A persistent action is a transport-like action that is using the cluster state instead of transport to start tasks. This allows persistent tasks to survive restart of executing nodes. A persistent action can be implemented by extending TransportPersistentAction. TransportPersistentAction will start the task by using PersistentActionService, which controls persistent tasks lifecycle. See TestPersistentActionPlugin for an example implementing a persistent action.

This change switches the merge policy to none (for this specific test) in order to make sure that refreshes are always triggered
by a change in the writer.
Closes#27514
This change makes sure that this function does not create field names that end with a '.', more precisely it only allows
alpha-numeric characters to compose the leaf field name.
Closes#27373
The `testMetaPluginPolicyConfirmation` needs to close the file streams it is
iterating over, otherwise some OSes (like Windows) might not be able to delete
all temporary folders, which in turn leads to test failures.
Closes#28415
This commit conditionally adds the --illegal-access=warn flag when tests
are run with java 9. Currently, testing on java 9 triggers a warning
about illegal access from mockito. While that should be fixed (by
updating to a newer mockito base for securemock), the stderr warning we
get is only the first one. Thankfully that is the only one, but this
change will enable finding all such illegal accesses in the future.
Factors the way in which XContent parsing handles deprecated fields
into a callback that is set at parser construction time. The goals here
are:
1. Remove Log4J as a dependency of XContent so that XContent can be used
by clients without forcing log4j and our particular deprecation handling
scheme.
2. Simplify handling of deprecated fields in tests. Now tests can listen
directly for the deprecation callback rather than digging through a
ThreadLocal.
More accurately, this change begins this work. It deprecates a number of
methods, pointing folks to the new versions of those methods that take
`DeprecationHandler`. The plan is to slowly drop these deprecated
methods. Once they are entirely removed we can remove Log4j as
dependency of XContent.
This gives the test longer to block its updates. Now that we're checking
if the updates actually blocked saw that they may not do so in the
normal 10 seconds on a highly loaded system. And our jenkins machines
often function like highly loaded systems. Maybe this fixes#26758!
This change adds support for the new ranking evaluation API to the High Level Rest Client.
This mostly means adding support for parsing the various response objects back from the
REST representation. It includes one change to the response syntax where previously we didn't
print the type of the metric details section but we now need it to pick the right parser to
parse this section back.
Closes#28198
Script fields can get a bit more complicated than just stored fields. A script can return null, an object and also an array. Extended parsing to support such valid values. Also renamed util method from `parseStoredFieldsValue` to `parseFieldsValue` given that it can parse stored fields but also script fields, anything that's returned as `fields`.
Closes#28380
The MockUncasedHostProvider accesses nodes that are not fully built yet, where TransportService.getNode() returns null, which means that the null entries end up in the list of seedNodes that UnicastZenPing then uses.
The test currently makes the assumption that if underlying directory stops throwing exceptions, we can always open the engine. This is not the case as some errors can cause a corruption marker to be placed in the store.
This commit refactors the test to only check that everything is OK if the engine was successfully opened. On top of that, there is no point in checking replay with no errors as we have another test for that.
Closes#28426
This adds the ability to index term prefixes into a hidden subfield, enabling prefix queries to be run without multitermquery rewrites. The subfield reuses the analysis chain of its parent text field, appending an EdgeNGramTokenFilter. It can be configured with minimum and maximum ngram lengths. Query terms with lengths outside this min-max range fall back to using prefix queries against the parent text field.
The mapping looks like this:
"my_text_field" : {
"type" : "text",
"analyzer" : "english",
"index_prefix" : { "min_chars" : 1, "max_chars" : 10 }
}

