This commit adds an optional `context` url parameter to the put stored
script request. When a context is specified, the script is compiled
against that context before storing, as a validation the script will
work when used in that context.
ScriptContexts currently understand a FactoryType that can produce
instances of the script InstanceType. However, for search scripts, this
does not work as we have the concept of LeafSearchScript that is created
per lucene segment. This commit effectively renames the existing
SearchScript class into SearchScript.LeafFactory, which is a new,
optional, class that can be defined within a ScriptContext.
LeafSearchScript is effectively renamed back into SearchScript. This
change allows the model of stateless factory -> stateful factory ->
script instance to continue, but in a generic way that any script
context may take advantage of.
relates #20426
This commit renames the concept of the "compiled type" to a "factory
type", along with all implementations of this class to be named Factory.
This brings it inline with the classes purpose.
This commit adds collection of all contexts to the parameters of
getScriptEngine. This will allow script engines like painless to
precache extra information about the contexts.
This is a simple refactoring to move the context definitions into the
type that they use. While we have multiple context names for the same
class at the moment, this will eventually become one ScriptContext per
instance type, so the pattern of a static member on the interface called
CONTEXT can be used. This commit also moves the consolidated list of
contexts provided by core ES into ScriptModule.
This commit changes the compile method of ScriptEngine to be generic in
the same way it is on ScriptService. This moves the shim of handling the
two existing context classes into each script engine, so that each
engine can be worked on independently to convert to real handling of
contexts.
This commit modifies the compile method of ScriptService to be context
aware. The ScriptContext is now a generic class which contains both the
instance type and compiled type for a script. Instance type may be
stateful (for example, pre loading field information for the index a
script will execute on, like in expressions), while the compiled type is
stateless and used to construct instance type instances. This change is
only a first step to cutover ScriptService to the new paradigm. It only
converts callers to the script service, and has a small shim to wrap
compilation from the script engines to support the current two fixed
instance types, SearchScript and ExecutableScript.
Since groovy was removed, we no longer have any ScriptEngines with
resources to release. We may want to keep the option open for a script
engine to close resources, but this would not be common. This commit
adds a default implementation to ScriptEngine for `close()` to reduce
the boiler plate that must be added for a ScriptEngine implementation.
As we work towards contexts implying the return type of compilation, we
first need ScriptContext to not be an enum. This commit removes the
Standard enum and Plugin subclass of ScriptContext.
ScriptEngine implementations have an overridable method to indicate they
are safe to use as inline scripts. Since groovy was removed fro 6.0,
there are no longer any implementations which used the default false
value. Furthermore, the value was not actually read anywhere. This
commit removes the method. The ScriptEngineRegistry was also no longer
necessary as it only was used to build a map from language to engine.
This commit renames all rest test files to use the .yml extension
instead of .yaml. This way the extension used within all of
elasticsearch for yaml is consistent.
When constructing an array list, if we know the size of the list in
advance (because we are adding objects to it derived from another list),
we should size the array list to the appropriate capacity in advance (to
avoid resizing allocations). This commit does this in various places.
Relates #24439
This commit renames ScriptEngineService to ScriptEngine. It is often
confusing because we have the ScriptService, and then
ScriptEngineService implementations, but the latter are not services as
we see in other places in elasticsearch.
This adds `-XX:-OmitStackTraceInFastThrow` to the JVM arguments
which *should* prevent the JVM from omitting stack traces on
common exception sites. Even though these sites are common, we'd
still like the exceptions to debug them.
This also adds the flag when running tests and adapts some tests
that had workarounds for the absense of the flag.

