We use wrap code in `// tag` and `//end` to include it in our docs. Our
current docs style wraps code snippets in a box that is only wide enough
for 76 characters and adds a horizontal scroll bar for wider snippets
which makes the snippet much harder to read. This adds a checkstyle check
that looks for java code that is included in the docs and is wider than
that 76 characters so all snippets fit into the box. It solves many of
the failures that this catches but suppresses many more. I will clean
those up in a follow up change.
This commit adds a check for "enabled" attribute change for types when
a RestPutMappingAction is received. A MappingException is thrown when
such a change is detected. Change are prevented in both ways: "false -> true"
and "true -> false".
Closes#33566
Since #34099, the FollowingEngine will skip an operation which was
already processed before. With that change, it should be okay to unmute
testFollowIndexAndCloseNode.
This change fixes a potential deadlock problem in the unit
test introduced in #34117.
It also removes a piece of debug code and corrects a docs
formatting problem that were both added in that same PR.
#32281 adds elasticsearch-shard to provide bwc version of elasticsearch-translog for 6.x; have to remove elasticsearch-translog for 7.0
Relates to #31389
This arose when two commits were pushed at roughly the same time, both
of which compiled successfully against master, but not when taken
together. This commit fixes a reference in one of the commits that was
changed in the other commit.
This commit modifies the CCR stats endpoint for indices to be
/{index}/_ccr/stats. This makes this endpoint consistent with other
index-centric endpoints like indices stats.
The unfollow API changes a follower index into a regular index, so that it will accept write requests from clients.
For the unfollow api to work the index follow needs to be stopped and the index needs to be closed.
Closes#33931
This change introduces the indexing optimization using sequence numbers
in the FollowingEngine. This optimization uses the max_seq_no_updates
which is tracked on the primary of the leader and replicated to replicas
and followers.
Relates #33656
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.
Closes#33553

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.
