Brian Brazil	6ac81cc7a9	Correctly handle empty labels. (#594 ) Currently a time series with empty labels is not treated the same as one with missing labels. Currently this can only come from ALERTS&ALERT_FOR_STATE so it's unlikely anyone has actually hit it. Signed-off-by: Brian Brazil <brian.brazil@robustperception.io>	7 years ago

Krasi Georgiev	c3ffdf1a99	Test createBlock and check all os.RemoveAll in the tests for errors. (#549 ) Testing that createBlock creates blocks that can be opened. and checking the os.RemoveAll for errors will catch errors for un-closed files under windows. Many missing .Close() calls were added for fixing failing os.RemoveAll Signed-off-by: Krasi Georgiev <kgeorgie@redhat.com>	7 years ago

mknapphrt	ebf5d74325	Added storage size based retention method and new metrics (#343 ) Added methods needed to retain data based on a byte limitation rather than time. Limitation is only applied if the flag is set (defaults to 0). Both blocks that are older than the retention period and the blocks that make the size of the storage too large are removed. 2 new metrics for keeping track of the size of the local storage folder and the amount of times data has been deleted because the size restriction was exceeded.

Brian Brazil	d50b9a5619	Reload after reading the WAL. (#460 ) This causes the head to be GCed at startup, removing any series that were read from the WAL but have since been written to a block.

Fabian Reinartz	7841d417b3	Ensure blocks are time-ordered in memory We assume in multiple places that the block list held by DB has blocks sequential by time. A regression caused us to hold them ordered by ULID, i.e. by creation time instead. Signed-off-by: Fabian Reinartz <freinartz@google.com>	8 years ago
Benoît Knecht	24b223c161	db: add test for Querier returning too many blocks Due to the way blocks used to overlap by 1 millisecond (see #347), when requesting a 2-hour interval starting at `blocks[1].MinTime`, the `Querier` would consider three blocks: `blocks[0]`, `blocks[1]` and `blocks[2]`, because `blocks[0].MaxTime` and `blocks[2].MinTime` were in that interval. However, if the blocks don't overlap, only two blocks should be returned: `blocks[1]` and `blocks[2]`. This test ensures that it's indeed the case.
