* Update the REST API specification
This patch updates the REST API spefication in JSON files to better encode deprecated entities,
to improve specification of URL paths, and to open up the schema for future extensions.
Notably, it changes the `paths` from a list of strings to a list of objects, where each
particular object encodes all the information for this particular path: the `parts` and the `methods`.
Among the benefits of this approach is eg. encoding the difference between using the `PUT` and `POST`
methods in the Index API, to either use a specific document ID, or let Elasticsearch generate one.
Also `documentation` becomes an object that supports an `url` and also a `description` which is a
new field.
* Adapt YAML runner to new REST API specification format
The logic for choosing the path to use when running tests has been
simplified, as a consequence of the path parts being listed under each
path in the spec. The special case for create and index has been removed.
Also the parsing code has been hardened so that errors are thrown earlier
when the structure of the spec differs from what expected, and their
error messages should be more helpful.
* Painless generates a ton of duplicate strings and empty `Hashmap` instances wrapped as unmodifiable
* This change brings down the static footprint of Painless on an idle node by 20MB (after running the PMC benchmark against said node)
* Since we were looking into ways of optimizing for smaller node sizes I think this is a worthwhile optimization
This change removes the Reserved class used to track variables usages
within the ANTLR grammar. That task is now performed by an existing pass
"extractVariables" in the Painless AST. The Painless AST no longer has any
dependencies on the ANTLR AST for state outside of the tree being built.
This will simplify future refactoring and opens the possibility of alternate
grammars.
This change adds a compiler pass to give each node the chance to store
settings necessary for analysis and writing. This removes the need to pass
this in a somewhat convoluted way through an additional class called
Reserved, and also removes the need to have the Walker set values for
settings on reserved. This is next step in decoupling the Painless grammar
from the Painless AST.
This is the first step in decoupling the Painless AST from the grammar. The
Painless AST should be able to generate classes independently of how the
AST is generated from a grammar. (If I were to build a Painless AST by hand
in code this should be all that's necessary.) This change removes Lambda
name generation from the ANTLR grammar tree walker. It also removes
unnecessary node generation of new array function references from the
tree walker as well.
This adjusts the `buckets_path` parser so that pipeline aggs can
select specific buckets (via their bucket keys) instead of fetching
the entire set of buckets. This is useful for bucket_script in
particular, which might want specific buckets for calculations.
It's possible to workaround this with `filter` aggs, but the workaround
is hacky and probably less performant.
- Adjusts documentation
- Adds a barebones AggregatorTestCase for bucket_script
- Tweaks AggTestCase to use getMockScriptService() for reductions and
pipelines. Previously pipelines could just pass in a script service
for testing, but this didnt work for regular aggs. The new
getMockScriptService() method fixes that issue, but needs to be used
for pipelines too. This had a knock-on effect of touching MovFn,
AvgBucket and ScriptedMetric
This whitelists randomUUID with the understanding that it's possible for
/dev/random to cause blocking on *nix systems. Users that need
randomUUID should switch their random generator source to /dev/urandom
if this is a concern for them.
This is a temporary fix during the Joda to Java datetime transition. This will
implicitly cast a JodaCompatibleZonedDateTime to a ZonedDateTime for
both def and static types. This is necessary to insulate users from needing
to know about JodaCompatibleZonedDateTime explicitly.
While joda no longer exists in the apis for 7.x, the compatibility layer
still exists with helper methods mimicking the behavior of joda for
ZonedDateTime objects returned for date fields in scripts. This layer
was originally intended to be removed in 7.0, but is now likely to exist
for the lifetime of 7.x.
This commit adds missing methods from ChronoZonedDateTime to the compat
class. These methods were not part of joda, but are needed to act like a
real ZonedDateTime.

