Subject [jira] [Created] (ARIA-380) Execution cancel semantics
Date Thu, 14 Sep 2017 14:54:00 GMT
Ran Ziv created ARIA-380:

             Summary: Execution cancel semantics
                 Key: ARIA-380
             Project: AriaTosca
          Issue Type: Story
            Reporter: Ran Ziv
            Priority: Trivial

At the moment, when a user cancels a workflow execution, the {{ProcessExecutor}} will kill
all subprocesses, immediately stopping any still-ongoing operations.

It might be better to provide another mode of execution cancellation, where tasks which are
already running will be let finish, but no new tasks will be executed.

One way to go about it via the CLI for example, is to have the first {{Ctrl+C}} prevent new
tasks from being added, with a second {{Ctrl+C}} tap causing any still-ongoing operations
to immediately stop, the way it is right now.
