* <para>This threading model has the caveat that it is only safe to call
* Clutter's API when the lock has been acquired &mdash; which happens
* between pairs of clutter_threads_enter() and clutter_threads_leave()
* calls.</para>
* <para>The only safe and portable way to use the Clutter API in a
* multi-threaded environment is to never access the API from a thread that
* did not call clutter_init() and clutter_main().</para>
* <para>The common pattern for using threads with Clutter is to use worker
2011-10-03 10:56:26 -04:00
* threads to perform blocking operations and then install idle or timeout
* sources with the result when the thread finished.</para>
* <para>Clutter provides thread-aware variants of g_idle_add() and
* g_timeout_add() that acquire the Clutter lock before invoking the provided
* callback: clutter_threads_add_idle() and
* clutter_threads_add_timeout().</para>

Store the motion event deliver flag in ClutterStage Once upon a time, the land of Clutter had a stage singleton. It was created automatically at initialization time and stayed around even after the main loop was terminated. The singleton was content in being all there was. There also was a global API to handle the configuration of the stage singleton that would affect the behaviour on other classes, signals and properties. Then, an evil wizard came along and locked the stage singleton in his black tower, and twisted it until it was possible to create new stages. These new stages were pesky, and didn't have the same semantics of the singleton: they didn't stay around when closed, or terminate the main loop on delete events. The evil wizard also started moving all the stage-related API from the global context into class-specific methods. Finally, the evil wizard cast a spell, and the stage singleton was demoted to creation on demand - and until somebody called the clutter_stage_get_default() function, the singleton remained in a limbo of NULL pointers and undefined memory areas. There was a last bit - literally - of information still held by the global API; a tiny, little flag that disabled per-actor motion events. The evil wizard added private accessors for it, and stored it inside the stage private structure, in preparation for a deprecation that would come in a future development cycle. The evil wizard looked down upon the land of Clutter from the height of his black tower; the lay of the land had been reshaped into a crucible of potential, and the last dregs of the original force of creation were either molted into new, useful shapes, or blasted away by the sheer fury of his will. All was good.

Adds initial clipped redraw support to Clutter A new (internal only currently) API, _clutter_actor_queue_clipped_redraw can be used to queue a redraw along with a clip rectangle in actor coordinates. This clip rectangle propagates up to the stage and clutter backend which may optionally use the information to optimize stage redraws. The GLX backend in particular may scissor the next redraw to the clip rectangle and use GLX_MESA_copy_sub_buffer to present the stage subregion. The intention is that any actors that can naturally determine the bounds of updates should queue clipped redraws to reduce the cost of updating small regions of the screen. Notes: » If GLX_MESA_copy_sub_buffer isn't available then the GLX backend ignores any clip rectangles. » queuing multiple clipped redraws will result in the bounding box of each clip rectangle being used. » If a clipped redraw has a height > 300 pixels then it's promoted into a full stage redraw, so that the GPU doesn't end up blocking too long waiting for the vsync to reach the optimal position to avoid tearing. » Note: no empirical data was used to come up with this threshold so we may need to tune this. » Currently only ClutterX11TexturePixmap makes use of this new API. This is done via a new "queue-damage-redraw" signal that is emitted when the pixmap is updated. The default handler queues a clipped redraw with the assumption that the pixmap is being painted as a rectangle covering the actors transformed allocation. If you subclass ClutterX11TexturePixmap and change how it's painted you now also need to override the signal handler and queue your own redraw. Technically this is a semantic break, but it's assumed that no one is currently doing this. This still leaves a few unsolved issues with regards to optimizing sub stage redraws that need to be addressed in further work so this can only be considered a stepping stone a this point: » Because we have no reliable way to determine if the painting of any given actor is being modified any optimizations implemented using _clutter_actor_queue_redraw_with_clip must be overridable by a subclass, and technically must be opt-in for existing classes to avoid a change in semantics. E.g. consider that a user connects to the paint signal for ClutterTexture and paints a circle instead of a rectangle. In this case any original logic to queue clipped redraws would be incorrect. » Currently only the implementation of an actor has enough information with which to queue clipped redraws. E.g. It is not possible for generic code in clutter-actor.c to queue a clipped redraw when hiding an actor because actors have no way to report a "paint box". (remember actors can draw outside their allocation and actors with depth may also be projected outside of their allocation) » The current plan is to add a actor_class->get_paint_cuboid() virtual so actors can report a bounding cube for everything they would draw in their current state and use that to queue clipped redraws against the stage by projecting the paint cube into stage coordinates. » Our heuristics for promoting clipped redraws into full redraws to avoid blocking the GPU while we wait for the vsync need improving: » vsync issues aren't relevant for redirected/composited applications so they should use different heuristics. In this case we instead need to trade off the cost of blitting when using glXCopySubBuffer vs promoting to a full redraw and flipping instead.

