The error diagnostic shown when legacy state contains resources from
in-house providers has changed, so update references to it in the 0.13
upgrade guide.
When init attempts to install a legacy provider required by state and
fails, but another provider with the same type is successfully
installed, this almost definitely means that the user is migrating an
in-house provider. The solution here is to use the `terraform state
replace-provider` subcommand.
This commit makes that next step clearer, by detecting this specific
case, and displaying a list of commands to fix the existing state
provider references.
Diagnostic detail lines sometimes contain lines which include commands
suggested for the user to execute. By convention, these start with
leading whitespace to indicate that they are not prose.
This commit changes the diagnostic formatter to wrap each line of the
detail separately, and skips word wrapping for lines prefixed with
space. This prevents ugly and confusing wrapping of long command lines.
Although we have in this same directory the protocol buffers schemas for
the static parts of the provider wire protocol, many of the protocol
messages include DynamicValue messages that are presented in a nested
dynamic serialization format.
That format was previously not documented, and was thus defined only by
the implementation. Terraform happens to use a third-party library to
implement parts of this encoding, which means that the rules were even
harder to track down from reading the code.
Regardless of how Terraform happens to implement its serialization and
deserialization of DynamicValue, it's the wire format that is contractual
and so this document is an implementation-agnostic description of the
mapping rules for serializing any Terraform Language value by reference to
a provider-defined schema.
All future changes to the rules described in here must be backward
compatible until protocol major version 6, which is not currently planned.
This pull reverts a recent change to backend/local which created two context, one with and one without state. Instead I have removed the state entirely from the validate graph (by explicitly passing a states.NewState() to the validate graph builder).
This changed caused a test failure, which (ty so much for the help) @jbardin discovered was inaccurate all along: the test's call to `Validate()` was actually what was removing the output from state. The new expected test output matches terraform's actual behavior on the command line: if you use -target to destroy a resource, an output that references only that resource is *not* removed from state even though that test would lead you to believe it did.
This includes two tests to cover the expected behavior:
TestPlan_varsUnset has been updated so it will panic if it gets more than one request to input a variable
TestPlan_providerArgumentUnset covers #26035Fixes#26035, #26027
If a provider changes namespace in the registry, we can detect this when
running the 0.13upgrade command. As long as there is a version matching
the user's constraints, we now use the provider's new source address.
Otherwise, warn the user that the provider has moved and a version
upgrade is necessary to move to it.
When the output subcommand is called with no arguments, and there are no
outputs to show, we previously rendered an error message but returned a
non-error status code. This is confusing.
This commit changes the text UI to use a warning diagnostic, which makes
it clearer that this is a non-error situation. We do not change the exit
code or the text of the warning, so hopefully this is not considered a
breaking change.
When calling createEmptyBlocks, we only intend to process legacy SDK
blocks (NestingList or NestingSet), but the function also needs to pass
through NestingSingle block types untouched. To do so we must only look
up the container's element type after we've established that the block
is backed by a container.
We previously had this just stubbed out because it was a stretch goal for
the v0.13.0 release and it ultimately didn't make it in.
Here we fill out the existing stub -- with a minor change to its interface
so it can access credentials -- with a client implementation that is
compatible with the directory structure produced by the
"terraform providers mirror" subcommand, were the result to be published
on a static file server.
Earlier we introduced a new package hashing mechanism that is compatible
with both packed and unpacked packages, because it's a hash of the
contents of the package rather than of the archive it's delivered in.
However, we were using that only for the local selections file and not
for any remote package authentication yet.
The provider network mirrors protocol includes new-style hashes as a step
towards transitioning over to the new hash format in all cases, so this
new authenticator is here in preparation for verifying the checksums of
packages coming from network mirrors, for mirrors that support them.
For now this leaves us in a kinda confusing situation where we have both
NewPackageHashAuthentication for the new style and
NewArchiveChecksumAuthentication for the old style, which for the moment
is represented only by a doc comment on the latter. Hopefully we can
remove NewArchiveChecksumAuthentication in a future commit, if we can
get the registry updated to use the new hashing format.
When applying a backend config override file, we must not check for the
presence of all required fields, as the override can be a partial
configuration. It is only valid to check for required fields after all
overrides have been merged, which init already does.
