Today we allow adding entries from a file or from a string, yet we
internally maintain this distinction such that if you try to add a value
from a file for a setting that expects a string or add a value from a
string for a setting that expects a file, you will have a bad time. This
causes a pain for operators such that for each setting they need to know
this difference. Yet, we do not need to maintain this distinction
internally as they are bytes after all. This commit removes that
distinction and includes logic to upgrade legacy keystores.
This commit bumps the bundled JDK to version 12.0.1. Note that we had to
add a new pattern here as Oracle has changed the source of the
builds. This commit will be backported to 6.7 in a different form to
bump the bundled JDK in the Docker images too.
hamcrest has some improvements in newer versions, like FileMatchers
that make assertions regarding file exists cleaner. This commit upgrades
to the latest version of hamcrest so we can start using new and improved
matchers.
To reduce configuration time, we fork some threads to compute the Java
version for the various configured Javas. However, as the number of
JAVA${N}_HOME variable increases, the current implementation creates as
many threads as there are such variables, which could be more than the
number of physical cores on the machine. It is not likely that we would
see benefits to trying to execute all of these once beyond the number of
physical cores (maybe simultaneous multi-threading helps though, who
knows. Therefore, this commit limits the parallelization here to the
number number of physical cores.
If no Java versions are set then when we size the executor thread pool
we end up with zero threads, which is illegal. This commit avoids that
problem by only starting the executor when needed.
ClusterFormationTasks auto configured these properties for clusters.
This PR adds FIPS specific configuration across all test clusters from
the main build script to prevent coupling betwwen testclusters and the
build plugin.
Closes#40904
This will help with reproduction lines and running tests form IDEs and
other operations that are quick and executed often enough for the
configuration time to matter.
Running Gradle with a FIPS JVM is not supproted, so if the runtime JVM
is the same one, no need to spend time checking for fips support.
Verification of the JAVA<version>_HOME env vars is now async and
parallel so it doesn't block configuration.
This PR adds additional cleanup when stopping the node.
The data dir is excepted because it gets reused in some tests.
Without this cleanup the number of working dir copies could grew to
exhaust all available disk space.
This is related to #36652. We intend to deprecate a number of transport
settings in 7.x and remove them in 8.0. This commit removes the string
usages of these settings.
With the 7.0.0 release, we switched to download the packages instead of
using locally built ones.
This PR fixes the artifact names to include the architecture as
introduced in the 7.0.0 release.
* Replace usages RandomizedTestingTask with built-in Gradle Test (#40978)
This commit replaces the existing RandomizedTestingTask and supporting code with Gradle's built-in JUnit support via the Test task type. Additionally, the previous workaround to disable all tasks named "test" and create new unit testing tasks named "unitTest" has been removed such that the "test" task now runs unit tests as per the normal Gradle Java plugin conventions.
(cherry picked from commit 323f312bbc829a63056a79ebe45adced5099f6e6)
* Fix forking JVM runner
* Don't bump shadow plugin version
This commit sets the version to ensure that we use the bundled Java when
running integration tests for all eligible versions. In particular,
since we started bundling Java with 7.0.0, this commits sets said
version to 7.0.0.
This change updates our version of httpclient to version 4.5.8, which
contains the fix for HTTPCLIENT-1968, which is a bug where the client
started re-writing paths that contained encoded reserved characters
with their unreserved form.
Many gradle projects specifically use the -try exclude flag, because
there are many cases where auto-closeable resource ignore is never
referenced in body of corresponding try statement. Suppressing this
warning specifically in each case that it happens using
`@SuppressWarnings("try")` would be very verbose.
This change removes `-try` from any gradle project and adds it to the
build plugin. Also this change removes exclude flags from gradle projects
that is already specified in build plugin (for example -deprecation).
Relates to #40366
By default, in integ tests we wait for the standalone cluster to start
by using the ant Get task to retrieve the cluster health endpoint.
