Without using absolute paths any module info is lost in the output. And the attributes were randomly ordered and so changed between different executions of the command.
`Any()` allows any single passing validation of multiple `SchemaValidateFunc` to pass validation to cover cases where a standard validation function does not cover the functionality or to make error messaging simpler.
Example provider usage:
```go
ValidateFunc: validation.Any(
validation.IntAtLeast(42),
validation.IntAtMost(5),
),
```
When HCL encounters an error during expression evaluation, it annotates
its diagnostics with information about the expression that was being
evaluated and the EvalContext it was evaluated in.
This gives us enough information to show helpful hints to the user about
the final values of any reference expressions that are present in the
expression, which is very useful extra context for expressions that get
evaluated multiple times, such as:
- Any expression in a block with "count" or "for_each" set
- The sub-expressions within a "for" expression
HCL diagnostics relating to expression evaluation include these, so this
is really just to pass that information through our Terraform-specific
diagnostics interface.
Since protoc is not go-gettable, and most development tasks in Terraform
won't involve recompiling protoc files anyway, we'll use a separate
mechanism for these.
This way "go generate" only depends on things we can "go get" in the
"make tools" target.
In a later commit we should also in some way specify a particular version
of protoc to use so that we don't get "flapping" regenerations as
developers work with different versions, but the priority here is just to
make "make generate" minimally usable again to restore the dev workflow
documented in the README.
This also includes some updates that resulted from running "make generate"
and "make protobuf" after those Makefile changes were in place.
Change ValidateProviderConfig to PrepareProviderConfig.
Providers have a concept of "required fields with defaults" that that
was handled previously by helper/schema doing input and validation.
Because Input and Validation is mostly now handled by core, the provider
had no way of setting default values for missing required attributes.
To achieve the same behavior with new providers, there will be a
PrepareProviderConfig, which allow for manual validation, as well as
alteration of the config. The provider is free to set whatever
attributes necessary to create a valid config and return it to the
caller. If a new config is returned, it will be used instead of the
original in the subsequent Configure call, however core may still add
missing required values during an optional Input phase.
This contains a fix for a panic in Value.HasElement when used on a set
value whose element type is an object or tuple.
A few other minor dependency upgrades came long for the ride.
ProposedNewObject intentionally replaces a null prior with an unknown
prior in order to easily fill in unknown values where they "show through"
under values not set explicitly in config, but it was failing to handle
that situation when dealing with nested blocks that are backed by sets.
Due to the unusual way v0.12 was developed (because of the large amount
of cross-cutting refactoring) we have not built out an incremental
changelog along the way as we normally would.
This is an initial catchup of the changelog for the current tree at the
time of writing, with the intent that we will maintain this in the usual
way moving forward as we head towards the v0.12-alpha1 release.
`All()` combines the outputs of multiple `SchemaValidateFunc`, to reduce the usage of custom validation functions that implement standard validation functions.
Example provider usage:
```go
ValidateFunc: validation.All(
StringLenBetween(5, 42),
StringMatch(regexp.MustCompile(`[a-zA-Z0-9]+`), "value must be alphanumeric"),
),
```
`IntInSlice()` is the `int` equivalent of `StringInSlice()`
Example provider usage:
```go
ValidateFunc: validation.IntInSlice([]int{30, 60, 120})
```
Output from unit testing:
```
$ make test TEST=./helper/validation
==> Checking that code complies with gofmt requirements...
go generate ./...

```
The helper/resource unit tests will panic, because they were using the
legacy terraform.MockResourceProvider, which doesn't have the same
internals required by the new GRPC shims.
Fail these tests for now, and a new test provider will need to be made
out of a schema.Provider instance.
