* [health] bootstrap HealthObserver from agent to API (#16141) * [health] bootstrap HealthObserver from agent to API * specs: mocked agent needs health observer * add license headers * Merge `main` into `feature/health-report-api` (#16397) * Add GH vault plugin bot to allowed list (#16301) * regenerate webserver test certificates (#16331) * correctly handle stack overflow errors during pipeline compilation (#16323) This commit improves error handling when pipelines that are too big hit the Xss limit and throw a StackOverflowError. Currently the exception is printed outside of the logger, and doesn’t even show if log.format is json, leaving the user to wonder what happened. A couple of thoughts on the way this is implemented: * There should be a first barrier to handle pipelines that are too large based on the PipelineIR compilation. The barrier would use the detection of Xss to determine how big a pipeline could be. This however doesn't reduce the need to still handle a StackOverflow if it happens. * The catching of StackOverflowError could also be done on the WorkerLoop. However I'd suggest that this is unrelated to the Worker initialization itself, it just so happens that compiledPipeline.buildExecution is computed inside the WorkerLoop class for performance reasons. So I'd prefer logging to not come from the existing catch, but from a dedicated catch clause. Solves #16320 * Doc: Reposition worker-utilization in doc (#16335) * settings: add support for observing settings after post-process hooks (#16339) Because logging configuration occurs after loading the `logstash.yml` settings, deprecation logs from `LogStash::Settings::DeprecatedAlias#set` are effectively emitted to a null logger and lost. By re-emitting after the post-process hooks, we can ensure that they make their way to the deprecation log. This change adds support for any setting that responds to `Object#observe_post_process` to receive it after all post-processing hooks have been executed.

(#16390) * Increase Jruby -Xmx to avoid OOM during zip task in DRA (#16408) Fix: #16406 * Generate Dataset code with meaningful fields names (#16386) This PR is intended to help Logstash developers or users that want to better understand the code that's autogenerated to model a pipeline, assigning more meaningful names to the Datasets subclasses' fields. Updates `FieldDefinition` to receive the name of the field from construction methods, so that it can be used during the code generation phase, instead of the existing incremental `field%n`. Updates `ClassFields` to propagate the explicit field name down to the `FieldDefinitions`. Update the `DatasetCompiler` that add fields to `ClassFields` to assign a proper name to generated Dataset's fields. * Implements safe evaluation of conditional expressions, logging the error without killing the pipeline (#16322) This PR protects the if statements against expression evaluation errors, cancel the event under processing and log it. This avoids to crash the pipeline which encounter a runtime error during event condition evaluation, permitting to debug the root cause reporting the offending event and removing from the current processing batch. Translates the `org.jruby.exceptions.TypeError`, `IllegalArgumentException`, `org.jruby.exceptions.ArgumentError` that could happen during `EventCodition` evaluation into a custom `ConditionalEvaluationError` which bubbles up on AST tree nodes. It's catched in the `SplitDataset` node. Updates the generation of the `SplitDataset `so that the execution of `filterEvents` method inside the compute body is try-catch guarded and defer the execution to an instance of `AbstractPipelineExt.ConditionalEvaluationListener` to handle such error. In this particular case the error management consist in just logging the offending Event. --------- Co-authored-by: Karen Metts <35154725+karenzone@users.noreply.github.com> * Update logstash_releases.json (#16426) * Release notes for 8.15.1 (#16405) (#16427) * Update release notes for 8.15.1 * update release note --------- Co-authored-by: logstashmachine <43502315+logstashmachine@users.noreply.github.com> Co-authored-by: Kaise Cheng <kaise.cheng@elastic.co> (cherry picked from commit 2fca7e3) Co-authored-by: github-actions[bot] <41898282+github-actions[bot]@users.noreply.github.com> * Fix ConditionalEvaluationError to do not include the event that errored in its serialiaxed form, because it's not expected that this class is ever serialized.

(cherry picked from commit bb7ecc2) Co-authored-by: Andrea Selva <selva.andre@gmail.com> * use gnu tar compatible minitar to generate tar artifact (#16432) (#16434) Using VERSION_QUALIFIER when building the tarball distribution will fail since Ruby's TarWriter implements the older POSIX88 version of tar and paths will be longer than 100 characters. For the long paths being used in Logstash's plugins, mainly due to nested folders from jar-dependencies, we need the tarball to follow either the 2001 ustar format or gnu tar, which is implemented by the minitar gem. (cherry picked from commit 69f0fa5) Co-authored-by: João Duarte <jsvd@users.noreply.github.com> * account for the 8.x in DRA publishing task (#16436) (#16440) the current DRA publishing task computes the branch from the version contained in the version.yml This is done by taking the major.minor and confirming that a branch exists with that name. However this pattern won't be applicable for 8.x, as that branch currently points to 8.16.0 and there is no 8.16 branch. This commit falls back to reading the buildkite injected BUILDKITE_BRANCH variable.

(#16489) (#16491) (cherry picked from commit fd1de39) Co-authored-by: Mashhur <99575341+mashhurs@users.noreply.github.com> * Don't use an older JRuby with oraclelinux-7 (#16499) (#16501) A recent PR (elastic/ci-agent-images/pull/932) modernized the VM images and removed JRuby 9.4.5.0 and some older versions. This ended up breaking exhaustive test on Oracle Linux 7 that hard coded JRuby 9.4.5.0. PR #16489 worked around the problem by pinning to the new JRuby, but actually we don't need the conditional anymore since the original issue jruby/jruby#7579 (comment) has been resolved and none of our releasable branches (apart from 7.17 which uses `9.2.20.1`) specify `9.3.x.y` in `/.ruby-version`. Therefore, this commit removes conditional setting of JRuby for OracleLinux 7 agents in exhaustive tests (and relies on whatever `/.ruby-version` defines).

(#16493) * DLQ-ing events that trigger an conditional evaluation error. (#16423) When a conditional evaluation encounter an error in the expression the event that triggered the issue is sent to pipeline's DLQ, if enabled for the executing pipeline. This PR engage with the work done in #16322, the `ConditionalEvaluationListener` that is receives notifications about if-statements evaluation failure, is improved to also send the event to DLQ (if enabled in the pipeline) and not just logging it.
