31 | * Design Notes for Job Management | |
32 | * ------------------------------- | |

36 | * pending Do nothing/check jobs | |
37 | * pending-held Send SIGTERM to filters and backend | |
38 | * processing Do nothing/start job | |
39 | * stopped Send SIGKILL to filters and backend | |
40 | * canceled Send SIGTERM to filters and backend | |
41 | * aborted Finalize | |
42 | * completed Finalize | |
43 | * | |
44 | * Finalize clears the printer <-> job association, deletes the status | |
45 | * buffer, closes all of the pipes, etc. and doesn't get run until all of | |
46 | * the print processes are finished. | |
47 | * | |
48 | * UNLOADING OF JOBS (cupsdUnloadCompletedJobs) | |
49 | * | |
50 | * We unload the job attributes when they are not needed to reduce overall | |
51 | * memory consumption. We don't unload jobs where job->state_value < | |
52 | * IPP_JOB_STOPPED, job->printer != NULL, or job->access_time is recent. | |
53 | * | |
54 | * STARTING OF JOBS (start_job) | |
55 | * | |
56 | * When a job is started, a status buffer, several pipes, a security | |
57 | * profile, and a backend process are created for the life of that job. | |
58 | * These are shared for every file in a job. For remote print jobs, the | |
59 | * IPP backend is provided with every file in the job and no filters are | |
60 | * run. | |
61 | * | |
62 | * The job->printer member tracks which printer is printing a job, which | |
63 | * can be different than the destination in job->dest for classes. The | |
64 | * printer object also has a job pointer to track which job is being | |
65 | * printed. | |
66 | * | |
67 | * PRINTING OF JOB FILES (cupsdContinueJob) | |
68 | * | |
69 | * Each file in a job is filtered by 0 or more programs. After getting the | |
70 | * list of filters needed and the total cost, the job is either passed or | |
71 | * put back to the processing state until the current FilterLevel comes down | |
72 | * enough to allow printing. | |
73 | * | |
74 | * If we can print, we build a string for the print options and run each of | |
75 | * the filters, piping the output from one into the next. | |
76 | * | |
77 | * JOB STATUS UPDATES (update_job) | |
78 | * | |
79 | * The update_job function gets called whenever there are pending messages | |
80 | * on the status pipe. These generally are updates to the marker-*, | |
81 | * printer-state-message, or printer-state-reasons attributes. On EOF, | |
82 | * finalize_job is called to clean up. | |
83 | * | |
84 | * FINALIZING JOBS (finalize_job) | |
85 | * | |
86 | * When all filters and the backend are done, we set the job state to | |
87 | * completed (no errors), aborted (filter errors or abort-job policy), | |
88 | * pending-held (auth required or retry-job policy), or pending | |
89 | * (retry-current-job or stop-printer policies) as appropriate. | |
90 | * | |
91 | * Then we close the pipes and free the status buffers and profiles. | |
92 | * | |
93 | * JOB FILE COMPLETION (process_children in main.c) | |
94 | * | |
95 | * For multiple-file jobs, process_children (in main.c) sees that all | |
96 | * filters have exited and calls in to print the next file if there are | |
97 | * more files in the job, otherwise it waits for the backend to exit and | |
98 | * update_job to do the cleanup. | |
