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.
Closes#20090
This commit sets the default min heap equal to the default max
heap. This is to align the default out-of-box settings with the heap
size bootstrap check.
This commit fixes the handling of spaces in the path to the jvm.options
file on Windows. The issue is that the extraneous set of quotes were
included as part of the value of ES_JVM_OPTIONS thus confusing further
downstream commands.

This commit updates Jackson to the 2.8.1 version, which is more strict when it comes to build objects. It also adds the snakeyaml dependency that was previously shaded in jackson libs.
It also closes#18076
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
for CLI tasks pertaining to Elasticsearch. Currently it implements only
a single sub-command, `truncate-translog`, that creates a truncated
translog for a given folder.
Here's what running the tool looks like:
```
λ bin/elasticsearch-translog truncate -d data/nodes/0/indices/P45vf_YQRhqjfwLMUvSqDw/0/translog/

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.
Closes#19079
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.

The setting bootstrap.mlockall is useful on both POSIX-like systems
(POSIX mlockall) and Windows (Win32 VirtualLock). But mlockall is really
a POSIX only thing so the name should not be tied POSIX. This commit
renames the setting to "bootstrap.memory_lock".

Recent changes adds an extra bin/ directory that contains Windows bat files in the normal Bin folder of elasticsearch. For exemple the script elasticsearch.bat is located in bin/bin/elasticsearch.bat instead of bin/elasticsearch.bat.
The distributions had their own copies of these extra files, which was a
carry over from maven. This change removes the duplicate files and
copies them from the root of the project.
closes#18597
This change tweaks the metadata version associated with the deb and rpm
packages. For rpm, dashes are allowed in versions, so we can use the
version as it already exists. For rpm, dashes are not allowed, so this
uses underscores instead. This only affects prerelease versions (eg
alpha/beta/rc), and usually someone doesn't specify the version, so the
inconsistency doesn't matter that much.
The default jvm.options file ships with the -server flag to force the
server VM on systems where the server VM is not the default. However,
the method of starting the JVM via the Windows service does not support
the command-line flags for selecting the VM because it starts from a
DLL that is specific to the server or client VM. Thus, we need to
filter these options from the jvm.options configuration file when
installing the Windows service.

Today when parsing settings during bootstrap, we add a system property
for every Elasticsearch setting. Additionally, settings can be set via
system properties. This commit simplifies this situation.
- settings are no longer propogated to system properties
- system properties can not be used to set settings
- the "es." prefix on settings is no longer required (nor permitted)
- test logging has a dedicated system property (tests.logger.level)

This change makes `gradle run` use the full zip distribution. Arguably
we could make it do the same when run inside plugins, but I started out
with this simple change. I am open to moving it into the RunTask itself
so that plugins will do this as well.
After considerable discussion, we have elected to set the default min
heap to 256m and the default max heap to 2g. This is to balance the
desire for a good out-of-the-box performance experience (default max
heap of 2g) with a good out-of-the-box experience running on machines
with limited resources or running multiple instances on a single modern
developer laptop (default min heap of 1g).
Benchmarking with the geonames data set shows that Elasticsearch truly
needs 2g of heap or the heap is a bottleneck for indexing rates. If our
goal is to satisfy the out-of-the-box-experience, we should prioritize
the out-of-the-box performance experience. Thus, the default heap should
be 2g until smaller heaps are not the bottleneck for indexing small data
sets.
This commit fixes the Debian package requires clause for bash. For the
RPM it is okay to specify the binary, but for the Debian package the
package name must be specified.
Today we encourage users to set their minimum and maximum heap settings
equal to each other to prevent the heap from resizing. Yet, the default
heap settings do not start Elasticsearch in this fashion. This commit
addresses this discrepancy by setting the default min heap to '512m' and
the default max heap to the default min heap.

This commit adds a hard requirement to the RPM and Debian packages for
/bin/bash to be present, and adds a note regarding this to the migration
docs.

In the plugin script we set the setting default.path.conf to control the
path to the configuration file. But the default directory might not
exist in which case we can run into exceptions. This commit restores a
guard against this directory not existing.
This commit switches the command-line scripts to use bash instead of sh
so that we can take advantage of features that bash provides like
arrays.

In 7d1fd17172 the parsing of command-line
properties in the plugin script was removed. That commit missed
additional parsing of the properties for es.default.path.conf. This
commit removes that parsing and also replaces the use of eval with exec.
Relates #18239
The plugin script parses command-line options looking for Java system
properties and extracts these arguments to pass to the java command when
starting the JVM. Since elasticsearch-plugin allows arbitrary user
arguments to the JVM via ES_JAVA_OPTS, this parsing is unnecessary. This
commit removes this unnecessary
