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;
Thu, 30 Aug 2012 21:23:04 +0200 wenzelm refined treatment of forked proofs at transaction boundaries, including proof commands (see also 7ee000ce5390);
Thu, 30 Aug 2012 15:26:37 +0200 wenzelm refined status of forked goals;
Wed, 29 Aug 2012 11:48:45 +0200 wenzelm renamed Position.str_of to Position.here;
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;
Wed, 10 Aug 2011 16:05:14 +0200 wenzelm future_job: explicit indication of interrupts;
Wed, 27 Apr 2011 21:50:04 +0200 wenzelm clarified Variable.focus vs. Variable.focus_cterm -- eliminated clone;
Sat, 16 Apr 2011 23:38:25 +0200 wenzelm enable PARALLEL_GOALS more liberally, unlike forked proofs (cf. 34b9652b2f45);
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;
Tue, 22 Feb 2011 19:44:15 +0100 wenzelm scale parallel_proofs_threshold with max_threads_value to improve saturation of cores;
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;
Mon, 31 Jan 2011 22:57:01 +0100 wenzelm support named tasks, for improved tracing;
Fri, 17 Dec 2010 17:08:56 +0100 wenzelm renamed structure MetaSimplifier to raw_Simplifer, to emphasize its meaning;
Fri, 03 Sep 2010 21:13:53 +0200 wenzelm pretty_goals: turned some global references and function arguments into configuration options (goals_limit = 10, goals_total = true, show_main_goal = false) depending on the context;
Mon, 30 Aug 2010 15:19:39 +0200 wenzelm tuned messages: discontinued spurious full-stops (messages are occasionally composed unexpectedly);
Sun, 08 Aug 2010 19:36:31 +0200 wenzelm explicitly distinguish Output.status (essential feedback) vs. Output.report (useful markup);
Fri, 06 Aug 2010 14:35:04 +0200 wenzelm removed obsolete Goal.local_future_enforced: Toplevel.run_command is no longer interactive, so Goal.local_future_enabled is sufficient (cf. 349e9223c685 and e07dacec79e7);
Sun, 04 Jul 2010 21:01:22 +0200 wenzelm general Future.report -- also for Toplevel.async_state;
Sat, 29 May 2010 19:46:29 +0200 wenzelm explicit markup for forked goals, as indicated by Goal.fork;
Mon, 03 May 2010 15:34:55 +0200 wenzelm simplified primitive Thm.future: more direct theory check, do not hardwire strip_shyps here;
Mon, 03 May 2010 14:25:56 +0200 wenzelm renamed ProofContext.init to ProofContext.init_global to emphasize that this is not the real thing;
Sat, 20 Mar 2010 17:33:11 +0100 wenzelm renamed varify/unvarify operations to varify_global/unvarify_global to emphasize that these only work in a global situation;
Sun, 07 Feb 2010 19:33:34 +0100 wenzelm renamed old-style Drule.standard to Drule.export_without_context, to emphasize that this is in no way a standard operation;
Thu, 19 Nov 2009 17:29:39 +0100 wenzelm future_result: purge flexflex pairs, which should normally be trivial anyway -- prevent Thm.future_result from complaining about tpairs;
Wed, 30 Sep 2009 22:26:47 +0200 wenzelm PARALLEL_GOALS: proper scope for exception FAILED, with dummy argument to prevent its interpretation as variable;
Tue, 29 Sep 2009 11:49:22 +0200 wenzelm explicit indication of Unsynchronized.ref;
Wed, 12 Aug 2009 00:26:01 +0200 wenzelm added PARALLEL_CHOICE, PARALLEL_GOALS;
Tue, 28 Jul 2009 16:30:23 +0200 wenzelm eliminated separate Future.enabled -- let Future.join fail explicitly in critical section, instead of entering sequential mode silently;
Sun, 26 Jul 2009 13:12:52 +0200 wenzelm Goal.finish: explicit context for printing;
Sat, 25 Jul 2009 10:31:27 +0200 wenzelm renamed structure Display_Goal to Goal_Display;
Thu, 23 Jul 2009 16:52:16 +0200 wenzelm clarified pretty_goals, pretty_thm_aux: plain context;
Mon, 20 Jul 2009 21:20:09 +0200 wenzelm moved pretty_goals etc. to Display_Goal (required by tracing tacticals);
Mon, 20 Jul 2009 00:37:39 +0200 wenzelm Proof.future_proof: declare all assumptions as well;
Sun, 19 Jul 2009 19:24:04 +0200 wenzelm parallel_proofs: more fine-grained control with optional parallel checking of nested Isar proofs;
Sun, 19 Jul 2009 18:02:40 +0200 wenzelm more abstract Future.is_worker;
Sun, 19 Jul 2009 14:15:47 +0200 wenzelm future_result: explicitly impose Variable.sorts_of again;
