| | * | | 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.
| Mike Perry | 2010-06-15 |
| | * | | Fix initialization and reset issues with close_ms.•••Also clean up some log messages.
| Mike Perry | 2010-06-15 |
| | * | | 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.
We do this by simply marking them with a new purpose.

| | * | | 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 |
| | * | | 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.

| | * | | 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.

| * | | | Let bridge users use the non-primary address of a multi-homed bridge | Roger Dingledine | 2010-06-03 |
| * | | | Port Tor to work on Windows CE•••Most of the changes here are switches to use APIs available on Windows
CE. The most pervasive change is that Windows CE only provides the
wide-character ("FooW") variants of most of the windows function, and
doesn't support the older ASCII verions at all.
This patch will require use of the wcecompat library to get working
versions of the posix-style fd-based file IO functions.

| * | | Move the declaration of bandwidth_rate_rule_to_string•••It's natural for the definition of bandwidth_rule_t to be with the functions
that actually care about its values. Unfortunately, this means declaring
bandwidth_rate_rule_to_string() out of sequence. Someday we'll just rename
reasons.c to strings.c, and put it at the end of or.h, and this will all be
better.

| * | | Be more willing to use an unsuitable circuit for exit.•••Specifically, there are two cases: a) are we willing to start a new
circuit at a node not in your ExitNodes config option, and b) are we
willing to make use of a circuit that's already established but has an
unsuitable exit.
Now we discard all your circuits when you set ExitNodes, so the only
way you could end up with an exit circuit that ends at an unsuitable
place is if we explicitly ran out of exit nodes, StrictNodes was 0,
and we built this circuit to solve a stream that needs solving.
Fixes bug in dc322931, which would ignore the just-built circuit because
it has an unsuitable exit.
| Roger Dingledine | 2009-12-21 |
| * | | Make EntryNodes config option much more aggressive.•••Before it would prepend your requested entrynodes to your list of guard
nodes, but feel free to use others after that. Now it chooses only
from your EntryNodes if any of those are available, and only falls back
to others if a) they're all down and b) StrictNodes is not set.
Also, now we refresh your entry guards from EntryNode at each consensus
fetch (rather than just at startup and then they slowly rot as the
network changes).
The goal here is to make users less likely to set StrictNodes, since
it's doing closer to what they expect it should be doing.
| Roger Dingledine | 2009-12-21 |
| * | | Switch to a StrictNodes config option.•••This is step one of handling ExcludedNodes better. This first
step is just to make EntryNodes and ExitNodes do what they did
before.

| | * | | Change interface for configuring cell ewma algorithm.•••The rule is now: take the value from the CircuitPriorityHalflife
config option if it is set. If it zero, disable the cell_ewma
algorithm. If it is set, use it to calculate the scaling factor.
If it is not set, look for a CircPriorityHalflifeMsec parameter in the
consensus networkstatus. If *that* is zero, then disable the cell_ewma
algorithm; if it is set, use it to calculate the scaling factor.
If it is not set at all, disable the algorithm.
