ShardId already implements Writeable so there is no need for it to implement Streamable too. Also the readShardId static method can be

* Remove IndexShard dependency from Repository
In order to simplify repository testing especially for BlobStoreRepository
it's important to remove the dependency on IndexShard and reduce it to
Store and MapperService (in the snapshot case). This significantly reduces
the dependcy footprint for Repository and allows unittesting without starting
nodes or instantiate entire shard instances. This change deprecates the old
method signatures and adds a unittest for FileRepository to show the advantage
of this change.
In addition, the unittesting surfaced a bug where the internal file names that
are private to the repository were used in the recovery stats instead of the
target file names which makes it impossible to relate to the actual lucene files
in the recovery stats.

rp.client_secret is a required secure setting. Make sure we fail with
a SettingsException and a clear, actionable message when building
the realm, if the setting is missing.
Enhance the handling of merging the claims sets of the
ID Token and the UserInfo response. JsonObject#merge would throw a
runtime exception when attempting to merge two objects with the
same key and different values. This could happen for an OP that
returns different vales for the same claim in the ID Token and the
UserInfo response ( Google does that for profile claim ).
If a claim is contained in both sets, we attempt to merge the
values if they are objects or arrays, otherwise the ID Token claim
value takes presedence and overwrites the userinfo response.
This adds the node name where we fail to start a process via the native
controller to facilitate debugging as otherwise it might not be known
to which node the job was allocated.
Moves the test infrastructure away from using node.max_local_storage_nodes, allowing us in a
follow-up PR to deprecate this setting in 7.x and to remove it in 8.0.
This also changes the behavior of InternalTestCluster so that starting up nodes will not automatically
reuse data folders of previously stopped nodes. If this behavior is desired, it needs to be explicitly
done by passing the data path from the stopped node to the new node that is started.
SHA256 was recently added to the Hasher class in order to be used
in the TokenService. A few tests were still using values() to get
the available algorithms from the Enum and it could happen that
SHA256 would be picked up by these.
This change adds an extra convenience method
(Hasher#getAvailableAlgoCacheHash) and enures that only this and
Hasher#getAvailableAlgoStoredHash are used for getting the list of
available password hashing algorithms in our tests.
This performs a simple restart test to move a basic licensed
cluster from no security (the default) to security & transport TLS
enabled.

Rollup jobs can define how long they should wait before rolling up new documents.
However if the delay is smaller or if it's not a multiple of the rollup interval
the job can create incomplete buckets because the max boundary for a job is computed
from the time when the job started rounded to the interval minus the delay. This change
fixes this computation by applying the delay substraction before the rounding in order to ensure
that we never create a boundary that falls in a middle of a bucket.
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
This commit changes how access tokens and refresh tokens are stored
in the tokens index.
Access token values are now hashed before being stored in the id
field of the `user_token` and before becoming part of the token
document id. Refresh token values are hashed before being stored
in the token field of the `refresh_token`. The tokens are hashed
without a salt value since these are v4 UUID values that have
enough entropy themselves. Both rainbow table attacks and offline
brute force attacks are impractical.
As a side effect of this change and in order to support multiple
concurrent refreshes as introduced in #39631, upon refreshing an
<access token, refresh token> pair, the superseding access token
and refresh tokens values are stored in the superseded token doc,
encrypted with a key that is derived from the superseded refresh
token. As such, subsequent requests to refresh the same token in
the predefined time window will return the same superseding access
token and refresh token values, without hitting the tokens index
(as this only stores hashes of the token values). AES in GCM
mode is used for encrypting the token values and the key
derivation from the superseded refresh token uses a small number
of iterations as it needs to be quick.
For backwards compatibility reasons, the new behavior is only
enabled when all nodes in a cluster are in the required version
so that old nodes can cope with the token values in a mixed
cluster during a rolling upgrade.
This commit updates the default ciphers and TLS protocols that are used
when the runtime JDK supports them. New cipher support has been
introduced in JDK 11 and 12 along with performance fixes for AES GCM.
The ciphers are ordered with PFS ciphers being most preferred, then
AEAD ciphers, and finally those with mainstream hardware support. When
available stronger encryption is preferred for a given cipher.
This is a backport of #41385 and #41808. There are known JDK bugs with
TLSv1.3 that have been fixed in various versions. These are:
1. The JDK's bundled HttpsServer will endless loop under JDK11 and JDK
12.0 (Fixed in 12.0.1) based on the way the Apache HttpClient performs
a close (half close).
2. In all versions of JDK 11 and 12, the HttpsServer will endless loop
when certificates are not trusted or another handshake error occurs. An
email has been sent to the openjdk security-dev list and #38646 is open
to track this.
3. In JDK 11.0.2 and prior there is a race condition with session
resumption that leads to handshake errors when multiple concurrent
handshakes are going on between the same client and server. This bug
does not appear when client authentication is in use. This is
JDK-8213202, which was fixed in 11.0.3 and 12.0.
4. In JDK 11.0.2 and prior there is a bug where resumed TLS sessions do
not retain peer certificate information. This is JDK-8212885.
The way these issues are addressed is that the current java version is
checked and used to determine the supported protocols for tests that
provoke these issues.

