Removed null check for token, if we are outside the null it already means it is null.
Fixed typo in comment and remove leftover assignment to unused local variable.
Netty3/4 TcpTransport implementations are creating thread factories with a "http_server" thread prefix whereas it should start with "transport_server" and let the "http_server" prefix for the HttpServerTransport implementations.
This test is periodically failing. As I suspect that the GCDisruption scheme is somehow making the wrong node block on
its cluster state update thread, I've added some more logging and a thread dump once the given assertion triggers
again.
today we fsync in a blocking fashion where all threads block while another
syncs. Yet, we can improve this and make use of the async infrastrucutre added
for `wait_for_refresh` and make fsyncing single threaded while all other threads
can continue indexing. The syncing thread then notifies a listener once the requests
location is synced. This also allows to send docs to replicas before its actually fsynced
allowing for cocurrent replica processing.
This patch has a significant impact on performance on slower discs. An initial single node benchmark
shows that on very fast SSDs there is no noticable impact but on slow spinning disk this
patch shows a ~32% performance improvement.

Currently, after at least one pipeline is registered it is getting rebuilt on every single cluster state update, even when this update is not related to ingest metadata. This change adds a check that the ingest metadata changed before trying to rebuild all pipelines.
Adds an explicit recoverySource field to ShardRouting that characterizes the type of recovery to perform:
- fresh empty shard copy
- existing local shard copy
- recover from peer (primary)
- recover from snapshot
- recover from other local shards on same node (shrink index action)
* Fix NPE during search with source filtering if the source is disabled.
Instead of throwing an NPE, a search response with source filtering will not contain the source if it is disabled in the mapping.
Closes#7758
* Created unit tests for FetchSourceSubPhase. Tests similar to SourceFetchingIT.
Removed SourceFetchingIT#testSourceDisabled (now covered via unit test FetchSourceSubPhaseTests#testSourceDisabled).
* Updated FetchSouceSubPhase unit tests per comments.
Renamed main unit test method.
Use assertEquals and assertNull instead of assertThat (less code).
Fixes an issue where the value for the `script.engine.<lang>.inline`
settings would be _set_ properly, but would not accurately be reflected
in the `include_defaults` output. Adds a test to ensure the default raw
setting is now correct.
Resolves#20159
* Make sure indexBoost is serialized in a consistent order
* remove hasIndexBoost by using indexBoost size
* Make sure phrase suggester's collateParams is serialized in consistent
order
* Make StreamOutput writer to serialize maps in consistent order
The class Setting holds a static reference to a deprecation logger
instance. When the class initializer for Setting runs, it starts
triggering log4j initialization. There is a chain of initializations
from InternalSettingsPreparer to Environment to Setting that triggers
this initialization before log4j configuration has occurred. This commit
modifies this initialization so that initialization is not done eagerly.

This makes GET operations more consistent with `_search` operations which expect
`(stored_)fields` to work on stored fields and source filtering to work on the
`_source` field. This is now possible thanks to the fact that GET operations
do not read from the translog anymore (#20102) and also allows to get rid of
`FieldMapper#isGenerated`.
The `_termvectors` API (and thus more_like_this too) was relying on the fact
that GET operations would extract fields from either stored fields or the source
so the logic to do this that used to exist in `ShardGetService` has been moved
to `TermVectorsService`. It would be nice that term vectors do not rely on this,
but this does not seem to be a low hanging fruit.
Non-stale shard copies are currently tracked using their allocation ids in the cluster state. When a node leaves the cluster, shard copies of that node are marked as stale by removing their allocation ids from the active set in the cluster. For full cluster restarts, this can have the unwanted effect that only the last node holding a copy of the shard will be seen as non-stale. The other shard copies are not really stale though as long as no writes have happened on this shard copy. Shard copies should thus only be marked as stale (by the master in the cluster state) if other active shards have received writes.
This commit implements the above logic and also renames the persistent structure used to track non-stale shard copies from "active_allocations" to "in_sync_allocations" as we now also support tracking non-stale shard copies that have no active routing entries in the cluster state.
We need to get the string representation of numbers in order to include in
`_all`. However this has a cost and disabling `_all` is rather common so we
should look into skipping it.
The network types in use on a cluster can be useful information to have,
so this commit adds aggregate metrics for the network types in use in a
cluster to the cluster stats.

