Pierre-Alain TORET 128f4d19e1 config: Allow build on DragonFlyBSD
DragonFlyBSD is not officially supported, but allowing it to work is straightforward at the moment so we'll allow it for now.

James Bardin cf4995d8a7 use the full module name with host for errors
The module related logs and errors should reference the full module name
including the source host.

Martin Atkins 87e1fb4d66 config: a nicer error message for invalid provider constraints
Previously our error message here was confusing and redundant:

    Error starting operation: provider.null: invalid version constraint "not valid": Malformed constraint: not valid

Instead, we'll generate a full HCL2 diagnostic here, which results in
something (subjectively) nicer:

    Error: Invalid provider version constraint

    The value "@ 1.0.0" given for provider.null is not a valid version
    constraint.

At the moment this message is an outlier in that the other validation
errors are all still just plain Go errors, but over time we'll want to
adjust all of these to be full diagnostics so that we can embed source
range information in them to help the user find the offending
configuration.

There should be no warning when accessing a resource's count value
directly in an output.

Martin Atkins cc5e480378 config: detect and warn about access to "counted" attributes
A common pattern is to conditionally assign to "count"
in a resource in order to decide dynamically whether it
should be created. In that situation it's necessary to
refer to attributes of the resource using the splat
syntax, but historically we didn't show errors in output
expressions and so people "got away with" incorrect usage
in that context.

The intent of this warning is to catch
potentially-problematic usage of attributes on such
resources even if the count happens to be currently
set dynamically to 1, which would not generate the
error. Then the user can quickly locate and fix the
incorrect usage regardless of the current value.

Martin Atkins ba0514106a return tfdiags.Diagnostics from validation methods
Validation is the best time to return detailed diagnostics
to the user since we're much more likely to have source
location information, etc than we are in later operations.

This change doesn't actually add any detail to the messages
yet, but it changes the interface so that we can gradually
introduce more detailed diagnostics over time.

While here there are some minor adjustments to some of the
messages to improve their consistency with terminology we
use elsewhere.

James Bardin 8091bd627d move Svchost method to regsrc.Module
The level of abstraction that needs the "svchost" is the Module, not the
FriendlyHost. Us the new method in the module package for registry
interaction.

James Bardin bd576d780a failing test for module not found error
The "not found" error should use the raw string directly from the config
source, but the existing method was adding the default registry if there
was no host indicated.

James Bardin 8619f566bb validate providers passed to a module exist
This validation was lost in the migration of inheritance back to core.
Make sure a module configuraton doesn't specifiy a provider that doesn't
exist.

James Bardin b79adeae02 save resolved providers for resources to state
Use the ResourceState.Provider field to store the full name of the
provider used during apply. This field is only used when a resource is
removed from the config, and will allow that resource to be removed by
the exact same provider with which it was created.

Modify the locations which might accept the alue of the
ResourceState.Provider field to detect that the name is resolved.

James Bardin b15258dfec remove provider inheritance from Tree.Load
Now that resources can be connected to providers with different paths in
the core graph, handling the inheritance in config makes less sense.

Removing this to make room for core to walk the Tree and connect
resources directly to the proper provider instance.

Change "Downloading" to 'Initializing" to match the provider loading
dialog.

List each module being loaded.

If a regisry module is being downloaded, list the registry host, and the

Show the source string from the config that is being fetched, rather
than the go-getter url. The full source can be found in the logs for

James Bardin 838ffafc18 stop adding implicit provider configs
Now that providers in the graph can adopt resources without an explicit
provider, there's no need to add the implicit configs to the module.Tree
when loading.

Martin Atkins 505683dcd3 config/module: produce explicit error for non-registry hosts
If registry API discovery fails for a particular host then it's better to
generate an explicit error message for that early -- so we can tell the
user exactly what happened -- rather than assuming a default path and
then failing downstream when we get a 404 from that request.

Martin Atkins 288f7c00e4 config/module: allow registry download sources to be relative paths
It's not always easy or convenient for a web application to determine its
own absolute URL to return, so here we pragmatically allow the download
source string from a registry to be a path relative to the download
endpoint.

Since X-Terraform-Get is a go-getter string, not all valid values are
valid URLs and so we sniff for certain relative-path-looking prefixes
in order to decide whether to apply the relative lookup transform.