Improve the hard_limit memory audit message by reporting how many bytes
over the configured memory limit the job was at the point of the last
allocation failure.
Previously the model memory usage was reported, however this was
inaccurate and hence of limited use - primarily because the total
memory used by the model can decrease significantly after the models
status is changed to hard_limit but before the model size stats are
reported from autodetect to ES.
While this PR contains the changes to the format of the hard_limit audit
message it is dependent on modifications to the ml-cpp backend to
send additional data fields in the model size stats message. These
changes will follow in a subsequent PR. It is worth noting that this PR
must be merged prior to the ml-cpp one, to keep CI tests happy.
Due to a bug in JTS WKT parser, JTS cannot parse most of WKT shapes if
the shape type is written in the lower case. For examples `point (1 2)`
is causing JTS inside H2GIS to fail on tr-TR locale as a result of
case-insensitive comparison.
This change replaces the extremely unfriendly message
"Number of messages analyzed must be positive" in the
case where the sample lines were incorrectly grouped
into just one message to an error that more helpfully
explains the likely root cause of the problem.
The migrate tool was added when the native realm was created, to aid
users in converting from file realms that were per node, into the
cluster managed native realm. While this tool was useful at the time,

deprecates the tool, to be removed in a followup for 8.0.
Interval * integer number is a valid operation which previously was
only supported for foldables (literals) and not when a field was
involved. That was because:
1. There was no common type returned for that combination
2. The `BinaryArithmeticOperation` was permitting the multiplication
(called by fold()) but the BinaryArithmeticProcessor didn't allow it
Moreover the error message for invalid arithmetic operations was wrong
because of the issue with the overloading methods of
`LoggerMessageFormat.format`.

If a basic license enables security, then we should also enforce TLS
on the transport interface.
This was already the case for Standard/Gold/Platinum licenses.
For Basic, security defaults to disabled, so some of the process
around checking whether security is actuallY enabled is more complex
now that we need to account for basic licenses.
Adds an initial limited implementations of geo features to SQL. This implementation is based on the [OpenGIS® Implementation Standard for Geographic information - Simple feature access](http://www.opengeospatial.org/standards/sfs), which is the current standard for GIS system implementation. This effort is concentrate on SQL option AKA ISO 19125-2.
Queries that are supported as a result of this initial implementation
Metadata commands
- `DESCRIBE table` - returns the correct column types `GEOMETRY` for geo shapes and geo points.
- `SHOW FUNCTIONS` - returns a list that includes supported `ST_` functions
- `SYS TYPES` and `SYS COLUMNS` display correct types `GEO_SHAPE` and `GEO_POINT` for geo shapes and geo points accordingly.
Returning geoshapes and geopoints from elasticsearch
- `SELECT geom FROM table` - returns the geoshapes and geo_points as libs/geo objects in JDBC or as WKT strings in console.
- `SELECT ST_AsWKT(geom) FROM table;` and `SELECT ST_AsText(geom) FROM table;`- returns the geoshapes ang geopoints in their WKT representation;
Using geopoints to elasticsearch
- The following functions will be supported for geopoints in queries, sorting and aggregations: `ST_GeomFromText`, `ST_X`, `ST_Y`, `ST_Z`, `ST_GeometryType`, and `ST_Distance`. In most cases when used in queries, sorting and aggregations, these function are translated into script. These functions can be used in the SELECT clause for both geopoints and geoshapes.
- `SELECT * FROM table WHERE ST_Distance(ST_GeomFromText(POINT(1 2), point) < 10;` - returns all records for which `point` is located within 10m from the `POINT(1 2)`. In this case the WHERE clause is translated into a range query.
Limitations:
Geoshapes cannot be used in queries, sorting and aggregations as part of this initial effort. In order to fully take advantage of geoshapes we would need to have access to geoshape doc values, which is coming in #37206. `ST_Z` cannot be used on geopoints in queries, sorting and aggregations since we don't store altitude in geo_point doc values.

