This commit defaults the max local storage nodes to one. The motivation
for this change is that a default value greather than one is dangerous
as users sometimes end up unknowingly starting a second node and start
thinking that they have encountered data loss.

When compiling many dynamically changing scripts, parameterized
scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)
should be preferred. This enforces a limit to the number of scripts that
can be compiled within a minute. A new dynamic setting is added -
`script.max_compilations_per_minute`, which defaults to 15.
If more dynamic scripts are sent, a user will get the following
exception:
```json

This also fixes a bug in `ScriptService` where requests being executed
concurrently on a single node could cause a script to be compiled
multiple times (many in the case of a powerful node with many shards)
due to no synchronization between checking the cache and compiling the
script. There is now synchronization so that a script being compiled
will only be compiled once regardless of the number of concurrent
searches on a node.

This commit fixes a test bug in

that error.
Today when we load the Netty plugins, we indirectly cause several Netty
classes to initialize. This is because we attempt to load some classes
by name, and loading these classes is done in a way that triggers a long
chain of class initializers within Netty. We should not do this, this
can lead to log messages before the logger is loader, and it leads to
initialization in cases when the classes would never be needed (for
example, Netty 3 class initialization is never needed if Netty 4 is
used, and vice versa). This commit avoids this early initialization of
these classes by removing the need for the early loading.

This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.
Closes#19079
This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
* rethrow script compilation exceptions into ingest configuration exceptions
* update readProcessor to rethrow any exception as an ElasticsearchException
Remove `ParseField` constants used for names where there are no deprecated
names and just use the `String` version of the registration method instead.
This is step 2 in cleaning up the plugin interface for extending
search time actions. Aggregations are next.
This is breaking for plugins because those that register a new query should
now implement `SearchPlugin` rather than `onModule(SearchModule)`.
We throw IOException, which is the exception that is going to be thrown in 99% of the cases. A more generic exception can happen, and if it is a runtime one we just let it bubble up as is, otherwise we wrap it into runtime one so that we don't require to catch Exception everywhere, which seems odd.
Also adjusted javadocs for all performRequest methods
The new method accepts the usual parameters (method, endpoint, params, entity and headers) plus a response listener and an async response consumer. Shortcut methods are also added that don't require params, entity and the async response consumer optional.
There are a few relevant api changes as a consequence of the move to async client that affect sync methods:
- Response doesn't implement Closeable anymore, responses don't need to be closed
- performRequest throws Exception rather than just IOException, as that is the the exception that we get from the FutureCallback#failed method in the async http client
- ssl configuration is a bit simpler, one only needs to call setSSLStrategy from a custom HttpClientConfigCallback, that doesn't end up overridng any other default around connection pooling (it used to happen with the sync client and make ssl configuration more complex)

This change removes the multiple ways that plugins can be added to the

Relates #19439
Currently custom headers that should be passed through rest requests are
registered by depending on the RestController in guice and calling a
registration method. This change moves that registration to a getter for
plugins, and makes the RestController take the set of headers on
construction.
Today `node.mode` and `node.local` serve almost the same purpose, they
are a shortcut for `discovery.type` and `transport.type`. If `node.local: true`
or `node.mode: local` is set elasticsearch will start in _local_ mode which means
only nodes within the same JVM are discovered and a non-network based transport
is used. The _local_ mode it only really used in tests or if nodes are embedded.
For both, embedding and tests explicit configuration via `discovery.type` and `transport.type`
should be preferred.
This change removes all the usage of these settings and by-default doesn't
configure a default transport implemenation since netty is now a module. Yet, to make
the user expericence flawless, plugins or modules can set a `http.type.default` and
`transport.type.default`. Plugins set this via `PluginService#additionalSettings()`
which enforces _set-once_ which prevents node startup if set multiple times. This means
that our distributions will just startup with netty transport since it's packaged as a
module unless `transport.type` or `http.transport.type` is explicitly set.
This change also found a bunch of bugs since several NamedWriteables were not registered if a
transport client is used. Now that we don't rely on the `node.mode` leniency which is inherited
instead of using explicit settings, `TransportClient` uses `AssertingLocalTransport` which detects these problems since it serializes all messages.
Closes#16234
This moves all netty related code into modules/transport-netty the module is build as a zip file as well as a JAR to serve as a dependency for transport client. For the time being this is required otherwise we have no network based impl. for transport client users. This might be subject to change given that we move forward http client.
Some tests still start http implicitly or miss configuring the transport clients correctly.
This commit fixes all remaining tests and adds a depdenceny to `transport-netty` from
`qa/smoke-test-http` and `modules/reindex` since they need an http server running on the nodes.
This also moves all required permissions for netty into it's module and out of core.
The callback replaces the ability to fully replace the http client instance. By doing that, one used to lose any default that the RestClient had set for the underlying http client. Given that you'd usually override one or two things only, like a couple of timeout values, the ssl factory or the default credentials providers, it is not uder friendly if by doing that users end up replacing the whole http client instance and lose any default set by us.
This change adds a createComponents() method to Plugin implementations
which they can use to return already constructed componenents/services.
Eventually this should be just services ("components" don't really do
anything), but for now it allows any object so that preconstructed
instances by plugins can still be bound to guice. Over time we should
add basic services as arguments to this method, but for now I have left
it empty so as to not presume what is a necessary service.
this commit moves the most of the http related integ tests out into it's own
`qa/smoke-test-http` project where most of the test can run against the external cluster.

