The Writeble representation is less heavy to parse and that will benefit percolate performance and throughput.
The query builder's binary format has now the same bwc guarentees as the xcontent format.
Added a qa test that verifies that percolator queries written in older versions are still readable by the current version.
This commit fixes tests for environment-aware commands. A previous
change added a check that es.path.conf is not null. The problem is that
this system property is not being set in tests so this check trips every
single time. To fix this, we move the check into a method that can be
overridden, and then override this method in relevant places in tests to
avoid having to set the property in tests. We also add a test that this
check works as expected.
Today when we aggregate on the `_index` field the cross cluster search
alias is not taken into account. Neither is it respected when we search
on the field. This change adds support for cluster alias when the cluster
alias is present on the `_index` field.

This commit removes all external dependencies from the rest client jar

This commit introduces the elasticsearch-env script. The purpose of this
script is threefold:
- vastly simplify the various scripts used in Elasticsearch
- provide a script that can be included in other scripts in the
Elasticsearch ecosystem (e.g., plugins)
- correctly establish the environment for all scripts (e.g., so that
users can run `elasticsearch-keystore` from a package distribution
without having to worry about setting `CONF_DIR` first, otherwise the
keystore would be created in the wrong location)

Today if we search across a large amount of shards we hit every shard. Yet, it's quite
common to search across an index pattern for time based indices but filtering will exclude
all results outside a certain time range ie. `now-3d`. While the search can potentially hit
hundreds of shards the majority of the shards might yield 0 results since there is not document
that is within this date range. Kibana for instance does this regularly but used `_field_stats`
to optimize the indexes they need to query. Now with the deprecation of `_field_stats` and it's upcoming removal a single dashboard in kibana can potentially turn into searches hitting hundreds or thousands of shards and that can easily cause search rejections even though the most of the requests are very likely super cheap and only need a query rewriting to early terminate with 0 results.
This change adds a pre-filter phase for searches that can, if the number of shards are higher than a the `pre_filter_shard_size` threshold (defaults to 128 shards), fan out to the shards
and check if the query can potentially match any documents at all. While false positives are possible, a negative response means that no matches are possible. These requests are not subject to rejection and can greatly reduce the number of shards a request needs to hit. The approach here is preferable to the kibana approach with field stats since it correctly handles aliases and uses the correct threadpools to execute these requests. Further it's completely transparent to the user and improves scalability of elasticsearch in general on large clusters.
This commit removes the environment variable ES_JVM_OPTIONS that allows

This commit reverts a rename of the systemd packaging tests. The rename
was done locally to speed up iteration of testing some changes against
systemd but was not reverted before pushing. This commit reverts this
change.
On Debian-based systems the install scripts are run with set -e meaning
that if there is an error in executing one of these scripts then the
script fails. If systemd-sysctl is masked then trying to restart the
systemd-sysctl service to pick up the changes to vm.max_map_count will
fail leading to the post-install script failing. Instead, we should
account for the possbility of failure here by not letting the command to
restart this service exit with non-zero status code. This commit does
this, and adds a test for this situation.

In the past global checkpoint syncing was done in the background based an interval set by an index setting. In order to set that setting something reasonable for a test, the master needed to know about the setting. Therefore the test didn't check global checkpoints if the master was old. These days the global checkpoint sync is inlined with indexing operations and that restriction is not needed.
In the rolling upgrade tests, there is a test to create an index with
replica shards and ensure that in the mixed cluster environment, the
cluster health is green before any other tests are executed. However,
there were two problems with this. First, if the replica shard was
residing on the restarted node, then delayed allocation will kick in and
cause the cluster health request to timeout after 1m. The fix to this
was to drastically lower the delayed allocation setting. Second, if the
primary exists on the higher version node, then the replica cannot be
assigned to the lower version node because recovery cannot happen from
lower lucene versions. The fix here was to wait for the cluster health
to be yellow instead of green in the mixed cluster environment. In the
fully upgraded cluster, the cluster health check waits for a green
cluster as before.

Currently QueryParseContext is only a thin wrapper around an XContentParser that

QueryParseContext entirely.
When a setting is deprecated, if that setting is used repeatedly we
currently emit a deprecation warning every time the setting is used. In
cases like hitting settings endpoints over and over against a node with
a lot of deprecated settings, this can lead to excessive deprecation
warnings which can crush a node. This commit ensures that a given
setting only sees deprecation logging at most once.

This commit changes how we determine if there were any remote indices that a search should have
been executed against. Previously, we used the list of remote shard iterators but if the remote
index pattern resolved to no indices there would be no remote shard iterators even though the
request specified remote indices. The map of remote cluster names to the original indices is used
instead so that we can determine if there were remote indices even when there are no remote shard
iterators.

