Previously, the dot-index rules (namely, that indices with dot-prefixed
names should be either hidden indices or system indices) was done
before* template application, and so only checked for the `index.hidden`
setting in the request, ignoring if that setting was set via a template.
This commit moves that check to a different method, which is applied
after templates have been resolved and applied to the index settings.
This commit fixes another edge case in handling windows newlines in our
capture of stdout/stderr to log4j. The case is that the \r appears at
the beginning of the buffer when flushing, which would unintentionally
be emitted as an empty string. This commit skips the flush if only a \r
was found.

Currently, the logic for looking up `flattened` field types lives in the
top-level `FieldTypeLookup`. This PR moves it into a dedicated class
`DynamicKeyFieldTypeLookup`.
Segment(s) info blobs are already stored with their full content
in the "hash" field in the shard snapshot metadata as long as they are
smaller than 1MB. We can make use of this fact and never upload them
physically to the repo.
This saves a non-trivial number of uploads and downloads when restoring
and might also lower the latency of searchable snapshots since they can save
phyiscally loading this information as well.
- Enable SunJGSS provider for Kerberos tests
- Handle the fact that in the decrypt method in KeyStoreWrapper might
not throw immediately when the GCM cipher is from BouncyCastle FIPS
and we end up with a DataInputStream that has reached it's end.
- Disable tests, jarHell, testingConventions for ingest attachment
plugin. We don't support this plugin (and document this) in FIPS
mode.
- Don't attempt to install ingest-attachment in smoke-test-plugins
This commit changes how RestHandlers are registered with the
RestController so that a RestHandler no longer needs to register itself
with the RestController. Instead the RestHandler interface has new
methods which when called provide information about the routes
(method and path combinations) that are handled by the handler
including any deprecated and/or replaced combinations.
This change also makes the publication of RestHandlers safe since they
no longer publish a reference to themselves within their constructors.

Backport of #51950
We might leak a searcher if the target shard is removed (i.e., its index
is deleted) or relocated while we are creating a SearchContext from a
SearchRewriteContext.
Relates #51708Closes#52021
I labelled this non-issue for an unreleased bug introduced in #51708.
We can just put the `IndexId` instead of just the index name into the recovery soruce and
save one load of `RepositoryData` on each shard restore that way.
We need to either exclude null responses from the scroll search response
or always create a search context for every target shards, although that
scroll query can be written to match_no_docs. Otherwise, we won't find
search_context for subsequent scroll requests.
This commit implements the latter option as it's less error-prone.
Relates #51708
This change ensures that the rewrite of the shard request is executed in the network thread or in the refresh listener when waiting for an active shard. This allows queries that rewrite to match_no_docs to bypass the search thread pool entirely even if the can_match phase was skipped (pre_filter_shard_size > number of shards). Coordinating nodes don't have the ability to create empty responses so this change also ensures that at least one shard creates a full empty response while the other can return null ones. This is needed since creating true empty responses on shards require to create concrete aggregators which would be too costly to build on a network thread. We should move this functionality to aggregation builders in a follow up but that would be a much bigger change.
This change is also important for #49601 since we want to add the ability to use the result of other shards to rewrite the request of subsequent ones. For instance if the first M shards have their top N computed, the top worst document in the global queue can be pass to subsequent shards that can then rewrite to match_no_docs if they can guarantee that they don't have any document better than the provided one.
QueryBuilders that throw exceptions on shards when building the Lucene query
returns the full serialization of the query builder in the exception message.
For large queries that fails to execute due to the max boolean clause, this means
that we keep a reference of these big messages for every shard that participate
in the request. In order to limit the memory needed to hold these query shard
exceptions in the coordinating node, this change removes the query builder
serialization from the shard exception. The query is known by the user so
there should be no need to repeat it on every shard exception. We could also
omit the entire stack trace for known bad request exception but it would deserve
a separate issue/pr.
Closes#51843Closes#48910
When the `rare_terms` aggregation contained another aggregation it'd
break them. Most of the time. This happened because the process that it
uses to remove buckets that turn out not to be rare was incorrectly
merging results from multiple leaves. This'd cause array index out of
bounds issues. We didn't catch it in the test because the issue doesn't
happen on the very first bucket. And the tests generated data in such a
way that the first bucket always contained the rare terms. Randomizing
the order of the generated data fixed the test so it caught the issue.
Closes#51020
Currently, the same class `FieldCapabilities` is used both to represent the
capabilities for one index, and also the merged capabilities across indices. To
help clarify the logic, this PR proposes to create a separate class
`IndexFieldCapabilities` for the capabilities in one index. The refactor will
also help when adding `source_path` information in #49264, since the merged
source path field will have a different structure from the field for a single index.
Individual changes:
* Add a new class IndexFieldCapabilities.
* Remove extra constructor from FieldCapabilities.
* Combine the add and merge methods in FieldCapabilities.Builder.
Currently, a mappings update request, where dynamic_mappings is an object
instead of an array, results in a http response with a 500 code. This PR checks
for this condition and throws a MapperParsingException like we do for other
malformed mapping cases.
Closes#51486
ActionListener.completeWith would catch exceptions from
listener.onResponse and deliver them to lister.onFailure, essentially
double notifying the listener. Instead we now assert that listeners do
not throw when using ActionListener.completeWith.

