This commit modifies the BWC build to invoke the Gradle wrapper. The
motivation for this is two-fold:
- BWC versions might be dependent on a different version of Gradle than
the current version of Gradle
- in a follow-up we are going to need to be able to set JAVA_HOME to a
different value than the current value of JAVA_HOME

Java 9 added some enhancements to the internationalization support that
impact our date parsing support. To ensure flawless BWC and consistent
behavior going forward Java 9 runtimes requrie the system property
`java.locale.providers=COMPAT` to be set.

This commit adds the infrastructure to plugin building and loading to
allow one plugin to extend another. That is, one plugin may extend
another by the "parent" plugin allowing itself to be extended through
java SPI. When all plugins extending a plugin are finished loading, the
"parent" plugin has a callback (through the ExtensiblePlugin interface)
allowing it to reload SPI.
This commit also adds an example plugin which uses as-yet implemented
extensibility (adding to the painless whitelist).
* Adds task dependenciesInfo to BuildPlugin to generate a CSV file with dependencies information (name,version,url,license)
* Adds `ConcatFilesTask.groovy` to concatenates multiple files into one
* Adds task `:distribution:generateDependenciesReport` to concatenate `dependencies.csv` files into a single file (`es-dependencies.csv` by default)
# Examples:
$ gradle dependenciesInfo :distribution:generateDependenciesReport
## Use `csv` system property to customize the output file path
$ gradle dependenciesInfo :distribution:generateDependenciesReport -Dcsv=/tmp/elasticsearch-dependencies.csv
## When branch is not master, use `build.branch` system property to generate correct licenses URLs
$ gradle dependenciesInfo :distribution:generateDependenciesReport -Dbuild.branch=6.x -Dcsv=/tmp/elasticsearch-dependencies.csv
We document that users can set custom service names on Windows. Alas,

When running the release tests, we set build.snapshot to false and this
causes all version numbers to not have "-SNAPSHOT". This is true even
for the tips of the branches (e.g., currently 5.6.6 on the 5.6
branch). Yet, if we do not set snapshot to false, then we would still be
trying to find artifacts with "-SNAPSHOT" appended which would not have
been build since build.snapshot is false. To fix this, we have to push
build.snapshot into the version logic.

This commit reorganizes some of the content in the configuring
Elasticsearch section of the docs. The changes are:
- move JVM options out of system configuration into configuring
Elasticsearch
- move JVM options to its own page of the docs
- move configuring the heap to important Elasticsearch settings
- move configuring the heap to its own page of the docs
- move all important settings to individual pages in the docs
- remove bootstrap.memory_lock from important settings, this is covered

We have tests that manually unpackage the RPM and Debian package
distributions and start a cluster manually (not from the service) and
run a basic suite of integration tests against them. This is problematic
because it is not how the packages are intended to be used (instead,
they are intended to be installed using the package installation tools,
and started as services) and so violates assumptions that we make about
directory paths. This commit removes these integration tests, instead
relying on the packaging tests to ensure the packages are not
broken. Additionally, we add a sanity check that the package
distributions can be unpackaged. Finally, with this change we can remove
some leniency from elasticsearch-env about checking for the existence of
the environment file which the leniency was there solely for these
integration tests.

JDK 9 has removed JVM options that were valid in JDK 8 (e.g., GC logging
flags) and replaced them with new flags that are not available in JDK
8. This means that a single JVM options file can no longer apply to JDK
8 and JDK 9, complicating development, complicating our packaging story,
and complicating operations. This commit extends the JVM options syntax
to specify the range of versions the option applies to. If the running
JVM matches the range of versions, the flag will be used to start the
JVM otherwise the flag will be ignored.
We implement this parser in Java for simplicity, and with this we start
our first step towards a Java launcher.

This change ensures that the temporary directory used for java.io.tmpdir

jvm.options, we set ES_TMPDIR respectively in our startup scripts, and
resolve the value of the template ${ES_TMPDIR} at startup.

Any CLI commands that depend on core Elasticsearch might touch classes
(directly or indirectly) that depends on logging. If they do this and
logging is not configured, Log4j will dump status error messages to the
console. As such, we need to ensure that any such CLI command configures
logging (with a trivial configuration that dumps log messages to the
console). Previously we did this in the base CLI command but with the
refactoring of this class out of core Elasticsearch, we no longer
configure logging there (since we did not want this class to depend on
settings and logging). However, this meant for some CLI commands (like
the plugin CLI) we were no longer configuring logging. This commit adds
base classes between the low-level command and multi-command classes
that ensure that logging is configured. Any CLI command that depends on
core Elasticsearch should use this infrastructure to ensure logging is
configured. There is one exception to this: Elasticsearch itself because
it takes reponsibility into its own hands for configuring logging from
Elasticsearch settings and log4j2.properties. We preserve this special
status.

This commit removes the ability to use ${prompt.secret} and

Projects the depend on the CLI currently depend on core. This should not
always be the case. The EnvironmentAwareCommand will remain in :core,

Only tests should use the single argument Environment constructor. To

This commit adjusts the format of the SHA-512 checksum files supported

This commit fixes an issue with the handling of paths containing

protecting this echo statement by wrapping the possibly offending path
in quotes.

