Mon Aug 9 12:48:04 2004 Matthias Clasen <maclas@gmx.de> Add hidden aliases for exported symbols which are used internally in order to get rid of many PLT entries. (#145519, Arjan van de Ven) * gtk/Makefile.am: Add rules to generate gtk.def and from gtk.symbols, and make make check check the abi with abicheck.sh. (gtk_private_h_sources): Add gtkinternals.h (gtk_built_private_headers): Add gtkalias.h (gtk_extra_sources): Add gtk.symbols (EXTRA_DIST): Add makegtkalias.pl and abicheck.sh * gtk/gtk.symbols: New file. Definition of the GTK+ ABI. The file can be processed by cpp to filter out certain subsets of symbols. * gtk/abicheck.sh: New file. Script to check the actually symbols exported from libgtk-x11.2.0.so against the symbols found in gtk.symbols. * gtk/makegtkalias.pl: New file. Perl script to generate the header containing the alias definitions for internally used exported symbols from a list of symbols. * gtk/gtkinternals.h: New file. An uninstalled header listing symbols which must be exported for some reason and do not appear in any other header. * gtk/*.c: Include gtkalias.h

* Weak references.
|
|
*
|
|
* Weak refs are very similar to the old "destroy" signal. They allow
|
|
* one to register a callback that is called when the weakly
|
|
* referenced object is finalized.
|
|
*
|
|
* They are not implemented as a signal because they really are
|
|
* special and need to be used with great care. Unlike signals, which
|
|
* should be able to execute any code whatsoever.
|
|
*
|
|
* A weakref callback is not allowed to retain a reference to the
|
|
* object. Object data keys may be retrieved in a weak reference
|
|
* callback.
|
|
*
|
|
* A weakref callback is called at most once.
