* The old code should use circ failures..loggingMike Perry2011-12-05
| | | | | I think this was added because circ_fail_rate used to get set to 0 by a consensus param that we later changed.
* Always display per-class logs, even if the feature is disabled.Mike Perry2011-12-05
| | | | | I want to try to disable it and see if these become more even or not.
* Improve and demote some noisy loglines.Mike Perry2011-12-04
|
* Clean up the spec a tad.Mike Perry2011-12-03
|
* Allow us to cap feedback via consensus param.Mike Perry2011-12-03
| | | | Also demote a couple logs, and add a couple more.
* Make the pid target bw actually converge.Mike Perry2011-12-02
| | | | | This seems to only take a few seconds to do.. Expensive, but probably not prohibitively so?
* Be more merciful.Mike Perry2011-12-02
| | | | | We can just check to see if we've previously punished the node by inspecting the previous values directly. Forgot about that.
* Implement mercy, subject to consensus parameter.Mike Perry2011-12-02
| | | | | | If the param is set, we don't accumulate negative pid_error_sum for nodes with negative pid_error. Prevents us from punishing these nodes to 0 bw. The param only makes sense for descriptor-based feedback.
* Add a consensus param to raise the PID setpoint.Mike Perry2011-12-02
| | | | | Intuitively, it seems to make sense to exclude nodes with no chance of reaching the setpoint from consideration.
* Use FastFirstHopPK to get circ fail rates for Guards.Mike Perry2011-12-02
| | | | Otherwise we might not detect CPU overload conditions in them.
* Actually, we should be using min(circ_error,pid_error).Mike Perry2011-12-02
|
* Directly use the circ_error if it is negative.Mike Perry2011-12-01
|
* Fix variable shadow, and add some logs.Mike Perry2011-12-01
|
* Change how circuit failure is used.Mike Perry2011-12-01
| | | | Let's try computing a second error and take their sum.
* Implement per-class setpoints.Mike Perry2011-12-01
| | | | Governed by consensus param (off by default).
* Alter default param values.Mike Perry2011-12-01
| | | | | | These defaults should still be equivalent to Section 2 in the spec, but these values will keep the PID interim state from disappearing every time ides crashes and the consensus params disappear.
* Fix an exception that can happen with very large bandwidths.Mike Perry2011-12-01
| | | | | We have a cap+log warn below that we will hit in this case instead of crashing.
* Use desc bw if consensus bw is missing for some log linesMike Perry2011-11-20
|
* Add some notifications for #4359/#2286.Mike Perry2011-11-20
|
* Be consistent about Wgd application for Guard+Exit nodes.Mike Perry2011-11-20
| | | | Also correct log line.
* Display a total of previous consensus bw measured in INFO logs.Mike Perry2011-11-20
|
* Output git revision.Mike Perry2011-11-20

* Bug 2014: Provide url to backup bw server.Mike Perry2011-11-20

* Bug #4330: Have snakeinspector attach files if they existsoat-attachmentsMike Perry2011-11-19

* Forgot a spec paragraph..Mike Perry2011-11-17

* Merge branch 'pid_control-rebased'Mike Perry2011-11-17

| * Let's try turning FetchDirInfo*Early on by default.Mike Perry2011-11-17
| | | | | | | | Memory-only sqlite might make them more bearable.
| * Update spec to include consensus params.Mike Perry2011-11-17
| | | | | | | | | | These are still subject to change, especially in terms of defaults.
| * Allow desc bw to be used in feedback.Mike Perry2011-11-17
| | | | | | | | | | It may be equivalent to NS bw, since the NS bw functions as an accumulator.. We may want to set T_i_decay to 0 for this code.
| * Submodule.Mike Perry2011-11-17

| * Switch to memory-only sqlalchemy by default.Mike Perry2011-11-17

| * Add some comments about potential timeout issues.Mike Perry2011-11-17

| * Update scanner cutoffs and timeouts in config.Mike Perry2011-11-17

| * Update pythonpath to modern versions.Mike Perry2011-11-17

| * Prevent file size list from double-listing percentiles.Mike Perry2011-11-17
| | | | | | | | | | If two different file sizes serve one percentile, go with the smaller file size.
| * Differentiate measured and update timestamps.Mike Perry2011-11-17
| | | | | | | | | | | | | | This helps us to track Guard node feedback/non-feedback better. We may also end up using this to determine T_d and possibly T_i. Also improve some log messages.
| * Retain pid_error_sum and pid_delta between votes.Mike Perry2011-11-17
| | | | | | | | | | pid_delta is stored for informational purposes only. However, missing pid_error_sum for Guard measurements w/o feedback was a bug.
| * Move more parameters to consensus.Mike Perry2011-11-17
| |
| * Fix for 0-bandwidth Guard issue.Mike Perry2011-11-17
| | | | | | | | We were accidentally voting 0 for guards that weren't measured this round.
| * Tweak a regex and add some log lines.Mike Perry2011-11-14

| * Tweaks to try to make PID look more like other bw auths.Mike Perry2011-11-14
| | | | | | | | | | | | | | | | Just to make sure something crazy is not going on, let's try eliminating the circ failure dampening, and re-instate the "larger ratio" idea for PID control. With these both re-enabled, PID "feedback" should look more similar to the other bandwidth auths, because with just one auth running the code, there is no feedback.
| * Bug #4268: Remove sleeping from bw authsMike Perry2011-11-14
| | | | | | | | | | Code is still there, just disabling via config, and adding a check to ensure the time isn't negative.
| * Bug #4273: Reduce max fetch timeMike Perry2011-11-14
| | | | | | | | | | 5 minutes seems better. Now that we automatically select slice file sizes to complete in about 5 seconds, it should be more than enough.
| * Prior to feedback, we used the greater of two ratios.Mike Perry2011-11-14
| | | | | | | | | | Let's keep this behavior in place when the bwauthpid consensus param is missing.
| * Bugs 4431+2014: Randomized url support + variable file sizes.Mike Perry2011-11-14
| | | | | | | | Scanner child piece.
| * Bug #4431: Automatically determine size cutoffs.Mike Perry2011-11-14
| | | | | | | | Also update the spec and the use of Wgd.
| * Fix accidental reset of circ_fail_rate.Mike Perry2011-11-14

| * Submodule.Mike Perry2011-11-14