James Bardin eef2129f1a Storage.GetModule
Add GetModule for the cli to initialize from a regisry module source.

Storage.GetModule fetches a module using the same detection and
discovery as used by the normal module loading. The final copy is still
done by module.GetCopy to remove vcs files.

get rid of stutter and use module.Storage
2017-10-27 13:11:21 -04:00
James Bardin f2a7b94692 use the new ModuleStorage in the command package
Update the command package to use the new module storage. Move the old
command output strings into the module storage itself. This could be
moved back later either by using ui callbacks, or designing a module
storage interface once we know what the final requirements will look
like.
2017-10-27 12:58:24 -04:00
James Bardin 36eb40a432 export ModuleStorage and use it for Tree.Load
Exporting ModuleStorage allows us to explicitly pass in the storgae
location rather than extracting it out of the getter.Storage interface,
set a UI for communiating actions back to the user, and accepting a
services Disco for discovery.

James Bardin 1756b3d09f ProviderConfig needs an Inherited flag
If a provider configuration is inherited from another module, any
interpolations in that config won't have variables declared locally. Let
the config only be validated in it's original location.

James Bardin 0afd4a9097 Lookup registry module versions during Tree.Load.
Registry modules can't be handled directly by the getter.Storage
implementation, which doesn't know how to handle versions. First see if
we have a matching module stored that satisfies our constraints. If
not, and we're getting or updating, we can look it up in the registry.

This essentially takes the place of a "registry detector" for go-getter,
but required the intermediate step of resolving the version dependency.

This also starts breaking up the huge Tree.Load method into more
manageable parts. It was sorely needed, as indicated by the difficulty
encountered in this refactor. There's still a lot that can be done to
improve this, but at least there are now a few easier to read methods
when we come back to it.
2017-10-27 09:08:15 -04:00
James Bardin 0d10564a74 remove the registryDetector
The detection of registry modules will have to happen in mutliple
phases. The go-getter interface requires that the detector return the
final URL, while we won't know that until we verify which version we
need. This leaves the regisry sources broken, to be re-integrated in a
following commit.
2017-10-27 09:08:15 -04:00
James Bardin ee36cf28e0 a series of test commits
wire up HTTP so we can test the mock discovery service

test lookupModuleVersions

Add a versions endpoint to the mock registry, and use that to verify the
lookupModuleVersions behavior.

lookupModuleVersions takes a Disco as the argument so a custom Transport
can be injected, and uses that transport for its own client if it set.

test looking up modules with default registry

Add registry.terrform.io to the hostname that the mock registry resolves
to localhost.

ACC test looking up module versions

Lookup a basic module for the available version in the default registry.

James Bardin ae2903b810 missing current module source in versionedPathKey
The reason versionedPathKey didn't solve the previous test case was a
missing source string for the current module.
2017-10-27 09:08:15 -04:00
James Bardin c01dfa7757 failing test for changing intermediate modules
This test highlights how changing an intermediate source path prevents
reloading of submodules. While this is somewhat of an edge case now, it
becomes quite common in the cacse where module versions are updated.
2017-10-27 09:08:15 -04:00
James Bardin a5c86aeff6 Use the new regsrc and response packages
Adds basic detector for registry module source strings. While this isn't
a thorough validation, this will eliminate anything that is definitely
not a registry module, and split out our host and module id strings.

lookupModuleVersions interrogates the registry for the available
versions of a particular module and the tree of dependencies.
2017-10-27 09:08:15 -04:00
James Bardin 0bc279557e add more metadata to the Tree and the storage path
Submodules were located by using their module path as the storage key.
Now that modules may have versions, a submodule needs to know how to
locate the corect source depending on the versions of its ancestors in
the tree.

Add a version field to each Tree, and a pointer back to the parent Tree
to step back through the ancestors. The new versionedPathKey method uses
this information to build a unique key for each module, dependent on the
ancestor versions.

Not only do stored modules need to know their version if it exists, but
any relative source needs to know all the ancestor versions in order to
resolve correctly.
2017-10-27 09:08:15 -04:00
James Bardin 1f44fd8eb2 move getStorage to moduleStorage too
