Changes:
* Swaps the `dev` admonitions for `experimental` admonitions
* Removes `ifdef` statements preventing the docs from appearing in
released branches
This PR ensure that same roles are cached only once even when they are from different API keys.
API key role descriptors and limited role descriptors are now saved in Authentication#metadata
as raw bytes instead of deserialised Map<String, Object>.
Hashes of these bytes are used as keys for API key roles. Only when the required role is not found
in the cache, they will be deserialised to build the RoleDescriptors. The deserialisation is directly
from raw bytes to RoleDescriptors without going through the current detour of
"bytes -> Map -> bytes -> RoleDescriptors".
The code path for closed indices is dead code here ever since #39644
because `shards(currentState, indexIds, ...)` does not set
`MISSING` on a closed index's shard that is assigned any longer. Before that change it would always set `MISSING` for a closed index's shard even it was assigned.
=> simplified the code accordingly.
In #52680 we introduced a new health check mechanism. This commit fixes
up some related test failures on Windows caused by erroneously assuming
that all paths begin with `/`.
Closes#59380
With #55773 the snapshot INIT state step has become obsolete. We can set up the snapshot directly in one single step to simplify the state machine.
This is a big help for building concurrent snapshots because it allows us to establish a deterministic order of operations between snapshot create and delete operations since all of their entries now contain a repository generation. With this change simple queuing up of snapshot operations can and will be added in a follow-up.
We have a number of parameters which are universally parsed by almost all
mappers, whether or not they make sense. Migrating the binary and boolean
mappers to the new style of declaring their parameters explicitly has meant
that these universal parameters stopped being accepted, which would break
existing mappings.
This commit adds some extra logic to ParametrizedFieldMapper that checks
for the existence of these universal parameters, and issues a warning on
7x indexes if it finds them. Indexes created in 8.0 and beyond will throw an
error.
Fixes#59359
This refactoring has three motivations:
1. Separate all master node steps during snapshot operations from all data node steps in code.
2. Set up next steps in concurrent repository operations and general improvements by centralizing tracking of each shard's state in the repository in `SnapshotsService` so that operations for each shard can be linearized efficiently (i.e. without having to inspect the full snapshot state for all shards on every cluster state update, allowing us to track more in memory and only fall back to inspecting the full CS on master failover like we do in the snapshot shards service).
* This PR already contains some best effort examples of this, but obviously this could be way improved upon still (just did not want to do it in this PR for complexity reasons)
3. Make the `SnapshotsService` less expensive on the CS thread for large snapshots

- Required minor rework on common repository setup to allow distribution projects
to resolve thirdparty artifacts
- Use Default configurations when resolving tools for distribution packaging

With the removal of mapping types and the immutability of FieldTypeLookup in #58162, we no longer
have any cause to compare MappedFieldType instances. This means that we can remove all equals
and hashCode implementations, and in addition we no longer need the clone implementations which
were required for equals/hashcode testing. This greatly simplifies implementing new MappedFieldTypes,
which will be particularly useful for the runtime fields project.
This adds a setting to data frame analytics jobs called
`max_number_threads`. The setting expects a positive integer.
When used the user specifies the max number of threads that may
be used by the analysis. Note that the actual number of threads
used is limited by the number of processors on the node where
the job is assigned. Also, the process may use a couple more threads
for operational functionality that is not the analysis itself.
This setting may also be updated for a stopped job.
More threads may reduce the time it takes to complete the job at the cost
of using more CPU.

This modifies the `variable_width_histogram`'s distant bucket handling
to:
1. Properly handle integer overflows
2. Recalculate the average distance when new buckets are added on the
ends. This should slow down the rate at which we build extra buckets
as we build more of them.

Sequences now support until conditional, which prevents a match from
occurring if the until matches a document while doing look-ups.
Thus a sequence must complete before the until condition matches - if
any document within the sequence occurs at, or after, the until hit, the
sequence is discarded.

Since we are able to load the inference model
and perform inference in java, we no longer need
to rely on the analytics process to be performing
test inference on the docs that were not used for
training. The benefit is that we do not need to
send test docs and fit them in memory of the c++
process.

In #52680 we introduced a new health check mechanism. This commit fixes
up some sporadic related test failures, and improves the behaviour of
the `FollowersChecker` slightly in the case that no retries are
configured.

Today `NodeEnvironment#findAllShardIds` enumerates the index directories
in each data path in order to find one with a specific name. Since we
already know the name of the folder we seek we can construct the path
directly and avoid this directory listing. This commit does that.
The FieldMapper infrastructure currently has a bunch of shared parameters, many of which
are only applicable to a subset of the 41 mapper implementations we ship with. Merging,
parsing and serialization of these parameters are spread around the class hierarchy, with
much repetitive boilerplate code required. It would be much easier to reason about these
things if we could declare the parameter set of each FieldMapper directly in the implementing
class, and share the parsing, merging and serialization logic instead.
This commit is a first effort at introducing a declarative parameter style. It adds a new FieldMapper
subclass, ParametrizedFieldMapper, and refactors two mappers, Boolean and Binary, to use it.
Parameters are declared on Builder classes, with the declaration including the parameter name,
whether or not it is updateable, a default value, how to parse it from mappings, and how to
extract it from another mapper at merge time. Builders have a getParameters method, which
returns a list of the declared parameters; this is then used for parsing, merging and serialization.
Merging is achieved by constructing a new Builder from the existing Mapper, and merging in
values from the merging Mapper; conflicts are all caught at this point, and if none exist then a new,
merged, Mapper can be built from the Builder. This allows all values on the Mapper to be final.
Other mappers can be gradually migrated to this new style, and once they have all been refactored
we can merge ParametrizedFieldMapper and FieldMapper entirely.
