As per #45852 comment we no longer need to log stack-traces in
SecurityTransportExceptionHandler and SecurityHttpExceptionHandler even
if trace logging is enabled.

The test seems to have been failing due to a race condition between
stopping the task and refreshing the destination index. In particular,
we were going forward with refreshing the destination index even
though the task stopped in the meantime. This was fixed in
request.

Previously, when the condition (1st argument) of the IIF function could
be evaluated (folded) to false, the `IfConditional` was eliminated which
caused `IndexOutOfBoundsException` to be thrown when `info()` and
`resolveType()` methods where called.

If a primary as being relocated, then the global checkpoint and
retention lease background sync can emit unnecessary warning logs.
This side effect was introduced in #42241.

We hit a bug where we can't partially update documents created in a
mixed cluster between 5.x and 6.x. Although this bug does not affect
7.0 or later, we should have a good test that catches this issue.

When a shard has fallen search idle, and a non-realtime multi-get
request is executed, today such requests do not wait for the shard to
become search active and therefore such requests do not wait for a
refresh to see the latest changes to the index. This also prevents such
requests from triggering the shard as non-search idle, influencing the
behavior of scheduled refreshes. This commit addresses this by attaching
a listener to the shard search active state for multi-get requests. In
this way, when the next scheduled refresh is executed, the multi-get
request will then proceed.

testSyncFailsIfOperationIsInFlight could fail due to the index request
spawing a GCP sync (new since 7.4). Test now waits for it to finish
before testing that flushed sync fails.
Fixes a problem where operations_behind would be one less than
expected per shard in a new index matched by the data frame
transform source pattern.
For example, if a data frame transform had a source of foo*
and a new index foo-new was created with 2 shards and 7 documents
indexed in it then operations_behind would be 5 prior to this
change.
The problem was that an empty index has a global checkpoint
number of -1 and the sequence number of the first document that
is indexed into an index is 0, not 1. This doesn't matter for
indices included in both the last and next checkpoints, as the
off-by-one errors cancelled, but for a new index it affected
the observed result.
With this change, we can avoid blocking writing threads when trimming
unreferenced readers; hence improving the translog writing performance
in async durability mode.

* Wait for all Rec. to Stop on Node Close
* This issue is in the `RecoverySourceHandler#acquireStore`. If we submit the store release to the generic threadpool while it is getting shut down we never complete the futue we wait on (in the generic pool as well) and fail to ever release the store potentially.
* Fixed by waiting for all recoveries to end on node close so that we aways have a healthy thread pool here
* Closes#45956
When some high values are randomly picked up - for example the number
of indices to snapshot or the number of snapshots to create - the tests
in S3BlobStoreRepositoryTests can generate a high number of requests to
the internal S3 server.
In order to test the retry logic of the S3 client, the internal server is
designed to randomly generate random server errors. When many
requests are made, it is possible that the S3 client reaches its maximum
number of successive retries capacity. Then the S3 client will stop
retrying requests until enough retry attempts succeed, but it means
that any request could fail before reaching the max retries count and
make the test fail too.

Fix test issue to stabilise scoring through use of DFS search mode.
Randomised index-then-delete docs introduced by the test framework likely caused an imbalance in IDF scores across shards. Also made number of shards used in test a random number for added test coverage.

Previously, if the DataType of all the WHEN conditions of a CASE
statement is NULL, then it was set to NULL even if the ELSE clause
has a non-NULL data type, e.g.:
```
CASE WHEN a = 1 THEN NULL
WHEN a = 5 THEN NULL
ELSE 'foo'
```

This is the first PR that merges changes made to server module from
the enrich branch (see #32789) into the master branch.
The plan is to merge changes made to the server module separately from
the pr that will merge enrich into master, so that these changes can
be reviewed in isolation.
Some netty behavior is controlled by system properties. While we want to
test with the defaults for Elasticsearch for most tests, within netty we
want to ensure these netty settings exhibit correct behavior. This
commit adds variants of test and integTest tasks for netty which set the
unpooled and direct buffer pooled allocators.

Though we allow CCS within datafeeds, users could prevent nodes from accessing remote clusters. This can cause mysterious errors and difficult to troubleshoot.
This commit adds a check to verify that `cluster.remote.connect` is enabled on the current node when a datafeed is configured with a remote index pattern.
When recovering a shard locally, we use a translog snapshot from
newSnapshotFromGen which consists of all readers from a certain
generation. In the test, we use newSnapshotFromMinSeqNo for the
expectation. The snapshot of this method includes only readers
containing operations in the requesting range.
Closes#46022
If a node is misconfigured to talk to remote node HTTP port (instead of
transport port) eventually it will receive an HTTP response from the
remote node on transport port (this happens when a node sends
accidentally line terminating byte in a transport request).
If this happens today it results in a non-friendly log message and a
long stack trace.
This commit adds a check if a malformed response is HTTP response. In
this case, a concise log message would appear.
(cherry picked from commit 911d02b7a9c3ce7fe316360c127a935ca4b11f37)
This commit modifies the HTTP server used in S3BlobStoreRepositoryTests
so that it randomly returns server errors for any type of request executed by
the SDK client. It is now possible to verify that the repository tests are s
uccessfully completed even if one or more errors were returned by the S3
service in response of a blob upload, a blob deletion or a object listing request
etc.
Because injecting errors forces the SDK client to retry requests, the test limits
the maximum errors to send in response for each request at 3 retries.
* [ML] Regression dependent variable must be numeric
This adds a validation that the dependent variable of a regression
analysis must be numeric.
* Address review comments and fix some problems
In addition to addressing the review comments, this
commit fixes a few issues I found during testing.
In particular:
- if there were mappings for required fields but they were
not included we were not reporting the error
- if explicitly included fields had unsupported types we were
not reporting the error
Unfortunately, I couldn't get those fixed without refactoring
the code in `ExtractedFieldsDetector`.
When a query contains a mandatory clause that doesn't track the max score per
block, we disable the max score optimization. Previously, we were doing this by
wrapping the collector with a FilterCollector that always returned
ScoreMode.COMPLETE.
However we weren't adjusting totalHitsThreshold, so the collector could still
call Scorer#setMinCompetitiveScore. It is against the method contract to call
setMinCompetitiveScore when the score mode is COMPLETE, and some scorers like
ReqOptSumScorer throw an error in this case.
This commit tries to disable the optimization by always setting
totalHitsThreshold to max int, as opposed to wrapping the collector.

Today we might carry on a big merge uncommitted and therefore
occupy a significant amount of diskspace for quite a long time
if for instance indexing load goes down and we are not quickly
reaching the translog size threshold. This change will cause a
flush if we hit a significant merge (512MB by default) which
frees diskspace sooner.
