check/net/gstnetclientclock.c (test_functioning): Adjust to rate_num/rate_denom change. Original commit message from CVS: 2005-11-23 Andy Wingo <wingo@pobox.com> * check/net/gstnetclientclock.c (test_functioning): Adjust to rate_num/rate_denom change. * gst/net/gstnetclientclock.c (gst_net_client_clock_observe_times): Take the SLAVE_LOCK not the OBJECT_LOCK. Don't call add_observation with the lock. * gst/gstclock.c (gst_clock_init): Initialize the rate as a fraction. (gst_clock_adjust_unlocked): Adjust using uint64_scale and the rate fraction. (gst_clock_set_calibration, gst_clock_get_calibration): Change to deal with rate as a fraction whose numerator and denominator are GstClockTime values. (gst_clock_set_master): Only use the OBJECT_LOCK to set the master; the other fields are protected by the SLAVE_LOCK. (do_linear_regression): Note that this must be called with the SLAVE_LOCK. (gst_clock_add_observation): Take the SLAVE_LOCK, not the OBJECT_LOCK. Call set_calibration instead of touching the variables directly. (gst_clock_set_property, gst_clock_get_property): Protect master/slave parameters with the SLAVE_LOCK. * gst/gstclock.h (GstClock): Remove rate, add rate_numerator and rate_denominator. PR3C1S3. Add a new lock, the SLAVE_LOCK, and note that all of the instance variables that add_observation and the set_master functions use are protected by that lock and not the OBJECT_LOCK. (GST_CLOCK_SLAVE_LOCK, GST_CLOCK_SLAVE_UNLOCK): New macros. * gst/gstclock.c (gst_clock_add_observation): No longer requires the caller to take the object lock.
