Original commit message from CVS:
* docs/design/part-TODO.txt:

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.
Original commit message from CVS:
* gst/base/gstbasesink.c: (gst_base_sink_class_init),
(gst_base_sink_wait), (gst_base_sink_do_sync),
(gst_base_sink_handle_event):
* gst/base/gstbasesink.h:
No need to store the clock, the parent element class already
has it.
* gst/gstbin.c: (gst_bin_set_clock_func), (gst_bin_add_func):
Updates for clock_set returning a gboolean
* gst/gstclock.c: (gst_clock_entry_new), (gst_clock_id_wait),
(gst_clock_id_wait_async), (gst_clock_class_init),
(gst_clock_init), (gst_clock_finalize),
(gst_clock_get_internal_time), (gst_clock_get_time),
(gst_clock_slave_callback), (gst_clock_set_master),
(gst_clock_get_master), (do_linear_regression),
(gst_clock_add_observation), (gst_clock_set_property),
(gst_clock_get_property):
* gst/gstclock.h:
Implement master/slave. When setting a clock as a slave, a
periodic timeout is scheduled to sample master and slave times.
Then the slave clock is recalibrated to match offset and rate
of the master clock.
Update logging a bit.
Add flag so that a clock can state that is cannot be slaved to
another clock.
* gst/gstelement.c: (gst_element_set_clock):
* gst/gstelement.h:
The set_clock returns a gboolean for when an element cannot
deal with the selected clock in the pipeline.
* gst/gstpipeline.c: (gst_pipeline_change_state),
(gst_pipeline_set_clock):
* gst/gstpipeline.h:
Handle the case where the selected clock cannot be set on
the pipeline.
* gst/net/gstnetclientclock.c: (gst_net_client_clock_class_init),
(gst_net_client_clock_init), (gst_net_client_clock_finalize),
(gst_net_client_clock_set_property),
(gst_net_client_clock_get_property),
(gst_net_client_clock_observe_times):
* gst/net/gstnetclientclock.h:
Use regression code in GstClock parent, remove duplicated
functionality.

* gst/net/gstnetclientclock.c: Turn off debugging.
* check/net/gstnetclientclock.c (test_functioning): Assert that the
times connverge somewhat. Can't make a real test.

* gst/net/gstnetclientclock.c (do_linear_regression): Use all
integer arithmetic. Return the minimum of the domain, which can be
set as "internal" for gst_clock_set_calibration.
(gst_net_client_clock_observe_times): Call _set_calibration.
(gst_net_client_clock_new): Call _set_calibration instead of
rate_offset.
* check/net/gstnetclientclock.c (test_functioning): Use the right
adjustment api.
* gst/gstclock.h:
* gst/gstclock.c (gst_clock_get_calibration)
(gst_clock_set_calibration): New functions, obsolete the ones I
added yesterday. Doh. Precision issues mean we have to extrapolate
from a point in the more recent past than 1970.
(gst_clock_get_rate_offset, gst_clock_set_rate_offset): Mark as
obsolete.
(gst_clock_adjust_unlocked): Use the right calibration data.

* gst/net/gstnetclientclock.c (gst_net_client_clock_thread):
Whoops, check the right fd. Also add some debugging.
(gst_net_client_clock_observe_times): Adjust for int64 offset.
(do_linear_regression): Add a crapload of debugging. Subtract off
the minimum values from the input series to discard unneeded bits.
Use only int arithmetic. There is still double arithmetic when
calculating the intercept that needs fixing. Return boolean to
indicate success; FALSE would mean the domain or range is too
great. Still needs fixes.

* gst/net/gstnetclientclock.c (gst_net_client_clock_class_init):
Port goes all the way to MAXUINT16.
* gst/net/gstnettimeprovider.c: Make the port range the same as
for the kernel: 0 assigns, otherwise ports are less than
MAXUINT16.
* check/net/gstnettimeprovider.c: Adapt for 0 == kernel assigns
port change.
* check/net/gstnetclientclock.c (test_functioning): Add the start
of another test.

* gst/net/gstnetclientclock.c (gst_net_client_clock_new): Adjust
the clock initially so it produces values around the base time.
(gst_net_client_clock_class_init): Typo fix.
(gst_net_client_clock_thread): Add note on when the socket gets
closed.
Original commit message from CVS:
* gst/net/gstnetclientclock.c: (do_linear_regression),
(gst_net_client_clock_do_select), (gst_net_client_clock_thread):
Fix compilation, uninitialized vars and a forgotten continue.

* check/Makefile.am (check_PROGRAMS):
* check/net/gstnetclientclock.c: Add a most minimal test for the
net client clock. More to come later.
* gst/net/gstnet.h:
* gst/net/Makefile.am: Add netclientclock.
* gst/net/gstnetclientclock.h:
* gst/net/gstnetclientclock.c: New files, implement an untested
GstClock that takes its time from a network time provider.
Implements the algorithm in network-clock.scm.
* tests/network-clock.scm (*window-size*): Rename from
*queue-length*.
* tests/network-clock.scm (network-time):
* tests/network-clock-utils.scm (q-push): Update callers.
