* tsdb/agent: Fix deadlock from simultaneous GC and write This commit fixes a potential deadlock where storing in-memory series references could deadlock with a WAL GC cycle. Signed-off-by: Robert Fratto <robertfratto@gmail.com> * add missing license header Signed-off-by: Robert Fratto <robertfratto@gmail.com> * order local imports Signed-off-by: Robert Fratto <robertfratto@gmail.com> * align deadlock testing with discovery/manager_test.go method Also prevents GCs from running concurrently, which could also cause a deadlock (even though it's currently impossible for two GCs to run concurrently).

TSDB
This directory contains the Prometheus TSDB (Time Series DataBase) library, which handles storage and querying of all Prometheus v2 data.
Due to an issue with versioning, the "latest" docs shown on Godoc are outdated. Instead you may use the docs for v2.31.1
