internal cluster communication.
See CorruptedCompressorTests for details on how this bug can be hit.
This change also removes the ability to use the unsafe variant of
ChunkedEncoder, removing support for the compress.lzf.decoder setting.
CliTool is a base class for command-line interface tools (such as the plugin manager and potentially others). It supports the following:
- single or multi command tool
- help printing infrastructure (based on help files)
- consistent mechanism of parsing arguments (based on commons-cli lib)
- separation of argument parsing and command execution (for easier unit testing)
- terminal abstraction (will use System.console() when available)
This commit adds a profile that skips all validation ie.
- nocommit / tabs checking
- forbidden API checks
- license headers
It's not active by default but can easily be activated with
`mvn -Pdev` or in the `~/.m2/settings.xml`
for reference see:

We parse the version that is shipped with the Lucene segments in order
to find the version of lucene that wrote a particular segment. Yet, some lucene
version ie:
* 4.3.1 (Elasticsearch 0.90.2)
* 4.5.1 (Elasticsearch 0.90.7)
* 3.6.1 (pre Elasticsearch 0.90.0)
wrote illegal strings containing the minor version which causes IAE exceptions
being thrown from lucenes parsing method.
Closes#7055
These are javascript expressions, which can only access numeric
fielddata, parameters, and _score. They can only be used for searches (not document updates).
closes#6818
In order to have access to all codecs and handlers by netty, they
need to be exposed during shading, otherwise only the classes, which
are used by the built are exposed.
`-Dtests.filter` allows to pass filter expressions to the elasticsearch
tests. This allows to filter test annotaged with TestGroup annotations
like @Slow, @Nightly, @Backwards, @Integration with a boolean expresssion like:
* to run only backwards tests run:
`mvn -Dtests.bwc.version=X.Y.Z -Dtests.filter="@backwards"`
* to run all integration tests but skip slow tests run:
`mvn -Dtests.filter="@integration and not @slow"
* to take defaults into account ie run all test as well as backwards:
`mvn -Dtests.filter="default and @backwards"
This feature is a more powerful alternative to flags like
`-Dtests.nighly=true|false` etc.
Closes#6703
Some IO api can return after writing & reading only a part of the requested data. On these rare occasions, we should call the methods again to read/write the rest of the data. This has cause rare translog corruption while writing huge documents on Windows.
Noteful parts of the commit:
- A new Channels class with utility methods for reading and writing to channels
- Writing or reading to channels is added to the forbidden API list
- Added locking to SimpleFsTranslogFile
- Removed FileChannelInputStream which was not used
Closes#6441 , #6576
Sandboxes the groovy scripting language with multiple configurable
whitelists:
`script.groovy.sandbox.receiver_whitelist`: comma-separated list of string
classes for objects that may have methods invoked.
`script.groovy.sandbox.package_whitelist`: comma-separated list of
packages under which new objects may be constructed.
`script.groovy.sandbox.class_whitelist` comma-separated list of classes
that are allowed to be constructed.
As well as a method blacklist:
`script.groovy.sandbox.method_blacklist`: comma-separated list of
methods that are never allowed to be invoked, regardless of target
object.
The sandbox can be entirely disabled by setting:
`script.groovy.sandbox.enabled: false`
This commit add a basic infrastructure as well as primitive tests
to ensure version backwards compatibility between the current
development trunk and an arbitrary previous version. The compatibility
tests are simple unit tests derived from a base class that starts
and manages nodes from a provided elasticsearch release package.
Use the following commandline executes all backwards compatiblity tests
in isolation:
```
mvn test -Dtests.bwc=true -Dtests.bwc.version=1.2.1 -Dtests.class=org.elasticsearch.bwcompat.*
```
These tests run basic checks like rolling upgrades and
routing/searching/get etc. against the specified version. The version
must be present in the `./backwards` folder as
`./backwards/elasticsearch-x.y.z`
This commit adds checks for nocommit and tabs in the source code.
The task is executed during the validate phase and can be disabled via
`-Dvalidate.skip`
E.g. we use Unsafe in quite a few places and this generates lots of
warnings, which we now suppress using the undocumented
-XDignore.symbol.file command-line option to javac.
Closes#6423
Routing has been inadvertly changed in #5562 resulting in documents going to
different shards in 1.2. This is a terrible bug because an indexing request
would not necessarily go to the same shard anymore, potentially leading to
duplicates.
Close#6391
This commit upgrades to the latest Lucene 4.8.1 release including the
following bugfixes:
* An IndexThrottle now kicks in when merges start falling behind
limiting index threads to 1 until merges caught up. Closes#6066
* RateLimiter now kicks in at the configured rate where previously
the limiter was limiting at ~8MB/sec almost all the time. Closes#6018
* If plugin does not provide `lucene` property, we consider that the plugin is compatible.
* If plugin provides `lucene` property, we try to load related Enum org.apache.lucene.util.Version. If this fails, it means that the node is too "old" comparing to the Lucene version the plugin was built for.
* We compare then two first digits of current node lucene version against two first digits of plugin Lucene version. If not equal, it means that the plugin is too "old" for the current node.
Plugin developers who wants to launch plugin check only have to add a `lucene` property in `es-plugin.properties` file. If you are using maven to build your plugin, you can do it like this:
In `pom.xml`:
```xml
<properties>
<lucene.version>4.6.0</lucene.version>
</properties>
<build>
<resources>
<resource>
<directory>src/main/resources</directory>
<filtering>true</filtering>
</resource>
</resources>
</build>
```
In `es-plugin.properties`, add:
```properties
lucene=${lucene.version}
```
BTW, if you don't already have it, you can add the plugin version as well:
```properties
version=${project.version}
```
You can disable that check using `plugins.check_lucene: false`.
We configure the threadpools according to the number of processors which is
different on every machine. Yet, we had some test failures related to this
and #6174 that only happened reproducibly on a node with 1 available processor.
This commit does:
* sometimes randomize the number of available processors
* if we don't randomize we should set the actual number of available processors
in the settings on the test node
* always print out the num of processors when a test fails to make sure we can
reproduce the thread pool settings with the reproduce info line
Closes#6176
Our improvements to t-digest have been pushed upstream and t-digest also got
some additional nice improvements around memory usage and speedups of quantile
estimation. So it makes sense to use it as a dependency now.
This also allows to remove the test dependency on Apache Mahout.
Close#6142
Updating to this version allows to configure a special JNA directory,
in case the /tmp directory is mounted with the noexec option, as JNA
extracts some data and tries to execute parts of it.
Also updated documentation to clarify mlockall and memory settings as well
as pointing to the new jna.tmpdir system property.
Closes#5493
Needed for REST backwards compatibility tests, since we need to run older tests with the latest runner, which randomizes shards and replicas, but the tests rely on defaults (5,1).
Done in a generic way based on compatibility versions e.g. `-Dtests.compatibility=1.0.0` allows to run tests in a special manner that is compatibile with 1.0.0 version.
Also moved back randomIndexTemplate to ElasticsearchIntegrationTest (from ImmutableCluster) where all the randomized aspects should be.
Closes#5897
The blacklist can be provided through -Dtests.rest.blacklist and supports a comma separated list of globs
e.g. -Dtests.rest.blacklist=get/10_basic/*,index/*/*
Also added some missing docs and made it clearer that the suite/test descriptions effectively contains their (relative) path (api/yaml_file/test section)
Closes#5881
