* Fix output malformed when wrapper enabled
Presently using a command such as `terraform output -json | jq` does not
work with the wrapper enabled, as it is by default.
In order to consume terraform's output having set it up with this
Action, it is necessary either to disable the wrapper (`with:
terraform_wrapper: false`) or run it in its own Actions step with an
explicit `id` (e.g. `id: foo`) so that it can be referred to and consumed
(`${{steps.foo.outputs.stdout}}` et al.) in later steps.
This seems to be the result of much confusion (issues passim) and is not
at all easy (#338) to debug/diagnose and come to the realisation that
it's due to the wrapper, or even that such a thing exists.
@austinvalle identified the issue as being due to the `@actions/exec`
package writing the spawned command to stdout (along with then its
actual stdout). This has previously been reported upstream in
actions/toolkit#649; I've proposed actions/toolkit#1573 to fix it.
This commit aims to address the issue for `setup-terraform` in the
meantime by silencing `@actions/exec` and then writing out to stdout &
stderr from the listener buffers, which it writes to without this
additional logging.
Closes #20, #80, #85, #149, #338, and probably more.
* add test for stdout with jq
* update test name
* remove debug lines and add changelog
* add additional note about the bug fix to wrapper

body: The wrapper around the installed Terraform binary has been fixed to return the
|
|
exact STDOUT and STDERR from Terraform when executing commands. Previous versions
|
|
of setup-terraform may have required workarounds to process the STDOUT in bash,
|
|
such as filtering out the first line or selectively parsing STDOUT with jq. These
|
|
workarounds may need to be adjusted with `v3.0.0`, which will now return just the
|
|
STDOUT/STDERR from Terraform with no errant characters/statements.