If a percolator query contains duplicate query clauses somewhere in the query tree then
when these clauses are extracted then they should not affect the msm.
This can lead a percolator query that should be a valid match not become a candidate match,
because at query time, the msm that is being used by the CoveringQuery would never match with
the msm used at index time.
Closes#28315
This commit allows for configuration of the amount of time we wait for a node to startup. This is needed as some QA tests with plugins and tribe timeout when starting the tribe
node. Even regular node startup time with plugins is starting to approach the limit of 30 seconds.
Additionally, this commit provides better feedback when a wait has failed. The code checks to
ensure all expected files exist for each node; if they do not then we consider the wait task as
having failed. Prior to this change, when there was one or more missing file the build would
continue and attempt to execute the wait condition that typically makes an HTTP request to the
cluster. The output of this type of failure does include which files exist and which do not but
this change makes it clearer that the actual HTTP call did not time out, but the failure was before
the call was even made.
Cluster settings shouldn't leak into the next test.
I played with failing the test if it left over any settings but that
felt like it added more ceremony then it was worth. The advantage is
that any test that intentionally wants to leave settings in place after
the test would fail and require looking at but, so far as I can tell, we
don't have any such tests.
This commit switches the internal format of the elasticsearch keystore
to no longer use java's KeyStore class, but instead encrypt the binary
data of the secrets using AES-GCM. The cipher key is generated using
PBKDF2WithHmacSHA512. Tests are also added for backcompat reading the v1
and v2 formats.
Currently meta plugins will ask for confirmation of security policy
exceptions for each bundled plugin. This commit collects the necessary
permissions of each bundled plugin, and asks for confirmation of all of
them at the same time.
In some cases testShrinkIndexPrimaryTerm creates then 'mutates' 210
shards. If each shard opens more than 10 files (translog, lucene index),
we exceeded the maximum allowed file handles. In our test, the number of
file handles is limited to 2048 by HandleLimitFS. This commit reduces
the number of shards in testShrinkIndexPrimaryTerm to avoid such errors.
Closes#28153
Clear the disk watermark after the snippet showing users how to set it.
Without this our tests will fail if the disks have less than 10GB free.
Closes#28325
Prints the warning level logs from the integration testing cluster if
there is a failure. We'd attempted to print those logs but I believe our
regex was missing a space.
In rare cases the total nanoseconds for an entire window of operations can be 0
nanoseconds, causing the assertion in
QueueResizingEsThreadPoolExecutor.calculateLambda to trip. This ensures that we
calculate the lambda value with at least 1 nanosecond.
Resolves#27607
This pull request replaces the jvm-example plugin (from the jvm/site plugins era) by two new plugins: a custom-settings that shows how to register and use custom settings (including secured settings) in a plugin, and rest-handler plugin that shows how to register a rest handler.
The two plugins now reside in the plugins/examples project. They can serve as sample plugins for users, a special attention has been put on documentation. The packaging tests have been adapted to use the custom-settings plugin.
Our rest client throws exceptions in funny ways that might cause
`suppressed` exceptions to be eaten. This works around that in the
reindex-from-old tests so we don't stomp on a real failure. It is fairly
diryt so we should work on fixing the high level rest client.

The implementation maintains the order of the original requests yet this
functionality is not documented. This commit adds a note to the docs
regarding the ordering of responses to an multi-get request.

Currently this method parses the string as a double. This means that it
might lose accuracy if the value is a long that is greater than
2^52. This commit changes this method to try to detect whether the
string represents a long first.
This commit updates netty to 4.1.16.Final. This is the latest version that we can have work without
extra permissions. This updated version of netty fixes issues seen with Java 9 and some data
not being sent, which results in timeouts.
Today after writing an operation to an engine, we will call
`IndexShard#afterWriteOperation` to flush a new commit if needed. The
`shouldFlush` condition is purely based on the uncommitted translog size
and the translog flush threshold size setting. However this can cause a
replica execute an infinite loop of flushing in the following situation.
1. Primary has a fully baked index commit with its local checkpoint
equals to max_seqno
2. Primary sends that fully baked commit, then replays all retained
translog operations to the replica
3. No operations are added to Lucence on the replica as seqno of these
operations are at most the local checkpoint
4. Once translog operations are replayed, the target calls
`IndexShard#afterWriteOperation` to flush. If the total size of the
replaying operations exceeds the flush threshold size, this call will
`Engine#flush`. However the engine won't flush as its index writer does
not have any uncommitted operations. The method
`IndexShard#afterWriteOperation` will keep flushing as the condition
`shouldFlush` is still true.
This issue can be avoided if we always flush if the `shouldFlush`
condition is true.
It has been pointed out that GET with body may cause problems to some proxies. We are then switching to POST the API that retrieve info and support a request body.
