For cross cluster search alternate execution mode (see #32125), we will need to take a search request that spans across multiple clusters (based on index prefixes e.g. cluster1:index, cluster2:index etc.) and split it into multiple search requests to be sent to each cluster. A copy constructor added to `SearchRequest` would make that easy and well maintainable in the future.
Something along the same lines already happens in `BulkByScrollParallelizationHelper`, but the corresponding code went outdated as some new fields were added to `SearchRequest` which were not added to the bulk by scroll code. A copy constructor helps making the task of copying a search request maintainable over time.
This commit changes the format of the `hits.total` in the search response to be an object with
a `value` and a `relation`. The `value` indicates the number of hits that match the query and the
`relation` indicates whether the number is accurate (in which case the relation is equals to `eq`)
or a lower bound of the total (in which case it is equals to `gte`).
This change also adds a parameter called `rest_total_hits_as_int` that can be used in the
search APIs to opt out from this change (retrieve the total hits as a number in the rest response).
Note that currently all search responses are accurate (`track_total_hits: true`) or they don't contain
`hits.total` (`track_total_hits: true`). We'll add a way to get a lower bound of the total hits in a
follow up (to allow numbers to be passed to `track_total_hits`).

This commit replaces usages of Streamable with Writeable for the
BaseTasksResponse / TransportTasksAction classes and subclasses of
these classes.
Note that where possible response fields were made final.

Stop passing `Settings` to `AbstractComponent`'s ctor. This allows us to
stop passing around `Settings` in a *ton* of places. While this change
touches many files, it touches them all in fairly small, mechanical
ways, doing a few things per file:
1. Drop the `super(settings);` line on everything that extends
`AbstractComponent`.
2. Drop the `settings` argument to the ctor if it is no longer used.
3. If the file doesn't use `logger` then drop `extends
AbstractComponent` from it.
4. Clean up all compilation failure caused by the `settings` removal
and drop any now unused `settings` isntances and method arguments.
I've intentionally *not* removed the `settings` argument from a few
files:
1. TransportAction
2. AbstractLifecycleComponent
3. BaseRestHandler
These files don't *need* `settings` either, but this change is large
enough as is.

This change cleans up "unused variable" warnings. There are several cases were we
most likely want to suppress the warnings (especially in the client documentation test
where the snippets contain many unused variables). In a lot of cases the unused
variables can just be deleted though.
This commit removes the sysprop controlling whether ctx is in params for
update scripts and replaces it with use of the new ParameterMap, which
outputs a deprecation warning whenever params.ctx is used.
Drops `Settings` from some of the methods to lookup loggers and
deprecates another logger lookup that takes `Settings` because
`Settings` is no longer required to build a logger.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. In a
long series of PRs I've changed all of the old style requests that I
could find with `grep`. In this PR I change all requests that I could
find by *removing* the deprecated methods. Since this is a non-trivial
change I do not include actually removing the deprecated requests. I'll
do that in a follow up. But this should be the last set of usage
removals before the actual deprecated method removal. Yay!
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. This
changes all calls in the `modules/reindex` project to use the new
versions.
TransportAction currently contains 2 doExecute methods, one which takes
a the task, and one that does not. The latter is what some subclasses
implement, while the first one just calls the latter, dropping the given
task. This commit combines these methods, in favor of just always
assuming a task is present.
Most transport actions don't need the node ThreadPool. This commit
removes the ThreadPool as a super constructor parameter for
TransportAction. The actions that do need the thread pool then have a
member added to keep it from their own constructor.
Most transport actions don't need to resolve index names. This commit
removes the index name resolver as a super constructor parameter for
TransportAction. The actions that do need the resolver then have a
member added to keep the resolver from their own constructor.
Since #30966, Action no longer has anything but a call to the
GenericAction super constructor. This commit renames GenericAction
into Action, thus eliminating the Action class. Additionally, this
commit removes the Request generic parameter of the class, since
it was unused.
This commit upgrades us to Netty 4.1.25. This upgrade is more
challenging than past upgrades, all because of a new object cleaner
thread that they have added. This thread requires an additional security
permission (set context class loader, needed to avoid leaks in certain
scenarios). Additionally, there is not a clean way to shutdown this
thread which means that the thread can fail thread leak control during
tests. As such, we have to filter this thread from thread leak control.
The following analyzers were moved from server module to analysis-common module:
`snowball`, `arabic`, `armenian`, `basque`, `bengali`, `brazilian`, `bulgarian`,
`catalan`, `chinese`, `cjk`, `czech`, `danish`, `dutch`, `english`, `finnish`,
`french`, `galician` and `german`.

This commit removes the RequestBuilder generic type from Action. It was
needed to be used by the newRequest method, which in turn was used by
client.prepareExecute. Both of these methods are now removed, along with
the existing users of prepareExecute constructing the appropriate
builder directly.
Currently failures to compile a script usually lead to a ScriptException, which
inherits the 500 INTERNAL_SERVER_ERROR from ElasticsearchException if it does
not contain another root cause. Instead, this should be a 400 Bad Request error.
This PR changes this more generally for script compilation errors by changing
ScriptException to return 400 (bad request) as status code.
Closes#12315
This commit changes the default out-of-the-box configuration for the
number of shards from five to one. We think this will help address a
common problem of oversharding. For users with time-based indices that
need a different default, this can be managed with index templates. For
users with non-time-based indices that find they need to re-shard with
the split API in place they no longer need to resort only to
reindexing.
Since this has the impact of changing the default number of shards used
in REST tests, we want to ensure that we still have coverage for issues
that could arise from multiple shards. As such, we randomize (rarely)
the default number of shards in REST tests to two. This is managed via a
global index template. However, some tests check the templates that are
in the cluster state during the test. Since this template is randomly
there, we need a way for tests to skip adding the template used to set
the number of shards to two. For this we add the default_shards feature
skip. To avoid having to write our docs in a complicated way because
sometimes they might be behind one shard, and sometimes they might be
behind two shards we apply the default_shards feature skip to all docs
tests. That is, these tests will always run with the default number of
shards (one).
This folds the `:qa:smoke-test-reindex-with-all-modules` project into
`:modules:reindex` by declaring the reindex's integration testing
cluster requires the `parent-join` and `lang-painless` plugins and then
moving all of the integration tests that depended on parent-join and
painless into reindex.
It saves us one cluster start up during the build at the cost of a
little of the reindex module's "purity". Since the reindex module *does*
have unit tests that test scripting without painless I'm fairly ok with
that.
Previously `BulkProcessor` retry logic was based on the exception type of the failed response (`EsRejectedExecutionException`). This commit changes it to be based on the returned status code. This allows us to reproduce the same retry behaviour when the `BulkProcessor` is used from the high-level REST client, which was previously not the case as we cannot rebuild the same exception type when parsing back the response. This change has no effect on the transport client.