However the ant task has no facilities for customising the trusted
CAs for a https resource, so if the integ test cluster has TLS enabled
on the http interface (using a custom CA) we need a separate utility
for that purpose.
Backport of: #40573
* Run the build integ test in parallel
Because the randomized runner lives in buildSrc, we run these tests with
the Gradle runner, and had no parallelism configured so far.
* Handle Windows and "auto" better
Replaces the vagrant based kerberos fixtures with docker based test fixtures plugin.
The configuration is now entirely static on the docker side and no longer driven by Gradle,
also two different services are being configured since there are two different consumers of the fixture that can run in parallel and require different configurations.
* Add support for setting and keystore settings
* system properties and env var config
* use testclusters for repository-s3
* Some cleanup of the build.gradle file for plugin-s3
* add runner {} to rest integ test task
The platformTest gradle task was a packaging test meant to ensure unit
tests run on the various supported operating systems without relying on
CI to maintain a full matrix of platforms. Howevever, it never really
worked out as intended and is now additional code in our vagrant setup
to maintain. This commit removes the platformTest task.
* Revert "Configure TMP for test nodes on Windows (#39959)"
This reverts commit 97562a874fcb1f29fb05272ab860a0307e97d1aa.
* Configure a tmp dir without spaces
* Pass on TMP instead of changing it
Here are the highlights of this release:
- Feature variants AKA "optional dependencies"
- Type-safe accessors in Kotlin precompiled script plugins
- Gradle Module Metadata 1.0
For more details see https://docs.gradle.org/5.3/release-notes.html
This commit adds a variant for every official distribution that omits
the bundled jdk. The "no-jdk" naming is conveyed through the package
classifier, alongside the platform. Package tests are also added for
each new distribution.
This breaks on windows where TMP dir default to C:\Windows and startup
fails with a permission error.
I tried to create a tmp dir and pass in `TMP` env, but it lead to a
class not found error, and since testclusers is already independent of
the calling environment I stopped there.
The changes in #39732 mean that nodes in the IntegTest clusters will
now run with whichever java version is defined as `runtime.java` and
not JAVA_HOME anymore.
This means that these nodes will also run in JVM with fips approved
mode enabled and as such, need to have access to the password for the
BCFKS keystore that is used as the default keystore/truststore.
This change sets the two necessary system properties.
Resolves#39855
* Bundle java in distributions
Setting up a jdk is currently a required external step when installing
elasticsearch. This is particularly problematic for the rpm/deb packages
as installing a jdk in the same package installation command does not
guarantee any order, so must be done in separate steps. Additionally,
JAVA_HOME must be set and often causes problems in selecting a correct
jdk when, for example, the system java is an older unsupported version.
This commit bundles platform specific openjdks into each distribution.
In addition to eliminating the issues above, it also presents future
possible improvements like using jlink to build jdk images only
containing modules that elasticsearch uses.
closes#31845
This commit introduces the forget follower API. This API is needed in cases that
unfollowing a following index fails to remove the shard history retention leases
on the leader index. This can happen explicitly through user action, or
implicitly through an index managed by ILM. When this occurs, history will be
retained longer than necessary. While the retention lease will eventually
expire, it can be expensive to allow history to persist for that long, and also
prevent ILM from performing actions like shrink on the leader index. As such, we
introduce an API to allow for manual removal of the shard history retention
leases in this case.
* Back port build changes from #39102
This back-ports how versions are determined and bwc test are set up from
#39102 without enabling the bwc from current version tests so it's
easier/possible to backmerge future buld changes.
It's expected that the tets are lacking many of the required fixes in
this version to enable them.
* methods to run bin script
* Add support for specifying and installing plugins
* Add OS specific distirbution support
* Add test to verify plugin installed
* Remove use of Gradle internal OperatingSystem
* Un-mute and fix BuildExamplePluginsIT
There doesn't seem to be anything wrong with the test iteself.
