and newer (and some missing ones from 5.3). Reserved PHP constants
names are now checked against enum values and constants, instead
of against function and method names. Built-in PHP function names
no longer match methods added by %extend. Functions and methods
named '__sleep', '__wakeup', 'not', 'parent', or 'virtual' are no
longer needlessly renamed.
I managed to trace a very nasty Python interpreter segfault to an
allocation failure here. Adding this after the tp_new call:
if (PyErr_Occurred()) {
PyErr_Print();
}
results in output of 'TypeError: object() takes no parameters', followed
by a segfault that takes down the Python interpeter.
The 'object' constructor doesn't seem to be suitable for instantiating
SWIG shadow instances in this way, so simply use the constructor
function in the PyTypeObject 'tp_new' slot of data->newargs.
The 'if (inst)' check after this doesn't hurt in as much as it prevented
a segfault immediately after this failed allocation, but it doesn't help
much since the null pointer dereference will probably happen sooner or
later anyway.

Guile: make scm to string conversion work with non-ascii strings
Guile: illustrate bug in non-ascii string handling
clang++ using -stdlib=libc++ defines const_reference as a class,
to map boolean vectors onto a bit set. Because swig does
not "see" the type as "const &" it generates incorrect code for this case,
generating a declaration like:
const_reference result;
When const_reference is a typedef to 'bool' as is the case with stdlibc++
this works. When this is actually a constant reference, this is clearly
invalid since it is not initialized. For libc++, this is a class
which cannot be default constructed, resulting in an error. The fix
is to explicitly define the various accessor extensions as having a
bool return type for this specialization.
Generated code does not include <string>, which is referenced in templates.
Clang may be incorrectly or aggresively instantiating some template.
E.g.,
import_stl_b_wrap.cxx:3199:51: error: implicit instantiation of undefined template 'std::__1::basic_string<char, std::__1::char_traits<char>
It was previously possible to assign "hello" to a variable backed by char[5]
storage in C, and the array contained the correct character data but without
the trailing NUL, which was unexpected in C.
This is not allowed any more, only "helo" can fit into a char[5] now and
anything else fails the type check, just as it already happened for the longer
strings before.
Closes#122
Use the usual C rule for NUL-terminated strings instead of discarding all the
trailing NUL characters.
This was unexpected (as buffers in C code are not necessarily always padded
with NULs to their full length) and also inconsistent among languages as this
was only done for those of them using typemaps/strings.swg but not for C# or
Java, for example, which terminated the string at the first NUL even before
this change.
Notice that this patch couldn't use strlen() or wcslen() with possibly not
NUL-terminated strings, so we had to add [our own equivalents of] strnlen()
and wcsnlen() and use them instead. This required adding yet another parameter
to string typemap macros, so update the example using them accordingly too.
