The rpm, deb and tar distributions were removed some time ago from maven
central. The zip distribution still exists there, but it does not need
to. Instead, this commit sets up an ivy repository with pattern pointing
to the elasticsearch artifacts download service. Note that the
integ-test-zip remains in maven central, since it is not present in the
download service.
- The current version was hard coded in the test, causing it to fail as
we removed the qualifier
- also applied the base plugin to the root project to get the `clean`
task to work as expected. This was preventing the failure from
reproducing locally.
* Manage dependencies for test clusters
Create a configuration and add the distribution to it automatically.
A task is created and added as a dependency to any task that uses a test
cluster.
The task extracts all the zip archives ( only zip support for now )
in the configuration.
We do this only once because most tests mostly use the same distribution
and thus we can avoid extracting it multiple times.
With this we will be able to start the node from the same files which
will most of the time live in OS caches or COW if the
configuration requires it.
* Introduce property to set version qualifier
- VersionProperties.elasticsearch is now a string which can have qualifier
and snapshot too
- The Version class in the build no longer cares about snapshot and
qualifier.
This change introduces stats per processors. Total, time, failed,
current are currently supported. All pipelines will now show all
top level processors that belong to it. Failure processors are not
displayed, however, the time taken to execute the failure chain is part
of the stats for the top level processor.
The processor name is the type of the processor, ordered as defined in
the pipeline. If a tag for the processor is found, then the tag is
appended to the type.
Pipeline processors will have the pipeline name appended to the name of
the name of the processors (before the tag if one exists). If more
then one pipeline is used to process the document, then each pipeline
will carry its own stats. The outer most pipeline will also include the
inner most pipeline stats.
Conditional processors will only included in the stats if the condition evaluates
to true.
With the introduction of immutable workers into our CI, we now have a
problem where we would have to download dependencies on every single
build. To this end our infrastructure team has introduced the
possibility to download dependencies one time and then bake these into
the base immutable worker image. For this, we introduce our version of
this special script which runs a task that downloads all dependencies of
all configurations. With this script, our infrastructure team will be
rebuilding these images on an at-least daily basis. This helps us avoid
having to download the dependencies for every single build.
This reworks how we configure the `shadow` plugin in the build. The major
change is that we no longer bundle dependencies in the `compile` configuration,
instead we bundle dependencies in the new `bundle` configuration. This feels
more right because it is a little more "opt in" rather than "opt out" and the
name of the `bundle` configuration is a little more obvious.
As an neat side effect of this, the `runtimeElements` configuration used when
one project depends on another now contains exactly the dependencies needed
to run the project so you no longer need to reference projects that use the
shadow plugin like this:
```
testCompile project(path: ':client:rest-high-level', configuration: 'shadow')
```
You can instead use the much more normal:
```
testCompile "org.elasticsearch.client:elasticsearch-rest-high-level-client:${version}"
```
Add tests for build-tools to make sure example plugins build stand-alone using it.
This will catch issues such as referencing files from the buildSrc directly, breaking external uses of build-tools.
* Determine the minimum gradle version based on the wrapper
This is restrictive and forces users of the plugin to move together with
us, but without integration tests it's close to impossible to make sure
that the claimed compatability is really there.
If we do want to offer more flexibility, we should add those tests
first.
* Track gradle version in individual file
* PR review
This bundles the x-pack:protocol project into the x-pack:plugin:core
project because we'd like folks to consider it an implementation detail
of our build rather than a separate artifact to be managed and depended
on. It is now bundled into both x-pack:plugin:core and
client:rest-high-level. To make this work I had to fix a few things.
Firstly, I had to make PluginBuildPlugin work with the shadow plugin.
In that case we have to bundle only the `shadow` dependencies and the
shadow jar.
Secondly, every reference to x-pack:plugin:core has to use the `shadow`
configuration. Without that the reference is missing all of the
un-shadowed dependencies. I tried to make it so that applying the shadow
plugin automatically redefines the `default` configuration to mirror the
`shadow` configuration which would allow us to use bare project references
to the x-pack:plugin:core project but I couldn't make it work. It'd *look*
like it works but then fail for transitive dependencies anyway. I think
it is still a good thing to do but I don't have the willpower to do it
now.
Finally, I had to fix an issue where Eclipse and IntelliJ didn't properly
reference shadowed transitive dependencies. Neither IDE supports shadowing
natively so they have to reference the shadowed projects. We fix this by
detecting `shadow` dependencies when in "Intellij mode" or "Eclipse mode"
and adding `runtime` dependencies to the same target. This convinces
IntelliJ and Eclipse to play nice.
