It can easily happen that we touch a logger before logging is configured
due to chains of static intializers and other such scenarios. This
commit adds detection for this mechanism that will fail startup if we
touch a logger before logging is configured. This is a bug that will
cause builds to fail.

This is related to #23893. This commit allows users to use wilcards for
cluster names when executing a cross cluster search.
So instead of defining every cluster such as:
GET one:*,two:*,three:*/_search
A user could just search:
GET *:*/_search
As ":" characters are currently allowed in index names, if the text
up to the first ":" does not match a defined cluster name, the entire
string is treated as an index name.
All our actions that are invoked from rest actions have corresponding
transport actions. This adds the transport action for RestRemoteClusterInfoAction
for consistency.

attempting to set the permissions.
This commit renames the random ASCII helper methods in ESTestCase. This

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

This commit catches the underlying failure when trying to list 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

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).

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

seqence no. to replicas.

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.

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

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

addresses this bug and adds a test in the BWC tests.

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
For certain situations, end-users need the base path for Elasticsearch
logs. Exposing this as a property is better than hard-coding the path
into the logging configuration file as otherwise the logging
configuration file could easily diverge from the Elasticsearch
configuration file. Additionally, Elasticsearch will only have
permissions to write to the log directory configured in the
Elasticsearch configuration file. This commit adds a property that
exposes this base path.
One use-case for this is configuring a rollover strategy to retain logs
for a certain period of time. As such, we add an example of this to the
documentation.
Additionally, we expose the property es.logs.cluster_name as this is
used as the name of the log files in the default configuration.
Finally, we expose es.logs.node_name in cases where node.name is
explicitly set in case users want to include the node name as part of
the name of the log files.

This commit removes a logging test that is now obsolete. This test was
added when we included a forked version of some Log4j 2 classes to

that time, the forked versions were removed, and this test should have
been removed with it.
* Fix Translog.Delete serialization for sequence numbers
Translog.Delete used `.writeVLong` instead of `.writeLong` for the sequence
number and primary term (and their respective "read" variants). This could lead
to issues where a 5.x node sent a translog operation with a negative sequence
number (-2 for unassigned seq no) that tripped an assertion serializing a
negative number and causing ES to exit.
Adds a unit test for serialization and a mixed-cluster REST test, since that was
how this was originally caught.
* Use more realistic values for random seqNum and primary term
* Add comment with TODO for removal in 7.0
* Change comment into an assert
Instead of `search.remote.seeds.${clustername}` we now specify the seeds as:
`search.remote.${clustername}.seeds` which is a real list setting compared to an unvalidated
group setting before.
`ToXContentObject` extends `ToXContent` without adding new methods to it, while allowing to mark classes that output complete xcontent objects to distinguish them from classes that require starting and ending an anonymous object externally.
Ideally ToXContent would be renamed to ToXContentFragment, but that would be a huge change in our codebase, hence we simply document the fact that toXContent outputs fragments with no guarantees that the output is valid per se without an external ancestor.

this commit adds full support for proxy nodes on the search layer.
This allows to connection only to a small set of nodes on a remote cluster
to exectue the search. The nodes will proxy the request to the correct node in the
cluster while the coordinting node doesn't need to be connected to the target node.
This change is the first towards providing the ability to store
sensitive settings in elasticsearch. It adds the
`elasticsearch-keystore` tool, which allows managing a java keystore.
The keystore is loaded upon node startup in Elasticsearch, and used by
the Setting infrastructure when a setting is configured as secure.
There are a lot of caveats to this PR. The most important is it only
provides the tool and setting infrastructure for secure strings. It does
not yet provide for keystore passwords, keypairs, certificates, or even
convert any existing string settings to secure string settings. Those
will all come in follow up PRs. But this PR was already too big, so this
at least gets a basic version of the infrastructure in.
The two main things to look at. The first is the `SecureSetting` class,
which extends `Setting`, but removes the assumption for the raw value of the
setting to be a string. SecureSetting provides, for now, a single
helper, `stringSetting()` to create a SecureSetting which will return a
SecureString (which is like String, but is closeable, so that the
underlying character array can be cleared). The second is the
`KeyStoreWrapper` class, which wraps the java `KeyStore` to provide a
simpler api (we do not need the entire keystore api) and also extend
the serialized format to add metadata needed for loading the keystore
with no assumptions about keystore type (so that we can change this in
the future) as well as whether the keystore has a password (so that we
can know whether prompting is necessary when we add support for keystore
passwords).
* Remove a checked exception, replacing it with `ParsingException`.
* Remove all Parser classes for the yaml sections, replacing them with static methods.

