The commit 40bf877 fixed warnings about converting between function and object
pointers but introduced warnings about breaking strict-aliasing rules which
appear with -Wstrict-aliasing which is implicitly enabled by -O2.
Avoid these warnings as well by using an intermediate union for conversion
instead of casts trickery.
Fix and document the naturalvar feature override behaviour - the naturalvar
feature attached to a variable name has precedence over the naturalvar
feature attached to the variable's type. The overriding was not working
when turning the feature off on the variable's name.
Fix so that any use of the naturalvar feature will override the global
setting. Previously when set globally by -naturalvar or %module(naturalvar=1),
use of the naturalvar feature was not always honoured.
Work around harmless (at least under POSIX systems where function pointers are
guaranteed to have the same representation as object pointers) but annoying
warnings given by gcc when converting between function and object pointers, e.g.
Source/DOH/fio.c: In function 'DohEncoding':
Source/DOH/fio.c:51: warning: ISO C forbids conversion of function pointer to object pointer type
Source/DOH/fio.c: In function 'encode':
Source/DOH/fio.c:75: warning: ISO C forbids conversion of object pointer to function pointer type
Source/DOH/base.c: In function 'DohCall':
Source/DOH/base.c:952: warning: ISO C forbids conversion of object pointer to function pointer type
Use an extra level of pointer indirection to avoid them.
This changeset resolves several issues related to python imports.
For example, it's possible now to import modules having same module
names, but belonging to different packages.
From the user's viewpoint, this patch gives a little bit more control on
import directives generated by swig. The user may choose to use relative
or absolute imports (docs are provided in separate PR).
Some details:
- we (still) generate import directives in form 'import a.b.c' which
corresponds to absolute imports in python3 and (the only available)
ambiguous one in python2.
- added -relativeimport option to use explicit relative import syntax
(python3),
Tests are under Examples/python, these are in fact regression tests but
with the current swig testing framework it seems to be impossible to put
appropriate tests under test-suite.

try adding travis ci to this branch
ran "beautify-file" make target over perl5.cxx patch hunks and rewrote callback and extend examples in the style of existing examples
prefer polymorphism on existing destructor over custom destructor method
fix string mangled by tidy
eliminate dead director code and convert remaining blocks
mitigate ConvertPtr director cost when directors are not enabled

adds "callback" and "extend" examples
don't forget the most important part
steals python directors and adapts to perl5
fixed language symbol table nested classes name separator, test added
fixed %feature "flatnested" working with %extend
fixed Swig_offset_string for empty string
added simple template to save/restore values in current scope (readability reasons)

Deprecation of the 'nestedworkaround' feature
Ensure -c++out is not used with -c++
Add missing header to new source file
Nested C class setters restored in c++out mode for Octave
Classprefix fixed after private nested classes some comments and spaces added
Fix template partial specialization detection
Minor tweaks in Swig_feature_set
Swig_offset_string moved to misc.c
nested private classes are discarded while parsing nested relate functions are moved to nested.cxx and renamed accordingly
out-of-scope template definitions fixed nested_private test disabled again
fixed out-of-scope nested class definitions, added a test enabled nested C structs assignment (still disabled for Octave), added Java runtime test fixed nested_private test case for Java & C#
Testcase of private nested class usage causing segfault
C nested struct passed by value example
Add in Travis testing for nested branch
Add C++ nested class example
Minor code improvements
Cosmetics/code beautification of nested class support
Nested classes support
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.
Suitable casts are required so that assignment of instances of nested classes
work as the nested class is duplicated in the global namespace, eg:
struct Outer {
struct Nested {
int bar;
} bar_instance;
};
Outer.bar_instance can now be assigned to.
changed to be consistent with other languages. The typemaps
provided by SWIG have been updated accordingly, but if you
have written your own directorout typemaps, you'll need to
update $input to &$input (or make equivalent changes).
*** POTENTIAL INCOMPATIBILITY ***
Fixes template definitions that should be ignored and warnings introduced after nested changes:
../../../Examples/test-suite/refcount.i:63: Warning 318: Instantiation of template 'RCPtr< A >' is ambiguous,
../../../Examples/test-suite/refcount.h:159: Warning 318: instantiation 'RCPtr< T >::RCPtr' used,
../../../Examples/test-suite/refcount.h:159: Warning 318: instantiation 'RCPtr< T >::RCPtr' ignored.
../../../Examples/test-suite/refcount.h:159: Warning 318: instantiation 'RCPtr< T >::RCPtr' ignored.
../../../Examples/test-suite/refcount.h:159: Warning 318: instantiation 'RCPtr< T >::RCPtr' ignored.
Different/clearer implementation of constructor detection since Classprefix is
not behaving the same since nested changes were introduced. Only accept
constructors if in extend mode or in a class.
Also remove unused "isextension" attribute on the nodes.
