80 | * Design Notes for Job Management | |
81 | * ------------------------------- | |
82 | * | |
83 | * STATE CHANGES | |
84 | * | |
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 | |
90 | * aborted Finalize | |
91 | * completed Finalize | |
92 | * | |
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. | |
96 | * | |
97 | * UNLOADING OF JOBS (cupsdUnloadCompletedJobs) | |
98 | * | |
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. | |
102 | * | |
103 | * STARTING OF JOBS (start_job) | |
104 | * | |
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 | |
109 | * run. | |
110 | * | |
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 | |
114 | * printed. | |
115 | * | |
116 | * PRINTING OF JOB FILES (cupsdContinueJob) | |
117 | * | |
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. | |
122 | * | |
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. | |
125 | * | |
126 | * JOB STATUS UPDATES (update_job) | |
127 | * | |
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. | |
132 | * | |
133 | * FINALIZING JOBS (finalize_job) | |
134 | * | |
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. | |
139 | * | |
140 | * Then we close the pipes and free the status buffers and profiles. | |
141 | * | |
142 | * JOB FILE COMPLETION (process_children in main.c) | |
143 | * | |
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. | |