Node IDs are currently randomly generated during node startup. That means they change every time the node is restarted. While this doesn't matter for ES proper, it makes it hard for external services to track nodes. Another, more minor, side effect is that indexing the output of, say, the node stats API results in creating new fields due to node ID being used as keys.
The first approach I considered was to use the node's published address as the base for the id. We already [treat nodes with the same address as the same](https://github.com/elastic/elasticsearch/blob/master/core/src/main/java/org/elasticsearch/discovery/zen/NodeJoinController.java#L387) so this is a simple change (see [here](https://github.com/elastic/elasticsearch/compare/master...bleskes:node_persistent_id_based_on_address)). While this is simple and it works for probably most cases, it is not perfect. For example, if after a node restart, the node is not able to bind to the same port (because it's not yet freed by the OS), it will cause the node to still change identity. Also in environments where the host IP can change due to a host restart, identity will not be the same.
Due to those limitation, I opted to go with a different approach where the node id will be persisted in the node's data folder. This has the upside of connecting the id to the nodes data. It also means that the host can be adapted in any way (replace network cards, attach storage to a new VM). I
It does however also have downsides - we now run the risk of two nodes having the same id, if someone copies clones a data folder from one node to another. To mitigate this I changed the semantics of the protection against multiple nodes with the same address to be stricter - it will now reject the incoming join if a node exists with the same id but a different address. Note that if the existing node doesn't respond to pings (i.e., it's not alive) it will be removed and the new node will be accepted when it tries another join.
Last, and most importantly, this change requires that *all* nodes persist data to disk. This is a change from current behavior where only data & master nodes store local files. This is the main reason for marking this PR as breaking.
Other less important notes:
- DummyTransportAddress is removed as we need a unique network address per node. Use `LocalTransportAddress.buildUnique()` instead.
- I renamed `node.add_lid_to_custom_path` to `node.add_lock_id_to_custom_path` to avoid confusion with the node ID which is now part of the `NodeEnvironment` logic.
- I removed the `version` paramater from `MetaDataStateFormat#write` , it wasn't really used and was just in the way :)
- TribeNodes are special in the sense that they do start multiple sub-nodes (previously known as client nodes). Those sub-nodes do not store local files but derive their ID from the parent node id, so they are generated consistently.
Today throughout the codebase, catch throwable is used with reckless
abandon. This is dangerous because the throwable could be a fatal
virtual machine error resulting from an internal error in the JVM, or an
out of memory error or a stack overflow error that leaves the virtual
machine in an unstable and unpredictable state. This commit removes
catch throwable from the codebase and removes the temptation to use it
by modifying listener APIs to receive instances of Exception instead of
the top-level Throwable.

We have 3 evil tests for jarhell. They have been failing in java 9
because of how evil they are. The first checks the leniency we add for
jarhell in the jdk itself. This is unecessary, since if the leniency
wasn't there, we would already be failing all jarhell checks. The second
is checking the compile version is compatible with the jdk. This is
simpler since we don't need to fake the java version: we know 1.7 should
be compatibile with both java 8 and 9, so we can use that as a constant.
Finally the last test checks if the java version system property is
broken. This is simply something we should not check, we have to trust
that java specifies it correctly, and again, if it was broken, all
jarhell checks would be broken.
Lucene SuppressForbidden is marked lucene.internal and should not be

This commit fixes an issue with the plugins directory being a symbolic
link. Namely, the install plugins command attempts to always create the
plugins directory just in case it does not exist. The JDK method used
here guarantees that the directory is created, and an exception is not
thrown if the directory could not be created because it already
exists. The problem is that this JDK method does not respect symlinks so
its internal existence checks fails, it proceeds to attempt to create
the directory, but the directory creation fails because the symlink
exists. This is documented as being not an issue. We work around this by
checking if there is a symlink where we expect the plugins directory to
be, and only attempt to create if not. We add a unit test that plugin
installation to a symlinked plugins directory works as expected.
This commit removes the ability to specify a custom plugins
path. Instead, the plugins path will always be a subdirectory called
"plugins" off of the home directory.
- now you can specify a list of grok patterns to match your field with

This change makes specifying which boxes to run vagrant tests on a

checkPackagesAllDistros. With this change, there is a single

command line, or in a gradle properties file. There are also two
alias names, 'sample' for a yum and apt box, and 'all' for all boxes.

This commit sets up the default filesystem used during install plugins
tests. A hack is neeeded to handle the temporary directory because the
system property "java.io.tmpdir" will have been initialized to a value
that is sensible for the default filesystem, but not necessarily to a
value that makes sense for the mock filesystem in use during the
tests. This property is restored after each test.
This commit refactors the unit tests for installing plugins to test
against mock filesystems (as well as the native filesystem) for better
test coverage. This commit also adds tests that cover the POSIX
attributes handling when installing plugins (e.g., ensuring that the
plugins directory has the right permissions, the bin directory has
execute permissions, and the config directory has the same owner and
group as its parent).
Today, certain bootstrap properties are set and read via system
properties. This action-at-distance way of managing these properties is
rather confusing, and completely unnecessary. But another problem exists
with setting these as system properties. Namely, these system properties
are interpreted as Elasticsearch settings, not all of which are
registered. This leads to Elasticsearch failing to startup if any of
these special properties are set. Instead, these properties should be
kept as local as possible, and passed around as method parameters where
needed. This eliminates the action-at-distance way of handling these
properties, and eliminates the need to register these non-setting
properties. This commit does exactly that.
