* Design Notes for Job Management
* -------------------------------
*
* STATE CHANGES
*
* pending Do nothing/check jobs
* pending-held Send SIGTERM to filters and backend
* processing Do nothing/start job
* stopped Send SIGKILL to filters and backend
* canceled Send SIGTERM to filters and backend
* aborted Finalize
* completed Finalize
*
* Finalize clears the printer <-> job association, deletes the status
* buffer, closes all of the pipes, etc. and doesn't get run until all of
* the print processes are finished.
*
* UNLOADING OF JOBS (cupsdUnloadCompletedJobs)
*
* We unload the job attributes when they are not needed to reduce overall
* memory consumption. We don't unload jobs where job->state_value <
* IPP_JOB_STOPPED, job->printer != NULL, or job->access_time is recent.
*
* STARTING OF JOBS (start_job)
*
* When a job is started, a status buffer, several pipes, a security
* profile, and a backend process are created for the life of that job.
* These are shared for every file in a job. For remote print jobs, the
* IPP backend is provided with every file in the job and no filters are
* run.
*
* The job->printer member tracks which printer is printing a job, which
* can be different than the destination in job->dest for classes. The
* printer object also has a job pointer to track which job is being
* printed.
*
* PRINTING OF JOB FILES (cupsdContinueJob)
*
* Each file in a job is filtered by 0 or more programs. After getting the
* list of filters needed and the total cost, the job is either passed or
* put back to the processing state until the current FilterLevel comes down
* enough to allow printing.
*
* If we can print, we build a string for the print options and run each of
* the filters, piping the output from one into the next.
*
* JOB STATUS UPDATES (update_job)
*
* The update_job function gets called whenever there are pending messages
* on the status pipe. These generally are updates to the marker-*,
* printer-state-message, or printer-state-reasons attributes. On EOF,
* finalize_job is called to clean up.
*
* FINALIZING JOBS (finalize_job)
*
* When all filters and the backend are done, we set the job state to
* completed (no errors), aborted (filter errors or abort-job policy),
* pending-held (auth required or retry-job policy), or pending
* (retry-current-job or stop-printer policies) as appropriate.
*
* Then we close the pipes and free the status buffers and profiles.
*
* JOB FILE COMPLETION (process_children in main.c)
*
* For multiple-file jobs, process_children (in main.c) sees that all
* filters have exited and calls in to print the next file if there are
* more files in the job, otherwise it waits for the backend to exit and
* update_job to do the cleanup.