I did not rewrite the parsers using `ObjectParser` because I don't think it is worth it right now.
Today if an older version of a plugin exists, we fail to notify the user
with a helpful error message. This happens because during plugin
verification, we attempt to read the plugin descriptors for all existing
plugins. When an older version of a plugin is sitting on disk, we will
attempt to read this old plugin descriptor and fail due to a version
mismatch. This leads to an unhelpful error message. Instead, we should
check for existence of the plugin as part of the verification phase, but
before attempting to read plugin descriptors for existing plugins. This
enables us to provide a helpful error message to the user.

* Internal: Refactor SettingCommand into EnvironmentAwareCommand
This change renames and changes the behavior of SettingCommand to have
its primary method take in a fully initialized Environment for
elasticsearch instead of just a map of settings. All of the subclasses
of SettingCommand already did this at some point, so this just removes
duplication.
We are currenlty checking that no deprecation warnings are emitted in our query tests. That can be moved to ESTestCase (disabled in ESIntegTestCase) as it allows us to easily catch where our tests use deprecated features and assert on the expected warnings.
Sequence BWC logic consists of two elements:
1) Wire level BWC using stream versions.
2) A changed to the global checkpoint maintenance semantics.
For the sequence number infra to work with a mixed version clusters, we have to consider situation where the primary is on an old node and replicas are on new ones (i.e., the replicas will receive operations without seq#) and also the reverse (i.e., the primary sends operations to a replica but the replica can't process the seq# and respond with local checkpoint). An new primary with an old replica is a rare because we do not allow a replica to recover from a new primary. However, it can occur if the old primary failed and a new replica was promoted or during primary relocation where the source primary is treated as a replica until the master starts the target.
1) Old Primary & New Replica - this case is easy as is taken care of by the wire level BWC. All incoming requests will have their seq# set to `UNASSIGNED_SEQ_NO`, which doesn't confuse the local checkpoint logic (keeping it at `NO_OPS_PERFORMED`)
2) New Primary & Old replica - this one is trickier as the global checkpoint service currently takes all in sync replicas into consideration for the global checkpoint calculation. In order to deal with old replicas, we change the semantics to say all *new node* in sync replicas. That means the replicas on old nodes don't count for the global checkpointing. In this state the seq# infra is not fully operational (you can't search on it, because copies may miss it) but it is maintained on shards that can support it. The old replicas will have to go through a file based recovery at some point and will get the seq# information at that point. There is still an edge case where a new primary fails and an old replica takes over. I'lll discuss this one with @ywelsch as I prefer to avoid it completely.
This PR also re-enables the BWC tests which were disabled. As such it had to fix any BWC issue that had crept in. Most notably an issue with the removal of the `timestamp` field in #21670.
The commit also includes a fix for the default value of the seq number field in replicated write requests (it was 0 but should be -2), that surface some other minor bugs which are fixed as well.
Last - I added some debugging tools like more sane node names and forcing replication request to implement a `toString`
Today in the codebase we refer to seccomp everywhere instead of system

Our query DSL supports empty queries (`{}`), which have a different meaning depending on the query that holds it, either ignored, match_all or match_none. We deprecated the support for empty queries in 5.0, where we log a deprecation warning wherever they are used.
The way we supported it once we moved query parsing to the coordinating node was having an Optional<QueryBuilder> return type in all of our parse methods (called fromXContent). See #17624. The central place for this was QueryParseContext#parseInnerQueryBuilder. We can now remove all the optional return types and simply throw an exception whenever an empty query is found.
Action filters currently have the ability to filter both the request and
response. But the response side was not actually used. This change
removes support for filtering responses with action filters.
We don't use the test infra nor do we run the tests. They might all be
entirely out of date. We also have a different BWC test infra in-place.
This change removes all of the legacy infra.
For the record, I also had to remove the geo-hash cell and geo-distance range
queries to make the code compile. These queries already throw an exception in
all cases with 5.x indices, so that does not hurt any more.
I also had to rename all 2.x bwc indices from `index-${version}` to
`unsupported-${version}` to make `OldIndexBackwardCompatibilityIT`
happy.

