This should improve the timeout calculation in some cases, and prevent extremely high timeout values. Bug 1335, bugfix on 0.2.2.2-alpha. - - Implement a filtering step to recompute synthetic build times every time - the timeout changes. Additionally, place a lower cap on synthetic build - times, and allow this cap to be controlled by the consensus. This should - also improve the build time calculations, and should eliminate a case - where Tor was allocating an excessive amount of temporary memory during - timeout calculation. Bugs 1335 and 1245, bugfix on 0.2.2.2-alpha. + - Alter calculation of Pareto distribution parameter 'Alpha' to use a + right censored distribution model. This allows us to remove the synthetic + timeout generation and instead calculate build timeouts using truncated + times.

This is done to provide better data + for the new Pareto model.

Bugfix on 0.2.2.2-alpha. o Minor features: - Add a TIMEOUT_RATE keyword to the BUILDTIMEOUT_SET control port event,
