plugin/pkg/uniq: add (#1733) Spin this out the metrics package so we can use it in the health one of well to fix some reload bugs. 2018-04-25 11:45:09 +01:00			`package uniq`

plugin/metrcs: fix datarace on listeners (#2835) This fixes a data race on the listener(s) that get started in the metrics plugins. It also restore pkg/uniq to its former glory and removes and state being carried in there; this means for metrics that registry.go was to replicate that behavior with locking (as pkg/uniq doesn't do, or need that). Also renamed uniqAddr to just u, to make it slightly shorter. Signed-off-by: Miek Gieben <miek@miek.nl> 2019-05-18 18:34:46 +01:00			`u.Set("test", func() error { i++; return nil })`
