Tasks can be registered with a timeout, which runs as a task in a separate
threadpool. The idea is that the timeout runner cancels the main task when
the time is out, and the timeout runner is cancelled when the main task
starts executing. However, the following statement:
```java
timeoutFuture = timer.schedule(new Runnable() {
@Override
public void run() {
if (remove(TieBreakingPrioritizedRunnable.this)) {
runAndClean(timeoutCallback);
}
}
}, timeValue.nanos(), TimeUnit.NANOSECONDS);
```
is not atomic: the removal task is first started, and then the (volatile)
variable is assigned. As a consequence, there is a short window that allows
a timeout task to wait until the time is out even if the task is already
completed.
See http://build-us-00.elastic.co/job/es_core_17_centos/496/ for an example of
such a failure.
Previously only the first aggregation in a buckets_path was check to make sure the aggregation existed. Now the whole path is checked to ensure an aggregation exists at each element in the buckets_path
Closes#12360
Its not going to work: its blocked by security policy
and will just add a confusing SecurityException to the mix, and
bogusly give an exit status of 0 when in fact something bad happened.
Finally, if ES can't startup, it is a serious problem, there is
no sense in hiding the reason why: deliver the full stack trace.
The repository verification process should create a subdirectory to make sure we check permission of newly created directories in case elasticsearch processes on different nodes are running using different uids and creating blobs with incompatible permissions.
Closes#11611
Previously we issued a reroute when a node went over the high watermark
in order to move shards away from the node. This change tracks nodes
that have previously been over the high or low watermarks and issues a
reroute when the node goes back underneath the watermark.
This allows shards that may be unassigned to be assigned back to a node
that was previously over the low watermark but no longer is.
Resolves#12422
As windows has different line endings and this has
already been fixed by another test, the method has been
moved into CliToolTestCase.
In addition one test has been removed, as it was redundant.
In order to ensure, we have the same experience across operating systems
and shells, this commit uses the java CLI parser instead of the shell
getopt parsing to parse arguments.
This also allows for support for paths, which contain spaces.
Also commons-cli depdency was upgraded to 1.3.1 and tests have been added.
Changes
* new exit code, OK_AND_EXIT, allowing to tell the caller to exit, as everything
went as expected (e.g. when running a version output)
BWC breaking:
* execute() returns an ExitStatus instead of an integer, otherwise there is no
possibility to signal by a command, if the JVM should be exited after a run.
This affects plugins, that have command line tools
* -v used to be version, but is a verbose flag by default in the current CLI infra,
must be -V or --version now
* -X has been removed - the current implementation was useless anyway, as
it prefixed those properties with "es.". You should use
ES_JAVA_OPTS/JAVA_OPTS for JVM configuration
We have had lots of test failures due to Groovy scripts making an assertion
trip in
`sun.reflect.generics.reflectiveObjects.WildcardTypeImpl.getLowerBoundASTs`.
