Access to special variables _source and _fields were accidentally
removed in recent refactorings. This commit adds them back, along with a
test.
closes#33884
- 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 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.
Currently the StemmerTokenFilterFactory checks the validity of the language
setting only when the first TokenStream is processed. Instead we should throw an
error earlier at mapping creation time. This change adds a check to the
StemmerTokenFilterFactory constructor that checks for a valid `language` setting
by trying to create a new TokenStream from an empty input stream. This will
throw errors about wrong language settings early on.
Closes#34170
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.
* SCRIPTING: Add Expr. Compile for TermSetQuery Ctx.
* Follow up to #33602 adding the ability to compile TermsSetQuery
scripts with the expressions engine in the same way we support
SearchScript in Expressions
* Duplicated the code here for now to make the change less complex,
the only difference to SearchScript is that `_score` and `_value` are not handled for TermsSetQuery
* remove redundant check
Optionals containing boxed primitive types are prohibitively costly because they
have two level of boxing. For Optional<Integer> the analogous OptionalInt can be
used to avoid the boxing of the contained int value.
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.
The synonym filters no longer need access to the AnalysisRegistry in their
constructors, so we can remove the special-case code and move them to the
common analysis module.
This commit means that synonyms are no longer available for `server` integration tests,
so several of these are either rewritten or migrated to the common analysis module
as rest-spec-api tests
This commit adds the ability to plug in compilation of custom contexts
in mock script engine. This is needed for testing plugins which add
custom contexts like watcher.
Currently a bad regex in CORS settings throws a PatternSyntaxException, which
then bubbles up through the bootstrap code, meaning users have to parse a
stack trace to work out where the problem is. We should instead catch this
exception and rethrow with a more useful error message.
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 commit removes the sysprop controlling whether ctx is in params for
update scripts and replaces it with use of the new ParameterMap, which
outputs a deprecation warning whenever params.ctx is used.
* INGEST: Tests for Drop Processor
* UT for behavior of dropped callback
and drop processor
* Moved drop processor to `server`
project to enable this test
* Simple IT
* Relates #32278
This commit introduces an AbstractSimpleSecurityTransportTestCase for
security transports. This classes provides transport tests that are
specific for security transports. Additionally, it fixes the tests referenced in
#33285.
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.
Drops `Settings` from some of the methods to lookup loggers and
deprecates another logger lookup that takes `Settings` because
`Settings` is no longer required to build a logger.
* ingest: support simulate with verbose for pipeline processor
This change better supports the use of simulate?verbose with the
pipeline processor. Prior to this change any pipeline processors
executed with simulate?verbose would not show all intermediate
processors for the inner pipelines.
This changes also moves the PipelineProcess and TrackingResultProcessor
classes to enable instance checks and to avoid overly public classes.
As well this updates the error message for when cycles are detected
in pipelines calling other pipelines.
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).
We currently special-case SynonymFilterFactory and SynonymGraphFilterFactory, which need to
know their predecessors in the analysis chain in order to correctly analyze their synonym lists. This
special-casing doesn't work with Referring filter factories, such as the Multiplexer or Conditional
filters. We also have a number of filters (eg the Multiplexer) that will break synonyms when they
appear before them in a chain, because they produce multiple tokens at the same position.
This commit adds two methods to the TokenFilterFactory interface.
* `getChainAwareTokenFilterFactory()` allows a filter factory to rewrite itself against its preceding
filter chain, or to resolve references to other filters. It replaces `ReferringFilterFactory` and
`CustomAnalyzerProvider.checkAndApplySynonymFilter`, and by default returns `this`.
* `getSynonymFilter()` defines whether or not a filter should be applied when building a synonym
list `Analyzer`. By default it returns `true`.
Fixes#33609
* MINOR: Drop Redundant Ctx. Check in ScriptService
* This check is completely redundant, the expression script
engine will throw anyway (and with a similar message) for
those contexts that it cannot compile. Moreover, the update context
is not the only context that is not suported by the expression engine
at this point so handling the update context separately here makes
no sense.
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.
This allows users to filter out tokens from a TokenStream using painless scripts,
instead of having to write specialised Java code and packaging it up into a plugin.
The commit also refactors the AnalysisPredicateScript.Token class so that it wraps
and makes read-only an AttributeSource.
* 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
This change collapses all metrics aggregations classes into a single package `org.elasticsearch.aggregations.metrics`.
It also restricts the visibility of some classes (aggregators and factories) that should not be used outside of the package.
