Currently AbstractBuilderTestCase generates certain random values in its
`beforeTest()` method annotated with @Before only the first time that a test
method in the suite is run while initializing the serviceHolder that we use for
the rest of the test. This changes the values of subsequent random values
and has the effect that when running single methods from a test suite with
"-Dtests.method=*", the random values it sees are different from when the same
test method is run as part of the whole test suite. This makes it hard to use
the reproduction lines logged on failure.
This change runs the inialization of the serviceHolder and the randomization
connected to it using the test runners master seed, so reproduction by running
just one method is possible again.
Closes#32400
This commit adds two pieces. The first is a small set of documentation providing
instructions on how to get setup to run context examples. This will require a download
similar to how Kibana works for some of the examples. The second is an ingest processor
example using the downloaded data. More examples will follow as ideally one per PR.
This also adds a set of tests to individually test each script as a unit test.
As part of #32608 we made sure that the fully qualified index name is taken from the query shard context whenever creating a new `QueryShardException`. That change introduced a regression as instead of setting the entire `Index` object to the exception, which holds index name and index uuid, we ended up setting only the index name (including cluster alias). With this commit we make sure that the index uuid does not get lost and we try to lower the chances that a similar bug makes it in another time. That's done by making `QueryShardContext` return the fully qualified `Index` (which also holds the uuid) rather than only the fully qualified index name.
This change consolidates all the logic for generating a FunctionReference (renamed from
FunctionRef) from several arbitrary constructors to a single static function that is used at
both compile-time and run-time. This increases long-term maintainability as it is much
easier to follow when and how a function reference is being generated. It moves most of
the duplicated logic out of the ECapturingFuncRef, EFuncRef and ELambda nodes and
Def as well.
This modifies Def to use a Map<String, LocalMethod> to look up user-defined methods at runtime
instead of writing constant methodhandles to do the reverse lookup. This creates a consistency
between how LocalMethods are looked up at compile-time and run-time. This consistency will allow
this code to be more maintainable moving forward. This will also allow FunctionReference to be
cleaned up in a follow up PR.
Renames existing methods in PainlessLookup. Adds lookupPainlessClass,
lookupPainlessMethod, and lookupPainlessField to PainlessLookup. This consolidates
the logic necessary to look these things up into a single place and begins the clean up of
some of the nodes that were looking each of these things up individually. This also has
the added benefit of improved consistency in error messaging.
This commit adds a boolean system property, `es.scripting.use_java_time`,
which controls the concrete return type used by doc values within
scripts. The return type of accessing doc values for a date field is
changed to Object, essentially duck typing the type to allow
co-existence during the transition from joda time to java time.
* Upgrade to `4.1.28` since the problem reported in #32487 is a bug in Netty itself (see https://github.com/netty/netty/issues/7337)
* Fixed other leaks in test code that now showed up due to fixes improvements in leak reporting in the newer version
* Needed to extend permissions for netty common package because it now sets a classloader at runtime after changes in 63bae0956a
* Adjusted forbidden APIs check accordingly
* Closes#32487
Renames and removes variables from PainlessMethod to follow the new naming
convention. Generates methodtypes at compile-time instead of using a method at run-
time. Moves write method to MethodWriter.
This commit fixes the painless compiler classloader to know about the
classes from the script context. This fixes an issue when a custom
context is used from a plugin which caused a ClassNotFoundException for
the script class and its factory classes.
PainlessMethod was being used as both a method and a constructor, and while there are
similarities, there are also some major differences. This allows the reflection objects to be
stored reducing the number of other pieces of data stored in a PainlessMethod as they are
now redundant. This temporarily increases some of the code in FunctionRef and
PainlessDocGenerator as they now differentiate between constructors and methods, BUT
is also makes the code more maintainable because there aren't checks in several places
anymore to differentiate.
The error tests for hex values previously used a random string of
digits, but this could be a valid hex value. This commit changes these
tests to use a fixed invalid hex value.
closes#32370
MethodType can be computed at compile-time rather than run-time. This removes the
method that collects MethodType at run-time from a PainlessMethod since is it no longer
necessary.
The main highlight is the removal of the reclaim_deletes_weight in the TieredMergePolicy.
The es setting index.merge.policy.reclaim_deletes_weight is deprecated in this commit and the value is ignored. The new merge policy setting setDeletesPctAllowed should be added in a follow up.
This commit changes the randomization to always create an index with a type.
It also adds a way to create a query shard context that maps to an index with
no type registered in order to explicitely test cases where there is no type.