The CircuitBreaker was introduced as means of preventing a
`StackOverflowException` during the build of the AST by the parser.
The ANTLR4 grammar causes a weird behaviour for a Parser Listener.
The `enterEveryRule()` method is often called with a different parsing
context than the respective `exitEveryRule()`. This makes it difficult
to keep track of the tree's depth, and a custom Map was used as an
attempt of matching the contextes as they are encounter during `enter`
and during `exit` of the rules.
This approach had 2 important drawbacks:
1. It's hard to maintain this custom Map as the grammar changes.
2. The CircuitBreaker could often lead to false positives which caused
valid queries to return an Exception and prevent them from executing.
So, this removes completely the CircuitBreaker which is replaced be
a simple handling of the `StackOverflowException`

Because realms are configured at node startup, but license levels can
change dynamically, it is possible to have a running node that has a
particular realm type configured, but that realm is not permitted under
the current license.
In this case the realm is silently ignored during authentication.
This commit adds a warning in the elasticsearch logs if authentication
fails, and there are realms that have been skipped due to licensing.
This message is not intended to imply that the realms could (or would)
have successfully authenticated the user, but they may help reduce
confusion about why authentication failed if the caller was expecting
the authentication to be handled by a particular realm that is in fact
unlicensed.

This is related to #27260. Currently we have a single read buffer that

our TLS work to support reading similar to the plaintext case. The data
will be copied to a (potentially) recycled TLS packet-sized buffer for
interaction with the SSLEngine.

This commit is a refactoring of how we filter addresses on
interfaces. In particular, we refactor all of these methods into a
common private method. We also change the order of logic to first check
if an address matches our filter and then check if the interface is
up. This is to possibly avoid problems we are seeing where devices are
flapping up and down while we are checking for loopback addresses. We do
not expect the loopback device to flap up and down so by reversing the
logic here we avoid that problem on CI machines. Finally, we expand the
error message when this does occur so that we know which device is
flapping.
This is related to #27260. Currently there is a setting
http.read_timeout that allows users to define a read timeout for the

no requests received since the last run and there are no inflight

* [ML] Refactor NativeStorageProvider to enable reuse
Moves `NativeStorageProvider` as a machine learning component

* Adding nativeStorageProvider as component
Since `TransportForecastJobAction` is expected to get injected a `NativeStorageProvider` class, we need to make sure that it is a constructed component, as it does not have a zero parametered, public ctor.
This is modelled on the qa test for TLS on basic.
It starts a cluster on basic with security & performs a number of
security related checks.
It also performs those same checks on a trial license.
This adds support for using security on a basic license.
It includes:
- AllowedRealmType.NATIVE realms (reserved, native, file)
- Roles / RBAC
- TLS (already supported)
It does not support:
- Audit
- IP filters
- Token Service & API Keys
- Advanced realms (AD, LDAP, SAML, etc)
- Advanced roles (DLS, FLS)
- Pluggable security
As with trial licences, security is disabled by default.
This commit does not include any new automated tests, but existing tests have been updated.
This commit introduces the `.security-tokens` and `.security-tokens-7`
alias-index pair. Because index snapshotting is at the index level granularity
(ie you cannot snapshot a subset of an index) snapshoting .`security` had
the undesirable effect of storing ephemeral security tokens. The changes
herein address this issue by moving tokens "seamlessly" (without user
intervention) to another index, so that a "Security Backup" (ie snapshot of
`.security`) would not be bloated by ephemeral data.
Today we allow adding entries from a file or from a string, yet we
internally maintain this distinction such that if you try to add a value
from a file for a setting that expects a string or add a value from a
string for a setting that expects a file, you will have a bad time. This
causes a pain for operators such that for each setting they need to know
this difference. Yet, we do not need to maintain this distinction
internally as they are bytes after all. This commit removes that
distinction and includes logic to upgrade legacy keystores.
This commit removes the usage of the `BulkProcessor` to write history documents
and delete triggered watches on a `EsRejectedExecutionException`. Since the
exception could be handled on the write thread, the write thread can be blocked
waiting on watcher threads (due to a synchronous method). This is problematic
since those watcher threads can be blocked waiting on write threads.
This commit also moves the handling of the exception to the generic threadpool
to avoid submitting write requests from the write thread pool.

