Adds tracking for the API calls performed by the Azure Storage
underlying SDK. It relies on the ability to hook a request
listener into the OperationContext.
Backport of #56773
Previously `COUNT(DISTINCT <literal>)` was returning the same result
as `COUNT(<literal>)` which is not correct as it should always return 1
if there is at least one matching row (bucket if there is a GROUP BY),
or 0 otherwise.

Elasticsearch requires that a HttpRequest abstraction be implemented
by http modules before server processing. This abstraction controls when
underlying resources are released. This commit moves this abstraction to
be created immediately after content aggregation. This change will
enable follow-up work including moving Cors logic into the server
package and tracking bytes as they are aggregated from the network
level.
Now that #56526 is merged, we do not need to explicitly disable
the diagnostic trust manager for all of our test clusters - we do
this dynamically in runtime if the combination of java version and
JSSE provider dictates that.
Add tracking for regular and multipart uploads.
Regular uploads are categorized as PUT.
Multi part uploads are categorized as POST.
The number of documents created for the test #testRequestStats
have been increased so all upload methods are exercised.
Backport of #56826
PR #56893 was supposed to randomise the iteration count in
`testDataOnlyNodePersistence` but this change was mistakenly omitted. This
commit addresses this.
This test failed if all 1000 top-level `rarely()` calls in the loop returned
`false`, because then we would never set the term of the persisted state. This
commit fixes this by adding an earlier call to `persistedState#setCurrentTerm`.
It also changes the test to clean up the threadpools it starts whether it
passes or fails.
Throttling nightly cleanup as much as we do has been over cautious.
Night cleanup should be more lenient in its throttling. We still
keep the same batch size, but now the requests per second scale
with the number of data nodes. If we have more than 5 data nodes,
we don't throttle at all.
Additionally, the API now has `requests_per_second` and `timeout` set.
So users calling the API directly can set the throttling.
This commit also adds a new setting `xpack.ml.nightly_maintenance_requests_per_second`.
This will allow users to adjust throttling of the nightly maintenance.
Add tracking for multipart and resumable uploads for GoogleCloudStorage.
For resumable uploads only the last request is taken into account for
billing, so that's the only request that's tracked.
Backport of #56821
When reading/writing the individual doc responses in the context
of a bulk shard response there is no need to serialize the `ShardId`
over and over. This can waste a lot of memory when handling large bulk
requests.
Fixes the fact that repository metadata with the same settings still results in
multiple settings instances being cached as well as leaking settings on closing
a repository.
Closes#56702
This assertion is too strict. A snapshot will be removed from the cluster state
on the CS thread before it is removed from the listeners map on the snapshot thread pool.
Throughout the removal from the cluster state and listener map, the snapshot is tracked
in `endingSnapshots` though, so we can relax the assertion accordingly and are still able
to catch leaked listeners.
Closes#56607
In the unlikely event that the data nodes started snapshotting the
shards already (and hence got blocked on the data blobs) before the
master has applied the cluster state to its own `SnapshotsService` on
the CS applier thread, we can get a `SnapshotMissingException` here which
breaks the busy assert loop so we have to deal with it explicitly.
Closes#56858
In most cases we are seeing a `PooledHeapByteBuf` here now. No need to
redundantly create an new `ByteBuffer` and single element array for it
here when we can just directly unwrap its internal `byte[]`.
The version number componenent can't equal or exceed the revision
multiplier.
This fixes a the VersionTests unit test.

* Adds support for MIN, MAX, AVG, SUM aggregates acting on literals.
SELECT SUM(1) FROM index
and
SELECT SUM(1), AVG(2)
work both on indices and as local execution.