There are two scenarios where a http request could terminate in the cors
handler. If that occurs, the requests need to be released. This commit
releases those requests.
Removes the variables name, clazz, and type as they are unnecessary. Renames
staticMembers -> staticFields, members -> fields, getters -> getterMethodHandles, and
setters -> setterMethodHandles.
Removing some dead code or supressing warnings where apropriate. Most of the
time the variable tested for null is dereferenced earlier or never used before.
Implements a static function in PainlessLookupBuilder that contains all the logic related
to Whitelist. PainlessLookupBuilder is available for use in loading from methods beyond
Whitelist now.
* Test `handler` must release buffer the same way the replaced `org.elasticsearch.http.netty4.Netty4HttpRequestHandler#channelRead0` releases it
* Closes#32289
This finishes the updating the methods in the PainlessLookupBuilder to the new naming scheme. Mechanical change. Methods include the ones used for copying members in the inheritance hierarchy, calculating shortcuts, and setting the functional interface.
This adds the ERR metric to the provided xContent parsers in the module and the
high level rest client registry. Also adding integration tests to make sure the
metric is correctly registered and usable from the client.
Adds a new single-value metrics aggregation that computes the weighted
average of numeric values that are extracted from the aggregated
documents. These values can be extracted from specific numeric
fields in the documents.
When calculating a regular average, each datapoint has an equal "weight"; it
contributes equally to the final value. In contrast, weighted averages
scale each datapoint differently. The amount that each datapoint contributes
to the final value is extracted from the document, or provided by a script.
As a formula, a weighted average is the `∑(value * weight) / ∑(weight)`
A regular average can be thought of as a weighted average where every value has
an implicit weight of `1`.
Closes#15731
The notion of "quality" is an overloaded term in the search ranking evaluation
context. Its usually used to decribe certain levels of "good" vs. "bad" of a
seach result with respect to the users information need. We currently report the
result of the ranking evaluation as `quality_level` which is a bit missleading.
This changes the response parameter name to `metric_score` which fits better.
This is largely mechanical change that cleans up the addConstructor, addMethod, and
addFields methods in PainlessLookup. Changes include renamed variables, better error
messages, and some minor code movement to make it more maintainable long term.
* INGEST: Extend KV Processor (#31789)
Added more capabilities supported by LS to the KV processor:
* Stripping of brackets and quotes from values (`include_brackets` in corresponding LS filter)
* Adding key prefixes
* Trimming specified chars from keys and values
Refactored the way the filter is configured to avoid conditionals during execution.
Refactored Tests a little to not have to add more redundant getters for new parameters.
Relates #31786
* Add documentation
* INGEST: Make a few Processors callable by Painless
* Extracted a few stateless String processors as well as the json processor to static methods and whitelisted them in Painless
* provide whitelist from processors plugin
Currently the ranking evaluation response contains a 'unknown_docs' section
for each search use case in the evaluation set. It contains document ids for
results in the search hits that currently don't have a quality rating.
This change renames it to `unrated_docs`, which better reflects its purpose.
This removes some extraneous naming syntax and makes clear the meaning of certain
naming conventions without ambiguities (stricter) within the lookup package. Purely
mechanical change. Note this does not cover a large portion of the
PainlessLookupBuilder and PainlessLookup yet as there are several more follow up PRs for these incoming.
* Add basic support for field aliases in index mappings. (#31287)
* Allow for aliases when fetching stored fields. (#31411)
* Add tests around accessing field aliases in scripts. (#31417)
* Add documentation around field aliases. (#31538)
* Add validation for field alias mappings. (#31518)
* Return both concrete fields and aliases in DocumentFieldMappers#getMapper. (#31671)
* Make sure that field-level security is enforced when using field aliases. (#31807)
* Add more comprehensive tests for field aliases in queries + aggregations. (#31565)
* Remove the deprecated method DocumentFieldMappers#getFieldMapper. (#32148)
This change cleans up the addPainlessClass methods by doing the following things:
* Rename many variable names to match the new conventions described in the JavaDocs
for PainlessLookup
* Decouples Whitelist.Class from adding a PainlessClass directly
* Adds a second version of addPainlessClass that is intended for use to add future
defaults in a follow PR
This change also fixes the method and field caches by storing Classes instead of Strings
since it would technically be possible now that the whitelists are extendable to have
different Classes with the same name. It was convenient to add this change together
since some of the new constants are shared.
Note the changes are largely mechanical again where all the code behavior should
remain the same.
When building custom tokenfilters without an index in the _analyze endpoint,
we need to ensure that referring filters are correctly built by calling
their #setReferences() method