Replaces LambdaMetaFactory with LambdaBootstrap, a custom solution for lambdas in Painless using a design similar to LambdaMetaFactory, but allows for custom adaptation of types which recent changes to LambdaMetaFactory no longer allowed.
`script_stack` is super useful when debugging Painless scripts
because it skips all the "weird" stuff involved that obfuscates
where the actual error is. It skips Painless's internals and
call site bootstrapping.
It works fine, but it didn't have many tests. This converts a
test that we had for line numbers into a test for the
`script_stack`. The line numbers test was an indirect test
for `script_stack`.
This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.
closes#20240
We'd like to be able to support context-sensitive whitelists in
Painless but we can't now because the whitelist is a static thing.
This begins to de-static the whitelist, in particular removing
the static keyword from most of the methods on `Definition` and
plumbing the static instance into the appropriate spots as though
it weren't static. Once we de-static all the methods we should be
able to fairly simply build context-sensitive whitelists.
The only "fun" bit of this is that I added another layer in the
chain of methods that bootstraps `def` calls. Instead of running
`invokedynamic` directly on `DefBootstrap` we now `invokedynamic`
`$bootstrapDef` on the script itself loads the `Definition` that
the script was compiled against and then calls `DefBootstrap`.
I chose to put `Definition` into `Locals` so I didn't have to
change the signature of all the `analyze` methods. I could have
do it another way, but that seems ok for now.
The JVM caches `Integer` objects. This is known. A test in Painless
was relying on the JVM not caching the particular integer `1000`.
It turns out that when you provide `-XX:+AggressiveOpts` the JVM
*does* cache `1000`, causing the test to fail when that is
specified.
This replaces `1000` with a randomly selected integer that we test
to make sure *isn't* cached by the JVM. *Hopefully* this test is
good enough. It relies on the caching not changing in between when
we check that the value isn't cached and when we run the painless
code. The cache now is a simple array but there is nothing
preventing it from changing. If it does change in a way that thwarts
this test then the test fail fail again. At least when that happens
the next person can see the comment about how it is important
that the integer isn't cached and can follow that line of inquiry.

This commit skips the two Painless tests
EqualsTests#testBranchEqualsDefAndPrimitive and

This commit renames the random ASCII helper methods in ESTestCase. This

The current rest backcompat tests, which run against a mixed cluster of
5.x and 6.0 nodes, depend on snapshot builds of 5.x. However, this has
the potential for inconsistency that results in CI failures, and happens
quite often, whenever some backcompat logic is added to 5.x, but the bwc
test on master fails because the 5.x code has not yet been published as
a snapshot.
This change creates a git clone of the 5.x branch,
builds the zip distribution, and ties that into gradle substitutions for
the 5.x version.
Without this change, if write a script with multiple regexes
*sometimes* the lexer will decide to look at them like one
big regex and then some trailing garbage. Like this discuss post:
https://discuss.elastic.co/t/error-with-the-split-function-in-painless-script/79021
```
def val = /\\\\/.split(ctx._source.event_data.param17);
if (val[2] =~ /\\./) {
def val2 = /\\./.split(val[2]);
ctx._source['user_crash'] = val2[0]
} else {
ctx._source['user_crash'] = val[2]
}
```
The error message you get from the lexer is `lexer_no_viable_alt_exception`
right after the *second* regex.
With this change each regex is just a single regex like it ought to be.
As a bonus, while looking into this issue I found that the error
reporting for regexes wasn't very nice. If you specify an invalid
pattern then you get an error marker on the start of the pattern
with the JVM's regex error message which attempts to point you to the
location in the regex but is totally unreadable in the JSON response.
This change fixes the location to point to the appropriate spot
inside the pattern and removes the portion of the JVM's error message
that doesn't render well. It is no longer needed now that we point
users to the appropriate spot in the pattern.
This commit mutes a ton of Painless lambda tests on JDK 9. This commit

just blanket muted all tests in LambdaTests, FunctionRefTests, and
AugmentationTests.

Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).
This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`. The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.
Fixes Painless to properly implement scripts that return primitives
and void. Adds some simple tests that we emit sane opcodes and some
other tests that we implement primitives as expected.
Mostly this is just a fix following up from #22983 but there is one
thing I did really worth talking about, I think. So, before this script
Painless scripts could only ever return Object and they did would always
return null for paths that didn't return any values. Now that they
can return primitives the question is "what should Painless return
from paths that don't return any values?" And I answered that with
"whatever the JLS default value is". So 0/0L/0f/0d/false.
Generalizes three previously hard coded things in painless into
generic concepts:
1. The "main method" is no longer hardcoded to:
```
public abstract Object execute(Map<String, Object> params,
Scorer scorer, LeafDocLookup doc, Object value);
```
Instead Painless's compiler takes an interface and implements it. It looks like:
```
public interface SomeScript {
// Argument names we expose to Painless scripts
String[] ARGUMENTS = new String[] {"a", "b"};
// Method implemented by Painless script. Must be named execute but can have any parameters or return any value.
Object execute(String a, int b);
// Is the "a" argument used by the script?
boolean uses$a();
}
SomeScript script = scriptEngine.compile(SomeScript.class, null, "the_script_here", emptyMap());
Object result = script.execute("a", 1);
```
`PainlessScriptEngine` now compiles all scripts to the new
`GenericElasticsearchScript` interface by default for compatibility
with the rest of Elasticsearch until it is able to use this new
ability.
2. `_score` and `ctx` are no longer hardcoded to be extracted from
`#score` and `params` respectively. Instead Painless's default
implementation of Elasticsearch scripts uses the `uses$_score` and
`uses$ctx` methods to determine if it is used and gives them
dummy values if they are not used.
3. Throwing the `ScriptException` is now handled by the Painless
script itself. That way Painless doesn't have to leak the metadata
that is required to build the fancy stack trace. And all painless scripts
get the fancy stack trace.
Today all search phases are inner classes of AbstractSearchAsyncAction or one of it's
subclasses. This makes unit testing of these classes practically impossible. This commit
Extracts `DfsQueryPhase` and `FetchSearchPhase` or of the code that composes the actual
query execution types and moves most of the fan-out and collect code into an `InitialSearchPhase`
class that can be used to build initial search phases (phases that retry on shards). This will
make modification to these classes simpler and allows to easily compose or add new search phases
down the road if additional roundtrips are required.
Painless can cast anything into the magic type `def` but it
really shouldn't try to cast **nothing** into `def`. That causes
the byte code generation library to freak out a little.

We were incorrectly resolving qualified method references at run

Implemented by wrapping an array of reused `ModuleDateTime`s that
we grow when needed. The `ModuleDateTime`s are reused when we
move to the next document.
Also improves the error message returned when attempting to modify
the `ScriptdocValues`, removes a couple of allocations, and documents
that the date functions are available in Painless.

