Wed, 05 Aug 2020 12:42:43 +0200 wenzelm more robust: insist in finished future;
Thu, 06 Sep 2018 14:08:35 +0200 wenzelm simplified signature (again, see 751bcf0473a7): e.g. relevant for non-Isabelle ML environments;
Sat, 01 Sep 2018 16:08:54 +0200 wenzelm more robust: memoize interrupt (e.g. resource problem) -- avoid multiple attempts;
Sat, 01 Sep 2018 14:25:03 +0200 wenzelm more robust eval_result: enforce finished result stemming from previous run_process, fail if that was interrupted (e.g. due to resource problems);
Sat, 28 Jul 2018 16:08:04 +0200 wenzelm eliminated non-monotomnic Lazy.is_pending: Result may return to Expr due to Interrupt;
Sat, 28 Jul 2018 15:09:37 +0200 wenzelm unused;
Fri, 06 Jul 2018 15:35:48 +0200 wenzelm more frugal assignment of lazy value: fewer mutexes, condvars;
Thu, 05 Jul 2018 23:08:01 +0200 wenzelm store immutable result: fewer refs, mutexes, condvars;
Wed, 09 May 2018 20:45:57 +0200 wenzelm clarified future scheduling parameters, with support for parallel_limit;
Mon, 19 Feb 2018 18:12:28 +0100 wenzelm tuned: more parallel;
Mon, 19 Feb 2018 18:01:36 +0100 wenzelm clarified modules;
Mon, 19 Feb 2018 14:18:29 +0100 wenzelm clarified operations;
Mon, 19 Feb 2018 10:05:37 +0100 wenzelm more operations;
Mon, 23 Oct 2017 14:12:09 +0200 wenzelm minor performance tuning: avoid mutable variable for plain value, e.g. relevant for GC;
Thu, 22 Jun 2017 21:10:13 +0200 wenzelm consolidate proofs more simultaneously;
Thu, 22 Jun 2017 15:20:32 +0200 wenzelm more informative task_statistics;
Thu, 22 Jun 2017 14:27:13 +0200 wenzelm more informative task_statistics;
Sat, 09 Apr 2016 14:00:23 +0200 wenzelm clarified bootstrap;
Wed, 06 Apr 2016 17:16:30 +0200 wenzelm tuned signature;
Sat, 02 Apr 2016 22:38:26 +0200 wenzelm tuned signature;
Sat, 02 Apr 2016 21:10:07 +0200 wenzelm careful export of type-dependent functions, without losing their special status;
Fri, 18 Mar 2016 16:26:35 +0100 wenzelm clarified modules;
Sun, 11 Jan 2015 13:12:47 +0100 wenzelm do not crash into already running exec, instead join its lazy result in the subsequent step (amending 59f1591a11cb);
Sun, 28 Dec 2014 22:10:09 +0100 wenzelm back to full synchronization (cf. eb3e399f5b9f);
Sun, 28 Dec 2014 21:34:45 +0100 wenzelm eliminated Document.execution frontier (again, see 627fb639a2d9): just run into older execution, potentially stalling worker thread, but without global delay due to long-running tasks (notably sledgehammer);
Sun, 28 Dec 2014 12:18:01 +0100 wenzelm more thorough Lazy.is_finished;
Thu, 18 Dec 2014 16:13:54 +0100 wenzelm peek value without synchronization;
Thu, 12 Apr 2012 11:28:36 +0200 wenzelm partial revert of 8a179a0493e3 -- expose failure status of result (potentially via group) instead of isolated interrupt;
Wed, 11 Apr 2012 13:49:09 +0200 wenzelm more robust Future.fulfill wrt. duplicate assignment and interrupt;
Tue, 23 Aug 2011 17:43:06 +0200 wenzelm tuned signature;
