This commit adds writing build metadata to the `check` command for each
bwc project. This ensures the files will be written if doing a general
`gradle check`, which is what CI intake jobs do. In later jobs like
bwcTest, the extra bwc-release-snapshot info is needed.
Note this commit also has a little cleanup of the output for the bwc
checkout, as it was plastering a git warning, instead of the real info
we care about (the refspec and commit that were used).
This commit adds a gradle project, set inside the root build.gradle,
which controls all our bwc tests. This allows for seamless (ie no errant
CI failures) backporting of behavior.
This adds an option to `ClusterConfiguration` to preserve the
`shared` directory when starting up a new cluster and switches
the `qa:full-cluster-restart` tests to use it rather than
disable the clean shared task.
Relates to #24846
These tests spin up two nodes of an older version of Elasticsearch,
create some stuff, shut down the nodes, start the current version,
and verify that the created stuff works.
You can run `gradle qa:full-cluster-restart:check` to run these
tests against the head of the previous branch of Elasticsearch
(5.x for master, 5.4 for 5.x, etc) or you can run
`gradle qa:full-cluster-restart:bwcTest` to run this test against
all "index compatible" versions, one after the other. For master
this is every released version in the 5.x.y version *and* the tip
of the 5.x branch.
I'd love to add more to these tests in the future but these
currently just cover the functionality of the `create_bwc_index.py`
script and start to cover the assertions in the
`OldIndexBackwardsCompatibilityIT` test.
