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.
Relates #21123
Before this commit `curl -XHEAD localhost:9200?pretty` would return
`Content-Length: 1` and a body which is fairly upsetting to standards
compliant tools. Now it'll return `Content-Length: 0` with an empty
body like every other `HEAD` request.

This commit upgrades the Log4j 2 dependency to version 2.7 and removes
some hacks that we had in place to work around bugs in Log4j 2 version
2.6.2.
Relates #20805
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.
closes#17220
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.
Relates #20404
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.

-D parameters used to be allowed when starting elasticsearch scripts.
However, this was removed in #18207, but the elasticsearch-plugin.bat script
was forgotten. This change removes the -D handling.
Jython shades `jansi` into it's classpath without changing it's package or
anything like that. This causes attempts to load native code on windows which
blows up tests. This change adds `log4j.skipJansi=true` system property to our
tests as well as to the JVM properties we set.
This commit configures the deprecation logs to be size-limited to 1 GB,

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
value of doing this is questionable, and doing this requires permissions
that we are not going to grant. This commit explicitly disables this
optimization rather than relying on it failing due to lack of
permissions.

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 by just removing the #, leaving a single whitespace
character before the setting name, which would cause the
setting to not get picked up by Elasticsearch.

With the security permissions that we grant to Netty, Netty can not
access unsafe (because it relies on having the runtime permission
accessDeclaredMembers and the reflect permission
suppressAccessChecks). Instead, we should just explicitly tell Netty to
not use unsafe. This commit adds a flag to the default jvm.options to
tell Netty to not look for unsafe.

This makes it obvious that these tests are for running the client yaml
suites. Now that there are other ways of running tests using the REST
client against a running cluster we can't go on calling the shared
client yaml tests "REST tests". They are rest tests, but they aren't
**the** rest tests.
This adds the `bin/elasticsearch-translate` bin file that will be used

```

This adds a header that looks like `Location: /test/test/1` to the
response for the index/create/update API. The requirement for the header
comes from https://www.w3.org/Protocols/rfc2616/rfc2616-sec10.htmlhttps://tools.ietf.org/html/rfc7231#section-7.1.2 claims that relative
URIs are OK. So we use an absolute path which should resolve to the
appropriate location.

This makes large changes to our rest test infrastructure, allowing us
to write junit tests that test a running cluster via the rest client.
It does this by splitting ESRestTestCase into two classes:
* ESRestTestCase is the superclass of all tests that use the rest client
to interact with a running cluster.
* ESClientYamlSuiteTestCase is the superclass of all tests that use the
rest client to run the yaml tests. These tests are shared across all
official clients, thus the `ClientYamlSuite` part of the name.
Some tests still start http implicitly or miss configuring the transport clients correctly.
This commit fixes all remaining tests and adds a depdenceny to `transport-netty` from
`qa/smoke-test-http` and `modules/reindex` since they need an http server running on the nodes.
This also moves all required permissions for netty into it's module and out of core.
Today in the packaging removal scripts, we disable the service in
post-uninstall. Yet, this happens after service files have been
erased. On some systems, this can cause the service disable to fail
leaving behind state causing the service to be enabled on subsequent
installs. This commit moves the service disabling to the pre-uninstall
script to prevent this issue.

Today when a thread encounters a fatal unrecoverable error that
threatens the stability of the JVM, Elasticsearch marches on. This
includes out of memory errors, stack overflow errors and other errors
that leave the JVM in a questionable state. Instead, the Elasticsearch
JVM should die when these errors are encountered. This commit causes
this to be the case.

This commit updates the SHA for the JNA dependency. The JNA dependency
was upgraded from version 4.1.0 to version 4.2.2 in commit
7f10174362 but the SHA was not updated.
Unless explicitly disabled, the parallel new collector is enabled
automatically as soon as the CMS collector is enabled:
void Arguments::set_cms_and_parnew_gc_flags() {
assert(
!UseSerialGC && !UseParallelOldGC && !UseParallelGC,
"Error");
assert(UseConcMarkSweepGC, "CMS is expected to be on here");
// If we are using CMS, we prefer to UseParNewGC,
// unless explicitly forbidden.
if (FLAG_IS_DEFAULT(UseParNewGC)) {
FLAG_SET_ERGO(bool, UseParNewGC, true);
}
While it's fine to be explicit, the UseParNewGC flag is deprecatd in JDK
8 and produces warning messages in JDK 9:
Java HotSpot(TM) 64-Bit Server VM warning: Option UseParNewGC was
deprecated in version 9.0 and will likely be removed in a future
release.
Thus, we can and should just remove this flag from the default JVM
options.
