When parsing provider requirements we should check the type of the
source and version attributes rather than assuming that they are
strings. Otherwise an invalid attribute value will cause a panic.
In a recent PR, we changed the provider requirements code to permit
per-module requirements gathering, to enhance the provider command
output. This had an incorrect implementation of recursive requirements
gathering for the normal case, which resulted in only depth-1 modules
being inspected.
This commit fixes the broken recursion and adds a grandchild module to
the unit tests as test coverage. This also demanded fixing the
testNestedModuleConfigFromDir helper function to cope with nested
modules in test configs.
If a data source is storing a value that doesn't comply precisely with
the schema, it will now show up as a perpetual diff during plan.
Since we can easily detect if there is no resulting change from the
stored value, rather than presenting a planned read each time, we can
change the plan to a NoOp and log the incongruity as a warning.
Some of the tests in the command package were running directly on the
fixture directories, and modifying or locking files within them. This
could cause state to leak between tests.
This commit cleans up all such cases that I could find.
We previously covered everything about using providers on a single page,
but that was getting unwieldy already and we now have a lot more to
discuss with v0.13 introducing a new source address syntax and some other
concepts.
Here we split the provider-related content into two parts: "Provider
Requirements" covers how to find and declare dependencies on providers,
and then "Provider Configuration" (formerly just "Providers") then focuses
primarily on how to write zero or more provider configurations for a
particular provider.
Because "Provider Requirements" is now presented before "Provider
Configuration" in the navigation, I've also moved some of the introductory
content about providers in general onto the "Requirements" page. The
first paragraph of that content is duplicated onto the "Configuration"
page for discoverability, but we now link to the requirements page to get
the full story.
The "Configuration Language" section was becoming rather unweildy, both
by having a lot of pages and by some of the pages being quite large in
themselves.
This is a first step towards breaking things up a little more, starting
with two changes:
- The "Configuration Language" navigation is now split into two
sub-headings "Configuration Blocks" and "Syntax".
- Some of the information about sub-blocks of the "terraform" block are
now given their own pages, because their content is quite complex
in itself.
- "Version Constraints" is now a page in its own right, rather than this
content being duplicated in slightly different forms across multiple
contexts that make use of user-specified version constraints.
We globally support a -v/-version/--version flag, which triggers the
version subcommand. The recent introduction of JSON output support meant
we started parsing the flags for the first time, but we didn't add flags
for these global version arguments.
This commit adds those flags (but doesn't check them, since they have no
effect on the version command itself). Also adds usage information for
terraform version.
* internal/initwd: fix panics with relative submodules in DirFromModule
There were two related issues here:
1. panic with any local module with submodules
1. panic with a relative directory that was above the workdir ("../")
The first panic was caused by the local installer looking up the root
module with the (nonexistant) key "root.", instead of "".
The second panic was caused by the installer trying to determine the
relative path from ".". This was fixed by detecting "." as the source
path and using the absolute path for the call to filepath.Rel.
Added test cases for both panics and updated the existing e2e tests with
the correct install paths.
