Working through a heap dump for an unrelated issue I found that we can easily rack up
tens of MBs of duplicate empty instances in some cases.
I moved to a static constructor to guard against that in all cases.
This is a follow-up to #57573. This commit combines coordinating and
primary bytes under the same "write" bucket. Double accounting is
prevented by only accounting the bytes at either the reroute phase or
the primary phase. TransportBulkAction calls execute directly, so the
operations handler is skipped and the bytes are not double accounted.
Since #55785, exists queries rewrite to MatchNoneQueryBuilder when the field is unmapped.
This change also introduced a bug in the `query_string` query, using an unmapped field
like `_exists_:foo` throws an exception if the field is unmapped. This commit avoids the
exception if the query is built outside of an `ExistsQueryBuilder`.
Closes#58737
An old translog header does not have a checksum. If we flip the header
version of an empty translog to the older version, then we won't detect
that corruption, and translog will be considered clean as before.
Closes#58671
A regression in the mapping code led to geo_shape no longer supporting
array-valued fields. This commit fixes this support and adds an integration
test to make sure this problem does not return!
Ingest script processors were changed to eagerly compile their scripts
when the ingest pipeline is saved, but conditional scripts were missed.
This commit adds eager compilation to ingest conditional scripts, which
will help surface errors before runtime, as well as adds tests for each
case we might encounter between inline and stored script compilation
failures.

This commit adds an integration test that component templates used to form a composite template can
still be updated after a cluster restart.
In #58643 an issue arose where mappings were causing problems because of the way we unwrap `_doc` in
template mappings. This was also related to the mappings being merged manually rather than using the
`MapperService` to do the merging. #58643 was fixed in 7.9 and master with the #58521 change, since
mappings now are read and digested by the actual mapper service.
This test passes for 7.x and master, and I intend to open a separate PR including this test for
7.8.1 along with a bug fix for #58643. This test is to ensure we don't have any regression in the
future.
The refactoring in #57666 inadvertently enabled norms on two of the percolator subfields,
leading to an increase in memory usage. This commit disables norms on these fields again.
The `date_histogram` aggregation had an optimization where it'd rewrite
`time_zones` who's offset from UTC is fixed across the entire index.
This rewrite is no longer needed after #56371 because we can tell that a
time zone is fixed lower down in the aggregation. So this removes it.
This prohibits the use of a custom _routing when the index/bulk requests are targetting a data stream.
Using a custom _routing when targetting a backing index is still permitted.

Date processor was incorrectly parsing week based dates because when a
weekbased year was provided ingest module was thinking year was not
on a date and was trying to applying the logic for dd/MM type of
dates.
Date Processor is also allowing users to specify locale parameter. It
should be taken into account when parsing dates - currently only used
for formatting. If someone specifies 'en-us' locale, then calendar data
rules for that locale should be used.
The exception is iso8601 format. If someone is using that format,
then locale should not override calendar data rules.

The read-only-allow-delete block is not really under the user's control
since Elasticsearch adds/removes it automatically. This commit removes
support for it from the new API for adding blocks to indices that was
introduced in #58094.
Backport of #58231 to 7.x branch.
Change update index setting and put mapping api
to execute on all backing indices if data stream is targeted.

Restoring from a snapshot (which is a particular form of recovery) does not currently take recovery throttling into account
(i.e. the `indices.recovery.max_bytes_per_sec` setting). While restores are subject to their own throttling (repository
setting `max_restore_bytes_per_sec`), this repository setting does not allow for values to be configured differently on a
per-node basis. As restores are very similar in nature to peer recoveries (streaming bytes to the node), it makes sense to
configure throttling in a single place.
The `max_restore_bytes_per_sec` setting is also changed to default to unlimited now, whereas previously it was set to
`40mb`, which is the current default of `indices.recovery.max_bytes_per_sec`). This means that no behavioral change
will be observed by clusters where the recovery and restore settings were not adapted.

Today the disk-based shard allocator accounts for incoming shards by
subtracting the estimated size of the incoming shard from the free space on the
node. This is an overly conservative estimate if the incoming shard has almost
finished its recovery since in that case it is already consuming most of the
disk space it needs.
This change adds to the shard stats a measure of how much larger each store is
expected to grow, computed from the ongoing recovery, and uses this to account
for the disk usage of incoming shards more accurately.
Backport of #58029 to 7.x
* Picky picky
* Missing type
Adds an explicit check to `variable_width_histogram` to stop it from
trying to collect from many buckets because it can't. I tried to make it
do so but that is more than an afternoon's project, sadly. So for now we
just disallow it.

