The existing joda compat methods isEquals isAfter and isBefore all took
in a ZonedDateTime, but since all of the scripting is now using the new
JodaCompatZonedDateTime, these are changed to take that in instead.
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Something along the same lines already happens in `BulkByScrollParallelizationHelper`, but the corresponding code went outdated as some new fields were added to `SearchRequest` which were not added to the bulk by scroll code.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.
* Adds deprecation logging to ScriptDocValues#getValues.
First commit addressing issue #22919.
`ScriptDocValues#getValues` was added for backwards compatibility but no
longer needed. Scripts using the syntax `doc['foo'].values` when
`doc['foo']` is a list should be using `doc['foo']` instead.
* Fixes two build errors in #34279
* Removes unused import in ScriptDocValuesDatesTest
* Removes used of `.values` in example in diversified-sampler-aggregation.asciidoc
* Removes use of .values from painless test.
Part of #34279
* Updates tests to use `doc[foo]` syntax rather than `doc[foo].values`.
* Removes use of `getValues()` and replaces use of `doc[foo].values` with `doc[foo]`.
* Indentation fix.
* Remove unnecessary list construction at previous `getValues()` callsite in ScriptDocValues.GeoPoints.
* Update migration doc and add link to `getValue` in ScriptDocValues javadoc.
* Fix compile
* Fix javadoc issue
* Removes ScriptDocValues#getValues usage from painless whitelist.
Includes the following:
* Reversion of doc-values changes in LUCENE-8374; we are interested in seeing if this
has an effect on benchmarks for node-stats and index-stats
* More improvements to docvalues updates
* Make sure to test conversion for both typed and typeless HLRC requests.
* Update a few more statements to deprecatedAndMaybeLog.
* Make sure Rest*SearchTemplateActionTests extend RestActionTestCase.
`PageCacheRecycler` is the class that creates and holds pages of arrays
for various uses. `BigArrays` is just one user of these pages. This
commit moves the constants that define the page sizes for the recycler
to be on the recycler class.
Currently our handshake requests do not include a version. This is
unfortunate as we cannot rely on the stream version since it is not the
sending node's version. Instead it is the minimum compatibility version.
The handshake request is currently empty and we do nothing with it. This
should allow us to add data to the request without breaking backwards
compatibility.
This commit adds the version to the handshake request. Additionally, it
allows "future data" to be added to the request. This allows nodes to craft
a version compatible response. And will properly handle additional data in
future handshake requests. The proper handling of "future data" is useful
as this is the only request where we do not know the other node's version.
Finally, it renames the TcpTransportHandshaker to
TransportHandshaker.
This adds casts for the def type to all standard boxed types. Prior to this certain
casts such as def [long/Long] -> Double would fail which does not follow the
goals of the Painless casting model to remove the need for explicit boxing. This
also creates symmetry with the casts for the newly created bridge methods
being called at run-time.
This commit modifies BigArrays to take a circuit breaker name and
the circuit breaking service. The default instance of BigArrays that
is passed around everywhere always uses the request breaker. At the
network level, we want to be using the inflight request breaker. So this
change will allow that.
Additionally, as this change moves away from a single instance of
BigArrays, the class is modified to not be a Releasable anymore.
Releasing big arrays was always dispatching to the PageCacheRecycler,
so this change makes the PageCacheRecycler the class that needs to be
managed and torn-down.
Finally, this commit closes#31435 be making the serialization of
transport messages use the inflight request breaker. With this change,
we no longer push the global BigArrays instnace to the network level.
This adds tests for each possible cast of def to a primitive type both implicit
and explicit. This also fixes a minor bug where we were only checking the type
of a def to be Number in some explicit casts. This does not work because it
allows possible unintended casts from BigInteger and BigDecimal to primitive
types since they both extend Number but are not included as part of the
Painless casting model.
The following updates were made:
- Add a new untyped endpoint `{index}/_explain/{id}`.
- Add deprecation warnings to Rest*Action, plus tests in Rest*ActionTests.
- For each REST yml test, make sure there is one version without types, and another legacy version that retains types (called *_with_types.yml).
- Deprecate relevant methods on the Java HLRC requests/ responses.
- Update documentation (for both the REST API and Java HLRC).
This commit converts the watcher execution context to use the joda
compat java time objects. It also again removes the joda methods from
the painless whitelist.
We use MethodHandles.asType to cast argument types into the appropriate parameter types for
method calls when the target of the call is a def type at runtime. Currently, certain implicit casts
using the def type are asymmetric. It is possible to cast Integer -> float as an argument to parameter, but not from int -> Float (boxed to primitive with upcasting is okay, but primitive to
boxed with upcasting is not).
This PR introduces a solution to the issue by generating bridge methods for all whitelisted methods
that have at least a single boxed type as an argument. The bridge method will conduct appropriate
casts and then call the original method. This adds a bit of overhead for correctness. It should not be
used often as Painless avoids boxed types as much as possible.
Note that a large portion of this change is adding methods to do the appropriate def to boxed type
casts and a few mechanical changes as well. The most important method for review is
generateBridgeMethod in PainlessLookupBuilder.

