Alisdair McDiarmid	1fdcbc4825	command: Fix 0.13upgrade bug with multiple blocks ... If a configuration had multiple blocks in the versions.tf file, it would be added to the `rewritePaths` list multiple times. We would then remove it from this slice, but only once, and so the output file would later be rewritten to remove the required providers block. This commit uses a set instead of a list to prevent this case, and adds a regression test.	6 years ago
Alisdair McDiarmid	a740b739e0	command: Change 0.13upgrade default to versions.tf ... Instead of using providers.tf as the default output file for the upgrader, we now default to versions.tf. This means that if the configuration has no `required_providers` blocks at all, or has multiple, the provider version requirements will be stored in the versions.tf file. We now also update the versions.tf file to set a `required_version` attribute in the first `terraform` block, with value ">= 0.13". This is similar to the behaviour of the 0.12upgrade command, and signals that the configuration should not be used with older versions of Terraform.	6 years ago
Alisdair McDiarmid	ae98bd12a7	command: Rework 0.13upgrade sub-command ... This commit implements most of the intended functionality of the upgrade command for rewriting configurations. For a given module, it makes a list of all providers in use. Then it attempts to detect the source address for providers without an explicit source. Once this step is complete, the tool rewrites the relevant configuration files. This results in a single "required_providers" block for the module, with a source for each provider. Any providers for which the source cannot be detected (for example, unofficial providers) will need a source to be defined by the user. The tool writes an explanatory comment to the configuration to help with this.	6 years ago
