disabling profiling around python-libfaketime example
# An example to disable profiling when faking time with python-libfaketime.
# Call this once from setup_package or a similar hook at the start of the test run.
def disable_profiling_around_libfaketime(nose_config):
libfaketime's interception of time system calls will break profilers.
If we detect that we're running under a profiler, we set up libfaketime callbacks to
temporarily disable profiling when we're faking the time.

disable ASG scaling processes during CodeDeploy deploys
Suspend an auto scaling group's scaling processes that can interfere with CodeDeploy deploys.
It assumes a single ASG per deployment group.
To use this:
* create a lambda function with this code, then hook up it up to an SNS topic that receives all deployment events (but not host events).
* attach that topic as a trigger in your deployment groups.
Unlike AWS's in-appspec approach, this supports arbitrary deploy concurrency.
