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 c13b1ecfe9 Make chunk iterators more DRY
This finally extracts all the common code of the two chunk iterators
into one. Any future chunk encodings with fast access by index can use
the same iterator by simply providing an indexAccessor. Other future
chunk encodings without fast index access (like Gorilla-style) can
still implement the chunkIterator interface as usual.

beorn7 32f280a3cd Slim down the chunkIterator interface
For one, remove unneeded methods.

Then, instead of using a channel for all values, use a
bufio.Scanner-like interface. This removes the need for creating a
goroutine and avoids the (unnecessary) locking performed by channel
sending and receiving.

This will make it much easier to write new chunk implementations (like
Gorilla-style encoding).

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 75a6b460ef Give TestEvictAndLoadChunkDescs more time to actually evict
Obviously, it's really bad to depend on timing here. The proper fix
would be to have something like WaitForIndexing for other things to
wait for, too.

For now, let's see if the wait time increase fixes the issue.

beorn7 fc7de5374a Quarantine series upon problem writing to the series file
This fixes https://github.com/prometheus/prometheus/issues/1059 , but
not in the obvious way (simply not updating the persist watermark,
because that's actually not that simple - we don't really know what
has gone wrong exactly). As any errors relevant here are most likely
caused by severe and unrecoverable problems with the series file,
Using the now quarantine feature is the right step. We don't really
have to be worried about any inconsistent state of the series because
it will be removed for good ASAP. Another plus is that we don't have
to declare the whole storage dirty anymore.

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.

Fabian Reinartz d89c254849 Make copying alerting state safer.
This considers static labels in the equality of alerts to
avoid falsely copying state from a different alert definition with
the same name across reloads.

To be safe, it also copies the state map rather than just its pointer
so that remaining collisions disappear after one evaluation interval.
