Adds an assertion that checks that the same shard with same id is not added to same node. Previously we would just silently ignore the second shard being added.
This commit enables real BWC testing against a 5.1 snapshot. All
REST tests plus rolling upgrade test now run against a mixed version
cross major version cluster.
JDK9 removed pathname canonicalization when constructing FilePermission objects, which breaks some of the FilePermissions added by
Elasticsearch. This commit adds the system property jdk.io.permissionsUseCanonicalPath which makes JDK9 behave like JDK8 w.r.t. FilePermissions (see
https://github.com/elastic/elasticsearch/issues/21534).
This commit changes the current :elactisearch:qa:vagrant build file and transforms it into a Gradle plugin in order to reuse it in other projects.
Most of the code from the build.gradle file has been moved into the VagrantTestPlugin class. To avoid duplicated VMs when running vagrant tests, the Gradle plugin sets the following environment variables before running vagrant commands:
VAGRANT_CWD: absolute path to the folder that contains the Vagrantfile
VAGRANT_PROJECT_DIR: absolute path to the Gradle project that use the VagrantTestPlugin
The VAGRANT_PROJECT_DIR is used to share project folders and files with the vagrant VM. These folders and files are exported when running the task `gradle vagrantSetUp` which:
- collects all project archives dependencies and copies them into `${project.buildDir}/bats/archives`
- copy all project bats testing files from 'src/test/resources/packaging/tests' into `${project.buildDir}/bats/tests`
- copy all project bats utils files from 'src/test/resources/packaging/utils' into `${project.buildDir}/bats/utils`
It is also possible to inherit and grab the archives/tests/utils files from project dependencies using the plugin configuration:
apply plugin: 'elasticsearch.vagrant'
esvagrant {
inheritTestUtils true|false
inheritTestArchives true|false
inheritTests true|false
}
dependencies {
// Inherit Bats test utils from :qa:vagrant project
bats project(path: ':qa:vagrant', configuration: 'bats')
}
The folders `${project.buildDir}/bats/archives`, `${project.buildDir}/bats/tests` and `${project.buildDir}/bats/utils` are then exported to the vagrant VMs and mapped to the BATS_ARCHIVES, BATS_TESTS and BATS_UTILS environnement variables.
The following Gradle tasks have also be renamed:
* gradle vagrantSetUp
This task copies all the necessary files to the project build directory (was `prepareTestRoot`)
* gradle vagrantSmokeTest
This task starts the VMs and echoes a "Hello world" within each VM (was: `smokeTest`)

Hack around cluster service and logging race

When a cluster update task executes, there can be log messages after the
update task has finished processing and the new cluster state becomes
visible. The visibility of the cluster state allows the test thread in
UpdateSettingsIT#testUpdateAutoThrottleSettings and
UpdateSettingsiT#testUpdateMergeMaxThreadCount to proceed. The test
thread will remove and stop a mock appender setup at the beginning of
the test. The log messages in the cluster state update task that occur
after processing has finished can race with the removal of the
appender. Log4j will grab a reference to the appenders when processing
these log messages, and this races with the removal and stopping of the
appenders. If Log4j grabs a reference to the appenders before the mock
appender has been removed, and the test thread subsequently removes and
stops the appender before Log4j has appended the log message, Log4j will
get angry that we are appending to a stopped appender, causing the test
to fail. This commit addresses this race by waiting for the cluster
state update task to have finished processing before freeing the test
thread to make its assertions and finally remove and stop the
appender. Yes, this is a hack.

When a node closes, we shutdown logging as the last statement. This
statement must be last lest any subsequent attempts to log will blow up
by running into security permissions. Yet, in the case of a tribe node
this isn't enough. The first internal tribe node to close will shutdown
logging, and subsequent node closes will blow up with the aforementioned
problem. This commit migrate the Log4j shutdown to occur as part of the
shutdown hook that closes the node, after all nodes have
closed. Consequently, we can remove a hack in the test infrastructure to
prevent Log4j shutdowns when internal test nodes close and instead just
register a single shutdown hook that runs when the test JVM exits.