* Removes minimum master nodes default number
At the moment the elasticsearch.yml contains the minimum master node setting commented out but with a value of 3. This has lead to users uncommenting the value and assuming it is a good default without reading that they need to change it to a quorum of master eligible nodes causing split brain in their cluster and defeating the point of the setting.
The default of 3 is not even a good default for our recommended setup of 3 dedicated master eligible nodes.
This changes the value o fthe commented out setting to something that will not produce valid config and should highlight that the value needs to be changed so users no longer uncomment the line without considering what the correct value for their setup should be.
* Addresses review comment
The JVM defaults to dumping the heap to the working directory of
Elasticsearch. For the RPM and Debian packages, this location is
/usr/share/elasticsearch. This directory is not writable by the
elasticsearch user, so by default heap dumps in this situation are
lost. This commit modifies the packaging for the RPM and Debian packages
to set the heap dump path to /var/lib/elasticsearch as the default
location for dumping the heap. This location is writable by the
elasticsearch user by default. We add documentation of this important
setting if /var/lib/elasticsearch is not suitable for receiving heap
dumps.

The output when building bwc versions is currently verbose, with git
warnings from doing git checkout of a hash. This commit changes this to

still be dumped.
When creating the keystore explicitly (from executing
elasticsearch-keystore create) or implicitly (for plugins that require
the keystore to be created on install) on an Elasticsearch package
installation, we are running as the root user. This leaves
/etc/elasticsearch/elasticsearch.keystore having the wrong ownership
(root:root) so that the elasticsearch user can not read the keystore on
startup. This commit adds setgid to /etc/elasticsearch on package
installation so that when executing this directory (as we would when
creating the keystore), we will end up with the correct ownership
(root:elasticsearch). Additionally, we set the permissions on the
keystore to be 660 so that the elasticsearch user via its group can read
this file on startup.

This commit adds files to the build output called build_metadata which

At current, we do not feel there is enough of a reason to shade the low

gather more information is best. Users can still shade the jar

This commit makes the security code aware of the Java 9 FilePermission changes (see #21534) and allows us to remove the `jdk.io.permissionsUseCanonicalPath` system property.
When Elasticsearch starts up, it tries to create a keystore if one does
not exist; this is so the keystore can be seeded. With the RPM and
Debian packages, the keystore would be located in
/etc/elasticsearch. This configuration directory is typically not
writable by the elasticsearch user so the Elasticsearch process will not
have permission to create the keystore. Instead, the RPM and Debian
packages should create the keystore (if it does not exist) on package
installation. This commit enables these packages to do that in the
post-install routines.

We need to check if JAVA_TOOL_OPTIONS, and JAVA_OPTS are set, and if

not. This commit does that.

We previously explicitly set the HOSTNAME environment variable so that
${HOSTNAME} could be used a placeholder for defining the node.name in
elasticsearch.yml. We removed explicitly setting this because bash
defines HOSTNAME. The problem is that bash defines HOSTNAME as a bash
variable, not as an environment variable. Therefore, to restore the
previous behavior, we export the bash value for HOSTNAME as an
environment variable named HOSTNAME. For consistency between Windows and
the Unix-like systems, we also define HOSTNAME with a value equal to the
environment variable COMPUTERNAME on Windows.
Relates #26262
We quoted some strings in the Windows elasticsearch-env script but echo
on Windows includes these quotes in the output. This commit removes
these quotes, they do not need to be output and are noise. Note that one
of the commands is wrapped in parentheses, this is to make obvious that
the space at the end of the corresponding line is intentionally there.
The error message for warning about the use of JAVA_TOOL_OPTIONS on
Windows incorrectly uses $JAVA_TOOL_OPTIONS to dereference the
environment variable JAVA_TOOL_OPTIONS; on Windows it should be
%JAVA_TOOL_OPTIONS%.
This instruction tells systemd to create a directory /var/run/elasticsearch before starting Elasticsearch.
Without this change, the default PID_DIR (/var/run/elasticsearch) may not exist, and without it, Elasticsearch will fail to start.
The environment variable CONF_DIR was previously inconsistently used in
our packaging to customize the location of Elasticsearch configuration
files. The importance of this environment variable has increased
starting in 6.0.0 as it's now used consistently to ensure Elasticsearch
and all secondary scripts (e.g., elasticsearch-keystore) all use the
same configuration. The name CONF_DIR is there for legacy reasons yet
it's too generic. This commit renames CONF_DIR to ES_PATH_CONF.

In bin/elasticsearch, we grep the command line looking for various flags

the command status. This commit fixes this issue.

The build was ignoring suffixes like "beta1" and "rc1" on the version numbers which was causing the backwards compatibility packaging tests to fail because they expected to be upgrading from 6.0.0 even though they were actually upgrading from 6.0.0-beta1. This adds the suffixes to the information that the build scrapes from Version.java. It then uses those suffixes when it resolves artifacts build from the bwc branch and for testing.

Raw requests are supported only by the java yaml test runner and were introduced to test docs snippets. Some yaml tests ended up using them (see #23497) which causes failures for other language clients. This commit migrates those yaml tests to Java tests that send requests through the Java low-level REST client, and also moves the ability to send raw requests to a special client that's only available when testing docs snippets.
Closes#25694
Today our shell scripts march on if they encounter an error during
execution. One place that this actually causes a problem is with the
Java version checker. What can happen is this: if the user botches their
installation so that the JavaVersionChecker can not be found on the
classpath, when we attempt to run the Java version checker, first an
error message that the class can not be found is displayed, and then we
print a message that their version of Java is not compatible; this
happens even if they are using a Java 8 installation. The problem is
that we should have immediately aborted when the class could not be
loaded. Since we do not exit when the shell script encounters an error,
we end up conflating failue to run the version check with a failed
version check. Instead, we really should abort the moment that one of
our scripts encounters an error. To do this, we make the following
changes:
- enable set -e and set -o pipefail
- make the Java version checker responsible for printing the error
message to the console
- remove the exit status check from the scripts
- actually on Windows, we still have to check the exit status because
there is no equivalent of set -e
- when we check for daemonization, we can no longer check the exit
status from grep because a failed grep will abort the script;
instead, we move the grep execution to be the condition for the if as
this does not trip the set -e failure conditions
- we should source elasticsearch-env before doing anything, so we move
the definition of parse_jvm_options below sourcing elasticsearch-env
- we make consistent all places where we use a subshell to use
backticks

We have a bootstrap check for the maximum size of the virtual memory
address space for the Elasticsearch process. We can set this in the
service file for Elasticsearch when installed as a service on
systemd-based systems for a better user experience than them fumbling
through thinking they should set this via /etc/security/limits.d (as a
lot of pages on the Internet would tell them) not realizing that systemd
completely ignores these for services and then trying to figure out how
to add a unit file for the Elasticsearch service.

