We have a "HUGE HACK" that allows us to publish zip artifacts to
Sonatype's OSS repository without javadoc and source jars. We don't
include those jars because the zip is just a repackaging of the
core and module jars for which we already publish the javadoc and
source jars. So we have a hack to publish the zip artifact when the
pom says the project is of type 'pom'.
The build currently depends on the presence of a Git remote named origin to determine the URL that is used in the generated POM file. As this is best-effort anyhow and only required by Maven Central, this commit allows the build to run even if a Git remote with the name "origin" is missing.
With the switch to Log4j 2 throughout our code base, the logger usage checker was temporarily disabled. This commit
adapts the checks to work with Log4j 2 and re-enables the Gradle checks.

I'm not sure why we need this pom instead of the pom generated by
nebula, but if we are going to have it then we need to populate it
with appropriate stuff like project name, description, and url.
Gradle appears to have a bug in maven publshing which will not match the
artifactId of a generated pom with the artifact id it puts in the file.
This adds back a copy hack from the original pom file name to the client
pom file name (which we had before #20403 inadvertently
removed it).
This commit adds a new test TribeIT#testClusterStateNodes() to verify that the tribe node correctly reflects the nodes of the remote clusters it is connected to.
It also changes the existing tests so that they really use two remote clusters now.
* Build: Remove old maven deploy support
This change removes the old maven deploy that we have in parallel to
maven-publish, and makes maven-publish fully work with publishing to
maven local. Using `gradle publishToMavenLocal` should be used to
publish to .m2.
Note that there is an unfortunate hack that means for
zip artifacts we must first create/publish a dummy pom file, and then
follow that with the real pom file. It would be nice to have the pom
file contains packaging=zip, but maven central then requires sources and
javadocs. But our zips are really just attached artifacts, so we already
set the packaging type to pom for our zip files. This change just works
around a limitation of the underlying maven publishing library which
silently skips attached artifacts when the packaging type is set to pom.

* Remove unnecessary extra spacing
We were using maven snapshots during heavy development, but this should

This tracks the snippets that probably should be converted to
`// CONSOLE` or `// TESTRESPONSE` and fails the build if the list
of files with such snippets doesn't match the list in `docs/build.gradle`.
Setting the file looks like
```
/* List of files that have snippets that probably should be converted to
* `// CONSOLE` and `// TESTRESPONSE` but have yet to be converted. Try and
* only remove entries from this list. When it is empty we'll remove it

This list is in `build.gradle` because we expect it to be fairly
temporary. In a few months we'll have converted all of the docs and won't
ned it any more.
From now on if you add now docs that contain a snippet that shows an
interaction with elasticsearch you have three choices:
1. Stick `// CONSOLE` on the interactions and `// TESTRESPONSE` on the
responses. The build (specifically (`gradle docs:check`) will test that
these interactions "work". If there isn't a `// TESTRESPONSE` snippet
then "work" just means "Elasticsearch responds with a 200-level response
code and no `WARNING` headers. This is way better than nothing.
2. Add `// NOTCONSOLE` if the snippet isn't actually interacting with
Elasticsearch. This should only be required for stuff like javascript
source code or `curl` against an external service like AWS or GCE. The
snippet will not get "OPEN IN CONSOLE" or "COPY AS CURL" buttons or be
tested.
3. Add `// TEST[skip:reason]` under the snippet. This will just skip the
snippet in the test phase. This should really be reserved for snippets
where we can't test them because they require an external service that
we don't have at testing time.
Please, please, please, please don't add more things to the list. After
all, it sais there'll be cake when we remove it entirely!

This PR introduces backward compatibility index tests to test the rolling upgrade process amongst Elasticsearch instances within the same major version. The test executes in three phases. In the first phase, we form a cluster of 2 ES instances on an old version. In the second phase, we keep one of the nodes from the old cluster, kill the other node, but preserve its data directory and start an instance of the current version of ES using the same data directory as the killed instance. In the third phase, we kill the other old version ES instance from the first phase and launch a new instance, using the same data directory as the killed instance. Therefore, during phase 3, we have fully migrated and have all current versions of ES running. In each phase, we run REST tests that index documents and search them, ensuring at each stage that the documents from the previous phase are still there.
