First, some background: we have 15 different methods to get a logger in
Elasticsearch but they can be broken down into three broad categories
based on what information is provided when building the logger.
Just a class like:
```
private static final Logger logger = ESLoggerFactory.getLogger(ActionModule.class);
```
or:
```
protected final Logger logger = Loggers.getLogger(getClass());
```
The class and settings:
```
this.logger = Loggers.getLogger(getClass(), settings);
```
Or more information like:
```
Loggers.getLogger("index.store.deletes", settings, shardId)
```
The goal of the "class and settings" variant is to attach the node name
to the logger. Because we don't always have the settings available, we
often use the "just a class" variant and get loggers without node names
attached. There isn't any real consistency here. Some loggers get the
node name because it is convenient and some do not.
This change makes the node name available to all loggers all the time.
Almost. There are some caveats are testing that I'll get to. But in
*production* code the node name is node available to all loggers. This
means we can stop using the "class and settings" variants to fetch
loggers which was the real goal here, but a pleasant side effect is that
the ndoe name is now consitent on every log line and optional by editing
the logging pattern. This is all powered by setting the node name
statically on a logging formatter very early in initialization.
Now to tests: tests can't set the node name statically because
subclasses of `ESIntegTestCase` run many nodes in the same jvm, even in
the same class loader. Also, lots of tests don't run with a real node so
they don't *have* a node name at all. To support multiple nodes in the
same JVM tests suss out the node name from the thread name which works
surprisingly well and easy to test in a nice way. For those threads
that are not part of an `ESIntegTestCase` node we stick whatever useful
information we can get form the thread name in the place of the node
name. This allows us to keep the logger format consistent.
When using cross-cluster search through the high-level REST client, the cluster alias from each search hit was not parsed correctly. It would be part of the index field initially, but overridden just a few lines later once setting the shard target (in case we have enough info to build it from the response). In any case, getClusterAlias returns `null` which is a bug.
With this change we rather parse back clusterAliases from the index name, set its corresponding field and properly handle the two possible cases depending on whether we can or cannot build the shard target object.
The method for working out whether a polygon is clockwise or anticlockwise is
mostly correct but doesn't work in some rare cases such as the included test
case. This commit fixes that.
Rollover should not swap aliases when `is_write_index` is set to `true`.
Instead, both the new and old indices should have the rollover alias,
with the newly created index as the new write index
Updates Rollover to leverage the ability to preserve aliases and swap which is the write index.
Historically, Rollover would swap which index had the designated alias for writing documents against. This required users to keep a separate read-alias that enabled reading against both rolled over and newly created indices, whiles the write-alias was being re-assigned at every rollover.
With the ability for aliases to designate a write index, Rollover can be a bit more flexible with its use of aliases.
Updates include:
- Rollover validates that the target alias has a write index (the index that is being rolled over). This means that the restriction that aliases only point to one index is no longer necessary.
- Rollover explicitly (and atomically) swaps which index is the write-index by explicitly assigning the existing index to have `is_write_index: false` and have the newly created index have its rollover alias as `is_write_index: true`. This is only done when `is_write_index: true` on the write index. Default behavior of removing the alias from the rolled over index stays when `is_write_index` is not explicitly set
Relevant things that are staying the same:
- Rollover is rejected if there exist any templates that match the newly-created index and configure the rollover-alias
- I think this existed to prevent the situation where an alias pointed to two indices for a short while. Although this can technically be relaxed, the specific cases that are safe are really particular and difficult to reason, so leaving the broad restriction sounds good
* Ensure decryption related exceptions are handled
This commit ensures that all possible Exceptions in
KeyStoreWrapper#decrypt() are handled. More specifically, in the
case that a wrong password is used for secure settings, calling readX
on the DataInputStream that wraps the CipherInputStream can throw an
IOException. It also adds a test for loading a KeyStoreWrapper with
a wrong password.
Resolves#32411
Today when reading operation history in Lucene, we read all documents.
However, if indexing a document is aborted, IndexWriter will hard-delete
it; we, therefore, need to exclude that document from Lucene history.
This commit makes sure that we exclude aborted documents by using the
hard liveDocs of a SegmentReader if there are deletes.

[CI] Mute DocumentSubsetReaderTests testSearch
In rare cases it is possible that a nodes gets an instruction to replace a replica
shard that's in `POST_RECOVERY` with a new initializing primary with the same allocation id.
This can happen by batching cluster states that include the starting of the replica, with
closing of the indices, opening it up again and allocating the primary shard to the node in
question. The node should then clean it's initializing replica and replace it with a new
initializing primary.
I'm not sure whether the test I added really adds enough value as existing tests found this. The main reason I added is to allow for simpler reproduction and to double check I fixed it. I'm open to discuss if we should keep.
Closes#32308
`GetResult` and `SearchHit` have been adjusted to parse back the `_ignored` meta field whenever it gets printed out. Expanded the existing tests to make sure this is covered. Fixed also a small problem around highlighted fields in `SearchHitTests`.

