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.

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

Regression analysis support missing fields. Even more, it is expected
that the dependent variable has missing fields to the part of the
data frame that is not for training.
This commit allows to declare that an analysis supports missing values.
For such analysis, rows with missing values are not skipped. Instead,
they are written as normal with empty strings used for the missing values.
This also contains a fix to the integration test.

The java based distribution tests currently have a single Tests class
which encapsulates all of the tests for a particular distribution. The
test task in gradle then depends on all distributions being built, and
each individual tests class looks for the particular distribution it is
trying to test. This means that reproducing a single test failure
triggers all the distributions to be built, even though only one is
needed for the test.
This commit reworks the java distribution tests to pass in a particular
distribution to be tested, and changes the base test classes to be
actual test classes which have assumptions around which distributions
they operate on. For example, the archives tests will be skipped when
run with an rpm distribution, and vice versa for the package tests. This
makes reproduction much more granular. It also also better splitting up
tests around a particular use case. For example, all tests for systemd
behavior can be in one test class, and run independently of all tests
against rpm/deb distributions.

Similar to PR #45030 integration test testDontCacheScripts() was moved to unit test AvgAggregatorTests#testDontCacheScripts.

If the background refresh is running, but not finished yet then the
document might not be visible to the next search. Thus, if
scheduledRefresh returns false, we need to wait until the background
refresh is done.

The setting index.soft_deletes.retention.operations is no longer needed
nor recommended in CCR. We, therefore, should hint users about the
retention leases period setting instead when operations are no longer
available for replicating.
We cannot know how long the analysis will take to complete thus we should not have
a timeout. Note that if the process crashes, the result processor will pick the
exception due to the stream closing.

* [ML][Data frame] fixing failure state transitions and race condition (#45627)
There is a small window for a race condition while we are flagging a task as failed.
Here are the steps where the race condition occurs:
1. A failure occurs
2. Before `AsyncTwoPhaseIndexer` calls the `onFailure` handler it does the following:
a. `finishAndSetState()` which sets the IndexerState to STARTED
b. `doSaveState(...)` which attempts to save the current state of the indexer
3. Another trigger is fired BEFORE `onFailure` can fire, but AFTER `finishAndSetState()` occurs.
The trick here is that we will eventually set the indexer to failed, but possibly not before another trigger had the opportunity to fire. This could obviously cause some weird state interactions. To combat this, I have put in some predicates to verify the state before taking actions. This is so if state is indeed marked failed, the "second trigger" stops ASAP.
Additionally, I move the task state checks INTO the `start` and `stop` methods, which will now require a `force` parameter. `start`, `stop`, `trigger` and `markAsFailed` are all `synchronized`. This should gives us some guarantees that one will not switch states out from underneath another.
I also flag the task as `failed` BEFORE we successfully write it to cluster state, this is to allow us to make the task fail more quickly. But, this does add the behavior where the task is "failed" but the cluster state does not indicate as much. Adding the checks in `start` and `stop` will handle this "real state vs cluster state" race condition. This has always been a problem for `_stop` as it is not a master node action and doesn’t always have the latest cluster state.

* Search enhancement: pinned queries (#44345)
Search enhancement: - new query type allows selected documents to be promoted above any "organic” search results.
This is the first feature in a new module `search-business-rules` which will house licensed (non OSS) logic for rewriting queries according to business rules.
The PinnedQueryBuilder class offers a new `pinned` query in the DSL that takes an array of promoted IDs and an “organic” query and ensures the documents with the promoted IDs rank higher than the organic matches.

Encapsulate the serialization/deserialization of SQL client classes.
Make configuration specific parameters (such as ZoneId) generic just
like the version and remove the need for consumer classes to manage them
individually.
This is not only consistent but also provides significant savings in the

* Add input and outut tracking of built bwc versions
This PR adds tracking of the bwc versions git has as input and all the
expected files as output.
The effect is that `gradlew` is not called at all when the git has
doesn't change and the version was allready built.
Previusly gradlew would be called for the bwc version and it would have
to configure the project and go trough up to date checks to figure out
that nothing changed.
This helps when working on bwc tests locally needing to run the test
multiple times.
This should also help in CI not re-build bwc versions across different
runs.