Today we choose to initialize max_seq_no_of_updates on primaries only so
we can deal with a situation where a primary is on an old node (before
6.5) which does not have MUS while replicas on new nodes (6.5+).
However, this strategy is quite complex and can lead to bugs (for
example #40249) since we have to assign a correct value (not too low) to
MSU in all possible situations (before recovering from translog,
restoring history on promotion, and handing off relocation).
Fortunately, we don't have to deal with this BWC in 7.0+ since all nodes
in the cluster should have MSU. This change simplifies the
initialization of MSU by always assigning it a correct value in the
constructor of Engine regardless of whether it's a replica or primary.

This is related to #27260. Currently for the SSLDriver we allocate a
dedicated network write buffer and encrypt the data into that buffer one
buffer at a time. This requires constantly switching between encrypting
and flushing. This commit adds a dedicated outbound buffer for SSL
operations that will internally allocate new packet sized buffers as
they are need (for writing encrypted data). This allows us to totally
encrypt an operation before writing it to the network. Eventually it can
be hooked up to buffer recycling.
This commit also backports the following commit:
Handle WRAP ops during SSL read
It is possible that a WRAP operation can occur while decrypting
handshake data in TLS 1.3. The SSLDriver does not currently handle this
well as it does not have access to the outbound buffer during read call.
This commit moves the buffer into the Driver to fix this issue. Data
wrapped during a read call will be queued for writing after the read
call is complete.
Motivated by slow snapshot deletes reported in e.g. #39656 and the fact that these likely are a contributing factor to repositories accumulating stale files over time when deletes fail to finish in time and are interrupted before they can complete.
* Makes snapshot deletion async and parallelizes some steps of the delete process that can be safely run concurrently via the snapshot thread poll
* I did not take the biggest potential speedup step here and parallelize the shard file deletion because that's probably better handled by moving to bulk deletes where possible (and can still be parallelized via the snapshot pool where it isn't). Also, I wanted to keep the size of the PR manageable.
* See https://github.com/elastic/elasticsearch/pull/39656#issuecomment-470492106
* Also, as a side effect this gives the `SnapshotResiliencyTests` a little more coverage for master failover scenarios (since parallel access to a blob store repository during deletes is now possible since a delete isn't a single task anymore).
* By adding a `ThreadPool` reference to the repository this also lays the groundwork to parallelizing shard snapshot uploads to improve the situation reported in #39657

Today the `_field_caps` API returns the list of indices where a field
is present only if this field has different types within the requested indices.
However if the request is an index pattern (or an alias, or both...) there
is no way to infer the indices if the response contains only fields that have
the same type in all indices. This commit changes the response to always return
the list of indices in the response. It also adds a way to retrieve unmapped field
in a specific section per field called `unmapped`. This section is created for each field
that is present in some indices but not all if the parameter `include_unmapped` is set to
true in the request (defaults to false).

instead use the `ExpressionModel#NULL_PREDICATE` for the DN field, just like

The SimplifyConditional rule is removing NULL literals from those
functions to simplify their evaluation. This happens in the Optimizer
and a new instance of the conditional function is generated. Previously,
the dataType was not set properly (defaulted to DataType.NULL) for

it resulted in returning always null.
E.g.:
SELECT COALESCE(null, 'foo', null, 'bar')
COALESCE(null, 'foo', null, 'bar')
-----------------
null
This issue was not visible before because the tests always used an alias
for the conditional function which caused the resolveType() to be
called which sets the dataType properly.
E.g.:
SELECT COALESCE(null, 'foo', null, 'bar') as c
c

