Original commit message from CVS: 2005-02-10 Andy Wingo <wingo@pobox.com> * testsuite/caps/value_serialize.c: merge from HEAD. * testsuite/caps/subtract.c: * testsuite/caps/filtercaps.c: * testsuite/caps/enumcaps.c: * testsuite/caps/deserialize.c: * testsuite/caps/caps.c: * testsuite/caps/audioscale.c: Unref caps, not free. * testsuite/caps/caps_strings: Merged from HEAD. * gst/elements/gstidentity.c (gst_identity_proxy_getcaps): Getcaps implementation for identity. * gst/gststructure.h * gst/gststructure.c (gst_caps_structure_fixate_field_nearest_double): (gst_caps_structure_fixate_field_nearest_int): Moved from gstcaps.c because we need the private IS_MUTABLE macro. (IS_MUTABLE): New macro, determines if a structure is mutable or not. (gst_structure_free): Don't allow free while holding a pointer to a parent's refcount. (gst_structure_set_name): Check for writability. (gst_structure_id_set_value): Same. (gst_structure_set_value): Same. (gst_structure_set_valist): Same. (gst_structure_remove_field): Same. (gst_structure_remove_all_fields): Same. (gst_structure_map_in_place): New routine, like _foreach but allows the function to mutate the value (via a non-const prototype). Check for writability. (gst_structure_foreach): Redefine to only take non-mutating functions. * gst/gstcaps.c (IS_WRITABLE): New macro, returns TRUE if the caps are writable. (gst_caps_copy): Add some docs about mutability, etc. (_gst_caps_free): Set the parent refcount pointer on structures to NULL before freeing them. (gst_caps_ref): Document. (gst_caps_make_writable): Doc. (gst_caps_make_writable): Changed to make_writable, get_writable sounds too much like retrieving a property. (gst_caps_copy_1): Removed, not very useful. (gst_caps_ref_by_count): Removed, no need to have something GLib doesn't. (gst_caps_copy_conditional): Ref instead of copying. (gst_static_caps_get): Retain a reference to the returned caps, so that the static caps will remain immutable. (gst_caps_remove_and_get_structure): Set the parent refcount to NULL when removing the structure. (gst_caps_append): Fix to work with structure parent refcounts. Check for writability. (gst_caps_append_structure): Check for writability, work with parent refcounts. (gst_caps_remove_structure): Check for writability. (gst_caps_set_simple): Check for writability. (gst_caps_set_simple_valist): Check for writability. (gst_caps_is_fixed_foreach): Update for non-mutating foreach. (gst_structure_is_equal_foreach): Same. (gst_caps_structure_intersect_field): Same. (gst_caps_structure_subtract_field): Same. Make static. (gst_caps_normalize_foreach): Same. (gst_caps_structure_figure_out_union): Same. (gst_caps_switch_structures): New static function, switches out structures inside a caps, taking care of parent_refcount setting. * gst/gstpad.c (gst_pad_get_allowed_caps): Remove the restriction on only src pads, wim von masterhack claims it was bogus. * testsuite/caps/Makefile.am * testsuite/caps/app_fixate.c: Removed app_fixate test, things are done a bit differently in THREADED.
