On macOS, libz3java.dylib was built without an rpath to find libz3.dylib
in the same directory. When Java loaded the JNI library, the dynamic
linker could not resolve the libz3 dependency, causing
UnsatisfiedLinkError.
Three fixes:
- mk_util.py: add -Wl,-rpath,@loader_path to the macOS JNI link command
- CMakeLists.txt: set MACOSX_RPATH, BUILD_RPATH, INSTALL_RPATH for
z3java target; remove duplicate headerpad block
- update_api.py: improve Native.java error message to show the root
cause from both load attempts instead of only the fallback error

New methods:
- Expr.getNumeralDouble(): retrieve any numeral as a double
- IntNum.getUint(): extract numeral as unsigned 32-bit value
- IntNum.getUint64(): extract numeral as unsigned 64-bit value
- RatNum.getSmall(): numerator/denominator as int64 pair
- RatNum.getRationalInt64(): numerator/denominator (returns null on overflow)
Each is a thin wrapper around the existing Native binding.
Added examples to JavaExample.java covering all new methods.
* add Expr.isGround() to Java API
Expose Z3_is_ground as a public method on Expr. Returns true when the
expression contains no free variables.
* add Expr.isLambda() to Java API
Expose Z3_is_lambda as a public method on Expr. Returns true when the
expression is a lambda quantifier.
* add AST.getDepth() to Java API
Expose Z3_get_depth as a public method on AST. Returns the maximum
number of nodes on any path from root to leaf.
* add ArraySort.getArity() to Java API
Expose Z3_get_array_arity as a public method on ArraySort. Returns
the number of dimensions of a multi-dimensional array sort.
* add DatatypeSort.isRecursive() to Java API
Expose Z3_is_recursive_datatype_sort as a public method on
DatatypeSort. Returns true when the datatype refers to itself.
* add FPExpr.isNumeral() to Java API
Expose Z3_fpa_is_numeral as a public method on FPExpr. Returns true
when the expression is a concrete floating-point value.
* add isGroundExample test to JavaExample
Test Expr.isGround() on constants, variables, and compound
expressions.
* add astDepthExample test to JavaExample
Test AST.getDepth() on leaf nodes and nested expressions to verify
the depth computation.
* add arrayArityExample test to JavaExample
Test ArraySort.getArity() on single-domain and multi-domain array
sorts.
* add recursiveDatatypeExample test to JavaExample
Test DatatypeSort.isRecursive() on a recursive list datatype and a
non-recursive pair datatype.
* add fpNumeralExample test to JavaExample
Test FPExpr.isNumeral() on a floating point constant and a symbolic
variable.
* add isLambdaExample test to JavaExample
Test Expr.isLambda() on a lambda expression and a plain variable.
This fixes the install_name_tool issue on macOS where the tool fails
with "larger updated load commands do not fit". The linker flag
-Wl,-headerpad_max_install_names ensures sufficient header padding
in the Mach-O binary for install_name_tool to modify install names.
Changes made:
- CMake: Added flag to libz3, z3java, z3jl shared libraries on Darwin
- Python build: Changed flag from ML-only to all macOS builds
- OCaml CMake: Added flag to OCaml stublib build on APPLE

* Add TypeVarSort.java to CMakeLists.txt for Java bindings
The CMake build was failing because TypeVarSort.java was not included in the Z3_JAVA_JAR_SOURCE_FILES list in src/api/java/CMakeLists.txt. Added it in alphabetical order between TupleSort.java and UninterpretedSort.java.

Co-authored-by: NikolajBjorner <3085284+NikolajBjorner@users.noreply.github.com>
* Update language bindings for parametric datatype sort API
- Python: Updated DatatypeSort() to accept optional params list
- OCaml: Added mk_sort_ref_p/mk_sort_ref_ps for parametric datatypes
- .NET: Added MkDatatypeSortRef() methods with optional params

* Fix .NET build error - rename params to parameters
The 'params' keyword is reserved in C#, causing compilation errors.
Renamed parameter from 'params' to 'parameters' in MkDatatypeSortRef methods.

* Add unit test for parametric datatypes
Added test_parametric_datatype.cpp to demonstrate polymorphic datatypes.
The test creates two concrete instantiations of a generic pair concept:
- pair_int_real with fields (first:Int, second:Real)
- pair_real_int with fields (first:Real, second:Int)
Then verifies that accessors work correctly and type checking is enforced.

* Implement polymorphic type variables support for parametric datatypes
- Modified datatype_decl_plugin to allow type variables as parameters
- Updated mk_datatype_decl to extract type variables from field sorts
- Type variables are collected in order of first appearance
- Revised unit test to use Z3_mk_type_variable for polymorphic datatypes
- Test creates pair datatype with type variables alpha and beta
- Successfully instantiates with concrete types (pair Int Real) and (pair Real Int)
- Verifies accessor types match and equality terms are well-typed
- All tests pass

* Add Z3_mk_polymorphic_datatype API and refactor datatype creation
- Added new API Z3_mk_polymorphic_datatype to z3_api.h
- Renamed static mk_datatype_decl to api_datatype_decl in api_datatype.cpp
- Modified api_datatype_decl to accept explicit type parameters
- Updated all callers to use renamed function
- Added test_polymorphic_datatype_api demonstrating new API usage
- Both tests pass successfully

* Remove type variable collection logic from constructors
Removed the logic for collecting type variables from field sorts based on constructors.
* Update comments on parameter handling in api_datatype.cpp
Clarify usage of parameters in API documentation.
* Fix OCaml build error - use list instead of array for mk_datatype_sort
Changed mk_sort_ref to pass empty list [] instead of empty array [||].
Changed mk_sort_ref_p to pass params list directly instead of converting to array.
Z3native.mk_datatype_sort expects a list, not an array.

* Add polymorphic datatype example to C++ examples
Added polymorphic_datatype_example() demonstrating:
- Creating type variables alpha and beta with Z3_mk_type_variable
- Defining parametric Pair datatype with fields of type alpha and beta
- Instantiating with concrete types (Pair Int Real) and (Pair Real Int)
- Getting constructors and accessors from instantiated datatypes
- Creating constants and expressions using the polymorphic types
- Verifying type correctness with equality (= (first p1) (second p2))

* Reworked phantom reference handling.
- Replaced IDecRefQueue with a new Z3ReferenceQueue class
- Z3ReferenceQueue manages custom subclasses of phantom references in a doubly-linked list
- Replaced all subclasses of IDecRefQueue with subclasses of Z3ReferenceQueue.Reference. These custom reference classes are embedded in the class they reference count.
- Context now owns a single Z3ReferenceQueue for all types of references.
* Made Statistics.Entry a static subclass
* Made Context.close idempotent (as recommended)
* Update CMakeLists.txt for building the Java API.
* Updated CMakeLists.txt again.
* Use correct SuppressWarning annotation to silence the compiler
* Formatting
* Fixed decide callback for Java user propagators
* Java User Prop:
- Added return value to conflict
- Added consequence method
- Added missing access modifier to decideWrapper
* Removed type parameters of expressions in UserPropagatorBase
* Renamed propagateConflict to propagateConsequence
`FindPythonInterp` has been deprecated for a long time and is more
verbal about that deprecation now.
The build system no longer uses `PYTHON_EXECUTABLE` but instead uses
`Python3_EXECUTABLE`.