I think the failure were CI performance related, but while it was muted,
some failures managed to sneak in.
Closes#38784
* PR review
When test clusters are stood up, one of the steps in the wait task is to wait for
ports files to appear. An exception throw was added if this were to time out
instead of failing with no information, but the exception text uses a missing
variable which further obfuscates the problem.
Backports #39321
Backport of #39350
Contains the following:
* LUCENE-8635: Move terms dictionary off-heap for non-primary-key fields in `MMapDirectory`
* LUCENE-8292: `TermsEnum` is fully abstract
* LUCENE-8679: Return WITHIN in `EdgeTree#relateTriangle` only when polygon and triangle share one edge
* LUCENE-8676: Nori tokenizer deals correctly with large buffers
* LUCENE-8697: `GraphTokenStreamFiniteStrings` better handles side paths with gaps
* LUCENE-8664: Add `equals` and `hashCode` to `TotalHits`
* LUCENE-8660: `TopDocsCollector` returns accurate hit counts if the total equals the threshold
* LUCENE-8654: `Polygon2D#relateTriangle` fix for when the polygon is inside the triangle
* LUCENE-8645: `Intervals#fixField` can merge intervals from different fields
* LUCENE-8585: Create jump-tables for DocValues at index time
Packaging tests did not honor bwc tests being off.
This was also the reason for which we were building the BWC versinons
even if the tests are off, so this closes#35347.
This fixes a bug in the sensing of the current OS family in the test cluster
formation code. Previously all builds would assume every environment
was windows and would jump to using the windows zip build. This fixes
the OS sensing code as well as updates some tests to account for
different build flavors.
Backport of #38457
This commit fixes a bug which resulted in every RandomizedTestingTask
generating its own unique test seed rather than using the global test
seed generated by the the RandomizedTestingPlugin.
The issue didn't affect build invocations which explicitly ran with
-Dtest.seed. In those cases, the Ant junit task correctly uses the
global seed.
Since the Ant random testing target looks for an Ant project property
for determining the existing seed we now explicitly set this inside
RandomizedTestingPlugin. It just so happens that, incidentally, Ant will
inherit system properties, thus wy the -Dtest.seed mechanism continued
to work.
In the ClusterConfiguration class of the build source, there is an Ant waitfor block
that runs to ensure that the seed node's transport ports file is created before
trying to read it. If the wait times out, the file read fails with not much helpful info.
This just adds a timeout property to the waitfor block and throws a descriptive
exception instead.
Backports #37574
This commit moves validation logic for ensuring our testclusters
configuration doesn't contain unexpected artifacts into the plugin
itself. This change allows us to remove the custom copy task
implementation altogether.
Additionally, the error message has been improved to display component
ids in addition to the artifacts to make it easier to figure out what
actual dependency is at fault.
Handle the case of `Description` being null which is a valid case as
described in the `HeartBeatEvent`'s javadoc, which previously resulted
in exceptions that "pollute" the build output.
Follows: #28563
Backport: #38799
Recently we changed where we source released artifacts for usage in
backwards compatibility tests. We now source these from
artifacts.elastic.co. To avoid polluting the download stats from builds,
we want to add the X-Elastic-No-KPI header to requests from
artifacts.elastic.co. To do this, we hack the Ivy feature of custom HTTP
header credentials and specify our desired headers.
When we are preparing to release a major version the rules around
"unreleased" versions and branches get a bit more complex.
This change implements the following rules:
- If the tip version on the previous major is a .0 (e.g. 6.7.0) then
the tip of the minor before that (e.g. 6.6.1) must be unreleased.
(This is because 6.7.0 would be "staged" in preparation for release,
but 6.6.1 would be open for bug fixes on the release 6.6.x line)
(in VersionCollection & VersionUtils)
- The "major.x" branch (if it exists) will always point to the latest
minor in that series. Anything that is not the latest minor, must
therefore be on a the "major.minor" branch
For example, if v7.1.0 exists then the "7.x" branch must be 7.1.0,
and 7.0.0 must be on the "7.0" branch
(in VersionCollection)
This commit adds the 7.1 version constant to the 7.x branch.

