Many apps deployed to Heroku require that multiple buildpacks be
configured in a particular order to operate correctly.
This updates the builtin Heroku provider's app resource to support
configuring buildpacks and the related documentation in the website.
Similar to config vars, externally set buildpacks will not be altered if
the config is not set.
Change the `RetryFunc` from a plain `error` return type to a
specialized `RetryError` which must decide whether it is
retryable or not.
Add `RetryableError` / `NonRetryableError` factory functions that
callers are meant to use to build up these errors.
This makes it eminently clear whether or not a given error is
retryable from inside the client code.
Goal here is to _not_ change any behavior, simply reflect the
existing behavior with the new, clearer, API.
* Randomize app name in test
* Return error and don't panic when there is a problem
It's possible there may still be an underlying problem that caused the
error that made the cert leak in the first place - this should help us
diagnose it.
It seems there are 4 locations left that use the `helper/multierror`
package, where the rest is TF settled on the `hashicorp/go-multierror`
package.
Functionally this doesn’t change anything, so I suggest to delete the
builtin version as it can only cause confusion (both packages have the
same name, but are still different types according to Go’s type system.
Fixes the following vet reports:
builtin/providers/heroku/resource_heroku_app.go:192: arg vs for printf verb %s of wrong type: bool
builtin/providers/heroku/resource_heroku_app.go:198: arg vs for printf verb %s of wrong type: bool
Before all providers were using the helper.Schema approach the helper
function had these names. Now they all use names consistent with the Go
naming conventions except for these last few…
The default stack changed from ‘cedar’ to ‘cedar-14’, so updated the
acceptance tests to reflect this.
Updating the schema makes testing easier and gives you a way to
configure the provider using env variables. It also makes the provider
more inline following the TF 0.2 approach.
