This change updates tests that use a CountDownLatch to synchronize the
running of threads when testing concurrent operations so that we ensure
the thread has been fully created and run by the scheduler. Previously,
these tests used a latch with a value of 1 and the test thread counted
down while the threads performing concurrent operations just waited.
This change updates the value of the latch to be 1 + the number of
threads. Each thread counts down and then waits. This means that each
thread has been constructed and has started running. All threads will
have a common start point now.
Today we do not expose the cluster UUID in any logs by default, but it would be
useful to see it. For instance if a user starts multiple nodes as separate
clusters then they will silently remain as separate clusters even if they are
subsequently reconfigured to look like a single cluster. This change logs the
committed cluster UUID the first time the node encounters it.
* Switch to using a list instead of a Set for the filters, so that the
order of these filters is kept.
(cherry picked from commit 74a743829799b64971e0ac5ae265f43f6c14e074)
The `toStepKeys()` method was only called in its own test case. The real
list of StepKeys that's used in action execution is generated from the
list of actual step objects returned by `toSteps()`.
This commit removes that method.
If remote recovery copies an index commit which has gaps in sequence
numbers to a follower; then these assertions (introduced in #40823)
don't hold for follower replicas.

The elasticsearch-cli helper script does not use the tempdir created by
elasticsearch-env, yet the env script still creates it. This can lead to
lots of temp directories being created when running cli scripts in an
automated fashion. This commit passes a fake tmpdir to the env script to
avoid creation.

On debian-8, when trying to apt-get update, it currently (sometimes)
fails on one of the extra repositories. This failure to update causes
keys to not be updated, which later can cause some packages to not
install due to lack of key verification. This commit removes the
troublesome repository before we attemp to update.

This commit adds deletion of the bin directory to postrm cleanup. While
the package's bin files are cleaned up by the package manager, plugins
may have created subdirectories under bin. We already cleanup plugins,
but not the extra bin dirs their installation created.

Currently IndexAnalyzers keeps the three default as separate class members
although they should refer to the same analyzers held in the additional
analyzers map under the default names. This assumption should be made more
explicit by keeping all analyzers in the map. This change adapts the constructor
to check all the default entries are there and the getters to reach into the map
with the default names when needed.
The changes in #39317 brought to light some concurrency issues in the
close method of Recyclers as we do not wait for threads running in the
threadpool to be finished prior to the closing of the PageCacheRecycler
and the Recyclers that are used internally. #41695 was opened to
address the concurrent close issues but upon review, the closing of
these classes is not really needed as the instances should be become
available for garbage collection once there is no longer a reference to
the closed node.
Closes#41683
We have a number of places in analysis-handling code where we check
if a field type is a keyword field, and if so then extract the normalizer rather
than pulling the index-time analyzer. However, a keyword normalizer is
really just a special case of an analyzer, so we should be able to simplify this
by setting the normalizer as the index-time analyzer at construction time.
This commit slightly reworks the recommendations in the docs about setting the
heap size:
* the "rules of thumb" are actually instructions that should be followed
* the reason for setting `Xmx` to 50% of the heap size is more subtle than just
leaving space for the filesystem cache
* it is normal to see Elasticsearch using more memory than `Xmx`
* replace `cutoff` and `limit` with `threshold` since all three terms are used
interchangeably
* since we recommend setting `Xmx` equal to `Xms`, avoid talking about setting
`Xmx` in isolation

* Fix slow sync test clustres artifacts task
The task was mistakenly adding a combinational explosion of task
actions all doing the same thing.
With this PR this is fixed and each version - distribution pair is only
extracted once.
I appologieze for the SSD wear.
* Look for configurations on the root project
* Add dependency on configurations
* This should be a `copy` so we don't blow away all the other distros
* Don't copy example plugin build directory in integration tests
* This test was resulting in a `PARTIAL` instead of a `SUCCESS` state for
the case of closing an index during snapshotting on 7.x
* The reason for this is the changed default behaviour regarding
waiting for active shards between 8.0 and 7.x
* Fixed by adjusting the waiting behaviour on the close index request
in the test
* Closes#39828
* When close becomes true while the management pool is shut down, we run
into an unhandled `EsRejectedExecutionException` that fails tests
* Found this while trying to reproduce #32506
* Running the IndexStatsIT in a loop is a way of reproducing this
This commit disables rhel 8 from being tested in vagrant packaging
tests. The vagrant image we use is beta release, but RHEL 8 was just
released, which has caused the package mirrors for the beta to stop
working.
This commit reworks the tests for jdk download to test the old and new
url pattern from oracle. Additionally it limits to one repository
created per version, based on the old or new pattern, and restricts
other repositories from trying to resolve jdks.

Previously, TransportSingleShardAction required constructing a new
empty response object. This response object's Streamable readFrom
was used. As part of the migration to Writeable, the interface here
was updated to leverage Writeable.Reader.
relates to #34389.
The close method in Node uses a StopWatch to time to closing of
various services. However, the call to log the timing was made before
any of the services had been closed and therefore no timing would be
printed out. This change moves the timing log call to be a closeable
that is the last item closed.
This change makes the default seed address tests account for the lack
of an IPv6 network. By default docker containers only run with IPv4 and
these tests fail in a vanilla installation of elasticsearch-ci. To
resolve this we only expect IPv6 seed addresses if IPv6 is available.

Java 8 presents the JVM options slightly differently when displaying via
-XX:+PrintFlagsFinal. This commit adapts the JVM options parser for this
possibility.

If the max doc in the index is greater than the minimum total term frequency
among the requested fields we need to adjust max doc to be equal to the min ttf.
This was removed by mistake when fixing #41125.

This processor uses the lucene HTMLStripCharFilter class to remove HTML
entities from a field. This adds to the char filter, so that there is
possibility to store the stripped version as well.
Note, that the characeter filter replaces tags with a newline, so that
the produced HTML will look slightly different than the incoming HTML
with regards to newlines.
This commit removes manual parsing of JVM options when calculating
ergonomics. This is to avoid a situation that we parse values
differently than the JVM would. In fact, we already have a bug along
these lines today. It is possible to start the JVM with the same flag
multiple times on the command line. In this case, the last value
wins. For example, -Xmx1g -Xmx2g would start the JVM with a heap size of
two gigabytes. Our JVM ergonomics ignores this possibility and instead
the first value is winning!
Our strategy to avoid manual parsing of the JVM options is to start the
Java command line parser (without actually starting a JVM) by invoking
java with the same command line flags as presented and request that the
JVM tell us what values it would start with. This ensures that we have
the correct values when making ergonomic decisions.
Moreover, our strategy also is ignoring ES_JAVA_OPTS which could
override the heap size as well leading to incorrect ergonomic
choices. This commit address this issue too.
The ReadOnlyEngine wraps its reader with a SoftDeletesDirectoryReaderWrapper if soft deletes
are enabled. However the wrapping is done on top of the ElasticsearchDirectoryReader and that
trips assertion later on since the cache key of these directories are different. This commit
changes the order of the wrapping to put the ElasticsearchDirectoryReader first in order to
ensure that it is always retrieved first when we unwrap the directory.
Closes#41795
The deb package has been updated several times in the past to contain
overrides in order to pass lintian inspection. However, there have never
been any tests to ensure we do not fallback to failure. This commit
updates the overrides file given things that have changed since 2.x like
adding ML and bundling the jdk.
