78 * Design Notes for Job Management
79 * -------------------------------
83 * pending Do nothing/check jobs
84 * pending-held Send SIGTERM to filters and backend
85 * processing Do nothing/start job
86 * stopped Send SIGKILL to filters and backend
87 * canceled Send SIGTERM to filters and backend
91 * Finalize clears the printer <-> job association, deletes the status
92 * buffer, closes all of the pipes, etc. and doesn't get run until all of
93 * the print processes are finished.
95 * UNLOADING OF JOBS (cupsdUnloadCompletedJobs)
97 * We unload the job attributes when they are not needed to reduce overall
98 * memory consumption. We don't unload jobs where job->state_value <
99 * IPP_JOB_STOPPED, job->printer != NULL, or job->access_time is recent.
101 * STARTING OF JOBS (start_job)
103 * When a job is started, a status buffer, several pipes, a security
104 * profile, and a backend process are created for the life of that job.
105 * These are shared for every file in a job. For remote print jobs, the
106 * IPP backend is provided with every file in the job and no filters are
109 * The job->printer member tracks which printer is printing a job, which
110 * can be different than the destination in job->dest for classes. The
111 * printer object also has a job pointer to track which job is being
114 * PRINTING OF JOB FILES (cupsdContinueJob)
116 * Each file in a job is filtered by 0 or more programs. After getting the
117 * list of filters needed and the total cost, the job is either passed or
118 * put back to the processing state until the current FilterLevel comes down
119 * enough to allow printing.
121 * If we can print, we build a string for the print options and run each of
122 * the filters, piping the output from one into the next.
124 * JOB STATUS UPDATES (update_job)
126 * The update_job function gets called whenever there are pending messages
127 * on the status pipe. These generally are updates to the marker-*,
128 * printer-state-message, or printer-state-reasons attributes. On EOF,
129 * finalize_job is called to clean up.
131 * FINALIZING JOBS (finalize_job)
133 * When all filters and the backend are done, we set the job state to
134 * completed (no errors), aborted (filter errors or abort-job policy),
135 * pending-held (auth required or retry-job policy), or pending
136 * (retry-current-job or stop-printer policies) as appropriate.
138 * Then we close the pipes and free the status buffers and profiles.
140 * JOB FILE COMPLETION (process_children in main.c)
142 * For multiple-file jobs, process_children (in main.c) sees that all
143 * filters have exited and calls in to print the next file if there are
144 * more files in the job, otherwise it waits for the backend to exit and
145 * update_job to do the cleanup.