Store the motion event deliver flag in ClutterStage Once upon a time, the land of Clutter had a stage singleton. It was created automatically at initialization time and stayed around even after the main loop was terminated. The singleton was content in being all there was. There also was a global API to handle the configuration of the stage singleton that would affect the behaviour on other classes, signals and properties. Then, an evil wizard came along and locked the stage singleton in his black tower, and twisted it until it was possible to create new stages. These new stages were pesky, and didn't have the same semantics of the singleton: they didn't stay around when closed, or terminate the main loop on delete events. The evil wizard also started moving all the stage-related API from the global context into class-specific methods. Finally, the evil wizard cast a spell, and the stage singleton was demoted to creation on demand - and until somebody called the clutter_stage_get_default() function, the singleton remained in a limbo of NULL pointers and undefined memory areas. There was a last bit - literally - of information still held by the global API; a tiny, little flag that disabled per-actor motion events. The evil wizard added private accessors for it, and stored it inside the stage private structure, in preparation for a deprecation that would come in a future development cycle. The evil wizard looked down upon the land of Clutter from the height of his black tower; the lay of the land had been reshaped into a crucible of potential, and the last dregs of the original force of creation were either molted into new, useful shapes, or blasted away by the sheer fury of his will.

profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git

profile: Update to uprof-0.3 dep for --enable-profile When building with --enable-profile we now depend on the uprof-0.3 developer release which brings a few improvements: » It lets us "fix" how we initialize uprof so that instead of using a shared object constructor/destructor (which was a hack used when first adding uprof support to Clutter) we can now initialize as part of clutter's normal initialization code. As a side note though, I found that the way Clutter initializes has some quite serious problems whenever it involves GOptionGroups. It is not able to guarantee the initialization of dependencies like uprof and Cogl. For this reason we still use the contructor/destructor approach to initialize uprof in Cogl. » uprof-0.3 provides a better API for adding custom columns when reporting timer and counter statistics which lets us remove quite a lot of manual report generation code in clutter-profile.c. » uprof-0.3 provides a shared context for tracking mainloop timer statistics. This means any mainloop based library following the same "Mainloop" timer naming convention can use the shared context and no matter who ends up owning the final mainloop the statistics will always be in the same place. This allows profiling of Clutter with an external mainloop such as with the Mutter compositor. » uprof-0.3 can export statistics over dbus and comes with an ncurses based ui to vizualize timer and counter stats live. The latest version of uprof can be cloned from: git://github.com/rib/UProf.git