The systemd service file that ships with Elasticsearch installs on
systemd-based systems contains a suggestion for setting LimitMEMLOCK if
the user wants to enable bootstrap.memory_lock. However, this setting

how to set this. Therefore, we should not have this suggestion in the
service file otherwise users might be led to think they should edit it
there.

On non-Windows platforms, we ignore the environment variable
JAVA_TOOL_OPTIONS (this is an environment variable that the JVM respects
by default for picking up extra JVM options). The primary reason that we
ignore this because of the Jayatana agent on Ubuntu; a secondary reason
is that it produces an annoying "Picked up JAVA_TOOL_OPTIONS: ..."
output message. When the elasticsearch-env batch script was introduced
for Windows, ignoring this environment variable was deliberately not
carried over as the primary reason does not apply on Windows. However,
after additional thinking, it seems that we should simply be consistent
to the extent possible here (and also avoid that annoying "Picked up
JAVA_TOOL_OPTIONS: ..." on Windows too). This commit causes the Windows
version of elasticsearch-env to also ignore JAVA_TOOL_OPTIONS.

When invoking the elasticsearch-env.bat batch script on Windows, if the
script exits due to an error (e.g., Java can not be found, or the wrong

this does not also terminate the caller, instead returning control. This
means we have to explicitly exit so that is what we do in this commit.

Today we strip some ignored JVM options before starting the main Java
process (e.g., we unset JAVA_TOOL_OPTIONS, and we ignore
JAVA_OPTS). However, there is another Java process that we start before
starting the main process: the Java version checker. We are currently
starting this before ignoring the undesired JVM options so the Java
version checker will pick up JAVA_TOOL_OPTIONS and it will silently
ignore JAVA_OPTS. Instead, we should ignore JAVA_TOOL_OPTIONS here too,
and not silently ignore JAVA_OPTS but instead warn before doing so (as
we already do for the main Java process). This commit rearranges the
execution of these steps so that we do the right thing here.

This commit removes a legacy check against running bin/elasticsearch
that is not produced from a distribution. This check exists for legacy
reasons, namely when bin/elasticsearch previously sat in the root of the
Elasticsearch repository. In this old scenario, someone might clone the
repository, see the bin folder and try to run bin/elasticsearch without
first production a distribution. Today, this is unlikely since
bin/elasticsearch now sits in
distribution/src/main/resources/bin/elasticsearch so first, bin is no
longer in the root of the repository, and second, the src indicates this
is source and not already for production. Moreover, our README in the
root of the repository provides clear instructions for getting started:
either download a distribution or build one from source. In the name of
simplicity, we therefore remove this legacy check.
Relates #25960
This commit cleans up a few items with the script packaging:
- remove the now dead elasticsearch.in.sh script
- add assertions for the existence elasticsearch-env and
elasticsearch-keystore
This commit addresses a change in core Elasticsearch where the
command-line flag --path.conf is no longer respected. Instead, the
configuration path must be passed through the system property
es.path.conf. We adapt the Windows batch file and the service for this
change.
This commit fixes tests for environment-aware commands. A previous
change added a check that es.path.conf is not null. The problem is that
this system property is not being set in tests so this check trips every
single time. To fix this, we move the check into a method that can be
overridden, and then override this method in relevant places in tests to
avoid having to set the property in tests. We also add a test that this
check works as expected.
A previous change enabled it so that users could configure the
configuration path via a command-line option --path.conf. However, a
subsequent change has made it so that we expect users to set the
configuration path via the environment variable CONF_DIR. To enable
this, we now pass the value of CONF_DIR as the value for the
command-line option --path.conf. This has two problems:
- the presence of --path.conf always being on the command line breaks
other flags like --help for multi-commands
- the scripts for which --help is not broken say that you can pass
--path.conf but this is a lie since passing it will make it appear
twice in the command-line arguments breaking the script
Since --path.conf is no longer the way that we want users to set the
configuration path, we should remove the --path.conf option. However, we
still need a way to get the configuration path from the scripts to the
running Java process. To do this, we now pass the configuration path as
a system property. This keeps it off the script command line fixing the
above problems.
The only remaining question (that I can see) is whether or not to
respect -Des.path.conf=<some path> if the user sets this in their
jvm.options or via ES_JAVA_OPTS. I think that we should not do this (as
has been our tradition), es.path.home and es.path.conf are special,
should be set by our scripts only so users should not be setting them at
all so we should not take any effort to respect these flags if the user
tries to otherwise use them.
Relates #25943
When running a script that depends on elasticsearch-env, the
elasticsearch-env script seeks backwards from the directory containing
the script to find Elasticsearch home. This is done by seeking backwards
in the path to find bin, and then going one directory above
that. Unfortunately, if the script is started relatively from the bin
directory, then bin will appear in the path since it is a relative
path. This commit fixes this by making the starting path absolute before
attempting to seek backwards.
This commit removes all external dependencies from the rest client jar

