Implement a more trivial case of the CASE expression which is
expressed as a traditional function with 2 or 3 arguments. e.g.:
IIF(a = 1, 'one', 'many')
IIF(a > 0, 'positive')

Implement the ANSI SQL CASE expression which provides the if/else
functionality common to most programming languages.
The CASE expression can have multiple WHEN branches and becomes a
powerful tool for SQL queries as it can be used in SELECT, WHERE,
GROUP BY, HAVING and ORDER BY clauses.

The `DistinguishedNamePredicate`, used for matching users to role mapping
expressions, should handle users with null DNs. But it fails to do so (and this is
a NPE bug), if the role mapping expression contains a lucene regexp or a wildcard.
The fix simplifies `DistinguishedNamePredicate` to not handle null DNs at all, and
instead use the `ExpressionModel#NULL_PREDICATE` for the DN field, just like
any other missing user field.
The X-Pack plugin implements ScriptEngine yet it does not actually
implement any of the methods on the interface, effectively making this a
no-op. This commit removes this interface from the X-Pack plugin.
It looks like these permissions were copy/pasted from another plugin yet
almost none of these permissions are needed for the CCR plugin. This
commit removes all these unneeded permissions from the CCR plugin.
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
those new instances and since the resolveType() wasn't called again
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
-----------------
foo

This commit extracts the template management from Watcher into an
abstract class, so that templates and lifecycle policies can be managed
in the same way across multiple plugins. This will be useful for SLM, as
well as potentially ILM and any other plugins which need to manage index
templates.
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
implementations.

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
that and restricts the limit only to sorting.

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.
This is related to #36652. We intend to deprecate a number of transport
settings in 7.x and remove them in 8.0. This commit removes the string
usages of these settings.
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.
Relates to #16347
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.
Closes#40194
Backport of (#41087)
* 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.