Well, we have a test here that intentionally causes an OutOfMemoryError,
to ensure that Painless handles it (I still strongly disagree with doing
this). This causes two things to happen: an OutOfMemoryError to be
dumped to the console, and the heap to be dumped to disk. This makes it
look like we had an OutOfMemoryError while running tests, and the tests
did not fail properly. This commit changes the tests configuration so
that we suppress the heap dump, which also causes the OutOfMemoryError
to no longer be dumped to the console.
this commit removes usage of the deprecated
constructor with a single argument and no Writeable.Reader.
The purpose of this is to reduce the boilerplate necessary for
properly implementing a new action, as well as reducing the
chances of using the incorrect super constructor while classes
are being migrated to Writeable
relates #34389.
The base classes for transport requests and responses currently
implement Streamable and Writeable. The writeTo method on these base
classes is implemented with an empty implementation. Not only does this
complicate subclasses to think they need to call super.writeTo, but it
also can lead to not implementing writeTo when it should have been
implemented, or extendiong one of these classes when not necessary,
since there is nothing to actually implement.
This commit removes the empty writeTo from these base classes, and fixes
subclasses to not call super and in some cases implement an empty
writeTo themselves.
relates #34389
Action is a class that encapsulates meta information about an action
that allows it to be called remotely, specifically the action name and
response type. With recent refactoring, the action class can now be
constructed as a static constant, instead of needing to create a
subclass. This makes the old pattern of creating a singleton INSTANCE
both misnamed and lacking a common placement.
This commit renames Action to ActionType, thus allowing the old INSTANCE
naming pattern to be TYPE on the transport action itself. ActionType
also conveys that this class is also not the action itself, although
this change does not rename any concrete classes as those will be
removed organically as they are converted to TYPE constants.
relates #34389
The Action base class currently works for both Streamable and Writeable
response types. This commit intorduces StreamableResponseAction, for
which only the legacy Action implementions which provide newResponse()
will extend. This eliminates the need for overriding newResponse() with
an UnsupportedOperationException.
relates #34389
Given a nested structure composed of Lists and Maps, getByPath will return the value
keyed by path. getByPath is a method on Lists and Maps.
The path is string Map keys and integer List indices separated by dot. An optional third
argument returns a default value if the path lookup fails due to a missing value.
Eg.
['key0': ['a', 'b'], 'key1': ['c', 'd']].getByPath('key1') = ['c', 'd']
['key0': ['a', 'b'], 'key1': ['c', 'd']].getByPath('key1.0') = 'c'
['key0': ['a', 'b'], 'key1': ['c', 'd']].getByPath('key2', 'x') = 'x'
[['key0': 'value0'], ['key1': 'value1']].getByPath('1.key1') = 'value1'
Throws IllegalArgumentException if an item cannot be found and a default is not given.
Throws NumberFormatException if a path element operating on a List is not an integer.
Fixes#42769
This change adds the ability to attach annotative information for
classes, methods, fields, static methods, class bindings, and
instance bindings during Painless whitelisting.
Annotations are specified as @annotation or optionally as
@annotation[parameter="argument",...].
Annotations open up the ability to specify whitelist objects as
having a short name (no_import -> @no_import) or deprecated.
Long and Double ValuesSource set the current document on the script
before executing, but Bytes was missing this method call. That meant
it was possible to generate an OutOfBoundsException when using
a "value" script (field + script) on keyword or other bytes
fields.
This adds in the method call, and a few yaml tests to verify correct
behavior.
This removes the previous Painless API Doc Generator prior to contexts
existing. It has been replaced with the new doc generator that uses the
documentation rest API.
Backport of: https://github.com/elastic/elasticsearch/pull/43222
This commit replaces usages of Streamable with Writeable for the
SingleShardRequest / TransportSingleShardAction classes and subclasses of
these classes.
Note that where possible response fields were made final and default
constructors were removed.

The painless context api is internal and currently meant only for use in
generating docs. This commit moves the spec file for the api so that it
is only used by the test for this api, and not externally by any clients
building from the public rest spec.
The date_histogram accepts an interval which can be either a calendar
interval (DST-aware, leap seconds, arbitrary length of months, etc) or
fixed interval (strict multiples of SI units). Unfortunately this is inferred
by first trying to parse as a calendar interval, then falling back to fixed
if that fails.
This leads to confusing arrangement where `1d` == calendar, but
`2d` == fixed. And if you want a day of fixed time, you have to
specify `24h` (e.g. the next smallest unit). This arrangement is very
error-prone for users.
This PR adds `calendar_interval` and `fixed_interval` parameters to any
code that uses intervals (date_histogram, rollup, composite, datafeed, etc).
Calendar only accepts calendar intervals, fixed accepts any combination of
units (meaning `1d` can be used to specify `24h` in fixed time), and both
are mutually exclusive.
The old interval behavior is deprecated and will throw a deprecation warning.
It is also mutually exclusive with the two new parameters. In the future the
old dual-purpose interval will be removed.
The change applies to both REST and java clients.
Previously, TransportSingleShardAction required constructing a new
empty response object. This response object's Streamable readFrom
was used. As part of the migration to Writeable, the interface here
was updated to leverage Writeable.Reader.
relates to #34389.
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.
This change adds either ToXContentObject or ToXContentFragment to classes
directly implementing ToXContent currently. This helps in reasoning about
whether those implementations output full xcontent object or just fragments.