The quoting for the ExecStart entry is broken as quotes must wrap an
entire argument, and arguments are separated by spaces. It turns out
that any quoting is unnecessary here, systemd will handle it correctly
either way.
This commit introduces the elasticsearch-env script. The purpose of this
script is threefold:
- vastly simplify the various scripts used in Elasticsearch
- provide a script that can be included in other scripts in the
Elasticsearch ecosystem (e.g., plugins)
- correctly establish the environment for all scripts (e.g., so that
users can run `elasticsearch-keystore` from a package distribution
without having to worry about setting `CONF_DIR` first, otherwise the
keystore would be created in the wrong location)

Today we explicitly export the HOSTNAME variable from scripts. This is
probably a relic from the days when the scripts were not run on bash but

not need to set it in scripts. This commit removes this legacy.

Today we enable users to customize the environment through the use of
ES_INCLUDE. This made sense for legacy reasons when we did not have

for ES_INCLUDE as a first step towards a dedicated include script.

The problem here is simple: when using direct buffers as in NIO, the JDK
relies on explict GC invocataions to trigger cleaning up direct buffers;
if such GCs do not occur and the direct buffer limit is reached, the JVM
will throw an out of memory exception. With explicit GCs disabled, the
JVM is neutered from explicitly cleaning up direct buffers in the act of
reserving a new direct buffer and instead relies on a GC occurring for
another reason. If such a GC never occurs, the JVM will OOM. This commit
removes disabling of explicit GCs. Note that these explicit GCs only
occur as a last ditch effort before going OOM when the JVM is trying to
reserve more direct memory. This is a known issue, see for example:
JDK-8142537.

This commit changes the default heap size to 1 GB. Experimenting with

should) adjust the heap size as necessary for their usecase.

On Debian-based systems the install scripts are run with set -e meaning
that if there is an error in executing one of these scripts then the

fail leading to the post-install script failing. Instead, we should
account for the possbility of failure here by not letting the command to
restart this service exit with non-zero status code. This commit does
this, and adds a test for this situation.

This is a regression introduced in #25510, which removed the explicit fetching of upstream. Sadly this doesn't work if you don't have any local branch referring to `upstream` as an upstream branch.
Some times we need a fix / change to have two parts in two different branches (corresponding to two different ES releases). In order to be able to test these cases you need to run the BWC tests against a local branch rather than then using a branch from `github.com/elastic/elasticsearch`.
This commit adds a system property called `tests.bwc.refspec` that allows you to do it. Note that I've chosen to go with the simplest code change for now, at the expense of some user friendliness.
We previously tried to maintain (while not formally supporting) 32-bit

Removes the `assemble` task from the `build` task when we have
removed `assemble` from the project. We removed `assemble` from
projects that aren't published so our releases will be faster. But
That broke CI because CI builds with `gradle precommit build` and,
it turns out, that `build` includes `check` and `assemble`. With
this change CI will only run `check` for projects without an
`assemble`.
Removes the `assemble` task from projects that are not published.
This should speed up `gradle assemble` by skipping projects that
don't need to be built. Which is useful because `gradle assemble`
is how we cut releases.
This prevents possible race conditions between the Elasticsearch JVM and
plugin native controller processes that can cause the Elasticsearch shutdown
to hang. The problem can happen when the JVM and the controller process
receive a SIGTERM at almost the same time.
(There's an assumption here that Elasticsearch will continue to use other
mechanisms to kill native controller processes.)
This commit changes the task type of the checkoutBwcBranch task to Exec

Commit bf007e8d93 was a forward port of logic needed in 5.x to get
the correct bwc branch. However, other changes on master meant that this forward port was not
needed and actually broke the bwc tests. This change removes the incorrect if statement.
Relates #25134
When testing against the previous 5.x release, the bwc project incorrectly would checkout the 5.x
branch instead of the 5.5 branch as it still had the logic that applies for major versions bwc. This change adds
a check to compare the major version when making the decision on the branch to use.
During package install on systemd-based systems, some sysctl settings
should be set (e.g. vm.max_map_count).
In some environments, changing sysctl settings plainly does not work;
previously a global environment variable named
ES_SKIP_SET_KERNEL_PARAMETERS was introduced to skip calling sysctl, but
this causes trouble for:
- configuration management systems, which usually cannot apply an env
var when running a package manager
- package upgrades, which will not have the env var set any more, and
thus leaving the package management system in a bad state (possibly
half-way upgraded, can be very hard to recover)
This removes the env var again and instead of calling systemd-sysctl
manually, tells systemd to restart the wrapper unit - which itself can
be masked by system administrators or management tools if it is known
that sysctl does not work in a given environment.
The restart is not silent on systems in their default configuration, but
is ignored if the unit is masked.

* Adds nodes usage API to monitor usages of actions
The nodes usage API has 2 main endpoints
/_nodes/usage and /_nodes/{nodeIds}/usage return the usage statistics
for all nodes and the specified node(s) respectively.
At the moment only one type of usage statistics is available, the REST
actions usage. This records the number of times each REST action class is
called and when the nodes usage api is called will return a map of rest
action class name to long representing the number of times each of the action
classes has been called.
Still to do:
* [x] Create usage service to store usage statistics
* [x] Record usage in REST layer
* [x] Add Transport Actions
* [x] Add REST Actions
* [x] Tests
* [x] Documentation
* Rafactors UsageService so counts are done by the handlers
* Fixing up docs tests
* Adds a name to all rest actions
* Addresses review comments
By default, the remove plugin CLI command preserves configuration
files. This is so that if a user is upgrading the plugin (which is done
by first removing the old version and then installing the new version)
they do not lose their configuration file. Yet, there are circumstances
where preserving the configuration file is not desired. This commit adds
a purge option to the remove plugin CLI command.

