This time, in Clutter core.
The ObjC standard library provides a type called 'id', which obviously
requires any library to either drop the useful shadowed variable warning
or stop using 'id' as a variable name.
Yes, it's almost unbearably stupid. Well, at least it's not 'index' in
string.h, or 'y2' in math.h.
ClutterAnimator currently has a number of bugs related to its
referencing of its internal timeline.
1) The default timeline created in _init is not unreffed (it appears the
programmer has wrongly thought ClutterTimeline has a floating reference
based on the use of g_object_ref_sink in _set_timeline)
2) The timeline and slave_timeline vars are unreffed in finalize instead
of dispose
3) The signal handlers set up in _set_timeline are not disconnected when
the animator is disposed

When removing all keys in a ClutterAnimator, the hash table with
object/property name pairs went out of sync. This change makes
the animator always clear this hash table upon key-removal; and
refreshing it if the animator's timeline is running.
Fixes bug #2335
This adds a wrapper macro to clutter-private that will use
g_object_notify_by_pspec if it's compiled against a version of GLib
that is sufficiently new. Otherwise it will notify by the property
name as before by extracting the name from the pspec. The objects can
then store a static array of GParamSpecs and notify using those as
suggested in the documentation for g_object_notify_by_pspec.
Note that the name of the variable used for storing the array of
GParamSpecs is obj_props instead of properties as used in the
documentation because some places in Clutter uses 'properties' as the
name of a local variable.
Mose of the classes in Clutter have been converted using the script in
the bug report. Some classes have not been modified even though the
script picked them up as described here:
json-generator:
We probably don't want to modify the internal copy of JSON
behaviour-depth:
rectangle:
score:
stage-manager:
These aren't using the separate GParamSpec* variable style.
blur-effect:
win32/device-manager:
Don't actually define any properties even though it has the enum.
box-layout:
flow-layout:
Have some per-child properties that don't work automatically with
the script.
clutter-model:
The script gets confused with ClutterModelIter
stage:
Script gets confused because PROP_USER_RESIZE doesn't match
"user-resizable"
test-layout:
Don't really want to modify the tests

Duplicate the existing ease-in/interpolation mode for the property when
removing, replacing the first key for a property or adding a new first
key for a property.
When inserting or modifying keys of a running animator the internal
iterators per property could go out of sync. Reinitializing the
iterators if the timeline is running avoids this.
We should explain what a "key frame" is for ClutterAnimator, possibly
with some sort of visual cue.
This allows me to demonstrate my poor skills at using Inkscape, as well
as my overall bad taste for graphics design.
It would be useful to be able to share the Timeline across different
animator instances, or with different animation constructs. Also this
allows sharing definitions of Timelines in ClutterScript.
The arguments for remove_key() can be NULL, but there is an extraneous
assertion that fails if they are. The pre-conditions should match the
documentation, in this case.
A bogus ClutterInterpolation argument had been carried from
clutter_animator_set_interpolation to clutter_animator_get_interpolation
in copy and paste.
GLib 2.24 (but starting from the 2.23.2 unstable release) added a new
macro for collecting GValues from a va_list.
The newly added G_VALUE_COLLECT_INIT() macro should be used in place
of initializing the GValue and calling G_VALUE_COLLECT(), and improves
the collection performances by avoiding multiple checks, free and
initialization calls.
Do not de-reference a void*; use a temporary variable -- after
checking the contents of the pointer. This actually simplifies
the readability and avoids pulling a Lisp with the parentheses.
The whole point of having the Animator class is that the developer can
describe a complex animation using ClutterScript. Hence, ClutterAnimator
should hook into the Script machinery and parse a specific description
format for its keys.
When asking a key for its target value we also ask the developer to pass
in an initialized GValue - but we don't make it easy to know the type of
the GValue. A developer has to ask the GObject class for the GParamSpec
and then initialize the GValue, instead.
Since we know the type of the GValue we should provide a getter for it.
We should also allow developers to throw at us GValue with compatible and
transformable types.
Finally, all the accessors should be constified.
