Added locking support via blob leasing (requires that an empty state is
created before any lock can be acquired.
Added support for "environments" in much the same way as the S3 backend.
Equality of schema.Sets gets tricky when dealing with nested sets -
Set.Equal only superficially compares the underlying maps and hence any
sets nested under the root sets cause issues.
This adds a simple method, HashEqual, that does a top-level hash
comparison, helping to work around this without any complex re-invention
of things like reflect.DeepEqual.
Of course, in order to make effective use of this function, the user
needs to make sure they are properly hashing their nested sets, however
this is trivial with things like HashResource.
The go-plugin package now uses hclog. The default Logger has a level set
to Info, but all plugin output is relayed via Debug. Create a new named
logger for plugins with the level set to Trace so that all output comes
through.
#15596 set things up with the intent that the docker image build process
would be handled by the automated build system on dockerhub, but after
merging we found that it's impossible to change the source git repository
for an existing dockerhub repository.
To get away from the limitations of dockerhub, we intend to eventually
automate these builds in a separate CI system. Here we add some scripts
that would drive such an automated process. It's split into multiple steps
to allow for situations where the new version should not be tagged as
the latest, and to make it easier and safer to test the build script
while doing development on it.
Since this automated process doesn't yet exist, a wrapper script
release.sh is included to help run a local, manual build and deploy
process in the mean time. The README.md in the docker-release dir here
contains details on the intended usage.
This puts us on a version that has grpc protocol support. Although we're
not actually using that yet, the plugin has handshake changed slightly to
allow plugins to declare whether they use the old or new protocols, and
so this upgrade allows us to support plugins that were built against
newer versions of go-plugin that include this extra field in the
handshake.
This fixes#15756.
