This change allows the submit async search task to cancel children
and removes the manual indirection that cancels the search task when the submit
task is cancelled. This is now handled by the task cancellation, which can cancel
grand-children since #54757.
When assigning ports for internal cluster tests, we use the gradle
worker id as an adjustment on the base port of 10300. In order to not go
outside the max port range, we modulo the worker id by 223. Since gradle
worker ids start at 1, we expect to never actually get the base port of
10300. However, as the gradle daemon lasts for longer, the module can
result in a value of 0, which cases the test to fail. This commit
adjusts the modulo to ensure the value is never 0.

This commit creates a shared withCustomConfig method that may be used by
any packaging test. The method will copy the config directory and
override the conf path appropriately depending on the distribution type.
This commits allows data streams to be a valid source for analytics and transforms.
Data streams are fairly transparent and our `_search` and `_reindex` actions work without error.
For `_transforms` the check-pointing works as desired as well. Data streams are effectively treated as an `alias` and the backing index values are stored within checkpointing information.
GET inference stats now reads from the .ml-stats index.
Our tests should wait for yellow state before attempting to query the index for stat information.
Unlike `classification`, which is using a cross validation splitter
that produces training sets whose size is predictable and equal to
`training_percent * class_cardinality`, for regression we have been
using a random splitter that takes an independent decision for each
document. This means we cannot predict the exact size of the training
set. This poses a problem as we move towards performing test inference
on the java side as we need to be able to provide an accurate upper
bound of the training set size to the c++ process.
This commit replaces the random splitter we use for regression with
the same streaming-reservoir approach we do for `classification`.
Backport of #58331
Improve the usability of the MS-SQL server/ODBC escaped
date/time/timestamp literals, by allowing timezone/offset ids
in the parsed string, e.g.:
```
{ts '2000-01-01T11:11:11Z'}
```

Very rarely this test can fail if we draw a random TimeZone id that we cannot
parse with the legacy joda DateMathParser and get an IllegalArgumentException.
In addition to a "SystemV/*" time zone we also need an index "versionCreated"
before V_7_0_0 and no "format" setting in the query builder. Given how unlikely
this combination is, we should simply dissallow those time zone ids when
generating the random query builder for RangeQueryBuilderTests.
Closes#58431
There was a discrepancy in the implementation of flush
acknowledgements: most of the class was designed on the
basis that the "last finalized bucket time" could be null
but the wire serialization assumed that it was never
null. This works because, the C++ sends zero "last
finalized bucket time" when it is not known or not
relevant. But then the Java code will print that to
XContent as it is assuming null represents not known or
not relevant.
This change corrects the discrepancies. Internally within
the class null represents not known or not relevant, but
this is translated from/to 0 for communications from the
C++ and old nodes that have the bug.
Additionally I switched from Date to Instant for this
class and made the member variables final to modernise it
a bit.
Backport of #58413
Now that MappedFieldType no longer extends lucene's FieldType, we need to have a
way of getting the index information about a field necessary for building text queries,
building term vectors, highlighting, etc. This commit introduces a new TextSearchInfo
abstraction that holds this information, and a getTextSearchInfo() method to
MappedFieldType to make it available. Field types that do not support text search can
just return null here.
This allows us to remove the MapperService.getLuceneFieldType() shim method.
This merges the aggregator for `significant_text` into
`significant_terms`, applying the optimization built in #55873 to save
memory when the aggregation is not on top. The `significant_text`
aggregation is pretty memory intensive all on its own and this doesn't
particularly help with that, but it'll help with the memory usage of any
sub-aggregations.
Just like #56094 but for the request side.
Removes a lot of redundant `ShardId` instances from bulk shard requests as well as stops serializing index names when they're not needed because they're not different from what is in the shard id.
Even ignoring the index name serialization savings here, this change saves one `ShardId` instance per bulk shard request at least. This means it saves approximately:
* 8 bytes for the `ShardId` object (itself + one field)
* + another 4 bytes for the `int` in the `ShardId`
* 16 bytes (two fields + the instance itself + the padding) for the `Index` object
* + 30 bytes for the `Index` uuid string
* + all the bytes in the index name string
=> 60+ bytes per bulk request item saved on heap and over the wire
Today the `PublicationContext` interface has a single anonymous
implementation, and `PublicationTransportHandler` has various methods
that take the variables that this anonymous class captures. This commit
refactors this into a proper class with proper fields and moves the
relevant methods onto this class.
Backport of #58405 to 7.x.
FieldTypeLookup maps field names to their MappedFieldTypes. In the past, due to
the presence of multiple mapping types within a single index, this had to be updated
in-place because a mapping update might only affect one type. However, now that
we only have a single type per index, we can completely rebuild the FieldTypeLookup
on each update, removing lots of concurrency worries.
Adds a new value to the "event" enum of ML annotations, namely
"categorization_status_change".
This will allow users to see when categorization was found to
be performing poorly. Once per-partition categorization is
available, it will allow users to see when categorization is
performing poorly for a specific partition.
It does not make sense to reuse the "model_change" event that
annotations already have, because categorizer state is separate
to model state ("model" state is really anomaly detector state),
and is not reverted by the revert model snapshot API.
Therefore annotations related to categorization need to be
treated differently to annotations related to anomaly detection.

