We sign our official plugins yet this is not well-advertised and not at
all consumed during plugin installation. For plugins that are installed
over the intertubes, verifying that the downloaded artifact is signed by
our signing key would establish both integrity and validity of the
downloaded artifact. The chain of trust here is simple: our installable
artifacts (archive and package distributions) so that if a user trusts
our packages via their signatures, and our plugin installer (which would
be executing trusted code) verifies the downloaded plugin, then the user
can trust the downloaded plugin too. This commit adds verification of
official plugins downloaded during installation. We do not add
verification for offline plugin installs; a user can download our
signatures and verify the artifacts themselves.
This commit also needs to solve a few interesting challenges. One of
these is that we want the bouncy castle JARs on the classpath only for
the plugin installer, but not for the runtime
Elasticsearch. Additionally, we want these JARs to not be present for
the JAR hell checks. To address this, we shift these JARs into a
sub-directory of lib (lib/tools/plugin-cli) that is only loaded for the
plugin installer, and in the plugin installer we filter any JARs in this
directory from the JAR hell check.
If you have an unusual umask (e.g., 0002) and clone the GitHub
repository then files that we stick into our packages like the
README.textile and the license will have a file mode of 0664 on disk yet
we expect them to be 0644. Additionally, the same thing happens with
compiled artifacts like JARs. We try to set a default file mode yet it
does not seem to take everywhere. This commit adds explicit file modes
in some places that we were relying on the defaults to ensure that the
built artifacts have a consistent file mode regardless of the underlying
build host.
This commit removes xpack from being a meta-plugin-as-a-module.
It also fixes a couple tests which were missing task dependencies, which
failed once the gradle execution order changed.
With the opening of xpack, we still retained a run task within
:x-pack:plugin. However, the root level run task also runs with the
default distribution. This change removes the extra run task inside
xpack in favor of using the root level task, and moves the
license/configuration code for run into the main run configuration.
Adds tasks that check that the all jars that we build have LICENSE.txt
and NOTICE.txt files and that the files are correct. Sets check to
depend on these task.
This is mostly there for extra parnoia because we automatically
configure all Jar tasks to include the LICENSE.txt and NOTICE.txt
files anyway. But it is quite possible to add configuration to those
tasks that would override either file.
This causes check to depend on several more things than it used to.
Take, for example, javadoc:
check depends on the new verifyJavadocJarNotice which depends on
extractJavadocJar which depends on javadocJar which depends on
javadoc, this check now depends on javadoc.
This commit adds some build time checks that the archive distributions
and package distributions contain the appropriate license and notice
files, and the package distributions contain the appropriate license
metadata.
This commit adds the distribution type to the startup scripts so that we
can discern from log output and the main response the type of the
distribution (deb/rpm/tar/zip).
This commit moves the apache and elastic license files into a new
root level `licenses` directory and rewrites the top level LICENSE.txt
to clarify the repository has a mix of apache and elastic licensed code.
This commit adds license metadata to rpm and deb packages. Additionally,
it makes the copyright file for deb files follow the machine readable
specification, and sets the correct license text based on the oss vs
default deb packages.
This commit adds the distribution flavor (default versus oss) to the
build process which is passed through the startup scripts to
Elasticsearch. This change will be used to customize the message on
attempting to install/remove x-pack based on the distribution flavor.
This commit makes x-pack a module and adds it to the default
distrubtion. It also creates distributions for zip, tar, deb and rpm
which contain only oss code.
This is a follow up to a previous change which set the error file path
for the package distributions. The observation here is that we always
set the working directory of Elasticsearch to the root of the
installation (i.e., Elasticsearch home). Therefore, we can specify the
error file path relative to this directory and default it to the logs
directory, similar to the package distributions.
This is a follow up to a previous change which set the heap dump path
for the package distributions. The observation here is that we always
set the working directory of Elasticsearch to to the root of
installation (i.e., Elasticsearch home). Therefore, we can specify the
heap dump path relative to this directory and default it to the data
directory, similar to the package distributions.
This commit adds a JVM flag to ensure that the JVM fatal error logs land
in the default log directory. Users that wish to use an alternative
location should change the path configured here.
This commit moves the distribution specific tasks into the respective
archives and packages builds. The collocation of common and distribution
specific tasks make it much easier to reason about what is expected in a
particular distribution.
This commit adds intermediate gradle projects for archive based
distributions (zip, tar) and package based distributions (rpm, deb). The
grouping allows the common distribution build file to be considerably
shorter and clearly separated from the common zip/tar and rpm/deb
configuration.
In order to build a plugin that extends the painless whitelist, the spi
classes must be available to the plugin at compile time. This commit
moves the spi classes into a separate jar which will be published. Any
plugin authors whiching to extend painless through spi would then add a
compileOnly dependency on this jar.
Otherwise newer versions of Gradle will see the outputs as stale and
remove the directory between having created the directory and copying
files into the directory (leading to the directory being created again,
this time missing some sub-directories).
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 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.

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 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.

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

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)

This commit changes the default heap size to 1 GB. Experimenting with
elasticsearch is often done on laptops, and 1 GB is much friendlier to
laptop memory. It does put more pressure on the gc, but the tradeoff is
a smaller default footprint. Users running in production can (and
should) adjust the heap size as necessary for their usecase.
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.

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.

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.

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.
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.
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.
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.
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.
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.
Today when running gradle clean
:distribution:(integ-test-zip|tar|zip):assemble, the created archive
distribution will be missing the empty plugins directory. This is
because the empty plugins folder created in the build folder for the
copy spec task is created during configuration and then is later wiped
away by the clean task. This commit addresses this issue, by pushing
creation of the directory out of the configuration phase.

Today when installing Elasticsearch from an archive distribution (tar.gz
or zip), an empty plugins folder is not included. This means that if you
install Elasticsearch and immediately run elasticsearch-plugin list, you
will receive an error message about the plugins directory missing. While
the plugins directory would be created when starting Elasticsearch for
the first time, it would be better to just include an empty plugins
directory in the archive distributions. This commit makes this the
case. Note that the package distributions already include an empty
plugins folder.
