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.
We recently got a run command with gradle, but it is sometimes useful to
run ES with a specific plugin. This is a start, by making each esplugin
have a run command which installs the plugin and runs elasticsearch in
the foreground.
run.sh and run.bat were calling out to the old maven build system.
This is no longer in place, so we've created new gradle tasks to
start an elasticsearch node from the current codebase.

Gradle defaults to tgz extension when tar is compressed. This changes
the tar distribution back to tar.gz. Note that this also means the maven
packaging type is now tar.gz.
This change removes the leftover pom files. A couple files were left for
reference, namely in qa tests that have not yet been migrated (vagrant
and multinode). The deb and rpm assemblies also still exist for
reference when finishing their setup in gradle.

Add threadgroup isolation.
Code with `modifyThread` and `modifyThreadGroup` may only modify
its own threadgroup (or an ancestor of that). This enforces
what is intended by the ThreadGroup class.
This has two immediate implications:
1. Code without these permissions (scripts) may not create or mess with threads
2. ES application threads cannot mess with Java system threads
ES puts all application threads in one single group today, but in the future
this can be organized better, and we will have more isolation in the system.
