updated docs

renamed "kill" subcommand to avoid clash with "kill" keyword (which confuses Proof General and results in strange syntax highlighting)

tweaked fudge factor

more NEWS;

document 'locale_deps';

prefer old graph browser in Isabelle/jEdit, which still produces better layout; clarified print mode "active_graph": allow to switch "browser" vs. "graphview" uniformly; tuned signature;

more formal inlining of system information;

tuned message -- suppress inlined system information;

merged

tuned

avoid long enumeration of HO unifiers;

disable search dialog pool on all platforms -- to prevent GUI synchronization problems seen on KDE (e.g. Kubuntu 12.10);

merged

maintain session index on Scala side, for more determistic results; removed unused HTML operations;

close formulas in the natural order, not its reverse -- so that Skolem arguments appear in the right order in Isar proofs

use new skolemizer for reconstructing skolemization steps in Isar proofs (because the old skolemizer messes up the order of the Skolem arguments)

rename variable in binder, not just in body

swap Vampire's Skolem arguments to bring them in line with what E and metis's new skolemizer do (helps Isar proof reconstruction in some cases)

tuned comment

NEWS: ML runtime statistics;

merged

more interesting fields;

always enable Future.ML_statistics where this makes sense -- runtime overhead should be negligible;

improved Monitor_Dockable, based on ML_Statistics operations; tuned signature;

get rid of two-year-old hack, now that the "metis" skolemizer no longer gets stuck in HO unification

avoid explosion in higher-order unification algorithm

avoid repeated calls to metis from "resolve_tac" in case of ultimate failure

tuned comment

merged

added standard_frames convenience;

some grouping of standard fields; tuned signature;

some support for chart drawing;

some support for ML statistics content interpretation;

moved files;

moved files;

ML runtime statistics: read properties from build log;

support File.read_gzip as well, in accordance to File.write_gzip; tuned signature;

inline ML statistics into build log;

removed outdated comment;

enable Z3 for full test (cf. 6f48853f08d5);

removed old, unused code

removed whitespace

removed duplicate code

use rpair to avoid swap

generate "obtain" steps corresponding to skolemization inferences

keep E's and Vampire's skolemization steps

tuning

fixed oversensitive Skolem handling (cf. eaa540986291)

added "obtain" to Isar proof construction data structure

tuning

properly take the existential closure of skolems

use "Lazy" to simplify control flow a bit and guarantee single evaluation (at most)

tuning

added 112 to list of known Z3 error codes

actually run Z3 for "SMT_Tests" when "ISABELLE_FULL_TEST" is enabled

added missing certificate file to "ROOT"

more robust report_status: tolerate ML_statistics even if ignored right now, e.g. in batch build;

more liberal edit_control_style: include preceeding control symbol to reduce potential for user surprise;

regenerate certificates -- and use oracle in a few cases where the Z3 proof parser can't deal with Z3 3.2 proofs

Z3's soft timeout is expressed in ms, not in s -- this explains the frequenty "error code 112" failures we had recently