Renames the following settings to remove the mention of `zen` in their names:
- `discovery.zen.hosts_provider` -> `discovery.seed_providers`
- `discovery.zen.ping.unicast.concurrent_connects` -> `discovery.seed_resolver.max_concurrent_resolvers`
- `discovery.zen.ping.unicast.hosts.resolve_timeout` -> `discovery.seed_resolver.timeout`
- `discovery.zen.ping.unicast.hosts` -> `discovery.seed_addresses`
The apache commons http client implementations recently released
versions that solve TLS compatibility issues with the new TLS engine
that supports TLSv1.3 with JDK 11. This change updates our code to
use these versions since JDK 11 is a supported JDK and we should
allow the use of TLSv1.3.
Today we pass `discovery.zen.minimum_master_nodes` to nodes started up in
tests, but for 7.x nodes this setting is not required as it has no effect.
This commit removes this setting so that nodes are started with more realistic
configurations, and deprecates it.
The script is used to create a cache on ephemeral CI workers.
Changes:
- create and use a `pullFixture` task that always exists regardless
of docker support
- wire dependencies correctly so any pre fixture setup runs for pull
as well
- set up java env vars so bwc versions can build
This commit adds classifiers to the distributions indicating the
OS (for archives) and platform. The current OSes are for windows, darwin (ie
macos) and linux. This change will allow future OS/architecture specific
changes to the distributions. Note the docs using distribution links
have been updated, but will be reworked in a followup to make OS
specific instructions for the archives.
This commit fixes the distribution flavor passed to the docs tests to be
the same as the distribution. These two values are now in sync (either
oss or default) for the docs tests.
- Cluster logs are only indented as node name is already in the logs
- silence logging on shutdown
- have fully qualified name as node and cluster name
Reverts #36259 in part to make randomized test fail if no tests are ran.
This is useful when filtering tests as it's easy to make a typo and
think the test ran trough successfully.
* Testing conventions now checks for tests in main
This is the last outstanding feature of the old NamingConventionsTask,
so time to remove it.
* PR review
This change adds a docker compose configuration that's used with
the `elasticsearch.test.fixtures` plugin to start up the image
and check that the TCP ports are up.
We can build on this to add other checks for culster health,
run REST tests, etc.
We can add multiple containers and configurations to the compose
file (e.x. test different env vars) and form clusters.
Currently integration tests which use either bwc snapshot versions or
the current version of elasticsearch depend on project substitutions to
link to the build of those artifacts. Likewise, vagrant tests use
dependency substitutions to get to bwc snapshots of rpm and debs.
This commit changes those to depend on the relevant project/configuration
and removes the dependency substitutions for distributions we do not
publish.
The example plugins are currently built within the build-tools integ
tests as a means to ensure the gradle plugin works for external plugin
builds. These tests generate a dummy build.gradle, and a dummy local
maven repository to find the local builds dependencies in. Currently
that build-tools dependency uses "+" as the version. However, this
allows gradle to find the "latest" version, and unfortunately gradle has
its own plugin repository which is apparently connected to jcenter. This
recently triggered a flood of CI failures when jcenter suddenly pulled
alpha2, and all builds started trying to use that instead of the locally
built build-tools. This commit uses the explicit version of build-tools
that was build locally, which will cause resolution to stop when the
local repo is first checked.
The integ tests currently use the raw zip project name as the
distribution type. This commit simplifies this specification to be
"default" or "oss". Whether zip or tar is used should be an internal
implementation detail of the integ test setup, which can (in the future)
be platform specific.
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.
