Tue, 09 Nov 2010 21:52:05 +0100 wenzelm private counter, to keep externalized ids a bit smaller;
Fri, 10 Sep 2010 14:54:08 +0200 wenzelm Future.promise: more robust treatment of concurrent abort vs. fulfill (amending 047c96f41455);
Thu, 09 Sep 2010 17:20:27 +0200 wenzelm more abstract treatment of interrupts in structure Exn -- hardly ever need to mention Interrupt literally;
Tue, 20 Jul 2010 17:35:42 +0200 wenzelm back to more strict dependencies, even for canceled groups (reverting parts of 02936e77a07c);
Mon, 31 May 2010 21:06:57 +0200 wenzelm modernized some structure names, keeping a few legacy aliases;
Fri, 19 Feb 2010 22:25:26 +0100 wenzelm eliminated opaque signature matching -- tends to cause problems with toplevel pp for abstract types;
Sat, 06 Feb 2010 16:32:34 +0100 wenzelm removed unused "boundary" of Table/Graph.get_first;
Wed, 06 Jan 2010 18:14:16 +0100 wenzelm eliminated cache, which complicates the code without making a real difference (NB: deque_towards often disrupts caching, and daisy-chaining of workers already reduces queue overhead);
Wed, 06 Jan 2010 15:07:56 +0100 wenzelm tasks of canceled groups are considered "ready" -- enables to purge the queue from tasks depending on unfinished promises (also improves general reactivity);
Tue, 05 Jan 2010 23:38:10 +0100 wenzelm added Future.promise/fulfill -- promised futures that are fulfilled by external means;
Thu, 01 Oct 2009 16:27:13 +0200 wenzelm added Task_Queue.depend (again) -- light-weight version for transitive graph;
Wed, 30 Sep 2009 22:20:58 +0200 wenzelm eliminated redundant bindings;
Tue, 28 Jul 2009 14:54:53 +0200 wenzelm group status: Synchronized.var;
Tue, 28 Jul 2009 14:43:46 +0200 wenzelm tuned;
Tue, 28 Jul 2009 14:35:27 +0200 wenzelm Task_Queue.dequeue: explicit thread;
Mon, 27 Jul 2009 15:06:33 +0200 wenzelm dequeue_towards: always return active tasks;
Mon, 27 Jul 2009 13:32:23 +0200 wenzelm removed unused low-level interrupts;
Mon, 27 Jul 2009 12:24:27 +0200 wenzelm tuned signature;
Mon, 27 Jul 2009 12:00:02 +0200 wenzelm enqueue/finish: return minimal/maximal state of this task;
Sat, 25 Jul 2009 14:58:45 +0200 wenzelm dequeue_towards: need to try imm_preds as well;
Sat, 25 Jul 2009 14:18:26 +0200 wenzelm enqueue: maintain transitive closure, which simplifies dequeue_towards;
Tue, 21 Jul 2009 20:37:31 +0200 wenzelm support for nested groups -- cancellation is propagated to peers and subgroups;
Tue, 21 Jul 2009 15:25:22 +0200 wenzelm propagate exceptions within future groups;
Tue, 21 Jul 2009 10:23:16 +0200 wenzelm tuned dequeu_towards: try immediate tasks before expensive all_preds;
Sun, 19 Jul 2009 14:14:25 +0200 wenzelm recovered a version of dequeue_towards (cf. bb7b5a5942c7);
Sat, 18 Jul 2009 22:51:29 +0200 wenzelm added group_id;
Thu, 09 Jul 2009 22:01:41 +0200 wenzelm renamed functor TableFun to Table, and GraphFun to Graph;
Sun, 14 Jun 2009 23:25:49 +0200 wenzelm removed obsolete depend, add_job_acyclic;
Sat, 13 Jun 2009 19:40:37 +0200 wenzelm simplified join_results: no longer work "towards" deps, which simplifies task queue management and maintains strict bottom up discipline (without "transfer of priority" to required futures);
Tue, 06 Jan 2009 13:43:17 +0100 wenzelm added is_valid;