This commit adds a gradle project, set inside the root build.gradle,
which controls all our bwc tests. This allows for seamless (ie no errant
CI failures) backporting of behavior.
In #25201, a setting was added to allow setting the retry timeout for the rest client under the
impression that this would allow requests to go longer than 30s. However, there is also a socket
timeout that needs to be set to greater than 30s, which this change adds a setting for.
This commit adds a setting to change the request timeout for the rest client. This is useful as the
default timeout is 30s, which is also the same default for calls like cluster health. If both are
the same then the response from the cluster health api will not be received as the client usually
times out first making test failures harder to debug.

Duplicate data paths already fail to work because we would attempt to
take out a node lock on the directory a second time which will fail

the failure cause more obvious.
Relates #25178
We have a custom logger implementation known as a prefix logger that is
used to write every message by the logger with a given prefix. This is
useful for node-level, index-level, and shard-level messages where we
want to log the node name, index name, and shard ID, respectively, if
possible. The mechanism that we employ is that of a marker. Log4j has a
built-in facility for managing these markers, but its effectively a
memory leak because these markers are held in a map and can never be
released. This is problematic for us since indices and shards do not
necessarily have infinite life spans and so on a node where there are
many indices being creted and destroyed, this infinite lifespan can be a
problem indeed. To solve this, we use our own cache of markers. This is
necessary to prevent too many instances of the marker for the same
prefix from being created (just think of all the shard-level components
that exist in the system), and to workaround the effective leak in
Log4j. These markers are stored as weak references in a weak hash
map. It is these weak references that are unneeded. When a key is
removed from a weak hash map, the corresponding entry is placed on a
reference queue that is eventually cleared. This commit simplifies
prefix logger by removing this unnecessary weak reference wrapper.

This adds an option to `ClusterConfiguration` to preserve the

* Adds nodes usage API to monitor usages of actions
The nodes usage API has 2 main endpoints
/_nodes/usage and /_nodes/{nodeIds}/usage return the usage statistics

At the moment only one type of usage statistics is available, the REST
actions usage. This records the number of times each REST action class is
called and when the nodes usage api is called will return a map of rest
action class name to long representing the number of times each of the action
classes has been called.

Removes the need for the `_UNRELEASED` suffix on versions by detecting if a version should be unreleased or not based on the versions around it. This should make it simpler to automate the task of adding a new version label.
These tests spin up two nodes of an older version of Elasticsearch,
create some stuff, shut down the nodes, start the current version,
and verify that the created stuff works.
You can run `gradle qa:full-cluster-restart:check` to run these
tests against the head of the previous branch of Elasticsearch
(5.x for master, 5.4 for 5.x, etc) or you can run
`gradle qa:full-cluster-restart:bwcTest` to run this test against
all "index compatible" versions, one after the other. For master
this is every released version in the 5.x.y version *and* the tip
of the 5.x branch.
I'd love to add more to these tests in the future but these
currently just cover the functionality of the `create_bwc_index.py`
script and start to cover the assertions in the
`OldIndexBackwardsCompatibilityIT` test.
This is a simple refactoring to move the context definitions into the
type that they use. While we have multiple context names for the same
class at the moment, this will eventually become one ScriptContext per
instance type, so the pattern of a static member on the interface called
CONTEXT can be used. This commit also moves the consolidated list of
contexts provided by core ES into ScriptModule.
As we work towards contexts implying the return type of compilation, we
first need ScriptContext to not be an enum. This commit removes the
Standard enum and Plugin subclass of ScriptContext.
ScriptEngine implementations have an overridable method to indicate they
are safe to use as inline scripts. Since groovy was removed fro 6.0,
there are no longer any implementations which used the default false
value. Furthermore, the value was not actually read anywhere. This
commit removes the method. The ScriptEngineRegistry was also no longer
necessary as it only was used to build a map from language to engine.
This commit renames the backwards-5.0 qa test to mixed-cluster and
creates a test within the project per wire compat version. Like with
rolling upgrade tests, the integTest task will run against the most
recent version, while all versions will be tested with the bwcTest task.
Now that we generate the versions list from Versions.java we can
drop the list of versions maintained for vagrant testing. One nice
thing that the vagrant testing did was to check if the list of
versions was out of date. This moves that test to the core
project.
This commit changes the rolling upgrade test to create a set of rest
test tasks per wire compat version. The most recent wire compat version
is always tested with the `integTest` task, and all versions can be
tested with `bwcTest`.
This commit expands the logic for version extraction from Version.java
to include a list of all versions for backcompat purposes. The tests
using bwcVersion are converted to use this list, but those tests
(rolling upgrade and backwards-5.0) are still not randomized; that will
happen in another followup.
Today the `_field_caps` API doesn't implement its request serialization
correctly since indices and indices options are not serialized at all.
This will likely break with all transport clients etc. and if this request
must be send across the network. This commit fixes this and adds correct
handling if we have only remote indices to prevent the inclusion of
all local indices.
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.
* 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.

