This can be used to restrict the amount of CPU a single
structure finder request can use.
The timeout is not implemented precisely, so requests
may run for slightly longer than the timeout before
aborting.
The default is 25 seconds, which is a little below
Kibana's default timeout of 30 seconds for calls to
Elasticsearch APIs.
When a script uses the special-cased SearchScript or ExecutableScript, Painless is
internally caching the GenericElasticsearchScript that is generated via compile as part of
the newInstance method for the factories. This breaks the model for class bindings as the
class binding expects to not have any stored information for each instance generated via
newInstance from the factory. This change fixes the issue by creating a new instance of
the GenericElasticsearchScript each time newInstance is called against the factory.
Prior to following an index in the follow API, check whether current
user has sufficient privileges in the leader cluster to read and
monitor the leader index.
Also check this in the create and follow API prior to creating the
follow index.
Also introduced READ_CCR cluster privilege that include the minimal
cluster level actions that are required for ccr in the leader cluster.
So a user can follow indices in a cluster, but not use the ccr admin APIs.

In prior versions of Java, we expected to see a SSLHandshakeException
when starting a handshake with a server that we do not trust. In JDK11,
the exception has changed to a SSLException, which
SSLHandshakeException extends. This is most likely a side effect of the
TLS 1.3 changes in JDK11. This change updates the test to catch the
SSLException instead of the SSLHandshakeException and enables the test
to work on JDK8 through JDK11.
Closes#29989
The SSLService invalidates SSLSessions when there is a change to any of
the underlying key or trust material. However, this invalidation code
did not check for a null SSLSession being returned from the context and
assumed that the context would always return a non-null object. The
return of a null object is possible in all versions, but JDK11 seems to
return them more often due to changes for TLS 1.3. There are a number
of reasons that we get a id of a session but the context returns null
when the session with that id is requested. Some of the reasons for
this are:
* Session was evicted by session cache
* Session has timed out
* Session has been invalidated by another caller
To handle this, the SSLService now checks if the value is null before
calling invalidate on the SSLSession.
Closes#32124
This commit removes the use of ExecutableScript from watcher in favor of
custom script contexts for both watcher condition scripts and transform
scripts.

We are using a deprecated method for checking if an S3 bucket
exists. This deprecated method has a limitation that it can not
distinguish between invalid credentials and a lack of permissions. This
commit switches to using a method that correctly surfaces if invalid
credentials are supplied when checking for the existence of a bucket.
Introduces `RestClientBuilder#setStrictDeprecationMode` which defaults
to false but when set to true, causes a rest request to fail if a
deprecation warning header comes back in the response from Elasticsearch.
This should be valueable to Elasticsearch's tests, especially those of the
High Level REST Client where they will help catch divergence between the
client and the server.
The following changes were made:
* Added ElasticsearchSecurityException. For in the case the current user has insufficient privileges while an index is being followed. Prior to following ccr checks whether the current user has sufficient privileges and if not the follow api fails with an error.
* Added Index block exception. If the leader index gets closed, this exception is returned.
* Added ClusterBlockException service unavailable. In case for example the leader cluster is without elected master.
* Removed IndexNotFoundException. If the leader / follower index has been deleted, ccr will need to stop the shard follow tasks with an error.
Closes#33954
Fixes the equals and hash function to ignore the order of aggregations to ensure equality after serialization
and deserialization. This ensures storing configs with aggregation works properly.
This also addresses a potential issue in caching when the same query contains aggregations but in
different order. 1st it will not hit in the cache, 2nd cache objects which shall be equal might end up twice in
the cache.
In order to be compatible with joda time, this adds an epoch seconds
formatter, that is able to parse floating point values.
However joda time discards the floating point values, but still parses
the data, where as this one is able to parse the whole value including
milliseconds.
Due to a bug, that was fixed in #33360 and commit
1de2a925ce the initial adding of a watch
could get lost, thus leaving the watcher stats count as zero despite adding a watch.
Closes#33326
The synonym filters no longer need access to the AnalysisRegistry in their
constructors, so we can remove the special-case code and move them to the
common analysis module.
This commit means that synonyms are no longer available for `server` integration tests,
so several of these are either rewritten or migrated to the common analysis module
as rest-spec-api tests
* Renamed CCR APIs
Renamed:
* `/{index}/_ccr/create_and_follow` to `/{index}/_ccr/follow`
* `/{index}/_ccr/unfollow` to `/{index}/_ccr/pause_follow`
* `/{index}/_ccr/follow` to `/{index}/_ccr/resume_follow`
Relates to #33931
always use `IndicesOptions.strictExpand()` for indices options.
The follow index may be closed and we still want to get stats from
shard follow task and the whether the provided index name matches with
follow index name is checked when locating the task itself in the ccr
stats transport action.
