James Bardin 59089ef461 add test loading an archive with `//*` subdir
The registry uses the `//*` subdir format to unpack github archives. Add
a test to cover this pattern.

James Bardin 38569c8508 add tests for get from tar subdir
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.

James Bardin f9fb2b4c9e move local module detection ahead of the registry
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.

James Bardin d216d19f21 change the FolderStorage key
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.
2017-09-15 16:16:28 -04:00
James Bardin 6c20141c30 remove subdir handling from Tree.Load
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.

James Bardin a83ff57aea Add registry detector
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.

Martin Atkins 0a342e8dc2 config: allow local value interpolations in count
There is some additional, early validation on the "count" meta-argument

Martin Atkins 8cd0ee80e5 config: merge/append for local values
It seems that this somehow got lost in the commit/rebase shuffle and
wasn't caught by the tests that _did_ make it because they were all using
just one file.

As a result of this bug, locals would fail to work correctly in any
configuration with more than one .tf file.

Along with restoring the append/merge behavior, this also reworks some of
the tests to exercise the multi-file case as better insurance against
regressions of this sort in future.

This fixes #15969.

Martin Atkins c12d64f340 Use t.Helper() in our test helpers
Go 1.9 adds this new function which, when called, marks the caller as
being a "helper function". Helper function stack frames are then skipped
when trying to find a line of test code to blame for a test failure, so
that the code in the main test function appears in the test failure output
rather than a line within the helper function itself.

This covers many -- but probaly not all -- of our test helpers across
various packages.

Martin Atkins f70318097a config: fix provider version constraint validation
Previously we were using the "semver" library to parse version
constraints, but we switched over to go-version and encapsulated it
inside our own plugin/discovery package to reduce dependency sprawl in
the code.

This particular situation was missed when updating references to the new
path, which meant that our validation code disagreed with the rest of
the code about what is considered a valid version constraint string.
By using the correct function, we ensure that we catch early any invalid
versions.

Martin Atkins 73fc9985b2 config: add "version" argument to provider blocks, disabled
In future we will support version constraints on providers, so we're
reserving this attribute name that is currently not used by any builtin
providers.

For now using this will produce an error, since the rest of Terraform
(outside of the config parser) doesn't currently have this notion and we
don't want people to start trying to use it until its behavior is fully
defined and implemented.

It may be used by third-party providers, so this is a breaking change
worth warning about in CHANGELOG but one whose impact should be small.
Any third-party providers using this name should migrate to using a new
attribute name instead moving forward.

Martin Atkins 410b60cb7f Stop requiring multi-vars (splats) to be in array brackets
Prior to Terraform 0.7, lists in Terraform were just a shallow abstraction
on top of strings with a magic delimiter between items. Wrapping a single
string in brackets in the configuration was Terraform's prompt that it
needed to split the string on that delimiter during interpolation.

In 0.7, when first-class lists were added, this convention was preserved
by flattening lists-of-lists by one level when they were encountered in
configuration. However, there was an oversight in that change where it
did not correctly handle the case where the inner list was unknown.

In #14135 we removed some code that was flattening partially-unknown lists
into fully-unknown (untyped) values. This inadvertently exposed the missed
case from the previous paragraph, causing issues for list-wrapped splat
expressions with unknown members. While this worked fine for resources,
due to some fixup done inside helper/schema, this did not work for other
interpolation contexts such as module blocks.

Various attempts to fix this up and restore the flattening behavior
selectively were unsuccessful, due to a proliferation of assumptions all
over the core code that would be too risky to change just to fix this bug.

This change, then, takes the different approach of removing the
requirement that splats be presented inside list brackets. This
requirement didn't make much sense anymore anyway, since no other
list-returning expression had this constraint and so the rest of Terraform
was already successfully dealing with both cases.

This leaves us with two different scenarios:

- For resource arguments, existing normalization code in helper/schema
  does its own flattening that preserves compatibility with the common
  practice of using bracketed splats. This change proves this with a test
  within the "test" provider that exercises the whole Terraform core and
  helper/schema stack that assigns bracketed splats to list and set
  attributes.

- For arguments in other blocks, such as in module callsites, the
  interpolator's own flattening behavior applies to known lists,
  preserving compatibility with configurations from before
  partially-computed splats were possible, but those wishing to use
  partially-computed splats are required to drop the surrounding brackets.
  This is less concerning because this scenario was introduced only in
  0.9.5, so the scope for breakage is limited to those who adopted this
  new feature quickly after upgrading.