Today we rely on background syncs to relay the global checkpoint under
the mandate of the primary to its replicas. This means that the global
checkpoint on a replica can lag far behind the primary. The commit moves
to inlining global checkpoints with replication requests. When a
replication operation is performed, the primary will send the latest
global checkpoint inline with the replica requests. This keeps the
replicas closer in-sync with the primary.
However, consider a replication request that is not followed by another
replication request for an indefinite period of time. When the replicas
respond to the primary with their local checkpoint, the primary will
advance its global checkpoint. During this indefinite period of time,
the replicas will not be notified of the advanced global
checkpoint. This necessitates a need for another sync. To achieve this,
we perform a global checkpoint sync when a shard falls idle.

Previously, Mustache would call `toString` on the `_ingest.timestamp`
field and return a date format that did not match Elasticsearch's
defaults for date-mapping parsing. The new ZonedDateTime class in Java 8

This commit adds support for a feature flag that enables the usage of this new date format
that has more native behavior.
Fixes#23168.
This new fix can be found in the form of a cluster setting called
`ingest.new_date_format`. By default, in 5.x, the existing behavior
will remain the same. One will set this property to `true` in order to
take advantage of this update for ingest-pipeline convenience.
When installing plugin permissions, we try to set the permissions on all

An important use case for our users is deploying our clients inside of

The plugin cli currently resides inside the elasticsearch jar. This

it does not change anything about what is loaded at runtime. But it will

This leniency was left in after plugin installer refactoring for 2.0

* Replicate write failures
Currently, when a primary write operation fails after generating
a sequence number, the failure is not communicated to the replicas.
Ideally, every operation which generates a sequence number on primary
should be recorded in all replicas.
In this change, a sequence number is associated with write operation
failure. When a failure with an assinged seqence number arrives at a
replica, the failure cause and sequence number is recorded in the translog
and the sequence number is marked as completed via executing `Engine.noOp`
on the replica engine.

After splitting integ tests into cluster configuration and the test
runner task, we still have dependencies of the test runner added as deps
of the cluster. This commit adds dependencies directly to the cluster,
so that the runner can have other dependencies independent of what is
needed for the cluster.
We have some packaging tests where we use a custom jvm.options file. The
flags we use here are barebones, just enough to exercise that using a
custom jvm.options files actually works. Due to this, we are missing a
Log4j flag that prevents Log4j from trying to use JMX. If Log4j tries to
use JMX, it hits a security manager exception and tries to log
this. This attempt to log happens before we've configured
logging. Previously, Elasticsearch was lenient here so this was treated
as harmless and the test could march on. Now, we fail startup if we
detect an attempt to log before logging is configured so this prevents
Elasticsearch from starting if we do not have jvm.options files in place
that prevent these log messages from being written before logging is
being configured. This commit adds jvm.options files in the places need
to prevent this.
These tests were marked as awaits fix due to JNA requiring a version of
glibc greater than or equal to version 2.14. Since we still support
systems that would not have this version, we have released our own JNA

commit removes some await fixes that were added to tests that failed as
a result of this situation.
It can easily happen that we touch a logger before logging is configured

a node will elect itself as master and never form a cluster with another
node.

We currently have the last minor version of the previous major hardcoded
in tests like rolling upgrade. This change programatically finds this
during gradle initialization by parsing versions from Version.java.
These tests were disabled due to an issue in Netty which has since been
resolved and integrated into Elasticsearch.

The current rest backcompat tests, which run against a mixed cluster of
5.x and 6.0 nodes, depend on snapshot builds of 5.x. However, this has
the potential for inconsistency that results in CI failures, and happens
quite often, whenever some backcompat logic is added to 5.x, but the bwc
test on master fails because the 5.x code has not yet been published as
a snapshot.
This change creates a git clone of the 5.x branch,
builds the zip distribution, and ties that into gradle substitutions for
the 5.x version.
We currently use POSIX exit codes in all of our CLIs. However, posix
only suggests these exit codes are standard across tools. It does not
prescribe particular uses for codes outside of that range. This commit
adds 2 exit codes specific to plugin installation to make distinguishing
an incorrectly built plugin and a plugin already existing easier.

This commit catches the underlying failure when trying to list plugin
information when a plugin is incompatible with the current version of
elasticsearch. This could happen when elasticsearch is upgraded but old
plugins still exist. With this change, all plugins will be output,
instead of failing at the first out of date plugin.