This moves several test classes that were part of the main root to the test root.
These were part of the main root due to limitations prior to whitelist
customization. Without whitelist customization these can be moved to a test
context and removed from the base whitelists as they should not be user
facing.
To make script_score query to have the same features
as function_score query, we need to add randomScore
function.
This function produces different
random scores on different index shards.
It is also able to produce random scores
based on the internal Lucene Document Ids.
This change allows class bindings to add as their first argument, the base script
class. The this reference to the base script class will be implicitly passed into a
class binding as the first constructor argument upon initialization when
specified as the first argument in whitelist entry for the class binding. This
allows a class binding access to additional information added to the base script
class such as more information about the current document or current shard.
One extra requirement for this to work is the appropriate script base class
must be whitelisted (should be empty).
This PR adds an internal REST API for querying context information about
Painless whitelists.
Commands include the following:
GET /_scripts/painless/_context -- retrieves a list of contexts
GET /_scripts/painless/_context?context=%name% retrieves all available
information about the API for this specific context
This fixes a bug where a String to char cast in Painless could be done implicitly.
It is now required that a String to char cast is explicit as documented in the
existing specification. This also adds char and Character casting tests.
`CreateIndexRequest#source(Map<String, Object>, ... )`, which is used when
deserializing index creation requests, accidentally accepts mappings that are
nested twice under the type key (as described in the bug report #38266).
This in turn causes us to be too lenient in parsing typeless mappings. In
particular, we accept the following index creation request, even though it
should not contain the type key `_doc`:
```
PUT index?include_type_name=false
{
"mappings": {
"_doc": {
"properties": { ... }
}
}
}
```
There is a similar issue for both 'put templates' and 'put mappings' requests
as well.
This PR makes the minimal changes to detect and reject these typed mappings in
requests. It does not address #38266 generally, or attempt a larger refactor
around types in these server-side requests, as I think this should be done at a
later time.
This test has been awaiting a fix that isn't currently relevant because incoming
lambda parameters are read-only. If this ever changes a new set of tests can
be added that are up-to-date.
This PR removes the temporary change we made to the yml test harness in #37285
to automatically set `include_type_name` to `true` in index creation requests
if it's not already specified. This is possible now that the vast majority of
index creation requests were updated to be typeless in #37611. A few additional
tests also needed updating here.
Additionally, this PR updates the test harness to set `include_type_name` to
`false` in index creation requests when communicating with 6.x nodes. This
mirrors the logic added in #37611 to allow for typeless document write requests
in test set-up code. With this update in place, we can remove many references
to `include_type_name: false` from the yml tests.
This PR attempts to remove all typed calls from our YAML REST tests. The PR adds include_type_name: false to create index requests that use a mapping and also to put mapping requests. It also removes _type from index requests where they haven't already been removed. The PR ignores tests named *_with_types.yml since this are specifically testing typed API behaviour.
The change also includes changing the test harness to add the type _doc to index, update, get and bulk requests that do not specify the document type when the test is running against a mixed 7.x/6.x cluster.
Today the routing of a SourceToParse is assigned in a separate step
after the object is created. We can easily forget to set the routing.
With this commit, the routing must be provided in the constructor of
SourceToParse.
Relates #36921
This adds implicit boxed type to boxed types casts for non-def types to create asymmetric casting relative to the def type when calling methods or returning values. This means that a user calling a method taking an Integer can call it with a Byte, Short, etc. legally which matches the way def works. This creates consistency in the casting model that did not previously exist.
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.
* 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.
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 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.
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 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`).

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.

Relates to #33309
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.
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.
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.

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

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.
