I did a little digging. It looks like IOException is thrown when the other
side closes its connection while we're waiting on our buffer to fill up. We
totally expect that in this test. It feels to me like we should throw a
`ConnectionClosedException` but upstream does not agree:
https://issues.apache.org/jira/browse/HTTPASYNC-134
While we *could* catch the exception and transform it ourselves that
seems like a bigger change than is merited at this point.
Closes#29136
Currently we store the indices specified in the request URL together with all
the other ranking evaluation specification in RankEvalSpec. This is not ideal
since e.g. the indices are not rendered to xContent and so cannot be parsed
back. Instead we should keep them in RankEvalRequest.
This commit (which will be reverted soon) adds logging on the output of
starting Wildfly. This is needed to debug an issue with Wildfly not
starting in CI.
* Decouple XContentBuilder from BytesReference
This commit removes all mentions of `BytesReference` from `XContentBuilder`.
This is needed so that we can completely decouple the XContent code and move it
into its own dependency.
While this change appears large, it is due to two main changes, moving
`.bytes()` and `.string()` out of XContentBuilder itself into static methods
`BytesReference.bytes` and `Strings.toString` respectively. The rest of the
change is code reacting to these changes (the majority of it in tests).

I have long wanted an actual test that dying with dignity works. It is
tricky because if dying with dignity works, it means the test JVM dies
which is usually an abnormal condition. And anyway, how does one force a
fatal error to be thrown. I was motivated to investigate this again by
the fact that I missed a backport to one branch leading to an issue
where Elasticsearch would not successfully die with dignity. And now we
have a solution: we install a plugin that throws an out of memory error
when it receives a request. We hack the standalone test infrastructure
to prevent this from failing the test. To do this, we bypass the
security manager and remove the PID file for the node; this tricks the
test infrastructure into thinking that it does not need to stop the
node. We also bypass seccomp so that we can fork jps to make sure that
Elasticsearch really died. And to be extra paranoid, we parse the logs
of the dead Elasticsearch process to make sure it died with
dignity. Never forget.
This commit removes the ability to specify that a plugin requires the
keystore and instead creates the keystore on package installation or
when Elasticsearch is started for the first time. The reason that we opt
to create the keystore on package installation is to ensure that the
keystore has the correct permissions (the package installation scripts
run as root as opposed to Elasticsearch running as the elasticsearch
user) and to enable removing the keystore on package removal if the
keystore is not modified.
This commit makes the controller spawner also look under modules. It
also fixes a bug in module security policy loading where the module is a
meta plugin.
Applying the rest test gradle plugin already uses the zip distribution
by default, so specifying it explicitly is not necessary. These are
leftovers from before zip was the default for rest tests.
Add support version and version_type in ingest pipelines
Add support for setting document version and version type in set
processor of an ingest pipeline.
Nodes are reusing task ids after restart. So in some rare circumstances
the same task id might be assigned to the reindexing task stored by the
old cluster and the new task that is trying to retrieve the task
results. As a result, the get task request can timeout waiting on
itself. Since we already waited for the task to finish before restarting
the cluster, waiting for the task here doesn't make any sense to start
with.
Fixes#28732
* Remove log4j dependency from elasticsearch-core
This removes the log4j dependency from our elasticsearch-core project. It was
originally necessary only for our jar classpath checking. It is now replaced by
a `Consumer<String>` so that the es-core dependency doesn't have external
dependencies.
The parts of #28191 which were moved in conjunction (like `ESLoggerFactory` and
`Loggers`) have been moved back where appropriate, since they are not required
in the core jar.
This is tangentially related to #28504
* Add javadocs for `output` parameter
* Change @code to @link
Previously a user could set a custom config path to a relative directory
using ES_PATH_CONF. In a previous change related to enabling GC logging
by default, we forced the working directory for Elasticsearch to be
ES_HOME. This had the impact of causing all relative paths to be
relative to ES_HOME, against the intent of the user. This commit
addresses this by making ES_PATH_CONF absolute before we switch the
working directory to ES_HOME.

When we submit a task to a thread pool for asynchronous execution, we
are returned a future. Since we submitted to go asynchronous, these
futures are not inspected for failure (we would have to block a thread
to do that). While we have on failure handlers for exceptions that are
thrown during execution, we do not handle throwables that are not
exceptions and these end up silently lost. This commit adds a check
after the runnable returns that inspects the status of the future. If an
unhandled throwable occurred during execution, this throwable is
propogated out where it will land in the uncaught exception handler.

