* remove left-over comment
* make sure of the property for plugins
* skip installing modules if these exist in the distribution
* Log the distrbution being ran
* Don't allow running with integ-tests-zip passed externally
* top level x-pack/qa can't run with oss distro
* Add support for matching objects in lists
Makes it possible to have a key that points to a list and assert that a
certain object is present in the list. All keys have to be present and
values have to match. The objects in the source list may have additional
fields.
example:
```
match: { 'nodes.$master.plugins': { name: ingest-attachment } }
```
* Update plugin and module tests to work with other distributions
Some of the tests expected that the integration tests will always be ran
with the `integ-test-zip` distribution so that there will be no other
plugins loaded.
With this change, we check for the presence of the plugin without
assuming exclusivity.
* Allow modules to run on other distros as well
To match the behavior of tets.distributions
* Add and use a new `contains` assertion
Replaces the previus changes that caused `match` to do a partial match.
* Implement PR review comments
Introduces support for multiple host providers, which allows the settings based hosts resolver to be
treated just as any other UnicastHostsProvider. Also introduces the notion of a HostsResolver so
that plugins such as FileBasedDiscovery do not need to create their own thread pool for resolving
hosts, making it easier to add new similar kind of plugins.
With #20695 we removed local transport and there is just TransportAddress now. The
UnicastHostsProvider currently returns DiscoveryNode instances, where, during pinging, we're
actually only making use of the TransportAddress to establish a first connection to the possible new
node. To simplify the interface, we can just return a list of transport addresses instead, which
means that it's not necessary anymore to create fake node objects in each plugin just to return the
address information.
Adds the ability to reread and decrypt the local node keystore.
Commonly, the contents of the keystore, backing the `SecureSettings`,
are not retrievable except during node initialization. This changes that
by adding a new API which broadcasts a password to every node. The
password is used to decrypt the local keystore and use it to populate
a `Settings` object that is passes to all the plugins implementing the
`ReloadablePlugin` interface. The plugin is then responsible to do
whatever "reload" means in his case. When the `reload`handler returns,
the keystore is closed and its contents are no longer retrievable.
Password is never stored persistently on any node.
Plugins that have been moded in this commit are: `repository-azure`,
`repository-s3`, `repository-gcs` and `discovery-ec2`.
This commit adds a new QA sub project to the discovery-ec2 plugin.
This project uses a fixture to test the plugin using a multi-node cluster.
Once all nodes are started, the nodes transport addresses are written
in a file that is later read by the fixture.
Some source files seem to have the execute bit (a+x) set, which doesn't
really seem to hurt but is a bit odd. This change removes those, making
the permissions similar to other source files in the repository.
As we have factored Elasticsearch into smaller libraries, we have ended
up in a situation that some of the dependencies of Elasticsearch are not
available to code that depends on these smaller libraries but not server
Elasticsearch. This is a good thing, this was one of the goals of
separating Elasticsearch into smaller libraries, to shed some of the
dependencies from other components of the system. However, this now
means that simple utility methods from Lucene that we rely on are no
longer available everywhere. This commit copies IOUtils (with some small
formatting changes for our codebase) into the fold so that other
components of the system can rely on these methods where they no longer
depend on Lucene.
This one is interesting. The third party audit task runs inside the
Gradle JVM. This means that if Gradle is started on JDK 8, the third
party audit tasks will fail as a result of the changes to support
building Elasticsearch with the JDK 9 compiler. This commit reverts the
third party audit changes to support running this task when Gradle is
started with JDK 8.
Relates #28256
This commit modifies the build to require JDK 9 for
compilation. Henceforth, we will compile with a JDK 9 compiler targeting
JDK 8 as the class file format. Optionally, RUNTIME_JAVA_HOME can be set
as the runtime JDK used for running tests. To enable this change, we
separate the meaning of the compiler Java home versus the runtime Java
home. If the runtime Java home is not set (via RUNTIME_JAVA_HOME) then
we fallback to using JAVA_HOME as the runtime Java home. This enables:
- developers only have to set one Java home (JAVA_HOME)
- developers can set an optional Java home (RUNTIME_JAVA_HOME) to test
on the minimum supported runtime
- we can test compiling with JDK 9 running on JDK 8 and compiling with
JDK 9 running on JDK 9 in CI
TestZenDiscovery is used to allow discovery based on in memory structures. This isn't a relevant for the cloud providers tests (but isn't a problem at the moment either)
The AWS SDK has a transitive dependency on Jackson Databind. While the
AWS SDK was recently upgraded, the Jackson Databind dependency was not
pulled along with it to the version that the AWS SDK depends on. This
commit upgrades the dependencies for discovery-ec2 and repository-s3
plugins to match versions on the AWS SDK transitive dependencies.