Relates #22868
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
Historically we have had a ESLoggingHandler in the netty module that
logs low-level connection operations. This class just extends the netty
logging handler with some (broken) message deserialization. This commit
fixes this message serialization and moves the class to server.
This new logger logs inbound and outbound messages. Eventually, we
should move other event logging to this class (connect, close, flush).
That way we will have consistent logging regards of which transport is
loaded.
Resolves#27306 on master. Older branches will need a different fix.
This commit is related to #32517. It allows an "server_name"
attribute on a DiscoveryNode to be propagated to the server using
the TLS SNI extentsion. This functionality is only implemented for
the netty security transport.
This allows tokenfilters to be applied selectively, depending on the status of the current token in the tokenstream. The filter takes a scripted predicate, and only applies its subfilter when the predicate returns true.
We can have multiple documents in Lucene with the same seq_no for
parent-child documents (or without rollback). In this case, the usage
"lastSeenSeqNo + 1" is an off-by-one error as it may miss some
documents. This error merely affects the `skippedOperations` contract.

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.
- third party audit detects jar hell with JDK so we disable it
- jdk non portable in forbiddenapis detects classes being used from the
JDK ( for fips ) that are not portable, this is intended so we don't
scan for it on fips.
- different exclusion rules for third party audit on fips
Closes#33179
Trailers (statements following something like an if statement) that don't use brackets currently require a semicolon even if they're the last statement. This is a regression caused by (#29566) and noted by (#33193). This change fixes the regression and adds a test for the broken case.
In #29623 we added `Request` object flavored requests to the low level
REST client and in #30315 we deprecated the old `performRequest`s. In a
long series of PRs I've changed all of the old style requests that I
could find with `grep`. In this PR I change all requests that I could
find by *removing* the deprecated methods. Since this is a non-trivial
change I do not include actually removing the deprecated requests. I'll
do that in a follow up. But this should be the last set of usage
removals before the actual deprecated method removal. Yay!
* ingest: Introduce the dissect processor
The ingest node dissect processor is an alternative to Grok
to split a string based on a pattern. Dissect differs from
Grok such that regular expressions are not used to split the
string.
Dissect can be used to parse a source text field with a
simpler pattern, and is often faster the Grok for basic string
parsing. This processor uses the dissect library which
does most of the work.
We used to set `maxScore` to `0` within `TopDocs` in situations where there is really no score as the size was set to `0` and scores were not even tracked. In such scenarios, `Float.Nan` is more appropriate, which gets converted to `max_score: null` on the REST layer. That's also more consistent with lucene which set `maxScore` to `Float.Nan` when merging empty `TopDocs` (see `TopDocs#merge`).
In our Netty layer we have had to take extra precautions against Netty
catching throwables which prevents them from reaching the uncaught
exception handler. This code has taken on additional uses in NIO layer
and now in the scheduler engine because there are other components in
stack traces that could catch throwables and suppress them from reaching
the uncaught exception handler. This commit is a simple cleanup of the
iterative evolution of this code to refactor all uses into a single
method in ExceptionsHelper.
This is related to #32517. This commit passes the DiscoveryNode to the
initiateChannel method for different Transport implementation. This
will allow additional attributes (besides just the socket address) to be
used when opening channels.
This is a followup to #31886. After that commit the
TransportConnectionListener had to be propogated to both the
Transport and the ConnectionManager. This commit moves that listener
to completely live in the ConnectionManager. The request and response
related methods are moved to a TransportMessageListener. That listener
continues to live in the Transport class.
This removes def from the classes map in PainlessLookup and instead always special
cases it. This prevents potential calls against the def type that shouldn't be made and
forces all cases of def throughout Painless code to be special cased.
This is related to #31835. It moves the default connection profile into
the ConnectionManager class. The will allow us to have different
connection managers with different profiles.
This removes custom Response classes that extend `AcknowledgedResponse` and do nothing, these classes are not needed and we can directly use the non-abstract super-class instead.
While this appears to be a large PR, no code has actually changed, only class names have been changed and entire classes removed.
This changes the whitelist parameter fqn_only to no_import when specifying that a
whitelisted class must have the fully-qualified-name instead of a shortcut name. This more
closely correlates with Java imports, hence the rename.
This is related to #31835. This commit adds a connection manager that
manages client connections to other nodes. This means that the
TcpTransport no longer maintains a map of nodes that it is connected
to.
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.
