Tue, 23 Jul 2019 12:07:50 +0200 wenzelm proof terms are always constructed sequentially;
Thu, 03 Jan 2019 14:12:44 +0100 wenzelm clarified signature: more types;
Fri, 27 Jul 2018 17:32:16 +0200 wenzelm proper adjust_maxidx: assms could have maxidx >= 0, e.g. from command "subgoal premises";
Wed, 09 May 2018 20:45:57 +0200 wenzelm clarified future scheduling parameters, with support for parallel_limit;
Tue, 24 Apr 2018 11:03:51 +0200 wenzelm clarified modules;
Sun, 25 Feb 2018 15:44:46 +0100 wenzelm eliminated ASCII syntax from Pure bootstrap;
Mon, 10 Apr 2017 21:05:31 +0200 wenzelm tuned signature;
Wed, 14 Dec 2016 16:59:41 +0100 wenzelm always close derivation, for significantly improved performance without parallel proofs;
Tue, 13 Dec 2016 11:51:42 +0100 wenzelm more symbols;
Fri, 30 Oct 2015 17:14:30 +0100 wenzelm tuned signature -- clarified modules;
Fri, 23 Oct 2015 17:17:11 +0200 wenzelm clarified modules;
Sun, 16 Aug 2015 18:19:30 +0200 wenzelm prefer theory_id operations;
Tue, 28 Jul 2015 20:05:53 +0200 wenzelm proper context;
Tue, 14 Jul 2015 19:01:46 +0200 wenzelm more aggressive compaction of multi-goal proof terms (see also a8babbb6d5ea, 4dd0ba632e40);
Tue, 14 Jul 2015 11:29:43 +0200 wenzelm normalize proof before splitting conjunctions, according to Proof.conclude_goal (see also 4dd0ba632e40) -- may reduce general resource usage;
Wed, 08 Jul 2015 19:28:43 +0200 wenzelm Variable.focus etc.: optional bindings provided by user;
Sun, 05 Jul 2015 15:02:30 +0200 wenzelm simplified Thm.instantiate and derivatives: the LHS refers to non-certified variables -- this merely serves as index into already certified structures (or is ignored);
Fri, 06 Mar 2015 17:32:20 +0100 wenzelm clarified context;
Fri, 06 Mar 2015 15:58:56 +0100 wenzelm Thm.cterm_of and Thm.ctyp_of operate on local context;

Wed, 04 Mar 2015 19:53:18 +0100 wenzelm tuned signature -- prefer qualified names;
Mon, 23 Feb 2015 14:50:30 +0100 wenzelm Goal.prove_multi is superseded by the fully general Goal.prove_common;
Tue, 10 Feb 2015 14:48:26 +0100 wenzelm proper context for resolve_tac, eresolve_tac, dresolve_tac, forward_tac etc.;
Mon, 10 Nov 2014 21:49:48 +0100 wenzelm proper context for assume_tac (atac remains as fall-back without context);
Sat, 08 Nov 2014 21:31:51 +0100 wenzelm optional proof context for unify operations, for the sake of proper local options;
Thu, 30 Oct 2014 16:20:46 +0100 wenzelm eliminated aliases;
Tue, 19 Aug 2014 18:11:04 +0200 wenzelm clarified modules;
Tue, 19 Aug 2014 17:00:44 +0200 wenzelm added PARALLEL_ALLGOALS convenience;
Fri, 21 Mar 2014 20:33:56 +0100 wenzelm more qualified names;
Tue, 18 Feb 2014 20:32:58 +0100 wenzelm tuned message;
Sat, 11 Jan 2014 21:39:21 +0100 wenzelm reactivate Thm.check_hyps, after adapting AFP/Datatype_Order_Generator (see AFP/b7e389b5765c);
Sat, 11 Jan 2014 20:06:31 +0100 wenzelm check_hyps for attribute application (still inactive, due to non-compliant tools);
Sat, 11 Jan 2014 17:05:03 +0100 wenzelm clarified context;
Fri, 10 Jan 2014 23:42:18 +0100 wenzelm disable Thm.check_hyps for now, due to remaining problems with AFP/Datatype_Order_Generator and AFP/Psi_Calculi (because of HOL-Nominal 'equivariance');
Fri, 10 Jan 2014 21:37:28 +0100 wenzelm more elementary management of declared hyps, below structure Assumption;
Fri, 10 Jan 2014 16:20:06 +0100 wenzelm explicit check of background theory;
Tue, 31 Dec 2013 14:29:16 +0100 wenzelm proper context for norm_hhf and derived operations;
Sat, 14 Dec 2013 17:28:05 +0100 wenzelm proper context for basic Simplifier operations: rewrite_rule, rewrite_goals_rule, rewrite_goals_tac etc.;
Sat, 23 Nov 2013 17:15:44 +0100 wenzelm more uniform / rigid checking of Goal.prove_common vs. Proof.conclude_goal -- NB: Goal.prove_common cannot check hyps right now, e.g. due to undeclared Simplifier prems;
Sun, 25 Aug 2013 20:32:26 +0200 wenzelm maintain goal forks as part of global execution;
Sun, 25 Aug 2013 17:04:22 +0200 wenzelm simplified Goal.forked_proofs: status is determined via group instead of dummy future (see also Pure/PIDE/execution.ML);
Sun, 25 Aug 2013 16:03:12 +0200 wenzelm discontinued parallel_subproofs_saturation and related internal counters (superseded by parallel_subproofs_threshold and timing information);
Wed, 31 Jul 2013 13:00:42 +0200 wenzelm clarified priority of "skipped" proofs, which might take long but do not produce relevant information (potential conflict of quick interactive feedback vs. performance in batch mode);
Mon, 29 Jul 2013 18:59:58 +0200 wenzelm keep memo_exec execution running, which is important to cancel goal forks eventually;
Mon, 29 Jul 2013 14:18:57 +0200 wenzelm actually purge removed goal futures -- avoid memory leak;
Mon, 29 Jul 2013 13:43:43 +0200 wenzelm tuned -- less redundant data structure;
Mon, 29 Jul 2013 13:24:15 +0200 wenzelm discontinued notion of "stable" result -- running execution is never canceled;
Sat, 27 Jul 2013 20:27:25 +0200 wenzelm clarified Goal.stable_futures after 00170ef1dc39: running tasks are considered stable, without potentially blocking join;
Sat, 27 Jul 2013 16:35:51 +0200 wenzelm standardized aliases;
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;
Mon, 13 May 2013 12:40:17 +0200 wenzelm retain goal display options when printing error messages, to avoid breakdown for huge goals;