Today we return a `String[]` that requires copying values for every
access. Yet, we already store the setting as a list so we can also directly
return the unmodifiable list directly. This makes list / array access in settings
a much cheaper operation especially if lists are large.
Today we represent each value of a list setting with it's own dedicated key
that ends with the index of the value in the list. Aside of the obvious
weirdness this has several issues especially if lists are massive since it
causes massive runtime penalties when validating settings. Like a list of 100k
words will literally cause a create index call to timeout and in-turn massive
slowdown on all subsequent validations runs.
With this change we use a simple string list to represent the list. This change
also forbids to add a settings that ends with a .0 which was internally used to
detect a list setting. Once this has been rolled out for an entire major
version all the internal .0 handling can be removed since all settings will be
converted.

We use group settings historically instead of using a prefix setting which is more restrictive and type safe. The majority of the usecases needs to access a key, value map based on the _leave node_ of the setting ie. the setting `index.tag.*` might be used to tag an index with `index.tag.test=42` and `index.tag.staging=12` which then would be turned into a `{"test": 42, "staging": 12}` map. The group settings would always use `Settings#getAsMap` which is loosing type information and uses internal representation of the settings. Using prefix settings allows now to access such a method type-safe and natively.
This commit contains:
* update AWS SDK for ECS Task IAM support
* ignore dependencies not essential to `discovery-ec2`:
* jmespath seems to be used for `waiters`
* amazon ion is a protocol not used by EC2 or IAM
With Gradle 4.1 and newer JDK versions, we can finally invoke Gradle directly using a JDK9 JAVA_HOME without requiring a JDK8 to "bootstrap" the build. As the thirdPartyAudit task runs within the JVM that Gradle runs in, it needs to be adapted now to be JDK9 aware.
This commit also changes the `JavaCompile` tasks to only fork if necessary (i.e. when Gradle's JVM and JAVA_HOME's JVM differ).
This commit makes the use of the global network settings explicit instead
of implicit within NetworkService. It cleans up several places where we fall
back to the global settings while we should have used tcp or http ones.
In addition this change also removes unnecessary settings classes
Those plugins don't replace the discovery logic but rather only provide a custom unicast host provider for their respective platforms. in 5.1 we introduced the `discovery.zen.hosts_provider` setting to better reflect it. This PR removes BWC code in those plugins as it is not needed anymore
Fixes#24543
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.
When constructing an array list, if we know the size of the list in
advance (because we are adding objects to it derived from another list),
we should size the array list to the appropriate capacity in advance (to
avoid resizing allocations). This commit does this in various places.

Changes the scope of the AllocationService dependency injection hack so that it is at least contained to the AllocationService and does not leak into the Discovery world.
Separates cluster state publishing from applying cluster states:
- ClusterService is split into two classes MasterService and ClusterApplierService. MasterService has the responsibility to calculate cluster state updates for actions that want to change the cluster state (create index, update shard routing table, etc.). ClusterApplierService has the responsibility to apply cluster states that have been successfully published and invokes the cluster state appliers and listeners.
- ClusterApplierService keeps track of the last applied state, but MasterService is stateless and uses the last cluster state that is provided by the discovery module to calculate the next prospective state. The ClusterService class is still kept around, which now just delegates actions to ClusterApplierService and MasterService.
- The discovery implementation is now responsible for managing the last cluster state that is used by the consensus layer and the master service. It also exposes the initial cluster state which is used by the ClusterApplierService. The discovery implementation is also responsible for adding the right cluster-level blocks to the initial state.
- NoneDiscovery has been renamed to TribeDiscovery as it is exclusively used by TribeService. It adds the tribe blocks to the initial state.
- ZenDiscovery is synchronized on state changes to the last cluster state that is used by the consensus layer and the master service, and does not submit cluster state update tasks anymore to make changes to the disco state (except when becoming master).
Control flow for cluster state updates is now as follows:
- State updates are sent to MasterService
- MasterService gets the latest committed cluster state from the discovery implementation and calculates the next cluster state to publish
- MasterService submits the new prospective cluster state to the discovery implementation for publishing
- Discovery implementation publishes cluster states to all nodes and, once the state is committed, asks the ClusterApplierService to apply the newly committed state.
- ClusterApplierService applies state to local node.
This commit removes the deprecated cloud.aws.* settings. It also removes
backcompat for specifying `discovery.type: ec2`, and unused aws signer
code which was removed in a previous PR.
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`.
closes#20240
This commit removes the "legacy" feature of secure settings, which setup
a parallel setting that was a fallback in the insecure
elasticsearch.yml. This was previously used to allow the new secure
setting name to be that of the old setting name, but is now not in use
due to other refactorings. It is much cleaner to just have all secure
settings use new setting names. If in the future we want to reuse the
previous setting name, once support for the insecure settings have been
removed, we can then rename the secure setting. This also adds a test
for the behavior.
This change adds secure settings for access/secret keys and proxy
username/password to ec2 discovery. It adds the new settings with the
prefix `discovery.ec2`, copies other relevant ec2 client settings to the
same prefix, and deprecates all other settings (`cloud.aws.*` and
`cloud.aws.ec2.*`). Note that this is simpler than the client configs
in repository-s3 because discovery is only initialized once for the
entire node, so there is no reason to complicate the configuration with
the ability to have multiple sets of client settings.

