* Refactor provider validation into separate func & recurse
Refactors the validate provider functions into a separate function
that can recursively search above a module to check and see if
any parents of the module contain count/for_each configs to be
considered
If depends_on is allowed for outputs, we should validate that the
expressions are valid. Since outputs are always evaluated, and
validation is just done by this evaluation, we can check the
depends_on validation during evaluation too.
There aren't going to be any nodes specifically for module call
instances during plan, so we have to switch the reference subject to the
general module call.
This document on building release-style binaries is out of date (`make
bin` no longer works) and does not fully reflect how releases of
Terraform are built. Since release builds are not reproducible, this
information is more likely to mislead users trying to build development
binaries than it is to be useful.
The positional argument passed to apply was once used to specify a
source for a Terraform module to fetch and initialize (#337). This
functionality was removed from the init command later (#15032) but not
completely removed from apply.
This code was non-functional but largely not harmful, except for a very
specific case: when passing an absolute path to a plan file as the
positional argument on Windows, the getter.Detect code would incorrectly
interpret the path as a URL. This caused init to fail and the apply
command would exit with code 1 but without diagnostics.
This commit removes this codepath, which fixes this bug, and should
otherwise have no effect on the supported behaviour of apply.
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".