Fully integrates CoglMaterial throughout the rest of Cogl This glues CoglMaterial in as the fundamental way that Cogl describes how to fill in geometry. It adds cogl_set_source (), which is used to set the material which will be used by all subsequent drawing functions It adds cogl_set_source_texture as a convenience for setting up a default material with a single texture layer, and cogl_set_source_color is now also a convenience for setting up a material with a solid fill. "drawing functions" include, cogl_rectangle, cogl_texture_rectangle, cogl_texture_multiple_rectangles, cogl_texture_polygon (though the cogl_texture_* funcs have been renamed; see below for details), cogl_path_fill/stroke and cogl_vertex_buffer_draw*. cogl_texture_rectangle, cogl_texture_multiple_rectangles and cogl_texture_polygon no longer take a texture handle; instead the current source material is referenced. The functions have also been renamed to: cogl_rectangle_with_texture_coords, cogl_rectangles_with_texture_coords and cogl_polygon respectivly. Most code that previously did: cogl_texture_rectangle (tex_handle, x, y,...); needs to be changed to now do: cogl_set_source_texture (tex_handle); cogl_rectangle_with_texture_coords (x, y,....); In the less likely case where you were blending your source texture with a color like: cogl_set_source_color4ub (r,g,b,a); /* where r,g,b,a isn't just white */ cogl_texture_rectangle (tex_handle, x, y,...); you will need your own material to do that: mat = cogl_material_new (); cogl_material_set_color4ub (r,g,b,a); cogl_material_set_layer (mat, 0, tex_handle)); cogl_set_source_material (mat); Code that uses the texture coordinates, 0, 0, 1, 1 don't need to use cog_rectangle_with_texure_coords since these are the coordinates that cogl_rectangle will use. For cogl_texture_polygon; as well as dropping the texture handle, the n_vertices and vertices arguments were transposed for consistency. So code previously written as: cogl_texture_polygon (tex_handle, 3, verts, TRUE); need to be written as: cogl_set_source_texture (tex_handle); cogl_polygon (verts, 3, TRUE); All of the unit tests have been updated to now use the material API and test-cogl-material has been renamed to test-cogl-multitexture since any textured quad is now technically a test of CoglMaterial but this test specifically creates a material with multiple texture layers. Note: The GLES backend has not been updated yet; that will be done in a following commit.

* This function does the same work as clutter_init(). Additionally,
* it allows you to add your own command line options, and it
* automatically generates nicely formatted <option>--help</option>
* output. Note that your program will be terminated after writing
* out the help output. Also note that, in case of error, the
* error message will be placed inside @error instead of being
* printed on the display.
*
* Just like clutter_init(), if this function returns an error code then
* any subsequent call to any other Clutter API will result in undefined
* behaviour - including segmentation faults.

Remove Units from the public API With the recent change to internal floating point values, ClutterUnit has become a redundant type, defined to be a float. All integer entry points are being internally converted to floating point values to be passed to the GL pipeline with the least amount of conversion. ClutterUnit is thus exposed as just a "pixel with fractionary bits", and not -- as users might think -- as generic, resolution and device independent units. not that it was the case, but a definitive amount of people was convinced it did provide this "feature", and was flummoxed about the mere existence of this type. So, having ClutterUnit exposed in the public API doubles the entry points and has the following disadvantages: - we have to maintain twice the amount of entry points in ClutterActor - we still do an integer-to-float implicit conversion - we introduce a weird impedance between pixels and "pixels with fractionary bits" - language bindings will have to choose what to bind, and resort to manually overriding the API + *except* for language bindings based on GObject-Introspection, as they cannot do manual overrides, thus will replicate the entire set of entry points For these reason, we should coalesces every Actor entry point for pixels and for ClutterUnit into a single entry point taking a float, like: void clutter_actor_set_x (ClutterActor *self, gfloat x); void clutter_actor_get_size (ClutterActor *self, gfloat *width, gfloat *height); gfloat clutter_actor_get_height (ClutterActor *self); etc. The issues I have identified are: - we'll have a two cases of compiler warnings: - printf() format of the return values from %d to %f - clutter_actor_get_size() taking floats instead of unsigned ints - we'll have a problem with varargs when passing an integer instead of a floating point value, except on 64bit platforms where the size of a float is the same as the size of an int To be clear: the *intent* of the API should not change -- we still use pixels everywhere -- but: - we remove ambiguity in the API with regard to pixels and units - we remove entry points we get to maintain for the whole 1.0 version of the API - we make things simpler to bind for both manual language bindings and automatic (gobject-introspection based) ones - we have the simplest API possible while still exposing the capabilities of the underlying GL implementation