There is not yet a BWC layer in sequence numbers. This commit sets the
BWC version to 6.0.0 for the BWC and rolling upgrade tests until this
BWC layer is built.
Adds a version constant for it, bwc indices, and a vagrant upgrade-from
version. Also bumps the "upgrade from" version for the backwards-5.0
test and adds `skip`s for tests that don't fail against 5.0 so we skip
them during the backwards testing.
Finally, this skips the "Shrink index via API" test because it fails
consistently for me. Inconsistently for CI, but consistently for me.
I'll work on making it consistent tomorrow.
In #21348 the command executed to run the packaging tests has been changed to "sudo -E bats ...", forcing all environment variables from the vagrant user to be passed to the `sudo` command. This breaks a test on opensuse-13 (the one where it checks that elasticsearch cannot be started when `java` is not found) because all the PATH from the user is passed to the sudo command.
This commit restores the previous behavior while allowing only necessary testing environment variables to be passed using a /etc/sudoers.d file.
This changes adds a test discovery (which internally uses the existing
mock zenping by default). Having the mock the test framework selects be a discovery
greatly simplifies discovery setup (no more weird callback to a Node
method).
Today when a node starts, we create dynamic socket permissions based on
the configured HTTP ports and transport ports. If no ports are
configured, we use the default port ranges. When a tribe node starts, a
tribe node creates an internal node client for connecting to each remote
cluster. If neither an explicit HTTP port nor transport ports were
specified, the default port ranges are large enough for the tribe node
and its internal node clients. If an explicit HTTP port or transport
port was specified for the tribe node, then socket permissions for those
ports will be created, but not for the internal node clients. Whether
the internal node clients have explicit ports specified, or attempt to
bind within the default range, socket permissions for these will not
have been created and the internal node clients will hit a permissions
issue when attempting to bind. This commit addresses this issue by also
accounting for tribe nodes when creating the dynamic socket
permissions. Additionally, we add our first real integration test for
tribe nodes.

This commit changes the current :elactisearch:qa:vagrant build file and transforms it into a Gradle plugin in order to reuse it in other projects.
Most of the code from the build.gradle file has been moved into the VagrantTestPlugin class. To avoid duplicated VMs when running vagrant tests, the Gradle plugin sets the following environment variables before running vagrant commands:
VAGRANT_CWD: absolute path to the folder that contains the Vagrantfile
VAGRANT_PROJECT_DIR: absolute path to the Gradle project that use the VagrantTestPlugin
The VAGRANT_PROJECT_DIR is used to share project folders and files with the vagrant VM. These folders and files are exported when running the task `gradle vagrantSetUp` which:
- collects all project archives dependencies and copies them into `${project.buildDir}/bats/archives`
- copy all project bats testing files from 'src/test/resources/packaging/tests' into `${project.buildDir}/bats/tests`
- copy all project bats utils files from 'src/test/resources/packaging/utils' into `${project.buildDir}/bats/utils`
It is also possible to inherit and grab the archives/tests/utils files from project dependencies using the plugin configuration:
apply plugin: 'elasticsearch.vagrant'
esvagrant {
inheritTestUtils true|false
inheritTestArchives true|false
inheritTests true|false
}
dependencies {
// Inherit Bats test utils from :qa:vagrant project
bats project(path: ':qa:vagrant', configuration: 'bats')
}
The folders `${project.buildDir}/bats/archives`, `${project.buildDir}/bats/tests` and `${project.buildDir}/bats/utils` are then exported to the vagrant VMs and mapped to the BATS_ARCHIVES, BATS_TESTS and BATS_UTILS environnement variables.
The following Gradle tasks have also be renamed:
* gradle vagrantSetUp
This task copies all the necessary files to the project build directory (was `prepareTestRoot`)
* gradle vagrantSmokeTest
This task starts the VMs and echoes a "Hello world" within each VM (was: `smokeTest`)
On some systems these utilities are in /usr/lib/systemd/systemd-sysctl
and /usr/sbin/sysctl, and on others the /usr is dropped. This commit
accounts for that fact.
Our docs claim that we set vm.max_map_count automatically. This is not
quite the case. The story is that on SysV init we set vm.max_map_count
each time the service starts, which is good. On systemd, we create a
sysctl.d conf file that sets vm.map_max_count, but this is only
meaningful if the system is rebooted after package install. This commit
modifies the post-install script so that we run systemd-sysctl so that
the vm.max_map_count change occurs after package install without a
reboot.

