This commit renames all rest test files to use the .yml extension
instead of .yaml. This way the extension used within all of
elasticsearch for yaml is consistent.
Today when an index is `read-only` the index is also blocked from
being deleted which sometimes is undesired since in-order to make
changes to a cluster indices must be deleted to free up space. This is
a likely scenario in a hosted environment when disk-space is limited to switch
indices read-only but allow deletions to free up space.
* Add parent-join module
This change adds a new module named `parent-join`.
The goal of this module is to provide a replacement for the `_parent` field but as a first step this change only moves the `has_child`, `has_parent` queries and the `children` aggregation to this module.
These queries and aggregations are no longer in core but they are deployed by default as a module.

If the request asks for the `_source` stored field then don't
duplicate it when forcing the `_source` parameter to onto the
request for reindex-from-remote from versions before 1.0.
Closes#24628
This allows other plugins to use a client to call the functionality
that is in the core modules without duplicating the logic.
Plugins can now safely send the request and response classes via the
client even if the requests are executed locally. All relevant classes
are loaded by the core classloader such that plugins can share them.

Adds tests for reindex-from-remote for the latest 2.4, 1.7, and
0.90 releases. 2.4 and 1.7 are fairly popular versions but 0.90
is a point of pride.
This fixes any issues those tests revealed.

This change makes the request builder code-path same as `Client#execute`. The request builder used to return a `ListenableActionFuture` when calling execute, which allows to associate listeners with the returned future. For async execution though it is recommended to use the `execute` method that accepts an `ActionListener`, like users would do when using `Client#execute`.

This adds the `index.mapping.single_type` setting, which enforces that indices
have at most one type when it is true. The default value is true for 6.0+ indices
and false for old indices.

The one argument ctor for `Script` creates a script with the
default language but most usages of are for testing and either
don't care about the language or are for use with
`MockScriptEngine`. This replaces most usages of the one argument
ctor on `Script` with calls to `ESTestCase#mockScript` to make
it clear that the tests don't need the default scripting language.
I've also factored out some copy and pasted script generation
code into a single place. I would have had to change that code
to use `mockScript` anyway, so it was easier to perform the
refactor.

The unwrap method was leftover from support javascript and python. Since
those languages are removed in 6.0, this commit removes the unwrap
feature from scripts.
This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.

