When a shard becomes in active we trigger a sync flush in order to speed up future recoveries. The sync flush causes a new translog generation to be made, which in turn confuses the IndexingMemoryController making it think that the shard is active. If no documents comes along in the next 5m, the shard is made inactive again , triggering a sync flush and so forth.
To avoid this, the IndexingMemoryController is changed to ignore empty translogs when checking if a shard became active. This comes with the price of potentially missing indexing operations which are followed by a flush. This is acceptable as if no more index operation come in, it's OK to leave the shard in active.
A new unit test is introduced and comparable integration tests are removed.
Closes#13802
Instead just log the same thing we print to the startup console for that case (magic logic),
it sucks to do this, but guice exceptions are too much.
All other non-guice exceptions will still be fully logged.
Closes#13782
This commit adds explicit ids for managing ElasticsearchException
serialization. By adding explicit ids and unit tests for them, the ids
are less brittle and breakage can be more clearly detected.
Today we use reflection where it's not needed anymore since java8 can
pass ctors around. This commit replaces runtime checks with compile time
checks which is always preferrable.
These classes are really duplicates and are just here for historical reasons.
We don't need these anymore since the same classes exist in lucene today.
This also removes the guice injection for DeletionPolicy and make them shard private.
TermsLookupQueryBuilder was left around only for bw comp reasons, but TermsQueryBuilder is its replacement. We can remove it now that it is clear query refactoring goes in master (3.0).
There is no need to have term vectors service on the shard level where it's
created for every shard. This commit moves it to a higher level which makes
shard creation slightly simpler and reduces the number of long living objects.
Before the refactoring we didn't check any invalid settings for strategy and relation
in the GeoShapeQueryBuilder. However, using SpatialStrategy.TERM and ShapeRelation.INTERSECTS
together is invalid and we tried to protect against that in the validate() method.
This PR moves these checks to setter for strategy and relation and adds tests for the new
behaviour.

Block execve(), fork(), and vfork() system calls, returning EACCES instead,
on kernels that support seccomp-bpf: either via seccomp() or falling back
to prctl().
Only linux/amd64 is supported. This feature can be disabled (in case
of problems) with bootstrap.seccomp=false.

Some methods had default implementation while queries were going to be refactored, now that they are all refactored all those methods can be made abstract.
Remove ParseFieldMatcher duplication query in both contexts. QueryParseContext is still contained in QueryShardContext, as parsing still happens in the shards here and there. Most of the norelease comments have been removed simply because the scope of the refactoring has become smaller. Some could only be removed once everything, the whole search request, gets parsed on the coordinating node. We will get there eventually.
SimpleIndexQueryParserTests was the main responsible: deleted lots of duplicated tests, moved the ones that made sense to keep to their corresponding unit tests (note they were ESSingleNode tests before while are now converted to unit tests).
Closes#13750
After all queries now have a `toQuery` method and the parsers all
support `fromXContent` it is possible to remove the following
workarounds and deprecated methods we kept around while doing the
refactoring:
* remove the BaseQueryParser and BaseQueryParserTemp. All parsers
implement QueryParser directly now
* remove deprecated methods in QueryParseContext that either returned
a Query or a Filter.
* remove the temporary QueryWrapperQueryBuilder
Relates to #10217
The IndexingMemoryController checks periodically if there is any indexing activity on the shard. If no activity is sean for 5m (default) the shard is marked as inactive allowing it's indexing buffer quota to given to other active shards.
Sadly the current check is bad as it checks for 0 translog operation. This makes the inactive wait for a flush to happen - which used to take 30m and since #13707 doesn't happen at all (as we rely on the synced flush triggered by inactivity). This commit fixes the check so it will work with any translog size.
Closes#13759
