Fri, 19 Jul 2013 17:58:57 +0200 wenzelm just one option "skip_proofs", without direct access within the editor (it makes document processing stateful without strong reasons -- monotonic updates already handle goal forks smoothly);
Thu, 18 Jul 2013 13:12:54 +0200 wenzelm immutable theory values with full stamp record of every update (increase of stamp size for HOL: 20000 -> 100000, JinjaThreads: 65000 -> 300000) -- minimal measurable impact on inference kernel performance;
Fri, 12 Jul 2013 12:04:16 +0200 wenzelm clarified execution: maintain running execs only, check "stable" separately via memo (again);
Tue, 02 Jul 2013 14:48:01 +0200 wenzelm clarified Proofterm.proofs vs. Goal.skip_proofs;
Thu, 27 Jun 2013 10:08:41 +0200 wenzelm more scalable PARALLEL_GOALS, using more elementary retrofit;
Wed, 26 Jun 2013 21:48:23 +0200 wenzelm less intrusive SELECT_GOAL: merely rearrange subgoals without detaching goal state, and thus preserve maxidx context;
Wed, 26 Jun 2013 11:54:45 +0200 wenzelm tuned signature;
Wed, 29 May 2013 18:25:11 +0200 wenzelm tuned signature -- more explicit flags for low-level Thm.bicompose;
Tue, 21 May 2013 17:55:28 +0200 wenzelm proper options;
Fri, 17 May 2013 20:41:45 +0200 wenzelm proper option quick_and_dirty;

Wed, 27 Mar 2013 16:38:25 +0100 wenzelm more ambitious Goal.skip_proofs: covers Goal.prove forms as well, and do not insist in quick_and_dirty (for the sake of Isabelle/jEdit);
Wed, 27 Mar 2013 14:50:30 +0100 wenzelm clarified Skip_Proof.cheat_tac: more standard tactic;
Wed, 27 Mar 2013 14:19:18 +0100 wenzelm tuned signature and module arrangement;
Wed, 13 Mar 2013 21:25:08 +0100 wenzelm clarified parallel_subproofs_saturation (blind guess) vs. parallel_subproofs_threshold (precient timing estimate);
Mon, 25 Feb 2013 17:47:32 +0100 wenzelm more explicit Goal.shutdown_futures;
Tue, 19 Feb 2013 17:55:26 +0100 wenzelm improved scheduling of forked proofs, based on elapsed time estimate (from last run via session log file);
Thu, 14 Feb 2013 15:34:33 +0100 wenzelm tuned signature -- legacy packages might want to fork proofs as well;
Wed, 13 Feb 2013 21:53:02 +0100 wenzelm clarified default according to etc/options;
Sat, 19 Jan 2013 22:17:26 +0100 wenzelm always close derivation at the bottom of forked proofs (despite increased non-determinism of proof terms) -- improve parallel performance by avoiding dynamic dependency within large Isar proofs, e.g. Slicing/JinjaVM/SemanticsWF.thy in AFP/bf9b14cbc707;
Fri, 18 Jan 2013 16:20:09 +0100 wenzelm added "tasks_proof" statistics, via slighly odd global reference Future.forked_proofs (NB: Future.report_status is intertwined with scheduler thread);
Wed, 16 Jan 2013 20:41:29 +0100 wenzelm identify future results more carefully, to avoid odd duplication of error messages, notably from forked goals;
Wed, 16 Jan 2013 16:26:36 +0100 wenzelm more explicit treatment of (optional) exception properties, notably for "serial" -- avoid conflict with startPosition = offset;
Sun, 25 Nov 2012 19:49:24 +0100 wenzelm Isabelle-specific implementation of quasi-abstract markup elements -- back to module arrangement before d83797ef0d2d;
Thu, 18 Oct 2012 19:58:30 +0200 wenzelm more basic Goal.reset_futures as snapshot of implicit state;
Wed, 17 Oct 2012 21:04:51 +0200 wenzelm more robust Session.finish (batch mode): use Goal.finish_futures to exhibit remaining failures of disconnected goal forks (e.g. from unnamed theorems) and Goal.cancel_futures the purge the persistent state;
Sat, 13 Oct 2012 19:53:04 +0200 wenzelm some attempts to unify/simplify pretty_goal;
Sat, 13 Oct 2012 16:19:16 +0200 wenzelm tuned signature;
Fri, 12 Oct 2012 13:55:13 +0200 wenzelm no special treatment of errors inside goal forks without transaction id, to avoid duplication in plain build with sequential log, for example;
Fri, 12 Oct 2012 13:46:41 +0200 wenzelm do not treat interrupt as error here, to avoid confusion in log etc.;
Sat, 01 Sep 2012 19:27:28 +0200 wenzelm central management of forked goals wrt. transaction id;
Fri, 31 Aug 2012 15:25:26 +0200 wenzelm more informative error message from failed goal forks (violating old-style TTY protocol!);
Fri, 31 Aug 2012 14:35:04 +0200 wenzelm more markup for failed goal forks, reusing "bad";
Fri, 31 Aug 2012 13:23:25 +0200 wenzelm further refinement of command status, to accomodate forked proofs;

Tue, 10 Apr 2012 20:42:17 +0200 wenzelm tuned future priorities: print 0, goal ~1, execute ~2;
Fri, 11 Nov 2011 16:25:32 +0100 wenzelm depth-first proof forking for improved locality (wrt. cancellation and overall memory usage);
Sat, 05 Nov 2011 15:00:49 +0100 wenzelm added Logic.varify_types_global/unvarify_types_global, which avoids somewhat expensive Term.map_types;
Fri, 19 Aug 2011 18:01:23 +0200 wenzelm tuned;
Wed, 10 Aug 2011 16:24:39 +0200 wenzelm Goal.forked: clarified handling of interrupts;

Sat, 16 Apr 2011 22:21:34 +0200 wenzelm refined PARALLEL_GOALS;
Sat, 16 Apr 2011 15:47:52 +0200 wenzelm modernized structure Proof_Context;

Fri, 18 Feb 2011 16:11:58 +0100 wenzelm less verbose tracing;
Fri, 04 Feb 2011 17:11:00 +0100 wenzelm parallelization of nested Isar proofs is subject to Goal.parallel_proofs_threshold;
Wed, 02 Feb 2011 15:04:09 +0100 wenzelm maintain Task_Queue.group within Task_Queue.task;
Mon, 31 Jan 2011 23:53:07 +0100 wenzelm more specific Goal.fork_name;
Mon, 31 Jan 2011 23:02:53 +0100 wenzelm tuned signature;