Additionally, today we use the "-D" command line flag to set the
properties, but this is confusing because "-D" is a special flag to the
JVM for setting system properties. This creates confusion because some
"-D" properties should be passed via arguments to the JVM (so via
ES_JAVA_OPTS), and some should be passed as arguments to
Elasticsearch. This commit changes the "-D" flag for Elasticsearch
settings to "-E".
This change adds the infrastructure to run the rest tests on a multi-node
cluster that users 2 different minor versions of elasticsearch. It doesn't implement

Since we don't have a real version to test against, the tests uses the current version
until the first minor / RC is released to ensure the infrastructure works.

This commit simplifies and consolidates the two different
implementations of terminals used in tests. There is now a single
MockTerminal which captures output, and allows accessing as one large
string (with unix style \n as newlines), as well as configuring
input.
The big win here is catching tests that are incorrectly named and will
be skipped by gradle, providing a false sense of security.
The whole thing takes about 10 seconds on my Macbook Air, not counting
compiling the test classes, which seems worth it. Because this runs as
a gradle task with propery UP-TO-DATE handling it can be skipped if the
tests haven't been changed which should save some time.
I chose to keep this in test:framework rather than a new subproject of
buildSrc because ESIntegTestCase and doesn't inroduce any additional
dependencies.
DiscoveryService was a bridge into the discovery universe. This is unneeded and we can just access discovery directly or do things in a different way.
One of those different ways, is not having a dedicated discovery implementation for each our dicovery plugins but rather reuse ZenDiscovery.
UnicastHostProviders are now classified by discovery type, removing unneeded checks on plugins.

One of our tests leaked a system property here since we failed after appling some

This commit enableds strict settings validation on node startup. All settings
passed to elasticsearch either through system properties, yaml files or any other
way to pass settings must be registered and valid. Settings that are unknown ie. due to
typos or due to deprecation or removal will cause the node to NOT start up. Plugins
have to declare all their settings on the `SettingsModule#registerSetting` and settings for
plugins that are not installed must be removed.
This commit also removes the ability to specify the nodes name via `-Des.name` or just `name` in the
configuration files. The node name must be prefixed with the node prexif like `node.name: Boom`. Left over
usage of `name` will also cause startup to fail.
Cli tools currently catch all exceptions, and only print the exception
message, except when a special system property is set. Even with this
flag set, certain exceptions, like IOException, are captured and their
stack trace is always lost.
This change adds a UserError class, which can be used a cli tools to
specify a message to the user, as well as an exit status. All other
exceptions are propagated out of main, so java will exit with non-zero
and print the stack trace.
The plugin cli currently is extremely lenient, allowing most errors to
simply be logged. This can lead to either corrupt installations (eg
partially installed plugins), or confused users.
This change rewrites the plugin cli to have almost no leniency.
Unfortunately it was not possible to remove all leniency, due in
particular to how config files are handled.
The following functionality was simplified:
* The format of the name argument to install a plugin is now an official
plugin name, maven coordinates, or a URL.
* Checksum files are required, and only checked, for official plugins
and maven plugins. Checksums are also only SHA1.
* Downloading no longer uses a separate thread, and no longer has a timeout.
* Installation, and removal, attempts to be atomic. This only truly works
when no config or bin files exist.
* config and bin directories are verified before copying is attempted.
* Permissions and user/group are no longer set on config and bin files.
We rely on the users umask.
* config and bin directories must only contain files, no subdirectories.
* The code is reorganized so each command is a separate class. These
classes already existed, but were embedded in the plugin cli class, as
an extra layer between the cli code and the code running for each command.
If we don't do this, and some path.conf is set when starting the tribe node, that path.conf will be ignored and the inner tribe clients will try to read elsewhere, where they most likely don't have permissions to read from.

This commit converts the script mode settings to the new settings
infrastructure. This is a major refactoring of the handling of script
mode settings. This refactoring is necessary because these settings are
determined at runtime based on the registered script engines and the
registered script contexts.
The rest test framework, because it used to be tightly integrated with
ESIntegTestCase, currently expects the addresses for the test cluster to
be passed using the transport protocol port. However, it only uses this
to then find the http address.
This change makes ESRestTestCase extend from ESTestCase instead of
ESIntegTestCase, and changes the sysprop used to tests.rest.cluster,
which now takes the http address.
closes#15459
Site plugins used to be used for things like kibana and marvel, but
there is no longer a need since kibana (and marvel as a kibana plugin)
uses node.js. This change removes site plugins, as well as the flag for
jvm plugins. Now all plugins are jvm plugins.
This creates an reindex plugin with a very basic implementation that is
very like delete-by-query. New we'll integrate it with the task managament
work but for now this works.
Rather than failing the request, when a node with node.ingest set to false receives an index or bulk request with a pipeline id, it should try to redirect the request to another node with node.ingest set to true. If there are no node with ingest set to true based on the current cluster state, an exception will be returned and the request will fail. Note that in case there are no ingest nodes and bulk has a pipeline id specified only for a subset of index requests, the whole bulk will fail.
Now that the ingest infra is part of es core we can remove some code that was required by the plugin and have a better integration with es core. We allow to specify the pipeline id in bulk and index as a request parameter, we have a REST filter that parses it and adds it to the relevant action request. That is not required anymore, as we can add this logic to RestIndexAction and RestBulkAction directly, no need for a filter. Also, we can allow to specify a pipeline id for each index requests in a bulk request. The small downside of this is that the ingest filter has to go over each item of a bulk request, all the time, to figure out whether they have a pipeline id.
