that have analyzer aliases in their analysis settings will still work, but
any attempts to create an alias for analyzers in newly created indices
will result in an IllegalArgumentException.
As a result, the setting `index.analysis.analyzer.{analyzerName}.alias` is
no longer supported.
Closes#18244
The term persisted task was used to indicate that a task should store its results upon its completion. We would like to use this term to indicate that a task can survive restart of nodes instead. This commit removes usages of the term "persist" when it means store results.
This commit fixes the number of max local storage nodes setting used in
the discovery disruption tests. In some cases (randomly but rarely), the
acked indexing test can run with five nodes instead of three, breaching
the max local storage nodes configuration.
As the most complicated `FetchSubPhase` highlighting gets its own package
(`o.e.seach.fetch.subphase.highlight`. No other `FetchSubPhase`s get their
own package. Instead they all reside together in `o.e.search.fetch.subphase`.
Add package descriptions to `o.e.search.fetch` and subpackages.
This commit adds a function to shard-level query result to determine whether
there are any hits that needs fetching. Currently, a shard-level query result
can have hits when there are search hits and/or completion suggestion hits.
The newly added function encapsulates the checks to determine if a shard-level
query result has any fetchable hits, which is used in optimizing for sorting
documents and releasing search request contexts.
We have 1074 snippets that look like they should be converted to
`// CONSOLE`. At least that is what `gradle docs:listConsoleCandidates`
says. This adds `// NOTCONSOLE` to explicitly mark snippets that
*shouldn't* be converted to `// CONSOLE`. After marking the blindingly
obvious ones this cuts the remaining snippet count to 1032.
Previously, we only caught subclasses of Exception, however, there are
some cases when Errors are thrown instead of Exceptions. These two cases
are `assert` and when a class cannot be found.
Without this change, the exception would bubble up to the
`uncaughtExceptionHandler`, which would in turn, exit the JVM
(related: #19923).
A note of difference between regular Java asserts and Groovy asserts,
from http://docs.groovy-lang.org/docs/latest/html/documentation/core-testing-guide.html
"Another important difference from Java is that in Groovy assertions are
enabled by default. It has been a language design decision to remove the
possibility to deactivate assertions."
In the event that a user uses an assert such as:
```groovy
def bar=false; assert bar, "message";
```
The GroovyScriptEngineService throws a NoClassDefFoundError being unable
to find the `java.lang.StringBuffer` class. It is *highly* recommended
that any Groovy scripting user switch to using regular exceptions rather
than unconfiguration Groovy assertions.
Resolves#19806
If a primary fails, an active replica is promoted to primary. Once we do the promotion, however, we are sure that the active replica is not relocating anymore. The reason is that when the primary fails, we first remove/cancel all initializing replicas (also if they are relocation targets). This is the only safe thing to do anyhow, because promoting relocating replica to primary would also mean that the replica recovery of the replica relocation target is suddenly promoted to primary relocation, which the recovery code treats in a different way.
This commit defaults the max local storage nodes to one. The motivation
for this change is that a default value greather than one is dangerous
as users sometimes end up unknowingly starting a second node and start
thinking that they have encountered data loss.

ContextIndexSearcher#explain ignores the dfs data to create the normalized weight.
This change fixes this discrepancy by using the dfs data to create the normalized weight when needed.
Update by query is a shortcut to search + index. UpdateByQueryRequest gets serialized on the transport layer only when the transport client is used. Given that the request supports wildcards and allows to set its indices, it should implement IndicesRequest.Repleaceable. implementing CompositeIndicesRequest makes little sense as the indices that the request works against depend entirely on the inner search request.
Delete by query is a shortcut to search + delete. DeleteByQueryRequest gets serialized on the transport layer only when the transport client is used. Given that the request supports wildcards and allows to set its indices, it should implement IndicesRequest.Repleaceable
This commit fixes the handling of spaces in the path to the jvm.options
file on Windows. The issue is that the extraneous set of quotes were
included as part of the value of ES_JVM_OPTIONS thus confusing further
downstream commands.

Fixes two issues:
1. lang-javascript doesn't support `executable` with a `null` `vars`
parameters. The parameter is quite nullable.
2. reindex didn't support script engines who's `unwrap` method wasn't
a noop. This didn't come up for lang-groovy or lang-painless because
both of those `unwrap`s were noops. lang-javascript copys all maps that
it `unwrap`s.
This adds fairly low level unit tests for these fixes but dosen't add
an integration test that makes sure that reindex and lang-javascript
play well together. That'd make backporting this difficult and would
add a fairly significant amount of time to the build for a fairly rare
interaction. Hopefully the unit tests will be enough.
This commit separates the description of the links in the network that are to be disrupted from the failure that is to be applied to the links (disconnect/unresponsive/delay). Previously we had subclasses for the various kind of network disruption schemes combining on one hand failure mode (disconnect/unresponsive/delay) as well as the network links to cut (two partitions / bridge partitioning) into a single class.
Reducing the ping timeouts on a test that does not simulate network failures can cause node disconnects within the test on a slow CI machine.
The test testSearchWithRelocationAndSlowClusterStateProcessing does not expect such disconnects, leading to shard relocation in the test to abort prematurely.
Today in the uncaught exception handler, we attempt to halt the virtual
machine on fatal errors. Yet, halting the virtual machine requires
privileges which might not be granted to the caller when the exception
is thrown for example from a scripting engine. This means that if an
OutOfMemoryError or another fatal error is hit inside a script, the
virtual machine will not exit because the halt call will be denied for
securiry privileges. In this commit, we mark this halt call as trusted
so that the virtual machine can be halted if a fatal error is
encountered in a script.