Currently, stored scripts use a namespace of (lang, id) to be put, get, deleted, and executed. This is not necessary since the lang is stored with the stored script. A user should only have to specify an id to use a stored script. This change makes that possible while keeping backwards compatibility with the previous namespace of (lang, id). Anywhere the previous namespace is used will log deprecation warnings.
The new behavior is the following:
When a user specifies a stored script, that script will be stored under both the new namespace and old namespace.
Take for example script 'A' with lang 'L0' and data 'D0'. If we add script 'A' to the empty set, the scripts map will be ["A" -- D0, "A#L0" -- D0]. If a script 'A' with lang 'L1' and data 'D1' is then added, the scripts map will be ["A" -- D1, "A#L1" -- D1, "A#L0" -- D0].
When a user deletes a stored script, that script will be deleted from both the new namespace (if it exists) and the old namespace.
Take for example a scripts map with {"A" -- D1, "A#L1" -- D1, "A#L0" -- D0}. If a script is removed specified by an id 'A' and lang null then the scripts map will be {"A#L0" -- D0}. To remove the final script, the deprecated namespace must be used, so an id 'A' and lang 'L0' would need to be specified.
When a user gets/executes a stored script, if the new namespace is used then the script will be retrieved/executed using only 'id', and if the old namespace is used then the script will be retrieved/executed using 'id' and 'lang'
Adds "Appending B. Painless API Reference", a reference of all classes
and methods available from Painless. Removes links to java packages
because they contain methods that we don't expose and don't contain
methods that we do expose (the ones in Augmentation). Instead this
generates a list of every class and every exposed method using the same
type information available to the
interpreter/compiler/whatever-we-call-it. From there you can jump to
the relevant docs.
Right now you build all the asciidoc files by running
```
gradle generatePainlessApi
```
These files are expected to be committed because we build the docs
without running `gradle`.
Also changes the output of `Debug.explain` so that it is easy to
search for the class in the generated reference documentation.
You can also run it in an IDE safely if you pass the path to the
directory in which to generate the docs as the first parameter. It'll
blow away the entire directory an recreate it from scratch so be careful.
And then you can build the docs by running something like:
```
../docs/build_docs.pl --out ../built_docs/ --doc docs/reference/index.asciidoc --open
```
That is, if you have checked out https://github.com/elastic/docs in
`../docs`. Wait a minute or two and your browser will pop open in with
all of Elasticsearch's reference documentation. If you go to
`http://localhost:8000/painless-api-reference.html` you can see this
list. Or you can get there by following the links to `Modules` and
`Scripting` and `Painless` and then clicking the link in the paragraphs
below titled `Appendix B. Painless API Reference`.
I like having these in asciidoc because we can deep link to them from the
rest of the guide with constructs like
`<<painless-api-reference-Object-hashCode-0>>` and
`<<painless-api-reference->>` and we get link checking. Then the only
brittle link maintenance bit is the link generation for javadoc. Which
sucks. But I think it is important that we link to the methods directly
so they are easy to find.

We don't want to expose `String#getBytes` which is required for
`Base64.getEncoder.encode` to work because we're worried about

such that:
`someString == someString.encodeBase64().decodeBase64()`.
Both methods work with the UTF-8 encoding of the string.

If a bug occurs in painless compilation (not from a user, but from the
painless infrastructure), a VerifyError may be thrown when compiling the
broken generated class. This commit wraps VerifyErrors in
ScriptException so that useful information is returned to the user,
which can be passed on to the ES team for analysis.
This bug would cause a VerifyError when scripts using the === operator
were comparing a def type against a primitive type since the primitive
type wasn't being appropriately boxed.
NOTE: The result of `?.` and `?:` can't be assigned to primitives. So
`int[] someArray = null; int l = someArray?.length` and
`int s = params.size ?: 100` don't work. Do
`def someArray = null; def l = someArray?.length` and
`def s = params.size ?: 100` instead.