* Detect and prevent configuration that triggers a Gradle bug
As we found in #31862, this can lead to a lot of wasted time as it's not
immediatly obvius what's going on.
Givent how many projects we have it's getting increasingly easier to run
into gradle/gradle#847.
The shadow plugin disables the jar task but we still attempted to extract
the jar to see if it had the right license and notice file. This skips
the extraction and those tests if the jar is built for any reason which
fixes projects that use the shadow plugin.
Moves the customizations to the build to produce nice shadow jars and
javadocs into common build code, mostly BuildPlugin with a little into
the root build.gradle file. This means that any project that applies the
shadow plugin will automatically be set up just like the high level rest
client:
* The non-shadow jar will not be built
* The shadow jar will not have a "classifier"
* Tests will run against the shadow jar
* Javadoc will include all of the shadowed classes
* Service files in `META-INF/services` will be merged
* add support for is_write_index in put-alias body parsing
The Rest Put-Alias Action does separate parsing of the alias body
to construct the IndicesAliasesRequest. This extra parsing
was missed in #30703.
* test flag was not just ignored by the parser
* disable backcompat tests
It looks like Eclipse's compiler server recently changed something so
our "eclipse detector" stopped working for it. I've updated the detector
so it ought to work now.
This PR does the server side work for adding the Get Index API to the REST
high-level-client, namely moving resolving default settings to the
transport action. A follow up would be the client side changes.

Closes#31324. The issue has full context in comments.
With this change the `test` task becomes nothing more than an alias for `utest`.
Some of the stand alone tests that had a `test` task now have `integTest`, and a
few of them that used to have `integTest` to run multiple tests now only
have `check`.
This will also help separarate unit/micro tests from integration tests.

For 6.3 we renamed the `tar` and `zip` distributions to `oss-tar` and
`oss-zip`. Then we added new `tar` and `zip` distributions that contain
x-pack and are licensed under the Elastic License. Unfortunately we
accidentally generated POM files along side the new `tar` and `zip`
distributions that incorrectly claimed that they were Apache 2 licensed.
Oooops.
This fixes the license on the POMs generated for the `tar` and `zip`
distributions.
The goal of this commit is to address unknown licenses when producing
the dependencies info report. We have two different checks that we run
on licenses. The first check is whether or not we have stashed a copy of
the license text for a dependency in the repository. The second is to
map every dependency to a license type (e.g., BSD 3-clause). The problem
here is that the way we were handling licenses in the second check
differs from how we handle licenses in the first check. The first check
works by finding a license file with the name of the artifact followed
by the text -LICENSE.txt. Yet in some cases we allow mapping an artifact
name to another name used to check for the license (e.g., we map
lucene-.* to lucene, and opensaml-.* to shibboleth. The second check
understood the first way of looking for a license file but not the
second way. So in this commit we teach the second check about the
mappings from artifact names to license names. We do this by copying the
configuration from the dependencyLicenses task to the dependenciesInfo
task and then reusing the code from the first check in the second
check. There were some other challenges here though. For example,
dependenciesInfo was checking too many dependencies. For now, we should
only be checking direct dependencies and leaving transitive dependencies
from another org.elasticsearch artifact to that artifact (we want to do
this differently in a follow-up). We also want to disable
dependenciesInfo for projects that we do not publish, users only care
about licenses they might be exposed to if they use our assembled
products. With all of the changes in this commit we have eliminated all
unknown licenses. A follow-up will enforce that when we add a new
dependency it does not get mapped to unknown, these will be forbidden in
the future. Therefore, with this change and earlier changes are left
having no unknown licenses and two custom licenses; custom here means it
does not map to an SPDX license type. Those two licenses are xz and
ldapsdk. A future change will not allow additional custom licenses
unless they are explicitly whitelisted. This ensures that if a new
dependency is added it is mapped to an SPDX license or mapped to custom
because it does not have an SPDX license.
This commit adds a check that any class in X-Pack that is a feature
aware custom also implements the appropriate mix-in interface in
X-Pack. These interfaces provide a default implementation of
FeatureAware#getRequiredFeature that returns that x-pack is the required
feature. By implementing this interface, this gives a consistent way for
X-Pack feature aware customs to return the appopriate required feature
and this check enforces that all such feature aware customs return the
appropriate required feature.
* Accept Gradle build scan argreement

This commit moves the gradle wrapper jar file to a hidden directory, so
that it does not clutter the top level names seen when doing an ls in
the project. The actual jar file is never manually edited, and only
changed by running `./gradlew wrapper ...` so it is not important for
this directory to be "visible".
