28 * Design Notes for Job Management
29 * -------------------------------
33 * pending Do nothing/check jobs
34 * pending-held Send SIGTERM to filters and backend
35 * processing Do nothing/start job
36 * stopped Send SIGKILL to filters and backend
37 * canceled Send SIGTERM to filters and backend
41 * Finalize clears the printer <-> job association, deletes the status
42 * buffer, closes all of the pipes, etc. and doesn't get run until all of
43 * the print processes are finished.
45 * UNLOADING OF JOBS (cupsdUnloadCompletedJobs)
47 * We unload the job attributes when they are not needed to reduce overall
48 * memory consumption. We don't unload jobs where job->state_value <
49 * IPP_JOB_STOPPED, job->printer != NULL, or job->access_time is recent.
51 * STARTING OF JOBS (start_job)
53 * When a job is started, a status buffer, several pipes, a security
54 * profile, and a backend process are created for the life of that job.
55 * These are shared for every file in a job. For remote print jobs, the
56 * IPP backend is provided with every file in the job and no filters are
59 * The job->printer member tracks which printer is printing a job, which
60 * can be different than the destination in job->dest for classes. The
61 * printer object also has a job pointer to track which job is being
64 * PRINTING OF JOB FILES (cupsdContinueJob)
66 * Each file in a job is filtered by 0 or more programs. After getting the
67 * list of filters needed and the total cost, the job is either passed or
68 * put back to the processing state until the current FilterLevel comes down
69 * enough to allow printing.
71 * If we can print, we build a string for the print options and run each of
72 * the filters, piping the output from one into the next.
74 * JOB STATUS UPDATES (update_job)
76 * The update_job function gets called whenever there are pending messages
77 * on the status pipe. These generally are updates to the marker-*,
78 * printer-state-message, or printer-state-reasons attributes. On EOF,
79 * finalize_job is called to clean up.
81 * FINALIZING JOBS (finalize_job)
83 * When all filters and the backend are done, we set the job state to
84 * completed (no errors), aborted (filter errors or abort-job policy),
85 * pending-held (auth required or retry-job policy), or pending
86 * (retry-current-job or stop-printer policies) as appropriate.
88 * Then we close the pipes and free the status buffers and profiles.
90 * JOB FILE COMPLETION (process_children in main.c)
92 * For multiple-file jobs, process_children (in main.c) sees that all
93 * filters have exited and calls in to print the next file if there are
94 * more files in the job, otherwise it waits for the backend to exit and
95 * update_job to do the cleanup.
