When wrapping STL containers, remove a shared_ptr reference count
increment when an upcast is needed when checking type conversion
in traits_check::check.
* master-fix-vector-shared_ptr:
fixing memleak of shared_ptr objects in python with creating a [wrapped] vector<shared_ptr<Foo>> from a list of shared_ptr<Bar> where Bar is derived from Foo.
If python_append.i is modified to use:
__slots__ = []
instead of
__slots__ = ["this"]
then this additional error checking prevents a crash and shows a stack trace and error:
AttributeError: 'ForSlots' object has no attribute 'this'
Related to issue #1674
Don't attempt to use the class's __dict__ for setting 'this' when
a user has extended a class with:
__slots__ = ['this'].
Was segfaulting. Now we fall back to a simple PyObject_SetAttr if the
usual approach to setting 'this' in __dict__ does not work.
Closes#1673Closes#1674
There is a possible memory leak in case the SWIG_exception_fail macro
is called. The problem is related to its definition that call the
function Rf_warning. This function (as well as Rf_error) involves
a longjmp over C++ destructors on the stack. Thus, all the objects
allocated on the heap are not freed.
Closes#914
Instead of silenty ignoring them, now a "TypeError: f() takes no keyword arguments"
exception is thrown if keyword arguments are used. Hence constructors and normal
methods/functions behave in the same way.
Closes issue #1595
The macros for casting function pointers are now fully described and also
clarify why the macros act transparently for C even before Ruby 2.7.
In addition, an "if (CPlusPlus)" was removed in the code generator for
global variables in order to keep the distinction between C and C++ in
one place, which is at the definition of said macros.
This commit fixes the signatures of various callback methods
and cleans up the macro definitions used for casting callbacks.
Note that the transparent version of the macro RUBY_METHOD_FUNC
is currently masked behind RUBY_DEVEL, see commit
1d91feaf13
In order to still support strict signature checking and prevent
nasty deprecation warnings, the use of RUBY_METHOD_FUNC had to
be replaced with VALUEFUNC.
The type long may be 4 bytes but swig_this() must return the address of
the object as an integer. Using size_t ensures that the return type can
store a pointer.
This is actually a fix to some functionality that I submitted many years ago. :) At the time I set the string conversion to output the userdata address, but since that points to an internal SWIG structure, it's way more useful to the user to point to the actual memory being wrapped in that userdata.
For such types, the generated proxy class inherited from
java.util.AbstractSet<BoxedType<T>> (where BoxedType<T> is "Integer",
for example, when T is "int"), but defined an overloaded add() taking T,
instead of overriding the base class virtual add() taking BoxedType<T>,
resulting in an exception being thrown whenever add() was called during
run-time.
Extend Java unit test to bring it to parity with C# one added in the
previous commit.
See #1568.
Notably make them work for primitive types, such as "int".
Doing this requires using "object" instead of the actual C# type of the
variable to store the current value in the iterator, as we don't
currently have a "csnullabletype" typemap that would expand to "T" for
nullable types and "T?" for the other ones. This is a bit ugly, but it
shouldn't matter much for the generated code and is already done in
std::vector<> typemaps.
Also add a simple unit test verifying the basic functionality for such
vectors.
Closes#1568.
This is just a mistake remaining from generalizing the old
string-specific typemap to any type.
Fix it now and update a unit test to test for sets of objects other than
strings.
Default marshalling for bool[] now uses 1-byte entries in the array, to
ensure array contents is as expected in C++.
When running under mono csharp_lib_arrays_bool testcase will fail
due to an apparent bug in mono. Works correctly under Microsoft's
runtime. See https://github.com/mono/mono/issues/15592
