Replace compile configuration usage with api (7.x backport) (#58721)
* Replace compile configuration usage with api (#58451)

- Use java-library instead of plugin to allow api configuration usage
- Remove explicit references to runtime configurations in dependency declarations
- Make test runtime classpath input for testing convention
  - required as java library will by default not have build jar file
  - jar file is now explicit input of the task and gradle will ensure its properly build

* Fix compile usages in 7.x branch

Skip packaging test log file stashing once tests have failed (#58520)
When a packaging test completes, we move the elasticsearch logfile to
another location so that if the next test fails, we have just the
contents of the test that ran. However, once the test fails, we continue
trying to move this file in the subsequent calls to teardown when the
rest of the tests are skipped. This commit skips the teardown step once
we have marked the suite as failed.

Migrate plugin packaging tests to java (#58518)
This commit converts the bats tests for the plugin cli into the java
packaging test framework. The new tests only use the example plugin to
test the plugin cli. The tests for each individual plugin's contents
after being installed are handled by a new unit test for the plugin
installer added in #58287.

Enable TTY password OS tests, plus refactoring (#57759) (#58200)
* Enable TTY password OS tests, plus refactoring (#57759)

Two keystore tests were unintentionally ignored when the
password-protected keystore work was merged. I've reënabled those tests
here.

I've also refactored the test methods a little bit to reduce the API
surface: instead of having a "startElasticsearchTtyPassword" method and
a "startElasticsearchStandardInputPassword" method, I've made a single
"startElasticsearch" method with a "useTty" boolean argument.

* Separate daemonization and non-daemonization case for tty

Centos 6 uses a version of expect that kills the elasticsearch process
when it tries to daemonize. I will fix this in future work but for now
I'm replacing it with a todo.

Consolidate temp dir handling in packaging tests (#58292)
The packaging tests currently have a couple different ways of deciding
where temp files should be placed, and then sometimes used fixed file
or directory names within that dir. This commit conslidates some of that
temp dir handling by making it more compatible with the handling that
exists within the bats tests, where /tmp is not always appropriate due
to how systemd interacts with it. This commit also adds a utility
methhod for creating temp dirs, so as to ensure the new directory is
created as if a umask of 022 were used, which is not the case when using
Files.createTempDirectory without a set of permissions (it assumes 077).

Do not daemonize when testing error output in packaging tests (#56971) (#56997)
The packaging tests start elasticsearch in various ways. All of these
currently expect it is started asynchronously, yet some tests expect it
will fail to start and want to check the error output. This commit adds
a daemonize flag to the utility methods to start elasticsearch for such
cases, so that when the start method returns, all the error output
should already be available since the process will have exited.

Make windows JAVA_HOME handling consistent with linux (#55261) (#55362)
In bash, checking for whether an env variable exists uses the -z test,
against a stringified env var, so that the test is actually whether the
env var is empty, but not necessarily undefined. We use this to test
whether JAVA_HOME is set, to determine whether the bundled jdk should be
used. In windows, this test is an actual "undefined" check. This commit
brings the behavior on two systems in sync, opting to allow for an empty
JAVA_HOME in windows to indicate the bundled jdk should be used.

Remove deprecated third-party methods from tests (#55255) (#55269)
I've noticed that a lot of our tests are using deprecated static methods
from the Hamcrest matchers. While this is not a big deal in any
objective sense, it seems like a small good thing to reduce compilation
warnings and be ready for a new release of the matcher library if we
need to upgrade. I've also switched a few other methods in tests that
have drop-in replacements.

Use task avoidance with forbidden apis (#55034)

tasks are aggressively created by the plugin. In forbidden apis 3.0, we
will get task avoidance

need to ourselves use the same task avoidance mechanisms to not trigger
these task creations. This commit does that for our foribdden apis

In particular, I noticed that `Files.write(...)` when passed a list will

making it easier to use than FileUtils.append. It's even available from

Also, in the Allocators class, a number of methods declared thrown exceptions that IntelliJ reported were never thrown, and as far as I could see this is true, so I removed the exceptions.

Filter empty lines from "docker ls" response (#52081)
* Filter empty lines from docker ls response

In order to cut down on test time, our docker/vagrant tests build the
docker image outside of the vagrant VM. When we get around to launching
the Vagrant VM, we mount that already-built docker image to a known
location. At that point, we need to load the docker image. But we only
want to load it once. As we're running tests, we use "docker ls" to
check whether the local image is loaded for use. Empty output from the
particular ls invocation means no image is loaded.

