This commit fixes a ClassCastException which happens when
a plugin has the `enable_metric` setting set to false - a
NullMetricExt is assumed, but that is only created when
'metric.collect' is set to 'false' in the Logstash configuration,
not when an individual plugin disables its metrics.
Fixes#10538
There are several scenarios in which we can trigger concurrent convergence in
the agent, resulting in two or more threads working to perform interleaved and
potentially conflicting or overlapping pipeline actions. Notably, our trap on
`SIGHUP` will be resolved in its own thread, so if we are sent `SIGHUP` while
in the process of converging, the second in-flight convergence may get its
starting state before, during, or after the effects of the first convergence.
By mutually excluding execution of the convergence cycle, we eliminate the
class of bugs in which one convergence acquires actions that cannot succeed due
to the prior success of actions given to the other convergence.
Fixes#10537
Fixes a crash that occurs on pipeline load and/or reload when using both the
java keystore and the multi-pipeline feature, when more than one pipeline
references `${}`-style variables.
Fixes#10408
fpm requires json 1.x but the artifact rake tasks
will activate the default gem json 2
This PR ensures json 1 is activated early and is present right after
jruby is bootstrapped.
Also downgrades fpm to 1.3 as 1.11.0 wasn't building correctly
Downgrades .ruby-version to a version we have available in CI
Fixes#10396
if we send `Agent#stop_webserver` while `Agent#start_webserver` is
executing, we risk the `@webserver_thread` being nil and getting a
`NoMethodError`.
Fixes#10393
* bump jruby to 9.2
* don't rely on logstash-base docker image
* work around webmock ruby 2.5 support
* ensure data folder exists in docker
* change fixnum and bignum to integer
* FileUtils.rmdir to rm_rf
this is because from 2.3 to 2.5 FileUtils.rmdir will throw an exception
if the directory isn't empty. On 2.3 the operation will just not delete
the directory silently.
* bump jruby to 9.2.5.0 and fix test
* make rake default task since prepare pack needs it
* Resolve compiler warnings (#10247)
There are 3 types of compiler warnings that are either resolved or suppressed:
1. Rawtypes: In JRuby 9.2, `RubyArray` is a generic, so references throughout
our codebase to the now "raw" type trigger warnings. In most cases we cannot
actually resolve the issue, since the JRuby-provided methods for creating
`RubyArray`s still return the raw type, so these have been suppressed.
2. Deprecations:
- `RubyString#intern19()` -> `RubyString#intern()`
- `RubyString#downcase19(ThreadContext)` -> `RubyString#downcase(ThreadContext)`
- `NativeException`: remove import & reference directly; suppress usage
warnings
- `RaiseException()`: migrate to equivalent non-deprecated methods wherever
possible; in some cases where we are using this in conjunction with the
also-deprecated `NativeException` to preserve java stacktraces, there
seems to be no non-deprecated path forward, so these cases have been
suppressed.
3. Redundant Casts
- Resolved
* JRuby 9.2 bundler shenanigans (#10266)
* Revert "Revert "remove forced dependency on old bundler (#9395)""
This reverts commit bef984143d.
* plugin management: update internal bundler to 1.17.x APIs
* deps: update dev dependency webmock to version compatible with JRuby 9.2
* spec: update Pack fixture to include manticore version that doesn't conflict
* build: update gradle to version that has Java 11 support
* java11: resolve or suppress deprecation warnings
* Remove superfluous flag opting into ParNew GC implementation
When opting into CMS garbage collector with `XX:+UseConcMarkSweepGC`, the
young generation collector ParNew has been the default since Java 8, making
the `XX:+UseParNew` flag redundant; the flag was removed in Java 9, and
should no longer be specified to work with modern Javas.

* spec: set thread name to example description for easier debugging
* spec: prevent errors in testing specs by checking against skip list before using
* no-op: remove use of `HashMap#computeIfAbsent` on single-threaded code

* qa: by default, run integration against Elastic Stack 6.5.x
To support development on Logstash on top of Java 11, default to testing
against an Elastic Stack that is capable of running on Java 11.
* qa: ignore deprecation warnings when comparing offline pack output
* qa: add Java 9+ support to ChildProcess dev dependency
this can safely be removed when the childprocess gem supports Java9+
https://github.com/enkessler/childprocess/pull/141
* qa: allow connections to localhost in webmock
* bump jrjackson version
* fix filebeat integration tests
* spec: ensure license compliance spec runs first
The license compliance spec that validates the licenses of bundled
plugins appears to not be compatible with the hooks that we inject
into bundler for plugin management, and will fail in obscure ways
when run after those hooks have been added. Since those hooks are
not necessary for validating licenses, the easiest solution was to
ensure that those specs run first, before the VM has been poluted.
Since the gradle/junit/rspec bridge that is currently in place
runs all specs in the same JVM, we also need to make sure that the
rspec "world" is reset before a run, to ensure that it doesn't
retain spec definitions from previous runs.
Also updates the rake invocation, although I'm not sure it is used
any more.
if a plugin author defines a config parameter as:
config :retryable_codes, :validate => :number, :list => true, :default => [429]
And a user configures the plugin as:
plugin { retryable_codes => [] }
It's expected that the retryable_codes parameter is an empty array and not a nil object
This PR changes this behaviour to generate an empty array
Fixes#10179
* Add VERSION_QUALIFIER support for use by release manager
* Make the gem build processes aware of the version qualifier
* Try debugging xpack ci test failure.
* Try to use the artifacts-api.elastic.co api for ES download.
* It builds/tests locally now.
* add some comments explaining the artifacts-api and the version string
* cahnges requested in review.
