2003-05-26 Michael Natterer <mitch@gimp.org> * app/base/tile-manager-private.h: added "gint ref_count" to the TileManager struct. * app/base/tile-manager.[ch]: replaced tile_manager_destroy() by tile_manager_ref() and tile_manager_unref(). * app/core/gimpimage-undo-push.c: ref the tile managers stored in the undo system and DON'T destroy them if no undo could be pushed. Should fix the remaining crashes with undo disabled like in bug #9350. (!!!) Note that the tiles passed to gimp_image_undo_push_image() and gimp_drawable_push_undo() as well as the tile managers of drawables passed to gimp_image_undo_push_[layer|channel]_mod() must be unref'ed by the caller now. * app/core/gimpdrawable-transform.c (gimp_drawable_transform_paste): don't take ownership of the passed tiles but ref them if needed. (!!!) Callers must unref the passed tiles themselves now. * app/core/gimpbuffer.c * app/core/gimpdrawable-blend.c * app/core/gimpdrawable-bucket-fill.c * app/core/gimpdrawable-offset.c * app/core/gimpdrawable.c * app/core/gimpedit.c * app/core/gimpimage-convert.c * app/core/gimpimage-mask.c * app/core/gimpimage-projection.c * app/core/gimpimage.c * app/core/gimpimagemap.c * app/core/gimplayer-floating-sel.c * app/core/gimplayer.c * app/paint/gimppaintcore.c * app/text/gimptextlayer.c * app/tools/gimpinktool.c * app/tools/gimpiscissorstool.c * app/tools/gimptransformtool-undo.c * app/tools/gimptransformtool.c: changed accordingly.
