Our default pattern layout truncates log messages. This is to avoid
blowing disk space from excessively log messages, which can happen if a
message contains a mapping or an large query. Yet, we trunacte from the
beginning which is probably where the most germane information is. This
commit modifies the default pattern layout to trunacte from the end.

Adds a version constant for it, bwc indices, and a vagrant upgrade-from
version. Also bumps the "upgrade from" version for the backwards-5.0
test and adds `skip`s for tests that don't fail against 5.0 so we skip
them during the backwards testing.
Finally, this skips the "Shrink index via API" test because it fails
consistently for me. Inconsistently for CI, but consistently for me.
I'll work on making it consistent tomorrow.
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.
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.

Given that the default is now 1, the comment in the config file was outdated. Also considering that the default value is production ready, we shouldn't list it among the values that need attention when going to production.

The environment variable ES_JVM_OPTIONS allows end-users to specify a
custom location for the jvm.options file. Unfortunately, this
environment variable is not exported from the SysV init scripts. This
commit addresses this issue, and includes a test that ES_JVM_OPTIONS and
ES_JAVA_OPTS work for the SysV init packages.

All plugins currently have their own licenses dir for the
dependencyLicenses task, but core disables this and has the check inside
distribution. This may have been better for maven, but for
gradle it makes more sense to just use the dependencyLicenses task that
automatically exists inside :core, and remove the hacked up version that
is inside distribution.
At one point in the past when moving out the rest tests from core to
their own subproject, we had multiple test classes which evenly split up
the tests to run. However, we simplified this and went back to a single
test runner to have better reproduceability in tests. This change
removes the remnants of that multiplexing support.
On ubuntu 14.04, which uses upstart, where as our debian package uses
sysvinit, there is no stdout/stderr message printed when starting up,
because the start-stop-daemon swallows it.
As Elasticsearch is started to daemonize, we can remove the background
flag from the start-stop-daemon and thus see, if the system does not have
enough memory for starting up - something that happens often on VMs, since
Elasticsearch 5.0 uses 2gb by default instead of one.

Today when running gradle clean
:distribution:(integ-test-zip|tar|zip):assemble, the created archive
distribution will be missing the empty plugins directory. This is
because the empty plugins folder created in the build folder for the
copy spec task is created during configuration and then is later wiped
away by the clean task. This commit addresses this issue, by pushing
creation of the directory out of the configuration phase.

Today when installing Elasticsearch from an archive distribution (tar.gz
or zip), an empty plugins folder is not included. This means that if you
install Elasticsearch and immediately run elasticsearch-plugin list, you
will receive an error message about the plugins directory missing. While
the plugins directory would be created when starting Elasticsearch for
the first time, it would be better to just include an empty plugins
directory in the archive distributions. This commit makes this the
case. Note that the package distributions already include an empty
plugins folder.

When installing the Windows service, certain settings like the minimum

Lucene 6.3 is expected to be released in the next weeks so it'd be good to give

both Lucene and Elasticsearch are on the same version.
This commit fixes responses to HEAD requests so that the value of the
Content-Length is correct per the HTTP spec. Namely, the value of this
header should be equal to the Content-Length if the request were not a
HEAD request.
This commit also fixes a memory leak on HEAD requests to the main action
that arose from the bytes on a builder not being released due to them
being dropped on the floor to ensure that the response to the main
action did not have a body.

Before this commit `curl -XHEAD localhost:9200?pretty` would return

We have a "HUGE HACK" that allows us to publish zip artifacts to
Sonatype's OSS repository without javadoc and source jars. We don't
include those jars because the zip is just a repackaging of the
core and module jars for which we already publish the javadoc and
source jars. So we have a hack to publish the zip artifact when the
pom says the project is of type 'pom'.
I'm not sure why we need this pom instead of the pom generated by
nebula, but if we are going to have it then we need to populate it
with appropriate stuff like project name, description, and url.
* Build: Remove old maven deploy support
This change removes the old maven deploy that we have in parallel to
maven-publish, and makes maven-publish fully work with publishing to
maven local. Using `gradle publishToMavenLocal` should be used to
publish to .m2.
Note that there is an unfortunate hack that means for
zip artifacts we must first create/publish a dummy pom file, and then
follow that with the real pom file. It would be nice to have the pom
file contains packaging=zip, but maven central then requires sources and
javadocs. But our zips are really just attached artifacts, so we already
set the packaging type to pom for our zip files. This change just works
around a limitation of the underlying maven publishing library which
silently skips attached artifacts when the packaging type is set to pom.