CRUD and simulate apis work now fine, every node has the pipelines in memory, but node.ingest disables ingestion, meaning that any index or bulk request with a pipeline id is going to fail
We will keep this abstractions as it's convenient, otherwise IngestDocument would depend on ScriptService directly, and would explicitly rely on mustache which is not even part of core. better to have the interface in core, and the impl as part of the ingest plugin, which relies on mustache, shipped with core by default.
The append processor allows to append one or more values to an existing list; add a new list with the provided values if the field doesn't exist yet, or convert an existing scalar into a list and add the provided values to the newly created list.
This required adapting of IngestDocument#appendFieldValue behaviour, also added support for templating to it.
Closes#14324
This change adds a Fixture class for use by gradle. A Fixture is an
external process that integration tests will use. It can be added as a
dependsOn for integTest, and will automatically be shutdown upon success
or failure, as well as relevant information dumped on failure. There is
also an example fixture in this change.
Added ingest wide template infrastructure to IngestDocument
Added a TemplateService interface that the ingest framework uses
Added a TemplateService implementation that the ingest plugin provides that delegates to the ES' script service
Cut SetProcessor over to use the template infrastructure for the `field` and `value` settings.
Removed the MetaDataProcessor
Removed dependency on mustache library
Added qa ingest mustache rest test so that the ingest and mustache integration can be tested.
This fixes the `lenient` parameter to be `missingClasses`. I will remove this boolean and we can handle them via the normal whitelist.
It also adds a check for sheisty classes (jar hell with the jdk).
This is inspired by the lucene "sheisty" classes check, but it has false positives. This check is more evil, it validates every class file against the extension classloader as a resource, to see if it exists there. If so: jar hell.
This jar hell is a problem for several reasons:
1. causes insanely-hard-to-debug problems (like bugs in forbidden-apis)
2. hides problems (like internal api access)
3. the code you think is executing, is not really executing
4. security permissions are not what you think they are
5. brings in unnecessary dependencies
6. its jar hell
The more difficult problems are stuff like jython, where these classes are simply 'uberjared' directly in, so you cant just fix them by removing a bogus dependency. And there is a legit reason for them to do that, they want to support java 1.4.
This change removes hardcoded ports from cluster formation. It passes
port 0 for http and transport, and then uses a special property to have
the node log the ports used for http and transport (just for tests).
This does not yet work for multi node tests. This brings us one step
closer to working with --parallel.
This commit removes and now forbids all uses of
Collections#shuffle(List) and Random#<init>() across the codebase. The
rationale for removing and forbidding these methods is to increase test
reproducibility. As these methods use non-reproducible seeds, production
code and tests that rely on these methods contribute to
non-reproducbility of tests.
Instead of Collections#shuffle(List) the method
Collections#shuffle(List, Random) can be used. All that is required then
is a reproducible source of randomness. Consequently, the utility class
Randomness has been added to assist in creating reproducible sources of
randomness.
Instead of Random#<init>(), Random#<init>(long) with a reproducible seed
or the aforementioned Randomess class can be used.
Closes#15287
The NodeBuilder is currently used to construct a Node. However, this is
really just yet-another-builder that wraps around a Settings.Builder
witha couple convenience methods. But there are very few uses of these
convenience methods. This change removes NodeBuilder, in favor of just
using the Node constructor.
The tribe node creates one local client node for each cluster it
connects to. Refactorings in #13383 broke this so that each local client
node now tries to load the full elasticsearch.yml that the real tribe
node uses.
This change fixes the problem by adding a TribeClientNode which is a
subclass of Node. The Environment the node uses is now passed in (in
place of Settings), and the TribeClientNode simply does not use
InternalSettingsPreparer.prepareEnvironment.
The tests around tribe nodes are not great. The existing tests pass, but
I also manually tested by creating 2 local clusters, and configuring and
starting a tribe node. With this I was able to see in the logs the tribe
node connecting to each cluster.
closes#13383
We currently use the full suite of packaged rest tests for each
distribution. We also used to run rest tests within core integ tests,
but this stopped working when we split out the test-framework, since the
test files are in there.
This change simplifies the code to run packaged rest tests just once,
for the integ-test-zip, and removes the unused rest tests from
test-framework. Distributions rest tests now check that all modules
were loaded.
The current mechanism for adding plugins to the integTest cluster is to
have a FileCollection. This works well for the integTests for a single
plugin, which automatically adds itself to be installed. However, for qa
tests where many plugins may be installed, and from other projects, it
is cumbersome to add configurations, dependencies and dependsOn
statements over and over. This simplifies installing a plugin from
another project by moving this common setup into the cluster
configuration code.
This change adds back the multi node smoke test, as well as making the
cluster formation for any test allow multiple nodes. The main changes in
cluster formation are abstracting out the node specific configuration to
a helper struct, as well as making a single wait task that waits for all
nodes after their start tasks have run. The output on failure was also
improved to log which node's info is being printed.
Currently we use the "gradle project attachment plugin" to support
building elasticsearch as part of another project. However, this plugin
has a number of issues, a large part of which is requiring consistent
use of the projectsPrefix.
This change removes projectsPrefix, and adds support for a special
extra-plugins directory in the root of elasticsearch. Any projects
checked out within this directory will be automatically added to
elasticsearch.
* Forbid System.setProperties & co in forbidden APIs.
* Ban property write access at runtime with security manager.
Plugins that need to modify system properties will need to request permission in their plugin-security.policy

It does not make the "check" task depend on "checkPackages" so running the
vagrant tests is still optional. They are slow and depend on vagrant and
virtualbox.
The Package Verification tasks are useful for testing individual distros.
