This commit configures the deprecation logs to be size-limited to 1 GB,
and compress these logs when they roll. The default configuration will
preserve up to four rolled logs.

Tests: Improve rest suite names and generated test names for docs tests
Add support for a RestClient base path
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.
Closes#20090
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.

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 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/

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.
Relates #19328
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".

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.

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.
Relates #18473
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)
Relates #18198
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.
Relates #18251
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
Relates #18207
Today we softly warn about running with the client VM. However, we
should really refuse to start in production mode if running with the
client VM as the performance of the client VM is too devastating for a
server application. This commit adds an option to jvm.options to ensure
that we are starting with the server VM (on all 32-bit non-Windows
platforms on server-class machines (2+ CPUs, 2+ GB physical RAM) this is
the default and on all 64-bit platforms this is the only option) and
adds a bootstrap check for the client VM.
Relates #18155
Today we specify the client option for the JVM when executing plugin
commands. Yet, this option does nothing on a 64-bit capable JDK as such
JDKs always select the Hotspot server VM. And for 32-bit JDKs, running
plugin commands with the server VM is okay. Thus, we should just remove
this unnecessary flag and just let the default VM be selected.
Relates #18142
This changes our packaging to be explicit about the permissions of files
and directories in the tar.gz, rpm, and deb packages. This is to protect
against a user having an incorrectly set umask when installing.
Additionally, plugins that are installed now have their permissions set
by the plugin installation so that plugins that may have been packaged
with incorrect permissions are secured.
Resolves#17634
In Elasticsearch 5.0.0, by default unquoted field names in JSON will be
rejected. This can cause issues, however, for documents that were
already indexed with unquoted field names. To alleviate this, a system
property has been added that can be enabled so migration can occur.
This system property will be removed in Elasticsearch 6.0.0
Resolves#17674
This commit simplifies the default JVM options that ship with
Elasticsearch. In particular, expert settings that were previously
configurable via environment variables have been removed from the
default configuration file. Further, the heap size settings have been
moved to the top of the file with a clearer message that is in
concordance with their importance.
Closes#17714
This commit sets the bad_env_var to a default value of 0 so that in case
no bad environment variables are encountered the variable is still
defined and does not later cause a parse error in the execution of these
batch files.
Relates #17675
JAVA_OPTS is not a built-in mechanism for passing options to the JVM but
many people think that it is. We do not respect JAVA_OPTS, but this
commit adds a warning if it is set in case the end-user thinks that it
will affect Elasticsearch.
This commit renames the function that parses JVM options in
bin/elasticsearch from jvm_options to parse_jvm_options. The reason for
the rename is because a for-loop variable was shadowing the name of this
function and changing the function name further clarifies the purpose of
the function.
This commit fixes the placement of a comment in bin/elasticsearch. The
comment was made out of place by the addition of a function definition
but order is restored.
This commit adds a new configuration file jvm.options to centralize and
simplify management of JVM options. This separates the configuration of
the JVM from the packaging scripts (bin/elasticsearch*, bin/service.bat,
and init.d/elasticsearch) simplifying end-user operational management of
custom JVM options.
This commit quotes the variable that contains the path to the java
binary. Without these quotes, when the arguments to eval are evaluated
the existing quotes will be removed leading to unquoted use of the path
to the java binary. If this path contains spaces, evaluation will fail.
