Previously, we were just handing off the absolute path produced by the sourcebundle struct. But that's no good, because the value doesn't stay consistent between plan and apply when running under tfc-agent. (It uses working directories named after the unique job ID.) It also doesn't match the documentation, which describes these as relative paths. This was preventing people from uploading module-provided files to create aws lambda functions, for example. This commit addresses that by converting the source-bundle provided module path to a relative path (relative to Terraform's working directory). In tfc-agent for stacks runs, that ends up being the directory directly above the sourcebundle directory, and all the paths below that are consistent between plan and apply.

@crw No, to the best of my understanding it doesn't have anything to do with that request at all. |
