Fabian Reinartz 8e1f97fad4 wal: add write ahead log package 
This adds a new WAL that's agnostic to the actual record contents.
It's much simpler and should be more resilient than the existing one.

Merge pull request #348 from BenoitKnecht/fix-block-boundaries 
Make sure blocks don't overlap to avoid outsider chunks
 2018-07-05 12:54:34 +02:00
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.

Benoît Knecht 1e1b2e163d Make interval overlap comparisons more explicit 
Blocks are half-open intervals [a, b), while all other intervals
(chunks, head, ...) are closed intervals [a, b].

Make that distinction explicit by defining `OverlapsClosedInterval()`
methods for blocks and chunks, and using them in place of the more
generic `intervalOverlap()` function.

This change also fixes `db.Querier()` and `db.Delete()`, which could
previously return one extraneous block at the end of the specified
interval.

Benoît Knecht 0e4be5226a db: block MaxTime should not be part of the block 
Block intervals are bound by `block.MinTime`, `block.MaxTime`, but they
define a half-open interval: `[block.MinTime, block.MaxTime).

However, when deciding if a chunk was part of a block or not, the
`intervalOverlap()` function would consider both the chunk and the block
intervals as being closed.

Rather than modify the login in `intervalOverlap()`, we explicitly
remove the last value from the interval when reading from head to
persist blocks.