Note that because we haven't released a GA yet of 5.0, the tests currently don't start an old version cluster in the first phase. Once GA is released, this will be changed to make the backward compatibility version 5.0, while the current version in the cluster will be 5.x.
automatically between tasks, as we want some of the nodes from
the previous task to continue running in the next task. This
commit enables a cluster configuration setting to not stop
nodes automatically after a task runs, but instead the creator
of the test task must stop the running nodes explicitly in a
cleanup phase.
cluster, we wait for the cluster health to indicate the
necessary nodes have formed a cluster. This check was an
exact value (equality) check. However, if we are trying to
connect the nodes in the cluster to nodes from a previously
formed cluster (of the same name), then we will have more
nodes returned by the cluster health check than the current
task's configured number of nodes. Hence, this check needs
to be a >= check. This commit fixes it.

SearchParseElement is renamed to FetchSubPhaseParser and moved to the search.fetch package. Its parse method doesn't get the SearchContext as argument anymore, only the XContentParser, and the return type is what gets parsed (the fetch sub phase context which we may as well rename later).
It is the parser that initializes the FetchSubPhaseContext then. SearchService retrieves the parser by name, calls parse against it and stores the result of parsing by name. No need for FetchSubPhase.ContextFactory anymore, which can be removed.

If elasticsearch controls the ID values as well as the documents
version we can optimize the code that adds / appends the documents
to the index. Essentially we an skip the version lookup for all
documents unless the same document is delivered more than once.
On the lucene level we can simply call IndexWriter#addDocument instead
of #updateDocument but on the Engine level we need to ensure that we deoptimize
the case once we see the same document more than once.
This is done as follows:
1. Mark every request with a timestamp. This is done once on the first node that
receives a request and is fixed for this request. This can be even the
machine local time (see why later). The important part is that retry
requests will have the same value as the original one.
2. In the engine we make sure we keep the highest seen time stamp of "retry" requests.
This is updated while the retry request has its doc id lock. Call this `maxUnsafeAutoIdTimestamp`
3. When the engine runs an "optimized" request comes, it compares it's timestamp with the
current `maxUnsafeAutoIdTimestamp` (but doesn't update it). If the the request
timestamp is higher it is safe to execute it as optimized (no retry request with the same
timestamp has been run before). If not we fall back to "non-optimzed" mode and run the request as a retry one
and update the `maxUnsafeAutoIdTimestamp` unless it's been updated already to a higher value

Add support for a RestClient base path
Rest test suites are currently only the directory above the yaml test

which contain yaml tests, as there are in generated docs tests. This
change makes rest tests use the full relative path to the rest test root
as the suite name, and also makes the test names for docs tests a little
clearer (that they are testing an example from a specific line number,
instead of just the line number as an opaque test name).
While removing an index isn't actually an alias action, if we add
an alias action that deletes an index then we can delete and index
and add an alias with the same name as the index atomically, in
the same cluster state update.

This changes Elasticsearch to automatically downgrade `text` and
`keyword` fields into appropriate `string` fields when changing the
mapping of indexes imported from 2.x. This allows users to use the
modern, documented syntax against 2.x indexes. It also makes it clear
that reindexing in order to recreate the index in 5.0 is required for
any long lived indexes. This change is useful for the times when you
can't (cluster is just starting, not stable enough for reindex) or
shouldn't (index will only live 90 days or something).
Adds an explicit recoverySource field to ShardRouting that characterizes the type of recovery to perform:
- fresh empty shard copy
- existing local shard copy
- recover from peer (primary)
- recover from snapshot
- recover from other local shards on same node (shrink index action)
This was previously broken because run and integTest used the same
configuration name. This change makes the configuration name prefixed by
the task the cluster is created for.
In 1e91f3b we disabled annotation processors globally. However, some
project like JMH need annotation processing, so we add an ability to
selectively enabled annotation processing for certain projects by
setting an external property in the corresponding Gradle build script.
Note that `javac` would allow to set a specific annotation processor
with the command line option `-processor`. However, due to a bug in
Gradle we we cannot use this option and need to enable all annotation
processors.
This commit sets external nodes for integration tests to default to
using 512m of heap. This can be overridden using tests.heap.size (a
system property that we already use elesewhere for setting the size of
the heap for the test runner) or using tests.jvm.argline (this last one
takes precedence).
Squashes all the subpackages of `org.elasticsearch.rest.action` down to
the following:
* `o.e.rest.action.admin` - Administrative actions
* `o.e.rest.action.cat` - Actions that make tables for `grep`ing
* `o.e.rest.action.document` - Actions that act on documents
* `o.e.rest.action.ingest` - Actions that act on ingest pipelines
* `o.e.rest.action.search` - Actions that search
I'm tempted to merge `search` into `document` but the `document`
package feels fairly complete as is and `Suggest` isn't actually always
about documents either....
I'm also tempted to merge `ingest` into `admin.cluster` because the
latter contains the actions for dealing with stored scripts.
