As per the new licensing change for Elasticsearch and Kibana this commit
moves existing Apache 2.0 licensed source code to the new dual license
SSPL+Elastic license 2.0. In addition, existing x-pack code now uses
the new version 2.0 of the Elastic license. Full changes include:
- Updating LICENSE and NOTICE files throughout the code base, as well
as those packaged in our published artifacts
- Update IDE integration to now use the new license header on newly
created source files
- Remove references to the "OSS" distribution from our documentation
- Update build time verification checks to no longer allow Apache 2.0
license header in Elasticsearch source code
- Replace all existing Apache 2.0 license headers for non-xpack code
with updated header (vendored code with Apache 2.0 headers obviously
remains the same).
- Replace all Elastic license 1.0 headers with new 2.0 header in xpack.
Opt-in buildSrc for automatic formatting. This required a config tweak
in order to pick up all the Java sources, and as a result more files are
now found in the Enrich plugin, that were previously missed.
Following on from the formatting, improve some code's layout, most notably by
replacing a number of String concatentations with String.format().
Closes#48724. Update `.editorconfig` to make the Java settings the default
for all files, and then apply a 2-space indent to all `*.gradle` files.
Then reformat all the files.
Testclusters currently provides protection from clusters living past the
life of a build by adding a shutdown hook to java. While this works in
some cases, it does not cover all cases like where the daemon is killed
with SIGKILL.
To handle these other cases, this commit replaces the shutdown hooks with
a separate process (one per build) that manages reaping external services
if gradle dies.
