29 * Manipulation routines for Job Control Records and
30 * handling of last_jobs_list.
32 * Kern E. Sibbald, December 2000
34 * These routines are thread safe.
36 * The job list routines were re-written in May 2005 to
37 * eliminate the global lock while traversing the list, and
38 * to use the dlist subroutines. The locking is now done
39 * on the list each time the list is modified or traversed.
40 * That is it is "micro-locked" rather than globally locked.
41 * The result is that there is one lock/unlock for each entry
42 * in the list while traversing it rather than a single lock
43 * at the beginning of a traversal and one at the end. This
44 * incurs slightly more overhead, but effectively eliminates
45 * the possibilty of race conditions. In addition, with the
46 * exception of the global locking of the list during the
47 * re-reading of the config file, no recursion is needed.