I've moved the `o.e.rest.action.support` into `o.e.rest.action`.
I've also added `package-info.java`s to all packges in `o.e.rest`. I
figure if the package is too small to deserve a `package-info.java` file
then it is too small to deserve to be a package....
Also fixes checkstyle in all moved classes.
We have 1074 snippets that look like they should be converted to

obvious ones this cuts the remaining snippet count to 1032.

Adds `warnings` syntax to the yaml test that allows you to expect
a `Warning` header that looks like:
```
- do:
warnings:
- '[index] is deprecated'
- quotes are not required because yaml
- but this argument is always a list, never a single string
- no matter how many warnings you expect
get:
index: test
type: test
id: 1
```
These are accessible from the docs with:
```
// TEST[warning:some warning]
```
This should help to force you to update the docs if you deprecate
something. You *must* add the warnings marker to the docs or the build
will fail. While you are there you *should* update the docs to add
deprecation warnings visible in the rendered results.
The `loggerUsageCheck` can only run on directories that exist. It was

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.

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.
Once all of these are migrated we'll be able to remove aggregation's
custom "streams" which function that same as NamedWriteable. It also
allows us to make most of the fields on aggregations final which is
rather nice.
The internal representation of the object that JsonPath gives access to is a map. That is independent of the initial input format, which is json but could also be yaml etc.
This commit renames JsonPath to ObjectPath and adds a static method to create an ObjectPath from an XContent
We introduced a special response_body assertion to test our docs snippets. The match assertion does the same job though and can be reused and adapted where needed. ResponseBodyAssertion contains provides much better and accurate errors though, which can be now utilized in MatchAssertion so that many more REST tests can benefit from readable error messages.
Each response body gets always stashed and can be retrieved for later evaluations already. Instead of providing the response body as strings that get parsed to json objects separately, then converted to maps as ResponseBodyAssertion did, we parse everything once, the json is part of the yaml test, which is supported. The only downside is that json comments cannot be used, rather yaml comments should be used (// C style vs # ). There were only two docs tests that were using comments in ingest-node.asciidoc where I went ahead and remove the comments which didn't seem that useful anyways.

Instead of plugins calling `registerTokenizer` to extend the analyzer
they now instead have to implement `AnalysisPlugin` and override
`getTokenizer`. This lines up extending plugins in with extending
scripts. This allows `AnalysisModule` to construct the `AnalysisRegistry`
immediately as part of its constructor which makes testing anslysis
much simpler.
This also moves the default analysis configuration into `AnalysisModule`
which is how search is setup.
Like `ScriptModule`, `AnalysisModule` no longer extends `AbstractModule`.
Instead it is only responsible for building `AnslysisRegistry`. We still
bind `AnalysisRegistry` but we only do so in `Node`. This is means it
is available at module construction time so we slowly remove the need to
bind it in guice.

This change removes some unnecessary dependencies from ClusterService
and cleans up ClusterName creation. ClusterService is now not created

Projects that don't depend on elasticsearch-test fail otherwise because org.elasticsearch.test.EsIntegTestCase (default integ test class) is not in the classpath. They should provide their onw integ test base class, but having integration tests should not be mandatory. One can simply set skipIntegTestsInDisguise to true to prevent loading of integ test class.
Today we have a push model for registering basically anything. All our extension points
are defined on modules which we pass in to plugins. This is harder to maintain and adds
unnecessary dependencies on the modules itself. This change moves towards a pull model
where the plugin offers a getter kind of method to get the extensions. This will also
help in the future if we need to pass dependencies to the extension points which can
easily be defined on the method as arguments if a pull model is used.
With this commit we add a benchmarks project that contains the necessary build

This will let things that don't depend on :test:framework like the

Also skip initializing the classes we check because we don't care

This makes the naming conventions check pretty close to instant

Groovy does some crazy capturing when using closures inside a loop. In
this case, it somehow decided the local loop variable would be
modified, and so each closure was getting a wrapped value that would be
updated on each loop iteration, until all the closures pointed at the
last value. This change fixes the loop to extract the object to be used by
the closures.
Testability of ICSS is achieved by introducing interfaces for IndicesService, IndexService and IndexShard. These interfaces extract all relevant methods used by ICSS (which do not deal directly with store) and give the possibility to easily mock all the store behavior away in the tests (and cuts down on dependencies).

and adding a test plugin there felt just wrong to me. I think this is ok. I left a tiny ingest rest test behind in that tests with an empty pipeline.
