Exit() is a wrapper for exit() by default, but SetExitHandler() allows
specifying a function to call instead.
This means that failures within DOH (e.g. Malloc() failing due to lack
of memory) will now perform cleanup such as removing output files.
This commit also cleans up exit statuses so SWIG should now reliably
exit with status 0 if the run was successful and status 1 if there was
an error (or a warning and -Werror was in effect).
Previously in some situations SWIG would try to exit with the status set
to the number of errors encountered, but that's problematic - for
example if there were 256 errors this would result in exit status 0 on
most platforms. Also some error statuses have special meanings e.g.
those defined by <sysexits.h>.
Also SWIG/Javascript tried to exit with status -1 in a few places (which
typically results in exit status 255).
These were officially deprecated in 2001, and attempts to use them have
resulted in a warning (including a pointer to what to update them to)
for most if not all of that time.
Fixes#1984
- Since (at least) Octave 5.1.0, the Octave error() function now raises a C++
exception, which if uncaught immediately exits a SWIG wrapper function,
bypassing any cleanup code that may appear after a "fail:" label.
- This patch adds a "try { ... } catch(...) { }" block around the contents of
SWIG wrapper functions to first execute the cleanup code before rethrowing any
exception raised.
- It is backward compatible with earlier versions of Octave where error() does
not raise an exception, which will still branch to the "fail:" block to
execute cleanup code if an error is encountered.
Backport changes to Python version of make_autodocParmList() to Ruby and
Octave modules, which use similar code.
In particular, this improves handling of parameters clashing with the
language keywords/reserved words for these languages as well.
The -cppcast option is still turned on by default. The -nocppcast option
to turn off the use of c++ casts (const_cast, static_cast etc) has been
removed. However, defining SWIG_NO_CPLUSPLUS_CAST will still generate C casts
instead of C++ casts for C++ wrappers.
This a revert of commit fc79264a48:
"Revert "Remove -cppcast and -nocppcast command line options""
The Scilab and Javascript casting problems are now fixed, so -cppcast
is now switched on as default.

- Fixes generation of director method declarations containing C++11 ref-qualifiers.
- Fixes generation of director method declarations returning more complex types such
as const ref pointers.
- Rewrite Swig_method_call to use more up to date code in the core.
The directorin typemaps will now generate a temporary variable
(specified after the type), such as:
%typemap(directorin) MyType (MyType *temp) { ... use temp ... }
The shared_ptr director typemaps have been fixed for use in functions
that take more than one parameter.
- Restructure runtime code into declarations, function
and class definitions, and initialisation code
- Rename internal functions/types to follow SWIG_Octave...
or SwigOct... naming styles
- Style/comment/whitespace cleanups
- Used "astyle -A10 -s2 -N -p -H -U -k1" for style cleanup
- Replaced NewString("") with NewStringEmpty()
- Used 'w' instead of 'f' for Wrapper() objects
Error checking for this combination implemented as well as correcting
Octave
Also refactor, replacing CPlusPlusOut variable with cparse_cplusplusout
for an implementation which more closely resembles cparse_cplusplus which
is also required in both .c and .cxx files.

CPlusPlusOut mode for Octave
nested class illustration
fixed "Abstract" flag for nested classes added an example enabled anonymous nested structs runtime test
porting
warnings disabled
porting fixes
java runtime tests ported
nested class closing bracket offset fixed
removed double nested template (not supported by %template parsing)
template_nested test extended
parent field made public
property access fixed
replaced tabs with spaces
warning W-reorder
deprecated warnings removed, derived_nested runtime test added
optimized string indenting
Nested classes indenting
nested classes docs
fixed the order in which flattened inner classes are added after the outer
Private nested classes were getting into the type table.
Java getProxyName() fix for nested classes fixes the case when nested classes is forward declared
Fix for a case when a nested class inherits from the same base as the outer. (Base class constructor declaration is found first in this case)
merge fix
nested C struct first immediate declaration incorrectly renamed sample fixed
tests updated to reflect nested classes support
Java nested classes support (1)
flattening should remove the link to the outer class
access mode correctly set/restored for nested classes
nested templates should be skipped while flattening (template nodes themselves, not expanded versions) also non-public nested classes should be ignored
If nested classes are not supported, default behaviour is flattening, not ignoring flag "nested" is preserved, so, the nested classes can be ignored by user
nested workaround test updated
template instantiated within a class is marked as nested for ignoring purposes
%ignore not applied to the nested classed, because "nested" flag is set too late
typedef name takes precedence over the real name (reason?)
unnamed structs should be processed for all the languages
nested C struct instances are wrapped as "immutable"
tree building
typedef declaration for unnamed C structures fixed
nested classes "flattening"
fixed %ignoring nested classes
renamed "nested" attribute to "nested:outer" added "nested" flag, to be used with $ignore (it is not removed while flattening) added nestedClassesSupported() function to the Language interface
renamed "nested" attribute to "nested:outer" added "nested" flag, to be used with $ignore (it is not removed while flattening) added nestedClassesSupported() function to the Language interface
tree iteration fix
dirclassname variable names unified memory issue fixed
merge error
ignore unnamed structs for C++
unnamed nested C structs naming & unnesting
class added to classes hash under typedef name
private nested classes skipped
test updated due to nested templates support
anonymous structs with inheritance fixed nested_class test to allow anonymous structs w/o declarator
tests updated: nested workaround removed from namespace_class.i propagated nested template declaration to the C++ file
injected members scope
nested tempplates fixes, nested structures in "C" mode parsing added utility function "appendSibling" (like "appendChild")
nested unnamed structures parsing fixes, access mode restored on nested class end, tdname is properly patched with outer class name prefix
memory management fixes
