80 * Design Notes for Job Management
81 * -------------------------------
85 * pending Do nothing/check jobs
86 * pending-held Send SIGTERM to filters and backend
87 * processing Do nothing/start job
88 * stopped Send SIGKILL to filters and backend
89 * canceled Send SIGTERM to filters and backend
93 * Finalize clears the printer <-> job association, deletes the status
94 * buffer, closes all of the pipes, etc. and doesn't get run until all of
95 * the print processes are finished.
97 * UNLOADING OF JOBS (cupsdUnloadCompletedJobs)
99 * We unload the job attributes when they are not needed to reduce overall
100 * memory consumption. We don't unload jobs where job->state_value <
101 * IPP_JOB_STOPPED, job->printer != NULL, or job->access_time is recent.
103 * STARTING OF JOBS (start_job)
105 * When a job is started, a status buffer, several pipes, a security
106 * profile, and a backend process are created for the life of that job.
107 * These are shared for every file in a job. For remote print jobs, the
108 * IPP backend is provided with every file in the job and no filters are
111 * The job->printer member tracks which printer is printing a job, which
112 * can be different than the destination in job->dest for classes. The
113 * printer object also has a job pointer to track which job is being
116 * PRINTING OF JOB FILES (cupsdContinueJob)
118 * Each file in a job is filtered by 0 or more programs. After getting the
119 * list of filters needed and the total cost, the job is either passed or
120 * put back to the processing state until the current FilterLevel comes down
121 * enough to allow printing.
123 * If we can print, we build a string for the print options and run each of
124 * the filters, piping the output from one into the next.
126 * JOB STATUS UPDATES (update_job)
128 * The update_job function gets called whenever there are pending messages
129 * on the status pipe. These generally are updates to the marker-*,
130 * printer-state-message, or printer-state-reasons attributes. On EOF,
131 * finalize_job is called to clean up.
133 * FINALIZING JOBS (finalize_job)
135 * When all filters and the backend are done, we set the job state to
136 * completed (no errors), aborted (filter errors or abort-job policy),
137 * pending-held (auth required or retry-job policy), or pending
138 * (retry-current-job or stop-printer policies) as appropriate.
140 * Then we close the pipes and free the status buffers and profiles.
142 * JOB FILE COMPLETION (process_children in main.c)
144 * For multiple-file jobs, process_children (in main.c) sees that all
145 * filters have exited and calls in to print the next file if there are
146 * more files in the job, otherwise it waits for the backend to exit and
147 * update_job to do the cleanup.
