Constructing the timout checker FIRST and THEN registering the watcher allows the test to have a race condition.
The timeout value could be reached BEFORE the matcher is added. To prevent the matcher never being interrupted, a new timedOut value is added to the watcher thread entry. Then when a new matcher is registered, if the thread was previously timedout, we interrupt the matcher immediately.
closes#48861
We were checking for loops in queries before, but we had an "off by one"
error where we wouldn't notice the "top level" runtime field when
detecting a loop. So the error message would be wrong.
I also caught a few bugs with query generation caused by missing
`@Override` annotations and fixed a few of them. There is a bug with
`regexp` queries with match options that I'm not fixing in this PR but
will get to later.

This commit unmutes the windows check for testTooManyPartitions test.
The assertion has since changed to include a soft_limit check.
This coupled with changes over the past years means the test should be enabled again.

With the addition of sub aggregations like filter, the validation could fail if 2 sub aggs use the
same output name. This change makes validation sub-agg aware.
fixes#57814
The OpenID Connect specification defines a number of ways for a
client (RP) to authenticate itself to the OP when accessing the
Token Endpoint. We currently only support `client_secret_basic`.
This change introduces support for 2 additional authentication
methods, namely `client_secret_post` (where the client credentials
are passed in the body of the POST request to the OP) and
`client_secret_jwt` where the client constructs a JWT and signs
it using the the client secret as a key.
Support for the above, and especially `client_secret_jwt` in our
integration tests meant that the OP we use ( Connect2id server )
should be able to validate the JWT that we send it from the RP.
Since we run the OP in docker and it listens on an ephemeral port
we would have no way of knowing the port so that we can configure
the ES running via the testcluster to know the "correct" Token
Endpoint, and even if we did, this would not be the Token Endpoint
URL that the OP would think it listens on. To alleviate this, we
run an ES single node cluster in docker, alongside the OP so that
we can configured it with the correct hostname and port within
the docker network.

This implements the `fields` API in `_search` for runtime fields using
doc values. Most of that implementation is stolen from the
`docvalue_fields` fetch sub-phase, just moved into the same API that the
`fields` API uses. At this point the `docvalue_fields` fetch phase looks
like a special case of the `fields` API.
While I was at it I moved the "which doc values sub-implementation
should I use for fetching?" question from a bunch of `instanceof`s to a
method on `LeafFieldData` so we can be much more flexible with what is
returned and we're not forced to extend certain classes just to make the
fetch phase happy.

This speeds up `StreamOutput#writeVInt` quite a bit which is nice
because it is *very* commonly called when serializing aggregations. Well,
when serializing anything. All "collections" serialize their size as a
vint. Anyway, I was examining the serialization speeds of `StringTerms`
and this saves about 30% of the write time for that. I expect it'll be
useful other places.
Prevent the analyzer for trying to resolve aliases on expressions that
reference themselves (or fields within themselves) as that causes
infinite recursion.

This adds two extra bits of info to the profiler:
1. Count of the number of different types of collectors. This lets us figure
out if we're using the optimization for segment ordinals. It adds a few
more similar counters just for good measure.
2. Profiles the `getLeafCollector` and `postCollection` methods. These are
non-trivial for some aggregations, like cardinality.
We want Logstash indices to be system indices, but the logstash
service will still need to be able to manage its indices. This PR
adds special system index APIs to the logstash plugin so that
logstash can manage its pipelines without direct access to the
underlying indices.
* Add logstash module with dedicated logstash APIs
* merge with x-pack plugin
* add system index access allowance
* Break out serialization tests into distinct classes
* Log failures for partial multiget failure
* Move LogstashSystemIndexIT to javaRestTest task

We never see this exception in the logs even though it's pretty severe.
All we might see is an exception about a transport message not having been read fully
from the logic that follows this code.
Technically we should probably bubble up the exception but that's a bigger change
and needs some carefully reasoning, this change for the time being at least simplifies
tracking down deserialization issues in responses.
FastVectorHighlighter uses the top-level reader to rewrite queries against, which
it gets via an IndexSearcher field on HitContext. However, we can already access
this top-level reader via HitContext's existing LeafReaderContext field.
This commit removes the unnecessary field and constructor parameter, and
changes the implementation of topLevelReader to go via ReaderUtils and
the leaf reader context.
AuthorizationService#authorize uses the thread context to carry the result of the
authorisation as transient headers. The listener argument to the `authorize` method
must necessarily observe the header values. This PR makes it so that
the authorisation transient headers (`_indices_permissions` and `_authz_info`, but
NOT `_originating_action_name`) of the child action override the ones of the parent action.

