SWIG_SetPointerZval() requires the zval structure passed to be
initialised (so it can handle the constructor case where the zval is
already initialised as a PHP object.
I couldn't think of a suitable regression test for this, but it fixes 2
issues detected by running director_basic under valgrind.
The typemaps for long long and unsigned long long didn't handle a
string input correctly, and long_long_runme.php had a flawed test
in this case.
Fixes#2155
It seems instanceof_function_ex() isn't a viable option for PHP 7.3 and
earlier - the implementation is strangely wrong.
So let's just provide a compatibility implementation which does what
zend_class_implements_interface() does in 8.x and use that for all 7.x
so there are fewer variants to worry about testing.
The sense of parameter 3 of instanceof_function_ex() appears to have
changed in PHP 7.4 and we need to pass 0 for older versions and 1 for
PHP 7.4. Words fail me.
Since the switch to wrapping classes using PHP's C API, we now
internally need to be able to tell if a PHP object is of or derived
from a class that is wrapped by SWIG so we know if we can offset the
zend_object pointer to get to the swig_object_wrapper. If we try to
do this to an object which isn't wrapped by SWIG then we invoke C/C++
undefined behaviour (and typically get a segmentation fault).
This check is implemented by having a SWIG\wrapped empty interface which
we make all SWIG-wrapped classes implement simply so we can test for it
to detect such classes.
Fixes#2125
As discussed and agreed in #1629, it's become hard to test with Perl
5.6 or earlier, such old versions are no longer in active use, and
4.1.0 is an appropriate time to make such a change.
I've dropped the compatibility code that was obvious to me, but there's
probably more that can be cleaned up now.
Fix access to C++ static member functions using Python class
staticmethod syntax, such as Klass.memberfunction instead of
Klass_memberfunction, when using -fastproxy and -builtin in
combination with %callback.
The docstring containing the callback pointers were not being patched
during module initialisation.
Accept keyword arguments accessing C++ static member functions when
using -builtin and kwargs feature and Python class staticmethod syntax.
The missing keyword argument support was only when using the
class staticmethod syntax, not when using the flat static method
syntax.
Use Python class staticmethod syntax to access C++ static member functions,
such as Klass.memberfunction, instead of Klass_memberfunction.
Examples and test-suite changes in preparation for issue #2137.
Unfortunately Travis CI can't be used for building open source projects
any longer in practice, as extra credits must be manually requested
every time from Travis support, which is just infeasible, as this would
need to be done every couple of days if not more often, and support
reply time is anything from a couple of days to more than a month.
So stop even trying to use it, as it doesn't work anyhow, and switch to
using GitHub Actions only.
Closes#2067
We've dropped support for the old V8 versions which lacked version
macros, and SWIG_V8_VERSION now gets automatically defined by
Lib/javascript/v8/javascriptruntime.swg which will #undef it first if
it's already defined.
With C++ comments changed to C comments, these are now identical to
the two cases just above, aside from the `2` suffix on the names.
Follow-on for #2027.