The date_histogram internally converts obsolete timezones (such as
"Canada/Mountain") into their modern equivalent ("America/Edmonton").
But rollup just stored the TZ as provided by the user.
When checking the TZ for query validation we used a string comparison,
which would fail due to the date_histo's upgrading behavior.
Instead, we should convert both to a TimeZone object and check if their
rules are compatible.
CURRENT_DATE/CURRENT_TIME/CURRENT_TIMESTAMP can be used as SQL keywords
(without parentheses) and therefore there is a special rule in the
grammar to accommodate this.
Previously, this rule was also catching the parenthesised version of those functions too,
not allowing the {fn <functionName>()} to be used. E.g.:
{fn current_time(2)} or {fn current_timestamp()}
Now, the grammar rule catches only the keyword versions and all the parenthesised
versions go through the normal function resolution. As a consequence the validation
of the precision is moved from the parser lever (ExpressionBuilder) to the function

When the same alias points to multiple indices we can write to only one index
with `is_write_index` value `true`. The special handling in case of the put
mapping request(to resolve authorized indices) has a check on indices size
for a concrete index. If multiple indices existed then it marked the request
as unauthorized.
The check has been modified to consider write index flag and only when the
requested index matches with the one with write index alias, the alias is considered
for authorization.
Closes#40831
In `TransportRolloverAction` before doing rollover we resolve
source index name (write index) from the alias in the rollover request.
Before evaluating the conditions and executing rollover action, we
retrieve stats, but to do so we used the source index name
resolved from the alias instead of alias from the index.
This fails when the user is assigned a role with index privilege on the
alias instead of the concrete index. This commit fixes this by using
the alias from the request.
After this change, verified that when we retrieve all the stats (including write + read indexes)
we are considering only source index.
Closes#40771
When specifying a limit over an agg sorting, the limit will be pushed
down to the grouping which affects the custom sorting. This commit fixes

Traditionally we have [recommended](https://www.elastic.co/guide/en/beats/filebeat/current/monitoring.html) that Beats send their monitoring data to the **production** Elasticsearch cluster. Beats do this by calling the `POST _monitoring/bulk` API. When Security is enabled this API call requires the `cluster:admin/xpack/monitoring/bulk` privilege. The built-in `beats_system` role has this privilege.
[Going forward](https://github.com/elastic/beats/pull/9260), Beats will be able to send their monitoring data directly to the **monitoring** Elasticsearch cluster. Beats will do this by calling the regular `POST _bulk` API. When Security is enabled this API call requires the `indices:data/write/bulk` privilege. Further, the call has to be able to create any indices that don't exist.
This PR expands the built-in `beats_system` role's privileges. Specifically, it adds index-level `write` and `create_index` privileges for `.monitoring-beats-*` indices.
This will allow Beats users to continue using the `beats_system` role for the new direct monitoring route when Security is enabled.
Usage of the ILM Move to Step API can result in some very odd
situations, and for diagnosing problems arising from these situations it
would be nice to have a record of when this API was called with what
parameters.
Also, adds a dedicated logger for TransportMoveToStepAction,
rather than using the (deprecated) inherited one.
This commit removes xpack dependencies of many xpack qa modules.
(for some qa modules this will require some more work)
The reason behind this change is that qa rest modules should not depend
on the x-pack plugins, because the plugins are an implementation detail and
the tests should only know about the rest interface and qa cluster that is
being tested.
Also some qa modules rely on xpack plugins and hlrc (which is a valid
dependency for rest qa tests) creates a cyclic dependency and this is
something that we should avoid. Also Eclipse can't handle gradle cyclic
dependencies (see #41064).
* don't copy xpack-core's plugin property into the test resource of qa
modules. Otherwise installing security manager fails, because it tries
to find the XPackPlugin class.
Values higher than 100% are now allowed to accommodate use
cases where swapping has been determined to be acceptable.
Anomaly detector jobs only use their full model memory
during background persistence, and this is deliberately
staggered, so with large numbers of jobs few will generally
be persisting state at the same time. Settings higher than
available memory are only recommended for OEM type
situations where a wrapper tightly controls the types of
jobs that can be created, and each job alone is considerably
smaller than what each node can handle.
This commit adds an OpenID Connect authentication realm to
elasticsearch. Elasticsearch (with the assistance of kibana or
another web component) acts as an OpenID Connect Relying
Party and supports the Authorization Code Grant and Implicit
flows as described in http://ela.st/oidc-spec. It adds support
for consuming and verifying signed ID Tokens, both RP
initiated and 3rd party initiated Single Sign on and RP
initiated signle logout.
It also adds an OpenID Connect Provider in the idp-fixture to
be used for the associated integration tests.
This is a backport of #40674
This change adds either ToXContentObject or ToXContentFragment to classes
directly implementing ToXContent currently. This helps in reasoning about
whether those implementations output full xcontent object or just fragments.