* Remove unnecessary extra spacing
Currently we always pass -E to the the plugin cli with the conf dir, but
this causes a very confusing error message when not giving a specific
command to the plugin cli. This change makes path.conf pass just like
path.home. These are special settings, so passing via sysprops is the
right thing to do (it is all about how we pass between shell and java
cli).

When uninstalling or upgrading elasticsearch using the RPM package some empty directories remain on the filesystem:
/usr/share/elasticsearch/bin
/usr/share/elasticsearch/lib
/usr/share/elasticsearch/modules
/usr/share/elasticsearch/modules/foo
Having empty directories in modules can prevent elasticsearch to start after an upgrade: the plugins service expects to find a plugin-descriptor.properties file in every sub directory of modules.
This PR cleans things a bit so that these empty directories are removed on upgrade/removal like it was in 2.x.
When upgrading elasticsearch using the RPM package, the scripts directory is removed if it's empty but it won't be recreated by the upgraded package. But after that the service won't start because the scripts dir is missing.
This commit modifies the logger names within Elasticsearch to be the
fully-qualified class name as opposed removing the org.elasticsearch
prefix and dropping the class name. This change separates the root
logger from the Elasticsearch loggers (they were equated from the
removal of the org.elasticsearch prefix) and enables log levels to be
set at the class level (instead of the package level).
Relates #20457
Today we add a prefix when logging within Elasticsearch. This prefix
contains the node name, and index and shard-level components if
appropriate.
Due to some implementation details with Log4j 2 , this does not work for
integration tests; instead what we see is the node name for the last
node to startup. The implementation detail here is that Log4j 2 there is
only one logger for a name, message factory pair, and the key derived
from the message factory is the class name of the message factory. So,
when the last node starts up and starts setting prefixes on its message
factories, it will impact the loggers for the other nodes.
Additionally, the prefixes are lost when logging an exception. This is
due to another implementation detail in Log4j 2. Namely, since we log
exceptions using a parameterized message, Log4j 2 decides that that
means that we do not want to use the message factory that we have
provided (the prefix message factory) and so logs the exception without
the prefix.
This commit fixes both of these issues.

This commit adds a -q/--quiet option to Elasticsearch so that it does not log anything in the console and closes stdout & stderr streams. This is useful for SystemD to avoid duplicate logs in both journalctl and /var/log/elasticsearch/elasticsearch.log while still allows the JVM to print error messages in stdout/stderr if needed.

The Elasticsearch startup scripts contain checks for the presence of
support for environment variables that were removed in the 5.x
series. These checks warn the user and fail the script if any of the
unsupported environment variables are present. This was provided as
migration step from 2.x to 5.x so that we were not just silently
ignoring environment variables that were previously set. This commit
removes these checks, as upgrades from 2.x to 6.x are not supported.

Previous versions of Elasticsearch permitted unquoted JSON field names even though this is against the JSON spec. This leniency was disabled by default in the 5.x series of Elasticsearch but a backwards compatibility layer was added via a system property with the intention of removing this layer in 6.0.0. This commit removes this backwards compatibility layer.

Jython shades `jansi` into it's classpath without changing it's package or

The integ-test-zip distribution did not specify a value for
path.conf. As such, it picked up the default value of
/etc/elasticsearch. This means that on machines that have this
directory, integration tests could fail because they would try to pick
up configuration from that directory rather than from the home directory
of the exploded distribution. This commit fixes this issue by specifying
a value of path.conf for the integ-test-zip distribution.

The deprecation logger is an important way to make visible features of
Elasticsearch that are deprecated. Yet, the default logging makes the
log messages for the deprecation logger invisible. We want these log
messages to be visible, so the default logging for the deprecation
logger should enable these log messages. This commit changes the log
level of deprecation log message to warn, and configures the deprecation
logger so that these log messages are visible out of the box.

Netty replaces the backing set for the selector implementation. The

the setting in elasticsearch.yml, so that when a user uncomments
out a setting by just removing the #, the setting actually
takes effect. Before, it was very easy to uncomment out a

setting to not get picked up by Elasticsearch.

With the security permissions that we grant to Netty, Netty can not

tell Netty to not look for unsafe.

This makes it obvious that these tests are for running the client yaml

client against a running cluster we can't go on calling the shared

**the** rest tests.