The warning header used by Elasticsearch for delivering deprecation
warnings has a specific format (RFC 7234, section 5.5). The format
specifies that the warning header should be of the form
warn-code warn-agent warn-text [warn-date]
Here, the warn-code is a three-digit code which communicates various
meanings. The warn-agent is a string used to identify the source of the
warning (either a host:port combination, or some other identifier). The
warn-text is quoted string which conveys the semantic meaning of the
warning. The warn-date is an optional quoted date that can be in a few
different formats.
This commit corrects the warning header within Elasticsearch to follow
this specification. We use the warn-code 299 which means a
"miscellaneous persistent warning." For the warn-agent, we use the
version of Elasticsearch that produced the warning. The warn-text is
unchanged from what we deliver today, but is wrapped in quotes as
specified (this is important as a problem that exists today is that
multiple warnings can not be split by comma to obtain the individual
warnings as the warnings might themselves contain commas). For the
warn-date, we use the RFC 1123 format.

This is related to #22116. This commit adds calls that require
SocketPermission connect to forbidden APIs.
The following calls are now forbidden:
- java.net.URL#openStream()
- java.net.URLConnection#connect()
- java.net.URLConnection#getInputStream()
- java.net.Socket#connect(java.net.SocketAddress)
- java.net.Socket#connect(java.net.SocketAddress, int)
- java.nio.channels.SocketChannel#open(java.net.SocketAddress)
- java.nio.channels.SocketChannel#connect(java.net.SocketAddress)
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
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.

This PR adds a new option for `host_type`: `tag:TAGNAME` where `TAGNAME` is the tag field you defined for your ec2 instance.
For example if you defined a tag `my-elasticsearch-host` in ec2 and set it to `myhostname1.mydomain.com`, then
setting `host_type: tag:my-elasticsearch-host` will tell Discovery Ec2 plugin to read the host name from the
`my-elasticsearch-host` tag. In this case, it will be resolved to `myhostname1.mydomain.com`.
Closes#22566.
This commit adds a SpecialPermission constant and uses that constant
opposed to introducing new instances everywhere.
Additionally, this commit introduces a single static method to check that
the current code has permission. This avoids all the duplicated access
blocks that exist currently.
This is related to #22116. Certain plugins (discovery-azure-classic,
discovery-ec2, discovery-gce, repository-azure, repository-gcs, and
repository-s3) open socket connections. As SocketPermissions are
transitioned out of core, these plugins will require connect
permission. This pull request wraps operations that require these
permissions in doPrivileged blocks.
This integrates the mocksocket jar with elasticsearch tests. Mocksocket wraps actions requiring SocketPermissions in doPrivilege blocks. This will eventually allow SocketPermissions to be assigned to the mocksocket jar opposed to the entire elasticsearch codebase.
* Remove a checked exception, replacing it with `ParsingException`.
* Remove all Parser classes for the yaml sections, replacing them with static methods.
* Remove `ClientYamlTestFragmentParser`. Isn't used any more.
* Remove `ClientYamlTestSuiteParseContext`, replacing it with some static utility methods.
I did not rewrite the parsers using `ObjectParser` because I don't think it is worth it right now.