Removes the `distribution:bwc` project in favor of
`distribution:bwc-release-snapshot` and
`distribution:bwc-stable-snapshot`.
`distribution:bwc-release-snapshot` builds a snapshot of the
latest release branch (5.4 now) if needed for backwards
compatibility. `distribution:bwc-stable-snapshot` builds a
snapshot of the latest stable branch (5.x now) if needed for
backwards compatibility.
Some packaging tests depend on snapshot versions of packaging
distributions yet the build does not use a repository that includes such
distributions. While we could add such a repository, a better strategy
is to follow our approach for other BWC tests where we depend on a
locally-compiled archive distribution. This commit adds a local
compilation of packaging artifacts and substitutes these anywhere that
we would otherwise depend on a snapshot of these artifacts.

This commit expands the logic for version extraction from Version.java
to include a list of all versions for backcompat purposes. The tests
using bwcVersion are converted to use this list, but those tests
(rolling upgrade and backwards-5.0) are still not randomized; that will
happen in another followup.
This commit renames all rest test files to use the .yml extension
instead of .yaml. This way the extension used within all of
elasticsearch for yaml is consistent.
We had a hack in setting up permissions for tests to support testing
the lang-python plugin. We also had a hack to prevent Log4j from

When installing plugin permissions, we try to set the permissions on all
installed files ourselves because a umask from the user could violate
everything needed to get the permissions right. Sadly, directories were
not handled correctly at all and so we were still left with broken
installations with umasks like 0077. This commit fixes this issue, adds
a thorough unit test for the situation, and most importantly, adds a
test that sets the umask before installing the plugin.

This adds `-XX:-OmitStackTraceInFastThrow` to the JVM arguments
which *should* prevent the JVM from omitting stack traces on

This also adds the flag when running tests and adapts some tests
that had workarounds for the absense of the flag.
Closes#24376
This commit fixes an issue when deleting the plugin directory while
executing the remove plugin command. Namely, we take out a file
descriptor on the plugin directory to traverse its contents to obtain
the list of files to delete. We leaked this file descriptor. On
Unix-based filesystems, this is not a problem, deleting the plugin
directory deletes the plugin directory. On Windows though, a delete is
not executed until the last file descriptor is closed. Since we leaked
this file descriptor, the plugin was not actually deleted. This led to
test failures that tried to cleanup left behind temporary directories
but these test failures were just exposing this bug. This commit fixes
this issue by ensuring that we close the file descriptor to the plugin
directory when we are finished with it.
Relates #24266
Today when removing a plugin, we attempt to move the plugin directory to
a temporary directory and then delete that directory from the
filesystem. We do this to avoid a plugin being in a half-removed
state. We previously tried an atomic move, and fell back to a non-atomic
move if that failed. Atomic moves can fail on union filesystems when the
plugin directory is not in the top layer of the
filesystem. Interestingly, the regular move can fail as well. This is
because when the JDK is executing such a move, it first tries to rename
the source directory to the target directory and if this fails with
EXDEV (as in the case of an atomic move failing), it falls back to
copying the source to the target, and then attempts to rmdir the
source. The bug here is that the JDK never deleted the contents of the
source so the rmdir will always fail (except in the case of an empty
directory).
Given all this silliness, we were inspired to find a different
strategy. The strategy is simple. We will add a marker file to the
plugin directory that indicates the plugin is in a state of
removal. This file will be the last file out the door during removal. If
this file exists during startup, we fail startup.
Relates #24252
The plugin cli currently resides inside the elasticsearch jar. This
commit moves it into a plugin-cli jar. This is change alone is a no-op;
it does not change anything about what is loaded at runtime. But it will
allow easier testing (with fixtures in the future to test ES or maven
installation), as well as eventually not loading these classes when
starting elasticsearch.
This change simplifies how the rest test runner finds test files and
removes all leniency. Previously multiple prefixes and suffixes would
be tried, and tests could exist inside or outside of the classpath,
although outside of the classpath never quite worked. Now only classpath
tests are supported, and only one resource prefix is supported,
`/rest-api-spec/tests`.
closes#20240
After splitting integ tests into cluster configuration and the test
runner task, we still have dependencies of the test runner added as deps
of the cluster. This commit adds dependencies directly to the cluster,
so that the runner can have other dependencies independent of what is
needed for the cluster.
The bwc checkout for backcompat tests currently always tries to fetch
the latest from the upstream remote. This change makes fetching from
upstream conditional on not running an offline build.
Adds the option for a plugin to specify extra directories containing notices
and licenses files to be incorporated into the overall notices file that is
generated for the plugin.
This can be useful, for example, where the plugin has a non-Java dependency
that itself incorporates many 3rd party components.
Windows rest tests consistenly fail because the filesystem appears to be
an order of magnitude slower than that of *nix, at least in the context
of our rest tests. This commit overrides the suite timeout to 30 mins
for windows. From past failures, it appears this should be enough, as
the tests seem to fail when they are almost complete. The default suite
timeout for ESTestCase is 20 mins, so this leaves ample buffer for
windows shenanigans.
The LoggedExec task does not capture output when info logging is
enabled. This commit changes the upstream check to use Exec directly,
so as not to break when info logging is enabled.
This will use File.toString() for the `git clone` command, which will

