It seems this test only fails with `FsRepository` and mostly just barely times out (takes just a little over 30s to go green).
I think just increasing the timeout should be fine as a fix here as it's a little interesting to check larger amounts of
data in this test generally speaking.
Closes#39299
This change ensures that we call the listener for partial merge failure **before**
calling the completion listener in order to avoid race condition in tests.

The `SourceLookup` class provides access to the _source for a particular
document, specified through `SourceLookup#setSegmentAndDocument`. Previously
the search context contained a single `SourceLookup` that was shared between
different fetch subphases. It was hard to reason about its state: is
`SourceLookup` set to the expected document? Is the _source already loaded and
available?
Instead of using a global source lookup, the fetch hit context now provides
access to a lookup that is set to load from the hit document.
This refactor closes#31000, since the same `SourceLookup` is no longer shared
between the 'fetch _source phase' and script execution.
The oversize algorithm was allocating more pages than necessary to accommodate `minTargetSize`.
An example would be that a 16k page size and 15k `minTargetSize` would result in a new size of 32k (2 pages).
The difference between the minimum number of necessary pages and the estimated size then keeps growing as sizes increase.
I don't think there is much value in preemptively allocating pages by over-sizing aggressively since the behavior of
the system is quite different from that of a single array where over-sizing avoids copying
once the minimum target size is more than a single page.
Relates #60173 which lead me to this when `BytesStreamOutput` would allocate a large number of never used
pages during serialization of repository metadata.
Instances of `BlobStoreIndexShardSnapshots` can be of non-trivial size. In case of snapshotting a larger
number of shards the previous execution order would lead to memory use proportional to the number of shards
for these objects. With this change, the number of these objects on heap is bounded by the size of the snapshot
pool (except for in the BwC format path).
This PR makes it so that they are written to the repository at the earliest possible point in time
so that they can be garbage collected.
If shard generations are used, we can safely write these right at the beginning of the shard snapshot.
If shard generations are not used we can only write them at the end of the shard snapshot after all
other blobs have been written.

* SQL: Add option to provide the delimiter for the CSV format (#59907)
* Add option to provide the delimiter to the CSV fmt
This adds the option to provide the desired character as the separator
for the CSV format (the default remains comma).
A set of characters are excluded though - like CR, LF, `"` - to avoid
slipping onto the CSV-dialects slope. The tab is also forbidden, the
user needs to choose the "tsv" format explicitely.
Update the doc to make it clear that the textual CSV, TSV and TXT
formats pass the cursor back to the user through the Cursor HTTP header.

For all OSS plugins (except repository-* and discovery-*) integTest
task is now a no-op and all of the tests are now executed via a test,
yamlRestTest, javaRestTest, or internalClusterTest.
This commit does NOT convert the discovery-* and repository-* since they
are bit more complex then the rest of tests and this PR is large enough.
Those plugins will be addressed in a future PR(s).
This commit also fixes a minor issue that did not copy the rest api
for projects that only had YAML TEST tests.

This commit adds compatibility testing of our JDBC driver against
different Elasticsearch versions. Although we are really testing the
forwards compatibility nature of the JDBC driver we model the testing
the same as we do existing BWC tests, that is, with the current branch
fetching the earlier versions of the artifact that is to be tested. In
this case, that's the JDBC driver itself.
Because the tests include the JDBC driver jar on it's classpath we had
to change the packaging of the driver jar in order to avoid jarhell and
other conflicting dependency issues when using an old JDBC driver with
later branches. For this we simply relocate all driver dependencies in
the shadow jar under a "shadowed" package. This allows the JDBC driver
to use the correct version of Elasticsearch libs classes, while the
tests themselves use their versions. Since this required a change to the
driver jar compatibility testing can only go back as far as that version
which at the time of this commit is 7.8.1.
Prior to this change ML memory estimation processes for a
given job would always use the same named pipe names. This
would often cause one of the processes to fail.
This change avoids this risk by adding an incrementing counter
value into the named pipe names used for memory estimation
processes.

The retention run goes through a number of steps and can randomly take more than 10s.
=> increased timeout to 30s like we did in other spots in this test
Also, noticed that we had a hard wait of 10s in this test, removed it and adjusted following
busy assert in a way that can deal with a missing snapshot (from when the assert runs before
the snapshot was put into the CS).
Closes#60336
In order to unify model inference and analytics results we
need to write the same fields.
prediction_probability and prediction_score are now written
for inference calls against classification models.
CCR will stop functioning if the master node is on 7.8, but data nodes
are before that version because the master node considers that all data
nodes do not have the remote cluster client role. This commit allows CCR
work on data nodes with legacy roles only.

Changes:
* Adds the `number_of_routing_shards` index setting to index modules docs.
* Updates the split API docs to mention that `number_of_routing_shards`
is a static setting.
This sets up all indexing to one of our write aliases to require it actually be an alias.
This allows failures scenarios to be captured quickly, loudly, and then potentially recovered.
This fixes the behavior of the snapshot state machine in the following edge case:
1. Snapshot is running
2. Delete/abort for the snapshot is started
3. Snapshot fails to finalize
We were not removing the failed snapshot id from the list of snapshots to delete in the delete.
This lead to an error in the repository, which throws if we try to delete a non-existing snapshot.
This commmit updates the deletions in progress by removing the failed snapshot id.
The fact that this could lead to snapshot delete entries without any snapshot ids is not optimized
on purpose because it allows for another attempt at writing clean `RepositoryData` and will run basic
cleanup on the repository (root level blobs and stale indices) and thus bring the repository back into
a clean state after a failed finalization.
Closes#60274
The test assumed that the master fail-over would always work out as a single step.
This is not guaranteed however and we can randomly see master failing over twice,
in which case the transport listener will be failed on the node that stops being
leader and we have to catch an exception for the deletes as well just like we do
for the snapshot.
Closes#60262
