Version 1.3.20 (In progress)
============================
11/18/2003: mkoeppe (Matthias Koeppe)
[Guile] Change meaning of configure option --with-guile to
the name of the Guile executable. The new option --with-guile-prefix
can be used to specify the tree where Guile is
installed. (However, usually it suffices to use the
single option --with-guile-config.)
When running the run tests test-suite, make sure to use the
version of Guile that SWIG was configured for.
11/17/2003: mkoeppe (Matthias Koeppe)
[Guile] Improvements to object-ownership management in
"-scm" mode. (They do not apply to the default "-gh" mode.)
* Renamed the smob type that indicates that the object can
be garbage collected from "collected swig" to "collectable
swig", which is more precise.
* Export the destructor functions again. It is now
allowed to explicitly call destructors, even for
garbage-collected pointer objects. A pointer object
that has been passed to a destructor is marked in a
special way using a new smob type, "destroyed swig".
(This helps avoid nasty memory bugs, where references to
dead C objects are still held in Scheme. Moreover, the
garbage collector will not try to free a destroyed
object once more.)
* Destructor-like functions can also mark their arguments
as destroyed by applying the typemap SWIGTYPE *DESTROYED.
(It calls the function SWIG_Guile_MarkPointerDestroyed.)
* Functions that "consume" their objects (or that "own"
them after the call) can mark their arguments as
not garbage collectable. This can be done by applying
the typemap SWIGTYPE *CONSUMED. (It calls the function
SWIG_Guile_MarkPointerNoncollectable.)
* The macro TYPEMAP_POINTER_INPUT_OUTPUT from library
pointer-in-out.i creates additional typemaps
PTRTYPE *INPUT_CONSUMED, PTRTYPE *INPUT_DESTROYED.
They mark the passed pointer object likewise.
The typemap PTRTYPE *OUTPUT creates a garbage-collectable
pointer object, like %newobject does for a returned
pointer. Use the new typemap PTRTYPE *OUTPUT_NONCOLLECTABLE
to create a pointer object that will not be garbage collected.
11/17/2003: mkoeppe (Matthias Koeppe)
[Guile] Handle $input in "freearg" typemaps.
Never qualify GOOPS slot names with the class name.
Handle optional arguments properly in the GOOPS methods.
11/16/2003: cheetah (William Fulton)
Fixes for installation to work with the upcoming Automake-1.8.
mkinstalldirs was being used by a non-Automake makefile.
