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.

Fixes #2846. One of the challenges of the Java bindings is that the
garbage collector can delete unused objects at any time in any order.
This is an issue with CVC4's API because we require all `Expr`s to be
deleted before the corresponding `ExprManager`. In the past, we were
using `NewGlobalRef`/`DeleteGlobalRef` on the wrapper object of
`ExprManager`. The problem is that we can have multiple instances of the
wrapper that internally all refer to the same `ExprManager`. This commit
implements a different approach where the Java wrappers hold an explicit
reference to the `ExprManager`. The commit also removes some unused or
unimportant API bits from the bindings.

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.

updated old-style copyrights in the examples
|
|
* 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
|
|
* change name of JNI library to "libcvc4jni", which works better with Java's
System.loadLibrary().
