In some cases we want to deprecate a setting, and then automatically
upgrade uses of that setting to a replacement setting. This commit adds
infrastructure for this so that we can upgrade settings when recovering
the cluster state, as well as when such settings are dynamically applied
on cluster update settings requests. This commit only focuses on cluster
settings, index settings can build on this infrastructure in a
follow-up.
When requesting job stats for `_all`, all ES tasks are accepted
resulting to loads of cluster traffic and a memory overhead.
This commit correctly filters out non ML job tasks.
Closes#33515
We may use different global checkpoints to validate/normalize the range
of a change request if the global checkpoint is advanced between these
calls. If this is the case, then we generate an invalid request range.
This commit reverses the logic for CCR license checks in a few
actions. This is done so that the successful case, which tends to be a
larger block of code, does not require indentation.
We have some listeners in the CCR license tests that invoke Assert#fail
if the onSuccess method for the listener is unexpectedly invoked. This
can leave the main test thread hanging until the test suite times out
rather than failing quickly. This commit adds some latch countdowns so
that we fail quickly if these cases are hit.
In the multi-cluster-with-non-compliant-license tests, we try to write
out a java.policy to a temporary directory. However, if this temporary
directory does not already exist then writing the java.policy file will
fail. This commit ensures that the temporary directory exists before we
attempt to write the java.policy file.
This commit adds license checks for the auto-follow implementation. We
check the license on put auto-follow patterns, and then for every
coordination round we check that the local and remote clusters are
licensed for CCR. In the case of non-compliance, we skip coordination
yet continue to schedule follow-ups.
This commit ensures that we bootstrap a new history_uuid when force
allocating a stale primary. A stale primary should never be the source
of an operation-based recovery to another shard which exists before the
forced-allocation.

* CompoundProcessor is in the ingest package now
-> resolved
* Java generics don't offer type checking so nothing
can be done here -> remvoed TODO and test
* #16019 was closed and not acted on
-> todo can go away
Clean up on top of the last fix: if we skip the entire test case then
the test run would fail because we skipped all the tests. This adds a
dummy test case to prevent that. It is a fairly nasty work around I plan
to work on something that makes this not required any more anyway.
If we're running on a platform where we can't install syscall filters
Elasticsearch logs a message before it reads the data directory to get
the node name. Because that log message doesn't have a node name this
test will fail. Since we mostly run the test on OSes where we *can*
install the syscall filters we can fairly safely skip the test on OSes
where we can't install the syscall filters.
Closes#33540
I disabled one branch a few hours ago because it failed in CI. It looks
like other branches can also fail so I'll disable them as well and look
more closely on Monday.
Today when checking settings dependencies, we do not check if fallback
settings are present. This means, for example, that if
cluster.remote.*.seeds falls back to search.remote.*.seeds, and
cluster.remote.*.skip_unavailable and search.remote.*.skip_unavailable
depend on cluster.remote.*.seeds, and we have set search.remote.*.seeds
and search.remote.*.skip_unavailable, then validation will fail because
it is expected that cluster.ermote.*.seeds is set here. This commit
addresses this by also checking fallback settings when validating
dependencies. To do this, we adjust the settings exist method to also
check for fallback settings, a case that it was not handling previously.
Change the logging infrastructure to handle when the node name isn't
available in `elasticsearch.yml`. In that case the node name is not
available until long after logging is configured. The biggest change is
that the node name logging no longer fixed at pattern build time.
Instead it is read from a `SetOnce` on every print. If it is unset it is
printed as `unknown` so we have something that fits in the pattern.
On normal startup we don't log anything until the node name is available
so we never see the `unknown`s.
This change adds support for enable and disable user APIs to the high
level rest client. There is a common request base class for both
requests with specific requests that simplify the use of these APIs.
The response for these APIs is simply an empty object so a new response
class has been created for cases where we expect an empty response to
be returned.
Finally, the put user documentation has been moved to the proper
location that is not within an x-pack sub directory and the document
tags no longer contain x-pack.