This was missing and caused nodes to drop out of the cluster on serialization failures
when ever one tried to get an enrich policy task by name.
The test in here is a little dirty but I figured it would be nice to have an actual reproducer
for the issue and I couldn't find any infrastructure to nicely time the tasks so I put this on
top of existing test infra.
Use the newly introduced PIT API to have a consistent view of the data
while doing sequence matching, which involves multiple calls, aka
repeatable reads and thus avoid race conditions or any in-flight updates
on the data.

Today when an S3RetryingInputStream is closed the remaining bytes
that were not consumed are drained right before closing the underlying
stream. In some contexts it might be more efficient to not consume the
remaining bytes and just drop the connection.
This is for example the case with snapshot backed indices prewarming,
where there is not point in reading potentially large blobs if we know
the cache file we want to write the content of the blob as already been
evicted. Draining all bytes here takes a slot in the prewarming thread
pool for nothing.
This change adds an aggregation that can be used to delay the
query phase execution on shards with a configurable time:
{
"aggs": {
"delay": {
"shard_delay": {
"value": "30s"
},
"aggs": {
"host": {
"terms": {
"field": "hostname"
}
}
}
}
}
}
This test module is built on top of #61954 so the aggregation will be available only within
snapshots since this module is not meant to be used in production.
Closes#54159

There is a race in this test where the index request will return
once the dynamic mapping update has been observed by the cluster
state observer internally used by the indexing but not hit all
state appliers and thus isn't showing up as the applied state returned
by `clusterService.state()` yet.
We have a special FetchPhaseExecutionException which contains some useful
information about which shard and doc a fetch phase has failed in. However, this
is not used in many places - currently only the ExplainPhase and the highlighters
throw one, and the FetchPhase itself catches IOExceptions and just passes them
to the ExceptionsHelper with no extra context.
This commit changes FetchPhase to throw FetchPhaseExecutionException if it
encounters problems in any of its subphases, and removes the special handling
from the explain and highlight phases. It also removes the need to pass shard ids
around when building HitContext objects.
The log4j config in :qa:os was broken because it referenced an appender plugin that is not
on that project's classpath. Resolve this by adding a dedicated logging config and removing
the copy step.
The complexity of removing a timeout listener was `O(n)` which
means that in case of many queued up CS update tasks (such as in the
case of an avalanche of dynamic mapping updates) we're dealing with
quadratic complexity for timing out N tasks which was observed to be
an issue in practice.
This PR makes the complexity of timing out a task `O(1)` and generally
simplifies the iteration logic of listeners and applies to be a little
more efficient and inline better.
* Add "synthetics-*-*" templates for synthetics fleet data
For the Elastic Agent we currently have `logs` and `metrics`, however, synthetic data doesn't belong
with those and thus we should have a place for it to live. This would be data reported from
heartbeat and under the 'monitoring' category.
This commit adds a composable index template for `synthetics-*-*` indices similar to the work in
#56709 and #57629.
Resolves#61665
The case InnerHitBuilderTests#testEqualsAndHashcode creates a copy of the object
by serializing + deserializing it, then applies a modification. If the 'fields'
list is empty, then deserializing it results in Collections.emptyList. Because
this is immutable, then modifying it can throw an UnsupportedOperationException.
This PR takes the same approach as for docvalue_fields, where we create a new
list instead of trying to add to an empty one.
This PR adds support for the 'fields' option in the following places:
* Anytime `inner_hits` is used, for both fetching nested/ child docs and field collapsing
* The `top_hits` aggregation
Addresses #61949.
The annotations index is not covered by the comparison between
mappings and templates, as it does not use an index template.
This commit adds an assertion on annotations index mappings
that will fail if the mappings are not upgraded as expected.
Backport of #62325
Followup to #61681:
- reuse the current iterator in `reset()` if possible
- simply some integer-overflow-avoidance in `skip()`
- clarify some comments
- address some IntelliJ warnings
The job comms thread pool is intended for the long-running job
processes that do anomaly detection or data frame analytics and
count towards job count and memory limits.
This commit moves the short-lived memory estimation processes
to the ML utility thread pool.
Although this doesn't matter in most cases, at the limits of
scale it could mean that memory estimations would get in the way
of starting jobs, or would queue up for an excessive period of
time while waiting for jobs to finish.
