This is a standalone wrapper around Mockito, it allows us to use
it without granting dangerous permissions to all of our code.

Today we keep track of how often filters are used at the index level in order
to decide whether they should be cached or not. This is an issue if you have
several shards of the same index on the same node as it will multiply statistics
by the number of shards that you have for this index on the node, which defeats
the purpose of waiting for a filter to be reused before caching them.
If the translog UUID is corrupted we should not convert it
to UTF-8 since it might be invalid. Instead we should compare
the UTF-8 byte representation directly.
This more consistent with the other logging it makes and since it can be used in many operations the output can be more verbose (without adding too much info as to who timed out exactly - which we can fix separately). If need be the caller of the observer can log a higher level message.
Closes#11722
In order to be more consistent with what they do, the query cache has been
renamed to request cache and the filter cache has been renamed to query
cache.
A known issue is that package/logger names do no longer match settings names,
please speak up if you think this is an issue.
Here are the settings for which I kept backward compatibility. Note that they
are a bit different from what was discussed on #11569 but putting `cache` before
the name of what is cached has the benefit of making these settings consistent
with the fielddata cache whose size is configured by
`indices.fielddata.cache.size`:
* index.cache.query.enable -> index.requests.cache.enable
* indices.cache.query.size -> indices.requests.cache.size
* indices.cache.filter.size -> indices.queries.cache.size
Close#11569
In order to be backwards compatible, indices created before 2.x must support
indexing of a unix timestamp and its configured date format. Indices created
with 2.x must configure the `epoch_millis` date formatter in order to
support this.

Today we are very lenient in parsing the translog files. This is
actually not necessary since we have a clear run once upgrade path.
All files are converted into the new file name pattern such that we
only need to look at old file patterns in the context of the upgrade.
This commit makes parsing really strict with the exceptoin of the upgrade path.
This adds a new pipeline aggregation, the cumulative sum aggregation. This is a parent aggregation which must be specified as a sub-aggregation to a histogram or date_histogram aggregation. It will add a new aggregation to each bucket containing the sum of a specified metrics over this and all previous buckets.
Today we mark a translog as upgraded by adding a marker to the engine commit.
Yet, this commit was only added if there was no translog present before ie. only
if we have a fresh engine which is missing the entire point. Yet, this commit
adds a backwards index tests that ensures we can open old indices more than once
ie. mark the index as upgraded.
Closes#11858
In Lucene 5x the exception thrown when highlighter encounters a huge term
is a BytesRefHash.MaxBytesLengthExceededException but in Lucene 4x it is
wrapped in a RuntimeException. Therefore, it seems saver to unwrap this.
There was only a single actual "use" of close, for a threadlocal
in VersionFieldMapper. However, that threadlocal is completely
unnecessary, so this change removes the threadlocal and
close() altogether.
This commit consolidates several abstractions on the shard level in
ordinary classes not managed by the shard level guice injector.
Several classes have been collapsed into IndexShard and IndexShardGatewayService
was cleaned up to be more lightweight and self-contained. It has also been moved into
the index.shard package and it's operation is renamed from recovery from "gateway" to recovery
from "store" or "shard_store".
Closes#11847
