accuracy of our circuit build timeout calculation for 60%,
|
||
|
|
70%, and 80% build rates for various guard choices. We now use a maximum
|
||
|
|
likelihood estimator for Pareto parameters of the circuit build time
|
||
|
|
distribution, instead of a "right-censored estimator". This causes
|
||
|
|
clients to ignore circuits that never finish building in their timeout
|
||
|
|
calculations. Previously, clients were counting such unfinished circuits
|
||
|
|
as having the highest possible build time value, when in reality these
|
||
|
|
circuits most likely just contain relays that are offline. We also now
|
||
|
|
wait a bit longer to let circuits complete for measurement purposes,
|
||
|
|
lower the minimum possible effective timeout from 1.5 seconds to 10ms,
|
||
|
|
and increase the resolution of the circuit build time histogram from
|
||
|
|
50ms bin widths to 10ms bin widths. Additionally, we alter our estimate
|
||
|
|
Xm by taking the maximum of the top 10 most common build time values
|
||
|
|
of the 10ms histogram, and compute Xm as the average of these.

Fixes bug 40168; bugfix on 0.2.2.14-alpha.
