The old Node.js versions don't treat v8::Handle and v8::Local as
the same types, and the latest versions (v12 and newer) have
removed v8::Handle at all.
This patch introduces the following macros that use v8::Handle or
v8::Local depending on the selected Node.js version:
- SWIGV8_ARRAY
- SWIGV8_FUNCTION_TEMPLATE
- SWIGV8_OBJECT
- SWIGV8_OBJECT_TEMPLATE
- SWIGV8_VALUE
* abstract-conversion-operators:
Add test cases for abstract user-defined conversion operators
Recognize C++ conversion operators with trailing '= 0' as abstract
When wrapping STL containers, remove a shared_ptr reference count
increment when an upcast is needed when checking type conversion
in traits_check::check.
This test code tests the upcast code:
swig_assert_equal_simple(-1, base_num2([Derived(7)]))
Although there is no explicit memory leak fix test, it does at least run the code.
Handling of None needs fixing in Python (it is working in Ruby)
Note that the Ruby implementation has a partial template specialization
for shared_ptr, whereas the Python implementation is in the generic
code!
Issue #1512
* 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
Due to confusion in build_combined_docstring(), we could call
DohDelete() on the "feature:docstring" string, which resulted in a crash
when trying to use it later.
Fix this and simplify the code at the same time by ensuring that we
always use a copy of "feature:docstring" if it's not empty or don't use
it at all if it's empty -- like this we don't have to check for its
length each time before using it.
Closes#1648.
* RMemberListTrialSimplify2019:
ENH R abstract_access_runme
ENH R accessor processing test
Removed some remaining commented sections
moved registration routine and use swig_name_get
calling Swig_name_setget
Used Swig_name_register so that Swig_name_wrapper produces the correct name without a separate replace call.
Removed last instance of using Strcmp to check for a set/get method. Replaced with check for flag.
Alternative version of using memberlist processing. This clarifies the logic within OutputMemberReferenceMethod by filtering the lists into classes, rather than doing it internally. Code isn't any shorter.
commenting out unused code
first pass at removing string comparisons for set/get methods
trial changing member list processing
