* test: use `T.TempDir` to create temporary test directory
This commit replaces `os.MkdirTemp` with `t.TempDir` in tests. The
directory created by `t.TempDir` is automatically removed when the test
and all its subtests complete.
Prior to this commit, temporary directory created using `os.MkdirTemp`
needs to be removed manually by calling `os.RemoveAll`, which is omitted
in some tests. The error handling boilerplate e.g.
defer func() {
if err := os.RemoveAll(dir); err != nil {
t.Fatal(err)
}
}
is also tedious, but `t.TempDir` handles this for us nicely.

multiple users have attempted to run influxdb in a docker container
with a windows host and a volume mounted from windows. that causes
problems because it apparently uses samba/cifs which does not
support fsync on directories. this patchset will, if it receives an EINVAL
on directory fsync, as is what appears to happen on samba/cifs, then it
will ignore it. this should help.
fixes#9833.
fixes#9630.
This improvement avoids performing a binary search on the index by
first checking the key against the lower and upper bounds. Particularly
useful for multiple, fully-compacted TSM files.
callers can always ensure that the observer set on the engine options
is appropriate for that shard id. this simplifies the api and reduces
the chance of bugs due to mixing up shard ids.
If multiple tombstones exists for a series that ended up causing the
full data to be deleted, the blocks were not removed from the offsets
in the index. This causes the TSMReader to report that a key exist
but does not have any data.
During a compaction, every key should have at least one value. Since
this invariant was broken, the compaction aborted early and ends up
dropping all series keys that are lexigraphically greater than where
the breakage occured. This would cause data to be dropped during the
compaction.
This fixes a potential bug where the BlockIterator would skip blocks
if the underlying TSMReader had deletes on it concurrently. This
could possibly occur due to changes in 91eb9de3 that now use the
existing TSMReaders from the FileStore instead of creating new ones
during compaction.
This instructs the kernel that it can release memory used by mmap'd
TSM files when they are not actively being used. It the mappings are
use, the kernel will fault the pages back in. On linux, this causes
RES memory to drop immediately when run.
This switches all the interfaces that take string series key to
take a []byte. This eliminates many small allocations where we
convert between to two repeatedly. Eventually, this change should
propogate futher up the stack.
* introduced UnsignedValue type
* leveraged existing int64 compression algorithms (RLE, Simple 8B)
* tsm and WAL can read and write UnsignedValue
* compaction is aware of UnsignedValue
* unsigned support to model, cursors and write points
NOTE: there is no support to create unsigned points, as the line
protocol has not been modified.
The min key was not used in OverlapsKeyRange which caused it to return
false when it should be true. This causes a bug where deletes would not
write tombstones for files that actually contained the data it was supposed
to delete.
Tombstone files would be written to all TSM files even if the deleted
keys or timerange did not exist in the TSM file. This had the side
effect of causing shards to get recompacted back to the same state. If
any shards or large numbers of TSM files existed, disk usage and CPU
utilization would spike causing issues.
This prevents tombstones being written for TSM files that could not
possiby contain the series keys being deleted or if the delted time
range is outside the range of the file.
Each shard has a number of goroutines for compacting different levels
of TSM files. When a shard goes cold and is fully compacted, these
goroutines are still running.
This change will stop background shard goroutines when the shard goes
cold and start them back up if new writes arrive.
This reworks drop measurement to use a sorted list of series keys
instead of creating an intermediate map. It remove allocations
and some extra garbage that is created during drop measurement.
