Before this change the processing of the ranges in the date range (and
other range type) aggregations was done when the Aggregator was created.
This meant that the SearchContext did not know that now had been used in
a range until after the decision to cache was made.
This change moves the processing of the ranges to the aggregation builders
so that the search context is made aware that now has been used before
it decides if the request should be cached
This commit adds a did you mean feature to the strict REST params error
message. This works by comparing any unconsumed parameters to all of the
consumer parameters, comparing the Levenstein distance between those
parameters, and taking any consumed parameters that are close to an
unconsumed parameter as candiates for the did you mean.
* Fix pluralization in strict REST params message
This commit fixes the pluralization in the strict REST parameters error
message so that the word "parameter" is not unconditionally written as
"parameters" even when there is only one unrecognized parameter.
* Strength strict REST params did you mean test
This commit adds an unconsumed parameter that is too far from every
consumed parameter to have any candidate suggestions.

This commit changes the strict REST parameters message to say that
unconsumed parameters are unrecognized rather than unused. Additionally,
the test is beefed up to include two unused parameters.

Today when parsing a request, Elasticsearch silently ignores incorrect
(including parameters with typos) or unused parameters. This is bad as
it leads to requests having unintended behavior (e.g., if a user hits
the _analyze API and misspell the "tokenizer" then Elasticsearch will
just use the standard analyzer, completely against intentions).
This commit removes lenient URL parameter parsing. The strategy is
simple: when a request is handled and a parameter is touched, we mark it
as such. Before the request is actually executed, we check to ensure
that all parameters have been consumed. If there are remaining
parameters yet to be consumed, we fail the request with a list of the
unconsumed parameters. An exception has to be made for parameters that
format the response (as opposed to controlling the request); for this
case, handlers are able to provide a list of parameters that should be
excluded from tripping the unconsumed parameters check because those
parameters will be used in formatting the response.
Additionally, some inconsistencies between the parameters in the code
and in the docs are corrected.

On Windows the JDK uses `CreateFileW` which has a stupidly high
limit for the number of `Handle`s it can make - `16 * 1024 * 1024`.
So this isn't really a problem on Windows at all.
Closes#20732
Today, the individual allocation deciders appear in random
order when initialized in AllocationDeciders, which means
potentially more performance intensive allocation deciders
could run before less expensive deciders. This adds to the
execution time when a less expensive decider could terminate
the decision making process early with a NO decision. This
commit orders the initialization of allocation deciders,
based on a general assessment of the big O runtime of each
decider, moving the likely more expensive deciders last.
Closes#12815
IndicesClusterStateService and IndicesStore are responsible for synchronizing local shard state based on incoming cluster state updates. On client/tribe nodes, which don't store any such shard/index data/metadata, all of the logic that computes which data is to be deleted, which shards to be initialized etc. can be completely skipped, saving precious CPU cycles.
CompositeIndicesRequest should be implemented by all requests that are composed of multiple subrequests which relate to one or more indices. A composite request is
executed by its own transport action class (e.g. TransportMultiSearchAction for _msearch), which goes through all the subrequests and delegates their execution to the appropriate transport action (e.g. TransportSearchAction for _msearch) for each single item. IndicesAliasesRequest is a particular request as it holds multiple items that implement AliasesRequest, but it shouldn't be considered a composite request, as it has no specific transport action for each of its items. Also, either all of its subitems fail or succeed.
Also clarified javadocs for CompositeIndicesRequest.
We have new icons for elastic products with 5.0. This change updates the
favicon embedded in elasticsearch that users see when using the rest api
through a browser.
When a node get disconnected from the cluster and rejoins during a master election, it may be that the new master already has that node in it's cluster and will try to assign it shards. If the node hosts started primaries, the new shards will be initializing and will have the same allocation id as the allocation ids of the current started size. We currently do not recognize this currently. We should clean the current IndexShard instances and initialize new ones.
This also hardens test assertions in the same area.
This makes geo-distance sorting use `LatLonDocValuesField.newDistanceSort`
whenever applicable, which should be faster that the current approach since it
tracks a bounding box that documents need to be in in order to be competitive
instead of doing a costly distance computation all the time.
Closes#20450
today it's not possible to use date-math efficiently with the `_rollover`
API. This change adds support for date-math in the target index as well as
support for preserving the math logic when an existing index that was created with
a date math expression all subsequent indices are created with the same expression.
Right now our unit tests in that area only simulate indexing single documents. As we go forward it should be easy
to add other actions, like delete & bulk indexing. This commit extracts the common parts of the current indexing
logic to a based class make it easier to extend.
The Setting.timeValue() method uses TimeValue.toString() which can produce fractional time values. These fractional time values cannot be parsed again by the settings framework.
This commit fix a method that still use the .toString() method and replaces it with .getStringRep(). It also changes a second method so that it's not up to the caller to decide which stringify method to call.

This commit fixes a failing cluster settings tests, namely the logger
level update test. The test was incorrectly assuming the default log
level was info, but it could be non-info, for example, if
tests.es.logger.level is set to some non-info level.
Closes#20318
The logging listener tests started failing after
953a8a959b when the tests are run with
tests.es.logger.level set to any level other than debug. This is because
these tests were based around the assumption that the default logging
level was info, which was the case before that commit fixed setting the
default logging level via that system property. This commit fixes these
failing tests by adjusting this assumption to account for the fact that
the default logging level could be different.
Today we allow system bootstrap checks to be ignored with a
setting. Yet, the system bootstrap checks are as vital to the health of
a production node as the non-system checks (e.g., the original bootstrap
check, the file descriptor check, is critical for reducing the chances
of data loss from being too low). This commit removes the ability to
ignore system bootstrap checks.