This adds support to painless for decimal constants with trailing `d` or
`D` to make it compatible with Java. It already supported integer
constants with a trailing `d` or `D` but this adds tests for it.
Closes#21116
In painless we prefer explicit types over implicit ones whereas
groovy is the other way around. Take this groovy code:
```
> 86400000.class
java.lang.Integer
> 864000000000.class
java.lang.Long
```
Painless accepts `86400000` just fine because that is a valid `int`
in the jvm. It rejects `864000000000` as an invlid `int` constant
because, in painless as in java, `long` constants always end in `L`
or `l`.
To ease the transition from groovy to painless, this changes the
compilation error returned from these invalid constants from:
```
Invalid int constant [864000000000].
```
to
```
Invalid int constant [864000000000]. If you want a long constant then change it to [864000000000L].
```

On some systems these utilities are in /usr/lib/systemd/systemd-sysctl
and /usr/sbin/sysctl, and on others the /usr is dropped. This commit
accounts for that fact.
Under some rare conditions search cancellation response might not fully clean scroll context. For now this commit adds the cleaning operation to the test, and we will address the root cause in https://github.com/elastic/elasticsearch/issues/21511

Task cancellation command should wait for all child nodes to receive cancellation request before returning
We have an assertion in the engine regarding the initial state of a
sequence number before an indexing operation. This assertion is too
loose, it catches operations during recovery from old indices where
sequence numbers do not even exist. This commit tightens these
assertions to not catch such operations and enables us to reenable some
tests.

Our docs claim that we set vm.max_map_count automatically. This is not
quite the case. The story is that on SysV init we set vm.max_map_count
each time the service starts, which is good. On systemd, we create a
sysctl.d conf file that sets vm.map_max_count, but this is only
meaningful if the system is rebooted after package install. This commit
modifies the post-install script so that we run systemd-sysctl so that
the vm.max_map_count change occurs after package install without a
reboot.

so that we are more likely to trigger I/O exceptions on writing the control files during the
finalize phase of snapshotting (with the aim of triggering an I/O failure when writing pending-index-*).
This commit sets the mock appender in UpdateSettingsIT to not ignore
exceptions. This means that when an exception is hit, we will see an
actual stack trace that could be useful in debugging a non-reproducible
test failure.

Document _reindex with random_score
[TEST] Makes the snapshot throttling test go much faster. Before,
the snapshot throttling test would throttle at a rate of 0.5 kb per
second, even though it would snapshot/restore about 25 kb of data.
This commit increases the throttling rate to 10kb per second, so
we still test the throttling mechanism while speeding up the test from
taking 30 plus seconds down to 2 seconds or less.
0219a211d3 added support for templates
to have multiple patterns and renamed `template` to `index_patterns`.
This adds the breaking changes docs for that.
Each node checks on every cluster state update if there are shards that it can possibly delete from its disk. It decides this by doing a file-system lookup for each shard id that is fully allocated in the cluster. With lots of shards, this amounts to lots of Files.exists() checks, considerably slowing down cluster state updates. This commit adds a caching layer so that the Files.exists() checks can be skipped if not needed.

Currently the task cancellation command returns as soon as the top-level parent child is marked as cancelled. This create race conditions in tests where child tasks on other nodes may continue to run for some time after the main task is cancelled. This commit fixes this situation making task cancellation command to wait until it got propagated to all nodes that have child tasks.
Closes#21126
ShardActiveResponseHandler doesn't need to hold to an entire cluster state since it only needs to know the cluster state version. It seems that on overloaded systems where nodes are unresponsive holding onto a lot of different cluster states can make the situation worse.
Closes#21394
Ensures pending index-* blobs are deleted when snapshotting. The
index-* blobs are generational files that maintain the snapshots
in the repository. To write these atomically, we first write a
`pending-index-*` blob, then move it to `index-*`, which also deletes
`pending-index-*` in case its not a file-system level move (e.g.
S3 repositories) . For example, to write the 5th generation of the
index blob for the repository, we would first write the bytes to
`pending-index-5` and then move `pending-index-5` to `index-5`. It is
possible that we fail after writing `pending-index-5`, but before
moving it to `index-5` or deleting `pending-index-5`. In this case,
we will have a dangling `pending-index-5` blob laying around. Since
snapshot #5 would have failed, the next snapshot assumes a generation
number of 5, so it tries to write to `index-5`, which first tries to
write to `pending-index-5` before moving the blob to `index-5`. Since
`pending-index-5` is leftover from the previous failure, the snapshot
fails as it cannot overwrite this blob.
This commit solves the problem by first, adding a UUID to the
`pending-index-*` blobs, and secondly, strengthen the logic around
failure to write the `index-*` generational blob to ensure pending
files are deleted on cleanup.
Closes#21462
This change was reverted after it caused random test failures. This was
due to a copy/paste error in the original PR which caused the mock
version of ClusterInfoService to be used whenever the mock *ZenPing* was
used, and the real ClusterInfoService to be used when MockZenPing was
not used.