At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.
Today if you start Elasticsearch with the status logger configured to
the warn level, or use a transport client with the default status logger
level, you will see warn messages about deprecation loggers being
created with different message factories and that formatting might be
broken. This happens because the deprecation logger is constructed using
the message factory from its parent, an artifact leftover from the first
Log4j 2 implementation that used a custom message factory. When that
custom message factory was removed, this constructor invocation should
have been changed to not explicitly use the message factory from the
parent. This commit fixes this invocation. However, we also had some
status checking to all tests to ensure that there are no warn status log
messages that might indicate a configuration problem with Log4j 2. These
assertions blow up badly without the fix for the deprecation logger
construction, and also caught a misconfiguration in one of the logging
tests.

Plugins: Remove pluggability of ZenPing
ZenPing is the part of zen discovery which knows how to ping nodes.
There is only one alternative implementation, which is just for testing.
This change removes the ability to add custom zen pings, and instead
hooks in the MockZenPing for tests through an overridden method in
MockNode. This also folds in the ZenPingService (which was really just a
single method) into ZenDiscovery, and removes the idea of having
multiple ZenPing instances. Finally, this was the last usage of the
ExtensionPoint classes, so that is also removed here.
When installing a plugin when the plugins directory does not exist, the
install plugin command outputs a line saying that it is creating this
directory. The packaging tests for the archive distributions accounted
for this including an assertion that this line was output. The packages
have since been updated to include an empty plugins folder, so this line
will no longer be output. This commit removes this stale assertion from
the packaging tests.

Today when installing Elasticsearch from an archive distribution (tar.gz
or zip), an empty plugins folder is not included. This means that if you
install Elasticsearch and immediately run elasticsearch-plugin list, you
will receive an error message about the plugins directory missing. While
the plugins directory would be created when starting Elasticsearch for
the first time, it would be better to just include an empty plugins
directory in the archive distributions. This commit makes this the
case. Note that the package distributions already include an empty
plugins folder.

Vagrant tests use a static list of dependencies to upgrade from
and we weren't including 5.0.0 deps in that list. Also when the
list was incorrect we weren't sorting the "current" list so it
was difficult to read.
Also adds 2.4.1 to the list but *doesn't* add 5.0.0 because we
still can't resolve it yet. We still only print an error when
the list is wrong but don't abort the build. We'll abort the build
once we've fixed resolution for 5.0.0 and we can re-add it.
We are upgrading from out of date versions in our tests right now and we
can't fix that because the current versions to upgrade from aren't in
maven central. We'll resolve the resolution issue soon, but for now
let's get the build green.
Since with j`ava-1.8.0-openjdk-1.8.0.111-1.b15.el7_2.x86_64`, the OpenJDK packaged for CentOS and OEL override the default value (`false`) for the JVM option `AssumeMP` and force it to `true` (see [this patch](https://git.centos.org/blob/rpms!!java-1.8.0-openjdk.git/ab03fcc7a277355a837dd4c8500f8f90201ea353/SOURCES!always_assumemp.patch))
Because it is forced to true by default for these packages, the following warning message is printed to the standard output when the Vagrant box has only 1 CPU:
> OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N
This message will then fail the test introduced in #20422 where we check if no entries have been added to the journal after the service has been started.
This commit restore the default value for the `AssumeMP` option for CentOS and OracleServer.
This commit mutes a check on the output of journalctl after the Elasticsearch's systemd service has been started. It expected no entries in the journal but since OpenJDK build 1.8.0_111-b15 the following warning message is printed:
OpenJDK 64-Bit Server VM warning: If the number of processors is expected to increase from one, then you should configure the number of parallel GC threads appropriately using -XX:ParallelGCThreads=N
`LocalDiscovery` is a discovery implementation that uses static in memory maps to keep track of current live nodes. This is used extensively in our tests in order to speed up cluster formation (i.e., shortcut the 3 second ping period used by `ZenDiscovery` by default). This is sad as that mean that most of the test run using a different discovery semantics than what is used in production. Instead of replacing the entire discovery logic, we can use a similar approach to only shortcut the pinging components.
This change proposes the removal of all non-tcp transport implementations. The
mock transport can be used by default to run tests instead of local transport that has
roughly the same performance compared to TCP or at least not noticeably slower.
This is a master only change, deprecation notice in 5.x will be committed as a
separate change.
Today when parsing a request, Elasticsearch silently ignores incorrect
(including parameters with typos) or unused parameters. This is bad as
it leads to requests having unintended behavior (e.g., if a user hits
the _analyze API and misspell the "tokenizer" then Elasticsearch will
just use the standard analyzer, completely against intentions).
This commit removes lenient URL parameter parsing. The strategy is
simple: when a request is handled and a parameter is touched, we mark it
as such. Before the request is actually executed, we check to ensure
that all parameters have been consumed. If there are remaining
parameters yet to be consumed, we fail the request with a list of the
unconsumed parameters. An exception has to be made for parameters that
format the response (as opposed to controlling the request); for this
case, handlers are able to provide a list of parameters that should be
excluded from tripping the unconsumed parameters check because those
parameters will be used in formatting the response.
Additionally, some inconsistencies between the parameters in the code
and in the docs are corrected.

