Backport of #48448. Make a number of changes so that code in the libs and
modules directories are more resilient to automatic formatting. This covers:
* Remove string concatenation where JSON fits on a single line
* Move some comments around to they aren't auto-formatted to a strange
place
This change adds a new merge policy that interleaves eldest and newest segments picked by MergePolicy#findForcedMerges
and MergePolicy#findForcedDeletesMerges. This allows time-based indices, that usually have the eldest documents
first, to be efficient at finding the most recent documents too. Although we wrap this merge policy for all indices
even though it is mostly useful for time-based but there should be no overhead for other type of indices so it's simpler
than adding a setting to enable it. This change is needed in order to ensure that the optimizations that we are working
on in # remain efficient even after running a force merge.

In repository integration tests, we drain the HTTP request body before
returning a response. Before this change this operation was done using
Streams.readFully() which uses a 8kb buffer to read the input stream, it
now uses a 1kb for the same operation. This should reduce the allocations
made during the tests and speed them up a bit on CI.

I think the problem is that the master is trying to relocate the "upgraded_scroll" shard back to
the node on which it was previously allocated, but to which it can't be allocated now due to the
shard lock being held because of an in-progress scroll. As the master keeps on retrying and
retrying (and indefinitely tries so because max_retries does not apply to relocations, it blocks
any other lower-prioritized task from completing, which leads to the rolling upgrade tests failing
(see #48395).
Closes#48395
This commit simplifies and standardizes our usage of the Gradle Shadow
plugin to conform more to plugin conventions. The custom "bundle" plugin
has been removed as it's not necessary and performs the same function
as the Shadow plugin's default behavior with existing configurations.
Additionally, this removes unnecessary creation of a "nodeps" artifact,
which is unnecessary because by default project dependencies will in
fact use the non-shadowed JAR unless explicitly depending on the
"shadow" configuration.
Finally, we've cleaned up the logic used for unit testing, so we are
now correctly testing against the shadow JAR when the plugin is applied.
This better represents a real-world scenario for consumers and provides
better test coverage for incorrectly declared dependencies.

This commit bumps the bundled JDK to 13.0.1+9. Since AdoptOpenJDK did
not release 13.0.1+9 for Windows, this commit also enables that the
bundled JDK version can vary by platform.
Due to a bug, GETing a snapshot can cause a RespositoryException to be
thrown. This error is transient and should be retried, rather than
causing the test to fail. This commit converts those
RepositoryExceptions into AssertionErrors so that they will be retried
in code wrapped in assertBusy.
When checking for the existence of a document in the ILM/CCR integration
tests, `assertDocumentExists` makes an HTTP request and checks the
response code. However, if the repsonse code is not successful, the call
will throw a `ResponseException`. `assertDocumentExists` is often called
inside an `assertBusy`, and wrapping the `ResponseException` in an
`AssertionError` will allow the `assertBusy` to retry.
In particular, this fixes an issue with `testCCRUnfollowDuringSnapshot`
where the index in question may still be closed when the document is
requested.
This commit moves JVM options that we are setting on behalf of the user
that we do not expect them to fiddle with out of the jvm.options
configuration file and into the JVM options parser. In this way, we
discourage fiddling with these settings, but more importantly, we ensure
that as we evolve or add to these settings that a user would pick these
pick instead of being left behind if they have a modified jvm.options
file and do not pick any new that come with the distribution.
This is in preparation to move to nested virtualization which is much slower
than the bare metal setup we use right now, but parallelizes better
resulting in a net win.t
We no longer run the sample tests in CI, so it's safe to create a task
for every project.
This will make it easier to set them up in a matrix like fashion.
Backport of #48452.
The SAML tests have large XML documents within which various parameters
are replaced. At present, if these test are auto-formatted, the XML
documents get strung out over many, many lines, and are basically
illegible.
Fix this by using named placeholders for variables, and indent the
multiline XML documents.
The tests in `SamlSpMetadataBuilderTests` deserve a special mention,
because they include a number of certificates in Base64. I extracted
these into variables, for additional legibility.
Today, we hold the engine readLock while refreshing. Although this
choice simplifies the correctness reasoning, it can block IndexShard
from closing if warming an external reader takes time. The current
implementation of refresh does not need to hold readLock as
ReferenceManager can handle errors correctly if the engine is closed in
midway.
This PR is a prerequisite that we need to solve #47186.
Our JVM ergonomics extract max heap size from JDK PrintFlagsFinal output.
On JDK 8, there is a system-dependent bug where memory sizes are cast to
32-bit integers. On affected systems (namely, Windows), when 1/4 of physical
memory is more than the maximum integer value, the output of PrintFlagsFinal
will be inaccurate. In the pathological case, where the max heap size would
be a multiple of 4g, the test will fail.
The practical effect of this bug, beyond test failures, is that we may set
MaxDirectMemorySize to an incorrect value on Windows. This commit adds a
warning about this situation during startup.
This commit ensures that the creation of a DocumentSubsetReader does not
eagerly resolve the role query and the number of docs that match.
We want to delay this expensive operation in order to ensure that we really
need this information when we build it. For this reason the role query and the
number of docs are now resolved on demand. This commit also depends on
https://issues.apache.org/jira/browse/LUCENE-9003 that will also compute the global
number of docs lazily.
* Extract remote "sniffing" to connection strategy (#47253)
Currently the connection strategy used by the remote cluster service is
implemented as a multi-step sniffing process in the
RemoteClusterConnection. We intend to introduce a new connection strategy
that will operate in a different manner. This commit extracts the
sniffing logic to a dedicated strategy class. Additionally, it implements
dedicated tests for this class.
Additionally, in previous commits we moved away from a world where the
remote cluster connection was mutable. Instead, when setting updates are
made, the connection is torn down and rebuilt. We still had methods and
tests hanging around for the mutable behavior. This commit removes those.
* Introduce simple remote connection strategy (#47480)
This commit introduces a simple remote connection strategy which will
open remote connections to a configurable list of user supplied
addresses. These addresses can be remote Elasticsearch nodes or
intermediate proxies. We will perform normal clustername and version
validation, but otherwise rely on the remote cluster to route requests
to the appropriate remote node.
* Make remote setting updates support diff strategies (#47891)
Currently the entire remote cluster settings infrastructure is designed
around the sniff strategy. As we introduce an additional conneciton
strategy this infrastructure needs to be modified to support it. This
commit modifies the code so that the strategy implementations will tell
the service if the connection needs to be torn down and rebuilt.
As part of this commit, we will wait 10 seconds for new clusters to
connect when they are added through the "update" settings
infrastructure.

