Switches TranslogStreams to check a header in the file to determine the
translog format, delegating to the version-specific stream.
Version 1 of the translog format writes a header using Lucene's
CodecUtil at the beginning of the file and appends a checksum for each
translog operation written.
Also refactors much of the translog operations, such as merging
.hasNext() and .next() in FsChannelSnapshot
Relates to #6554
These caches have no advantage compared to the default node cache. Additionally,
the soft cache makes use of soft references which make fielddata loading quite
unpredictable in addition to pushing more pressure on the garbage collector.
The `none` cache is still there because of tests. There is no other good
reason to use it.
LongFieldDataBenchmark has been removed because the refactoring exposed a
compilation error in this class, which seems to not having been working for a
long time. In addition it's not as much useful now that we are progressively
moving more fields to doc values.

This also fixes has_parent filters with a nested empty bool filter
(see test SimpleChildQuerySearchTests#test6722, the test should actually expect
either 0 results when searching for has_parent "test" or one result when
search for has_parent "foo")

Complex explanations were always read as Explanations. Depending
on if the response was streamed or not the explanation was
therefore generated by a ComplexExplanation or by a regular
Explanation.

Added the ability to register template filters that are being applied when a new index is created. The default filter that checks whether the template pattern matches the index name always runs first, additional filters can also be registered so that templates can be filtered out based on custom logic.
Took the chance to add the handy source(Object... source) method to PutIndexTemplateRequest and corresponding builder
Closes#7459Closes#7454
This change forces the GetRequest when a script is being loaded from an index
to use preference("_local") and threaded(false) to prevent the script service from
forking for GetRequests.
The comparison and read code in the BlobStoreIndexShardRepository
used the physicalName and Name in reverse order. This caused
SnapshotBackwardsCompatibilityTest to fail.
This reverts commit 636af40da1
The "optimized" encoders/decoders have been unreliable and error prone.
Also, fix LZFCompressor.compress to use LZFEncoder.safeEncode, which
creates a new safe encoder, instead of using a shared encoder (which
is not threadsafe).
closes#7468
Due to additional safety added in #7351 we compute now a strong hash for
.si and segments_N files which are compared during snapshot / restore.
Old snapshots don't have this hash which can cause unnecessary copying
of large amount of data. This commit adds the ability to fetch this
hash from the blob store if needed.
Closes#7434
Today we have a small window where a searcher can be acquired but the
engine is in the state of starting up. This causes a NPE triggering a
shard failure if we are fast enough. This commit fixes this situation
gracefully.

- _all field was never merged when mapping was updated and no conflict reported
- _all accepted doc_values format although it is always tokenized

It's risky to have our own snapshot of Java 8's ConcurrentHashMap:
unless we keep the sources in sync over time (and OpenJDK's version
had already diverged), then we won't get bug/performance fixes. Users
can choose to upgrade to Java 8 to see the improvements of CHM.
Closes#7392Closes#7296
Shard requests like broadcast delete and delete by query, that needs to be executed on primary and all replicas, get read and written out to the transport on the same node. That means that if we add some field version checks are not enough to maintain bw comp since a newer node that holds the primary might receive the request from an older node, that didn't provide the field. Yet, when writing the request out again to a newer node that holds the replica, we do try and serialize the field although it's missing. The newer fields just needs to be set to optional in these cases, in addition to the version checks.
Re-enabled testDeleteByQuery and testDeleteRoutingRequired bw comp tests since this was the cause of their failures.
Closes#7406
The verifyThreadNames starts a node and checks that all new threads on the JVM are properly named. The current test uses the name of the new node which sometimes fails because our shared cluster spawns a new thread which is properly named but for not for the new name.
The commits relaxes the requirement of the test and on verify the threads are properly named (but not necessarily of the new node)