When indexing a document via the bulk API where IDs can be explicitly
specified, we currently accept an empty ID. This is problematic because
such a document can not be obtained via the get API. Instead, we should
rejected these requets as accepting them could be a dangerous form of
leniency. Additionally, we already have a way of specifying
auto-generated IDs and that is to not explicitly specify an ID so we do
not need a second way. This commit rejects the individual requests where
ID is specified but empty.
Relates #24118
This commit collapses the SyncBulkRequestHandler and
AsyncBulkRequestHandler into a single BulkRequestHandler. The new
handler executes a bulk request and awaits for the completion if the
BulkProcessor was configured with a concurrentRequests setting of 0.
Otherwise the execution happens asynchronously.
As part of this change the Retry class has been refactored.
withSyncBackoff and withAsyncBackoff have been replaced with two
versions of withBackoff. One method takes a listener that will be
called on completion. The other method returns a future that will been
complete on request completion.
reindex_from_remote was using `TimeValue#toString` to generate the
scroll timeout which is bad because that generates fractional
time values that are useful for people but bad for Elasticsearch
which doesn't like to parse them. This switches it to using
`TimeValue#getStringRep` which spits out whole time values.
Closes to #23945
Makes #23828 even more desirable
This commit modifies the BulkProcessor to be decoupled from the
client implementation. Instead it just takes a
BiConsumer<BulkRequest, ActionListener<BulkResponse>> that executes
the BulkRequest.
This commit renames the random ASCII helper methods in ESTestCase. This
is because this method ultimately uses the random ASCII methods from
randomized runner, but these methods actually only produce random
strings generated from [a-zA-Z].
Relates #23886
As the query of a search request defaults to match_all,
calling _delete_by_query without an explicit query may
result in deleting all data.
In order to protect users against falling into that
pitfall, this commit adds a check to require the explicit
setting of a query.
Closes#23629
Changes reindex and friends to wait until the entire request has
been "cleaned up" before responding. "Clean up" in this context
is clearing the scroll and (for reindex-from-remote) shutting
down the client. Failures to clean up are still only logged, not
returned to the user.
Closes#23653
We have many version constants in master that have already been
released, but are still marked (by naming convention) as unreleased.
This commit renames those version constants.
Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).
This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`. The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.
This commit enforces the requirement of Content-Type for the REST layer and removes the deprecated methods in transport
requests and their usages.
While doing this, it turns out that there are many places where *Entity classes are used from the apache http client
libraries and many of these usages did not specify the content type. The methods that do not specify a content type
explicitly have been added to forbidden apis to prevent more of these from entering our code base.
Relates #19388
We have a bunch of interfaces that have only a single implementation
for 6 years now. These interfaces are pretty useless from a SW development
perspective and only add unnecessary abstractions. They also require
lots of casting in many places where we expect that there is only one
concrete implementation. This change removes the interfaces, makes
all of the classes final and removes the duplicate `foo` `getFoo` accessors
in favor of `getFoo` from these classes.
As part of #22116 we are going to forbid usage of api
java.net.URL#openStream(). However in a number of places across the
we use this method to read files from the local filesystem. This commit
introduces a helper method openFileURLStream(URL url) to read files
from URLs. It does specific validation to only ensure that file:/
urls are read.
Additionlly, this commit removes unneeded method
FileSystemUtil.newBufferedReader(URL, Charset). This method used the
openStream () method which will soon be forbidden. Instead we use the
Files.newBufferedReader(Path, Charset).
This test was using initial count of slices instead of the count
of unfinished slices to pick the expected throttle. Unfortunely
due to race conditions the actual rethrottle count is between the
two. So we weaken the assertion from "the new throttle is exactly X"
to "the new throttle is between X and Y (inclusive)".
This is related to #22116. Core no longer needs `SocketPermission`
`connect`.
This permission is relegated to these modules/plugins:
- transport-netty4 module
- reindex module
- repository-url module
- discovery-azure-classic plugin
- discovery-ec2 plugin
- discovery-gce plugin
- repository-azure plugin
- repository-gcs plugin
- repository-hdfs plugin
- repository-s3 plugin
And for tests:
- mocksocket jar
- rest client
- httpcore-nio jar
- httpasyncclient jar
Versions of Elasticsearch prior to 2.0 would return a scroll id
even with the last scroll response. They'd then automatically
clear the scroll because it is empty. When terminating reindex
will attempt to clear the last scroll it received, regardless of
the remote version. This quiets the warning when the scroll cannot
be cleared for versions before 2.0.

