David Meyer fe0cc3b0db config: new "rsadecrypt" interpolation function
The primary use-case is to decrypt windows passwords obtained from AWS, but this function is generic and may find other purposes too.

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 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

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

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.

2017-10-27 09:08:15 -04:00
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.

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.

to localhost.

The reason versionedPathKey didn't solve the previous test case was a

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 7416e7a6e0 update the module manifest implementation
The getter.Storage abstraction is proving entirely inadequate here, but
we can't replace it wholesale at the moment.

The Tree loader needs to know the location of the manifest before it can
start loading any modules. Since the version will have to be part of the
hashed storage key, there is no way to know what version of each module
are stored. The storageDir function will extract the StorageDir field
from the underlying FolderStorage instance for the tree to locate the
manifest.
2017-10-27 09:08:15 -04:00
James Bardin 283d88551a Add a new module storage manifest
To add registry support, a workaround in the local module storage was
added to record the subdirectory containing the module source from
within the archive file. Here we replace that temporary implementation
with the full manifest needed to record the necessary module metadata
for module loading.

In order to support versioned modules, the actual stored version needs
to be recorded. This can't be derived from the configuration, because
the configuration only contains the constraints, and at load time we need
to be able to enumerate the stored modules and all versions in order to
resolve them.

While the local storage key will be derived from the source and version,
that information is lost once it's hashed. While the entire storage
layer could be replaced to encode the needed data in the path itself,
this provides a minimal change to work with the existing storage code.

James Bardin 0962792257 surface registry errors to the user
Now that we can enforce local modules being relative or absolute paths,
we can be assured that any module source matching a registry pattern
must be found in the registry. This allows us to surface more useful
errors to the user, rather than simply stating that a source string
isn't valid.

James Bardin a359c4ee2f check the registry detector before local files
Breaking change for 0.11.

Local files were checked first to avoid the possibility of breaking a

enfore that any source iwth the pattern "namespace/identifier/provider"
must be a registry module.

2017-10-27 09:08:15 -04:00
James Bardin cb0e37a870 implement provider inheritence during loading
This implements provider inheritance during config loading, rather than
during graph evaluation. At this point it's much simpler to find the
desired configuration, and once all providers are declared, all the
inheritance code in the graph can be removed.

The inheritance is dome by simply copying the RawConfig from the parent
ProviderConfig into the module. Since this happens before any
evaluation, we record the original interpolation scope in the
ProviderConfig so that it can be properly resolved later on.

The value-conversion machinery is also needed in the main "terraform"

shim functions move here into a new package where they can be public.

Some of them remain private within the config package since they depend
on some other symbols in the config package, and they are not needed

Previously we were using fmt.Sprintf and thus forcing the stringification

containing potentially-multiple errors and possibly warnings.

Martin Atkins b91bd62747 config/configschema: Sensitive flag for attributes
We don't currently have any need for this information, but we're
propagating it out of helper/schema here pre-emptively so that once we
later have a use for it we will not need to rebuild the providers to gain
access to it.

The long-term expected use-case for this is to have Terraform Core use
static analysis techniques to trace the path of sensitive data through
interpolations so that intermediate results can be flagged as sensitive
too, but we have a lot more work to do before such a thing would actually
be possible.

Martin Atkins 0ef985cada config/configschema: Block.ImpliedType delegates to zcldec
zcldec now has its own function for computing the implied type for a spec,

our schema model here, but it produces the same results for the subset

Martin Atkins b851fa71c9 config: Make HIL-based functions available to HCL2 via a shim
Terraform has a _lot_ of functions written against HIL's function API, and
we're not ready to rewrite them all yet, so instead we shim the HIL
function API to conform to the HCL2 (really: cty) function API and thus
allow most of our existing functions to work as expected when called from
HCL2-based config files.

Not all of the functions can be fully shimmed in this way due to depending
on HIL implementation details that we can't mimic through the HCL2 API.
We don't attempt to address that yet, and instead just let them fail when
called. We will eventually address this by using first-class HCL2
functions for these few cases, thus avoiding the HIL API altogether where
we need to. (The methodology for that is already illustrated here in the
provision of jsonencode and jsondecode functions that are HCL2-native.)

Martin Atkins bbf9725134 config: Validate resource "count" for HCL2-specified resources
This early validation uses interpolation of a placeholder value to achieve
some "best effort" validation of the validity of the count attribute.
Since HCL2-specified resources can't be interpolated using the main
interpolator, here we branch and use the HCL2 API to do a
largely-equivalent (though slightly less accurate) check.

In the long run we don't really need this extra check at all, since the
validation walk does a more accurate version of the same thing. However,
we're preserving this for now in the interests of minimizing the amount
of change for the main codepath during our experiment.

Martin Atkins 71e68f06c4 config: allow tests to force using the HCL2 loader
Currently the default for tests is to use the old HCL loader, but we need
to be able to test aspects of the new loader as we work through the
experimental phase. This new function testConfigHCL2 is the same as
testConfig except that it forces the use of HCL2 even if the opt-in
comment isn't present, thus allowing us to implement tests that ensure
that the exact same file works in both the old and new cases.

Once the HCL2 loader becomes the default this function will be removed
and callers will start calling into the normal testConfig function.
2017-10-03 17:47:01 -07:00
Martin Atkins d91327eaa0 config: allow HCL2 experiment opt-in (build-time flag to enable)
Use the new HCL2 config loader when the opt-in comment #terraform:hcl2 is
present in a .tf file.

For now this is disabled for "normal" builds and enabled only if
explicitly configured via a linker flag during build. This is because it's
not yet in a good state to be released: the HCL2 loader produces RawConfig
objects that the validator and interpolator can't yet deal with, and so
using HCL2 for anything non-trivial currently causes Terraform to crash
in real use.
2017-10-03 17:47:01 -07:00
Martin Atkins b0215fcd0f config: HCL2 config loader
This loader uses the HCL2 parser and decoder to process a config file,
and then transforms the result into the same shape as would be produced
by the HCL config loader.

To avoid making changes to the existing config structures (which are
depended on across much of the codebase) we first decode into a set of
HCL2-tailored structs and then process them into the public-facing structs
that a loader is expected to return. This is a compromise to keep the
config package API broadly unchanged for now. Once we're ready to remove
the old HCL loader (which implies that we're ready to support HCL2
natively elsewhere in the codebase) we will be able to simplify this
quite considerably.

Due to some mismatches of abstraction between HCL/HIL and HCL2, some
shimming is required to get the required result.

is returned to us in an interpolation call.

in verbose mode.

James Bardin f6e89bb8c3 record the subdirectory in the FolderStorage
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.

James Bardin 1b01f18920 handle go-getter subdirs in Tree.Load
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.

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.

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
that verifies that only suitable variable types are used, and adding local
values to this whitelist was missed in the initial implementation.

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.