This commit hides ClusterStates that have a STATE_NOT_RECOVERED_BLOCK from
ClusterStateAppliers. This is needed, because some appliers, such as IngestService, rely on
the fact, that cluster states with STATE_NOT_RECOVERED_BLOCK won't contain anything useful.
Once the state is recovered it's fully available for the appliers. This commit also switches many of
the remaining tests that require state persistence/recovery from Zen1 to Zen2.
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`).

Today, we allow all nodes in an integration test to bootstrap. However this
seems to lead to test failures due to post-election instability. The change
avoids this instability by only bootstrapping a single node in the cluster.
This commit upgrades netty. This will close#35360. Netty started
throwing an IllegalArgumentException if a CompositeByteBuf is
created with < 2 components. Netty4Utils was updated to reflect this
change.
The `xContentType` was incorrectly serialized:
`xContentType.mediaTypeWithoutParameters()` was used to serialize, but
`xContentType.mediaType()` was used to de-serialize.
Also the serialization test class did not test `ContextSetup` well,
this was due to limitation in serialization test base class. Changed the
test class to manually test xcontent serialization, so that for both binary
and xcontent serialization tests, the `ContextSetup` is properly tested.
Closes#36050
The support for rest_total_hits_as_int has already been merged to 6x
in #35848 so this change adds this new option to master. The plan was
to add this new option as part of #35848 but we've decided to wait a few
days before merging this breaking change so this commit just handles
the new option as a noop exactly like 6x for now. This will allow
users to migrate to this parameter before #35848 is merged.

This is related to #34405 and a follow-up to #34753. It makes a number
of changes to our current keepalive pings.
The ping interval configuration is moved to the ConnectionProfile.
The server channel now responds to pings. This makes the keepalive
pings bidirectional.
On the client-side, the pings can now be optimized away. What this
means is that if the channel has received a message or sent a message
since the last pinging round, the ping is not sent for this round.

A number of tokenfilters can produce multiple tokens at the same position. This
is a problem when using token chains to parse synonym files, as the SynonymMap
requires that there are no stacked tokens in its input.
This commit ensures that when used to parse synonyms, these tokenfilters either produce
a single version of their input token, or that they throw an error when mappings are
generated. In indexes created in elasticsearch 6.x deprecation warnings are emitted in place
of the error.
* asciifolding and cjk_bigram produce only the folded or bigrammed token
* decompounders, synonyms and keyword_repeat are skipped
* n-grams, word-delimiter-filter, multiplexer, fingerprint and phonetic throw errors

This PR adds deprecation warnings to the relevant `Rest*Action` classes, plus tests in `Rest*ActionTests`. No updates to REST tests, the Java HLRC, or documentation were necessary, since they didn't make use of types.
This commit removes the dedicated `setSoLinger` method. This simplifies
the `TcpChannel` interface. This method has very little effect as the
SO_LINGER is not set prior to the channels being closed in the abstract
transport test case. We still will set SO_LINGER on the
`MockNioTransport`. However we can do this manually.
This pull request makes the `RestGetSourceAction` return a `ResourceNotFoundException` with a proper JSON response when source or document itself is missing (see issue #33384).

Zen2 is now feature-complete enough to run most ESIntegTestCase tests. The changes in this PR
are as follows:
- ClusterSettingsIT is adapted to not be Zen1 specific anymore (it was using Zen1 settings).
- Some of the integration tests require persistent storage of the cluster state, which is not fully
implemented yet (see #33958). These tests keep running with Zen1 for now but will be switched
over as soon as that is fully implemented.
- Some very few integration tests are not running yet with Zen2 for other reasons, depending on
some of the other open points in #32006.
This change fixes#35351. Users were no longer able to return types of numbers other than doubles for bucket aggregation scripts. This change reverts to the previous behavior of being able to return any type of number and having it converted to a double outside of the script.
This is related to #34483. It introduces a namespaced setting for
compression that allows users to configure compression on a per remote
cluster basis. The transport.tcp.compress remains as a fallback
setting. If transport.tcp.compress is set to true, then all requests
and responses are compressed. If it is set to false, only requests to
clusters based on the cluster.remote.cluster_name.transport.compress
setting are compressed. However, after this change regardless of any
local settings, responses will be compressed if the request that is
received was compressed.
Today when a percolator query contains a date range then the query
analyzer extracts that range, so that at search time the `percolate` query
can exclude percolator queries efficiently that are never going to match.
The problem is that if 'now' is used it is evaluated at index time.
So the idea is to rewrite date ranges with 'now' to a match all query,
so that the query analyzer can't extract it and the `percolate` query
is then able to evaluate 'now' at query time.
With the removal of SearchScript (#34730), an extraneous compile method
was left behind in PainlessScriptEngine. This change removes the method and
updates the tests that depend on it to use the main compile method which
gives better test coverage.
With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
This is related to #29023. Additionally at other points we have
discussed a preference for removing the need to unnecessarily block
threads for opening new node connections. This commit lays the groudwork
for this by opening connections asynchronously at the transport level.
We still block, however, this work will make it possible to eventually
remove all blocking on new connections out of the TransportService
and Transport.
Today if a wildcard, date-math expression or alias expands/resolves
to an index that is search-throttled we still search it. This is likely
not the desired behavior since it can unexpectedly slow down searches
significantly.
This change adds a new indices option that allows `search`, `count`
and `msearch` to ignore throttled indices by default. Users can
force expansion to throttled indices by using `ignore_throttled=true`
on the rest request to expand also to throttled indices.

