Shell tab completion for all of the subcommands under
"terraform workspace", providing the appropriate kind of auto-complete for
each argument, along with completion for for any flags.
This helper is a Predictor for the "complete" package that tries to
auto-complete workspace names from the current backend, if it's
initialized and operable.
The predictors built in to the "complete" package assume that the same
type of argument is repeated indefinitely, but most Terraform commands
don't work like that, so this helper allows us to define a sequence of
predictors that apply to each argument in turn.
The CLI package has automatic support for shell autocomplete (bash and
zsh, at time of writing) for subcommands, so all we need to do here is
just opt into it.
Users can install this into their shells by running:
terraform -install-autocomplete
This adds NoZeroValues, a small SchemaValidateFunc that checks that a
defined value is not a zero value. It's useful for situations where you
want to keep someone from explicitly entering a zero value (ie:
literally "0", or an empty string) on a required field, and want to
catch it in the validation stage, versus during apply using GetOk.
Module detection currently requires calling the registry to determine
the subdirectory. Since we're not directly accessing the subdirectory
through FolderStorage, and now handling it within terraform so modules can
reference sibling paths, we need to call out to the registry every
time we load a configuration to verify the subdirectory for the module,
which is returned during the Detect.
Record the subdirectories for each module in the top-level of the
FolderStorage path for retrieval during Tree.Load. This lets us bypass
Detection altogether, modules can be loaded without redetecting.
In order to remain backward compatible with some modules, we need to
handle subdirs during Load. This means duplicating part of the go-getter
code path for subDir handling so we can resolve any subDirs and globs
internally, while keeping the entire remote directory structure within
the file storage.
Test that we can get a subdirectory from a tarball (or any other
"packed" source that we support).
The 'tar-subdir-to-parent' test highlights a regression where the
subdirectory module references a module in its parent directory. This
breaks the intended use ofr the subdirectory and the implementation in
go-getter. We need to fix this in terraform, and possible plan warnings
and deprecations for this type of source.
This new option allows importing without configuration present.
Configuration is required by default as a confirmation that the provided resource name is correct, but it can be useful to override this in tools that wrap Terraform to do more involved operations.
The getter.FileDetector was intended to be the final detector, only
converting a path to a file URL and returning a true in all cases. We
want to check for a local module before checking the registry so no
local modules that happen to match a registry module are broken.
Wrap the getter.FileDetector to check the module source's existence
before delegating the search to the registry.
updating the key will cause the FolderStorage hash to change forcing
modules to be re-fetched. This is required because any configurations
using the subDir notation will have the configuration in the wrong
directory.
Terraform was redundantly handling `//dir` notation which should be
handled by go-getter. Rather than allowing go-getter to unpack a subdir
as expected, the subdir was stripped off and accessed through the module
configuration.
This scheme will no longer works now that go-getter supports `*`
subdirectories
(e.g. `//*` would be analogous to `tar --strip-components=1`).
Even though this allows Terraform to use go-getter's native unpacking,
detection is still done separately because Detect requires a `pwd` which
is dependent on the configuration directory and not known to the
global FolderStorage.
Add a getter.Detector for detecting registry modules and looking up
the download location of the latest version. This is essentially a
temporary API until constraint solving is supported by the registry, as
then we'll have to supply the full set of known contraints to the
registry at once for resolution and we will fetch specific versions of
modules.
