Releases · ultimate-pa/ultimate

Ultimate.py wrapper script cli arguments:

--data <directory> can be used to specify the data directory (location for temporary files) (close #115)
--config <directory> can be used to specify the directory in which settings (.epf) and toolchain (.xml) files are stored (close #114)
--witness-dir <dir> and --witness-name <string> allows you to specify to where the correctness or violation witness is written (close #116)
all cli arguments are now non-positional
init()-clause is now extracted from .prp files and passed as parameter to Ultimate (close #117)
LTL formulas are extracted from .prp files and converted to Ultimate input files (.ltl) if necessary (close #118)

BlockEncoding

AutomataLib

added a new mode "DYNAMIC" (default) that uses the complete test based on heuristics

Error messages and log messages

Statistics

optionally report a BenchmarkResult for every round
show statistics information on timeout
also use .csv data from StatisticsData.class
improved statistics for Automata Minimization, FullMultipebble
new statistics AutomataOperationStatistics, ConstraintsSolvingTime, ConstraintsConstructionTime, ProgramLocsLbe
MotzkinTransformations, DAGTreeSize separately for normal and under and/or overapproximation constraints
number of Motzkincoefficients
separate ProgramSize into ProgramSizeConjuncts and ProgramSizeDisjuncts

Misc

new plugin InvariantSynthesis
now supporting analysis of hybrid systems with SpaceExParser
new transformula transformation for modulo operations: ModuloNeighborTransformation
PathPrograms can be extracted from ICFG and written to .bpl file
Hoare-Triple-Checker based on abstract interpretation implemented (see #109)
added support for float macros fpclassify and isnormal from math.h
added generalization of counter examples in TreeAutomizer
Updated website / webinterface
Updated various default settings

transformula transformation RemoveNegation makes "best effort" when removing negations instead of crashing
fix ltlautomizer bug (always trivially satisfied)
fix webinterface deployment
fix "always debug logging in gui" bug
plugin implementing multiple extension points is listed only once (closes #70)
fix bug in IcfgLocationIterator which lead to duplicate states in stream if an initial node can be visited multiple times (closes #130), same for IcfgEdgeIterator
fix various memory leaks in test framework that occurred after introduction of non-static handling of AfterClass directives (explicitly freeing pointers) (see #132)
fix incomplete Buchi language equivalence check was unsound
various fixes for PMaxSAT and other automata operations
fix size computation in PartitionBackedSetOfPairs

Project ICFG of the future

replaced dependencies to BoogieIcfgLocation, Call, Return, Codeblock with IcfgLocation, IAction, IICfgTransition counterparts all over the place
fix Kojak compatibility with IIcfg
remove IType from BoogieVar
cleanup RankVarConstructor
remove methods for construction of auxiliary variables in Boogie to SMT conversion
add method for construction of global program variables in ProgramVarUtils
refactoring: construction of auxiliary rankvars does not modify original symbol table

Testing

enable non-static after class methods in JUnit to get rid of static incremental logs and summaries (prevents conflicts during parallel test execution because of back references to core/service instances)
added testsuite describing Taipan vs Automizer differences in SVCOMP17 (based on Marius' script, closes #133)
added LTLAutomizer regression test suite (closes #110)
added IFailedAnalysisResult to group failure results
added NoErrorTestResultDecider that fails if we provide no analysis result for any reason except timeout
clearer regex handling in regression test suite (having include and exclude regexes that behave as expected) (73a223f)

Misc

ILocation is an annotation, ILocation#getOrigin is removed
introduced infrastructure for merging annotations (especially locations), merge locations during block encoding
allow IController to access IToolchainStorage before toolchain execution via IController#prerun callback
new feature for preferences: register preference layers (via IUltimateServiceProvider#registerPreferenceLayer(Class<?> creator, String... pluginIds)) that allow you to temporarily overwrite preferences
introduced TransforumlaTransformationResult to represent overapproximations during transformula transformation (closes #127)
refactoring of IStateFactory and cleanup of AutomataLibrary
fixed most of the Sonar issues for TreeAutomizer
added external binaries (z3, mathsat, cvc4, ...) to repository in default/adds directory and use them during deployment (necessary for Distress)

Hoare-Triple-Checker based on abstract interpretation has still some bugs (see #109)
README and Website usage instructions still outdated (see #135)