[TEST] packaging: function to collect debug info
Sometimes when packaging tests fail in CI the test logs aren't enough to
tell what went wrong. This routine helps collect more info about the
state of the es installation at failure time
Generalizing BWC building so that there is less code to modify for a release. This ensures we do not
need to think about what major or minor version is in the gradle code. It follows the general rules of the
elastic release structure. For more information on the rules, see the VersionCollection's javadoc.
This also removes the additional bwc snapshots that will never be released, such as 6.0.2, which were
being built and tested against every time we ran bwc tests.
Additionally, it creates 4 new projects that correspond to the different types of snapshots that may exist
for a given version. Its possible to now run those individual tasks to work out bwc logic whereas
previously it was impossible and the entire suite of bwc tests had to be run to work out any logic
changes in the build tools' bwc project. Please note that if the project does not make sense for the
version that is current, that an error will be thrown from that individual project if an attempt is made to
run it.
This should allow for automating the version bumps as well, since it removes all the hardcoded version
logic from the configs.
Currently meta plugins will ask for confirmation of security policy
exceptions for each bundled plugin. This commit collects the necessary
permissions of each bundled plugin, and asks for confirmation of all of
them at the same time.
This pull request replaces the jvm-example plugin (from the jvm/site plugins era) by two new plugins: a custom-settings that shows how to register and use custom settings (including secured settings) in a plugin, and rest-handler plugin that shows how to register a rest handler.
The two plugins now reside in the plugins/examples project. They can serve as sample plugins for users, a special attention has been put on documentation. The packaging tests have been adapted to use the custom-settings plugin.
Our rest client throws exceptions in funny ways that might cause
`suppressed` exceptions to be eaten. This works around that in the
reindex-from-old tests so we don't stomp on a real failure. It is fairly
diryt so we should work on fixing the high level rest client.

The current install_plugin() does not play well with meta plugins because
it always checks for the plugin's descriptor file.
This commit changes the install_plugin() so that it only runs the install plugin
command and lets the caller verify that the required files are correctly installed.
It also adds a install_meta_plugin() function to install meta plugins.
Currenty the rest response of the ranking evaluation API wraps all inside an
enclosing `rank_eval` object. This is redundant since it is clear from the API
call and it doesn't provide any other useful information. This change removes
this.
This commit lessens the burden on configuring settings.gradle when new
projects are added. In particular, this makes it trivial to move a
plugin to a module (or vice versa).
This commit modifies the build to require JDK 9 for
compilation. Henceforth, we will compile with a JDK 9 compiler targeting
JDK 8 as the class file format. Optionally, RUNTIME_JAVA_HOME can be set
as the runtime JDK used for running tests. To enable this change, we
separate the meaning of the compiler Java home versus the runtime Java
home. If the runtime Java home is not set (via RUNTIME_JAVA_HOME) then
we fallback to using JAVA_HOME as the runtime Java home. This enables:
- developers only have to set one Java home (JAVA_HOME)
- developers can set an optional Java home (RUNTIME_JAVA_HOME) to test
on the minimum supported runtime
- we can test compiling with JDK 9 running on JDK 8 and compiling with
JDK 9 running on JDK 9 in CI
Currently if the Lucene version is `X.Y.Z-snapshot-{gitrev}`, then we will
expect the docs to have `X.Y.Z-snapshot` as a Lucene version. I would like
to change it to `X.Y.Z` so that this doesn't need changing when we move from a
snapshot to a final release.
This is related to #27933. It introduces a jar named elasticsearch-core
in the lib directory. This commit moves the JarHell class from server to
elasticsearch-core. Additionally, PathUtils and some of Loggers are
moved as JarHell depends on them.
The configuration of the upgraded cluster task was missing a dependency
on the stopping of the second old node in the cluster. In some cases
(e.g., --parallel) Gradle would then try to run the configuration of a
node in the upgraded cluster before it had even configured the old nodes
in the cluster.