This changes the current script.max_size_in_bytes to be dynamic so it can be
set through the cluster settings API. This setting is also applied to inline scripts
in the compile method of ScriptService to prevent excessively long inline
scripts from being compiled. The script length limit is removed from Painless as
this is no longer necessary with the protection in compile.
Currently we create a new netty event loop group for client connections
and all server profiles. Each new group creates new threads for io
processing. This means 2 * num of processors new threads for each group.
A single group should be able to handle all io processing (for the
transports). This also brings the netty module inline with what we do
for nio.
Additionally, this PR renames the worker threads to be the same for
netty and nio.
With this commit we differentiate between permanent circuit breaking
exceptions (which require intervention from an operator and should not
be automatically retried) and transient ones (which may heal themselves
eventually and should be retried). Furthermore, the parent circuit
breaker will categorize a circuit breaking exception as either transient
or permanent based on the categorization of memory usage of its child
circuit breakers.

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.
Relates to #34488
Drops the `Settings` member from `AbstractComponent`, moving it from the
base class on to the classes that use it. For the most part this is a
mechanical change that doesn't drop `Settings` accesses. The one
exception to this is naming threads where it switches from an invocation
that passes `Settings` and extracts the node name to one that explicitly
passes the node name.
This change doesn't drop the `Settings` argument from
`AbstractComponent`'s ctor because this change is big enough as is.
We'll do that in a follow up change.
In order to remove Streamable from the codebase, Response objects need
to be read using the Writeable.Reader interface which this change
enables. This change enables the use of Writeable.Reader by adding the
`Action#getResponseReader` method. The default implementation simply
uses the existing `newResponse` method and the readFrom method. As
responses are migrated to the Writeable.Reader interface, Action
classes can be updated to throw an UnsupportedOperationException when
`newResponse` is called and override the `getResponseReader` method.

This commit adds a new ParentJoinAggregator that implements a join using global ordinals
in a way that can be reused by the `children` and the upcoming `parent` aggregation.
This new aggregator is a refactor of the existing ParentToChildrenAggregator with two main changes:
* It uses a dense bit array instead of a long array when the aggregation does not have any parent.
* It uses a single aggregator per bucket if it is nested under another aggregation.
For the latter case we use a `MultiBucketAggregatorWrapper` in the factory in order to ensure that each
instance of the aggregator handles a single bucket. This is more inlined with the strategy we use for other
aggregations like `terms` aggregation for instance since the number of buckets to handle should be low (thanks to the breadth_first strategy).
This change is also required for #34210 which adds the `parent` aggregation in the parent-join module.

After discussing on the team's FixItFriday, we concluded that
static final instance variables that are mutable should be lowercased.
Historically, DeprecationLogger was uppercased more frequently than lowercased.
This is related to #30876. The AbstractSimpleTransportTestCase initiates
many tcp connections. There are normally over 1,000 connections in
TIME_WAIT at the end of the test. This is because every test opens at
least two different transports that connect to each other with 13
channel connection profiles. This commit modifies the default
connection profile used by this test to 6. One connection for each
type, except for REG which gets 2 connections.
The contains syntax was added in #30874 but the skips were not properly
put in place.
The java runner has the feature so the tests will run as part of the
build, but language clients will be able to support it at their own
pace.
This change adds instance bindings to Painless. This binding allows a whitelisted
method to be called on an instance instantiated prior to script compilation.
Whitelisting must be done in code as there is no practical way to instantiate a
useful instance from a text file (see the tests for an example). Since an
instance can be shared by multiple scripts, each method called must be
thread-safe.
We throw parsing exception when an unknown array is found, but we don't when an unknown top-level field is found. This commit makes sure that unsupported top-level fields are not ignored in a do section.

This commit introduces two corrections to the way simulate?verbose
handles conditionals on processors.
1) Prior to this change when executing simulate?verbose for
processors with conditionals that evaluate to false, that processor
would still be displayed in the result set. What was displayed was
correct, such that no changes to the document occurred. However, if the
conditional evaluates to false, the processor should not even be
displayed.
2) Prior to this change when executing simulate?verbose for
pipeline processors with conditionals, the individual steps would no
longer be displayed. Commit e37e5df addressed the issue, but
failed account for a conditional on the pipeline processor. Since
a pipeline processor can introduce cycles and is effectively a
single processor that encapsulates multiple other processors that
are potentially guarded by a single conditional, special handling is
needed to for pipeline and conditional pipeline processors.
