query: Metrics missing when using query component

[rsommer]

Thanos, Prometheus and Golang version used

thanos, version 0.2.1 (branch: HEAD, revision: 30e7cbdafd3ef01189f202945c2728fcf37e1cf1)
  build user:       root@79ffcf51ff9b
  build date:       20181227-15:44:56
  go version:       go1.11.4

prometheus, version 2.6.0 (branch: HEAD, revision: dbd1d58c894775c0788470944b818cc724f550fb)
  build user:       root@bf5760470f13
  build date:       20181217-15:14:46
  go version:       go1.11.3

What happened
I recently did setup thanos for long term metric storage. After the first few weeks of running the setup, I tried to zoom out in grafana to see how everything works out. While zooming out to 30 days in grafana, I started to see gaps in the displayed metrics. There is metric data for the selected time range. If I do query prometheus directly, I get the expected results.

What you expected to happen
Getting all existing data when querying via thanos query.

Full logs to relevant components

hi, it seems to be as same as this issue, it has been fixed in this PR.

You could try to upgrade the Thanos with the newest master head or wait for the 0.3.0 version, the new version will come soon.

@jojohappy you're right, I just built thanos from the master branch and the problem has gone away. I did miss the referenced bug, sorry for the duplication.