Currently bwc builds require different java home environment variables
depending on the version of elasticsearch being built. The java home
version checks are run at the end of gradle configuration, when the task
graph is ready. However, we do not know which versions are needed for
bwc builds until execution time, when we have finished checking out the
version of elasticsearch to be built. This commit accounts for late java
home checks, checking immediately instead of delaying the check.
closes#37586
This is a continuation of #28667 and has as goal to convert all executors to propagate errors to the
uncaught exception handler. Notable missing ones were the direct executor and the scheduler. This
commit also makes it the property of the executor, not the runnable, to ensure this property. A big
part of this commit also consists of vastly improving the test coverage in this area.
This commit moves log statements related to classification of naming
convention checks for tests to debug level. At info level they emit an
enormous amount of output in CI, while these are not generally useful
for debugging normal build failures.
Commit #36786 updated docs and strings to reference transport.port instead of
transport.tcp.port. However, this breaks backwards compatibility tests
as the tests rely on string configurations and transport.port does not
exist prior to 6.6. This commit reverts the places were we reference
transport.tcp.port for tests. This work will need to be reintroduced in
a backwards compatible way.
Lucene 7.6 uses a smaller encoding for LatLonShape. This commit forks the LatLonShape classes to Elasticsearch's local lucene package. These classes will be removed on the release of Lucene 7.6.
This is related to #36652. In 7.0 we plan to deprecate a number of
settings that make reference to the concept of a tcp transport. We
mostly just have a single transport type now (based on tcp). Settings
should only reference tcp if they are referring to socket options. This
commit updates the settings in the docs. And removes string usages of
the old settings. Additionally it adds a missing remote compress setting
to the docs.
Includes the following:
* Reversion of doc-values changes in LUCENE-8374; we are interested in seeing if this
has an effect on benchmarks for node-stats and index-stats
* More improvements to docvalues updates
- fix up to date checks to ignore elasticsearch jars. We were not scanning them but these still triggered a rebuild.
- add tests to assert correct behavior and up to date checks.
- make the task less verbose with `-i` and include the output only on errors.
* Upgrae plugin to latest and expose udp
* Explicit check for windows
* Rename the properties for the port numbers
* Tasks for pre and pos container actions
Our Docker build uses a multi-stage Docker build. This requires Docker
version 17.05 or greater. Without an explicit check here, the build
fails in a mysterious way such as "invalid reference format" that is
hard to track down (Google searches for "Docker invalid reference
format" do not turn up anything useful). This commit refactors our
existing Docker checks, and adds a new one for the minimum Docker
version.
This commit changes the Docker assemble tasks so that they attempt to
build Docker if the Docker binaries exist, of if build.docker is set to
true. If the Docker binaries do not exist, or if build.docker is set to
false, then no attempt is made to build the Docker images.
Moves all remaining (rolling-upgrade and mixed-version) REST tests to use Zen2. To avoid adding
extra configuration, it relies on Zen2 being set as the default discovery type. This required a few
smaller changes in other tests. I've removed AzureMinimumMasterNodesTests which tests Zen1
functionality and dates from a time where host providers were not configurable and each cloud
plugin had its own discovery.type, subclassing the ZenDiscovery class. I've also adapted a few tests
which were unnecessarily adding addTestZenDiscovery = false for the same legacy reasons. Finally,
this also moves the unconfigured-node-name REST test to Zen2, testing the auto-bootstrapping
functionality in development mode when no discovery configuration is provided.
Closes#34820
With this change we allow for no tests being ran in randomized testing
task, and forbid empty testing tasks from the testing conventions task.
We will no longer have to disable the task if all tests are muted.
* Improve logged exec output readability
- Split error and out streams and log them separately
- Log everything in a single call to prevent interference from
other log messages
Includes:
LUCENE-8594: DV update are broken for updates on new field
LUCENE-8590: Optimize DocValues update datastructures
LUCENE-8593: Specialize single value numeric DV updates
Relates #36286
This commit moves back to use explicit dependsOn for test tasks on
check. Not all tasks extending RandomizedTestingTask should be run by
check directly.
