Previous to this commit, the Chainable class which is responsible for
iterating on the sequence of events in the intro Terraform animation,
was using setTimeout and thus could result in very messed up race
conditions when triggering physics changes.
This commit attaches the .wait timers to the Engine.render loop which
should enable everything to stay in sync.
Now that readMap filters out '#' fields, when maps are nested in sets,
we exposed a related bug where a set was iterating over nested maps and
expected the '#' key to be present in those nested maps.
By skipping _all_ count fields when iterating over set keys, all is
right with the world again.
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.