We currently have the last minor version of the previous major hardcoded
in tests like rolling upgrade. This change programatically finds this
during gradle initialization by parsing versions from Version.java.
This commit switches from executing gradle when building the bwc testing
zip through Exec, to using GradleBuild. In addition to not depending on
gradle being in the PATH, it also has the added benefit of much better
logging while the bwc build is going on (the actual tasks show up as
tasks of a subproject within the current build).
The current rest backcompat tests, which run against a mixed cluster of
5.x and 6.0 nodes, depend on snapshot builds of 5.x. However, this has
the potential for inconsistency that results in CI failures, and happens
quite often, whenever some backcompat logic is added to 5.x, but the bwc
test on master fails because the 5.x code has not yet been published as
a snapshot.
This change creates a git clone of the 5.x branch,
builds the zip distribution, and ties that into gradle substitutions for
the 5.x version.
After the removal of the joda time hack we used to have, we can cleanup
the codebase handling in security, jarhell and plugins to be more picky

Gradle's finalizedBy on tasks only ensures one task runs after another,
but not immediately after. This is problematic for our integration tests
since it allows multiple project's integ test clusters to be
simultaneously. While this has not been a problem thus far (gradle 2.13
happened to keep the finalizedBy tasks close enough that no clusters
were running in parallel), with gradle 3.3 the task graph generation has
changed, and numerous clusters may be running simultaneously, causing
memory pressure, and thus generally slower tests, or even failure if the
system has a limited amount of memory (eg in a vagrant host).
This commit reworks how integ tests are configured. It adds an
`integTestCluster` extension to gradle which is equivalent to the current
`integTest.cluster` and moves the rest test runner task to
`integTestRunner`. The `integTest` task is then just a dummy task,
which depends on the cluster runner task, as well as the cluster stop
task. This means running `integTest` in one project will both run the
rest tests, and shut down the cluster, before running `integTest` in
another project.
This commit enforces the requirement of Content-Type for the REST layer and removes the deprecated methods in transport
requests and their usages.
While doing this, it turns out that there are many places where *Entity classes are used from the apache http client
libraries and many of these usages did not specify the content type. The methods that do not specify a content type
explicitly have been added to forbidden apis to prevent more of these from entering our code base.

Today when users start Elasticsearch with their Java configuration
pointing to a pre-Java 8 install, they encounter a cryptic message:
Exception in thread "main" java.lang.UnsupportedClassVersionError:
org/elasticsearch/bootstrap/Elasticsearch : Unsupported major.minor
version 52.0
They often think that they have Java 8 installed but if their JAVA_HOME
or other configuration is causing them to start with a pre-Java 8
install, this error message does not help them.
We introduce a Java version checker that runs on Java 6 as part of the
startup scripts. If the Java version is pre-Java 8, we can display a
helpful error message to the user informing them of the Java version
that the runtime was started with. Otherwise, Elasticsearch starts as it
does today.
This change adds a strict mode for xcontent parsing on the rest layer. The strict mode will be off by default for 5.x and in a separate commit will be enabled by default for 6.0. The strict mode, which can be enabled by setting `http.content_type.required: true` in 5.x, will require that all incoming rest requests have a valid and supported content type header before the request is dispatched. In the non-strict mode, the Content-Type header will be inspected and if it is not present or not valid, we will continue with auto detection of content like we have done previously.
The content type header is parsed to the matching XContentType value with the only exception being for plain text requests. This value is then passed on with the content bytes so that we can reduce the number of places where we need to auto-detect the content type.
As part of this, many transport requests and builders were updated to provide methods that
accepted the XContentType along with the bytes and the methods that would rely on auto-detection have been deprecated.
In the non-strict mode, deprecation warnings are issued whenever a request with body doesn't provide the Content-Type header.
See #19388
By default, the JVM GC log file grows without
limitation. This is inconvenient for a long running
process like Elasticsearch.
With this commit we add an example configuration
for a rotating GC log in `conig/jvm.options`.
For certain situations, end-users need the base path for Elasticsearch
logs. Exposing this as a property is better than hard-coding the path
into the logging configuration file as otherwise the logging
configuration file could easily diverge from the Elasticsearch
configuration file. Additionally, Elasticsearch will only have
permissions to write to the log directory configured in the
Elasticsearch configuration file. This commit adds a property that
exposes this base path.
One use-case for this is configuring a rollover strategy to retain logs
for a certain period of time. As such, we add an example of this to the
documentation.
Additionally, we expose the property es.logs.cluster_name as this is
used as the name of the log files in the default configuration.
Finally, we expose es.logs.node_name in cases where node.name is
explicitly set in case users want to include the node name as part of
the name of the log files.

Right now closing a shard looks like it strands refresh listeners,
causing tests like
`delete/50_refresh/refresh=wait_for waits until changes are visible in search`
to fail. Here is a build that fails:
https://elasticsearch-ci.elastic.co/job/elastic+elasticsearch+multi_cluster_search+multijob-darwin-compatibility/4/console
This attempts to fix the problem by implements `Closeable` on
`RefreshListeners` and rejecting listeners when closed. More importantly
the act of closing the instance flushes all pending listeners
so we shouldn't have any stranded listeners on close.
Because it was needed for testing, this also adds the number of
pending listeners to the `CommonStats` object and all API to which
that flows: `_cat/nodes`, `_cat/indices`, `_cat/shards`, and
`_nodes/stats`.
Netty plays a lot of games with recycling byte buffers in thread local
caches, and using a pooled byte buffer allocator to reduce pressure on
the garbage collector.
The recycler in particular appears to be fraught with peril. It appears
that there are circumstances where the recycler does not recycle quickly
enough and can exceed its capacity leading to heap exhaustion and out of
memory errors. If you spend a few minutes reading the history of the
recycler on the Netty GitHub issues, it appears it has been nothing but
a source of trouble, and the project itself has an open issue that
proposes disabling by default and possibly even removing the recycler.
The pooled byte buffer allocator has problems itself. It sizes the pool
based on the number of runtime processors and can indeed grab a very
large percentage of the heap (in some cases 50% or more). Additionally,
the Netty project continues to struggle with leaks here.
We are seeing users struggle with issues in 5.x that I think are largely
driven by some of the problems here with Netty.
This change proposes to disable the recycler, and to disable the pooled
byte buffer allocator. I think that disabling these features will return
some of the stablity that these features appear to be losing us.
I have done performance testing on my workstation with disabling these
and I do not see a difference in performance. I propose that we make
this change in master and let some nightly benchmarks run to confirm
that there is not a difference in performance. If we are comfortable
with the performance changes, I propose backporting this to all active
branches.

