* Name Snapshot Data Blobs by UUID
* There is no functional reason why we need incremental naming for these files but
* As explained in #38941 it is a possible source of corrupting the repository
* It wastes API calls for the list operation
* Is just needless complication
* Since we store the exact names of the data blobs in all the metadata anyway, we can make this change without any BwC considerations
* Even on the worst case scenario of a downgrade the functionality would continue working since the incremental names wouldn't conflict with the uuids and the number parsing for finding the next incremental name suppresses the exception when encountring a non-numeric value after the double underscore prefix
In order to support empty action metadata in the first msearch item,
we need to remove support for prepending msearch request body with an
empty line, which prevents us from parsing the empty line as action
metadata for the first search item.
Relates to #41011
The test is testing the java time API and fails in case it hits daylight saving time changes.
Java time has the right implementation and we don't need to test this.

The Has Privileges API allows to tap into the authorization process, to validate
privileges without actually running the operations to be authorized. This commit
fixes a bug, in which the Has Privilege API returned spurious results when checking
for index privileges over restricted indices (currently .security, .security-6,
.security-7). The actual authorization process is not affected by the bug.
hamcrest has some improvements in newer versions, like FileMatchers
that make assertions regarding file exists cleaner. This commit upgrades
to the latest version of hamcrest so we can start using new and improved
matchers.
* Due to #40866 one of the two parallel bulk requests can randomly be
rejected outright when the write queue is full already, we can catch
this situation and ignore it since we can still have the rejection for
the dynamic mapping udate for the other reuqest and it's somewhat rare
to run into this anyway
* Closes#41363
We link to these migraiton docs but we don't specify the id. This
isn't great practice in general and is preventing us from migrating to
Asciidoctor because it generates ids in a slightly different way.
Adds some validation to prevent duplicate source names from being
used in the composite agg.
Also refactored to use a ConstructingObjectParser and removed the
private ctor and setter for sources, making it mandatory.
* The problem here is that if we run into a corrupted index-N file, instead of generating a new index-(N+1) file, we instead set the newest index generation to -1 and thus tried to create `index-0`
* If `index-0` is corrupt, this prevents us from ever creating a new snapshot using the broken shard, because we are unable to create `index-0` since it already exists
* Fixed by still using the index generation for naming the next index file, even if it was a broken index file
* Added test that makes sure restoring as well as snapshotting on top of the broken shard index file work as expected
* closes#41304
* The test fails for the retry backoff enabled case because the retry handler in the bulk processor hasn't been adjusted to account for #40866 which now might lead to an outright rejection of the request instead of its items individually
* Fixed by adding retry functionality to the top level request as well
* Also fixed the duplicate test for the HLRC that wasn't handling the non-backoff case yet the same way the non-client IT did
* closes#41324
This adds a gradle task called generateContextDoc in the Painless module. The
task will start a cluster, issue commands against the context rest api for
Painless, and generate documentation for each API per context. Each context
has a first page of classes sorted by package first and class name second,
along with a page per package with each classes' constructors, methods, and
fields. A link is generated for each constructor, method, and field to a JavaDoc
page when possible.
Drops some inline callouts that snuck into 7.x. We're doings this in
preparation for switching the elasticsearch reference to asciidoctor
which doesn't support them.
* fix#35262 define deprecations of API's as a whole and urls
* document hot threads deprecated paths
* deprecate scroll_id as part of the URL, documented only as part of the body which is a safer behaviour as well
* use version numbers up to patch version
* rest spec parser picks up deprecated paths as paths too

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')

It can be the case that while we are setting up expectations that also a
log message is appended. For example, if we are setting up these
expectations after a cluster has formed and messages start being sent
around the cluster. In this case, we would hit a concurrent modification
exception while we are mutating the expectations, and also while the
expectations are being iterated over as a message is appended. This
commit avoids this by using a copy-on-write array list which is safe for
concurrent modification and iteration. Note that another possible
approach here is to use synchronized, but that seems unnecessary since
we don't appear to rely on messages that are sent while we are setting
up expectations. Rather, we are setting up some expectations and some
situation that we think will cause those expectations to be met. Using
copy-on-write array list here is nice since we avoid bottlenecking these
tests on synchronizing these methods.
The example to delete a remote cluster is missing the `skip_unavailable` setting which results in an error:
```
"type": "illegal_argument_exception",
"reason": "missing required setting [cluster.remote.tiny-test.seeds] for setting [cluster.remote.tiny-test.skip_unavailable]"
```
The pid dir for both systemd and init.d is already managed by those
respective systems (tmpfiles.d and the init script, respectively). Since
the /var/run dir is often mounted as tmpfs, it does not make sense to
have the elasticsearch pid dir added by the package installation. This
commit removes that empty dir from deb and rpm.
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.
Today's `docker-compose` docs are missing the `discovery.seed_nodes` config on
one of the nodes. With today's configuration the cluster can still form the
first time it is started, because `cluster.initial_master_nodes` requires both
nodes to bootstrap the cluster which ensures that each discover the other.
However if `es02` is elected master it will remove `es01` from the voting
configuration and then when restarted it will form a cluster on its own without
needing to do any discovery. Meanwhile `es01` doesn't know how to find `es02`
after a restart so will be unable to join this cluster.
This commit fixes this by adding the missing configuration.
To reduce configuration time, we fork some threads to compute the Java
version for the various configured Javas. However, as the number of
JAVA${N}_HOME variable increases, the current implementation creates as
many threads as there are such variables, which could be more than the
number of physical cores on the machine. It is not likely that we would
see benefits to trying to execute all of these once beyond the number of
physical cores (maybe simultaneous multi-threading helps though, who
knows. Therefore, this commit limits the parallelization here to the
number number of physical cores.
This commit adds a filter to the files include from modules to only
include platform specific files relevant to the distribution being
built. For example, the deb files on linux would now only include linux
ML binaries, and not windows or macos files.
If no Java versions are set then when we size the executor thread pool
we end up with zero threads, which is illegal. This commit avoids that
problem by only starting the executor when needed.
