To quickly assess the difficulty of the text, read a short excerpt:
If j is extincted then re'Spond 'aborted' and go to stage 4. 3. 2. If lockeasy (Lijk) = 'granted' then respond 'granted' and remove edges from the wfg from j with label i; go to stage 4. (The reason lock- easy is called again is that changes in stage 2 might "enable" Lijk to proceed. ) 3. 3. Set response to 'postponed' and enqueue j on i's wait queue. Stage 4 If j holds aut number of locks (cut is a parameter of the system) then extinction (j) is performed. We then consider j to be aompZeted. W...hen cut = °°, no completions ever take place. Extinction : It handles the extinction (due to deadlock or completion) of active (i. E. , not-everywhere blocked) transactions. It is called with transaction j as argument. All edges in the wfg associated with j are -13- deleted. All items are scanned, j is eliminated from all wait emd hold queues. Finally, for all items i in which j either held locks or was waiting, advanceq(i) is performed, since j's extinction may enable other transactions to proceed.
