This new version permits omitting the space between the operator and the
boundary in a ruby-style version constraint, like ">1.0.0" instead of
"> 1.0.0".
The new provider installer code is using a new version constraint parser
because it produces better error messages than the one we were using
before. However, it has some cases where it returns errors that the old
parser (which was entirely regex-match-based) didn't catch.
In the long run we should consistently use the new parser everywhere, but
until then we'll avoid panicking then the two disagree, by returning
diagnostic messages instead of using MustParseVersionConstraints.
For now, we only hit these error cases if the user enters something that
the old parser allows but the new parser does not.
When initializing a configuration which refers to re-namespaced legacy
providers, we attempt to detect this and display a diagnostic message.
Previously this message would direct the user to run the 0.13upgrade
command, but without specifying in which directories.
This commit detects which modules are using the providers in question,
and for local modules displays a list of upgrade commands which specify
the source directories of these modules.
For remote modules, we display a separate list noting that they need to
be upgraded elsewhere, providing both the local module call name and the
module source address.
We previously had the module registry protocol documented only as an
undefined subset of the full API of the official registry implementation.
However, the vast majority of endpoints documented in the official API
docs are not needed for a headless third-party module registry that only
intends to make modules available to Terraform CLI.
To make this clearer to potential third-party implementors, and also for
consistency with how the provider registry protocol is now documented,
here we create a new page to describe the subset required for all
registries, and then explain in the docs for the offical API that
potential third-party implementors should refer to the new page instead.
The longer page describing the full API of the official implementations
remains for those who wish to write clients for that API, because it is
part of the API surface area for Terraform Cloud and Terraform Enterprise.
I also took this opportunity to address the fact that module addresses
don't really contain "provider names" at all, but rather than the fourth
field in the address is _conventionally_ an official provider name but
can really be any string that serves to differentiate multiple
implementations of the same abstraction. The new docs therefore refer to
this field as "system" rather than "provider".
The output destroy node only needs to connect to each of the output's
up-edges in order to be connected transitively to all of the outputs
dependencies. In large, highly-connected graphs, this may save
considerable time for each output.
The public functions for the graph UpEdges and DownEdges is returning
the internal Set from the graph, meaning that callers could
inadvertently corrupt the graph structure by editing the returned Sets.
Make UpEdges and DownEdges return a copy of the set, while retaining the
efficient no-copy behavior for internal callers.
The TargetsTransformer ignored resource indices before expansion could
happen, but was not handling module indices. Ensure that we collapse all
pre-expansion addresses to "configuration" addresses, with no module or
resource keys.
If the last step in a module target is an unkeyed instance, and it's
being compared against keyed instances, we have to assume it was
intended to be used as a Module rather than a ModuleInstance.
Providers can be required from multiple sources. The previous
implementation of the providers sub-command displayed only a flat list
of provider requirements, which made it difficult to see which modules
required each provider.
This commit reintroduces the tree display of provider requirements, and
adds a separate output block for providers required by existing state.
I feel the current confirmation prompt for 0.13upgrade command is
ambiguous what is expected. Actually, when I used it for the first time,
I cancelled it by typing `y` instead of `yes`.
I believe it would be great if the 0.13upgrade command tell us the
expected value for confirmation like 0.12upgrade.
* addrs: detect builtin provider when parsing legacy provider string
The ParseLegacyAbsProviderConfig was not detecting builtin providers
("terraform"), which caused issues for all users with 0.12 state and
the "terraform_remote_state" data source. Since "terraform" is the only
built-in provider this adds a very simple check to the parser so it
properly returns the builtin FQN.
* add tests to the addrs package
Most of the targets in the Makefile have not been used in either CI or
the normal development workflow for some time. Removing them clarifies
that the expected way to build Terraform locally is simple: go install.
Remaining targets:
- fmtcheck, generate: these are used in CI to verify that the code is
correctly formatted and that generate has been run appropriately
- protobuf: referenced in CONTRIBUTING.md as the simplest way to build
the proto files
- website, website-test: used to compile and test the local website in
isolation from the terraform-website repo
