Context:
As part of building up a Plan, Terraform needs to detect "orphaned"
resources--resources which are present in the state but not in the
config. This happens when config for those resources is removed by the
user, making it Terraform's responsibility to destroy them.
Both state and config are organized by Module into a logical tree, so
the process of finding orphans involves checking for orphaned Resources
in the current module and for orphaned Modules, which themselves will
have all their Resources marked as orphans.
Bug:
In #3114 a problem was exposed where, given a module tree that looked
like this:
```
root
|
+-- parent (empty, except for sub-modules)
|
+-- child1 (1 resource)
|
+-- child2 (1 resource)
```
If `parent` was removed, a bunch of error messages would occur during
the plan. The root cause of this was duplicate orphans appearing for the
resources in child1 and child2.
Fix:
This turned out to be a bug in orphaned module detection. When looking
for deeply nested orphaned modules, root.parent was getting added twice
as an orphaned module to the graph.
Here, we add an additional check to prevent a double add, which
addresses this scenario properly.
Fixes#3114 (the Provisioner side of it was fixed in #4877)
* Randomize app name in test
* Return error and don't panic when there is a problem
It's possible there may still be an underlying problem that caused the
error that made the cert leak in the first place - this should help us
diagnose it.
This should address the failures seen in Travis Build Run #8774. It is
likely there are others which also need addressing - they will be
addressed on a case-by-case basis as they come up.
This resource is the first which makes use of the new Riviera library
(at https://github.com/jen20/riviera), so there is some additional set
up work to add the provider to the client which gets passed among
resources.
Previous deps merge had been captured by an older version of godep,
updating godep and rerunning...
godep save $(go list ./... | grep -v /vendor/)
...yielded this diff.
New `godep` also produced a warning to pin to the major Go version
instead of the minor one, which we do here as well.
