Add Swig_obligatory_macros which must be called by each
target language to define SWIG_VERSION correctly
in the generated code, as well as the language specific
macro SWIGXXX where XXX is the target language name.
Drop the #ifdef SWIGXXX that was previously generated -
I can't see the point of this and if users are defining
this macro somehow, then users will need to change this
Closes#1050
Resolve the return type to correctly determine if the type is a pointer or
reference to a director class.
SwigType_refptr_count_return() recently added as a simpler fix is no
longer needed.
The conventional approach of using the "type" rather than "decl" to
analyse the return type is used instead too.
Issue #1823
No meaningful progress to update CFFI to experimental status
has been made since CFFI was disabled in SWIG-4.0.0 as the first
stage to removal. This commit is the final stage to remove it.
See issue #1966 for an attempt at updating CFFI to experimental
status. Anyone wishing for SWIG to support CFFI again might
want to utilise this work.
We had a banner for C, a banner for target languages (parameterised
to allow the comment sequence to be specified) and a special banner
for XML files in scilab.cxx.
The XML variant was only needed because the standard banner contains
`--` for a hyphen, so we now use ` - ` for that instead.
The C banner now calls Swig_banner_target_lang() with a suitable
comment sequence to print the actual banner text.
Until now SWIG quietly ignored such errors unless -Wextra (or -Wall
which implies -Wextra) was passed, but this is unhelpful as it hides
problems. To illustrate this point, enabling this warning by
default revealled a typo in the preproc_defined.i testcase in
SWIG's own testsuite.
If you really don't want to see this warning, you can suppress it
with command line option -w202 or by using this in your interface
file:
%warnfilter(SWIGWARN_PP_EVALUATION);
Both will work with older versions of SWIG too.
Fixes#1465Fixes#2389
Ensure that SWIG_VERSION is defined both at SWIG-time and in the
generated C/C++ wrapper code (it was only defined in the wrapper
for some target languages previously).
SWIGGO and SWIGJAVASCRIPT are now defined in the generated wrappers
to match behaviour for all other target languages.
Stop defining SWIGVERSION in the wrapper. This only happened as a
side-effect of how SWIG_VERSION was defined but was never documented and
is redundant.
The new testcase also checks that SWIG is defined at SWIG-time but not
in the generated wrapper, and that exactly one of a list of
target-language specific macros is defined.
Fixes#1050
In PHP 8.2 zend_operators.h contains inline code which triggers this
warning and our testsuite uses with option and -Werror.
I don't see a good way to only do this within our testsuite, but
disabling it globally like this shouldn't be problematic.
Unfortunately the changes of 26bf86322 (Use SWIG-specific for
non-overloaded synthesized functions too, 2021-11-09) did break some
existing code bases using SWIG as they hardcoded the old wrapper
function names.
So turn this off by default and add a global variable allowing to enable
this, which can be done for a specific language only. This is ugly but,
unfortunately, there is no way to use the Language object from the C
function Swig_MethodToFunction(), so the only alternative would be to
add another parameter to it, but it already has 6 of them, so it
wouldn't really be that much better.
See #2366, #2368, #2370.
Particularly when using virtual inheritance as the pointers weren't
correctly upcast from derived class to base class when stored in the
base's proxy class.
Fixes commented out test code in cpp11_std_unique_ptr_runme
and li_std_auto_ptr_runme D tests.
This OS has been unsupported for over 20 years. We stopped providing
macswig builds more than 20 years ago too:

The required SIOUX library doesn't seem to be available anywhere
now either.
Closes#2323
Avoid using reserved identifiers such as `_DOHINT_H` (fixes#1989),
fix cases where the name doesn't match the filename, and make the naming
more consistent and less likely to collide with include guards in other
headers.
Under %feature("php:type", "compat") we don't generate return type
declaration for virtual methods if directors are enabled for that class.
However if a base class of the class has a method of the same name which
isn't directed this was still getting a return type declaration which
caused PHP to give an error when it tried to load the module.
Now we detect this situation and suppress the base class method's
return type declaration too.
Re-enable testcase director_redefined which now works again (it was
failing under PHP8 due to this issue).
See #2151
Encapsulate the code to generate arginfo in the PHPTypes class.
By itself this should result in no functional changes, but it's
a step towards being able to delay arginfo generation which I
think is necessary to address the incompatible overridden
method problem discussed in #2151.
The XML target language support is not in good shape and is likely to be
removed unless somebody steps up to bring it up to the expected standard
(it fails to even meet the criteria for "Experimental" currently).
Closes#2213
If the same method name is implemented in a parent class then the
subclass can't have more required parameters than that or else we
get a compatibility error when the module is loaded.
The testsuite wasn't catching this problem because it was no longer
trying to load the modules for testcases without _runme.php, because
the mechanism to do that relied on there being a generated .php
wrapper, which we no longer have by default. Fix that to provide a
regression test for this fix.
See #2151
Otherwise can end up with a second PHP exception if the directorout
typemap doesn't accept PHP Null. `SWIG_fail` in this case results
in us returning to PHP which then propagates the pending exception.
This commit fixes a failure in smoketest.php in Xapian's PHP bindings,
but I've not managed to come up with a reproducer which works for
SWIG's testsuite.
I missed that this change breaks cpp_static, which seems to be to do
with handling the combined getter and setter we emit for static
member variables. Reverting while I figure out how to handle that.