Removed messy tests, these tests were already covered in the rest tests
Added ingest test plugin in test infra so that each module testing integration with ingest doesn't need write its own plugin
Moved reindex ingest tests to qa module
Closes#18490
This adds support for setting the refresh request parameter to
`wait_for` in the `index`, `delete`, `update`, and `bulk` APIs. When
`refresh=wait_for` is set those APIs will not return until their
results have been made visible to search by a refresh.
Also it adds a `forced_refresh` field to the response of `index`,
`delete`, `update`, and to each item in a bulk response. This will
be true for requests with `?refresh` or `?refresh=true` and will be
true for some requests (see below) with `refresh=wait_for` but ought
to otherwise always be false.
`refresh=wait_for` is implemented as a list of
`Tuple<Translog.Location, Consumer<Boolean>>`s in the new `RefreshListeners`
class that is managed by `IndexShard`. The dynamic, index scoped
`index.max_refresh_listeners` setting controls a maximum number of
listeners allowed in any shard. If more than that many listeners
accumulate in the engine then a refresh will be forced, the thread that
adds the listener will be blocked until the refresh completes, and then the
listener will be called with a `forcedRefresh` flag so it knows that it was
the "straw that broke the camel's back". These listeners are only used by
`refresh=wait_for` and that flag manifests itself as `forced_refresh` being
`true` in the response.
About half of this change comes from piping async-ness down to the appropriate
layer in a way that is compatible with the ongoing with with sequence ids.
Closes#1063

Handle hanging documents
If a document is added to the index during a refresh we weren't properly
firing its refresh listener. This happened because the way we detect
whether a refresh makes something visible or not is imperfect. It is
ok because it always errs on the side of thinking that something isn't
yet visible.
So when a document arrives during a refresh the refresh listeners
won't think it made it into a refresh when, often, it does. The way
we work around this is by telling Elasticsearch that it ought to
trigger a refresh if there are any pending refresh listeners even
if there aren't pending documents to update. Lucene short circuits
the refresh so it doesn't take that much effort, but the refresh
listeners still get the signal that a refresh has come in and they
still pick up the change and notify the listener.
This means that the time that a listener can wait is actually slightly
longer than the refresh interval.

Remove Translog#lastWriteLocation
I wasn't being careful enough with locks so it wasn't right anyway.
Instead this builds a synthetic Tranlog.Location when you call
getWriteLocation with much more relaxed equality guarantees. Rather
than being equal to the last Translog.Location returned it is
simply guaranteed to be greater than the last translog returned
and less than the next.

Move refresh listeners into their own class
They still live at the IndexShard level but they live on their
own in RefreshListeners which interacts with IndexShard using a
couple of callbacks and a registration method. This lets us test
the listeners without standing up an entire IndexShard. We still
test the listeners against an InternalEngine, because the interplay
between InternalEngine, Translog, and RefreshListeners is complex
and important to get right.

Never reply to replica actions while you have the operation lock
This last thing was causing periodic test failures because we were
replying while we had the operation lock. Now, we probably could get
away with that in most cases but the tests don't like it and it isn't
a good idea to do network io while you have a lock anyway. So this
prevents it.

Create ReplicatedMutationRequest
Superclass for index, delete, and bulkShard requests.

Create TransportReplicatedMutationAction
It is the superclass of replication actions that mutate data: index, delete,
and shardBulk. shardFlush and shardRefresh are replication actions but they
do not extend TransportReplicatedMutationAction because they don't change
the data, only shuffle it around.
* [TEST] wait for yellow after setup doc tests
We have many places in the doc where we expect and index to be
yellow before we execute a query. Therefore we have to
always wait for yellow after setup.
We still have a wrapper called RestTestClient that is very specific to Rest tests, as well as RestTestResponse etc. but all the low level bits around http connections etc. are now handled by RestClient.
If this option is enabled on a processor it silently catches any processor related failure and continues executing the rest of the pipeline.
Closes#18493
There is no reason to read the entire marvel hero file to test the features,
it might take several seconds to do so which is unnecessary.
This commit also splits SearchSuggestTests into core and modules/mustache
also add @Nighlty to forbidden API to make sure we don't use it since they won't run in CI these days.
This change makes it possible to compile a separate project with e.g. targetCompatibility 1.7. Adds specific options (compact profile) only when compiling for >= 1.8.
It came out with improvements around idea integration and language levels. This will make it possible to have the upcoming java client as a new project compiled against java 7 and have idea working on the right language level.
We currently fail on any deprecations found during the build. However,
this includes things deprecated within ES, which adds a heavy burden in
order to deprecate apis (requring to add suppressions to all internal
callers of the API).
This change adds `-deprecation` to xlint. We should consider in the
future having a task to "see" what deprecated apis we currently use for
analysis.