This commit fixes an oops when pushing a change to add the building of
the Docker images. A change that was made for testing was accidentally
left behind. This commit addresses that.
This commit introduces the building of the Docker images as bonafide
packaging formats alongside our existing archive and packaging
distributions. This build is migrated from a dedicated repository, and
converted to Gradle in the process.
Currently we use Math.random() in a few places in the tests which makes these
tests not reproducable with the random seed mechanism that comes with
ESTestCase. The change removes those instances.
Closes#35435
- make it easier to add additional testing tasks with the proper configuration and add some where they were missing.
- mute or fix failing tests
- add a check as part of testing conventions to find classes not included in any testing task.
The logic in the dockerComposeSupported method currently returns false
even when docker and docker compose are available on the build machine.
This change updates the check to see if docker compose is available in
one of the two paths and allows the `tests.fixture.enabled` property to
disable the tests even if docker compose is available.
This commit upgrades netty. This will close#35360. Netty started
throwing an IllegalArgumentException if a CompositeByteBuf is
created with < 2 components. Netty4Utils was updated to reflect this
change.
This commit removes padding from the java version in the output of
compiler/runtime/gradle java versions. This value is only ever 1 or 2
digits, and the later information (hotspot/jvm vendor info) is separated
by the java home path from the other versions, so there isn't a visual
reason for needing exact vertical alignment.
Some times the test fixtures plugin did not correctly disable tasks
from the build plugin as it should.
The plugin manager and tasks both use domain name collections so
the previus conde should have worked.
I did not have trime to track it down, but suspect there's some race
condition in Gradle causing this. The plugin manager is still incubating.
Since the tasks are on the cp even if the plugin is not applyed, we
don't really need to involve the plugin at all.
Closes#36041
Our `REPRODUCE WITH` line wasn't working for tests with `(` or `)` in
the method name. This isn't super common, but happens sometimes for our
yml based rest tests. This is because randomized runner's globbing
mechanism dind't escape `(` or `)`. I filed this upstream at
https://github.com/randomizedtesting/randomizedtesting/issues/271
and Dawid kindly fixed the issue. This upgrades to pick up the fix.
Closes#35692
In #35259 we switched the default number of VMs to fork for unit tests to
the number of physical CPU cores. But because we could only get an accurate
count on machines with a normal `/proc` filesystem, macOS machine did not
pick up the new default. Given that macOS is a huge portion of developer
machines, we'd like to get the right default there. This does that.
It also moves the default-finding process from happening once per testing
task to happening once at startup. This seems like a good choice in general,
but a very good choice for macOS because we have to run a command to list
the count.
This inserts newlines in order to reduce line lengths in the
o.e.action.admin.cluster package to 140 characters or less. This
also remves the checkstyle suppressions for affected files.
Relates #34884, #34923
- 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.
* Swithc to jcenter
Jcenter suposedly operates on a CDN.
It should be faster and more reliable.
It's the default in Andorid Studio currently
( it switched from mavenCentral ).
This change is safe because jcenter is a superset of mavenCentral.
* update comment
* DISCOVERY: 0s Initial State Timeout in Tests
* Don't wait for initial state even with a single node, otherwise the loop writing the discovery file causes that single node to wait
for its own transport.ports file for 30s.
* Closes#35456
* DISCOVERY: Fix RollingUpgradeTests
* Don't manually manage min master nodes if not necessary
* Remove some dead code
* Allow for manually supplying list of seed nodes
* Closes#35178
With this change, `Version` no longer carries information about the qualifier,
we still need a way to show the "display version" that does have both
qualifier and snapshot. This is now stored by the build and red from `META-INF`.
* Add missing up-to-date configuration
The source properties file and the dynamic elasticsearch version
(set based on properties ) were missing from task outputs leading
to the task being incorrectly considered up to date.