This change is the first towards providing the ability to store
sensitive settings in elasticsearch. It adds the
`elasticsearch-keystore` tool, which allows managing a java keystore.
The keystore is loaded upon node startup in Elasticsearch, and used by
the Setting infrastructure when a setting is configured as secure.
There are a lot of caveats to this PR. The most important is it only
provides the tool and setting infrastructure for secure strings. It does
not yet provide for keystore passwords, keypairs, certificates, or even
convert any existing string settings to secure string settings. Those
will all come in follow up PRs. But this PR was already too big, so this
at least gets a basic version of the infrastructure in.
The two main things to look at. The first is the `SecureSetting` class,
which extends `Setting`, but removes the assumption for the raw value of the
setting to be a string. SecureSetting provides, for now, a single
helper, `stringSetting()` to create a SecureSetting which will return a
SecureString (which is like String, but is closeable, so that the
underlying character array can be cleared). The second is the
`KeyStoreWrapper` class, which wraps the java `KeyStore` to provide a
simpler api (we do not need the entire keystore api) and also extend
the serialized format to add metadata needed for loading the keystore
with no assumptions about keystore type (so that we can change this in
the future) as well as whether the keystore has a password (so that we
can know whether prompting is necessary when we add support for keystore
passwords).
* Remove a checked exception, replacing it with `ParsingException`.
* Remove all Parser classes for the yaml sections, replacing them with static methods.
* Remove `ClientYamlTestFragmentParser`. Isn't used any more.
* Remove `ClientYamlTestSuiteParseContext`, replacing it with some static utility methods.
I did not rewrite the parsers using `ObjectParser` because I don't think it is worth it right now.
A previous fix for the handling of paths on Windows related to paths
containing multiple spaces introduced a issue where if JAVA_HOME ends

not regressing the previous fix.

Elasticsearch can be run in a few different ways:
- from the command line on Linux and Windows
- as a service on Linux and Windows
on both 32-bit client and 64-bit server VMs. We strive for a great
out-of-the-box experience any of these combinations but today it is
lacking on 32-bit client JVMs and on the Windows service. There are two
deficiencies that arise:
- on any 32-bit client JVM we fail to start out of the box because we
force the server JVM in jvm.options
- when installing the Windows service, the thread stack size must be
specified in jvm.options
This commit attempts to address these deficiencies.
We should continue to force the server JVM because there are systems
where the server JVM is not active by default (e.g., the 32-bit JDK on
Windows). This does mean that if a user tries to run with a client JVM
they will see a failure message at startup but this is the best that we
can do if we want to continue to force the server JVM. Thus, this commit
at least documents this situation.
To improve the situation with installing the Windows service, this
commit adds a default setting for the thread stack size. This default is
chosen based on the default thread stack size across all 64-bit server
JVMs. This means that if a user tries to run with a 32-bit JVM they
could otherwise see significantly higher memory usage (this situation is
complicated, it's really only on Windows where the extra memory usage is
egregious, but cutting into the 32-bit address space on any system is
bad). So this commit makes it so that the out-of-the-box experience is
improved for the Windows service on 64-bit server JVMs and we document
the need to adjust this setting on 32-bit JVMs.
Again, we are focusing on the out-of-the-box experience here and this
means optimizing for the best experience on any 64-bit server JVM as
this covers the vast majority of the user base. The users that are on
32-bit JVMs will suffer a little bit but at least now any user on any
64-bit server JVM can start Elasticsearch out of the box.
Finally, we fix some references to the jvm.options documentation.

On some systems these utilities are in /usr/lib/systemd/systemd-sysctl

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.

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.

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

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.

This change removes the old maven deploy that we have in parallel to

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.

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

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.

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.

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

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

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

out a setting by just removing the #, the setting actually

With the security permissions that we grant to Netty, Netty can not
access unsafe (because it relies on having the runtime permission

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 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

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.

Unless explicitly disabled, the parallel new collector is enabled

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

Thus, we can and should just remove this flag from the default JVM
options.

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

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.

The plugin script parses command-line options looking for Java system

In preparation for a unified release process, we need to be able to
generate the pom files independently of trying to actually publish. This
change adds back the maven-publish plugin just for that purpose. The
nexus plugin still exists for now, so that we do not break snapshots,
but that can be removed at a later time once snapshots are happenign
through the unified tools. Note I also changed the dir jars are written
into so that all our artifacts are under build/distributions.
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.

Today when restarting Elasticsearch using the start-stop-daemon on

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

the function.
This commit fixes the placement of a comment in bin/elasticsearch. The

This commit adds a new configuration file jvm.options to centralize and

custom JVM options.