With the new mechanism for storing cluster state in lucene, we store
index metadata in multiple data paths too. This causes cluster state
publish to timeout too frequently with a 1s timeout, so increasing it to
5s. Also increasing follower check timeout to 5s since it also sometimes
has fsync in its timeout path and leader check for symmetry.
Closes#51329
While we use `== false` as a more visible form of boolean negation
(instead of `!`), the true case is implied and the true value does not
need to explicitly checked. This commit converts cases that have slipped
into the code checking for `== true`.
LoggingOutputStream reads a stream and breaks on newlines. This commit
fixes the behavior to account for windows newlines also containing `\r`.

This commit inlines the `weightShardAdded` and `weightShardRemoved` methods
from the `BalancedShardsAllocator#WeightFunction` that respectively add and
subtract 1 (±ε) from the result of `weight`. It then follows up with a number
of simplifications that this inlining enables.
As a side-effect it also somewhat reduces the number of calls to canRebalance
and canAllocate during rebalancing when there are multiple shards of the same
index on a node that is heavier than average.
When running Elasticsearch on a flaky network, we may see nodes leaving the
cluster with reason `disconnected`. It may be useful to the cluster
administrator to see the full exception that caused the disconnection, but this
is only available with `TRACE` level logging which commingles the details of
the problem with other messages that are not useful to end users.
This commit promotes logging of exceptions in `TcpTransport` from `TRACE` to
`DEBUG` to separate them from the truly `TRACE`-level messages.
This commit switches the strategy for managing dot-prefixed indices that
should be hidden indices from using "fake" system indices to an explicit
exclusions list that must be updated when those indices are converted to
hidden indices.
* Fix InternalEngineTests.testSeqNoAndCheckpoints
If we force flush while possibly triggering a merge the local checkpoint may change
from the expectation from the loop that just increments on every operation.
Closes#51604
There is no reason not to allow deletes in parallel to restores
if they're dealing with different snapshots.
A delete will not remove any files related to the snapshot that
is being restored if it is different from the deleted snapshot
because those files will still be referenced by the restoring
snapshot.
Loading RepositoryData concurrently to modifying it is concurrency
safe nowadays as well since the repo generation is tracked in the
cluster state.
Closes#41463
ActionListener.map would call listener.onFailure for exceptions from
listener.onResponse, but this means we could double trigger some
listeners which is generally unexpected. Instead, we should assume that
a listener's onResponse (and onFailure) implementation is responsible
for its own exception handling.
In #50259 we redirected stdout and stderr to log4j, to capture jdk
and external library messages. However, a typo in the method name used
to redirect the stream in java means stdout is currently being
duplicated twice, and stderr not captured. This commit corrects that
mistake. Unfortunately this is at a level that cannot really be tested,
thus we are still missing tests for this behavior.
We need to warm up the engine (i.e., perform an external refresh) before
accessing the external refresh. Note that we refresh externally before
allowing reading from a shard.

When checking if a device is up, today we can run into virtual ethernet
devices that disappear while we are in the middle of checking. This
leads to "no such device". This commit addresses such devices by
treating them as not being up, if they are virtual ethernet devices that
disappeared while we were checking.
This commit moves the logic that cancels search requests when the rest channel is closed
to a generic client that can be used by other APIs. This will be useful for any rest action
that wants to cancel the execution of a task if the underlying rest channel is closed by the
client before completion.
