more explicit errors to inform users about problems related to SMT solvers; fall back to remote SMT solver (if local version does not exist); extend the Z3 proof parser to accommodate for slight changes introduced by Z3 2.18

more explicit exit due to failed etc/settings -- normally return code 0=true and 1=false could be tolerated, but bash syntax errors also return 1;

eliminated somewhat obsolete warning -- former "$HOME/Isabelle" vs. "$HOME/isabelle" no longer exist;

tuned;

more pretty set comprehension sugar

merged

adjusting HOL-Mutabelle to changes in quickcheck

quickcheck can be invoked with its internal timelimit or without

quickcheck invokes TimeLimit.timeLimit only in one separate function

added option to Mirabelle Sledgehammer

merged

reverted cs. 0a3fa8fbcdc5 -- motivation is unreconstructable, produces confusion in user space

tuning

fix handling of "fequal" in generated ATP problems -- the bug was visible if "explicit_apply" was on and "singleton_conv" is one of the facts being translated, as it resulted in an arity error in the ATP (e.g., E)

fix path to etc/settings and etc/components in doc

run all provers in blocking mode, even if a proof was already found -- this behavior is less confusing to the user

remove pointless clutter

make minimizer verbose

tuning

automatically minimize Z3-as-an-ATP proofs (cf. CVC3 and Yices)

renamed field

added "Z3 as an ATP" support to Sledgehammer locally

remove Z3 wrapper script, which is no longer necessary now that the SMT module generates SMT-LIB compliant files

added experimental "remote_z3_atp", Sutcliffe's TPTP-syntax-aware wrapper for Z3 -- allows to do head-to-head comparison of Sledgehammer's ATP translation and of Sascha's SMT translation

tuned scope of Multithreading.interrupted vs. Multithreading.with_attributes;

merged

changing auto-quickcheck to be considered a non-interactive invocation of quickcheck

discontinued obsolete lib/scripts/polyml-platform;

clarified comment -- ancienct PG 3.7.x is still in use;

discontinued obsolete alias HOL.thy for @{theory HOL} in ML;

prefer polyml-5.2.1 over odd polyml-5.3.0-old;

some shuffling of isatest settings, to ensure coverage of polyml-5.2.1, polyml-5.3.0, polyml-5.4.0, polyml-5.4.1 (SVN), smlnj/110.72;

reverted slightly odd eb5900951702: isatest-doc should work again due to 4b08499b3db1 (polyml-5.3.0 supports proper TimeLimit, as required for HOL-Nitpick-Examples);

merged

available_provers ~> supported_provers (for clarity)

sort E weights

added support for bleeding-edge E weighting function "SymOffsetsWeight"

transformed lie into truth

enable SMT weights and triggers, since they lead to slight improvements according to the Judgment Day suite

improving sum type and option type term constructions for correct presentation in Smallcheck

Explicitly build HOLCF and ZF images. They are not part of the release any more.

added termination lemmas

improving term construction of product types in Smallcheck which enables correct presentation of counterexamples

discontinued support for Poly/ML 5.2, which was the last version without proper multithreading and TimeLimit implementation;

tuned headers;

updated to polyml-5.3.0, which is presently known as the most robust version;

explicit Multithreading.interrupted to ensure that interrupts stay within the boundaries of managed evaluation blocks;

always test/clear Multithreading.interrupted, indepently of thread attributes; tuned;

added Multithreading.interrupted (cf. java.lang.Thread.interrupted);

more robust TimeLimit: make double sure that watchdog has terminated and interrupts received during uninterruptible state are propagated (NB: Thread.testInterrupt requires InterruptSynch in Poly/ML 5.4.0 or earlier);

more tracing information via Par_List.map_name;

clarified bootstrapping of structure TimeLimit;

more scalable collections of tasks, notably for totality of known group members; tuned;

tuned signature; tuned;

merged

prefer p2e before e2p; use measure_unique_Int_stable_vimage;

add auto support for AE_mp

add borel_fubini_integrable; remove unused bijectivity rules for measureable functions

parallelization of nested Isar proofs is subject to Goal.parallel_proofs_threshold;

Task_Queue.update_timing: more precise treatment of interruptibility; Task_Queue.waiting: potentially expensive wait dependencies are subject to trace flag;