There was a bug in how we checked this. In Java, splitting an empty
string will yield an array containing one empty string. So when we're
counting the output from the docker ls command, we need to filter out
empty lines in order to proceed to loading the image for docker tests.

Introduce jvm.options.d for customizing JVM options (#51882)
This commit introduces the ability to override JVM options by adding
custom JVM options files to a jvm.options.d directory. This simplifies
administration of Elasticsearch by not requiring administrators to keep
the root jvm.options file in sync with changes that we make to the root
jvm.options file. Instead, they are not expected to modify this file but
instead supply their own in jvm.options.d. In Docker installations, this
means they can bind mount this directory in. In future versions of
Elasticsearch, we can consider removing the root jvm.options file
(instead, providing all options there as system JVM options).

Add file existence matchers in packaging tests (#52090)

Password-protected Keystore Feature Branch PR (#51123) (#51510)
* Reload secure settings with password (#43197)

If a password is not set, we assume an empty string to be
compatible with previous behavior.
Only allow the reload to be broadcast to other nodes if TLS is
enabled for the transport layer.

* Add passphrase support to elasticsearch-keystore (#38498)

This change adds support for keystore passphrases to all subcommands
of the elasticsearch-keystore cli tool and adds a subcommand for
changing the passphrase of an existing keystore.
The work to read the passphrase in Elasticsearch when
loading, which will be addressed in a different PR.

Subcommands of elasticsearch-keystore can handle (open and create)
passphrase protected keystores

When reading a keystore, a user is only prompted for a passphrase
only if the keystore is passphrase protected.

When creating a keystore, a user is allowed (default behavior) to create one with an
empty passphrase

Passphrase can be set to be empty when changing/setting it for an
existing keystore

Relates to: #32691
Supersedes: #37472

* Restore behavior for force parameter (#44847)

Turns out that the behavior of `-f` for the add and add-file sub
commands where it would also forcibly create the keystore if it
didn't exist, was by design - although undocumented.
This change restores that behavior auto-creating a keystore that
is not password protected if the force flag is used. The force
OptionSpec is moved to the BaseKeyStoreCommand as we will presumably
want to maintain the same behavior in any other command that takes
a force option.

*  Handle pwd protected keystores in all CLI tools  (#45289)

This change ensures that `elasticsearch-setup-passwords` and
`elasticsearch-saml-metadata` can handle a password protected
elasticsearch.keystore.
For setup passwords the user would be prompted to add the
elasticsearch keystore password upon running the tool. There is no
option to pass the password as a parameter as we assume the user is
present in order to enter the desired passwords for the built-in
users.
For saml-metadata, we prompt for the keystore password at all times
even though we'd only need to read something from the keystore when
there is a signing or encryption configuration.

* Modify docs for setup passwords and saml metadata cli (#45797)

Adds a sentence in the documentation of `elasticsearch-setup-passwords`
and `elasticsearch-saml-metadata` to describe that users would be
prompted for the keystore's password when running these CLI tools,
when the keystore is password protected.

* Elasticsearch keystore passphrase for startup scripts (#44775)

This commit allows a user to provide a keystore password on Elasticsearch
startup, but only prompts when the keystore exists and is encrypted.

The entrypoint in Java code is standard input. When the Bootstrap class is
checking for secure keystore settings, it checks whether or not the keystore
is encrypted. If so, we read one line from standard input and use this as the
password. For simplicity's sake, we allow a maximum passphrase length of 128
characters. (This is an arbitrary limit and could be increased or eliminated.
It is also enforced in the keystore tools, so that a user can't create a
password that's too long to enter at startup.)

In order to provide a password on standard input, we have to account for four
different ways of starting Elasticsearch: the bash startup script, the Windows
batch startup script, systemd startup, and docker startup. We use wrapper
scripts to reduce systemd and docker to the bash case: in both cases, a
wrapper script can read a passphrase from the filesystem and pass it to the
bash script.

In order to simplify testing the need for a passphrase, I have added a
has-passwd command to the keystore tool. This command can run silently, and
exit with status 0 when the keystore has a password. It exits with status 1 if
the keystore doesn't exist or exists and is unencrypted.

A good deal of the code-change in this commit has to do with refactoring
packaging tests to cleanly use the same tests for both the "archive" and the
"package" cases. This required not only moving tests around, but also adding
some convenience methods for an abstraction layer over distribution-specific
commands.

