This introduces new run_process() and screen_service() functions and sets the groundwork to change how DevStack starts services. screen_service() is simply a direct call to the screen portion of the old screen_it() function and is intended to run commands that only need to run under screen, such as log file watchers. run_process() is a replacement for screen_it() (which remains until all of the services are updated). The usage is similar but requires updates to every current screen_it() call to remove everything that requires the command to be interpreted by a shell. The old run_process() and _run_process() functions are still present as old_run_process() and _old_run_process() to support the deprecated screen_it() function. These will all go away in the future once all services have been confirmed to have been changed over. There is a similar new set of stop process functions stop_process() and screen_stop_service(). The old screen_stop() will also remain for the deprecation period. As an initial test/demostration this review also includes the changes for lib/cinder to demonstrate what is required for every service. I included the scripts I used to test this; tests/fake-service.sh and tests/run-process.sh are quite rough around the edges and may bite. They should mature into productive members of the testing ecosystem someday. Change-Id: I03322bf0208353ebd267811735c66f13a516637b |