Adds tasks that check that the all jars that we build have LICENSE.txt
and NOTICE.txt files and that the files are correct. Sets check to
depend on these task.
This is mostly there for extra parnoia because we automatically
configure all Jar tasks to include the LICENSE.txt and NOTICE.txt
files anyway. But it is quite possible to add configuration to those
tasks that would override either file.
This causes check to depend on several more things than it used to.
Take, for example, javadoc:
check depends on the new verifyJavadocJarNotice which depends on
extractJavadocJar which depends on javadocJar which depends on
javadoc, this check now depends on javadoc.
This commit moves the apache and elastic license files into a new
root level `licenses` directory and rewrites the top level LICENSE.txt
to clarify the repository has a mix of apache and elastic licensed code.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
Fails the build if any subprojects of `:libs` have dependencies in `:libs`
except for `:libs:elasticsearch-core`.
Since we now have three places where we resolve project substitutions
I've added `dependencyToProject` to `project.ext` in all projects. It
resolves both `project` style dependencies and "external" style (like
"org.elasticsearch:elasticsearch-core:${version}") dependencies to
`Project`s using the `projectSubstitutions`. I use this new function all
three places where resovle project substitutions.
Finally this pulls `apply plugin: 'elasticsearch.build'` out of
`libs/*/build.gradle` and into a subprojects clause in
`libs/build.gradle`. I do this entirely so that I can call
`tasks.precommit.dependsOn checkDependencies` without waiting for the
subprojects to be evaluated or worrying about whether or not they have
`precommit` set up in a normal way.
Rather than checking a substring match, now that
VersionProperties#elasticsearch is a strongly-typed instance of Version,
we can use the Version#isSnapshot convenience method. This commit
switches the root build file to do this.
Today we have a nodeVersion property on the NodeInfo class that we use
to carry around information about a standalone node that we will start
during tests. This property is a String which we usually end up parsing
to a Version anyway to do various checks on it. This can end up
happening a lot during configuration so it would be more efficient and
safer to have this already be strongly-typed as a Version and parsed
from a String only once for each instance of NodeInfo. Therefore, this
commit makes NodeInfo#nodeVersion strongly-typed as a Version.
* Begin moving XContent to a separate lib/artifact
This commit moves a large portion of the XContent code from the `server` project
to the `libs/xcontent` project. For the pieces that have been moved, some
helpers have been duplicated to allow them to be decoupled from ES helper
classes. In addition, `Booleans` and `CheckedFunction` have been moved to the
`elasticsearch-core` project.
This decoupling is a move so that we can eventually make things like the
high-level REST client not rely on the entire ES jar, only the parts it needs.
There are some pieces that are still not decoupled, in particular some of the
XContent tests still remain in the server project, this is because they test a
large portion of the pluggable xcontent pieces through
`XContentElasticsearchException`. They may be decoupled in future work.
Additionally, there may be more piecese that we want to move to the xcontent lib
in the future that are not part of this PR, this is a starting point.

This commit adds intermediate gradle projects for archive based
distributions (zip, tar) and package based distributions (rpm, deb). The
grouping allows the common distribution build file to be considerably
shorter and clearly separated from the common zip/tar and rpm/deb
configuration.
Generalizing BWC building so that there is less code to modify for a release. This ensures we do not
need to think about what major or minor version is in the gradle code. It follows the general rules of the
elastic release structure. For more information on the rules, see the VersionCollection's javadoc.
This also removes the additional bwc snapshots that will never be released, such as 6.0.2, which were
being built and tested against every time we ran bwc tests.
Additionally, it creates 4 new projects that correspond to the different types of snapshots that may exist
for a given version. Its possible to now run those individual tasks to work out bwc logic whereas
previously it was impossible and the entire suite of bwc tests had to be run to work out any logic
changes in the build tools' bwc project. Please note that if the project does not make sense for the
version that is current, that an error will be thrown from that individual project if an attempt is made to
run it.
This should allow for automating the version bumps as well, since it removes all the hardcoded version
logic from the configs.
When elasticsearch was originally moved to gradle, the "provided" equivalent in maven had to be done through a plugin. Since then, gradle added the "compileOnly" configuration. This commit removes the provided plugin and replaces all uses with compileOnly.
The bwc tests can be disabled in order to facilitate commits necessary
to older branches to maintain backcompat. A check already exists to
ensure this flag is not left disabled too long (once a day by the
branchConsistency check). However, it can be surprising if you try
running bwc tests explicitly and they look like nothing is happening.
