docs/pwg/advanced-types.xml: Fix description for buffer-frames=0. Original commit message from CVS: * docs/pwg/advanced-types.xml: Fix description for buffer-frames=0. * docs/gst/tmpl/gstbin.sgml: * gst/gstbin.c: (gst_bin_child_state_change_func), (gst_bin_change_state), (gst_bin_change_state_norecurse): * gst/gstbin.h: * testsuite/threads/Makefile.am: * testsuite/threads/threadi.c: (cb_timeout), (cb_quit), (cb_eos), (cb_state), (cb_play), (main): Fix non-recursive state changes to *really* change the state of the object, and not just call parent_class->state_change. Fix a lot of lockups caused by this. Fixes #132775. Add test for the problem. Also enable test to show #142588 (fixed). * gst/gstthread.c: (gst_thread_change_state), (gst_thread_child_state_change): Don't exit the thread if we go to NULL and are inside thread context. Instead, return control to the main thread context and exit from there. * gst/gstelement.c: (gst_element_disable_threadsafe_properties): Don't unset virtual functions, since those may still be used. That's not necessarily correct, but suffices for now. * configure.ac: * testsuite/Makefile.am: * testsuite/pad/Makefile.am: * testsuite/pad/chainnopull.c: (gst_test_sink_class_init), (gst_test_sink_base_init), (gst_test_sink_chain), (gst_test_sink_init), (main): * testsuite/pad/getnopush.c: (gst_test_src_class_init), (gst_test_src_base_init), (gst_test_src_get), (gst_test_src_init), (main): * testsuite/pad/link.c: (gst_test_element_class_init), (gst_test_element_base_init), (gst_test_src_get), (gst_test_src_loop), (gst_test_src_init), (gst_test_filter_chain), (gst_test_filter_loop), (gst_test_filter_init), (gst_test_sink_chain), (gst_test_sink_loop), (gst_test_sink_init), (cb_error), (main): Add tests to show #150546. Pass, but should fail (currently disabled from the testsuite). * gst/gstscheduler.c: (gst_scheduler_dispose): Dereference child schedulers on dispose (#94464). * testsuite/bytestream/filepadsink.c: (gst_fp_sink_init): Fix typo. * testsuite/threads/thread.c: (main): Add more debug.