You can use `Debug.explain(someObject)` in painless to throw an

Closes#20263
This should make debugging painless' analysis and code generation a
little easier.
The `toString` implementations mirror the AST somewhat, and look like
`(SSource (SReturn (ENumeric 1)))`.
Implements a null coalescing operator in painless that looks like `?:`. This form was chosen to emulate Groovy's `?:` operator. It is different in that it only coalesces null values, instead of Groovy's `?:` operator which coalesces all falsy values. I believe that makes it the same as Kotlin's `?:` operator. In other languages this operator looks like `??` (C#) and `COALESCE` (SQL) and `:-` (bash).
This operator is lazy, meaning the right hand side is only evaluated at all if the left hand side is null.
This adds support to painless for decimal constants with trailing `d` or
`D` to make it compatible with Java. It already supported integer
constants with a trailing `d` or `D` but this adds tests for it.
Closes#21116
In painless we prefer explicit types over implicit ones whereas
groovy is the other way around. Take this groovy code:
```
> 86400000.class
java.lang.Integer
> 864000000000.class
java.lang.Long
```
Painless accepts `86400000` just fine because that is a valid `int`
in the jvm. It rejects `864000000000` as an invlid `int` constant
because, in painless as in java, `long` constants always end in `L`
or `l`.
To ease the transition from groovy to painless, this changes the
compilation error returned from these invalid constants from:
```
Invalid int constant [864000000000].
```
to
```
Invalid int constant [864000000000]. If you want a long constant then change it to [864000000000L].
```
Inspired by #21313
Null safe dereferences make handling null or missing values shorter.
Compare without:
```
if (ctx._source.missing != null && ctx._source.missing.foo != null) {
ctx._source.foo_length = ctx.source.missing.foo.length()
}
```
To with:
```
Integer length = ctx._source.missing?.foo?.length();
if (length != null) {
ctx._source.foo_length = length
}
```
Combining this with the as of yet unimplemented elvis operator allows
for very concise defaults for nulls:
```
ctx._source.foo_length = ctx._source.missing?.foo?.length() ?: 0;
```
Since you have to start somewhere, we started with null safe dereferenes.
Anyway, this is a feature borrowed from groovy. Groovy allows writing to
null values like:
```
def v = null
v?.field = 'cat'
```
And the writes are simply ignored. Painless doesn't support this at this
point because it'd be complex to implement and maybe not all that useful.
There is no runtime cost for this feature if it is not used. When it is
used we implement it fairly efficiently, adding a jump rather than a
temporary variable.
This should also work fairly well with doc values.
At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.
Java 9's exception message when lists have an out of bounds index
is much better than java 8 but the painless code asserted on the
java 8 message. Now it'll accept either.
I'm tempted to weaken the assertion but I like asserting that the
message is readable.
Adds support for indexing into lists and arrays with negative
indexes meaning "counting from the back". So for if
`x = ["cat", "dog", "chicken"]` then `x[-1] == "chicken"`.
This adds an extra branch to every array and list access but
some performance testing makes it look like the branch predictor
successfully predicts the branch every time so there isn't a
in execution time for this feature when the index is positive.
When the index is negative performance testing showed the runtime
is the same as writing `x[x.length - 1]`, again, presumably thanks
to the branch predictor.
Those performance metrics were calculated for lists and arrays but
`def`s get roughly the same treatment though instead of inlining
the test they need to make a invoke dynamic so we don't screw up
maps.
Closes#20870
* Scripting: Add support for booleans in scripts
Since 2.0, booleans have been represented as numeric fields (longs).
However, in scripts, this is odd, since you expect doing a comparison
against a boolean to work. While languages like groovy will auto convert
between booleans and longs, painless does not.
This changes the doc values accessor for boolean fields in scripts to
return Boolean objects instead of Long objects.
closes#20949
* Make Booleans final and remove wrapping of `this` for getValues()
Some objects like maps, iterables or arrays of objects can self-reference themselves. This is mostly due to a bug in code but the XContentBuilder should be able to detect such situations and throws an IllegalArgumentException instead of building objects over and over until a stackoverflow occurs.
closes#20540closes#19475
Update scripts might want to update the documents `_timestamp` but need a notion of `now()`.
Painless doesn't support any notion of now() since it would make scripts non-pure functions. Yet,
in the update case this is a valid value and we can pass it with the context together to allow the
script to record the timestamp the document was updated.
Relates to #17895
When compiling many dynamically changing scripts, parameterized
scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)
should be preferred. This enforces a limit to the number of scripts that
can be compiled within a minute. A new dynamic setting is added -
`script.max_compilations_per_minute`, which defaults to 15.
If more dynamic scripts are sent, a user will get the following
exception:

This also fixes a bug in `ScriptService` where requests being executed
concurrently on a single node could cause a script to be compiled
multiple times (many in the case of a powerful node with many shards)
due to no synchronization between checking the cache and compiling the
script. There is now synchronization so that a script being compiled
will only be compiled once regardless of the number of concurrent
searches on a node.

This makes it obvious that these tests are for running the client yaml

URIs are OK. So we use an absolute path which should resolve to the
appropriate location.
Closes#19079
This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
These are useful methods in groovy that give you control over
the replacements used:
```
'the quick brown fox'.replaceAll(/[aeiou]/,
m -> m.group().toUpperCase(Locale.ROOT))
```
