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
script fails. If systemd-sysctl is masked then trying to restart the
systemd-sysctl service to pick up the changes to vm.max_map_count will
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
support, although we never tested this anywhere in CI. Since we do not
formally support this, and 32-bit usage is very low, we have elected to
no longer maintain 32-bit support. This commit removes any implication
of 32-bit support.

This commit removes the default path settings for data and logs. With
this change, we now ship the packages with these settings set in the
elasticsearch.yml configuration file rather than going through the
default.path.data and default.path.logs dance that we went through in
the past.

This commit removes path.conf as a valid setting and replaces it with a
command-line flag for specifying a non-default path for configuration.

When JAVA_HOME is not set we try to detect the location of Java. If its
location contains a space, due to a lack of quoting we will be
unsuccessful in invoking Java. This commit adds the necessary quoting to
handle this case.

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
from LoggedExec so that the output of the checkout command is
shown. This enables us to see the SHA used for the checkout which can be
useful when debugging a BWC break.

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.
Relates #24861
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
loading a shaded version of Jansi provided by Jython. This plugin has
been removed so these hacks are no longer necessary.
Relates #24681
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
common exception sites. Even though these sites are common, we'd
still like the exceptions to debug them.
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.

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
automatically be correct for whatever system the build is running on.
closes#23784
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.