Today when executing the install plugin command without a plugin id, we
end up throwing an NPE because the plugin id is null yet we just keep

Today when CLI tools are executed, logging statements can intentionally

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.
Today when starting Elasticsearch without a Log4j 2 configuration file,
we end up throwing an array index out of bounds exception. This is

should throw a useful error message to the user. This commit modifies
the Log4j configuration setup to throw a user exception if no Log4j
configuration files are present in the config directory.

BATS upgrade tests fails on master branch because it tries to install 2.x versions to upgrade from instead of 5.x versions. And since #18554 we should only test upgrades from 5.0.0-alpha4 versions.
This commit changes the vagrant tests so that it tries to list all the previous releases from version N-1. If nothing is found, it will fetch the current version and will run the upgrade tests with it. It works nicely with the current master 6.0.0-alpha1-SNAPSHOT. Once 5.0.0 is released it should run the test with it.
When uninstalling or upgrading elasticsearch using the RPM package some empty directories remain on the filesystem:
/usr/share/elasticsearch/bin
/usr/share/elasticsearch/lib
/usr/share/elasticsearch/modules
/usr/share/elasticsearch/modules/foo
Having empty directories in modules can prevent elasticsearch to start after an upgrade: the plugins service expects to find a plugin-descriptor.properties file in every sub directory of modules.
This PR cleans things a bit so that these empty directories are removed on upgrade/removal like it was in 2.x.
The Log4j shutdown hack test tests that a hack we have in place to
workaround a bug in Log4j during shutdown is effective. Log4j can use
JMX to control logging levels, but we disable this through the use of a
system property log4j2.disable.jmx (mainly because there is no need for
this feature, but it also means granting additional security
permissions). The bug in Log4j is that during shutdown, it neglects to
check whether or not its usage of JMX is disable and so it attempts to
unregister management beans, leading to a permissions violation. The
test works by attempting to shutdown Log4j and thus triggering the bad
code path. With the Log4j hack in place, we have introduced jar hell so
that its our code running instead of code from the Log4j jar. Our code
correctly checks that the usage of JMX is disabled and thus does not
trip on a permissions violation. The test was a little complicated in
that it attempted to just grant the minimal permissions needed for Log4j
to do its thing, but this can sometimes lead to other unwanted
permissions violations because the permissions put in place are more
restrictive necessary. This commit simplifies this situation by
rewriting the test to only deny Log4j the sole permission needed to
trigger the bug.

When upgrading elasticsearch using the RPM package, the scripts directory is removed if it's empty but it won't be recreated by the upgraded package. But after that the service won't start because the scripts dir is missing.
Today when setting the logging level via the command-line or an API
call, the expectation is that the logging level should trickle down the
hiearchy to descendant loggers. However, this is not necessarily the
case. For example, if loggers x and x.y are already configured then
setting the logging level on x will not descend to x.y. This is because
the logging config for x.y has already been forked from the logging
config for x. Therefore, we must explicitly descend the hierarchy when
setting the logging level and that is what this commit does.

