When changing how the config path is configured (from a command-line
flag to an environment variable) we had to add BWC code in the build so
that we could form clusters with 5.x nodes in them. Now that this branch
has moved to 7.x, we no longer need to be BWC with 5.x for starting
nodes. This commit removes this dead BWC code.
Relates #26446
When starting a node in standalone tests, we sometimes use a wrapper
script as opposed to starting Elasticsearch directly (this is used for
backgrounding). On Windows, the path to this wrapper script can be
exceptionally long, exceeding the length of a batch script that cmd.exe
will invoke without whining. This commit replaces using the full path
name for this wrapper script by the short name for the wrapper script.
Additionally, the data, configuration, and jvm.options paths can also
end up being too long so we shorten those too. Care has to be taken with
the data directory because we usually rely on the node creating it on
startup but doing that will not be compatible with getting the short
name as that requires the directory already existing. Therefore, we
create that directory on-demand immediately before actually resolving
the short name.

At current, we do not feel there is enough of a reason to shade the low
level rest client. It caused problems with commons logging and IDE's
during the brief time it was used. We did not know exactly how many
users will need this, and decided that leaving shading out until we
gather more information is best. Users can still shade the jar
themselves. For information and feeback, see issue #26366.

We currently add the apache license/notice for elasticsearch to any
plugin that uses our ES plugin gradle plugin. However, each plugin
should be able to use their own license. This commit adds a licenseFile
and noticeFile property to the root of project's using BuildPlugin,
which is added to jar files for that project.
In some cases our Windows builds fail due to long path names that arise
from a combination of long build job names plus long sub-project
names. While newer versions of Windows can handle long paths, invoking
batch scripts longer than 260 characters via cmd.exe is still
problematic. This leads to failing integration tests because we can not
run the commands to install plugins, create the keystore, and start the
node. This commit handles this by converting all paths on Windows used
to start an Elasticsearch node to short path names.

This commit removes the keystore creation on elasticsearch startup, and
instead adds a plugin property which indicates the plugin needs the
keystore to exist. It does still make sure the keystore.seed exists on
ES startup, but through an "upgrade" method that loading the keystore in
Bootstrap calls.