* Make sure 'ignored' and 'routing' field types inherit from StringFieldType.
* Add tests for prefix and regexp queries.
* Support prefix and regexp queries on _index fields.
`Settings` is no longer required to get a `Logger` and we went to quite
a bit of effort to pass it to the `Logger` getters. This removes the
`Settings` from all of the logger fetches in security and x-pack:core.
Centralize and simplify the script generation between operators and functions which are currently decoupled. As part of this process most predicates (<, <=, etc...) were made ScalarFunction as their purpose and functionality is quite similar (see % and MOD functions).
Renamed ProcessDefinition to Pipe
Add ScriptWeaver as a mixin-in interface for script customization
Add logic for equals/lte/lt
Improve BinaryOperator/expression toString
Minimize duplication across string functions
Close#33975
This commit adds the ability to plug in compilation of custom contexts
in mock script engine. This is needed for testing plugins which add
custom contexts like watcher.
Prior to this change when a pipeline processor called another
pipeline, only the stats for the first processor were recorded.
The stats for the subsequent pipelines were ignored. This change
properly accounts for pipelines irregardless if they are the first
or subsequently called pipelines.
This change moves the state of the stats from the IngestService
to the pipeline itself. Cluster updates are safe since the pipelines
map is atomically swapped, and if a cluster update happens
while iterating over stats (now read directly from the pipeline)
a slightly stale view of stats may be shown.
Recently we introduced the settings cluster.remote to take the place of
search.remote for configuring remote cluster connections. We made this
change due to the fact that we have generalized the remote cluster
infrastructure to also be used within cross-cluster replication and not
only cross-cluster search. For backwards compatibility, when we made this
change, we allowed that cluster.remote would fallback to
search.remote. Alas, the initial change for this contained a bug for
handling the proxy and seeds settings. The bug for the seeds settings
arose because we were manually iterating over the concrete settings only
for cluster.remote seeds but not for search.remote seeds. This commit
addresses this by iterating over both cluster.remote seeds and
search.remote seeds. Additionally, when checking for existence of proxy
settings, we have to not only check cluster.remote proxy settings, but
also fallback to search.remote proxy settings. This commit addresses
both issues, and adds tests for these situations.
Now that all basic APIs for managing jobs and datafeeds have been
implemented we replace the duplicated `MlRestTestStateCleaner`
with an implementation that uses the HLRC Machine Learning client
itself.
* Handle MatchNoDocsQuery in span query wrappers
This change adds a new SpanMatchNoDocsQuery query that replaces
MatchNoDocsQuery in the span query wrappers.
The `wildcard` query now returns MatchNoDocsQuery if the target field is not
in the mapping (#34093) so we need the equivalent span query in order to
be able to pass it to other span wrappers.
Closes#34105
Currently a bad regex in CORS settings throws a PatternSyntaxException, which
then bubbles up through the bootstrap code, meaning users have to parse a
stack trace to work out where the problem is. We should instead catch this
exception and rethrow with a more useful error message.
This commit adds support for role mapping expression dsl.
Functionally it is similar to what we have on the server side
except for the rule evaluation which is not required on the client.
The role mapper expression can either be field expression or
composite expression of one or more expressions. Role mapper
expression parser is used to parse JSON DSL to list of expressions.
This forms the base for role mapping APIs (get, post/put and delete)
Watcher is using a lot of so called TextTemplate fields in a watch
definition, which can use mustache to insert the watch id for example.
For the user it is non-obvious which field is just a string field or
which field is a text template.
This also means, that for every such field, we currently do a script
compilation, even if the field does not contain any mustache syntax.
This will lead to an increased script cache churn, because those
compiled scripts (that only contain a string), will evict other scripts.
On top of that, this also means that an unneeded compilation has
happened, instead of returning that string immediately.
The usages of mustache templating are in all of the actions (most of the time far
more than one compilation) as well as most of the inputs.
Especially when running a lot of watches in parallel, this will reduce
execution times and help reuse of real scripts.
EngineSearcher can be easily folded into Engine.Searcher which removes
a level of inheritance that is necessary for most of it's subclasses.
This change folds it into Engine.Searcher and removes the dependency on
ReferenceManager.
* This should surface what errors are thrown on CI
and in org.elasticsearch.transport.RemoteClusterConnection.ConnectHandler#collectRemoteNodes
(the sequence of caught error in the last catch block and moving on to the next seed node
seems to be the only path by which the errors logged in #33756 could come about)
* Relates #33756
This commit adds "engine is closed" as an expected failure message.
This change is due to #33967 in which we might access a closed engine on
promotion.
Relates #33967
This change is related to #33903 that ports the DocStats
simplification to the master branch. This change builds the docStats
in the ReadOnlyEngine from the last committed segment infos rather than
the reader.