* Fix .tasks index strict mapping: parent_id should be parent_task_id
The .tasks index has mappings that's strictly defined. `parent_task_id`
was defined as `parent_id` though which would cause an exception in case
a task is persisted that has a parent task id set.
While at it, a couple of compiler warnings were addressed and a test
request builder was removed in favour of using its corresponding request.
* increment version
The expand phase is always created providing a function that builds
the next phase to be run, which has a single purpose: sending the
response back. Such small search phase is not necessary and causes some
issues when reporting search progress and counting the search phases
that need to be executed and that are already executed. We can simply
rather send back the response, without creating a specific phase for that.
In #47176 we changed the internal HTTP server that emulates
the Azure Storage service so that it includes a response body
for injected errors. This fixed most of the issues reported in
#47120 but sadly I missed to map one error to its Azure
equivalent, and it triggered some CI failures today.
Closes#47120
This relates to the effort towards #46250. We added
tracking of the shard generation for successful
snapshots to `8.0`.
This assertion isn't correct though. While an `8.0`
master won't create an entry with sucess state and
a null shard generation it may still (on e.g. master
failover) send a success entry created by a 7.x master
with a `null` generation over the wire.
Closes#47406
This changes the queries equals() method so that the boost factors for each term
are considered for the equality calculation. This means queries are only equal
if both their terms and associated boosts match. The ordering of the terms
doesn't matter as before, which is why we internally need to sort the terms and
boost for comparison on the first equals() call like before. Boosts that are
`null` are considered equal to boosts of 1.0f because topLevelQuery() will only
wrap into BoostQuery if boost is not null and different from 1f.
Closes#48184
This commit changes the REST API spec slm.get_lifecycle's policy_id url part to be of type "list", in line with other REST API specs that accept a comma-separated list of values.
Closes#47765
BytesReference is currently an abstract class which is extended by
various implementations. This makes it very difficult to use the
delegation pattern. The implication of this is that our releasable
BytesReference is a PagedBytesReference type and cannot be used as a
generic releasable bytes reference that delegates to any reference type.
This commit makes BytesReference an interface and introduces an
AbstractBytesReference for common functionality.
The AbstractHlrcWriteableXContentTestCase was replaced by a better test
case a while ago, and this is the last two instances using it. They have
been converted and the test is now deleted.
Ref #39745
This PR makes the following updates:
* Update the supported query types to include `prefix` and `wildcard`.
* Specify that queries accept index aliases.
* Clarify that when querying on a remote index name, the separator `:` must be
present.