* Adjust docs for password protected keystore (#45054)

This commit adds relevant parts in the elasticsearch-keystore
sub-commands reference docs and in the reload secure settings API
doc.

* Fix failing Keystore Passphrase test for feature branch (#50154)

One problem with the passphrase-from-file tests, as written, is that
they would leave a SystemD environment variable set when they failed,
and this setting would cause elasticsearch startup to fail for other
tests as well. By using a try-finally, I hope that these tests will fail
more gracefully.

It appears that our Fedora and Ubuntu environments may be configured to
store journald information under /var rather than under /run, so that it
will persist between boots. Our destructive tests that read from the
journal need to account for this in order to avoid trying to limit the
output we check in tests.

* Run keystore management tests on docker distros (#50610)

* Add Docker handling to PackagingTestCase

Keystore tests need to be able to run in the Docker case. We can do this
by using a DockerShell instead of a plain Shell when Docker is running.

* Improve ES startup check for docker

Previously we were checking truncated output for the packaged JDK as
an indication that Elasticsearch had started. With new preliminary
password checks, we might get a false positive from ES keystore
commands, so we have to check specifically that the Elasticsearch
class from the Bootstrap package is what's running.

* Test password-protected keystore with Docker (#50803)

This commit adds two tests for the case where we mount a
password-protected keystore into a Docker container and provide a
password via a Docker environment variable.

We also fix a logging bug where we were logging the identifier for an
array of strings rather than the contents of that array.

* Add documentation for keystore startup prompting (#50821)

When a keystore is password-protected, Elasticsearch will prompt at
startup. This commit adds documentation for this prompt for the archive,
systemd, and Docker cases.

* Warn when unable to upgrade keystore on debian (#51011)

For Red Hat RPM upgrades, we warn if we can't upgrade the keystore. This
commit brings the same logic to the code for Debian packages. See the
posttrans file for gets executed for RPMs.

* Restore handling of string input

Adds tests that were mistakenly removed. One of these tests proved
we were not handling the the stdin (-x) option correctly when no
input was added. This commit restores the original approach of
reading stdin one char at a time until there is no more (-1, \r, \n)
instead of using readline() that might return null

* Apply spotless reformatting

* Use '--since' flag to get recent journal messages

When we get Elasticsearch logs from journald, we want to fetch only log
messages from the last run. There are two reasons for this. First, if
there are many logs, we might get a string that's too large for our
utility methods. Second, when we're looking for a specific message or
error, we almost certainly want to look only at messages from the last
execution.

Previously, we've been trying to do this by clearing out the physical
files under the journald process. But there seems to be some contention
over these directories: if journald writes a log file in between when
our deletion command deletes the file and when it deletes the log
directory, the deletion will fail.

It seems to me that we might be able to use journald's "--since" flag to
retrieve only log messages from the last run, and that this might be
less likely to fail due to race conditions in file deletion.

Unfortunately, it looks as if the "--since" flag has a granularity of
one-second. I've added a two-second sleep to make sure that there's a
sufficient gap between the test that will read from journald and the
test before it.

* Use new journald wrapper pattern

* Update version added in secure settings request

Instead, we can use the cursor capablity of journald to retrieve journal

to interfere with the underlying file operations of journald.

Handle renaming the README (#50404) (#50406)
We renamed README.textile to README.asciidoc but a bunch of tests and
the package build itself still pointed at the old name. This switches
them the new name.

Refactor environment variable processing for Docker (#50221)
Backport of #49612.

The current Docker entrypoint script picks up environment variables and
translates them into -E command line arguments. However, since any tool
executes via `docker exec` doesn't run the entrypoint, it results in
a poorer user experience.

Therefore, refactor the env var handling so that the -E options are
generated in `elasticsearch-env`. These have to be appended to any
existing command arguments, since some CLI tools have subcommands and
-E arguments must come after the subcommand.

Also extract the support for `_FILE` env vars into a separate script, so
that it can be called from more than once place (the behaviour is
idempotent).

Finally, add noop -E handling to CronEvalTool for parity, and support
`-E` in MultiCommand before subcommands.

Simplify running tools in packaging tests (#49665) (#50110)
Running tools requires a shell. This should be the shell setup by the
base packaging tests, but currently tests must pass in their own shell.
This commit begins to make running tools easier by eliminating the shell
argument, instead keeping the shell as part of the Installation (which
can eventually be passed through from the test itself on installation).
The variable names for each tool are also simplified.
