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.

`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.

Watcher still exposes some dates as joda DateTime objects. This commit
adds back joda to the painless whitelist so they can still be accessed.

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
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.

Access to special variables _source and _fields were accidentally
removed in recent refactorings. This commit adds them back, along with a
test.

- Restrict visibility of Aggregators and Factories
- Move PipelineAggregatorBuilders up a level so it is consistent with
AggregatorBuilders
- Checkstyle line length fixes for a few classes
- Minor odds/ends (swapping to method references, formatting, etc)
This removes the extraneous check to see if the class for a statically imported
method is already whitelisted, so a statically imported method can be whitelisted
independently.
Since all calls to `ESLoggerFactory` outside of the logging package were
deprecated, it seemed like it'd simplify things to migrate all of the
deprecated calls and declare `ESLoggerFactory` to be package private.
This does that.
When a script uses the special-cased SearchScript or ExecutableScript, Painless is
internally caching the GenericElasticsearchScript that is generated via compile as part of
the newInstance method for the factories. This breaks the model for class bindings as the
class binding expects to not have any stored information for each instance generated via
newInstance from the factory. This change fixes the issue by creating a new instance of
the GenericElasticsearchScript each time newInstance is called against the factory.
It is sometimes desirable to pass a class into a script constructor that
will not actually be exposed in the script whitelist. This commit uses
reflection when creating the compiler to find all the classes of the
factory method signature, and make the classloader that wraps lookup
also expose these classes.
* Adds equals/hashcode methods to the Painless* objects within the lookup package.
* Changes the caches to use the Painless* objects as keys as well as values. This forces
future changes to taken into account the appropriate values for caching.
* Deletes the existing caching objects in favor of Painless* objects. This removes a pair of
bugs that were not taking into account subtle corner cases related to augmented methods
and caching.
* Uses the Painless* objects to check for equivalency in existing Painless* objects that
may have already been added to a PainlessClass. This removes a bug related to return
not being appropriately checked when adding methods.
* Cleans up several error messages.
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 change adds the OneStatementPerLineCheck to our checkstyle precommit
checks. This rule restricts the number of statements per line to one. The
resoning behind this is that it is very difficult to read multiple statements on
one line. People seem to mostly use it in short lambdas and switch statements in
our code base, but just going through the changes already uncovered some actual
problems in randomization in test code, so I think its worth it.
With the upcoming instance bindings, the singular *Binding name isn't descriptive enough
with multiple binding types. This renames the existing *Binding classes to *ClassBinding.
Mechanical change (with some error messages changed from binding to class binding by
hand).
This commit switches the joda time backcompat in scripting to use
augmentation over ZonedDateTime. The augmentation methods provide
compatibility with the missing methods between joda's DateTime and
java's ZonedDateTime. Due to getDayOfWeek returning an enum in the java
API, ZonedDateTime is wrapped so that the method can return int like the
joda time does. The java time api version is renamed to
getDayOfWeekEnum, which will be kept through 7.x for compatibility while
users switch back to getDayOfWeek once joda compatibility is removed.
* LeafCollector.setScorer() now takes a Scorable
* Scorers may not have null Weights
* IndexWriter.getFlushingBytes() reports how much memory is being used by IW threads writing to disk
The main benefit of the upgrade for users is the search optimization for top scored documents when the total hit count is not needed. However this optimization is not activated in this change, there is another issue opened to discuss how it should be integrated smoothly.
Some comments about the change:
* Tests that can produce negative scores have been adapted but we need to forbid them completely: #33309Closes#32899
When the change was made to the format for in the whitelist for bindings, parameters from
both the constructor and the method were combined into a single list instead of separate
lists. The check for method parameters was being executed from the start of the combined
list rather than the correct position. The tests for bindings used a constructor and a method
that only used the int types so this was not caught. The test has been changed to also use
a double type and this issue is fixed.