This commit introduces a new plugin for file-based unicast hosts
discovery. This allows specifying the unicast hosts participating
in discovery through a `unicast_hosts.txt` file located in the
`config/discovery-file` directory. The plugin will use the hosts
specified in this file as the set of hosts to ping during discovery.
The format of the `unicast_hosts.txt` file is to have one host/port
entry per line. The hosts file is read and parsed every time
discovery makes ping requests, thus a new version of the file that
is published to the config directory will automatically be picked
up.
Closes#20323
Today we add a prefix when logging within Elasticsearch. This prefix
contains the node name, and index and shard-level components if
appropriate.
Due to some implementation details with Log4j 2 , this does not work for
integration tests; instead what we see is the node name for the last
node to startup. The implementation detail here is that Log4j 2 there is
only one logger for a name, message factory pair, and the key derived
from the message factory is the class name of the message factory. So,
when the last node starts up and starts setting prefixes on its message
factories, it will impact the loggers for the other nodes.
Additionally, the prefixes are lost when logging an exception. This is
due to another implementation detail in Log4j 2. Namely, since we log
exceptions using a parameterized message, Log4j 2 decides that that
means that we do not want to use the message factory that we have
provided (the prefix message factory) and so logs the exception without
the prefix.
This commit fixes both of these issues.

This commit adds a -q/--quiet option to Elasticsearch so that it does not log anything in the console and closes stdout & stderr streams. This is useful for SystemD to avoid duplicate logs in both journalctl and /var/log/elasticsearch/elasticsearch.log while still allows the JVM to print error messages in stdout/stderr if needed.

The plugin command now displays the version of the plugin, which is
compared to a string without the version. This removes the version from
the string.
The evil logger tests rely on external configuration. This configuration
is shared between these tests which means that changing the
configuration for one test can cause an unrelated test to fail. In
particular, removing the appenders on the root logger so that inherited
loggers in one test do not have a console and file appender by default
breaks tests that were expecting the root logger to have these
appenders. This commit separates these configs so that these tests are
not subject to this problem.
Log4j has a bug where on shutdown it ignores that JMX might be disabled;
since it does not respect this on shutdown, it proceeds to attempt to
access JMX leading to a security exception that should have otherwise
not occurred had it respected that JMX is disabled. This commit
intentionally introduces jar hell with the Server class to work around
this bug until a fix is released.

Previously we would disable console logging in certain circumstances

Previous versions of Elasticsearch permitted unquoted JSON field names even though this is against the JSON spec.

By default, when an exception causes the JVM to terminate, the stack
trace is printed. In the case of failing bootstrap checks, this stack
trace is useless to the user, and might even distract them from seeing
that the bootstrap checks failed for reasons under their control. With
this commit, we cause the stack trace for a failing bootstrap check to
be truncated.
We also modify some methods to not declare that they throw the top level
checked exception type Exception, but instead explicitly declare the
exceptions that they throw. These exceptions are caught and wrapped in a
BootstrapException so that we can percolate only two exception types out
of Bootstrap#init as checked exception, BootstrapException and
NodeValidationException.

Netty 3 and Netty 4 so that the randomization is choosing between Netty

scripts (<https://www.elastic.co/guide/en/elasticsearch/reference/master/modules-scripting-using.html#prefer-params>)

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

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

This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared

**the** rest tests.
This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the

This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
* rethrow script compilation exceptions into ingest configuration exceptions
* update readProcessor to rethrow any exception as an ElasticsearchException
Remove `ParseField` constants used for names where there are no deprecated
names and just use the `String` version of the registration method instead.
This is step 2 in cleaning up the plugin interface for extending
search time actions. Aggregations are next.
This is breaking for plugins because those that register a new query should
now implement `SearchPlugin` rather than `onModule(SearchModule)`.
We throw IOException, which is the exception that is going to be thrown in 99% of the cases. A more generic exception can happen, and if it is a runtime one we just let it bubble up as is, otherwise we wrap it into runtime one so that we don't require to catch Exception everywhere, which seems odd.
Also adjusted javadocs for all performRequest methods
The new method accepts the usual parameters (method, endpoint, params, entity and headers) plus a response listener and an async response consumer. Shortcut methods are also added that don't require params, entity and the async response consumer optional.
There are a few relevant api changes as a consequence of the move to async client that affect sync methods:
- Response doesn't implement Closeable anymore, responses don't need to be closed
- performRequest throws Exception rather than just IOException, as that is the the exception that we get from the FutureCallback#failed method in the async http client
- ssl configuration is a bit simpler, one only needs to call setSSLStrategy from a custom HttpClientConfigCallback, that doesn't end up overridng any other default around connection pooling (it used to happen with the sync client and make ssl configuration more complex)
