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".
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
The recursive call should only return immediately on error.
The switch statement to find the current path should not use
ReferenceOutside, as we are getting the path for configuration, not for
references. This case would not have been taken currently, since all
GraphNodeReferenceOutside are also GraphNodeModulePath.
Diagnostics where the highlight range has an empty overlap with a line
would skip lines of the output. This is because if two ranges abut each
other, they can be considered to overlap, but that overlap is empty.
This results in an edge case in the diagnostic printer which causes the
line not to be printed.
* Update error message for apply validation
Add a hint that the validation failure has occurred at the root of the resource
schema to the error message. This is because the root resource has an empty
path when being validated and the path is being relied upon to provide context
into the error message.
Currently the example config for the Consul backend uses a live Consul demo cluster at `demo.consul.io`. This results in TF state with sensitive information and all being stored on a public site when users just copy and paste the config. This PR changes it so that the config address isn't the public demo cluster.
* backend/remote: do not panic if PrepareConfig or Configure receive null
objects
If a user cancels (ctrl-c) terraform init while it is requesting missing
configuration options for the remote backend, the PrepareConfig and
Configure functions would receive a null cty.Value which would result in
panics. This PR adds a check for null objects to the two functions in
question.
Fixes#23992
During refresh, data sources need to know if their parent modules have
depends_on configured at all. Pass this info back through the search for
depends_on resources, and delay refresh when it's set.
Resources that are not yet created will not be in the graph during
refresh, and therefore cannot be attached to the data source nodes. In
this case we still need to indicate if there are depends_on entries
inherited from the module call, which we can do with the forceDependsOn
field.
We'll need this again for getting the transitive depends_on references
from parent module calls. This is needed to inform us how to handle data
sources during refresh and plan.
