dropped obsolete FIXMEs

merged, resolving spurious conflicts and giving up Reflected_Multivariate_Polynomial.thy from ab5d2d81f9fb;

eliminated global prems

modernized specification; curried

recdef -> fun; curried

recdef -> fun; curried

strengthened polymul.induct

dropped stupid name

removed duplicate declarations

recdef -> function

tuned proofs -- eliminated prems;

merged

adjust example

document new "preconstr" option

more work on "fix_datatype_vals" optimization (renamed "preconstruct")

more work on "fix_datatype_vals"

first steps in implementing "fix_datatype_vals" optimization

better fudge factors for CVC3 and Yices based on Judgment Day

exit code 127 can mean many things -- not just (and probably not) Perl missing

modernized specifications;

rename Nitpick's (internal) auxiliary lemmas

updated docs w.r.t. "nitpick_unfold" attribute

improve optimization

updated docs

tweaked Nitpick based on C++ memory model example

renamed "nitpick\_def" to "nitpick_unfold" to reflect its new semantics

always unfold constant defitions marked with "nitpick_def" -- to prevent unfolding, there's already "nitpick_simp"

give more weight to Frees than to Consts in relevance filter

don't distinguish between "fixes" and other free variables -- this confuses users

added a timeout around SMT preprocessing (notably monomorphization)

comments to find fudge factors easily

added test cases with quantifier occurring in first-order term positions

wrap occurrences of quantifiers in first-order terms (i.e., outside first-order formulas) in If-expressions

dropped redundancy

merged

added is_IAbs; tuned brackets and comments

more idiomatic printing of let cascades and type variable constraints

merged

modernized specifications;

modernized specifications;

more precise headers;

less verbose tracing;

standardized headers;

modernized specifications;

gracious timeout in "blocking" mode

make Nitpick's timeout mechanism somewhat more reliable/friendly; avoid producing warnings when invoked in "auto" mode

better fudge factors for Sledgehammer

adjust fudge factors

extended ATP problem syntax to support other applications than Sledgehammer, e.g. experiments with ATPs

export more functionality of Sledgehammer to applications (for experiments)

export useful function (needed in a Sledgehammer-related experiment)

make experimental "Z3 ATP" work on Linux as well

adjusted fudge factors (based on Judgment Day runs)

generalized termination lemmas

strengthened induction rule; clarified some proofs

limit the number of generated SMT monomorphization instances (in addition to the existing monomorphization limit which does not prevent seemingly infinite loops); updated SMT certificate

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;

Lazy.force_result: more standard treatment of interruptibility, potentially addressing races of exceptions vs. interrupts;

thm_proof: visible fulfill_body only, without joining nested thms -- retain proof irrelevance, which is important for parallel performance;

tuned comments;

clarified Proofterm.proofs_enabled;