The syntax highlighter only supports [source,js].
Also adds a check to the rest test generator that runs during
the build that'll fail the build if it sees `[source,json]`.
Significant changes:
* AbstractQueryTestCase has moved to the test framework module, in order for query builder tests in modules and plugins
* Added support to AbstractQueryTestCase to register plugins
* Lift the restriction that only one percolator could be added per index. This validation existed in MapperService, but because the percolator moved to a module it could no longer exist there. Instead of bringing it back it was removed. This validation existed since the percolator cache only supported one percolator query per document, since the percolator cache has been removed this restriction could removed as well.
* While moving percolator tests to the new module, also removed a couple of tests for the deprecated percolate and mpercolate api. These APIs are now sugar APIs for bwc and rediect to the searvh and msearvh APIs. Some tests were still testing as if percolate and mpercolate API did the percolation, but this no longer the case and these tests could be removed.
This now requires that system properties passed to Gradle must be in the form of "-Dtests.es.*" instead of
"-Des.*". It then chops off "tests.es." and passes that as a "-E" property to Elasticsearch.
Also changed system properties:
- `tests.logger.level` became `tests.es.logger.level`
- `node.mode` became `tests.es.node.mode`
- `node.local` became `tests.es.node.local`
This change makes ES compile with java9 again, build 118.
* There are a handful of changes due to failure to determine types during compile.
* The attachment plugins which use tika needed to have tika upgraded in order to pickup fixes there for java 9.
* azure discovery and s3 repository indirectly depend on jaxb, which is no longer in the default modules. They now add a jaxb dependency externally, and make JarHell allow for this package.
This commit passes the system property tests.logger.level down to the
external nodes launched in integration tests. Specific tests that want
to override the default logging level should push down a setting to
the nodes using cluster configuration instead of pushing down a system
property to the nodes using cluster configuration.
Relates #18489
Today when parsing settings during bootstrap, we add a system property
for every Elasticsearch setting. Additionally, settings can be set via
system properties. This commit simplifies this situation.
- settings are no longer propogated to system properties
- system properties can not be used to set settings
- the "es." prefix on settings is no longer required (nor permitted)
- test logging has a dedicated system property (tests.logger.level)

Two of the snippets in validate weren't working properly so they are
marked as skip and linked to this:
https://github.com/elastic/elasticsearch/issues/18254
We didn't properly handle empty parameter values. We were sending
them as the literal string "null". Now we do better and send them
as the empty string.
This commit refactors the JvmGcMonitorService so that it can be
tested. In particular, hooks are added to verify that the
JvmMonitorService correctly observes slow GC events, and that the
JvmGcMonitorService logs the correct messages.

(same name and UUID) exists in the cluster state. This resolves a
situation where if an index data folder was copied into a node's data
directory while the node is running and that index had a tombstone in
the cluster state, the index would still get imported.
Closes#18250Closes#18249
This makes it much easier to apply to other projects.
Fixes to doc tests infrastructure:
* Fix comparing lists. Was totally broken.
* Fix order of actual vs expected parameters.
* Allow multiple `// TESTRESPONSE` lines with substitutions to join
into one big list of subtitutions. This makes lets the docs look
tidier.
* Exclude build from snippet scanning
* Allow subclasses of ESRestTestCase access to the admin execution context
This is a follow up to #18173 and includes adding pom generation to the
fake build-tools project, which is really just buildSrc, but builds
during normal builds.
In preparation for a unified release process, we need to be able to
generate the pom files independently of trying to actually publish. This
change adds back the maven-publish plugin just for that purpose. The
nexus plugin still exists for now, so that we do not break snapshots,
but that can be removed at a later time once snapshots are happenign
through the unified tools. Note I also changed the dir jars are written
into so that all our artifacts are under build/distributions.
This was broken recently as part of making the vagrant tasks extend
LoggedExec. This change fixes the progress logger to not be started
until we start seeing output from vagrant.
o/e/snapshots/Snapshot and o/e/snapshots/SnapshotInfo contain the same
fields and represent the same information. Snapshot was used to
maintain snapshot information to the snapshot repository, while
SnapshotInfo was used to represent the snapshot information as presented
through the REST layer. This removes the Snapshot class and combines
all uses into the SnapshotInfo class.
Closes#18167
Adds infrastructure so `gradle :docs:check` will extract tests from
snippets in the documentation and execute the tests. This is included
in `gradle check` so it should happen on CI and during a normal build.
