If the shell spawns a subprocess which doesn't close the output file
descriptors, the exec.Cmd will block on Wait() (see
golang.org/issue/18874). Use an os.Pipe to provide the command with a
real file descriptor so the exec package doesn't need to do the copy
manually. This in turn may block our own reading goroutine, but we can
select on that and leave it for cleanup later.
If an `aws_volume_attachment` is identical to one that already exists in
the API, don't attempt to re-create it (which fails), simply act as
though the creation command had already been run and continue.
This allows Terraform to cleanly recover from a situation where a volume
attachment action hangs indefinitely, possibly due to a bad instance
state, requiring manual intervention such as an instance reboot. In such
a situation, Terraform believes the attachment has failed, when in fact
it succeeded after the timeout had expired. On the subsequent retry run,
attempting to re-create the attachment will fail outright, due to the
AttachVolume API call being non-idempotent. This patch implements the
idempotency client-side by matching the (name, vID, iID) tuple.
Note that volume attachments are not assigned an ID by the API.

The error message for a required parameter being missing has a wrong parameter baked into it. Therefore, when the error message tried to fire, it was throwing a panic. Added a test to make sure that we know the condition still fires and with a correct message
Fixes: #11587
Adds a small note to the `initial_lifecycle_hook` to note that this will
only work when creating a new Autoscaling group. For everything else,
you need to use the `aws_autoscaling_lifecycle_hook` resource

When a user passes the wrong argument to a route53_record import, they
got a crash. This was because we expected the ID to parse correctly. The
crash looked like this:
```
% terraform import aws_route53_record.import1 mike.westredd.com
aws_route53_record.import1: Importing from ID "mike.westredd.com"...
aws_route53_record.import1: Import complete!
Imported aws_route53_record (ID: mike.westredd.com)
aws_route53_record.import1: Refreshing state... (ID: mike.westredd.com)
Error importing: 1 error(s) occurred:
* aws_route53_record.import1: unexpected EOF
panic: runtime error: index out of range
```
Rather than throwing a panic to the user, we should present them with a more useful message that tells them what the error is:
```
% terraform import aws_route53_record.import mike.westredd.com
aws_route53_record.import: Importing from ID "mike.westredd.com"...
aws_route53_record.import: Import complete!

```
At least they can work out what the problem is in this case
Cloud SQL Gen 2 instances come with a default 'root'@'%' user on
creation. This change automatically deletes that user after creation. A
Terraform user must use the google_sql_user to create a user with
appropriate host and password.
Terraform can't tell the difference between an empty output and an
undefined output. This is often confusing for folks using interpolation.
As much as it would be great to fix upstream, changing this error
message to be a bit more helpful is a good stop-gap to avoid
frustration.
The `aws_availability_zones` data source test was panicking. This fixes both tests

* Added Step Function Activity & Step Function State Machine
* Added SFN State Machine documentation
* Added aws_sfn_activity & documentation
* Allowed import of sfn resources
* Added more checks on tests, fixed documentation
* Handled the update case of a SFN function (might be already deleting)
* Removed the State Machine import test file
* Fixed the eventual consistency of the read after delete for SFN functions
This adds a Meta field (similar to InstanceState.Meta) to InstanceDiff.
This allows providers to store arbitrary k/v data as part of a diff and
have it persist through to the Apply. This will be used by helper/schema
for timeout storage being done by @catsby.
The type here is `map[string]interface{}`. A couple notes:
* **Not using `string`**: The Meta field of InstanceState is a string
value. We've learned that forcing things to strings is bad. Let's
just allow types.
* **Primitives only**: Even though it is type `interface{}`, it must
be able to cleanly pass the go-plugin RPC barrier as well as be
encoded to a file as Gob. Given these constraints, the value must
only comprise of primitive types and collections. No structs,
functions, channels, etc.
The API asks you to send lower case values, but returns uppercase ones.
Here we lowercase the returned API values.
There is no migration here because the field in question is nested in a
set, so the hash will change regardless. Anyone using this feature now
has it broken anyway.