As of this commit, the recommendation is to stop using brackets around
splats but the old form continues to be supported for backward
compatibility. In a future _major_ version of Terraform we will probably
phase out this legacy form to improve consistency, but for now both
forms are acceptable at the expense of some (pre-existing) weird behavior
when _actual_ lists-of-lists are used.

This addresses #14521 by officially adopting the suggested workaround of
dropping the brackets around the splat. However, it doesn't yet allow
passing of a partially-unknown list between modules: that still violates
assumptions in Terraform's core, so for the moment partially-unknown lists
work only within a _single_ interpolation expression, and cannot be
passed around between expressions. Until more holistic work is done to
improve Terraform's type handling, passing a partially-unknown splat
through to a module will result in a fully-unknown list emerging on
the other side, just as was the case before #14135; this change just
addresses the fact that this was failing with an error in 0.9.5.

Martin Atkins 81b0c4b28d config: generate errors for unnamed blocks of various sources
We've been incorrectly validating (or not validating at all) the
requirement that certain blocks be followed by a name string, to prohibit
e.g. this:

    variable {}

and:

    variable = ""

Before this change we were catching this for most constructs only if
there were no _valid_ blocks of the same name in the same file. For
modules in particular, we were not catching this at all.

Now we detect this for all kinds of block (resources had a pre-existing
check, so aren't touched here) and produce a different error message
depending on which of the above incorrect forms are used.

This fixes #13575.

Martin Atkins 76dca009e0 Allow escaped interpolation-like sequences in variable defaults
The variable validator assumes that any AST node it gets from an
interpolation walk is an indicator of an interpolation. Unfortunately,
back in f223be15 we changed the interpolation walker to emit a LiteralNode
as a way to signal that the result is a literal but not identical to the
input due to escapes.

The existence of this issue suggests a bit of a design smell in that the
interpolation walker interface at first glance appears to skip over all
literals, but it actually emits them in this one situation. In the long
run we should perhaps think about whether the abstraction is right here,
but this is a shallow, tactical change that fixes #13001.

Type check the value of count so we don't panic on the conversion.

I wondered "why didn't we do this before?" There is no excuse for NOT

in 0.7, the value couldn't be anything other than a string since any
primitive can turn into a string.

Regardless, we should've always done this.

terraform: don't validate computed values in validate
This disables the computed value check for `count` during the validation
pass. This enables partial support for #3888 or #1497: as long as the
value is non-computed during the plan, complex values will work in
counts.

**Notably, this allows data source values to be present in counts!**

The "count" value can be disabled during validation safely because we
can treat it as if any field that uses `count.index` is computed for
validation. We then validate a single instance (as if `count = 1`) just
to make sure all required fields are set.

config/module: disallow root modules named "root"
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.

config: smarter provider alias usage validation
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.

config: Merge respects Terraform blocks, provider aliases, and more
Fixes #10715

`config.Merge` was not updated to support a number of new features. This
updates the codepath to merge various fields, including the `terraform`
block which was the issue in #10715.

The `Merge` API is called when an `_override` file is present to _merge_
configurations. Normally configurations are _appended_. Only an override
file triggers a _merge_.

I started working on a generic library to do this automatically awhile
back but never finished it. This might motivate me to do so. In the
interest of getting a fix out though, we'll continue the manual
approach.

compatibility and how people can fix this going forward.

Martin Atkins 399542a168 core: allow outputs to have descriptions (#9722)
We allow variables to have descriptions specified, as additional context
for a module user as to what should be provided for a given variable.

We previously lacked a similar mechanism for outputs. Since they too are
part of a module's public interface, it makes sense to be able to add
descriptions for these for symmetry's sake.

This change makes a "description" attribute valid within an "output"
configuration block and stores it within the configuration data structure,
but doesn't yet do anything further with it. For now this is useful only
for third-party tools that might parse a module's config to generate
user documentation; later we could expose the descriptions as part of
the "apply" output, but that is left for a separate change.

config: maintain slice index accounting for computed keys
Fixes #10075
Fixes #10013

When interpolating, we were only maintaining the last known slice index.
If you had sibling slices then you could lose your slice index when
exiting the slice. The resulting behavior was that no some runs the
computed key would be: "slice.0.attr" and on others would be
"slice.attr", the latter being incorrect.

We now maintain a list of slice indexes so that as we unnest, we
properly restore the old value.

Surprisingly unrelated to the graph but the shadow graph caught this
which is great. :)

allow directories with no Terraform configurations.
For import, we allow directories with no Terraform configurations so
this option is set to true.

cleaned up a lot more but I left it mostly as-is to fix the bug.

config/module: use the raw source as part of the key
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.
