This commit namespaces the existing processors setting under the "node"
namespace. In doing so, we deprecate the existing processors setting in
favor of node.processors.
Customers occasionally discover a known behavior in Elasticsearch's pagination that does not appear to be documented. This warning is intended to educate customers of this behavior while still highlighting alternative solutions.
This change adds a new SSL context
xpack.notification.email.ssl.*
that supports the standard SSL configuration settings (truststore,
verification_mode, etc). This SSL context is used when configuring
outbound SMTP properties for watcher email notifications.

Since #45136, we use soft-deletes instead of translog in peer recovery.
There's no need to retain extra translog to increase a chance of
operation-based recoveries. This commit ignores the translog retention
policy if soft-deletes is enabled so we can discard translog more
quickly.
Backport of #45473
Relates #45136
Today, when rolling a new translog generation, we block all write
threads until a new generation is created. This choice is perfectly
fine except in a highly concurrent environment with the translog
async setting. We can reduce the blocking time by pre-sync the
current generation without writeLock before rolling. The new step
would fsync most of the data of the current generation without
blocking write threads.

* [ML] Adding data frame analytics stats to _usage API (#45820)
* [ML] Adding data frame analytics stats to _usage API
* making the size of analytics stats 10k
* adjusting backport
Adds index versioning for the internal data frame transform index. Allows for new indices to be created and referenced, `GET` requests now query over the index pattern and takes the latest doc (based on INDEX name).
When Watcher is stopped and there are still outstanding watches running
Watcher will report it self as stopped. In normal cases, this is not problematic.
However, for integration tests Watcher is started and stopped between
each test to help ensure a clean slate for each test. The tests are blocking
only on the stopped state and make an implicit assumption that all watches are
finished if the Watcher is stopped. This is an incorrect assumption since
Stopped really means, "I will not accept any more watches". This can lead to
un-predictable behavior in the tests such as message : "Watch is already queued
in thread pool" and state: "not_executed_already_queued".
This can also change the .watcher-history if watches linger between tests.
This commit changes the semantics of a manual stopping watcher to now mean:
"I will not accept any more watches AND all running watches are complete".
There is now an intermediary step "Stopping" and callback to allow transition
to a "Stopped" state when all Watches have completed.
Additionally since this impacts how long the tests will block waiting for a
"Stopped" state, the timeout has been increased.

In internal test clusters tests we check that wiping all indices was acknowledged
but in REST tests we didn't.
This aligns the behavior in both kinds of tests.
Relates #45605 which might be caused by unacked deletes that were just slow.
* [DOCS] Add template docs to scripts. Reorder template examples.
* Adds a 'Search template' section to the 'How to use scripts' chapter.
This links to the 'Search template' chapter for detailed info and
examples.
* Reorders and retitles several examples in the 'Search template'
chapter. This is primarily to make examples for storing, deleting, and
using search templates more prominent.

The system property es.http.cname_in_publish_address is deprecated
starting from 7.0.0 and deprecation warning should be added if the
property is specified.
This PR will go to 7.x and master.
Follow-up PR to remove es.http.cname_in_publish_address property
completely will go to the master.

