From 7f97896c59d23d9dda704b19203a9ceb49b57237 Mon Sep 17 00:00:00 2001 From: Valentin Rothberg Date: Mon, 4 May 2020 14:01:39 +0200 Subject: image removal: refactor part 2 Continue the refactoring of image removal. I didn't manage to break all the following changes into smaller and easier to digest commits due to time constraints: * Return an error slice instead of a single error. Use multierror only in the client/frontend. Reflect that in the types. * Use the batch image removal in the client while preserving the more rest-idiomatic single-image removal endpoint. * Add a new handler for the single-image removal endpoint to make it share the same code as the batch endpoint. * Expose bindings for the single and batch endpoints, so we can properly test them. * Add several convenience functions for error handling to pkg/errorhandling. * Set the correct error type in libpod to set the exit code to 2 when one or more containers are using an image. * Massage the bindings tests a bit and tackle compilation errors.
