GDB has evolved in the last several years to provide a Python API. This series of articles will look at how a user can program GDB with the API and will also take an in-depth look at several features of that API. But, before we begin, a small history lesson is needed and a look at just why an API was needed.
I am pleased to announce the general availability of numerous Red Hat curated collections of the latest, stable application development tools, languages, compilers, databases, and more. Created for Red Hat Enterprise Linux, developers can access these via the following open source offerings:
Red Hat Software Collections
Red Hat Developer Toolset
New RHEL Compilers: Clang/LLVM, Go, and Rust
Components delivered as Linux Containers can also be used on Red Hat OpenShift Container Platform.

In an environment where OpenStack instances are automatically subscribed to Satellite, it is important that Satellite is notified of terminated instances so that is can safely delete its host record. Not doing so will:
Exhaust the available subscriptions, leading to unsubscribed hosts not being able to apply updates and security errata.
In the event that an emergency security errata needs to be deployed across the organization, Satellite administrators would be unable to determine if a host was either off or terminated, leading to uncertainty with their security posture.
In smaller environments, where one team is responsible for both OSP and Satellite, it’s possible to have one system administrator do this by using their administrator level access across both systems to determine which host records can be safely deleted in Satellite when the corresponding instance no longer exists.