This commit adds tests to verify the behavior of the S3BlobContainer and
its underlying AWS SDK client when the remote S3 service is responding
errors or not responding at all. The expected behavior is that requests are
retried multiple times before the client gives up and the S3BlobContainer
bubbles up an exception.
The test verifies the behavior of BlobContainer.writeBlob() and
BlobContainer.readBlob(). In the case of S3 writing a blob can be executed
as a single upload or using multipart requests; the test checks both scenario
by writing a small then a large blob.
* There is no point in listing out every shard over and over when the `index-N` blob in the shard contains a list of all the files
* Rebuilding the `index-N` from the `snap-${uuid}.dat` blobs does not provide any material benefit. It only would in the corner case of a corrupted `index-N` but otherwise uncorrupted blobs since we neither check the correctness of the content of all segment blobs nor do we do a similar recovery at the root of the repository.
* Also, at least in version `6.x` we only mark a shard snapshot as successful after writing out the updated `index-N` blob so all snapshots that would work with `7.x` and newer must have correct `index-N` blobs
=> Removed the rebuilding of the `index-N` content from `snap-${uuid}.dat` files and moved to only listing `index-N` when taking a snapshot instead of listing all files
=> Removed check of file existence against physical blob listing
=> Kept full listing on the delete side to retain full cleanup of blobs that aren't referenced by the `index-N`
This PR introduces a mechanism to cancel a search task when its corresponding connection gets closed. That would relief users from having to manually deal with tasks and cancel them if needed. Especially the process of finding the task_id requires calling get tasks which needs to call every node in the cluster.
The implementation is based on associating each http channel with its currently running search task, and cancelling the task when the previously registered close listener gets called.
* It appears this test that is specific to how the BSD network stack works
does randomly fail on Windows => disabling it since it's not clear that it
should work on Windows in a stable way
* Fixes#45777
Today we can release a Store using CancellableThreads. If we are holding
the last reference, then we will verify the node lock before deleting
the store. Checking node lock performs some I/O on FileChannel. If the
current thread is interrupted, then the channel will be closed and the
node lock will also be invalid.
Closes#45237
This commit moves many features of individual distro tests into the base
class so that other test cases can utilize them. It also standardizes
the pattern for tests adding assumptions for the particular
distributions to test.
* Add is_write_index column to cat.aliases (#44772)
Aliases have had the option to set `is_write_index` since 6.4,
but the cat.aliases action was never updated.
* correct version bounds to 7.4
After the PR #45676 onFailure is now called before the indexer state has transitioned out of indexing.
To fix these tests, I added a new check to make sure that we don't mark it as failed until AFTER doSaveState is called with a STARTED indexer.
Following our own guidelines, SLM should use rollover instead of purely
time-based indices to keep shard counts low. This commit implements lazy
index creation for SLM's history indices, indexing via an alias, and
rollover in the built-in ILM policy.
Most of our CLI tools use the Terminal class, which previously did not provide methods for writing to standard output. When all output goes to standard out, there are two basic problems. First, errors and warnings are "swallowed" in pipelines, making it hard for a user to know when something's gone wrong. Second, errors and warnings are intermingled with legitimate output, making it difficult to pass the results of interactive scripts to other tools.
This commit adds a second set of print commands to Terminal for printing to standard error, with errorPrint corresponding to print and errorPrintln corresponding to println. This leaves it to developers to decide which output should go where. It also adjusts existing commands to send errors and warnings to stderr.
Usage is printed to standard output when it's correctly requested (e.g., bin/elasticsearch-keystore --help) but goes to standard error when a command is invoked incorrectly (e.g. bin/elasticsearch-keystore list-with-a-typo | sort).
This commit adds a destructiveDistroTest task which depends on all of
the distribution specific destructive tasks, which can be used by CI.

* Repository Cleanup Endpoint (#43900)
* Snapshot cleanup functionality via transport/REST endpoint.
* Added all the infrastructure for this with the HLRC and node client
* Made use of it in tests and resolved relevant TODO
* Added new `Custom` CS element that tracks the cleanup logic.
Kept it similar to the delete and in progress classes and gave it
some (for now) redundant way of handling multiple cleanups but only allow one
* Use the exact same mechanism used by deletes to have the combination
of CS entry and increment in repository state ID provide some
concurrency safety (the initial approach of just an entry in the CS
was not enough, we must increment the repository state ID to be safe
against concurrent modifications, otherwise we run the risk of "cleaning up"
blobs that just got created without noticing)
* Isolated the logic to the transport action class as much as I could.
It's not ideal, but we don't need to keep any state and do the same
for other repository operations
(like getting the detailed snapshot shard status)
This change adds a new option called user_dictionary_rules to
Kuromoji's tokenizer. It can be used to set additional tokenization rules
to the Japanese tokenizer directly in the settings (instead of using a file).
This commit also adds a check that no rules are duplicated since this is not allowed
in the UserDictionary.
Closes#25343
This commit updates the documentation to
- use the batch file included with the zip distribution; the exe file is included in the MSI only.
- introduce a space between the -E arguments and their values. Without a space (or quoted, but adding a space is cleaner), the argument will fail with PowerShell
