This adds NoZeroValues, a small SchemaValidateFunc that checks that a
defined value is not a zero value. It's useful for situations where you
want to keep someone from explicitly entering a zero value (ie:
literally "0", or an empty string) on a required field, and want to
catch it in the validation stage, versus during apply using GetOk.
Add an ImportStateIdFunc field to the ImportState testing functionality.
This will allow for more powerful generation of complex import state IDs
that can't be accomplished by ImportStateId or ImportStateIdPrefix
themselves.
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.
Add the ValidateListUniqueStrings function, which is a ValidateFunc that
ensures a list has no duplicate items in it. It's useful for when a list
is needed over a set because order matters, yet the items still need to
be unique.
This adds a ValidateRegexp validation helper to check to see if a field
has a valid regular expression.
Includes test for good regexp, and test for bad regexp.
Equality of schema.Sets gets tricky when dealing with nested sets -
Set.Equal only superficially compares the underlying maps and hence any
sets nested under the root sets cause issues.
This adds a simple method, HashEqual, that does a top-level hash
comparison, helping to work around this without any complex re-invention
of things like reflect.DeepEqual.
Of course, in order to make effective use of this function, the user
needs to make sure they are properly hashing their nested sets, however
this is trivial with things like HashResource.
Adds `GetOkRaw` as a schema function. This should only be used to verify
boolean attributes are either set or not set, regardless of their zero
value for their type. There are a few small use cases outside of the boolean
type where this will be helpful as well.
Overall, this shouldn't detract from the zero-value checks that `GetOK()`
currently has, and should only be used when absolutely needed. However,
there are enough use-cases for this addition without checking for the
zero-value of the type, that this is needed.
Primary use case is for a boolean attribute that is `Optional` and `Computed`,
without a default value. There's currently no way to verify that the boolean
attribute was explicitly set to the zero-value literal with the current
`GetOk()` function. This new function allows for that check, keeping the
`Computed` check for the returned `exists` boolean.

The field reader code path is extremely inefficient, but refactoring
it all is much to invasive a change at the moment.
Have DiffFieldReader internally cache results for ReadField.
Provider import tests previously didn't have to supply a config, but
terraform now requires the provider to be declared for discovery.
testProviderConfig returns a stub config with provider blocks based
on the TestCase Providers. This allows basic import tests in providers
to remain unchanged.
The Close methods on shadow.Values require pointer receivers because
they contain a sync.Mutex, but that value was being copied through
Value.Interface by the closeWalker. Because reflectwalk passes the
struct fields to the StructField method as they are defined in the
struct, and they may have been read as a value, we can't immediately
call Interface() to check the method set without possibly copying the
internal mutex values. Use the Implements method to first check if we
need to call Interface, and if it's not, then we can check if the value
is addressable.
Because of this use of reflection, we can't vet for the copying of these
locks. The minimal amount of code in the Close method left us only with
a race detected within the mutex itself, which leads to a stacktrace
pointing to the runtime rather than our code.
It turns out that `d.GetOk` also returns `false` when the user _did_ actually supply a value for it in the config, but the value itself needs to be evaluated before it can be used.
So instead of passing a `ResourceData` we now pass a `ResourceConfig`
which makes much more sense for doing the validation anyway.
The timestamp prefix added in #8249 was removed in #10152 to ensure that
returned IDs really are properly ordered. However, this meant that IDs were no
longer ordered over multiple invocations of terraform, which was the main
motivation for adding the timestamp in the first place. This commit does a
hybrid: timestamp-plus-incrementing-counter instead of just incrementing counter
or timestamp-plus-random.
Rather than providing an already-resolved map of plugins to core, we now
provide a "provider resolver" which knows how to resolve a set of provider
dependencies, to be determined later, and produce that map.
This requires the context to be instantiated in a different way, so this
very noisy diff is a mostly-mechanical update of all of the existing
places where contexts get created for testing, using some adapted versions
of the pre-existing utilities for passing in mock providers.
Previously having a config was mutually exclusive with running an import,
but we need to provide a config so that the provider is declared, or else
we can't actually complete the import in the future world where providers
are installed dynamically based on their declarations.
* provider/aws: Add Sweeper setup, Sweepers for DB Option Group, Key Pair
* provider/google: Add sweeper for any leaked databases
* more recursion and added LC sweeper, to test out the Dependency path
* implement a dependency example
* implement sweep-run flag to filter runs
* stub a test for TestMain
* test for multiple -sweep-run list
GH-14784 allowed nested structures to be validate, rather than relying
on the raw value. However this still returns the same validation error
if the structures contain a computed value, since Get will return the
raw string in that case.
This simply skips the validation in the IsComputed case, since there's
nothing that can be checked.
When interpreting a nested object, we were validating against the "raw"
value, and not the interpolated value, causing incorrect errors.
This affects structures such as:
```tf
tags = "${list(map("foo", "bar"))}"
```
Prior to this, a complaint about "expected object, got string" since the
raw value is obviously a string, when the interpolated value is the
correct shape.
The tests did pass, but that was because they only tested part of the changes. By using the `schema.TestResourceDataRaw` function the schema and config are better tested and so they pointed out a problem with the schema of the Chef provisioner.
The `Elem` fields did not have a `*schema.Schema` but a `schema.Schema` and in an `Elem` schema only the `Type` field may (and must) be set. Any other fields like `Optional` are not allowed here.
Next to fixing that problem I also did a little refactoring and cleaning up. Mainly making the `ProvisionerS` private (`provisioner`) and removing the deprecated fields.
1. Migrate `chef` provisioner to `schema.Provisioner`:
* `chef.Provisioner` structure was renamed to `ProvisionerS`and now it's decoded from `schema.ResourceData` instead of `terraform.ResourceConfig` using simple copy-paste-based solution;
* Added simple schema without any validation yet.
2. Support `ValidateFunc` validate function : implemented in `file` and `chef` provisioners.
Besides the support for DO certificates themselves, this commit also
includes:
1) A new `RandTLSCert` function that generates a valid, self-signed TLS
certificate to be used in the test
2) A fix for the PEM encoding of the private key generated in
`RandSSHKeyPair`: the PEM was always empty
If a schema.TypeList had a Schema with ForceNew, and if that list was
NewComputed, the diff would not have RequiresNew set. This causes apply
to fail when the diffs didn't match because of the change to
RequiresNew.
Set the RequiresNew field on the list's ResourceAttrDiff based on the
Schema value.
stringer has changed the boilerplate it generates in a recent version.
We'd previously updated to the new format but accientally rolled back
to the old while merging a long-running feature branch.
This restores us back to the new format again.