This commit makes the security code aware of the Java 9 FilePermission changes (see #21534) and allows us to remove the `jdk.io.permissionsUseCanonicalPath` system property.
The client sniffer depends on the low-level REST client, while the Java high-level REST client and the transport client depend on Elasticsearch itself. Javadoc are not that useful unless they have links to the Elasticsearch classes in the latter case, and to the low-level REST client in the sniffer javadoc. This commit adds those links.
All of the snippets in our docs marked with `// TESTRESPONSE` are
checked against the response from Elasticsearch but, due to the
way they are implemented they are actually parsed as YAML instead
of JSON. Luckilly, all valid JSON is valid YAML! Unfurtunately
that means that invalid JSON has snuck into the exmples!
This adds a step during the build to parse them as JSON and fail
the build if they don't parse.
But no! It isn't quite that simple. The displayed text of some of
these responses looks like:
```
{
...
"aggregations": {
"range": {
"buckets": [
{
"to": 1.4436576E12,
"to_as_string": "10-2015",
"doc_count": 7,
"key": "*-10-2015"
},
{
"from": 1.4436576E12,
"from_as_string": "10-2015",
"doc_count": 0,
"key": "10-2015-*"
}
]
}
}
}
```
Note the `...` which isn't valid json but we like it anyway and want
it in the output. We use substitution rules to convert the `...`
into the response we expect. That yields a response that looks like:
```
{
"took": $body.took,"timed_out": false,"_shards": $body._shards,"hits": $body.hits,
"aggregations": {
"range": {
"buckets": [
{
"to": 1.4436576E12,
"to_as_string": "10-2015",
"doc_count": 7,
"key": "*-10-2015"
},
{
"from": 1.4436576E12,
"from_as_string": "10-2015",
"doc_count": 0,
"key": "10-2015-*"
}
]
}
}
}
```
That is what the tests consume but it isn't valid JSON! Oh no! We don't
want to go update all the substitution rules because that'd be huge and,
ultimately, wouldn't buy much. So we quote the `$body.took` bits before
parsing the JSON.
Note the responses that we use for the `_cat` APIs are all converted into
regexes and there is no expectation that they are valid JSON.
Closes#26233
The secure settings tool reads from stdIn and we use a closure to
provide a value for this. Yet, we evaluate they value too late and end up
with the last provided value for all keys.
The environment variable CONF_DIR was previously inconsistently used in
our packaging to customize the location of Elasticsearch configuration
files. The importance of this environment variable has increased
starting in 6.0.0 as it's now used consistently to ensure Elasticsearch
and all secondary scripts (e.g., elasticsearch-keystore) all use the
same configuration. The name CONF_DIR is there for legacy reasons yet
it's too generic. This commit renames CONF_DIR to ES_PATH_CONF.
Relates #26197
The build was ignoring suffixes like "beta1" and "rc1" on the version numbers which was causing the backwards compatibility packaging tests to fail because they expected to be upgrading from 6.0.0 even though they were actually upgrading from 6.0.0-beta1. This adds the suffixes to the information that the build scrapes from Version.java. It then uses those suffixes when it resolves artifacts build from the bwc branch and for testing.
Closes#26017
Compiling all of elasticsearch classes in one jvm, which is shared with
all of the loaded classes of gradle, can trip gc overhead limits. This
commit re-enables forking javac.
This commit updates the version for master to 7.0.0-alpha1. It also adds
the 6.1 version constant, and fixes many tests, as well as marking some
as awaits fix.
Closes#25893Closes#25870
Some REST tests can rapid-fire script compilations that exceed the
default script compilations per minute. Rather than subjecting ourselves
to spurious failures because of the limit being too low, we opt for a
larger limit here.
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).
Today we expose `IndexFieldDataService` outside of IndexService to do maintenance
or lookup field data in different ways. Yet, we have a streamlined way to access IndexFieldData
via `QueryShardContext` that should encapsulate all access to it. This also ensures that we control all other functionality like cache clearing etc.
This change also removes the `recycler` option from `ClearIndicesCacheRequest` this option is a no-op and should have been removed long ago.
Stored fields were still being accessed for nested inner hits even if the _source was not requested.
This was done to figure out the id of the root document. However this is already known higher up the stack.
So instead this change adds the id to the nested search context, so that it is no longer required to be fetched via the stored fields.
In case the _source is large and no source is requested then hot threads like these ones would still appear:

using shadowJar gradle plugin. All projects that depended on the
existing jar have been converted to using the 'org.elasticsearch.client'

Using `sh` means we used whatever default the system has, which is `dash` on
Ubuntu, even though our startup script is written for bash (see the shebang).
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)

This commit introduces a nio based tcp transport into framework for

Currently Elasticsearch uses a simple blocking tcp transport for

where our current transport (netty) is non-blocking.
The point of this commit is to introduce a testing variant that more
closely matches the behavior of production instances.

You can continue a test started in a previous snippet by marking the
next snippet with `// TEST[continued]`. The trouble is, if you mark the
first snippet in a file with `// TEST[continued]` you'd get difficult
to predict behavior because you'd continue the test started in another
file. This will usually create a test that fails the build but it isn't
easy to track down what you did wrong. This commit catches this
scenario up front and fails the build with a useful error message.
Similarly, if you put `// TEST[continued]` directly after a
`// TESTSETUP` section then the docs tests will fail to run but the
error message did not point you to the `// TEST[continued]` snippet.
This commit catches this scenario up front as well and fails the build

