This is related to #27260. Currently there is a setting
http.read_timeout that allows users to define a read timeout for the
http transport. This commit implements support for this functionality
with the transport-nio plugin. The behavior here is that a repeating
task will be scheduled for the interval defined. If there have been
no requests received since the last run and there are no inflight
requests, the channel will be closed.
After changing the allowed minimum value for min_children in has_child query from 0 to 1 in
the next major version, this PR adds a deprecation warning for these cases.
Closes#41548
Motivated by slow snapshot deletes reported in e.g. #39656 and the fact that these likely are a contributing factor to repositories accumulating stale files over time when deletes fail to finish in time and are interrupted before they can complete.
* Makes snapshot deletion async and parallelizes some steps of the delete process that can be safely run concurrently via the snapshot thread poll
* I did not take the biggest potential speedup step here and parallelize the shard file deletion because that's probably better handled by moving to bulk deletes where possible (and can still be parallelized via the snapshot pool where it isn't). Also, I wanted to keep the size of the PR manageable.
* See https://github.com/elastic/elasticsearch/pull/39656#issuecomment-470492106
* Also, as a side effect this gives the `SnapshotResiliencyTests` a little more coverage for master failover scenarios (since parallel access to a blob store repository during deletes is now possible since a delete isn't a single task anymore).
* By adding a `ThreadPool` reference to the repository this also lays the groundwork to parallelizing shard snapshot uploads to improve the situation reported in #39657
The subfields of the search_as_you_type are prefixed with the name of their root field.
However they should used the full path of the root field rather than just the name since
these fields can appear in a multi-`fields` definition or under an object field.
Since this field type is not released yet, this should be considered as a non-issue.
This adds a gradle task called generateContextDoc in the Painless module. The
task will start a cluster, issue commands against the context rest api for
Painless, and generate documentation for each API per context. Each context
has a first page of classes sorted by package first and class name second,
along with a page per package with each classes' constructors, methods, and
fields. A link is generated for each constructor, method, and field to a JavaDoc
page when possible.
ClusterFormationTasks auto configured these properties for clusters.
This PR adds FIPS specific configuration across all test clusters from
the main build script to prevent coupling betwwen testclusters and the
build plugin.
Closes#40904
This change adds either ToXContentObject or ToXContentFragment to classes
directly implementing ToXContent currently. This helps in reasoning about
whether those implementations output full xcontent object or just fragments.

* Same fix as in #38546
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.

* Fix forking JVM runner
* Don't bump shadow plugin version
This moves several test classes that were part of the main root to the test root.
These were part of the main root due to limitations prior to whitelist
customization. Without whitelist customization these can be moved to a test
context and removed from the base whitelists as they should not be user
facing.
Many gradle projects specifically use the -try exclude flag, because
there are many cases where auto-closeable resource ignore is never
referenced in body of corresponding try statement. Suppressing this
warning specifically in each case that it happens using
`@SuppressWarnings("try")` would be very verbose.
This change removes `-try` from any gradle project and adds it to the
build plugin. Also this change removes exclude flags from gradle projects
that is already specified in build plugin (for example -deprecation).

Previously, reindexing from remote using date math in the source index
name did not work if the math contained / or ,. A workaround was to
then URL escape the index name in the request.
With this change, we now support any index name in the remote request
that the remote source supports, doing the URL escape when sending the
request.

To make script_score query to have the same features
as function_score query, we need to add randomScore
function.
This function produces different
random scores on different index shards.
It is also able to produce random scores
based on the internal Lucene Document Ids.
It initially mentioned the type in the exception because the type used to be
required to uniquely identify a document. This is not necessary anymore given
that indices have at most one type.
Adds the search_as_you_type field type that acts like a text field optimized
for as-you-type search completion. It creates a couple subfields that analyze
the indexed terms as shingles, against which full terms are queried, and a
prefix subfield that analyze terms as the largest shingle size used and
edge-ngrams, against which partial terms are queried
Adds a match_bool_prefix query type that creates a boolean clause of a term
query for each term except the last, for which a boolean clause with a prefix
query is created.
The match_bool_prefix query is the recommended way of querying a search as you
type field, which will boil down to term queries for each shingle of the input
text on the appropriate shingle field, and the final (possibly partial) term
as a term query on the prefix field. This field type also supports phrase and
phrase prefix queries however
This commit adds an InboundHandler to handle inbound message processing.
With this commit, this code is moved out of the TcpTransport.
Additionally, finer grained unit tests are added to ensure that the
inbound processing works as expected
Currently there are some components of message serializer and sending
that still occur in TcpTransport. This commit makes it possible to
send a message without the TcpTransport by moving all of the remaining
application logic to the OutboundHandler. Additionally, it adds unit
tests to ensure that this logic works as expected.
This change allows class bindings to add as their first argument, the base script
class. The this reference to the base script class will be implicitly passed into a
class binding as the first constructor argument upon initialization when
specified as the first argument in whitelist entry for the class binding. This
allows a class binding access to additional information added to the base script
class such as more information about the current document or current shard.
One extra requirement for this to work is the appropriate script base class
must be whitelisted (should be empty).
This is the equivalent of the `field_masking_span` query, allowing users to
merge intervals from multiple fields - for example, to search for stemmed tokens
near unstemmed tokens.
Currently, we maintain a transport name ("mock-nio", "nio", "netty")
that is passed to a `TcpTransportChannel` when a request is received.
The value of this name is to associate with the task when we register a
task with the task manager. However, it is only possible to run ES with
one transport, so having an implementation specific name is unnecessary.
This commit removes the name and replaces it with the generic
"transport".
This PR adds an internal REST API for querying context information about
Painless whitelists.
Commands include the following:
GET /_scripts/painless/_context -- retrieves a list of contexts
GET /_scripts/painless/_context?context=%name% retrieves all available
information about the API for this specific context
`document_type` is the type to use for parsing the document to percolate, which
is already optional and deprecated. However `percotale` queries also have the
ability to percolate existing documents, identified by an index, an id and a
type. This change makes the latter optional and deprecated.
Closes#39963
This fixes a bug where a String to char cast in Painless could be done implicitly.
It is now required that a String to char cast is explicit as documented in the
existing specification. This also adds char and Character casting tests.
These simplifications to `MapperMergeValidator` are possible now that there is
always a single mapping definition.
* Remove the type argument in `validateMapperStructure`.
* Remove unnecessary checks against existing mappers.
Prior to this commit (and after 6.5.0), if an ingest node changes
the _index in a pipeline, the original target index would be created.
For daily indexes this could create an extra, empty index per day.
This commit changes the TransportBulkAction to execute the ingest node
pipeline before attempting to create the index. This ensures that the
only index created is the original or one set by the ingest node pipeline.
This was the execution order prior to 6.5.0 (#32786).
The execution order was changed in 6.5 to better support default pipelines.
Specifically the execution order was changed to be able to read the settings
from the index meta data. This commit also includes a change in logic such
that if the target index does not exist when ingest node pipeline runs, it
will now pull the default pipeline (if one exists) from the settings of the
best matched of the index template.

* Optimize Bulk Message Parsing and Message Length Parsing
* findNextMarker took almost 1ms per invocation during the PMC rally track
* Fixed to be about an order of magnitude faster by using Netty's bulk `ByteBuf` search
* It is unnecessary to instantiate an object (the input stream wrapper) and throw it away, just to read the `int` length from the message bytes
* Fixed by adding bulk `int` read to BytesReference
