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.

gst/gstbin.c: (de)activate src pads before calling state_change on the childs. Original commit message from CVS: * gst/gstbin.c: (activate_pads), (iterator_activate_fold_with_resync), (gst_bin_src_pads_activate), (gst_bin_change_state_func): (de)activate src pads before calling state_change on the childs. This is to avoid the case where a src ghostpad is blocked (holding the stream lock), which would block the deactivation of the ghostpad's target pad. * gst/gstghostpad.c: (gst_proxy_pad_do_query_type), (gst_proxy_pad_do_event), (gst_proxy_pad_do_query), (gst_proxy_pad_do_internal_link), (gst_proxy_pad_do_bufferalloc), (gst_proxy_pad_do_chain), (gst_proxy_pad_do_getrange), (gst_proxy_pad_do_checkgetrange), (gst_proxy_pad_do_getcaps), (gst_proxy_pad_do_acceptcaps), (gst_proxy_pad_do_fixatecaps), (gst_proxy_pad_do_setcaps), (gst_proxy_pad_set_target_unlocked), (gst_proxy_pad_set_target), (gst_proxy_pad_get_internal), (gst_proxy_pad_dispose), (gst_proxy_pad_init), (gst_ghost_pad_parent_set), (gst_ghost_pad_parent_unset), (gst_ghost_pad_class_init), (gst_ghost_pad_internal_do_activate_push), (gst_ghost_pad_internal_do_activate_pull), (gst_ghost_pad_do_activate_push), (gst_ghost_pad_do_activate_pull), (gst_ghost_pad_do_link), (gst_ghost_pad_do_unlink), (gst_ghost_pad_dispose), (gst_ghost_pad_new_no_target), (gst_ghost_pad_new), (gst_ghost_pad_set_target): GhostPads now create their internal GstProxyPad at creation (and not when they're linked, as it was being done previously). The internal and target pads are linked straight away. The data will also travel through the other pad in order to make pad blocking and probes non-hackish (the probe/block now really happens on the GhostPad and not on the target). * gst/gstpad.c: (gst_pad_set_blocked_async), (gst_pad_link_prepare), (gst_pad_push_event): Remove previous ghostpad cruft. * gst/gstutils.c: (gst_pad_add_data_probe), (gst_pad_add_event_probe), (gst_pad_add_buffer_probe), (gst_pad_remove_data_probe), (gst_pad_remove_event_probe), (gst_pad_remove_buffer_probe): Remove previous ghost pad cruft. Added more detailed debug statements. * tests/check/gst/gstghostpad.c: (GST_START_TEST): Fix the testsuite for refcounting changes. The comments about who has references were correct, but the refcount being checked wasn't the same (!?!).

/**
* SECTION:gstghostpad
* @short_description: Pseudo link pads
* @see_also: #GstPad
*
* GhostPads are useful when organizing pipelines with #GstBin like elements.
* The idea here is to create hierarchical element graphs. The bin element
* contains a sub-graph. Now one would like to treat the bin-element like any
* other #GstElement. This is where GhostPads come into play. A GhostPad acts as
* a proxy for another pad. Thus the bin can have sink and source ghost-pads
* that are associated with sink and source pads of the child elements.
*
* If the target pad is known at creation time, gst_ghost_pad_new() is the
* function to use to get a ghost-pad. Otherwise one can use gst_ghost_pad_new_no_target()
* to create the ghost-pad and use gst_ghost_pad_set_target() to establish the
* association later on.
*
* Note that GhostPads add overhead to the data processing of a pipeline.

This is to avoid the case where a src ghostpad is blocked (holding the stream lock), which would block the deactivation of the ghostpad's target pad. * gst/gstghostpad.c: (gst_proxy_pad_do_query_type), (gst_proxy_pad_do_event), (gst_proxy_pad_do_query), (gst_proxy_pad_do_internal_link), (gst_proxy_pad_do_bufferalloc), (gst_proxy_pad_do_chain), (gst_proxy_pad_do_getrange), (gst_proxy_pad_do_checkgetrange), (gst_proxy_pad_do_getcaps), (gst_proxy_pad_do_acceptcaps), (gst_proxy_pad_do_fixatecaps), (gst_proxy_pad_do_setcaps), (gst_proxy_pad_set_target_unlocked), (gst_proxy_pad_set_target), (gst_proxy_pad_get_internal), (gst_proxy_pad_dispose), (gst_proxy_pad_init), (gst_ghost_pad_parent_set), (gst_ghost_pad_parent_unset), (gst_ghost_pad_class_init), (gst_ghost_pad_internal_do_activate_push), (gst_ghost_pad_internal_do_activate_pull), (gst_ghost_pad_do_activate_push), (gst_ghost_pad_do_activate_pull), (gst_ghost_pad_do_link), (gst_ghost_pad_do_unlink), (gst_ghost_pad_dispose), (gst_ghost_pad_new_no_target), (gst_ghost_pad_new), (gst_ghost_pad_set_target): GhostPads now create their internal GstProxyPad at creation (and not when they're linked, as it was being done previously). The internal and target pads are linked straight away. The data will also travel through the other pad in order to make pad blocking and probes non-hackish (the probe/block now really happens on the GhostPad and not on the target). * gst/gstpad.c: (gst_pad_set_blocked_async), (gst_pad_link_prepare), (gst_pad_push_event): Remove previous ghostpad cruft. * gst/gstutils.c: (gst_pad_add_data_probe), (gst_pad_add_event_probe), (gst_pad_add_buffer_probe), (gst_pad_remove_data_probe), (gst_pad_remove_event_probe), (gst_pad_remove_buffer_probe): Remove previous ghost pad cruft. Added more detailed debug statements. * tests/check/gst/gstghostpad.c: (GST_START_TEST): Fix the testsuite for refcounting changes. The comments about who has references were correct, but the refcount being checked wasn't the same (!?!).

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/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.

(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.