It is possible for the watches tracked by ScheduleTriggerEngineMock to
get out of sync with the Watches in the ScheduleTriggerEngine
production code, which can lead to watches failing to run.
This commit:
1. Changes TimeWarp to try to run the watch on all schedulers, rather than stopping after one which claims to have the watch registered. This reduces the impact of desynchronization between the mocking code and the backing production code.
2. Makes ScheduleTriggerEngineMock respect pauses of execution again. This is necessary to prevent duplicate watch invocations due to the above change.
3. Tweaks how watches are registered in ScheduleTriggerEngineMock to prevent race conditions due to concurrent modification.
4. Tweaks WatcherConcreteIndexTests to use TimeWarp instead of waiting for watches to be triggered, as TimeWarp is more reliable and accomplishes the same goal.
For pattern "n:localhost" PatternRule#isLocalhost() matches
any local address, loopback address.
[Note: I think for "localhost" this should not consider IP address
as a match when they are bound to network interfaces. It should just
be loopback address check unless the intent is to match all local addresses.
This class is adopted from Netty3 and I am not sure if this is intended
behavior or maybe I am missing something]
For now I have fixed this assuming the PatternRule#isLocalhost check is
correct by avoiding use of local address to check address denied.

* Use environment settings instead of state settings for Watcher config
Prior to this we used the settings from cluster state to see whether ILM was
enabled of disabled, however, these settings don't accurately reflect the
`xpack.ilm.enabled` setting in `elasticsearch.yml`.
This commit changes to using the `Environment` settings, which correctly reflect
the ILM enabled setting.
Resolves#41042
ILM poll intervals of less than 1 second will not be allowed, so add a
deprecation check for that.
Even though I'm pretty sure zero production clusters will do this, it's
best to be thorough.
Fixes some documentation urls in the rest-api-spec. Some of these URLs
pointed to 404s and a few others pointed to deprecated documentation
when we have better documentation now. I'm not consistent about `master`
vs `current` because we're not consistent in other places and I think we
should solve all of those at once with something a little more
automatic.
disallow partial results in rollup and data frame, after this change the client throws an error directly
replacing the previous runtime exception thrown, allowing better error handling in implementations.
This is a dependency of #39504
Motivation:
By refactoring `TransportShardBulkAction#shardOperationOnPrimary` to async, we enable using `DeterministicTaskQueue` based tests to run indexing operations. This was previously impossible since we were blocking on the `write` thread until the `update` thread finished the mapping update.
With this change, the mapping update will trigger a new task in the `write` queue instead.
This change significantly enhances the amount of coverage we get from `SnapshotResiliencyTests` (and other potential future tests) when it comes to tracking down concurrency issues with distributed state machines.
The logical change is effectively all in `TransportShardBulkAction`, the rest of the changes is then simply mechanically moving the caller code and tests to being async and passing the `ActionListener` down.
Since the move to async would've added more parameters to the `private static` steps in this logic, I decided to inline and dry up (between delete and update) the logic as much as I could instead of passing the listener + wait-consumer down through all of them.
* moved hlrc parsing tests from xpack to hlrc module and removed dependency on hlrc from xpack core
* deprecated old base test class
* added deprecated jdoc tag
* split test between xpack-core part and hlrc part
* added lang-mustache test dependency, this previously came in via
hlrc dependency.
* added hlrc dependency on a qa module
* duplicated ClusterPrivilegeName class in xpack-core, since x-pack
core no longer has a dependency on hlrc.
* replace ClusterPrivilegeName usages with string literals
* moved tests to dedicated to hlrc packages in order to remove Hlrc part from the name and make sure to use imports instead of full qualified class where possible
* remove ESTestCase. from method invocation and use method directly,
because these tests indirectly extend from ESTestCase
When monitoring exporters are all disabled, which must be done
explicitly, _and_ monitoring collection is enabled, then
any call to `_xpack/monitoring/_bulk` will create a task that
never closes _and_ ES collection will stop happening because
a semaphore is never marked as completed.
This also simplifies the async `ExportBulk` code by removing the
third step (second async step, `close`) entirely because it was
entirely unnecessary by both implementations.

