* internal/initwd: Allow deprecated relative module paths
In Terraform 0.11 we deprecated this form but didn't have any explicit
warning for it. Now we'll still accept it but generate a warning. In a
future major release we will drop this form altogether, since it is
ambiguous with registry module source addresses.
This codepath is covered by the command/e2etest suite.
* e2e: Skip copying .exists file, if present
We use this only in the "empty" test fixture in order to let git know that
the directory exists. We need to skip copying it so that we can test
"terraform init -from-module=...", which expects to find an empty
directory.
* command/e2etests: Re-enable and fix up the e2etest "acctests"
We disabled all of the tests that accessed remote services like the
Terraform Registry while they were being updated to support the new
protocols we now expect. With those services now in place, we can
re-enable these tests.
Some details of exactly what output we print, etc, have intentionally
changed since these tests were last updated.
* e2e: refactor for modern states and plans
* command/e2etest: re-enable e2etests and update for tf 0.12 compatibility
plugin/discovery: mkdirAll instead of mkdir when creating cache dir
In a couple places in tests we execute a child "go build" to make a helper
program. Now that we're running in module mode, "go build" will normally
default to downloading and caching dependencies, which we don't want
because we're still using vendoring for the moment.
Therefore we need to instruct these child builds to use vendoring too,
avoiding the need to download all of the dependencies and ensuring that
we'll be building with the same dependencies that we'd use for a normal
build.
