gst/gstutils.c: RPAD fixes all around. Original commit message from CVS: 2005-06-08 Andy Wingo <wingo@pobox.com> * gst/gstutils.c: RPAD fixes all around. (gst_element_link_pads): Refcounting fixes. * tools/gst-inspect.c: * tools/gst-xmlinspect.c: * parse/grammar.y: * gst/base/gsttypefindhelper.c: * gst/base/gstbasesink.c: * gst/gstqueue.c: RPAD fixes. * gst/gstghostpad.h: * gst/gstghostpad.c: New ghost pad implementation as full proxy pads. The tricky thing is they provide both source and sink interfaces, since they proxy the internal pad for the external pad, and vice versa. Implement with lower-level ProxyPad objects, with the interior proxy pad as a child of the exterior ghost pad. Should write a doc on this. * gst/gstpad.h: s/RPAD/PAD/, s/RealPad/Pad/. (gst_pad_set_name, gst_pad_set_parent): Macros removed, use gst_object API. * gst/gstpad.c: Big changes. No more stub base GstPad, now all pads are real pads. No ghost pads in this file. Not documenting the myriad s/RPAD/PAD/ and REALIZE fixes. (gst_pad_class_init): Add properties for "direction" and "template". Both are construct-only, so they can't change during the life of the pad. Fixes properly deriving from GstPad. (gst_pad_custom_new, gst_pad_custom_new_from_template): Gone. For derived objects, just set properties when creating the objects via g_object_new. (gst_pad_get_parent): Implement as a function, return NULL if the parent is not an element. (gst_pad_get_real_parent, gst_pad_add_ghost_pad) (gst_pad_remove_ghost_pad, gst_pad_realize): Removed. * gst/gstobject.c (gst_object_class_init): Make name a construct property. Don't set it in the object init. * gst/gstelement.c (gst_element_add_pad): Don't allow adding pads with UNKNOWN direction. (gst_element_add_ghost_pad): Remove non-orthogonal API. Replace with gst_element_add_pad (e, gst_ghost_pad_new (name, pad)). (gst_element_remove_pad): Remove ghost-pad special cases. (gst_element_pads_activate): Remove rpad cruft. * gst/gstbin.c (gst_bin_change_state): Use gst_pad_get_parent to catch the pad's-parent-not-an-element case. * gst/gst.h: Include gstghostpad.h. * gst/gst.c (init_post): No more real, ghost pads. * gst/Makefile.am: Add gstghostpad.[ch]. * check/Makefile.am: * check/gst/gstbin.c: * check/gst/gstghostpad.c (test_ghost_pads): Check that linking into a bin creates ghost pads, and that the refcounts are right. Partly moved from gstbin.c.

gst/gstquery.h Original commit message from CVS: 2005-05-06 Andy Wingo <wingo@pobox.com> * gst/gstquery.h * gst/gstquery.c (_gst_query_initialize): Extend GstQuery from GstData, init a memchunk. (standard_definitions): Add a few query types, deprecate a few. (gst_query_get_type): New proc. (_gst_query_copy, _gst_query_free, gst_query_new): GstData implementation. (gst_query_new_application, gst_query_get_structure): New public procs. * docs/design/draft-query.txt: Removed LINKS from the query types, because all the rest can be dispatched to other pads -- seemed ugly to have a query that couldn't be dispatched. internal_links is fine as a pad method. * gst/gstpad.h: Add query2 as a pad method, add the new functions in gstpad.c, but maintain binary compatibility for the moment. Will fix before 0.9 is out. * gst/gstqueryutils.c: * gst/gstqueryutils.h: New files, implement 3 methods for each query type: parse_query, parse_response, and set. Probably need an allocator as well. * gst/gst.h: Add gstquery.h and gstqueryutils.h to the list. * gst/elements/gstfilesink.c (gst_filesink_query2): * gst/base/gstbasesrc.c (gst_basesrc_query2): Replace old query, query_types, and formats methods. * gst/gstpad.c (gst_pad_query2, gst_pad_query2_default) (gst_pad_set_query2_function): New functions. (gst_real_pad_init): Set query2_default as the default query2 function. Basically just dispatches to internally linked pads. Needs review! * gst/gstdata_private.h (_GST_DATA_INIT): Set data->refcount to 1 without using the atomic operations. Only one thread can possibly be accessing the data at this point. Changed so as to avoid gst_atomic operations.
