* Eliminate sprintf in generated python codeSeth R Johnson2022-12-061-3/+3
| | | | | | | Newer clang versions emit warnings in generated code: ``` warning: 'sprintf' is deprecated: This function is provided for compatibility reasons only. Due to security concerns inherent in the design of sprintf(3), it is highly recommended that you use snprintf(3) instead. [-Wdeprecated-declarations] ```
* Use more portable PyUnicode_AsUTF8* methods.Clinton Stimpson2022-11-011-1/+8
| | | | | This supports the use of Py_LIMITED_API and also uses PyUnicode_AsUTF8AndSize if Py_LIMITED_API is set to 3.10 or newer.
* [python] Avoid undefined behaviourOlly Betts2022-10-201-5/+9
| | | | | | | Cast a parameter type explicitly rather than implicitly by casting the function pointer type, as the latter is undefined behaviour. Caught by ubsan.
* Define PY_SSIZE_T_CLEAN only when not defined yetMichal Suchanek2022-10-132-2/+2
| | | | | | | | | | | Users of swig 4.0.2 and python 3.10 will likely define the PY_SSIZE_T_CLEAN macro by hand when relevant because their bindings won't build otherwise. Unconditionally defining PY_SSIZE_T_CLEAN in swig 4.10 will lead to macro redefinition warning. Signed-off-by: Michal Suchanek <msuchanek@suse.de>
* Remove dead conditional codeOlly Betts2022-10-061-6/+0
| | | | | SWIG_POINTER_EXCEPTION has had the value zero since 2006 (it's only still present for backward compatibility).
* [Python] Remove deprecated and apparently useless defarg.swgOlly Betts2022-10-062-38/+0
| | | | | | | | | | | | The only documentation is in the file itself and describes a Python wrapper around the C function defined here, but digging though the git history this Python wrapper doesn't seem to have ever actually been generated by SWIG. This file was also marked as deprecated in 2005. Fixes #2390 Fixes #2391

* | Provide SWIGTYPE MOVE typemaps in swigmove.iWilliam S Fulton2022-09-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | For implementing full move semantics when passing parameters by value. Based on SWIGTYPE && and std::unique_ptr typemaps which implement move semantics. Added for all languages, but untested for: Go, Ocaml, R, Scilab (and unlikely to be fully functional for same reasons as for std::unique_ptr support). Issue #999

| | | | | | | | | | | | | | | | | | Only use the corecrt.h workaround for #2090 when using SWIG_PYTHON_INTERPRETER_NO_DEBUG as the problem seems to only occur when undefining _DEBUG. Also extend workaround for Visual Studio 2019 version 16.10 and 16.11 as per #2174 (_MSC_VER=1929).

* | Performance optimisation for directors for classes passed by valueWilliam S Fulton2022-07-041-1/+1
| | | | | | | | | | | | | | The directorin typemaps in the director methods now use std::move on the input parameter when copying the object from the stack to the heap prior to the callback into the target language, thereby taking advantage of move semantics if available.

| | | | | | | | | | | | | | | | | | | | | | | | | | | Types generated with and without -builtin are not compatible. Mixing them in a common type list leads to crashes. Avoid this by using different capsule names: "type_pointer_capsule" without -builtin and "type_pointer_capsule_builtin" with. See #1684

* | [Python] Fix memory leak.Olly Betts2022-03-071-2/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | SWIG python objects were being freed after the corresponding SWIG module information was destroyed in Python 3, causing leaks when as a result the object destructor could not be invoked. To prevent this misordering, SWIG python objects now obtain a reference to the Python capsule wrapping the module information, so that the module information is correctly destroyed after all SWIG python objects have been freed (and corresponding destructors invoked). Fixes #2154 Fixes #2208

|/ | | | | | This is necessary for regex-like renames (where you can't use the #define trick as is done in many of the %keywordwarn directives). It's now unnecessary to print the "renaming to '`x`'" code explicitly by the kw.swg files.
* [Python] Improve handling of SWIG_Py*Method_NewOlly Betts2022-02-041-0/+8
| | | | | | | | | | | | | | | The SWIG_PyInstanceMethod_New method is no longer added to wrapped classes except when it's actually needed, which is when (!builtin && fastproxy) is true (which it isn't by default). The SWIG_PyStaticMethod_New method is no longer is now similarly gated - previously only (fastproxy) was checked. Finally the C/C++ functions that implement these were always compiled into the module, but now they're only included if (!builtin && fastproxy) is true. Issue noted by vadz in #2190.

* [python] Remove unused bogus fallback macroOlly Betts2022-01-271-1/+0
| | | | | | | | | | | | | This fallback version of PyString_AS_STRING() for Python 3 makes use of PyUnicode_AS_STRING, but I can find no evidence that ever existed in Python - all references I've found are to SWIG or SWIG-generated code. The only uses of PyString_AS_STRING() in SWIG generated code are for Python 2 #if-branches, so this fallback is never used by SWIG. Because it doesn't work it can't be usefully used in user interface files either, so let's remove it to avoid potential user confusion (such as #987).