By default each `// AUTOSENSE` snippet creates a unique REST test. These
tests are executed in a random order and the cluster is wiped between
each one. If multiple snippets chain together into a test you can annotate
all snippets after the first with `// TEST[continued]` to have the
generated tests for both snippets joined.
Snippets marked as `// TESTRESPONSE` are checked against the response
of the last action.
See docs/README.asciidoc for lots more.
Closes#12583. That issue is about catching bugs in the docs during build.
This catches *some* bugs in the docs during build which is a good start.
This change makes the vagrant tasks extend LoggedExec, so that the
entire vagrant output can be dumped on failure (and completely logged
when using --info). It should help for debugging issues like #18122.
This change fixes the generation of plugin properties files when the
version changes. Before, it would not regenerate, and running integTest
would fail with an incompatibile version error.
Gradle has a "shortcut" which omits the target and source compatibility
we set when it thinks it is not necessary (eg gradle is running on the
same version as the target compat). However, the way we compile against
java 9 is to set javac to use java 9, while gradle still runs on java 8.
This change makes -source and -target explicit for now, until these
"optimizations" can be removed from gradle.
closes#18039
Switch something from an explicit toString to Strings.toString which
is the same thing but with more code reuse.
Also renamed a constant to be CONSTANT_CASE.
* Add isSearchable and isAggregatable (collapsed to true if any of the instances of that field are searchable or aggregatable).
* Accept wildcards in field names.
* Add a section named conflicts for fields with the same name but with incompatible types (instead of throwing an exception).
`ip` fields currently fail range queries when either bound is inclusive. This
commit makes ranges also work in the exclusive case to be consistent with other
data types.
Replace with a constructor that takes StreamInput or a static method.
In one case (ValuesSourceType) we no longer need to serialize the data
at all!
Relates to #17085
Extracts all the replication logic that is done on the Primary to a separated class called ReplicationOperation. The goal
here is to make unit testing of this logic easier and in the future allow setting up tests that work directly on IndexShards
without the need for networking.
Closes#16492
The checkstyle configuration files were being accessed as resources within the project and
being converted from a URL to a File by gradle. This works when the build tools project is being
referenced as a local project. However, when using the published jar the URL points to a resource
in the jar file, that URL cannot be converted to a File object and causes the build to fail.
This change copies the files into a `checkstyle` directory in the project build folder and always uses
File objects pointing to the copied files.
This makes all numeric fields including `date`, `ip` and `token_count` use
points instead of the inverted index as a lookup structure. This is expected
to perform worse for exact queries, but faster for range queries. It also
requires less storage.
Notes about how the change works:
- Numeric mappers have been split into a legacy version that is essentially
the current mapper, and a new version that uses points, eg.
LegacyDateFieldMapper and DateFieldMapper.
- Since new and old fields have the same names, the decision about which one
to use is made based on the index creation version.
- If you try to force using a legacy field on a new index or a field that uses
points on an old index, you will get an exception.
- IP addresses now support IPv6 via Lucene's InetAddressPoint and store them
in SORTED_SET doc values using the same encoding (fixed length of 16 bytes
and sortable).
- The internal MappedFieldType that is stored by the new mappers does not have
any of the points-related properties set. Instead, it keeps setting the index
options when parsing the `index` property of mappings and does
`if (fieldType.indexOptions() != IndexOptions.NONE) { // add point field }`
when parsing documents.
Known issues that won't fix:
- You can't use numeric fields in significant terms aggregations anymore since
this requires document frequencies, which points do not record.
- Term queries on numeric fields will now return constant scores instead of
giving better scores to the rare values.
Known issues that we could work around (in follow-up PRs, this one is too large
already):
- Range queries on `ip` addresses only work if both the lower and upper bounds
are inclusive (exclusive bounds are not exposed in Lucene). We could either
decide to implement it, or drop range support entirely and tell users to
query subnets using the CIDR notation instead.
- Since IP addresses now use a different representation for doc values,
aggregations will fail when running a terms aggregation on an ip field on a
list of indices that contains both pre-5.0 and 5.0 indices.
- The ip range aggregation does not work on the new ip field. We need to either
implement range aggs for SORTED_SET doc values or drop support for ip ranges
and tell users to use filters instead. #17700Closes#16751Closes#17007Closes#11513
This commit contains the following improvements/fixes:
1. Renaming method names and variables to better reflect the purpose
of the method and the semantics of the variable.
2. For deleting indexes, replace the closed parameter passed to the
delete index/store methods with obtaining the index's state from the
IndexSettings that is already passed in.
3. Added tests to the IndexWithShadowReplicaIT suite, some of which
show issues in the shadow replica delete process that are captured in
Github issue 17695.

