The `SourceDestCheck` attribute can only be changed via
`ModifyInstance`, so the AWS instance resource's `Create` function calls
out to `Update` before it returns to take care of applying
`source_dest_check` properly.
The `Update` function originally guarded against unnecessary API calls
with `GetOk`, which worked fine until #993 when we changed the `GetOk`
semantics to no longer distinguish between "configured and zero-value"
and "not configured".
I attempted in #1003 to fix this by switching to `HasChange` for the
guard, but this does not work in the `Create` case.
I played around with a few different ideas, none of which worked:
(a) Setting `Default: true` on `source_dest_check' has no effect
(b) Setting `Computed: true` on `source_dest_check' and adding a `d.Set`
call in the `Read` function (which will initially set the value to `true`
after instance creation). I really thought I could get this to work,
but it results in the following:
```go
d.Get('source_dest_check') // true
d.HasChange('source_dest_check') // false
d.GetChange('source_dest_check') // old: false, new: false
```
I couldn't figure out a way of coherently dealing with that result, so I
ended up throwing up my hands and giving up on the guard altogether.
We'll call `ModifyInstance` more than we have to, but this at least
yields expected behavior for both Creates and Updates.

This commit updates the Route 53 Zone resource to use AWS Labs aws-sdk-go
library instead of mitchellh/goamz.
- hard code us-east-1 for Route53 region, since it's a global endpoint
- add some units test for CleanZoneID
Unfortunately, the acceptance tests here were improperly passing, and
allowing Subnet updates on ELBs is not as straightfoward as simply
removing `ForceNew`.
Subnets on ELBs need to be managed by two explicit API calls:
* `AttachLoadBalancerToSubnets` - http://bit.ly/elbattachsubnet
* `DetachLoadBalanceFromSubnets` - http://bit.ly/elbdetachsubnet
We'll need to circle back and use these APIs to explicitly add support.
This fixes the failure of `TestAccAWSELB_AddSubnet` by removing the
test.
This reverts commit 61e91017be, reversing
changes made to 49b3afe452.
Was relying on old behavior of GetOk and therefore never properly seeing
a change from true -> false.
This fixes the acceptance test failure of
`TestAccAWSInstance_sourceDestCheck`.
The Mailgun provider was relying on an old behavior of
`ResourceData.Set` that would allow nested access to
maps. We now just build up our own maps like sane people.
AWS provides a single `BlockDeviceMapping` to manage three different
kinds of block devices:
(a) The root volume
(b) Ephemeral storage
(c) Additional EBS volumes
Each of these types has slightly different semantics [1].
(a) The root volume is defined by the AMI; it can only be customized
with `volume_size`, `volume_type`, and `delete_on_termination`.
(b) Ephemeral storage is made available based on instance type [2]. It's
attached automatically if _no_ block device mappings are specified, and
must otherwise be defined with block device mapping entries that contain
only DeviceName set to a device like "/dev/sdX" and VirtualName set to
"ephemeralN".
(c) Additional EBS volumes are controlled by mappings that omit
`virtual_name` and can specify `volume_size`, `volume_type`,
`delete_on_termination`, `snapshot_id`, and `encryption`.
After deciding to ignore root block devices to fix#859, we had users
with configurations that were attempting to manage the root block device chime
in on #913.
Terraform does not have the primitives to be able to properly handle a
single collection of resources that is partially managed and partially
computed, so our strategy here is to break out logical sub-resources for
Terraform and hide the BlockDeviceMapping inside the provider
implementation.
Now (a) is supported by the `root_block_device` sub-resource, and (b)
and (c) are still both merged together under `block_device`, though I
have yet to see ephemeral block devices working properly.
Looking into possibly separating out `ephemeral_block_device` and
`ebs_block_device` sub-resources as well, which seem like the logical
next step. We'll wait until the next big release for this, though, since
it will break backcompat.

Right now we yield a perpetual diff on ASGs because we're not reading
termination policies back out in the provider.
This depends on https://github.com/mitchellh/goamz/pull/218 and fixes
it.
An `InstanceDiff` will include `ResourceAttrDiff` entries for the
"length" / `#` field of maps. This makes sense, since for something like
`terraform plan` it's useful to see when counts are changing.
The `DiffFieldReader` was not taking these entries into account when
reading maps out, and was therefore incorrectly returning maps that
included an extra `'#'` field, which was causing all sorts of havoc
for providers (extra tags on AWS instances, broken google compute
instance launch, possibly others).
* fixes#914 - extra tags on AWS instances
* fixes#883 - general core issue sprouted from #757
* removes the hack+TODO from #757
This resource allows an existing Route Table to be assigned as the
"main" Route Table of a VPC. This means that the Route Table will be
used for any subnets within the VPC without an explicit Route Table
assigned [1].
This is particularly useful in getting an Internet Gateway in place as
the default for a VPC, since the automatically created Main Route Table
does not have one [2].
Note that this resource is an abstraction over an association and does not
map directly to a CRUD-able object in AWS. In order to retain a coherent
"Delete" operation for this resource, we remember the ID of the AWS-created
Route Table and reset the VPC's main Route Table to it when this
resource is deleted.

If map_public_ip_on_launch was not specified, AWS picks a default of
"0", which is different than the "" in the state file, triggerinng an
update each time. Mark that parameter as Computed, avoiding the update.
This is necessary to support creating parameter groups with parameters
that require a reboot, since the RDS API will return an error when
attempting to set those parameters with ApplyMethod "immediate".
If a subnet exists in the state file and a refresh is performed, the
read function for subnets would return an error. Now it updates the
state to indicate that the subnet no longer exists, so Terraform can
plan to recreate it.