Painless: Add method type to method. (#32441)
Due to the recent change in LUCENE-8263, we need to adjust the deletion
ration to between 10% to 33% to preserve the current behavior of the
test. However, we may need another refinement if soft-deletes is enabled
as the actual deletes are different because of delete tombstones.
This commit prefers to always execute forceMerge instead of adjusting
the deletion ratio so that this test can focus on testing docStats.
Closes#32449
Due to the recent change in LUCENE-8263, a merge can be triggered if the
deletion ration is higher than 33%. An in-progress merge can prevent a
synced-flush from issuing.
This commit avoids deletes by using different docIds.

Today it's possible to encounter an Index operation in Lucene whose
_source is disabled, and _recovery_source was pruned by the MergePolicy.
If it's the case, we create a Translog#Index without source and let the
caller validate it later. However, this approach is challenging for the
caller.
Deletes and No-Ops don't allow invoking "source()" method. The caller
has to make sure to call "source()" only on index operations. The
current implementation in CCR does not follow this and fail to replica
deletes or no-ops. Moreover, it's easier to reason if a Translog#Index
always has the source.
The main highlight is the removal of the reclaim_deletes_weight in the TieredMergePolicy.
The es setting index.merge.policy.reclaim_deletes_weight is deprecated in this commit and the value is ignored. The new merge policy setting setDeletesPctAllowed should be added in a follow up.
This commit changes the randomization to always create an index with a type.
It also adds a way to create a query shard context that maps to an index with
no type registered in order to explicitely test cases where there is no type.
* Using short script form normalized to a map that used 'inline' instead of 'source' so a short form processor definition like:
```
{
"script": "ctx.foo= 'bar'"
}
```
would always warn about the following deprecation:
```
#! Deprecation: Deprecated field [inline] used, expected [source]
```
In testSyncedFlushSkipOutOfSyncReplicas, we reindex the extra documents
to all shards including the out-of-sync replica. However, reindexing to
that replica can trigger merges (due to the new deletes) which cause the
synced-flush failed. This test starts failing after we aggressively
trigger merges segments with a large number of deletes in LUCENE-8263.
Removing some dead code or supressing warnings where apropriate. Most of the
time the variable tested for null is dereferenced earlier or never used before.
Today we allow plugins to add index store implementations yet we are not
doing this in our new way of managing plugins as pull versus push. That
is, today we still allow plugins to push index store providers via an on
index module call where they can turn around and add an index
store. Aside from being inconsistent with how we manage plugins today
where we would look to pull such implementations from plugins at node
creation time, it also means that we do not know at a top-level (for
example, in the indices service) which index stores are available. This
commit addresses this by adding a dedicated plugin type for index store
plugins, removing the index module hook for adding index stores, and by
aggregating these into the top-level of the indices service.
An upcoming [Lucene change](https://issues.apache.org/jira/browse/LUCENE-7976)
will make TieredMergePolicy respect the maximum merged segment size all the
time, meaning it will possibly not respect the `max_num_segments` parameter
anymore if the shard is larger than the maximum segment size.
This change makes sure that `max_num_segments` is respected for now in order
to give us time to think about how to integrate this change, and also to delay
it until 7.0 as this might be a big-enough change for us to wait for a new
major version.

This commit introduces "Application Privileges" to the X-Pack security
model.
Application Privileges are managed within Elasticsearch, and can be
tested with the _has_privileges API, but do not grant access to any
actions or resources within Elasticsearch. Their purpose is to allow
applications outside of Elasticsearch to represent and store their own
privileges model within Elasticsearch roles.
Access to manage application privileges is handled in a new way that
grants permission to specific application names only. This lays the
foundation for more OLS on cluster privileges, which is implemented by
allowing a cluster permission to inspect not just the action being
executed, but also the request to which the action is applied.
To support this, a "conditional cluster privilege" is introduced, which
is like the existing cluster privilege, except that it has a Predicate
over the request as well as over the action name.
Specifically, this adds
- GET/PUT/DELETE actions for defining application level privileges
- application privileges in role definitions
- application privileges in the has_privileges API
- changes to the cluster permission class to support checking of request
objects
- a new "global" element on role definition to provide cluster object
level security (only for manage application privileges)
- changes to `kibana_user`, `kibana_dashboard_only_user` and
`kibana_system` roles to use and manage application privileges

Adds a new single-value metrics aggregation that computes the weighted
average of numeric values that are extracted from the aggregated
documents. These values can be extracted from specific numeric
fields in the documents.
When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value. In contrast, weighted averages
scale each datapoint differently. The amount that each datapoint contributes
to the final value is extracted from the document, or provided by a script.
As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`
A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.

Currently we check that the queries that QueryStringQueryBuilder#toQuery returns
is one out of a list of many Lucene query classes. This list has extended a lot over time,
since QueryStringQueryBuilder can build all sort of queries. This makes the test hard to
maintain. The recent addition of alias fields which build a BlendedTermQuery show how
easy this test breaks. Also the current assertions doesn't add a lot in terms of catching
errors. This is why we decided to remove this check.
Closes#32234