This commit removes the last remaining uses of JAVA_OPTS. Now searching
the codebase for the regex '(?<!ES_)JAVA_OPTS' only shows the uses
warning of its removal and the note about it in the migration docs.
* Tokens in the same position are grouped into a SynonymQuery..
* The default operator is applied on tokens in different positions.
* The wildcard is applied to the terms in the last position only.
Fixes#2183
When an index is recovered from disk it's metadata is imported first and the master reaches out to the nodes looking for shards of that index. Sometimes those requests reach other nodes before the cluster state is processed by them. At the moment, that situation disables the checking of the store, which requires the meta data (indices with custom path need to know where the data is). When corruption hits this means we may assign a shard to node with corrupted store, which will be caught later on but causes confusion. Instead we can try loading the meta data from disk in those cases.
Relates to #17630
* upgrades numerics to new Point format
* updates geo api changes
* adds GeoPointDistanceRangeQuery as XGeoPointDistanceRangeQuery
* cuts over to ES GeoHashUtils
* Create one AllField field per field eligible for _all.
* Add a positionIncrementGap (with a size of 100, not configurable) between
each entry in order to distinguish fields when doing phrase query on _all.
This removes PROTOTYPEs from ScoreFunctionsBuilders. To do so we rework
registration so it doesn't need PROTOTYPEs and lines up with the recent
changes to query registration.
* [TEST] check registered queries one by one in SearchModuleTests
* Switch to using ParseField to parse query names
If we have a deprecated query name, at the moment we don't have a way to log any deprecation warning nor fail when we are in strict mode. With this change we use ParseField, which will take care of the camel casing that we currently do manually (so that one day we can remove it more easily). This also means, that each query will have a unique preferred name, and all the other names are deprecated.
Terms query "in" synonym is now formally deprecated, as well as fuzzy_match, match_fuzzy, match_phrase and match_phrase_prefix for match query, mlt for more_like_this and geo_bbox for geo_bounding_box. All these will be removed in 6.0.
Every QueryParser holds now a ParseField constant called QUERY_NAME_FIELD that holds the name for it. The first name is the preferred one, all the others are deprecated. The first name is taken from the NAME constant already present in each query builder object, so that we somehow keep the serialization constant separated from ParseField. This change also allowed us to remove the names method from the QueryParser interface.
This commit introduces SearchOperationListeneres which allow to hook
into search operation lifecycle and execute operations like slow-logs
and statistic collection in a transparent way. SearchOperationListenrs
can be registered on the IndexModule just like IndexingOperationListeners.
The main consumers (slow log) have already been moved out of IndexService
into IndexModule which reduces the dependency on IndexService as well as
IndexShard and makes slowlogging transparent.
Closes#17398
Today the basic node settings like `node.data` and `node.master` can't really be fully validated
since we allow to specify custom user attributes on the node level. We have to, in order to
support that, add a wildcard setting for `node.*` to let these setting pass validation.
Instead we should require a more contraint prefix like `node.attr.` that defines a namespace
that is reserved for user attributes.
This commit adds a new namespace for attributes in `node.attr`.
Closes#17280
When we test we add `-Djna.nosys=true` to the system properties but
we don't add it to system properties when running the naming conventions
test. This was causing the build to fail on a newly minted Ubuntu 15.10
machine, presumably because I made the mistake of installing maven using
the system package manager.
This adds a new `/_cluster/allocation/explain` API that explains why a
shard can or cannot be allocated to nodes in the cluster. Additionally,
it will show where the master *desires* to put the shard, according to
the `ShardsAllocator`.
It looks like this:
```
GET /_cluster/allocation/explain?pretty
{
"index": "only-foo",
"shard": 0,
"primary": false
}
```
Though, you can optionally send an empty body, which means "explain the
allocation for the first unassigned shard you find".
The output when a shard is unassigned looks like this:
```
{
"shard" : {
"index" : "only-foo",
"index_uuid" : "KnW0-zELRs6PK84l0r38ZA",

Only "NO" decisions are returned by default, but all decisions can be
shown by specifying the `?include_yes_decisions=true` parameter in the
request.
Resolves#14593
Node roles are now serialized as well, they are not part of the node attributes anymore. DiscoveryNodeService takes care of dividing settings into attributes and roles. DiscoveryNode always requires to pass in attributes and roles separately.
readFrom is confusing because it requires an instance of the type that it
is reading but it doesn't modify it. But we also have (deprecated) methods
named readFrom that *do* modify the instance. The "right" way to implement
the non-modifying readFrom is to delegate to a constructor that takes a
StreamInput so that the read object can be immutable. Now that we have
`@FunctionalInterface`s it is fairly easy to register things by referring
directly to the constructor.
