This is needed to make it possible to use the scram-sha-256
authentication method for the pg backend. It's not easy to write
unit-tests for this since it requires a specific configuration of the
PostgreSQL server, I did test it manually thought and everything seems
to work like it should.
Closes https://github.com/hashicorp/terraform/issues/24016
The example configuration now uses Terraform 0.12+ syntax, and the
output examples are up to date with the current text UI. We also add an
explicit recommendation to use the `-json` option for a consistent and
stable output format, for use in automation.
When building a context, we read the dependency locks and ensure that
the provider requirements from the configuration can be satisfied.
If the configured requirements change such that the locks need to be
updated, we explain this and recommend running "terraform init".
This check is ignored for any providers which are locally marked as in
development. This includes unmanaged providers and those listed in the
provider installation `dev_overrides` block.
When logging is turned on, panicwrap will still see provider crashes and
falsely report them as core crashes, hiding the formatted provider
error. We can trick panicwrap by slightly obfuscating the error line.
Prior to Terraform 0.12 these two functions were the only way to construct
literal lists and maps (respectively) in HIL expressions. Terraform 0.12,
by switching to HCL 2, introduced first-class syntax for constructing
tuple and object values, which can then be converted into list and map
values using the tolist and tomap type conversion functions.
We marked both of these functions as deprecated in the Terraform v0.12
release and have since then mentioned in the docs that they will be
removed in a future Terraform version. The "terraform 0.12upgrade" tool
from Terraform v0.12 also included a rule to automatically rewrite uses
of these functions into equivalent new syntax.
The main motivation for removing these now is just to get this change made
prior to Terraform 1.0. as we'll be doing with various other deprecations.
However, a specific reason for these two functions in particular is that
their existence is what caused us to invent the idea of a "type expression"
as a distinct kind of expression in Terraform v0.12, and so removing them
now would allow potentially unifying type expressions with value
expressions in a future release.
We do not have any current specific plans to make that change, but one
potential motivation for doing so would be to take another attempt at a
generalized "convert" function which takes a type as one of its arguments.
Our previous attempt to implement such a function was foiled by the fact
that Terraform's expression validator doesn't have any way to know to
treat one argument of a particular function as special, and so it was
generating incorrect error messages. We won't necessarily do that, but
having these "list" and "map" functions out of the way leaves the option
open.
Core is only using the PrepareProviderConfig call for the validation
part of the method, but we should be re-validating the final config
immediately before Configure.
This change elects to not start using the PreparedConfig here, since
there is no useful reason for it at this point, and it would
introduce a functional difference between terraform releases that can be
avoided.
The validation for ignore_changes was too broad, and makes it difficult
to ignore changes in an attribute that the user does not want to set.
While the goal of ignore_changes is to prevent changes in the
configuration alone, we don't intend to break the use-case of ignoring
drift from the provider. Since we cannot easily narrow the validation to
only detect computed attributes at the moment, we can drop this error
altogether for now.
The documentation states that an explicit type conversion to set is needed, but it does not say why implicit type conversion does not work.

When rendering a set of version constraints to a string, we normalize
partially-constrained versions. This means converting a version
like 2.68.* to 2.68.0.
Prior to this commit, this normalization was done after deduplication.
This could result in a version constraints string with duplicate
entries, if multiple partially-constrained versions are equivalent. This
commit fixes this by normalizing before deduplicating and sorting.
This requires more GitHub token permissions than we have, and it's
inessential. The backport PRs should have reviews assigned to the
original PR author anyway.
When rendering planned output changes, we need to filter the plan's
output changes to ensure that only root module outputs which have
changed are rendered. Otherwise we will render changes for submodule
outputs, and (with concise diff disabled) render unchanged outputs also.
* The index must be non-negative integer
and added instructions on how to get the last value in the list.
* Typo fix