This commit adds a warning during configuration to ensure it is clear
the bwc tests are disabled and enforces a link to a PR which is in the
process of being backported.
Plugin descriptors currently contain an elasticsearch version,
which the plugin was built against, and a java version, which the plugin
was built with. These versions are read and validated, but not stored.
This commit keeps them in PluginInfo so they can be used later.
While seeing the elasticsearch version is less interesting (since it is
enforced to match that of the running elasticsearc node), the java
version is interesting since we only validate the format, not the actual
version. This also makes PluginInfo have full parity with the plugin
properties file.
These tests were disabled to facilitate backport of a PR which is not
yet complete. These tests were accidentally reenabled after a merge
conflict was resolved in the wrong direction. This commit addresses this
issue.
Adds allow_partial_search_results flag to search requests with default setting = true.
When false, will error if search either timeouts, has partial errors or has missing shards rather
than returning partial search results. A cluster-level setting provides a default for search requests with no flag.
Closes#27435
This is related to #27933. It introduces a jar named elasticsearch-core
in the lib directory. This commit moves the JarHell class from server to
elasticsearch-core. Additionally, PathUtils and some of Loggers are
moved as JarHell depends on them.
We have agreed to introduce the Gradle wrapper to simplify workflows for
developers, and managing infrastructure (e.g., CI, release builds, etc.)
as well as consideration for the fact that other projects in our stack
use Gradle and do not necessarily want to be tied to our Gradle version.
Relates #28065
This commit adds the infrastructure to plugin building and loading to
allow one plugin to extend another. That is, one plugin may extend
another by the "parent" plugin allowing itself to be extended through
java SPI. When all plugins extending a plugin are finished loading, the
"parent" plugin has a callback (through the ExtensiblePlugin interface)
allowing it to reload SPI.
This commit also adds an example plugin which uses as-yet implemented
extensibility (adding to the painless whitelist).
This is related to #27802. This commit adds a jar called
elasticsearch-nio that contains the base nio classes that will be used
for the tcp nio transport and eventually the http nio transport.
The jar does not depend on elasticsearch:core, so all references to core
have been removed.
This change removes the module named aggs-composite and adds the `composite` aggs
as a core aggregation. This allows other plugins to use this new aggregation
and simplifies the integration in the HL rest client.
Projects the depend on the CLI currently depend on core. This should not
always be the case. The EnvironmentAwareCommand will remain in :core,
but the rest of the CLI components have been moved into their own
subproject of :core, :core:cli.
* This change adds a module called `aggs-composite` that defines a new aggregation named `composite`.
The `composite` aggregation is a multi-buckets aggregation that creates composite buckets made of multiple sources.
The sources for each bucket can be defined as:
* A `terms` source, values are extracted from a field or a script.
* A `date_histogram` source, values are extracted from a date field and rounded to the provided interval.
This aggregation can be used to retrieve all buckets of a deeply nested aggregation by flattening the nested aggregation in composite buckets.
A composite buckets is composed of one value per source and is built for each document as the combinations of values in the provided sources.
For instance the following aggregation:
````
"test_agg": {
"terms": {
"field": "field1"
},
"aggs": {
"nested_test_agg":
"terms": {
"field": "field2"
}
}
}
````
... which retrieves the top N terms for `field1` and for each top term in `field1` the top N terms for `field2`, can be replaced by a `composite` aggregation in order to retrieve **all** the combinations of `field1`, `field2` in the matching documents:
````
"composite_agg": {
"composite": {
"sources": [
{
"field1": {
"terms": {
"field": "field1"
}
}
},
{
"field2": {
"terms": {
"field": "field2"
}
}
},
}
}
````
The response of the aggregation looks like this:
````
"aggregations": {
"composite_agg": {
"buckets": [
{
"key": {
"field1": "alabama",
"field2": "almanach"
},
"doc_count": 100
},
{
"key": {
"field1": "alabama",
"field2": "calendar"
},
"doc_count": 1
},
{
"key": {
"field1": "arizona",
"field2": "calendar"
},
"doc_count": 1
}
]
}
}
````
By default this aggregation returns 10 buckets sorted in ascending order of the composite key.
Pagination can be achieved by providing `after` values, the values of the composite key to aggregate after.
For instance the following aggregation will aggregate all composite keys that sorts after `arizona, calendar`:
````
"composite_agg": {
"composite": {
"after": {"field1": "alabama", "field2": "calendar"},
"size": 100,
"sources": [
{
"field1": {
"terms": {
"field": "field1"
}
}
},
{
"field2": {
"terms": {
"field": "field2"
}
}
}
}
}
````
This aggregation is optimized for indices that set an index sorting that match the composite source definition.