The Vagrant tasks are listed in `gradle tasks` primarily for discoverability.
This change removes the leftover pom files. A couple files were left for
reference, namely in qa tests that have not yet been migrated (vagrant
and multinode). The deb and rpm assemblies also still exist for
reference when finishing their setup in gradle.
See #13930
There are three ways `@Test` was used. Way one:
```java
@Test
public void flubTheBlort() {
```
This way was always replaced with:
```java
public void testFlubTheBlort() {
```
Or, maybe with a better method name if I was feeling generous.
Way two:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
methodThatThrows();
}
```
This way of using `@Test` is actually pretty OK, but to get the tools to ban
`@Test` entirely it can't be used. Instead:
```java
public void testFoo() {
try {
methodThatThrows();
fail("Expected IllegalArgumentException");
} catch (IllegalArgumentException e ) {
assertThat(e.getMessage(), containsString("something"));
}
}
```
This is longer but tests more than the old ways and is much more precise.
Compare:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
some();
copy();
and();
pasted();
methodThatThrows();
code(); // <---- This was left here by mistake and is never called
}
```
to:
```java
@Test(throws=IllegalArgumentException.class)
public void testFoo() {
some();
copy();
and();
pasted();
try {
methodThatThrows();
fail("Expected IllegalArgumentException");
} catch (IllegalArgumentException e ) {
assertThat(e.getMessage(), containsString("something"));
}
}
```
The final use of test is:
```java
@Test(timeout=1000)
public void testFoo() {
methodThatWasSlow();
}
```
This is the most insidious use of `@Test` because its tempting but tragically
flawed. Its flaws are:
1. Hard and fast timeouts can look like they are asserting that something is
faster and even do an ok job of it when you compare the timings on the same
machine but as soon as you take them to another machine they start to be
invalid. On a slow VM both the new and old methods fail. On a super-fast
machine the slower and faster ways succeed.
2. Tests often contain slow `assert` calls so the performance of tests isn't
sure to predict the performance of non-test code.
3. These timeouts are rude to debuggers because the test just drops out from
under it after the timeout.
Confusingly, timeouts are useful in tests because it'd be rude for a broken
test to cause CI to abort the whole build after it hits a global timeout. But
those timeouts should be very very long "backstop" timeouts and aren't useful
assertions about speed.
For all its flaws `@Test(timeout=1000)` doesn't have a good replacement __in__
__tests__. Nightly benchmarks like http://benchmarks.elasticsearch.org/ are
useful here because they run on the same machine but they aren't quick to check
and it takes lots of time to figure out the regressions. Sometimes its useful
to compare dueling implementations but that requires keeping both
implementations around. All and all we don't have a satisfactory answer to the
question "what do you replace `@Test(timeout=1000)`" with. So we handle each
occurrence on a case by case basis.
For files with `@Test` this also:
1. Removes excess blank lines. They don't help anything.
2. Removes underscores from method names. Those would fail any code style
checks we ever care to run and don't add to readability. Since I did this manually
I didn't do it consistently.
3. Make sure all test method names start with `test`. Some used to end in `Test` or start
with `verify` or `check` and they were picked up using the annotation. Without the
annotation they always need to start with `test`.
4. Organizes imports using the rules we generate for Eclipse. For the most part
this just removes `*` imports which is a win all on its own. It was "required"
to quickly remove `@Test`.
5. Removes unneeded casts. This is just a setting I have enabled in Eclipse and
forgot to turn off before I did this work. It probably isn't hurting anything.
6. Removes trailing whitespace. Again, another Eclipse setting I forgot to turn
off that doesn't hurt anything. Hopefully.
7. Swaps some tests override superclass tests to make them empty with
`assumeTrue` so that the reasoning for the skips is logged in the test run and
it doesn't "look like" that thing is being tested when it isn't.
8. Adds an oxford comma to an error message.
The total test count doesn't change. I know. I counted.
```bash
git checkout master && mvn clean && mvn install | tee with_test
git no_test_annotation master && mvn clean && mvn install | tee not_test
grep 'Tests summary' with_test > with_test_summary
grep 'Tests summary' not_test > not_test_summary
diff with_test_summary not_test_summary
```
These differ somewhat because some tests are skipped based on the random seed.
The total shouldn't differ. But it does!
```
1c1
< [INFO] Tests summary: 564 suites (1 ignored), 3171 tests, 31 ignored (31 assumptions)
---
> [INFO] Tests summary: 564 suites (1 ignored), 3167 tests, 17 ignored (17 assumptions)
```
These are the core unit tests. So we dig further:
```bash
cat with_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > with_test_suites
cat not_test | perl -pe 's/\n// if /^Suite/;s/.*\n// if /IGNOR/;s/.*\n// if /Assumption #/;s/.*\n// if /HEARTBEAT/;s/Completed .+?,//' | grep Suite > not_test_suites
diff <(sort with_test_suites) <(sort not_test_suites)
```
The four tests with lower test numbers are all extend `AbstractQueryTestCase`
and all have a method that looks like this:
```java
@Override
public void testToQuery() throws IOException {
assumeTrue("test runs only when at least a type is registered", getCurrentTypes().length > 0);
super.testToQuery();
}
```
It looks like this method was being double counted on master and isn't anymore.
Closes#14028
This commit makes sure that the plugin script looks at user, group and permissions of the elasticsearch bin dir and copies them over to the plugin bin subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed. We also make sure that execute permissions are added for files (we already did this before).
