If the list was marked as computed, all values will be raw config
values. Fetch the individual keys from the config to get any known
values before validating.
The Required||Optional logic in schemaMap.Input was incorrect, causing
it to always request input. Fix the logic, and the associated tests
which were passing "just because".
helper/schema: Rename Timeout resource block to Timeouts
- Pluralize configuration argument name to better represent that there is
one block for many timeouts
- use a const for the configuration timeouts key
- update docs
Provider.TestReset resets the internal state of the Provider at the
start of a test. This also adds a MetaReset function field to
schema.Provider, which is called by TestReset and can be used to reset
any other tsated stored in the provider metadata.
This is currently used to reset the internal Context returned by
StopContext between tests, and should be implemented by a provider if
it stores a Context from a previous test.
* helper/schema: Add custom Timeout block for resources
* refactor DefaultTimeout to suuport multiple types. Load meta in Refresh from Instance State
* update vpc but it probably wont last anyway
* refactor test into table test for more cases
* rename constant keys
* refactor configdecode
* remove VPC demo
* remove comments
* remove more comments
* refactor some
* rename timeKeys to timeoutKeys
* remove note
* documentation/resources: Document the Timeout block
* document timeouts
* have a test case that covers 'hours'
* restore a System default timeout of 20 minutes, instead of 0
* restore system default timeout of 20 minutes, refactor tests, add test method to handle system default
* rename timeout key constants
* test applying timeout to state
* refactor test
* Add resource Diff test
* clarify docs
* update to use constants
This changes the type of values in Meta for InstanceState to
`interface{}`. They were `string` before.
This will allow richer structures to be persisted to this without
flatmapping them (down with flatmap!). The documentation clearly states
that only primitives/collections are allowed here.
The only thing using this was helper/schema for schema versioning.
Appropriate type checking was added to make this change safe.
The timeout work @catsby is doing will use this for a richer structure.
Fixes#12183
The fix is in flatmap for this but the entire issue is a bit more
complex. Given a schema with a computed set, if you reference it like
this:
lookup(attr[0], "field")
And "attr" contains a computed set within it, it would panic even though
"field" is available. There were a couple avenues I could've taken to
fix this:
1.) Any complex value containing any unknown value at any point is
entirely unknown.
2.) Only the specific part of the complex value is unknown.
I took route 2 so that the above works without any computed (since
"name" is not computed but something else is). This may actually have an
effect on other parts of Terraform configs, however those similar
configs would've simply crashed previously so it shouldn't break any
pre-existing configs.
Accessing an interpolated value in a map through ConfigFieldReader can
fail, because GetRaw can't access interpolated values, so check if the
value exists at all by looking in the config. If the config has a value,
assume our map's value is interpolated and proceed as such.
We also need to lookup the correct schema to properly read a field from
a nested structure.
- Maps previously always defaulted to TypeString. Now check if Elem is a
ValueType and use that if applicable
- Lists now return the schema for nested element types, defaulting to a
TypeString like maps.
This only allows maps and lists to be nested one level deep, and the
inner map or list must only contain string values.
Needed due to work done in 95d37ea, we may need to adjust
hasComputedSubKeys to propagate NewComputed in the same way that we
have added "~", however will wait for comment from @mitchellh.
This covers:
* Complex sets with computed fields in a set
* Complex lists with computed fields in a set
Adding a test to test basic lists with computed fields seemed to fail,
but possibly for an unrelated reason (the list returned as nil). The fix
to this inparticular case may be out of the scope of this specific
issue.

This fixes some edge-ish cases where a set in a config has a set or list
in it that contains computed values, but non-set or list values in the
parent do not.
This can cause "diffs didn't match during apply" errors in a scenario
such as when a set's hash is calculated off of child items (including
any sub-lists or sets, as it should be), and the hash changes between
the plan and apply diffs due to the computed values present in the
sub-list or set items. These will be marked as computed, but due to the
fact that the function was not iterating over the list or set items
properly (ie: not adding the item number to the address, so
set.0.set.foo was being yielded instead of set.0.set.0.foo), these
computed values were not being properly propagated to the parent set to
be marked as computed.

This possibly fixes other non-CloudFront related issues too.
Fixes#10125
If the elements are computed and the field is ForceNew, then we should
mark the computed count as potentially forcing a new operation.
Example, assuming `groups` forces new...
**Step 1:**
groups = ["1", "2", "3"]
At this point, the resource isn't create, so this should result in a
diff like:
CREATE resource:
groups: "" => ["1", "2", "3"]
**Step 2:**
groups = ["${computedvar}"]
The OLD behavior was:
UPDATE resource
groups.#: "3" => "computed"
This would cause a diff mismatch because if `${computedvar}` was
different then it should force new. The NEW behavior is:
DESTROY/CREATE resource:
groups.#: "3" => "computed" (forces new)
Fixes#2748
This changes the diff to only mark "forces new resource" on the fields
that actually caused the new resource, not every field that changed.
This makes diffs much more accurate.
I'd like to request a review but I'm going to defer merging until
Terraform 0.8. Changes like this are very possible to cause "diffs
didn't match" errors and I want some real world testing in a beta before
we hit prod with this.
Fixes#7715
If a bool field was computed and the raw value was not convertable to a
boolean, helper/schema would crash. The correct behavior is to try not
to read the raw value when the value is computed and to simply mark that
it is computed. This does that (and matches the behavior of the other
primitives).
Fixes#5138
If an item is optional and is removed completely from the configuration,
it should still trigger a destroy/create if the field itself was marked
as "ForceNew".
See the example in #5138.
Fixes#3309
There are two primary changes, one to how helper/schema creates diffs
and one to how Terraform compares diffs. Both require careful
understanding.
== 1. helper/schema Changes
helper/schema, given any primitive field (string, int, bool, etc.)
_used to_ create a basic diff when given a computed new value (i.e. from
an unkown interpolation). This would put in the plan that the old value
is whatever the old value was, and the new value was the actual
interpolation. For example, from #3309, the diff showed the following:
```
~ module.test.aws_eip.test-instance.0
instance: "<INSTANCE ID>" => "${element(aws_instance.test-instance.*.id, count.index)}"
```
Then, when running `apply`, the diff would be realized and you would get
a diff mismatch error because it would realize the final value is the
same and remove it from the diff.
**The change:** `helper/schema` now marks unknown primitive values with
`NewComputed` set to true. Semantically this is correct for the diff to
have this information.
== 2. Terraform Diff.Same Changes
Next, the way Terraform compares diffs needed to be updated
Specifically, the case where the diff from the plan had a NewComputed
primitive and the diff from the apply _no longer has that value_. This
is possible if the computed value ended up being the same as the old
value. This is allowed to pass through.
Together, these fix#3309.
This reverts commit c3a4cff133, reversing
changes made to 791a02e6e4.
This change requires plugin recompilation and we should hold off until a
minor release for that.