This commit adds the ability to package multiple plugins in a single zip.
The zip file for a meta plugin must contains the following structure:
|____elasticsearch/
| |____ <plugin1> <-- The plugin files for plugin1 (the content of the elastisearch directory)
| |____ <plugin2> <-- The plugin files for plugin2
| |____ meta-plugin-descriptor.properties <-- example contents below
The meta plugin properties descriptor is mandatory and must contain the following properties:
description: simple summary of the meta plugin.
name: the meta plugin name
The installation process installs each plugin in a sub-folder inside the meta plugin directory.
The example above would create the following structure in the plugins directory:
|_____ plugins
| |____ <name_of_the_meta_plugin>
| | |____ meta-plugin-descriptor.properties
| | |____ <plugin1>
| | |____ <plugin2>
If the sub plugins contain a config or a bin directory, they are copied in a sub folder inside the meta plugin config/bin directory.
|_____ config
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
|_____ bin
| |____ <name_of_the_meta_plugin>
| | |____ <plugin1>
| | |____ <plugin2>
The sub-plugins are loaded at startup like normal plugins with the same restrictions; they have a separate class loader and a sub-plugin
cannot have the same name than another plugin (or a sub-plugin inside another meta plugin).
It is also not possible to remove a sub-plugin inside a meta plugin, only full removal of the meta plugin is allowed.
Closes#27316
We have a packaging test that tries to install all plugins, and then
asserts that all expected plugins are installed. The expected plugins
are dervied from the list of plugins in the plugins sub-project. The
plugin transport-nio was recently added here, but explicit commands to
install and remove this plugin were never added. This commit addresses
this.
The full-cluster-restart tests are run with two nodes. This can lead to situations where the shrink tests fail because
the replicas are not allocated yet and the shrink operation needs the source shards to be available on the same node.
This is related to #27260. This commit moves the NioTransport from
:test:framework to a new nio-transport plugin. Additionally, supporting
tcp decoding classes are moved to this plugin. Generic byte reading and
writing contexts are moved to the nio library.
Additionally, this commit adds a basic MockNioTransport to
:test:framework that is a TcpTransport implementation for testing that
is driven by nio.
Lucene does not allow adding Lucene 6 files to a Lucene 7 index. This commit ensures that we carry over the Lucene version to the newly created Lucene index.
Closes#28061
This commit adds the infrastructure to plugin building and loading to
allow one plugin to extend another. That is, one plugin may extend
another by the "parent" plugin allowing itself to be extended through
java SPI. When all plugins extending a plugin are finished loading, the
"parent" plugin has a callback (through the ExtensiblePlugin interface)
allowing it to reload SPI.
This commit also adds an example plugin which uses as-yet implemented
extensibility (adding to the painless whitelist).
Previously we disabled these tests on JDK 9 and JDK 10 because Wildfly
10 did not support JDK 9 and JDK 10. With the release of Wildfly 11
supporting JDK 9 and JDK 10 and now that we depend on Wildfly 11 in
these tests, we can enable these tests on JDK 9 and JDK 10.

This commit fixes a flubbed assertion in the Wildfly build file; the
intention was to assert that we have only set the value of the
management port once except the assertion that the management port was
equal to zero when finding a matching log line was left off.
The Wildfly tests previously needed hardcoded ports which would
sometimes already be in use leading to Wildfly test failures because the
server could not bind during startup. We had to wait until some upstream
changes (wildfly/wildfly#9943) and (wildfly/wildfly-core#2390) were
released before we could use ephemeral ports in these tests. These
changes are released now so this commit changes the Wildfly tests to use
ephemeral ports when starting Wildfly.

* Adds task dependenciesInfo to BuildPlugin to generate a CSV file with dependencies information (name,version,url,license)
* Adds `ConcatFilesTask.groovy` to concatenates multiple files into one
* Adds task `:distribution:generateDependenciesReport` to concatenate `dependencies.csv` files into a single file (`es-dependencies.csv` by default)
# Examples:
$ gradle dependenciesInfo :distribution:generateDependenciesReport
## Use `csv` system property to customize the output file path
$ gradle dependenciesInfo :distribution:generateDependenciesReport -Dcsv=/tmp/elasticsearch-dependencies.csv
## When branch is not master, use `build.branch` system property to generate correct licenses URLs
$ gradle dependenciesInfo :distribution:generateDependenciesReport -Dbuild.branch=6.x -Dcsv=/tmp/elasticsearch-dependencies.csv
We disable these tests because the JVM flags we use will not start with
JDK 10. Since we do not support running these old versions on newer JDKs
anyway, this commit disables testing of these when running on JDK 10.
This commit moves GlobalCheckpointTracker from the engine to IndexShard, where it better fits logically: Tracking the global checkpoint based on the local checkpoints of all shards in the replication group is not a property of the engine, but rather a property fulfilled by the current primary shard. The LocalCheckpointTracker on the other hand is driven by the contents of the local translog. By moving GlobalCheckpointTracker to IndexShard, it makes little sense to keep the SequenceNumbersService class around - it would only wrap the LocalCheckpointTracker. This commit therefore removes the class and replaces occurrences of SequenceNumbersService in the engine directly by LocalCheckpointTracker.