Relates to #11016Closes#14088
Depending on how elasticsearch is installed, we have two scenarios to take into account that relate to user, group and permissions assigned to the config directory:
1) deb/rpm package: /etc/elasticsearch is root:elasticsearch 750 and the plugin script is run from root user
2) tar/zip archive: es config dir is most likely elasticsearch:elasticsearch and the plugin script is most likely run from elasticsearch user
When the plugin script copies over the plugin config dir within the es config dir, it should take care of setting the proper user, group and permissions, which vary depending on how elasticsearch was installed in the first place. Should be root:elasticsearch 750 if installed from a package, or elasticsearch:elasticsearch if installed from an archive.
This commit makes sure that the plugin script looks at user, group and permissions of the config dir and copies them over to the plugin config subdirectory, whatever they are, so that they get properly setup depending on how elasticsearch was installed in the first place. We also make sure that execute permissions are left untouched for files.
Relates to #11016Closes#14048
When generating the rpm and dep package we now set proper group (elasticsearch) and permissions (750) to the conf dir (default /etc/elasticsearch). Same for the scripts subdirectory.
Expanded the assert_file bash function to also optionally check the group of files, so we can actually test that the group was set correctly.

package installation creates the plugin directory already so when a plugin
is installed it prints the additional line
Plugins directory [/tmp/elasticsearch/plugins] does not exist. Creating...
Plugin cli tools configures logging with whatever is in the logging.yml.
If a file appender is configured for any of the logs this will cause creation
of an empty log file. If a plugin was for example installed as root it will
create empty logs at es.home/logs.
This is problematic when for example plugins are installed as root and es is run
as service. Logs will then be created in /usr/share/elasticsearch/logs
and can later not be removed by for example dpkg -r or -purge.
To avoid this, configure the logger to use an appender that writes to the same
output that plugin cli tool does. This allows other components that are called
from Plugin cli tool to write to the same terminal that plugin cli tool writes to
by using the logging mechanism already in place.
The logging conf is not read at all pb plugin cli tool.
As a side effect, the loging level for components that are called
from the plugin command such as the jar hell check can now be configured
with -Des.logger.level which makes it easier to debug the jar hell check.
Installs javatana in vivid, emulates its on-login actions when starting
elasticsearch and verifies that elasticsearch turns off javatana.
Relates to #13813
Before this commit he tests always run bin/plugin as root which is somewhat
unrealistic and causes trouble (log files owned by root instead of
elasticsearch). After this commit `bin/plugin` runs as root when elasticsearch
is installed via the repository and as elasticsearch otherwise which is much
more realistic.
This also adds extra timeout to starting elasticsearch which is required
when all the plugins are installed. And it fixes up a problem with logging
elasticsearch's log if elasticsearch doesn't start which came up multiple
time while debugging this problem.
Also adds docs recommending running `bin/plugin` as the user that owns the
Elasticsearch files or root if installed with the packages.

This adds SuSe Linux Enterprise Server 12 to the list of tested VMs.
SLES 12 is using systemd, so that the current RPM works

SLES12 however is already quite old and does not ship with java8, so this
required adding an opensuse repo.
Fix the vagrant tests after azure was split into 3 plugins. The tests
need to list all the plugins and some dependency so we can make sure the
plugin can be installed and uninstalled.
Until now we had a cloud-azure plugin which is providing 3 distinct features:
* discovery on Azure
* snapshot/restore on Aure
* SMB store
This commit splits the plugin by feature so people can use either one or the other or both features.
Doc is updated accordingly.
Right now we execute some debian-isms in the init.d tests. This switches to
trying both the debian and centos ways to stop services from starting
automatically.
The AWS plugin was broken into discovery-ec2 and repository-s3 so we can't
test the old plugin and must test the new ones.
Fixed some wording issues in test names.
This changes the packaging tests to start Elasticsearch with all plugins
installed and checks `_cat/plugins?h=c` against the list of plugins in
the plugins directory. If the list differs, error! So it proves that the
plugins can be installed using bin/plugin as shipped in the rpm and deb
packages.
Closes#13254
There are two other obvious ways to implement the "packages don't start
elasticsearch" checks but when you work through them they aren't as nice
as the implementation of the checks that we use now. This just adds
documentation to that effect.
We don't want either the deb or rpm package to start elasticsearch as soon
as they install nor do we want the package to register elasticsearch to
start on restart. That action is reserved for the administrator. This adds
tests for that.
Closes#13122
To do this we:
1. All the rpm based distros we test support Java 8. We just ask to install
it.
2. There is a ppa that works for the Ubuntus. We just add that for them.
3. Debian Jessie has Java 8 in its backports. We just add that repository.
4. Debian Wheezy doesn't have Java 8 easily accessible so we drop it. We
could add it back with Orache Java 8 at a later date but that will take a
few more backflips and won't support things like vagrant-cachier.
This required a ton of rebuilding of vagrant boxes so it also fixes:
1. apt-get update is run too frequently
2. Lots of weird warning messages are spit out of apt-get
3. Switch from the chef provided based images to those provided by boxcutter.
The chef images has left vagrant atlas!
Closes#13366

This commit adds a new smoke test for testing client as a end Java user.
It starts a cluster in `pre-integration-test` phase, then execute the client operations defined as JUnit tests within `integration-test` phase and then stop the external cluster in `post-integration-test` phase.
You can also run test classes from your IDE.
* Start an external node on your machine with `bin/elasticsearch` (note that you can test Java API regressions if you run an older or newer node version)
* Run the JUnit test. By default, it will run tests on `localhost:9300` but you can change this setting using system property `tests.cluster`. It also expects the default `cluster.name` (`elasticsearch`).