WatcherIndexTemplateRegistry as of https://github.com/elastic/elasticsearch/pull/52962
requires all nodes to be on 7.7.0 before it allows the version 11 index template to be
installed.
While in a mixed cluster, nothing prevents Watcher from running on the new
host before the all of the nodes are on 7.7.0. This will result in the
.watcher-history-11* index without the proper mappings. Without the proper
mapping a single document (for a large watch) can exceed the default 1000 field
limit and cause error to show in the logs.
This commit ensures the same logic for writing to the index is applied as for
installing the template. In a mixed cluster, the `10` index template will continue
to be written. Only once all of nodes are on 7.7.0+ will the `11` index template
be installed and used.
closes#56732
Currently it is possible that a sniff connection round is occurring as
we enter another test loop in testEnsureWeReconnect. The problem is that
once we enter another loop, closing the connection manually can cause
this pre-existing connection round to fail. This round failing can fail
the test. This commit fixes the issue by ensuring that there are no
in-progress connections before entering another loop.
It was relying on the compensated sum working but the test framework was
dodging it. This forces the accuracy tests to come from a single shard
where we get the proper compensated sum.
Closes#56757
We get the number of shards and replicas with our bare hands in index
metadata, rather than letting the settings infrastructure do the work
for us. This commit switches to using the settings infrastructure.
Today a 7.x node logs `cluster UUID set to [...]` on every cluster state update
received from a 6.8 master, because 6.8 nodes are not able to commit the
cluster UUID properly. We could try and deduplicate these logs somehow, but
that would introduce a good deal of complexity. Instead, this commit suppresses
these logs entirely when receiving cluster state updates from a 6.8 master.
In DF analytics classification, it is possible to use no samples
of a class if its cardinality is too low.
This commit fixes this by ensuring the target sample count can never be zero.
Backport of #56783
* JDBC: fix access to the Manifest for non-entry JAR
The JDBC driver will attempt to read its version from the Manifest file
embedded into its JAR. The URL pointing to the JAR can be provided in a
few ways.
So far, accessing the Manfiest was attempted by getting a URLConnection
out of the URL and then getting an input stream out of this connection.
For file JAR URLs, this only works however if the URL points to the
driver as a JAR file entry (i.e. <sub-url>!/jdbc-driver.jar!/). If
that's not the case, the JarURLConnection will throw an IOException.
This commit fixes that: in case the URL points to a JAR entry
(jar:file:<path>/jdbc-driver.jar!/), the manifest is read directly with
JarURLConnection#getManifest().

In some cases the Enrich processor factory may be called before it is
ready to create processors. While these calls are usually made in error,
the response from the Enrich processor is an NPE which is almost always
an unhelpful error when debugging an issue.
Added support for decompression at LLRC and added integration test

This change aims to fix our setup in CI so that we can run 7.x in
FIPS 140 mode. The major issue that we have in 7.x and did not
have in master is that we can't use the diagnostic trust manager
in FIPS mode in Java 8 with SunJSSE in FIPS approved mode as it
explicitly disallows the wrapping of X509TrustManager.
Previous attempts like #56427 and #52211 focused on disabling the
setting in all of our tests when creating a Settings object or
on setting fips_mode.enabled accordingly (which implicitly disables
the diagnostic trust manager). The attempts weren't future proof
though as nothing would forbid someone to add new tests without
setting the necessary setting and forcing this would be very
inconvenient for any other case ( see
#56427 (comment) for the full argumentation).
This change introduces a runtime check in SSLService that overrides
the configuration value of xpack.security.ssl.diagnose.trust and
disables the diagnostic trust manager when we are running in Java 8
and the SunJSSE provider is set in FIPS mode.
* [Transform] add support for terms agg in transforms (#56696)
This adds support for `terms` and `rare_terms` aggs in transforms.
The default behavior is that the results are collapsed in the following manner:
`<AGG_NAME>.<BUCKET_NAME>.<SUBAGGS...>...`
Or if no sub aggs exist
`<AGG_NAME>.<BUCKET_NAME>.<_doc_count>`
The mapping is also defined as `flattened` by default. This is to avoid field explosion while still providing (limited) search and aggregation capabilities.
This is a followup to #56632. Tests that had to be changed
to mock the C++ log handler more accurately need to be more
careful about when that stream ends, as ending of that
stream is used to detect crashes in the production system.
Fixes#56796
Mapper.Builder currently has some complex generics on it to allow fluent builder
construction. However, the second parameter, a return type from the build() method,
is unnecessary, as we can use covariant return types. This commit removes this second
generic parameter.
