Brad Fitzpatrick	7c1d6e35a5	all: use Go 1.22 range-over-int Updates #11058 Change-Id: I35e7ef9b90e83cac04ca93fd964ad00ed5b48430 Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	3 weeks ago
Joe Tsai	7732377cd7	tstime/rate: implement Value.{Marshal,Unmarshal}JSON (#8481 ) Implement support for marshaling and unmarshaling a Value. Updates tailscale/corp#8427 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	4 months ago
Andrew Lytvynov	1302bd1181	all: cleanup unused code, part 1 (#10661 ) Run `staticcheck` with `U1000` to find unused code. This cleans up about a half of it. I'll do the other half separately to keep PRs manageable. Updates #cleanup Signed-off-by: Andrew Lytvynov <awly@tailscale.com>	5 months ago
Joe Tsai	87b4bbb94f	tstime/rate: add Value (#7491 ) Add Value, which measures the rate at which an event occurs, exponentially weighted towards recent activity. It is guaranteed to occupy O(1) memory, operate in O(1) runtime, and is safe for concurrent use. Signed-off-by: Joe Tsai <joetsai@digital-static.net>	1 year ago
Will Norris	71029cea2d	all: update copyright and license headers This updates all source files to use a new standard header for copyright and license declaration. Notably, copyright no longer includes a date, and we now use the standard SPDX-License-Identifier header. This commit was done almost entirely mechanically with perl, and then some minimal manual fixes. Updates #6865 Signed-off-by: Will Norris <will@tailscale.com>	1 year ago
Brad Fitzpatrick	da8def8e13	all: remove old +build tags The //go:build syntax was introduced in Go 1.17: https://go.dev/doc/go1.17#build-lines gofmt has kept the +build and go:build lines in sync since then, but enough time has passed. Time to remove them. Done with: perl -i -npe 's,^// \+build.*\n,,' $(git grep -l -F '+build') Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Brad Fitzpatrick	6a2e94cbeb	tstime/rate: deflake TestLongRunningQPS even more Previous de-flakings: * `8cf1af8a07` for #3733 * `30458c71c8` for #2727 Fixes #4044 Change-Id: I506cf1ff37bb224f5a9929f1998901e60b24535d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Josh Bleecher Snyder	8cf1af8a07	tstime/rate: deflake TestLongRunningQPS This test set the bar too high. Just a couple of missed timers was enough to fail. Change the test to more of a sanity check. While we're here, run it for just 1s instead of 5s. Prior to this change, on a 13" M1 MPB, with stress -p 512 ./rate.test -test.run=QPS I saw 90%+ failures. After this change, I'm at 30k runs with no failures yet. Fixes #3733 Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	2 years ago
Joe Tsai	30458c71c8	tstime/rate: deflake TestLongRunningQPS This test is highly dependent on the accuracy of OS timers. Reduce the number of failures by decreasing the required accuracy from 0.999 to 0.995. Also, switch from repeated time.Sleep to using a time.Ticker for improved accuracy. Updates #2727 Signed-off-by: Joe Tsai <joetsai@digital-static.net>	3 years ago
Josh Bleecher Snyder	9da4181606	tstime/rate: new package This is a simplified rate limiter geared for exactly our needs: A fast, mono.Time-based rate limiter for use in tstun. It was generated by stripping down the x/time/rate rate limiter to just our needs and switching it to use mono.Time. It removes one time.Now call per packet.