This commit marks the EvilJNANativesTests as awaiting fixes due to these
tests failing on platforms that do not provide at least version 2.14 of
glibc.
This commit adds a system property that enables end-users to explicitly
enforce the bootstrap checks, independently of the binding of the
transport protocol. This can be useful for single-node production
systems that do not bind the transport protocol (and thus the bootstrap
checks would not be enforced).

Throw error when skip or do sections are malformed, such as they don't start with the proper token (START_OBJECT). That signals bad indentation, which would be ignored otherwise. Thanks (or due to) our pull parsing code, we were still able to properly parse the sections, yet other runners weren't able to.

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.
* Make document write requests immutable
Previously, write requests were mutated at the
transport level to update request version, version type
and sequence no before replication.
Now that all write requests go through the shard bulk
transport action, we can use the primary response stored
in item level bulk requests to pass the updated version,
seqence no. to replicas.

* minor cleanup
* Add bwc test to ensure correct index version propagates to replica
* Fix bwc for propagating write operation versions
* Add assertion on replica request version type
* fix tests using internal version type for replica op
* Fix assertions to assert version type in replica and recovery

In the packaging tests we make some requests to Elasticsearch as part of
the tests. These requests were not setting the content-type header. This
commit addresses this.
In the packaging tests we make some requests to Elasticsearch as part of

commit addresses this.
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.

These images have been rebuilt to be preloaded with java 8 installed.
This change re-enables the systems. It also removes some redundancy in
the rpm checks I found while testing the new images, and fixes a
potential issue with generated resources in plugins where a stale dir
can cause junk to get into the distribution.
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).
Today either all nodes in the cluster connect to remote clusters of only nodes
that have remote clusters configured in their node config. To allow global remote
cluster configuration but restrict connections to a set of nodes in the cluster
this change adds a new setting `search.remote.connect` (defaults to `true`) to allow
to disable remote cluster connections on a per node basis.
This commit upgrades the checkstyle configuration from version 5.9 to
version 7.5, the latest version as of today. The main enhancement
obtained via this upgrade is better detection of redundant modifiers.

When a primary is relocated from an old node to a new node, it can have
ops in its translog that do not have a sequence number assigned. When a
file-based recovery is started, this can lead to skipping these ops when
replaying the translog due to a bug in the recovery logic. This commit
addresses this bug and adds a test in the BWC tests.

Today if a user invokes the remove plugin command without specifying the
name of a plugin to remove, we arrive at a null pointer exception. This
commit adds logic to cleanly handle this situation and provide clear
feedback to the user.

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
Currently, stored scripts use a namespace of (lang, id) to be put, get, deleted, and executed. This is not necessary since the lang is stored with the stored script. A user should only have to specify an id to use a stored script. This change makes that possible while keeping backwards compatibility with the previous namespace of (lang, id). Anywhere the previous namespace is used will log deprecation warnings.
The new behavior is the following:
When a user specifies a stored script, that script will be stored under both the new namespace and old namespace.
Take for example script 'A' with lang 'L0' and data 'D0'. If we add script 'A' to the empty set, the scripts map will be ["A" -- D0, "A#L0" -- D0]. If a script 'A' with lang 'L1' and data 'D1' is then added, the scripts map will be ["A" -- D1, "A#L1" -- D1, "A#L0" -- D0].
When a user deletes a stored script, that script will be deleted from both the new namespace (if it exists) and the old namespace.
Take for example a scripts map with {"A" -- D1, "A#L1" -- D1, "A#L0" -- D0}. If a script is removed specified by an id 'A' and lang null then the scripts map will be {"A#L0" -- D0}. To remove the final script, the deprecated namespace must be used, so an id 'A' and lang 'L0' would need to be specified.
When a user gets/executes a stored script, if the new namespace is used then the script will be retrieved/executed using only 'id', and if the old namespace is used then the script will be retrieved/executed using 'id' and 'lang'
This commit introduces sequence-number-based recovery. When a replica
has fallen out of sync, rather than performing a file-based recovery we
first attempt to replay operations since the last local checkpoint on
the replica. To do this, at the start of recovery the replica tells the
primary what its local checkpoint is. The primary will then wait for all
operations between that local checkpoint and the current maximum
sequence number to complete; this is to ensure that there are no gaps in
the operations that will be replayed from the primary to the
replica. This is a best-effort attempt as we currently have no
guarantees on the primary that these operations will be available; if we
are not able to replay all operations in the desired range, we just
fallback to file-based recovery. Later work will strengthen the
guarantees.

This is related to #22116. URLRepository requires SocketPermission
connect. This commit introduces a new module called "repository-url"
where URLRepository will reside. With the new module, permissions can
be removed from core.
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