This commit also starts adding [snippets as defined by Maven](https://maven.apache.org/guides/mini/guide-snippet-macro.html) to help keeping automatically synchronized the Java reference guide with the current code.
Our documentation builder tool does not support snippets though but we will most likely support it at some point.
The shaded version of elasticsearch was built at the very beginning to avoid dependency conflicts in a specific case where:
* People use elasticsearch from Java
* People needs to embed elasticsearch jar within their own application (as it's today the only way to get a `TransportClient`)
* People also embed in their application another (most of the time older) version of dependency we are using for elasticsearch, such as: Guava, Joda, Jackson...
This conflict issue can be solved within the projects themselves by either upgrade the dependency version and use the one provided by elasticsearch or by shading elasticsearch project and relocating some conflicting packages.
Example
-------
As an example, let's say you want to use within your project `Joda 2.1` but elasticsearch `2.0.0-beta1` provides `Joda 2.8`.
Let's say you also want to run all that with shield plugin.
Create a new maven project or module with:
```xml
<groupId>fr.pilato.elasticsearch.test</groupId>
<artifactId>es-shaded</artifactId>
<version>1.0-SNAPSHOT</version>
<properties>
<elasticsearch.version>2.0.0-beta1</elasticsearch.version>
</properties>
<dependencies>
<dependency>
<groupId>org.elasticsearch</groupId>
<artifactId>elasticsearch</artifactId>
<version>${elasticsearch.version}</version>
</dependency>
<dependency>
<groupId>org.elasticsearch.plugin</groupId>
<artifactId>shield</artifactId>
<version>${elasticsearch.version}</version>
</dependency>
</dependencies>
```
And now shade and relocate all packages which conflicts with your own application:
```xml
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>2.4.1</version>
<executions>
<execution>
<phase>package</phase>
<goals>
<goal>shade</goal>
</goals>
<configuration>
<relocations>
<relocation>
<pattern>org.joda</pattern>
<shadedPattern>fr.pilato.thirdparty.joda</shadedPattern>
</relocation>
</relocations>
</configuration>
</execution>
</executions>
</plugin>
</plugins>
</build>
```
You can create now a shaded version of elasticsearch + shield by running `mvn clean install`.
In your project, you can now depend on:
```xml
<dependency>
<groupId>fr.pilato.elasticsearch.test</groupId>
<artifactId>es-shaded</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>joda-time</groupId>
<artifactId>joda-time</artifactId>
<version>2.1</version>
</dependency>
```
Build then your TransportClient as usual:
```java
TransportClient client = TransportClient.builder()
.settings(Settings.builder()
.put("path.home", ".")
.put("shield.user", "username:password")
.put("plugin.types", "org.elasticsearch.shield.ShieldPlugin")
)
.build();
client.addTransportAddress(new InetSocketTransportAddress(new InetSocketAddress("localhost", 9300)));
// Index some data
client.prepareIndex("test", "doc", "1").setSource("foo", "bar").setRefresh(true).get();
SearchResponse searchResponse = client.prepareSearch("test").get();
```
If you want to use your own version of Joda, then import for example `org.joda.time.DateTime`. If you want to access to the shaded version (not recommended though), import `fr.pilato.thirdparty.joda.time.DateTime`.
You can run a simple test to make sure that both classes can live together within the same JVM:
```java
CodeSource codeSource = new org.joda.time.DateTime().getClass().getProtectionDomain().getCodeSource();
System.out.println("unshaded = " + codeSource);
codeSource = new fr.pilato.thirdparty.joda.time.DateTime().getClass().getProtectionDomain().getCodeSource();
System.out.println("shaded = " + codeSource);
```
It will print:
```
unshaded = (file:/path/to/joda-time-2.1.jar <no signer certificates>)
shaded = (file:/path/to/es-shaded-1.0-SNAPSHOT.jar <no signer certificates>)
```
This PR also removes fully-loaded module.
By the way, the project can now build with Maven 3.3.3 so we can relax a bit our maven policy.
This cleans up deb, rpm, systemd, and sysvinit tests:
1. Move skip_not_rpm, skip_not_dpkg, etc to the setup() methods for faster
runtime and cleaner code.
2. Removed lots of needless invocations of `run`
3. Created install_package for use in the systemd and sysvinit tests.
4. Removed lots of needless stderr to stdout redirects.
Closes#13075
Related to #13074
Virtualbox is the default virtualization provier for vagrant but folks
override that from time to time. If they do then the build will fail because
the boxes used by the build don't usually support non-virtualbox providers.
Closes#13217
commons-lang really is only used by some core classes to join strings or modiy arrays.
It's not worth carrying the dependency. This commit removes the dependency on commons-lang
entirely.
Now we are using short names for artifactId (see #12879) so we don't need anymore to transform long names `elasticsearch-pluginname` to short names `pluginname` in ant script when we install a plugin.
Modify also convert-plugin-name
Clean up remaining plugins with old format
And fix vagrant tests
In #12853 we actually introduced a test regression. Now as we wait for yellow instead of green, we might have some pending tasks.
This commit simplify all that and only checks the number of nodes within the cluster.
In plugins, we are using non consistent naming. We use `elasticsearch-cloud-aws` as the artifactId, which generates a jar file called `elasticsearch-cloud-aws-VERSION.jar`.
But when you want to install the plugin, you will end up with a shorter name for the plugin `cloud-aws`.
```
bin/plugin install cloud-aws
```
This commit changes that and use consistent names for `artifactId`, so `finalName`.