This PR generates deprecation log entries for each Role Descriptor,
used for building a Role, when the Role Descriptor grants more privileges
for an alias compared to an index that the alias points to. This is done in
preparation for the removal of the ability to define privileges over aliases.
There is one log entry for each "role descriptor name"-"alias name" pair.
On such a notice, the administrator is expected to modify the Role Descriptor
definition so that the name pattern for index names does not cover aliases.
Caveats:
* Role Descriptors that are not used in any authorization process,
either because they are not mapped to any user or the user they are mapped to
is not used by clients, are not be checked.
* Role Descriptors are merged when building the effective Role that is used in
the authorization process. Therefore some Role Descriptors can overlap others,
so even if one matches aliases in a deprecated way, and it is reported as such,
it is not at risk from the breaking behavior in the current role mapping configuration
and index-alias configuration. It is still reported because it is a best practice to
change its definition, or remove offending aliases.
As empty string has a certain meaning, the JDBC driver returns an empty
set instead for better client compatibility.

The invalid license enforced is exposed to the cluster state update
thread (via the license state listener) before the constructor has

means there is a concurrency bug lurking here. This commit addresses
this by avoiding publication of the invalid license enforcer before the
constructor has returned.

This opt-out query cache has an unsafe publication issue, where the
cache is exposed to another thread (namely the cluster state update
thread) before the constructor has finished execution. This exposes the

for license state changes until after the constructor has returned.

This adds a new security/qa test for TLS on a basic license.
It starts a 2 node cluster with a basic license, and TLS enabled
on both HTTP and Transport, and verifies the license type, x-pack
SSL usage and SSL certificates API.
It also upgrades the cluster to a trial license and performs that
same set of checks (to ensure that clusters with basic license
and TLS enabled can be upgraded to a higher feature license)

The security index had a few "object" types with
"dynamic": true
However, this automatically creates a mapping for each field that is
created within those objects. This means that types are dynamically
inferred and "locked in" for future updates.
Instead we want "dynamic": false which will allow us to store a range
of fields in these nested objects and retrieve them from the source,
without creating mapping types for those fields.

Many gradle projects specifically use the -try exclude flag, because
there are many cases where auto-closeable resource ignore is never
referenced in body of corresponding try statement. Suppressing this
warning specifically in each case that it happens using
`@SuppressWarnings("try")` would be very verbose.
This change removes `-try` from any gradle project and adds it to the
build plugin. Also this change removes exclude flags from gradle projects
that is already specified in build plugin (for example -deprecation).

When translating the original aggregation for the rollup indices,
the timezone of the date histogram is validated against the rollup
job but the value is not copied in the newly created date_histogram.
Prior to this PR, there is a bug in ILM which does not allow ILM to stop
if one or more indices have an index.lifecycle.name which refers to
a policy that does not exist - the operation_mode will be stuck as
STOPPING until either the policy is created or the nonexistent
policy is removed from those indices.
This change allows ILM to stop in this case and makes the logging more
clear as to why ILM is not stopping.
This change adds information about which UI path
(if any) created ML anomaly detector jobs to the

* ml_module_auditbeat_process_docker
* ml_module_auditbeat_process_hosts
* ml_module_nginx_access
* ml_module_sample
* multi_metric_wizard
* population_wizard
* single_metric_wizard
* unknown
The "unknown" count is for jobs that do not have a
created_by setting in their custom_settings.