Removes the `assemble` task from the `build` task when we have
removed `assemble` from the project. We removed `assemble` from
projects that aren't published so our releases will be faster. But
That broke CI because CI builds with `gradle precommit build` and,
it turns out, that `build` includes `check` and `assemble`. With
this change CI will only run `check` for projects without an
`assemble`.
Removes the `assemble` task from projects that are not published.
This should speed up `gradle assemble` by skipping projects that
don't need to be built. Which is useful because `gradle assemble`
is how we cut releases.
This snapshot has faster range queries on range fields (LUCENE-7828), more
accurate norms (LUCENE-7730) and the ability to use fake term frequencies
(LUCENE-7854).
This change removes the `postings` highlighter. This highlighter has been removed from Lucene master (7.x) because it behaves
exactly like the `unified` highlighter when index_options is set to `offsets`:
https://issues.apache.org/jira/browse/LUCENE-7815
It also makes the `unified` highlighter the default choice for highlighting a field (if `type` is not provided).
The strategy used internally by this highlighter remain the same as before, it checks `term_vectors` first, then `postings` and ultimately it re-analyzes the text.
Ultimately it rewrites the docs so that the options that the `unified` highlighter cannot handle are clearly marked as such.
There are few features that the `unified` highlighter is not able to handle which is why the other highlighters (`plain` and `fvh`) are still available.
I'll open separate issues for these features and we'll deprecate the `fvh` and `plain` highlighters when full support for these features have been added to the `unified`.
Pins the random testing seed at build start rather than letting
it vary with every randomized testing invocation. This is useful
for projects where random decisions in one randomized testing run
can effect the outcome of a second randomized testing run such as
the full cluster restart tests.
The goal isn't for tests to be able to assume that random decision
will be the same in both tests. It is more to make sure that the
seed printed when a test fails reproduces the appropriate random
decisions. And pinning the seed at startup should do just that.
This works by taking the key passed as a system property if one
is passed, otherwise picking a random long and getting it into
appropriate key format. The build just calls
`new Random().nextLong()` to get the seed while randomized testing
uses a Murmur3 hash of `System.nanoTime`.
This adds an option to `ClusterConfiguration` to preserve the
`shared` directory when starting up a new cluster and switches
the `qa:full-cluster-restart` tests to use it rather than
disable the clean shared task.

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.
When transitive dependencies are disable for a dependency, gradle adds a

Adds a "magic" key to the yaml testing stash mostly for use with
documentation tests. When unstashing an object, `$_path` is the
path into the current position in the object you are unstashing.
This means that in docs tests you can use
`// TESTRESPONSEs/somevalue/$body.${_path}/` to mean "replace
`somevalue` with whatever is the response in the same position."
Compare how you must carefully mock out all the numbers in the profile
response without this change:

When Elasticsearch dies during a standalone REST test we might leave a
dirty PID file laying around. We tried to log about this, but the log
messages contained references to undefined variables so we simply died
instead of providing a helpful message to run clean. This commit
addresses this issue.
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 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.
This is almost exclusively for docs test which frequently match the
entire response. This allow something like:
```
- set: {nodes.$master.http.publish_address: host}
- match:
$body:
{
"nodes": {
$host: {
... stuff in here ...
}
}
}
```
This should make it possible for the docs tests to work with
unpredictable keys.
The disruption tests sit in a single test suite which causes these tests
to be single-threaded. We can split this test suite into multiple suites
(logically, of course) enabling them to be run in parallel reducing the
total run time of all integration tests in core. This commit splits the
discovery with service disruptions test suite into three suites
- master disruptions
- discovery disruptions
- cluster disruptions
The last one could probably be better named, it is meant to represent
performing actions in the cluster (indexing, failing a shard, etc.)
while a disruption is taking place.

This starts breaking up the `UpdateHelper.prepare` method so that each piece can

Note however, that I did add a TODO about `ctx.op` leniency, which I'd love to

Previously you could set the system property tests.es.path.data and
start the run task with a custom data directory. A change in core to
detect duplicate settings broke this. That change should stay, but we
can work around this easily by only setting path.data to the data

TransportService and RemoteClusterService are closely coupled already today
and to simplify remote cluster integration down the road it can be a direct
dependency of TransportService. This change moves RemoteClusterService into
TransportService with the goal to make it a hidden implementation detail
of TransportService in followup changes.
This adds `-XX:-OmitStackTraceInFastThrow` to the JVM arguments
which *should* prevent the JVM from omitting stack traces on
common exception sites. Even though these sites are common, we'd
still like the exceptions to debug them.
This also adds the flag when running tests and adapts some tests
that had workarounds for the absense of the flag.