* use mapping source direcly instead of using mapper service to extract the relevant mapping details
* moved assertion to TimestampField class and added helper method for tests
* Improved logic that inserts timestamp field mapping into an mapping.
If the timestamp field path consisted out of object fields and
if the final mapping did not contain the parent field then an error
occurred, because the prior logic assumed that the object field existed.
When doing aliasing with the same name over non existing fields, the analyzer gets stuck in a loop trying to resolve the alias over and over leading to SO. This PR breaks the cycle by checking the relationship between the alias and the child it tries to replace as an alias should never replace its child.

* Add support for snapshot and restore to data streams (#57675)
This change adds support for including data streams in snapshots.
Names are provided in indices field (the same way as in other APIs), wildcards are supported.
If rename pattern is specified it renames both data streams and backing indices.
It also adds test to make sure SLM works correctly.

When a local model is constructed, the cache hit miss count is incremented.
When a user calls _stats, we will include the sum cache hit miss count across ALL nodes. This statistic is important to in comparing against the inference_count. If the cache hit miss count is near the inference_count it indicates that the cache is overburdened, or inappropriately configured.
This adds validation to make sure alias operations (add, remove, remove index)
don't target data streams or the backing indices.

The packaging tests currently have a couple different ways of deciding
where temp files should be placed, and then sometimes used fixed file
or directory names within that dir. This commit conslidates some of that
temp dir handling by making it more compatible with the handling that
exists within the bats tests, where /tmp is not always appropriate due
to how systemd interacts with it. This commit also adds a utility
methhod for creating temp dirs, so as to ensure the new directory is
created as if a umask of 022 were used, which is not the case when using
Files.createTempDirectory without a set of permissions (it assumes 077).
This commit fixes an AOOBE in the handling of fatal
failures in _async_search. If the underlying cause is not found,
this change uses the root failure.
Closes#58311
Today when creating a follower index via the put follow API, or via an
auto-follow pattern, it is not possible to specify settings overrides
for the follower index. Instead, we copy all of the leader index
settings to the follower. Yet, there are cases where a user would want
some different settings on the follower index such as the number of
replicas, or allocation settings. This commit addresses this by allowing
the user to specify settings overrides when creating follower index via
manual put follower calls, or via auto-follow patterns. Note that not
all settings can be overrode (e.g., index.number_of_shards) so we also
have detection that prevents attempting to override settings that must
be equal between the leader and follow index. Note that we do not even
allow specifying such settings in the overrides, even if they are
specified to be equal between the leader and the follower
index. Instead, the must be implicitly copied from the leader index, not
explicitly set by the user.
Fixes a bug in TextFieldMapper serialization when index is false, and adds a
base-class test to ensure that all field mappers are tested against all variations
with defaults both included and excluded.
Fixes#58188
TIME_PARSE works correctly if both date and time parts are specified,
and a TIME object (that contains only time is returned).
