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>	2 years ago
Joe Tsai	9a05cdd2b5	syncs: add Map (#6260 ) Map is a concurrent safe map that is a trivial wrapper over a Go map and a sync.RWMutex. It is optimized for use-cases where the entries change often, which is the opposite use-case of what sync.Map is optimized for. The API is patterned off of sync.Map, but made generic.

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	4950fe60bd	syncs, all: move to using Go's new atomic types instead of ours Fixes #5185 Change-Id: I850dd532559af78c3895e2924f8237ccc328449d Signed-off-by: Brad Fitzpatrick <bradfitz@tailscale.com>	2 years ago
Josh Bleecher Snyder	997b19545b	syncs: use TryLock and TryRLock instead of unsafe The docs say: Note that while correct uses of TryLock do exist, they are rare, and use of TryLock is often a sign of a deeper problem in a particular use of mutexes. Rare code! Or bad code! Who can tell! Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	a5da4ed981	all: gofmt with Go 1.17 This adds "//go:build" lines and tidies up existing "// +build" lines. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	3 years ago

Josh Bleecher Snyder	d3ba860ffd	syncs: stop running TestWatchMultipleValues on CI It's flaky, and not just on Windows. Signed-off-by: Josh Bleecher Snyder <josharian@gmail.com>	4 years ago
Josh Bleecher Snyder	0807e3e2f7	syncs: disable TestWatchMultipleValues on Windows CI builds The Windows CI machine experiences significant random execution delays. For example, in this code from watchdog.go: done := make(chan bool) go func() { start := time.Now() mu.Lock() There was a 500ms delay from initializing done to locking mu. This test checks that we receive a sufficient number of events quickly enough. In the face of random 500ms delays, unsurprisingly, the test fails. There's not much principled we can do about it. We could build a system of retries or attempt to detect these random delays, but that game isn't worth the candle. Skip the test. Signed-off-by: Josh Bleecher Snyder <josh@tailscale.com>	4 years ago
