* 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.

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.
This commit removes the randomization used by every execute call in the
high level rest tests. Previously every execute call, which can be many
calls per single test, would rely on a random boolean to determine if
they should use the sync or async methods provided to the execute
method. This commit runs the tests twice, using two different clusters,
both of them providing the value one time via a sysprop. This ensures
that the whole suite of tests is run using the sync and async code
paths.
Closes#39667
There is a watchdog in order to avoid long running (and expensive)
grok expressions. Currently the watchdog is thread based, threads
that run grok expressions are registered and after completion unregister.
If these threads stay registered for too long then the watch dog interrupts
these threads. Joni (the library that powers grok expressions) has a
mechanism that checks whether the current thread is interrupted and
if so abort the pattern matching.
Newer versions have an additional method to abort long running pattern
matching inside joni. Instead of checking the thread's interrupted flag,
joni now also checks a volatile field that can be set via a `Matcher`
instance. This is more efficient method for aborting long running matches.
(joni checks each 30k iterations whether interrupted flag is set vs.
just checking a volatile field)
Recently we upgraded to a recent joni version (#47374), and this PR
is a followup of that PR.
This change should also fix#43673, since it appears when unit tests
are ran the a test runner thread's interrupted flag may already have
been set, due to some thread reuse.
On data-only nodes we were not using the last persisted cluster state as base point to compute
what needed storage, but the last applied cluster state (but not necessarily properly persisted)
instead.
In #48392 we added a second computation of the sizes of the relocating shards
in `canRemain()` but passed the wrong value for `subtractLeavingShards`. This
fixes that. It also removes some unnecessary logging in a test case added in
the same commit.
This is a follow up of https://github.com/elastic/elasticsearch/issues/43453 where we added
a system property to disallow allocation awareness in search requests. Since search requests
will no longer check the allocation awareness attributes for routing in the next major version,
this change adds a deprecation warning on any setup that uses these attributes.

We have not seen much adoption of this experimental field type, and don't see a
clear use case as it's currently designed. This PR deprecates the field type in
7.x. It will be removed from 8.0 in a follow-up PR.
Previously there was a bug when an query inside script_score query
was rewritten. If min_score was not set and was equal to null,
we were converting it to float value which resulted to NPE.
This commit corrects this.
Closes#48081
Brings handling of out of bounds points in linestrings in line with
points. Now points with latitude above 90 and below -90 are handled
the same way as for points by adjusting the longitude by moving it by
180 degrees.

* Do not throw errors on unknown types in SearchAfterBuilder
The support for BigInteger and BigDecimal was added for XContent in
https://github.com/elastic/elasticsearch/pull/32888. However the SearchAfterBuilder
xcontent parser doesn't expect them to be present so it throws an AssertionError.
This change fixes this discrepancy by changing the AssertionError into an
IllegalArgumentException that will not cause the node to die when thrown.
Closes#48074
Today it is possible that the total size of all relocating shards exceeds the
total amount of free disk space. For instance, this may be caused by another
user of the same disk increasing their disk usage, or may be due to how
Elasticsearch double-counts relocations that are nearly complete particularly
if there are many concurrent relocations in progress.
The `DiskThresholdDecider` treats negative free space similarly to zero free
space, but it then fails when rendering the messages that explain its decision.
This commit fixes its handling of negative free space.
Fixes#48380
7.5+ for SLM requires [stats] object to exist in the cluster state.
When doing an in-place upgrade from 7.4 to 7.5+ [stats] does not exist
in cluster state, result in an exception on startup [1].
This commit moves the [stats] to be an optional object in the parser
and if not found will default to an empty stats object.
[1] Caused by: java.lang.IllegalArgumentException: Required [stats]
The comment says it needs random-access, but it passes `Long#MAX_VALUE` as the
lead cost, which forces sequential access, it should pass `0` instead. I took
advantage of this fix to improve the logic to leverage an estimation of the
number of times that `Bits#get` gets called to make better decisions.

This commit changes the test so that each node use a specific
service account and private key. It also changes how unique
request ids are generated for refresh token request using the
token itself, so that error count will be specific per node (each
node should execute a single refresh token request as tokens
are valid for 1 hour).

- Section about when the IdP SAML metadata do not contain a
SingleSignOnService that supports HTTP-Redirect binding.
