Handle closed target provider channel
 2016-03-08 17:02:05 +01:00
Fabian Reinartz 56fc9bdff3 Handle closed target provider channel 
This fixes the case where a target provider closes the update
channel and exits before the context is canceled.
This should only be true for the static provider but it's safer
to generally handle this case.

beorn7 f193f2b8ef Add a command to promtool that dumps metadata of heads.db 
I needed this today for debugging. It can certainly be improved, but
it's already quite helpful.

I refactored the reading of heads.db files out of persistence, which
is an improvement, too.

I made minor changes to the cli package to allow outputting via the
io.Writer interface.

beorn7 0ea5801e47 Handle errors caused by data corruption more gracefully 
This requires all the panic calls upon unexpected data to be converted
into errors returned. This pollute the function signatures quite
lot. Well, this is Go...

The ideas behind this are the following:

- panic only if it's a programming error. Data corruptions happen, and
  they are not programming errors.

- If we detect a data corruption, we "quarantine" the series,
  essentially removing it from the database and putting its data into
  a separate directory for forensics.

- Failure during writing to a series file is not considered corruption
  automatically. It will call setDirty, though, so that a
  crashrecovery upon the next restart will commence and check for
  that.

- Series quarantining and setDirty calls are logged and counted in
  metrics, but are hidden from the user of the interfaces in
  interface.go, whith the notable exception of Append(). The reasoning
  is that we treat corruption by removing the corrupted series, i.e. a
  query for it will return no results on its next call anyway, so
  return no results right now. In the case of Append(), we want to
  tell the user that no data has been appended, though.

Minor side effects:

- Now consistently using filepath.* instead of path.*.

- Introduced structured logging where I touched it. This makes things
  less consistent, but a complete change to structured logging would
  be out of scope for this PR.
