Fixes#11038
This is a **short term fix**.
Terraform core doesn't currently handle root modules named "root" well
because the prefix `[]string{"root"}` has special meaning and Terraform
core [currently] can't disambiguate between the root module and a module
named "root" in the root module.
This PR introduces a short term fix by simply disallowing root modules
named "root". This shouldn't break any BC because since 0.8.0 this
didn't work at all in many broken ways (including crashes).
Longer term, this should be fixed by removing the special prefix at all
and having empty paths be root. I started down this path but the core
changes necessary are far too scary for a patch release. We can aim for
0.9.
Fixes#4789
This improves the validation that valid provider aliases are used.
Previously, we required that provider aliases be defined in every module
they're used. This isn't correct because the alias may be used in a
parent module and inherited.
This removes that validation and creates the validation that a provider
alias must be defined in the used module or _any parent_. This allows
inheritance to work properly.
We've always had this type of validation for aliases because we believe
its a good UX tradeoff: typo-ing an alias is really painful, so we
require declaration of alias usage. It may add a small burden to
declare, but since relatively few aliases are used, it improves the
scenario where a user fat-fingers an alias name.
This changes the key for the storage to be the _raw_ source from the
module, not the fully expanded source. Example: it'll be a relative path
instead of an absolute path.
This allows the ".terraform/modules" directory to be portable when
moving to other machines. This was a behavior that existed in <= 0.7.2
and was broken with #8398. This amends that and adds a test to verify.
Fixes the following error when cross compiling:
```
--> freebsd/amd64 error: exit status 2
Stderr: # github.com/hashicorp/terraform/config/module
config/module/inode.go:18: cannot use st.Ino (type uint32) as type uint64 in return argument
```
When copying a config module, make sure the full path for src and dst
files don't match, and also check the inode in case we resolved a
different path to the same file.
Make a note about the unsafe usage of reusing a tempDir path.

This commit fixes the failures by adjusting the file:// URL to a form that
Mercurial expects.
Only adjust the URL Scheme when parsing drive letter file paths on
Windows, don't add a file scheme prefix.
FileDetector is responsible for adding the file scheme prefix.
Absolute file paths were not correctly detected by module.Detect
when using url.Parse to parse the source URL. Wrap the detection
with urlParse to properly handle file path detections on Windows.
Fixes command test failures on Windows.
When parsing URLs on Windows, assume it is a drive letter path
if the second element is a ':' character. Format the drive letter
path as a "file:///"-path prior to parsing the URL.
Fixes test failures of the following form in command on Windows:
=== RUN TestApply_plan
--- FAIL: TestApply_plan (0.00s)
apply_test.go:379: bad: 1
module download not supported for scheme 'c'
Using url.Parse to parse an absolute file path on Windows yields
a URL type where the Path element is prefixed by a slash.
For example, parsing "file:///C:/Users/user" gives a URL type
with Path:"/C:/Users/user".
According to golang.org/issue/6027, the parsing is correct as is.
The leading slash on the Path must be eliminated before any file
operations.
This commit introduces a urlParse function which wraps the url.Parse
functionality and removes the leading slash in Path for absolute file
paths on Windows.
Fixes config/module test failures on Windows.
Specify laddr on the form host:port in the call to net.Listen as
documented for net.Dial, see godoc.org/net#Dial