Mapping updates that originate from indexing a document with unmapped fields will use this new action
instead of the current put mapping action. This way on the security side, authorization logic
can easily determine whether a mapping update is automatically generated or a mapping update originates
from the put mapping api.
The new auto put mapping action is only used if all nodes are on the version that supports it.
This PR implements recursive mapping merging for composable index templates.
When creating an index, we perform the following:
* Add each component template mapping in order, merging each one in after the
last.
* Merge in the index template mappings (if present).
* Merge in the mappings on the index request itself (if present).
Some principles:
* All 'structural' changes are disallowed (but everything else is fine). An
object mapper can never be changed between `type: object` and `type: nested`. A
field mapper can never be changed to an object mapper, and vice versa.
* Generally, each section is merged recursively. This includes `object`
mappings, as well as root options like `dynamic_templates` and `meta`. Once we
reach 'leaf components' like field definitions, they always overwrite an
existing one instead of being merged.
Relates to #53101.
* Replace compile configuration usage with api (#58451)
- Use java-library instead of plugin to allow api configuration usage
- Remove explicit references to runtime configurations in dependency declarations
- Make test runtime classpath input for testing convention
- required as java library will by default not have build jar file
- jar file is now explicit input of the task and gradle will ensure its properly build
* Fix compile usages in 7.x branch
In the unlikely corner case of deleting a relocation (hence `WAITING`) primary shard's
index during a partial snapshot, we would throw an NPE when checking if there's any external
changes to process.
Adds an API for putting an index block in place, which also ensures for write blocks that, once successfully returning to
the user, all shards of the index are properly accounting for the block, for example that all in-flight writes to an index have
been completed after adding the write block.
This API allows coordinating more complex workflows, where it is crucial that an index is no longer receiving writes after
the API completes, useful for example when marking an index as read-only during an upgrade in order to reindex its
documents.
Only snapshot datastreams that are recorded in `SnapshotInfo` and clean those
that aren't from the snapshotted metadata.
Do not restore all datastreams by default when restoring global metadata, use the same
mechanics used for indices here.
Closes#58544
When restoring a global metadata snapshot we were overwriting the correctly
adjusted data streams in the metadata when looping over all custom values.
Closes#58496
The remote_monitoring_user user needs to access the enrich stats API.
But the request is denied because the API is categorized under admin.
The correct privilege should be monitor.
Java 9 removed pathname canonicalization, which means that we need to
add permissions for the path and also the real path when adding file
permissions. Since master requires a minimum runtime of JDK 11, we no
longer need conditional logic here to apply this pathname
canonicalization with our bares hands. This commit removes that
conditional pathname canonicalization.

`descendsFromBucketAggregator` was important before we removed
`asMultiBucketAggregator` but now that it is gone
`collectsFromSingleBucket` is good enough.

Today SparseFileTracker allows to wait for a range to become available
before executing a given listener. In the case of searchable snapshot,
we'd like to be able to wait for a large range to be filled (ie, downloaded
and written to disk) while being able to execute the listener as soon as
a smaller range is available.
This pull request is an extract from #58164 which introduces a
ProgressListenableActionFuture that is used internally by
SparseFileTracker. The progressive listenable future allows to register
listeners attached to SparseFileTracker.Gap so that they are executed
once the Gap is completed (with success or failure) or as soon as the
Gap progress reaches a given progress value. This progress value is
defined when the tracker.waitForRange() method is called; this method
has been modified to accept a range and another listener's range to
operate on.

Minor bugs/inconsistencies:
If a shard hasn't changed at all we were reporting `0` for total size and total file count
while it was ongoing.
If a data node restarts/drops out during snapshot creation the fallback logic did not load the correct statistic from the repository but just created a status with `0` counts from the snapshot state in the CS. Added a fallback to reading from the repository in this case.
Fixes two bugs introduced by #57627:
1. We were not properly letting go of memory from the request breaker
when the aggregation finished.
2. We no longer supported totally arbitrary stuff produced by the init
script because we *assumed* that it'd be ok to run the script once
and clone its results. Sadly, cloning can't clone *anything* that the
init script can make, like `String` arrays. This runs the init script
once for every new bucket so we don't need to clone.
If we failed over while the data nodes were doing their work
we would never resolve the listener and leak it.
This change fails all listeners if master fails over.
Rather than let ExtensiblePlugins know extending plugins' classloaders,
we now pass along an explicit ExtensionLoader that loads the extensions
asked for. Extensions constructed that way can optionally receive their
own Plugin instance in the constructor.
