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