Change version, required a minor fix in the RPM building.
In case of a alpha/beta version, the release will contain alpha/beta
as the RPM version cannot contains dashes/tildes.
The build currently uses the old maven support in gradle. This commit
switches to use the newer maven-publish plugin. This will allow future
changes, for example, easily publishing to artifactory.
An additional part of this change makes publishing of build-tools part
of the normal publishing, instead of requiring a separate upload step
from within buildSrc. That also sets us up for a follow up to enable
precomit checks on the buildSrc code itself.
This commit fixes the pidfile setting on systems that used systemd. The
issue is that the pidfile can only be set via the command line arguments
-p or --pidfile, and is no longer settable via a setting.
Today, certain bootstrap properties are set and read via system
properties. This action-at-distance way of managing these properties is
rather confusing, and completely unnecessary. But another problem exists
with setting these as system properties. Namely, these system properties
are interpreted as Elasticsearch settings, not all of which are
registered. This leads to Elasticsearch failing to startup if any of
these special properties are set. Instead, these properties should be
kept as local as possible, and passed around as method parameters where
needed. This eliminates the action-at-distance way of handling these
properties, and eliminates the need to register these non-setting
properties. This commit does exactly that.
Additionally, today we use the "-D" command line flag to set the
properties, but this is confusing because "-D" is a special flag to the
JVM for setting system properties. This creates confusion because some
"-D" properties should be passed via arguments to the JVM (so via
ES_JAVA_OPTS), and some should be passed as arguments to
Elasticsearch. This commit changes the "-D" flag for Elasticsearch
settings to "-E".
Enables the touching of all memory pages used by the JVM heap spaces
during initialization of the HotSpot VM, which commits all memory pages
at initialization time. By default, pages are committed only as they are
needed.

update to lucene 6 jars
Removes all our logger wrappers except the wrapper for log4j1.2. If you
depend on Elasticsearch's jar in your application you'll need to declare
log4j 1.2 and/or some bridge to your favorite logger.
We did this to simplify our builds and code. No more commons-logging like
log implementation sniffing. No more optional dependency hacks in gradle.
We might one day want to use j.u.l instead of log4j. If we do want that
we can recover its wrapper by studying this commit. We didn't go directly
to j.u.l in this commit because that is a bigger change. Our logging
configuration is based on log4j1.2 and people are used to it. So it'd
be a much more fraught breaking change to do that conversion.
The plugin cli currently is extremely lenient, allowing most errors to
simply be logged. This can lead to either corrupt installations (eg
partially installed plugins), or confused users.
This change rewrites the plugin cli to have almost no leniency.
Unfortunately it was not possible to remove all leniency, due in
particular to how config files are handled.
The following functionality was simplified:
* The format of the name argument to install a plugin is now an official
plugin name, maven coordinates, or a URL.
* Checksum files are required, and only checked, for official plugins
and maven plugins. Checksums are also only SHA1.
* Downloading no longer uses a separate thread, and no longer has a timeout.
* Installation, and removal, attempts to be atomic. This only truly works
when no config or bin files exist.
* config and bin directories are verified before copying is attempted.
* Permissions and user/group are no longer set on config and bin files.
We rely on the users umask.
* config and bin directories must only contain files, no subdirectories.
* The code is reorganized so each command is a separate class. These
classes already existed, but were embedded in the plugin cli class, as
an extra layer between the cli code and the code running for each command.
This commit modifies the default setting for standard output in the
systemd configuration to the journal instead of /dev/null. This is to
address a user pain point where Elasticsearch would fail to start but
the error message would be sent to standard output and therefore
/dev/null leading to difficult-to-debug situations.
Both modules and integ-test-zip have integration tests (the latter being
the base rest tests). We can currently get odd behavior where
integ-test-zip's integ test does not shutdown its cluster before running
mdoule integ tests (and it then tries to shutdown all those clusters at
once after modules integ tests have run).
The underlying issue can be attributed to a bug in gradle with how cross project
mustRunAfter work with finalizers. This change works around this bug by
setting up mustRunAfter on the shutdown task itself.
This makes some minor improvements (does not fix all problems!)
It reorders unicast disco in elasticsearch.yml to be right after the network host,
for better locality.
It removes the warning (unreleased) about publish addresses, lets try to really discourage setting
that unless you need to (behind a proxy server). Most people should be fine with `network.host`
Finally it reorganizes the network docs page a bit:
We add a table of 4 "basic" settings at the very beginning:
* network.host
* discovery.zen.ping.unicast.hosts
* http.port
* transport.tcp.port
The first two being the most important, which addresses to bind and talk to, and the other two
being the port numbers.
The rest of the stuff I tried to simplify and reorder under "advanced" headers.
This is just a quick stab, I still think we need more effort into this thing, but we gotta start somewhere.
We currently use the full suite of packaged rest tests for each
distribution. We also used to run rest tests within core integ tests,
but this stopped working when we split out the test-framework, since the
test files are in there.
This change simplifies the code to run packaged rest tests just once,
for the integ-test-zip, and removes the unused rest tests from
test-framework. Distributions rest tests now check that all modules
were loaded.
This change attempts to simplify the gradle tasks for precommit. One
major part of that is using a "less groovy style", as well as being more
consistent about how tasks are created and where they are configured. It
also allows the things creating the tasks to set up inter task
dependencies, instead of assuming them (ie decoupling from tasks
eleswhere in the build).
Currently we use the "gradle project attachment plugin" to support
building elasticsearch as part of another project. However, this plugin
has a number of issues, a large part of which is requiring consistent
use of the projectsPrefix.
This change removes projectsPrefix, and adds support for a special
extra-plugins directory in the root of elasticsearch. Any projects
checked out within this directory will be automatically added to
elasticsearch.