This change modifying NamedWriteableRegistry so that it does that. It keeps
supporting `registerPrototype` which registers objects to be read by
readFrom but deprecates it and delegates it to a new `register` method
that allows passing a simple functional interface. It also cuts Task.Status
subclasses over to using that method.

We already archive index level settings if we find an unknown or invalid/broken
value for a setting on node startup. The same could potentially happen for persistent
cluster level settings if we remove a setting or if we add validation to a setting that
didn't exist in the past. To ensure that only valid settings are recovered into the cluster
state we archive them (prefix them with `archive.` and log a warning. Tools that check the
cluster settings can then warn users that they have broken settings in their clusterstate that
got archived.
This commit fixes string formatting issues in the error handling and
provides a bettter error message if malformed input is detected.
This commit also adds tests for both situations.
Relates to #17212
this is the last step to remove node level service from IndexShard.
This means that tests can now more easily create an IndexShard instance
without starting a node and removes the dependency between IndexShard and Client/ScriptService
Today if something is wrong with the IndexMetaData we detect it very
late and most of the time if that happens we already allocated the index
and get endless loops and full log files on data-nodes. This change tries
to verify IndexService creattion during initial state recovery on the master
and if the recovery fails the index is imported as `closed` and won't be allocated
at all.
Closes#17187
We current have a ClusterService interface, implemented by InternalClusterService and a couple of test classes. Since the decoupling of the transport service and the cluster service, one can construct a ClusterService fairly easily, so we don't need this extra indirection.

Also replaced the PercolatorQueryRegistry with the new PercolatorQueryCache.
The PercolatorFieldMapper stores the rewritten form of each percolator query's xcontext
in a binary doc values field. This make sure that the query rewrite happens only during
indexing (some queries for example fetch shapes, terms in remote indices) and
the speed up the loading of the queries in the percolator query cache.
Because the percolator now works inside the search infrastructure a number of features
(sorting fields, pagination, fetch features) are available out of the box.
The following feature requests are automatically implemented via this refactoring:

This commit fixes the line-length checkstyle violations in
InstallPluginCommand.java and removes this from the list of files for

Today we allow to set all kinds of index level settings on the node level which
is error prone and difficult to get right in a consistent manner.
For instance if some analyzers are setup in a yaml config file some nodes might
not have these analyzers and then index creation fails.
Nevertheless, this change allows some selected settings to be specified on a node level
for instance:
* `index.codec` which is used in a hot/cold node architecture and it's value is really per node or per index
* `index.store.fs.fs_lock` which is also dependent on the filesystem a node uses
All other index level setting must be specified on the index level. For existing clusters the index must be closed
and all settings must be updated via the API on each of the indices.
Closes#16799
Adds support for scheduling commands to run at a later time on another
thread pool in the current thread's context:
```java
Runnable someCommand = () -> {System.err.println("Demo");};
someCommand = threadPool.getThreadContext().preserveContext(someCommand);
threadPool.schedule(timeValueMinutes(1), Names.GENERAL, someCommand);
```
This happens automatically for calls to `threadPool.execute` but `schedule`
and `scheduleWithFixedDelay` don't do that, presumably because scheduled
tasks are usually context-less. Rather than preserve the current context
on all scheduled tasks this just makes it possible to preserve it using
the syntax above.
To make this all go it moves the Runnables that wrap the commands from
EsThreadPoolExecutor into ThreadContext.
This, or something like it, is required to support reindex throttling.
The build currently uses the old maven support in gradle. This commit
switches to use the newer maven-publish plugin. This will allow future
changes, for example, easily publishing to artifactory.
An additional part of this change makes publishing of build-tools part
of the normal publishing, instead of requiring a separate upload step
from within buildSrc. That also sets us up for a follow up to enable
precomit checks on the buildSrc code itself.
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
any dedicated BWC tests but rather leverages the existing REST tests.
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.
Relates to #14406Closes#17072
Today we use hardcoded ports to form a cluster in the mulit-node case.
The hardcoded URIs are passed to the unicast host list which is error prone and
might cause problems if those ports are exhausted etc. This commit moves to a
less error prone way of forming the cluster where all nodes are started with port `0`
and all but the first node wait for the first node to write it's ports file to form a
cluster. This seed node is enough to form a cluster.
We removed leniencey from version parsing which caught problems with
-SNAPSHOT suffixes on plugin properies. This commit removes the -SNAPSHOT
from both es and the extension version and adds tests to ensure we can
parse older versions that allowed -SNAPSHOT in BWC way.
