2011-10-16 wenzelm 2011-10-16 added Term.dummy_pattern conveniences;
2011-08-20 wenzelm 2011-08-20 more direct balanced version Ord_List.unions;
2011-08-20 wenzelm 2011-08-20 reverted to join_bodies/join_proofs based on fold_body_thms to regain performance (escpecially of HOL-Proofs) -- see also aa9c1e9ef2ce and 4e2abb045eac;
2011-08-20 wenzelm 2011-08-20 tuned future priorities (again);
2011-08-20 wenzelm 2011-08-20 clarified fulfill_norm_proof: no join_thms yet; clarified priority of fulfill_proof_future, which is followed by explicit join_thms; explicit Thm.future_body_of without join yet; tuned Thm.future_result: join_promises without fulfill_norm_proof;
2011-08-20 wenzelm 2011-08-20 added Future.joins convenience; clarified Future.map: based on Future.cond_forks;
2011-08-19 wenzelm 2011-08-19 incremental Proofterm.join_body, with join_thms step in fulfill_norm_proof -- avoid full graph traversal of former Proofterm.join_bodies;
2011-08-19 wenzelm 2011-08-19 tuned;
2011-08-10 wenzelm 2011-08-10 avoid OldTerm operations -- with subtle changes of semantics;
2011-08-10 wenzelm 2011-08-10 avoid OldTerm operations -- with subtle changes of semantics;
2011-08-10 wenzelm 2011-08-10 future_job: explicit indication of interrupts;

2011-01-31 wenzelm 2011-01-31 tuned signature; tuned vacous forks;
2011-01-31 wenzelm 2011-01-31 support named tasks, for improved tracing;
2011-01-31 wenzelm 2011-01-31 more direct Future.bulk, which potentially reduces overhead for Par_List; tuned signature;

2010-09-01 haftmann 2010-09-01 replaced Table.map' by Table.map
2010-06-02 wenzelm 2010-06-02 always unconstrain thm proofs;
2010-06-02 wenzelm 2010-06-02 normalize and postprocess proof body in a separate future, taking care of platforms without multithreading (greately improves parallelization in general without the overhead of promised proofs, cf. usedir -q 0);
2010-06-01 berghofe 2010-06-01 merged
2010-06-01 berghofe 2010-06-01 - outer_constraints with original variable names, to ensure that argsP is consistent with args - Exported map_proof_same, added implies_intr_proof' and forall_intr_proof' - Rewriting procedures used by rewrite_proof can now access hypotheses - Finally enabled unconstrain
2010-05-31 wenzelm 2010-05-31 modernized some structure names, keeping a few legacy aliases;
2010-05-14 wenzelm 2010-05-14 added Proofterm.unconstrain_thm_proof for Thm.unconstrainT -- loosely based on the version by krauss/schropp;
2010-05-13 wenzelm 2010-05-13 conditionally unconstrain thm proofs -- loosely based on the version by krauss/schropp;
2010-05-13 wenzelm 2010-05-13 avoid redundant rebinding of name/prop -- probably introduced accidentally in 80bb72a0f577;
2010-05-13 wenzelm 2010-05-13 raise Fail uniformly for proofterm errors, which appear to be rather low-level;
2010-05-13 wenzelm 2010-05-13 unconstrainT operations on proofs, according to krauss/schropp;
2010-05-13 wenzelm 2010-05-13 added Proofterm.get_name variants according to krauss/schropp; tuned signature;
2010-05-08 wenzelm 2010-05-08 tuned signature;
2010-05-08 wenzelm 2010-05-08 added of_sort_proof according to krauss/schropp, with slightly more direct canonical_instance;
2010-05-08 wenzelm 2010-05-08 back-patching of axclass proofs;
2010-05-07 wenzelm 2010-05-07 strip_shyps_proof: dummy TFrees are called "'dummy" as in del_conflicting_tvars below;
2010-05-04 wenzelm 2010-05-04 proof terms for strip_shyps, based on the version by krauss/schropp with some notable differences: * present type variables are only compared wrt. first component (the atomic type), not the duplicated sort; * extra sorts are grounded towards fixed 'a, potentially with different sorts (the original version with Name.names could cause name clashes with other present variables, too, but this should not be a problem); * deriv_rule_unconditional ensures that proof terms are always maintained independently of the "proofs" flag -- this improves robustness and preserves basic PThm proofs required for extraction attributes, e.g. in theory HOL/Extraction;
2010-05-04 wenzelm 2010-05-04 simplified/unified fundamental operations on types/terms/proofterms -- prefer Same.operation over "option" variant;
2010-05-04 wenzelm 2010-05-04 renamed Proofterm.freezeT to Proofterm.legacy_freezeT (cf. 88756a5a92fc);
2010-03-21 wenzelm 2010-03-21 do not open ML structures;
2010-03-20 wenzelm 2010-03-20 renamed varify/unvarify operations to varify_global/unvarify_global to emphasize that these only work in a global situation;
2010-02-27 wenzelm 2010-02-27 modernized structure Term_Ord;
2009-11-25 haftmann 2009-11-25 normalized uncurry take/drop
2009-11-24 haftmann 2009-11-24 curried take/drop
2009-11-16 wenzelm 2009-11-16 generalized procs for rewrite_proof: allow skeleton; fulfill_norm_proof: always normalize result here, no re-normalization after filling;
2009-11-08 wenzelm 2009-11-08 adapted Theory_Data; tuned;
2009-11-05 wenzelm 2009-11-05 revert fulfill_proof_future tuning (actually a bit slower due to granularity issues?);
2009-11-04 wenzelm 2009-11-04 fulfill_proof_future: tuned important special case of singleton promise;
2009-10-29 wenzelm 2009-10-29 standardized filter/filter_out;

2009-10-01 wenzelm 2009-10-01 back to simple fold_body_thms and fulfill_proof/thm_proof (reverting a900d3cd47cc) -- the cycle check is implicit in the future computation of join_proofs;
2009-09-30 wenzelm 2009-09-30 eliminated redundant parameters;
2009-09-29 wenzelm 2009-09-29 explicit indication of Unsynchronized.ref;
