Original commit message from CVS: 2004-02-20 Andy Wingo <wingo@pobox.com> * gst/gstbin.c: * gst/gstbuffer.c: * gst/gstplugin.c: * gst/registries/gstxmlregistry.c: * gst/schedulers/gstoptimalscheduler.c: Debugging tweaks. * gst/gstelement.c (gst_element_set_scheduler): Debugging fixes. (gst_element_add_pad): DEBUG->INFO, some fixes. (gst_element_get_compatible_pad_template): Just see if the templates' caps intersect, not if one is a strict subset of the other. This conforms more to what gst_pad_link_intersect() does. (gst_element_class_add_pad_template): Don't memcpy the pad template, just ref it. (gst_element_get_compatible_pad_filtered): Clean up debug messages * gst/gstpad.c (gst_pad_can_link_filtered): Debug a true result. (gst_pad_link_filtered): Debug changes. (gst_pad_link_prepare): New function, consolidated from can_link_filtered and link_filtered. * gst/parse/grammar.y (gst_parse_perform_link): Made INFO output look more like that of the functions in gstelement.c * gst/gstinfo.c (gst_debug_print_object): Put a space before the object, and return the empty string if object is NULL. * gst/parse/parse.l: Remove trailing newlines when calling PRINT. * gst/parse/grammar.y (YYFPRINTF): Log bison debugging info via LOG, not DEBUG. We still get flex info on debug. * gst/registries/gstxmlregistry.c (gst_xml_registry_load): Make debug string more verbose. (plugin_times_older_than): DEBUG->LOG.
