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