Changed `rescore`s to `rescore` requests as an backtick followed by the s character appears to be interpreted as an apostrophe which then leads to an unbalanced backtick for the next code span in the remainder of the paragraph
Closes#25443
The primary shard uses the GlobalCheckPointTracker to track local checkpoint information of recovering and started replicas in order to calculate the global checkpoint. As the tracker is updated through recoveries as well, it is easier to reason about the tracker if we can ensure that there are no concurrent recovery attempts for the same target shard (which can happen in case of network disconnects).
When a replica shard increases its primary term under the mandate of a new primary, it should also update its global checkpoint; this gives us the guarantee that its global checkpoint is at least as high as the new primary and gives a starting point for the primary/replica resync.

We already have these tests in InternalAggregationTestCase to check random insertions into the response xContent so that we don't fail on future changes in the response format. This change adds the same to AggregationsTests and runs on a whole aggregations tree. Unfortunately we need to exclude many places in the xContent from random insertion, but I added a long comment trying to explaine those.
This commit marks a failing test as awaits fix. The test is failing due
to a primary shard not knowing its own local checkpoint in the global
checkpoint tracker after recovery. If such a shard becomes primary after
promotion, and is then subsequently relocated, it can lead to a
violation of an assertion that when the primary context is transferred
the knowledge of all in-sync local checkpoints is consistent with the
global checkpoint on the relocation target.

This commit removes the default path settings for data and logs. With
this change, we now ship the packages with these settings set in the
elasticsearch.yml configuration file rather than going through the
default.path.data and default.path.logs dance that we went through in
the past.

Today we load plugins reflectively, looking for constructors that
conform to specific signatures. This commit tightens the reflective
operations here, not allowing plugins to have ambiguous constructors.

This commit removes path.conf as a valid setting and replaces it with a
command-line flag for specifying a non-default path for configuration.

This commit removes an abstraction that was introduced when introducing
the primary context. As this abstraction is used in exactly one place,
we simply make that abstraction local to its usage so that we do not
accumulate yet another general abstraction with exactly one usage.

This commit updates some assertions in the primary context sealing test
after the restriction on updating allocation IDs from master and
updating global checkpoint on replica while sealed were removed.
* Introduce primary context
The target of a primary relocation is not aware of the state of the
replication group. In particular, it is not tracking in-sync and
initializing shards and their checkpoints. This means that after the
target shard is started, its knowledge of the replication group could
differ from that of the relocation source. In particular, this differing
view can lead to it computing a global checkpoint that moves backwards
after it becomes aware of the state of the entire replication
group. This commit addresses this issue by transferring a primary
context during relocation handoff.

You can continue a test started in a previous snippet by marking the
next snippet with `// TEST[continued]`. The trouble is, if you mark the
first snippet in a file with `// TEST[continued]` you'd get difficult
to predict behavior because you'd continue the test started in another
file. This will usually create a test that fails the build but it isn't
easy to track down what you did wrong. This commit catches this
scenario up front and fails the build with a useful error message.
Similarly, if you put `// TEST[continued]` directly after a
`// TESTSETUP` section then the docs tests will fail to run but the
error message did not point you to the `// TEST[continued]` snippet.
This commit catches this scenario up front as well and fails the build
with a useful error message.
This removes the remaining usage of `mapping.single_type` from the parent join
module and moves it's bwc test to the mixed cluster tests

While real secure settings (ie an ES keystore) cannot be merged
together, mocked secure settings can and need to be sometimes merged.
This commit adds a merge method to allow tests to merge together
multiple instances of secure settings.
This change removes the remaining explicitly specified `index.mapper.single_type`
settings from tests in order to allow the removal of the setting.
This is the already approved part of #25375 broken out to simplfiy reviews on
When Log4j 2 was introduced, we removed support for the system property
es.logger.prefix. Yet, some code was left behind. This commit removes
that dead code.

* Remove the setting from the yml tests and replace with tests using
`join` field. We can't use the setting in yml tests without lots of
backflips but we have `ReindexParentChildTests` for the coverage.
There weren't tests for `join` field with reindex before this. Adding
these tests discovered #25363.
* Remove the setting from `ReindexParentChildTests` and replace with
`index.version.created=V_5_6_0`. This test can be entirely removed
when legacy parent/child support is dropped from core.
* Port the yml tests that set _parent into integ tests so they
can set the index created version. These tests can be removed
when we drop support for _parent in core.
* Port a delete-by-query test for filtering based on type to an
`ESIntegTestCase` so it can use `index.version.created=5.6.0` to
setup documents of multiple types. This whole feature can be dropped
when we no longer support multiple types per index.

This change cleans up remaining tests to not use index.mapping.single_type=false
but instead where applicable use a single type or markt the index as created
with a pre 6.x version.
Yet, there is still on leftover in the client tests that needs special attention.

When JAVA_HOME is not set we try to detect the location of Java. If its
location contains a space, due to a lack of quoting we will be
unsuccessful in invoking Java. This commit adds the necessary quoting to
handle this case.
