Some error-checking was omitted.
Specifically, the cloudTrailSetLogging call in the Create function was
ignoring the return and cloudTrailGetLoggingStatus could crash on a
nil-dereference during the return. Fixed both.
Fixed some needless casting in cloudTrailGetLoggingStatus.
Clarified error message in acceptance tests.
Removed needless option from example in docs.
The default for `enable_logging`, which defines whether CloudTrail
actually logs events was originally written as defaulting to `false`,
since that's how AWS creates trails.
`true` is likely a better default for Terraform users.
Changed the default and updated the docs.
Changed the acceptance tests to verify new default behavior.
Changing the Set internals makes a lot of sense as it saves doing
conversions in multiple places and gives a central place to alter
the key when a item is computed.
This will have no side effects other then that the ordering is now
based on strings instead on integers, so the order will be different.
This will however have no effect on existing configs as these will
use the individual codes/keys and not the ordering to determine if
there is a diff or not.
Lastly (but I think also most importantly) there is a fix in this PR
that makes diffing sets extremely more performand. Before a full diff
required reading the complete Set for every single parameter/attribute
you wanted to diff, while now it only gets that specific parameter.
We have a use case where we have a Set that has 18 parameters and the
set consist of about 600 items (don't ask 😉). So when doing a diff
it would take 100% CPU of all cores and stay that way for almost an
hour before being able to complete the diff.
Debugging this we learned that for retrieving every single parameter
it made over 52.000 calls to `func (c *ResourceConfig) get(..)`. In
this function a slice is created and used only for the duration of the
call, so the time needed to create all needed slices and on the other
hand the time the garbage collector needed to clean them up again caused
the system to cripple itself. Next to that there are also some expensive
reflect calls in this function which also claimed a fair amount of CPU
time.
After this fix the number of calls needed to get a single parameter
dropped from 52.000+ to only 2! 😃
Previously we assumed the existence of some default objects that most
Opsworks users have because the Opsworks console creates them by default
when a new stack is created.
However, that meant that these tests wouldn't work correctly for anyone
who either had never used Opsworks via the UI or who had never accepted
the default of having the console create some predefined IAM objects to
use. It may also have led to some weird failures if a particular user had
customized the settings for these default objects.
Now the tests create suitable IAM roles, a policy and an instance profile
and use these when creating Opsworks stacks, avoiding any dependency
on any pre-existing objects.
This fixes#3998.
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!