Also changed maven names.
Indeed, we check within the test suite that we have not unassigned shards.
But when the test starts on my machine I get:
```
[elasticsearch] [2015-08-13 12:03:18,801][INFO ][org.elasticsearch.cluster.routing.allocation.decider] [Kehl of Tauran] low disk watermark [85%] exceeded on [eLujVjWAQ8OHdhscmaf0AQ][Jackhammer] free: 59.8gb[12.8%], replicas will not be assigned to this node

We don't check anymore if we have unassigned shards and we wait for `yellow` status instead of `green`.
Closes#12852.
This move the `murmur3` field to the `mapper-murmur3` plugin and fixes its
defaults so that values will not be indexed by default, as the only purpose
of this field is to speed up `cardinality` aggregations on high-cardinality
string fields, which only requires doc values.
I also removed the `rehash` option from the `cardinality` aggregation as it
doesn't bring much value (rehashing is cheap) and allowed to remove the
coupling between the `cardinality` aggregation and the `murmur3` field.
Close#12874
1. Move `clean_before_test` to the first test so its more explicit.
2. Move `skip_not_tar_gz` to setup because it was run first in every test.
3. Remove calls to `run` that only check the status. Its simpler to just
execute the command. Its better because std-out will be captured and replayed
on error.
4. Switch from `su` to `sudo` because `su` was breaking `bats`'s error
reporting.
In the bats test ES_CLEAN_BEFORE_TEST was used to clean the environment
before running the tests. Unfortunately the tests don't work unless you
specify it every time. This removes that option and always runs the clean.
Build fails with maven 3.3.1 and 3.3.3. To reproduce, install one of the 3.3.x versions of maven and run `mvn clean verify` in the root directory of the project. The build will fail in the QA: Smoke Test Shaded Jar module with the following error:

Please note that build doesn't fail with maven 3.2.x and it doesn't fail if mvn command is executed inside the qa/smoke-test-shaded directory. Only when the build is started from the root directory the error above can be observed.
The reason is because of the shaded version which depends on elasticsearch core.
When Maven build the module only, then elasticsearch core is not added to the dependency tree.
```sh
mvn dependency:tree -pl :smoke-test-shaded
```
```

A fix could consist of fixing something on Maven side. Probably something changed in a recent version and introduced this "issue" but it might be not really an issue. More a fix.
There are two workarounds:
1) exclude manually elasticsearch core from shaded version in smoke-test-shaded module and add manually each lucene lib needed by elasticsearch
2) add a new `elasticsearch-lucene` (lucene) POM module which simply declares all needed lucene libs in subprojects (such as the smoke tester one).
I choose the later.
Closes#12791.
This adds the infrastrucutre to run integration tests with more than one node.
* it adds relevant macros and targets to integration-tests.xml to start unicast nodes
* there is a qa/smoke-test-multinode project that simulates such a setup
this commit is soely the infrastructure and doesn't hook up any projects to use this.
For reliability and stability reasons this should be used with care and only if it's really
needed.
Closes#12718
the default classloader. It had all kinds of leniency in how the
classname was found, and simply cannot work with plugins having isolated
classloaders.
This change removes that method. Some of the uses of it were for custom
extension points, like custom repository or discovery types. A lot were
just there to plugin mock implementations for tests. For the settings
that were legitimate, all now support plugins adding the given setting
via onModule. For those that were specific to tests for mocks, they now
use Classes.loadClass (a helper around Class.forName). This is a
temporary measure until (in a future PR) tests can change the
implementation via package private statics.
I also removed a number of unnecessary intermediate modules, added a
"jvm-example" plugin that can be filled in in the future as a smoke test
for breaking plugins, and gave some documentation to "spawn" modules
interface.

If we run the tests as a reactor build we reference the dependencies
before they are shaded. This causes problems since we verify that unshaded versions
of a transitive dependency is not present. This commit moves the verification tests
into the integration test that always runs with the shaded version of the jar.
This creates a module in qa called vagrant that can be run if you have
vagrant and virtualbox installed and will run the packaging tests in trusty
and centos-7.0. You can ask it to run tests in other linuxes. This is the full
list:
* precise aka Ubuntu 12.04
* trusty aka Ubuntu 14.04
* vivid aka Ubuntun 15.04
* wheezy aka Debian 7, the current debian oldstable distribution
* jessie aka Debian 8, the current debina stable distribution
* centos-6
* centos-7
* fedora-22
* oel-7
There is lots of documentation on how to do this in the TESTING.asciidoc.
Closes#12611
Moved the license checker config into the parent pom, and overrede
the license dir/target-to-check in distributions/pom.
Disabled the license checker explicitly for projects which run integration
tests but have no licenses dir:
* core
* distribution
* qa
* plugins/delete-by-query
* plugins/mapper-size
* plugins/site-example
Closes#12752Closes#12754
this commit adds a simple integration test that starts a
node from a shaded jar, indexes a doc and retrieves it. It
also has some basic unittests that try to load shaded classes and ensure
that their counterpart is not in the classpath.
Closes#12711
This is one of our esoteric metadata mappers so I think we should distribute
it in a plugin rather than in elasticsearch core.
This introduces one limitation: the value of the `_size` parameter is not
retrievable for documents that are only in the transaction log.
We have a smoke_test_plugins.py, but its a bit slow, not integrated
into our build, etc.
I converted this into an integration test. It is definitely uglier
but more robust and fast (e.g. 20 seconds time to verify).
Also there is refactoring of existing integ tests logic, like printing
out commands we execute and stuff