This commit upgrades the checkstyle configuration from version 5.9 to

`UpdateByQueryWhileModifyingTests#testUpdateWhileReindexing`
runs update-by-query and concurrently updates, asserting that
the update-by-query never reverts any changes made by the update.
It is a smoke test for concurrent updates.
Now, it expects to hit a certain number of version conflicts
during the updates. This is normal as it is racing the
update-by-query. We have a maximum number of failures we
expect (10) and I'd never seen us come close until
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+5.x+multijob-unix-compatibility/os=sles/495/console
This bumps the max failures from 10 to 50 and improves
logging a bit. If we continue to see this failure then we have
some other issue.
Closes#22938
This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.
The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.
As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.
In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.
See #19388
In 5.2 we stopped sending the source parameter if the user didn't
specify it. This was a mistake as versions before 2.0 look like
they don't always include the `_source`. This is because reindex
requests some metadata fields. Anyway, now we say `"_source": true`
if there isn't a `_source` configured in the reindex request.
Closes#22893
This moves the building blocks for delete by query into core. This
should enabled two thigns:
1. Plugins other than reindex to implement "bulk by scroll" style
operations.
2. Plugins to directly call delete by query. Those plugins should
be careful to make sure that task cancellation still works, but
this should be possible.
Notes:
1. I've mostly just moved classes and moved around tests methods.
2. I haven't been super careful about cohesion between these core
classes and reindex. They are quite interconnected because I wanted
to make the change as mechanical as possible.
Closes#22616
This adds the necessary `AuthCache` needed to support preemptive authorization. By adding every host to the cache, the automatically added `RequestAuthCache` interceptor will add credentials on the first pass rather than waiting to do it after _each_ anonymous request is rejected (thus always sending everything twice when basic auth is required).
* Add top hits collapsing to search request
The field collapsing is done with a custom top docs collector that "collapse" search hits with same field value.
The distributed aspect is resolve using the two passes that the regular search uses. The first pass "collapse" the top hits, then the coordinating node merge/collapse the top hits from each shard.
```
GET _search
{
"collapse": {
"field": "category",
}
}
```
This change also adds an ExpandCollapseSearchResponseListener that intercepts the search response and expands collapsed hits using the CollapseBuilder#innerHit} options.
The retrieval of each inner_hits is done by sending a query to all shards filtered by the collapse key.
```
GET _search
{
"collapse": {
"field": "category",
"inner_hits": {
"size": 2
}
}
}
```
There are presently 7 ctor args used in any rest handlers:
* `Settings`: Every handler uses it to initialize a logger and
some other strange things.
* `RestController`: Every handler registers itself with it.
* `ClusterSettings`: Used by `RestClusterGetSettingsAction` to
render the default values for cluster settings.
* `IndexScopedSettings`: Used by `RestGetSettingsAction` to get
the default values for index settings.
* `SettingsFilter`: Used by a few handlers to filter returned
settings so we don't expose stuff like passwords.
* `IndexNameExpressionResolver`: Used by `_cat/indices` to
filter the list of indices.
* `Supplier<DiscoveryNodes>`: Used to fill enrich the response
by handlers that list tasks.
We probably want to reduce these arguments over time but
switching construction away from guice gives us tighter
control over the list of available arguments.
These parameters are passed to plugins using
`ActionPlugin#initRestHandlers` which is expected to build and
return that handlers immediately. This felt simpler than
returning an reference to the ctors given all the different
possible args.
Breaks java plugins by moving rest handlers off of guice.
This commit adds a MessyRestTestPlugin to the gradle build. It extends
StandaloneRestTestPlugin. The main piece of functionality that it adds
is to copy plugin-metadata from dependencies into the
generated-resources for the current test source. This is necessary to
ensure that permissions for dependencies are applied when running the
tests.
A current limitation is that the permissions are applied differently
than in the distribution sources. When permissions are granted to all
depedencies for a module or plugin, the permissions are granted to all
dependencies on the classpath for tests besides a few hardcoded
exclusions:
- es core
- es test framework
- lucene test framework
- randomized runner
- junit library
Everything that extended `AbstractAsyncBulkByScrollAction` also
extended `AbstractAsyncBulkIndexByScrollAction` so this removes
`AbstractAsyncBulkIndexByScrollAction`, merging it into
`AbstractAsyncBulkByScrollAction`.
Changes the error message when `action.auto_create_index` or
`index.mapper.dynamic` forbids automatic creation of an index
from `no such index` to one of:
* `no such index and [action.auto_create_index] is [false]`
* `no such index and [index.mapper.dynamic] is [false]`
* `no such index and [action.auto_create_index] contains [-<pattern>] which forbids automatic creation of the index`
* `no such index and [action.auto_create_index] ([all patterns]) doesn't match`
This should make it more clear *why* there is `no such index`.
Closes#22435
Today we do not preserve response headers if they are present on a transport protocol
response. While preserving these headers is not always desired, in the most cases we
should pass on these headers to have consistent results for depreciation headers etc.
yet, this hasn't been much of a problem since most of the deprecations are detected early
ie. on the coordinating node such that this bug wasn't uncovered until #22647
This commit allow to optionally preserve headers when a context is restored and also streamlines
the context restore since it leaked frequently into the callers thread context when the callers
context wasn't restored again.
Instead of forcing each task to register all nodes where its children are running, this commit runs cancellation on all nodes. The task cancellation operation doesn't run too frequently, so this optimization doesn't seem to be worth additional complexity of the interface.
