(pre_activate_switch, post_activate_switch): New stubs, things to do before and after switching activation modes on pads. (gst_pad_set_active): Take a boolean and not a mode, dispatch to the pad's activate function to choose which mode to activate. Shortcut on deactivation and call the right function directly.

(gst_element_pads_activate): Simplified via use of fold and delegation of decisions to gstpad->activate. * gst/gstbus.c (gst_bus_source_finalize): Set the bus to NULL, help in debugging. * gst/gstbuffer.c (_gst_buffer_initialize): Ref the buffer type class once in init, like gstmessage. Didn't run into this issue but it seems correct. Don't initialize a trace, gstminiobject does that. * check/pipelines/simple_launch_lines.c (test_stop_from_app): New test, runs fakesrc ! fakesink, stopping on ::handoff via a message to the bus. (assert_live_count): New util function, uses alloc traces to check cleanup. * check/gst/gstghostpad.c (test_ghost_pads): More refcount checks. To be modified when unlink drops the internal pad.

Feeble attempt at implementing the sync property, needs an unlock method. * gst/base/gstbasetransform.c (gst_base_transform_transform_caps): New func, by default returns the same caps (the identity transformation). (gst_base_transform_getcaps): Uses transform_caps to return something sensible. (gst_base_transform_setcaps): Complicated logic to get caps on both pads, even if they are different, and to call set_caps once for every time both pads get their caps set. (gst_base_transform_handle_buffer): Give the ref to the transform function. Allows in-place modification of the buffer. * gst/base/gstbasetransform.h (transform_caps): New class method. Given caps on one side, what can I do on the other. (set_caps): Take two caps, one for each side of the element. * gst/gstpad.h: * gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify caps in place. This is safe because we can check the mutability of the caps, and a good idea because fixate functions are just called as a matter of last resort. (Not actually implemented.) (gst_pad_set_caps): If the caps we're setting is actually the same as the existing pad caps, just update the pointer without calling setcaps. Assert that caps is either NULL or fixed, as per the docs. * gst/gstghostpad.c: Update for fixate changes.

Original commit message from CVS: 2005-06-27 Andy Wingo <wingo@pobox.com> * gst/base/gsttypefindhelper.c (gst_type_find_helper): Unref any remaining buffer. * gst/gsttrace.c (gst_alloc_trace_list_sorted): New helper, returns a sorted copy of the trace list. (gst_alloc_trace_print_live): New API, only prints traces with live objects. Sort the list. (gst_alloc_trace_print_all): Sort the list. (gst_alloc_trace_print): Align columns. * gst/elements/gstttypefindelement.c: * gst/elements/gsttee.c: * gst/base/gstbasesrc.c: * gst/base/gstbasesink.c: * gst/base/gstbasetransform.c: * gst/gstqueue.c: Adapt for pad activation changes. * gst/gstpipeline.c (gst_pipeline_init): Unref after parenting sched. (gst_pipeline_dispose): Drop ref on sched. * gst/gstpad.c (gst_pad_init): Set the default activate func. (gst_pad_activate_default): Push mode by default. (pre_activate_switch, post_activate_switch): New stubs, things to do before and after switching activation modes on pads. (gst_pad_set_active): Take a boolean and not a mode, dispatch to the pad's activate function to choose which mode to activate. Shortcut on deactivation and call the right function directly. (gst_pad_activate_pull): New API, (de)activates a pad in pull mode. (gst_pad_activate_push): New API, same for push mode. (gst_pad_set_activate_function) (gst_pad_set_activatepull_function) (gst_pad_set_activatepush_function): Setters for new API. * gst/gstminiobject.c (gst_mini_object_new, gst_mini_object_free): Trace all miniobjects. (gst_mini_object_make_writable): Unref the arg if we copy, like gst_caps_make_writable. * gst/gstmessage.c (_gst_message_initialize): No trace init. * gst/gstghostpad.c (gst_proxy_pad_do_activate) (gst_proxy_pad_do_activatepull, gst_proxy_pad_do_activatepush): Adapt for new pad API. * gst/gstevent.c (_gst_event_initialize): Don't initialize trace. * gst/gstelement.h: * gst/gstelement.c (gst_element_iterate_src_pads) (gst_element_iterate_sink_pads): New API functions. * gst/gstelement.c (iterator_fold_with_resync): New utility, should fold into gstiterator.c in some form. (gst_element_pads_activate): Simplified via use of fold and delegation of decisions to gstpad->activate. * gst/gstbus.c (gst_bus_source_finalize): Set the bus to NULL, help in debugging. * gst/gstbuffer.c (_gst_buffer_initialize): Ref the buffer type class once in init, like gstmessage. Didn't run into this issue but it seems correct. Don't initialize a trace, gstminiobject does that. * check/pipelines/simple_launch_lines.c (test_stop_from_app): New test, runs fakesrc ! fakesink, stopping on ::handoff via a message to the bus. (assert_live_count): New util function, uses alloc traces to check cleanup. * check/gst/gstghostpad.c (test_ghost_pads): More refcount checks. To be modified when unlink drops the internal pad.

tests/network-clock.scm: Commentary update. Original commit message from CVS: 2005-07-01 Andy Wingo <wingo@pobox.com> * tests/network-clock.scm: Commentary update. * gst/elements/gstidentity.c (PROP_DUPLICATE): Gone daddy gone. Didn't really make sense, not implementable with basetransform, etc. (gst_identity_transform): Unref inbuf via make_writable. Feeble attempt at implementing the sync property, needs an unlock method. * gst/base/gstbasetransform.c (gst_base_transform_transform_caps): New func, by default returns the same caps (the identity transformation). (gst_base_transform_getcaps): Uses transform_caps to return something sensible. (gst_base_transform_setcaps): Complicated logic to get caps on both pads, even if they are different, and to call set_caps once for every time both pads get their caps set. (gst_base_transform_handle_buffer): Give the ref to the transform function. Allows in-place modification of the buffer. * gst/base/gstbasetransform.h (transform_caps): New class method. Given caps on one side, what can I do on the other. (set_caps): Take two caps, one for each side of the element. * gst/gstpad.h: * gst/gstpad.c (gst_pad_fixate_caps): Change prototype to modify caps in place. This is safe because we can check the mutability of the caps, and a good idea because fixate functions are just called as a matter of last resort. (Not actually implemented.) (gst_pad_set_caps): If the caps we're setting is actually the same as the existing pad caps, just update the pointer without calling setcaps. Assert that caps is either NULL or fixed, as per the docs. * gst/gstghostpad.c: Update for fixate changes.
