2020-09-22Update copyright header script to support CMake and Python files (#5067)Mathias Preiner
This PR updates the update-copyright.pl script to also update/add copyright headers to CMake specific files. It further fixes a small typo in the header.
2020-06-09Language bindings: Enable catching of exceptions (#2813)Andres Noetzli
Fixes #2810. SWIG relies on throw specifiers to determine which exceptions a method can throw. The wrappers generated by SWIG catch those C++ exceptions and turn them into exceptions for the target language. However, we have removed throw specifiers because they have been deprecated in C++11, so SWIG did not know about any of our exceptions. This commit fixes the issue using the %catches directive, declaring that all methods may throw a CVC4::Exception or a general exception. Note: This means that users of the language bindings will just receive a general CVC4::Exception instead of more specific exceptions like TypeExceptions. Given that we are planning to have a single exception type for the new CVC4 API, this seemed like a natural choice. Additionally, the commit (significantly) simplifies the mapping of C++ to Java exceptions and fixes an issue with Python exceptions not inheriting from BaseException. Finally, the commit adds API examples for Java and Python, which demonstrate catching exceptions, and adds Python examples as tests in our build system.
2020-03-31Rename checkValid/query to checkEntailed. (#4191)Aina Niemetz
This renames api::Solver::checkValidAssuming to checkEntailed and removes api::Solver::checkValid. Internally, SmtEngine::query is renamed to SmtEngine::checkEntailed, and these changes are further propagated to the Result class.

2012-11-26some fixes to language bindings and function visibilityMorgan Deters
2012-10-05Bug-related:Morgan Deters
* ITE removal fixed to be context-dependent (on UserContext). Resolves incrementality bugs 376 and 396 (which had given wrong answers). * some bugfixes for incrementality that Dejan found (fixes bug 394) * fix for bug in SmtEngine::getValue() where definitions weren't respected (partially resolves bug 411, but get-model is still broken). * change status of microwave21.ec.minimized.smt2 (it's actually unsat, but was labeled sat); re-enable it for "make regress" Also: * --check-model doesn't fail if quantified assertions don't simplify away. * fix some examples, and the Java system test, for the disappearance of the BoolExpr class * add copy constructor to array type enumerator (the type enumerator framework requires copy ctors, and the automatically-generated copy ctor was copying pointers that were then deleted, leaving dangling pointers in the copy and causing segfaults) * --dump=assertions now implies --dump=skolems * --dump=assertions:pre-<PASS> and --dump=assertions:post-<PASS> now allow you to dump before/after a particular preprocessing pass. E.g., --dump=assertions:pre-ite-removal or --dump=assertions:post-static-learning. "--dump=assertions" by itself is after all preprocessing, just before CNF conversion. * minor fixes to dumping output * include Model in language bindings Minor refactoring/misc: * fix compiler warning in src/theory/model.cpp * remove unnecessary SmtEngine::printModel(). * mkoptions script doesn't give progress output if stdout isn't a terminal (e.g., if it's written to a log, or piped through less(1), or whatever). * add some type enumerator unit tests * de-emphasize --parse-only and --preprocess-only (they aren't really "common" options) * fix some exception throw() specifications in SmtEngine * minor documentation clarifications
2011-11-22More language bindings work:Morgan Deters
* with a patched SWIG, the ocaml bindings build correctly. ** I will provide my patch to the SWIG dev team. * fixed some class interfaces to play more nicely with SWIG. * php, perl, tcl now work; examples added. * improved binding module building and installation. Also: Stop #defining NULL ((void*) 0). This has been in cvc4_public.h for a long, long time, I forget why I added it in the first place, and it's a very, very bad idea. In C++, certain things are permitted for NULL that aren't permitted for ((void*) 0), like for instance implicit conversion to any pointer type. We didn't see an issue here (until now, when interfacing with SWIG), because GCC is usually pretty smart at working around such a broken #definition of NULL. But that's fragile. New exception-free Command architecture. Previously, some command invocations were wrapped in a try {} catch() {} and printed out an error. This is much more consistent now. Each Command invocation results in a CommandStatus. The status can be "unsupported", "error", or "success" (these are each derived classes, though, not strings, so that they can be easily printed in a language-specific way... e.g., in SMT-LIBv2, they are printed in a manner consistent with the spec, and "success" is not printed if the print-success option is off.) All Command functionality are now no-throw functions, which @cconway reports is a Good Thing for Google (where all C++ exceptions are suspect), and also I think is much cleaner than the old way in this instance. Added an --smtlib2 option that enables an "SMT-LIBv2 compliance mode"---really it just sets a few other options like strictParsing, inputLanguage, and printSuccess. In the future we might put other options into a compliance mode, or we might choose to make it the default.
