Currently when aggregating on an unmapped date field (e.g. using a
date_histogram) we don't preserve the aggregations `format` setting but instead
use the default format. This can lead to loosing the aggregations `format` when
aggregating over several indices where some of them contain unmapped date fields
and are encountered first in the reduce phase.
Related to #31760
Today the `composite` aggregation throws an error if a source targets an
unmapped field and `missing_bucket` is set to false. Documents without a
value for a source cannot produce any bucket if `missing_bucket` is not
activated so the error is a shortcut to say that the response will be empty.
However this is not consistent with the `terms` aggregation which accepts
unmapped field by default even if the response is also guaranteed to be empty.
This commit removes this restriction, if a source contains an unmapped field
we now return an empty response (no buckets).
Closes#35317
The current implementation of asyncBlockOperations() can be used to
execute some code once all indexing operations permits have been acquired,
then releases all permits immediately after the code execution. This
immediate release is not suitable for treatments that need to keep all
permits over multiple execution steps.
This commit adds a new asyncBlockOperations() that exposes a Releasable,
making it possible to acquire all permits and only release them all
when needed by closing the Releasable. The existing blockOperations()
method has been modified to delegate permit acquisition/releasing to this new
method.

If the underlying mount point for the JNA temporary directory is mounted
noexec on Linux, then the JVM will not be able to map the native code in
as executable. This will prevent JNA from executing and will prevent
Elasticsearch from being able to execute some functions that rely on
native code (e.g., memory locking, and installing system call
filters). We do not want to get into the business of catching exceptions
and parsing messages towards this because these exception messages can
change on us. We also do not want to jump through a lot of hoops to
check the underlying mount point for noexec. Instead, we will rely on
documentation to address this problem. This commit adds to the important
system configuration section of the docs that the JNA temporary
directory is not on a mount point with the noexec mount option.
Adjust list of dynamic index settings that should be replicated
and added a test that verifies whether builtin dynamic index settings
are classified as replicated or non replicated (whitelisted).
This commit uses the index settings version so that a follower can
replicate index settings changes as needed from the leader.

There is no longer a concept of non-global "realm settings". All realm
settings should be loaded from the node's settings using standard
Setting classes.
This change renames the "globalSettings" field and method to simply be
"settings".
The file realm has not supported custom filenames/locations since at
least 5.0, but this test still tried to configure them.
Remove all configuration of file locations, and cleaned up a few other
warnings and deprecations
The lookup vars under params (namely _fields and _source) were
inadvertently removed when scoring scripts were converted to using
script contexts. This commit adds them back, along with deprecation
warnings for those that should not be used.

The change here is to throw an `AssertionError` instead of `break;` to
allow the `assertBusy()` to continue to busy wait until the desired

Since it's still possible to shrink an index when replicas are unassigned, we
should not check that all copies are available when performing the shrink, since
we set the allocation requirement for a single node.

A CCR test failure shows that the approach in #34474 is flawed.
Restoring the LocalCheckpointTracker from an index commit can cause both
FollowingEngine and InternalEngine to incorrectly ignore some deletes.
Here is a small scenario illustrating the problem:
1. Delete doc with seq=1 => engine will add a delete tombstone to Lucene
2. Flush a commit consisting of only the delete tombstone
3. Index doc with seq=0 => engine will add that doc to Lucene but soft-deleted
4. Restart an engine with the commit (step 2); the engine will fill its
LocalCheckpointTracker with the delete tombstone in the commit
5. Replay the local translog in reverse order: index#0 then delete#1
6. When process index#0, an engine will add it into Lucene as a live doc
and advance the local checkpoint to 1 (seq#1 was restored from the
commit - step 4).
7. When process delete#1, an engine will skip it because seq_no=1 is
less than or equal to the local checkpoint.
We should have zero document after recovering from translog, but here we
have one.
Since all operations after the local checkpoint of the safe commit are
retained, we should find them if the look-up considers also soft-deleted
documents. This PR fills the disparity between the version map and the
local checkpoint tracker by taking soft-deleted documents into account
while resolving strategy for engine operations.

* [ILM] Check shard and relocation status in AllocationRoutedStep
This is a follow-up from #35161 where we now check for started and relocating
state in `AllocationRoutedStep`.
Resolves#35258
Today when a percolator query contains a date range then the query
analyzer extracts that range, so that at search time the `percolate` query
can exclude percolator queries efficiently that are never going to match.
The problem is that if 'now' is used it is evaluated at index time.
So the idea is to rewrite date ranges with 'now' to a match all query,
so that the query analyzer can't extract it and the `percolate` query
is then able to evaluate 'now' at query time.
This change adds a `frozen` engine that allows lazily open a directory reader
on a read-only shard. The engine wraps general purpose searchers in a LazyDirectoryReader
that also allows to release and reset the underlying index readers after any and before
secondary search phases.

Adds basic rolling upgrade tests to check that lifecycles are still recognizable between rolling cluster upgrades and managed indices stay managed.

Today we only apply `ingore_throttled` to expansions from wildcards,
date math expressions and aliases. Yet, this is tricky since we might
have resolved certain expressions in pre-filter steps like security.
It's more consistent to apply this logic to all expressions including
concrete indices.

Sometimes users are confused about whether they can use the Convert Processor
for changing an existing fields type to other types even if the existing one is already
ingested. This confusion is from the first line of description. Changing this and also
adding a some detail to the code snippet.
With the removal of SearchScript (#34730), an extraneous compile method
was left behind in PainlessScriptEngine. This change removes the method and
updates the tests that depend on it to use the main compile method which
gives better test coverage.
With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
Grammar's identifiers can be completely skipped from counting depths
as they just add another level to the tree and they are always children
of some other expression which gets counted.
Increased maximum depth from 100 to 200. After testing on production
configuration with -Xss1m, depths of at least 250 can be used, so being
conservative we put the limit lower.

The elasticsearch-croneval CLI tool uses local dates to display when
something gets triggered the next time. This is very confusing.
This commit ensures, that UTC and local timezone times will be written
out.
The output looks like this and contains localized dates for each trigger
date as well as for `now`.
Now is [Tue, 28 Aug 2018 17:23:51 +0000] in UTC, local time is [ᏔᎵᏁ, 28 ᎦᎶ 2018 12:23:51 -0500]
Here are the next 10 times this cron expression will trigger:
1. Mon, 2 Jan 2040 11:00:00 +0000

This also removes an old outstanding TODO to use the jopt parsing to
cast the count to an integer instead of doing it ourselves.
In order to start shard follow tasks, the resume follow api already
needs execute N requests to the elected master node.
The pause follow API is also a master node action, which would make
how both APIs execute more consistent.
This is related to #29023. Additionally at other points we have
discussed a preference for removing the need to unnecessarily block
threads for opening new node connections. This commit lays the groudwork
for this by opening connections asynchronously at the transport level.
We still block, however, this work will make it possible to eventually
remove all blocking on new connections out of the TransportService
and Transport.