This moves the Writer interface from StreamOutput into Writeable, as a peer of its inner Reader interface. This should hopefully help to avoid random functional interfaces being created for the same purpose.
It also makes use of the moved class by updating writeMapOfLists and readMapOfLists.
This removes final from the RestClient, Response, and Sniffer classes so that outside code can mock them. Their constructors are already package private, so there's not much that can go wrong.
Objects hierarchy must be tracked when entering/leaving an object so that it better knows if the "newField" has been inserted into an arbitrary holding object.
Can be reproduced with gradle :core:test -Dtests.seed=760F8BD0F7E46D45 -Dtests.class=org.elasticsearch.index.query.MoreLikeThisQueryBuilderTests -Dtests.method="testUnknownObjectException" -Dtests.security.manager=true -Dtests.locale=ko -Dtests.timezone=Etc/Zulu
The Netty 4 HTTP server pipeline tests contains two different test
cases. The general idea behind these tests is to submit some requests to
a Netty 4 HTTP server, one test with pipelining enabled and another test
with pipelining disabled. These requests are submitted to two endpoints,
one with a path like /{id} and another with a path like /slow with a
query string parameter sleep. This parameter tells the request handler
how long to sleep for before replying. The idea is that in the case of
the pipelining enabled tests, the requests should come back exactly in
the order submitted, even with some of the requests hitting the slow
endpoint with random sleep durations; this is the guarantee that
pipelining provides. And in the case of the pipelining disabled tests,
requests were randombly submitted to /{id} and /slow with sleep
parameters starting at 600ms and increasing by 100ms for each slow
request constructed. We would expect the requests to come back with the
all the responses to the /{id} requests first because these requests
will execute instantaneously, and then the responses to the /slow
requests. Further, it was expected that the slow requests would come
back ordered by the length of the sleep, the thinking being that 100ms
should be enough of a difference between each request that we would
avoid any race conditions. Sadly, this is not the case, the threads do
sometimes hit race conditions.
This commit modifies the HTTP server pipelining tests to address this
race condition. The modification is that the query string parameter on
the /slow endpoint is removed in favor of just submitting requests to
the path /slow/{id}, where id just used a marker to distinguish each
request. The server chooses a random sleep of at least 500ms for each
request on the slow path. The assertion here then is that the /{id}
responses arrive first, then then /slow responses. We can not make an
assertion on the order of the responses, but we can assert that we did
see every expected response.

When need to check the whole hierarchy of objects to know if the newly inserted "newField" object is part of an arbitrary holding object or not.
Reproduced with `gradle :modules:percolator:test -Dtests.seed=736B0B67DA7A3632 -Dtests.class=org.elasticsearch.percolator.PercolateQueryBuilderTests -Dtests.method="testUnknownObjectException" -Dtests.security.manager=true -Dtests.locale=es-ES -Dtests.timezone=ART`
Previous to this change the nesting of aggregation profiling results
would be incorrect when the request contains a terms aggregation and the
collect mode is (implicitly or explicitly) set to `breadth_first`. This
was because the aggregation profiling has to make the assumption that
the `preCollection()` method of children aggregations is always called in
the `preCollection()` method of their parent aggregation. When the collect
mode is `breadth_first` the `preCollection` of the children aggregations
was delayed until the documents were replayed.
This change moves the `preCollection()` of deferred aggregations to run
during the `preCollection()` of the parent aggregation. This should have
no adverse impact on the breadth_first mode as there is no allocation of
memory in any of the aggregations.
We also apply the same logic to the diversified sampler aggregation as
we did to the terms aggregation to move the `preCollection()` of the
child aggregations method to be called during the `preCollection()` of
the parent aggregation.
This commit also includes a fix so that the `ProfilingLeafBucketCollector`
propagates the scorer to its delegate so the diversified sampler agg works
when profiling is enabled.