We invoke force merge twice in the test to verify that recovery sources
are pruned when the global checkpoint advanced. However, if the global
checkpoint equals to the local checkpoint in the first force-merge, the
second force-merge will be a noop because all deleted docs are expunged
in the first merge already. We need to flush a new segment to make merge
happen so we can verify that all recovery sources are pruned.
This endpoint accepts an arbitrary file in the request body and
attempts to determine the structure. If successful it also
proposes mappings that could be used when indexing the file's
contents, and calculates simple statistics for each of the fields
that are useful in the data preparation step prior to configuring
machine learning jobs.
In an effort to encapsulate the different clients, the request

Watcher validates `action.auto_create_index` upon startup. If a user
specifies a pattern that does not contain watcher indices, it raises an
error message to include a list of three indices. However, the indices
are separated by a comma and a space which is not considered in parsing.
With this commit we change the error message string so it does not
contain the additional space thus making it more straightforward to copy
it to the configuration file.

Instead of passing DirectoryService which causes yet another dependency
on Store we can just pass in a Directory since we will just call
`DirectoryService#newDirectory()` on it anyway.
This change collapses all metrics aggregations classes into a single package `org.elasticsearch.aggregations.metrics`.
It also restricts the visibility of some classes (aggregators and factories) that should not be used outside of the package.

Some browsers (eg. Firefox) behave differently when presented with
multiple auth schemes in 'WWW-Authenticate' header. The expected
behavior is that browser select the most secure auth-scheme before
trying others, but Firefox selects the first presented auth scheme and
tries the next ones sequentially. As the browser interpretation is
something that we do not control, we can at least present the auth
schemes in most to least secure order as the server's preference.
This commit modifies the code to collect and sort the auth schemes
presented by most to least secure. The priority of the auth schemes is
fixed, the lower number denoting more secure auth-scheme.
The current order of schemes based on the ES supported auth-scheme is
[Negotiate, Bearer,Basic] and when we add future support for
other schemes we will need to update the code. If need be we will make
this configuration customizable in future.
Unit test to verify the WWW-Authenticate header values are sorted by
server preference as more secure to least secure auth schemes.
Tested with Firefox, Chrome, Internet Explorer 11.
Closes#32699
When we rollover and index we write the conditions of the rollover that
the old index met into the old index. Loading this index metadata
requires a working `NamedXContentRegistry` that has been populated with
parsers from the rollover infrastructure. We had a few loads that didn't
use a working `NamedXContentRegistry` and so would fail if they ever
encountered an index that had been rolled over. Here are the locations
of the loads and how I fixed them:
* IndexFolderUpgrader - removed entirely. It existed to support opening
indices made in Elasticsearch 2.x. Since we only need this change as far
back as 6.4.1 which will supports reading from indices created as far
back as 5.0.0 we should be good here.
* TransportNodesListGatewayStartedShards - wired the
`NamedXContentRegistry` into place.
* TransportNodesListShardStoreMetaData - wired the
`NamedXContentRegistry` into place.
* OldIndexUtils - removed entirely. It existed to support the zip based
index backwards compatibility tests which we've since replaced with code
that actually runs old versions of Elasticsearch.
In addition to fixing the actual problem I added full cluster restart
integration tests for rollover which would have caught this problem and
I added an extra assertion to IndexMetaData's deserialization code which
will trip if we try to deserialize and index's metadata without a fully
formed `NamedXContentRegistry`. It won't catch if use the *wrong*
`NamedXContentRegistry` but it is better than nothing.

This commit allows us to use different TranslogRecoveryRunner when
recovering an engine from its local translog. This change is a
prerequisite for the commit-based rollback PR.

Add missing aggregation functions
Enable documentation testing (was disabled by accident). While at it,
fix failing tests

Add ability to ignore a spec test (name should end with -Ignore)
The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