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.
Creates a new task `namingConventionsMain`, that runs on the
`buildSrc` and `test:framework` projects and fails the build if
any of the classes in the main artifacts are named like tests or
are non-abstract subclasses of ESTestCase.
It also fixes the three tests that would cause it to fail.
Start moving built in analysis components into the new analysis-common
module. The goal of this project is:
1. Remove core's dependency on lucene-analyzers-common.jar which should
shrink the dependencies for transport client and high level rest client.
2. Prove that analysis plugins can do all the "built in" things by moving all
"built in" behavior to a plugin.
3. Force tests not to depend on any oddball analyzer behavior. If tests
need anything more than the standard analyzer they can use the mock
analyzer provided by Lucene's test infrastructure.
This commit adds a call to jstack to see where each node is stuck when
starting up, if a timeout occurs. This also decreases the timeout back
to 30 seconds.
We want to upgrade to Lucene 7 ahead of time in order to be able to check whether it causes any trouble to Elasticsearch before Lucene 7.0 gets released. From a user perspective, the main benefit of this upgrade is the enhanced support for sparse fields, whose resource consumption is now function of the number of docs that have a value rather than the total number of docs in the index.
Some notes about the change:
- it includes the deprecation of the `disable_coord` parameter of the `bool` and `common_terms` queries: Lucene has removed support for coord factors
- it includes the deprecation of the `index.similarity.base` expert setting, since it was only useful to configure coords and query norms, which have both been removed
- two tests have been marked with `@AwaitsFix` because of #23966, which we intend to address after the merge
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.
This new version of jna is rebuilt from the official release of jna, but
with native libs linked against older glibc in order to support all
platforms elasticsearch supports.

This reverts the line limit change in #23623 - this PR doesn't touch the suppression file since we are moving towards automatic code formatting which makes it mainly obsolete.
Adds the option for a plugin to specify extra directories containing notices
and licenses files to be incorporated into the overall notices file that is
generated for the plugin.
This can be useful, for example, where the plugin has a non-Java dependency
that itself incorporates many 3rd party components.
The buffer limit should have been configurable already, but the factory constructor is package private so it is truly configurable only from the org.elasticsearch.client package. Also the HttpAsyncResponseConsumerFactory interface was package private, so it could only be implemented from the org.elasticsearch.client package.
Closes#23958
This commit upgrades the Log4j dependencies from version 2.7 to version
2.8.2. This release includes a fix for a case where Log4j could lose
exceptions in the presence of a security manager.

This commit puts all the classes in the repository-s3 plugin into a
single package. In addition to simplifying the plugin, it will make it
easier to test as things that should be package private will not be
difficult to use inside tests alone.
The method Boolean#getBoolean is dangerous. It is too easy to mistakenly
invoke this method thinking that it is parsing a string as a
boolean. However, what it actually does is get a system property with
the specified string, and then attempts to use usual crappy boolean
parsing in the JDK to parse that system property as boolean with
complete leniency (it parses every input value into either true or
false); that is, this method amounts to invoking
Boolean#parseBoolean(String) on the result of
System#getProperty(String). Boo. This commit bans usage of this method.

Now that we are on gradle 3.3, we can take advantage of a fix that was
made in 2.14 which properly handles disabling transitive dependencies in
pom generation. As it was currently, we actually ended up generated two
exclusions sections in the generated pom. This is yet another example of
why we need validation on the pom files with our generation here, but I
leave that for another day because I still don't know a good way to do
it.
This moves `updateReplicaRequest` to `createPrimaryResponse` and separates the
translog updating to be a separate function so that the function purpose is more
easily understood (and testable).
It also separates the logic for `MappingUpdatePerformer` into two functions,
`updateMappingsIfNeeded` and `verifyMappings` so they don't do too much in a
single function. This allows finer-grained error testing for when a mapping
fails to parse or be applied.
Finally, it separates parsing and version validation for
`executeIndexRequestOnReplica` into a separate
method (`prepareIndexOperationOnReplica`) and adds a test for it.

This commit adds a build listener to the integ test runner which will
print out an excerpt of the logs from the integ test cluster if the test
run fails. There are future improvements that can be made (for example,
to dump excerpts from dependent clusters like in tribe node tests), but
this is a start, and would help with simple rest tests failures that we
currently don't know what actually happened on the node.
This will allow us to get rid of deprecation warnings that appear when
using 3.3, and also get rid of extra logic for 2.13 required because of
the progress logger.
Search took time uses an absolute clock to measure elapsed time, and
then tries to deal with the complexities of using an absolute clock for
this purpose. Instead, we should use a high-precision monotonic relative
clock that is designed exactly for measuring elapsed time. This commit
modifies the search infrastructure to use a relative clock for measuring
took time, but still provides an absolute clock for the components of
search that require a real clock (e.g., index name expression
resolution, etc.).

This commit creates a keystore and adds settings to it during the
cluster formation for integration tests. Users can define a
`keyStoreSetting` in build files for settings that need to be placed in
the keystore.
