Order of evaluation of C++ function arguments is not defined, and if
lua_rawlen() was called before lua_tostring() then it would return 0
(because the value was still a number) and an empty string would be
passed.
The same issue affects std::string_view too, but that's not been in
a release yet.
The new testcases fail without the fix with GCC 12.2 on x86-64 Linux.
The strings from the Octave array are returned in a temporary
std::string object so we need to make a copy of them or else the
final string ends up replicated as all elements.
Unfortunately argcargvtest.i was only checking the final element's
value, so fix it to test both the elements as a regression test for
this, and to catch any similar issues with other target languages.
Arrange that destructors of local C++ objects in the wrapper function
get run on SWIG_fail (which calls lua_error() which calls longjmp()).
We achieve this by putting almost everything in the function in its
own block, and end that right before lua_error() at which point those
destructors will get called.
Go, Guile, Racket, Scilab: Add throws typemaps for std::string so that
thrown string exception messages can be seen.
Test all language for std::string throws typemaps
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
Support running testcases conditional on the compiler supporting
a each language version, like we already handle C++11.
Currently no testcases are actually run in this way for these
newer language versions.
Move HAVE_CXX11 into makefiles so that running test-suite
from top level directory or in the language's test-suite directory
is consistent. For example, running 'make check-java-test-suite'
behaves the same as 'cd Examples/test-suite/java && make check'.
SWIGJSC_ValueIsArray could be implemented by JSValueIsArray in later
versions of Javascript webkit, similar fix to previous commits for v8.
Enhance testing of OUTPUT typemaps to test more than one output.
Found via `codespell -q 3 -L "uint,bae,objext,cmo,goin,struc,ois,upto"`
whitespaces were unintentionally fixed due to my editors settings.
Rebased patch #1327
Since Lua 5.3 the "%c" format character in lua_pushfstring will produce
the string "<\XXX>" (XXX being a decimal code sequence) when
given unprintable characters.
Use lua_pushlstring instead to reproduce the old behavior.
* Renamed SWIG_Lua_equal to SWIG_Lua_class_equal
* If class has no __eq implemented, then default __eq is provided.
Default __eq compares actual pointers stored inside Lua userdata
- Examples/Makefile.in rules use SRCDIR as the relative source directory
- ./config.status replicates Examples/ source directory tree in build
directory, and copies each Makefile to build directory, prefixed with
a header which sets SRCDIR to source directory
- Examples/test-suite/.../Makefile.in set SRCDIR from Autoconf-set srcdir
- Examples/test-suite/errors/Makefile.in needs to filter out source
directory from SWIG error messages
- Lua: embedded interpreters are passed location of run-time test
- Python: copy run-time scripts to build directory because of 2to3
conversion; import_packages example copies __init__.py from source
directory; test-suite sets SCRIPTDIR to location of run-time tests
- Javascript: binding.gyp renamed to binding.gyp.in so that $srcdir
can be substituted with SRCDIR; removed './' from require() statements
so that NODE_PATH can be used to point Node.js to build directory
- some of the %.clean rules in the test-suite Makefiles were using a single tab
as an empty rule, dangerous! I've replaced these with the safer '@exit 0'.