For instance the aggregation above could run faster on indices that defines an index sorting like this:
````
"settings": {
"index.sort.field": ["field1", "field2"]
}
````
In this case the `composite` aggregation can early terminate on each segment.
This aggregation also accepts multi-valued field but disables early termination for these fields even if index sorting matches the sources definition.
This is mandatory because index sorting picks only one value per document to perform the sort.
It is the exciting return of the global checkpoint background
sync. Long, long ago, in snapshot version far, far away we had and only
had a global checkpoint background sync. This sync would fire
periodically and send the global checkpoint from the primary shard to
the replicas so that they could update their local knowledge of the
global checkpoint. Later in time, as we sped ahead towards finalizing
the initial version of sequence IDs, we realized that we need the global
checkpoint updates to be inline. This means that on a replication
operation, the primary shard would piggy back the global checkpoint with
the replication operation to the replicas. The replicas would update
their local knowledge of the global checkpoint and reply with their
local checkpoint. However, this could allow the global checkpoint on the
primary to advance again and the replicas would fall behind in their
local knowledge of the global checkpoint. If another replication
operation never fired, then the replicas would be permanently behind. To
account for this, we added one more sync that would fire when the
primary shard fell idle. However, this has problems:
- the shard idle timer defaults to five minutes, a long time to wait
for the replicas to learn of the new global checkpoint
- if a replica missed the sync, there was no follow-up sync to catch
them up
- there is an inherent race condition where the primary shard could
fall idle mid-operation (after having sent the replication request to
the replicas); in this case, there would never be a background sync
after the operation completes
- tying the global checkpoint sync to the idle timer was never natural
To fix this, we add two additional changes for the global checkpoint to
be synced to the replicas. The first is that we add a post-operation
sync that only fires if there are no operations in flight and there is a
lagging replica. This gives us a chance to sync the global checkpoint to
the replicas immediately after an operation so that they are always kept
up to date. The second is that we add back a global checkpoint
background sync that fires on a timer. This timer fires every thirty
seconds, and is not configurable (for simplicity). This background sync
is smarter than what we had previously in the sense that it only sends a
sync if the global checkpoint on at least one replica is lagging that of
the primary. When the timer fires, we can compare the global checkpoint
on the primary to its knowledge of the global checkpoint on the replicas
and only send a sync if there is a shard behind.
Relates #26591
This commit reenables the BWC tests after they were disabled for
backporting the change to track global checkpoints of shard copies on
the primary.
Relates #26666
This commit adds local tracking of the global checkpoints on all shard
copies when a global checkpoint tracker is operating in primary
mode. With this, we relay the global checkpoint on a shard copy back to
the primary shard during replication operations. This serves as another
step towards adding a background sync of the global checkpoint to the
shard copies.
Relates #26666
The new ops based recovery, introduce as part of #10708, is based on the assumption that all operations below the global checkpoint known to the replica do not need to be synced with the primary. This is based on the guarantee that all ops below it are available on primary and they are equal. Under normal operations this guarantee holds. Sadly, it can be violated when a primary is restored from an old snapshot. At the point the restore primary can miss operations below the replica's global checkpoint, or even worse may have total different operations at the same spot. This PR introduces the notion of a history uuid to be able to capture the difference with the restored primary (in a follow up PR).
The History UUID is generated by a primary when it is first created and is synced to the replicas which are recovered via a file based recovery. The PR adds a requirement to ops based recovery to make sure that the history uuid of the source and the target are equal. Under normal operations, all shard copies will stay with that history uuid for the rest of the index lifetime and thus this is a noop. However, it gives us a place to guarantee we fall back to file base syncing in special events like a restore from snapshot (to be done as a follow up) and when someone calls the truncate translog command which can go wrong when combined with primary recovery (this is done in this PR).
We considered in the past to use the translog uuid for this function (i.e., sync it across copies) and thus avoid adding an extra identifier. This idea was rejected as it removes the ability to verify that a specific translog really belongs to a specific lucene index. We also feel that having a history uuid will serve us well in the future.
Javadoc linking between projects currently relies on
projectSubstitutions. However, that is an extension variable that is not
part of BuildPlugin. This commit moves the javadoc linking into the root
build.gradle, alongside where projectSubstitutions are defined.
Adds support for bulk items to be aborted before they are processed by the TransportShardBulkAction.
This can be used by an ActionFilter to reject a subset of the items in a bulk action without rejecting the whole action (or all the items for a shard).
