provider is not found.
Previously a user would see the following error even if terraform was
only searching the local filesystem:
"provider registry registry.terraform.io does not have a provider named
...."
This PR adds a registry-specific error type and modifies the MultiSource
installer to check for registry errors. It will return the
registry-specific error message if there is one, but if not the error
message will list all locations searched.
* internal/getproviders: apply case normalizations in ParseMultiSourceMatchingPatterns
This is a very minor refactor which takes advantage of addrs.ParseProviderPart case normalization to normalize non-wildcard sources.
* internal/providercache: verify that the provider protocol version is
compatible
The public registry includes a list of supported provider protocol
versions for each provider version. This change adds verification of
support and adds a specific error message pointing users to the closest
matching version.
Due to other pressures at the time this was implemented, it was tested
only indirectly through integration tests in other packages.
This now introduces tests for the two main entry points on the
MultiSource, along with its provider-address pattern matching logic.
This does not yet include thorough tests for
ParseMultiSourceMatchingPatterns, because that function still needs some
adjustments to do the same case folding as for normal provider address
parsing, which will follow in a latter commit along with suitable tests.
With that said, the tests added here do _indirectly_ test the happy path
of ParseMultiSourceMatchingPatterns, so we have some incomplete testing
of that function in the meantime.
