The AWS CloudTrail resource is capable of creating CloudTrail resources,
but AWS defaults the actual logging of the trails to `false`, and
Terraform has no method to enable or monitor the status of logging.
CloudTrail trails that are inactive aren't very useful, and it's a
surprise to discover they aren't logging on creation.
Added an `enable_logging` parameter to resource_aws_cloudtrail to enable
logging. This requires some extra API calls, which are wrapped in new
internal functions.
For compatibility with AWS, the default of `enable_logging` is set to
`false`.
I promised myself that next time I jumped in this file I'd fix this up.
Now we don't have to manually index the file with comments, we can just
add descriptive names to the test cases!
* 'master' of github.com:hashicorp/terraform:
config: test covering escaped quotes syntax error
Add failing tests for JSON configuration parsing
scripts: check for the correct env vars in dist.sh
This was never intended to be valid syntax, but it worked in the old HCL
parser, and we've found a decent number of examples of it in the wild.
Fixed in https://github.com/hashicorp/hcl/pull/62 and we'll keep this
test in Terraform to cover the behavior.
This commit adds State Change support to the LBaaS resources which should
help with clean terminations.
It also adds an acceptance tests that builds out a 2-node load balance
service.
Because `aws_security_group_rule` resources are an abstraction on top of
Security Groups, they must interact with the AWS Security Group APIs in
a pattern that often results in lots of parallel requests interacting
with the same security group.
We've found that this pattern can trigger race conditions resulting in
inconsistent behavior, including:
* Rules that report as created but don't actually exist on AWS's side
* Rules that show up in AWS but don't register as being created
locally, resulting in follow up attempts to authorize the rule
failing w/ Duplicate errors
Here, we introduce a per-SG mutex that must be held by any security
group before it is allowed to interact with AWS APIs. This protects the
space between `DescribeSecurityGroup` and `Authorize*` / `Revoke*`
calls, ensuring that no other rules interact with the SG during that
span.
The included test exposes the race by applying a security group with
lots of rules, which based on the dependency graph can all be handled in
parallel. This fails most of the time without the new locking behavior.
I've omitted the mutex from `Read`, since it is only called during the
Refresh walk when no changes are being made, meaning a bunch of parallel
`DescribeSecurityGroup` API calls should be consistent in that case.
