Some of the ClutterDebugFlags are not meant as a logging facility: they
actually change Clutter's behaviour at run-time.
It would be useful to have this distinction ratified, and thus split
ClutterDebugFlags into two: one DebugFlags for logging facilities and
another set of flags for behavioural changes.
This split is warranted because:
• it should be possible to do "CLUTTER_DEBUG=all" and only have
log messages on the output
• it should be possible to use behavioural modifiers even on a
Clutter that has been compiled without debugging messages
support
The commit adds two new debugging flags:
ClutterPickDebugFlags - controlled by the CLUTTER_PICK environment
variable
ClutterPaintDebugFlags - controlled by the CLUTTER_PAINT environment
variable
The PickDebugFlags are:
nop-picking
dump-pick-buffers
While the PaintDebugFlags is:
disable-swap-events
The mechanism is equivalent to the CLUTTER_DEBUG environment variable,
but it does not depend on the debug level selected when configuring and
compiling Clutter. The picking and painting debugging flags are
initialized at clutter_init() time.

Now if you export CLUTTER_DEBUG=dump-pick-buffers clutter will write out a
png, e.g. pick-buffer-00000.png, each time _clutter_to_pick() is called.
It's a rather crude way to debug the picking (realtime visualization in a
second stage would probably be nicer) but it we've used this approach
successfully numerous times when debugging Clutter picking issues so it
makes sense to have a debug option for it.
The right gcc define is __GNUC__ not __GNUC_. This typo had the side
effect that we were using the non gcc specific debug macros leading to
a less optmised CLUTTER_NOTE () than one could have dreamed of.
I've found this is something I do quite often when debugging rendering
problems since its a simple way to wipe out lots of geometry and removes a
lot of unpredictable noise when logging geometry passing through the Cogl
journal.
If we need to check that the layout sequence is correct in
terms of order of execution and with respect to caching, then
having a CLUTTER_DEBUG_LAYOUT debug flag would make things
easier.
Bug 1014 - Clutter Animation API Improvements
* clutter/Makefile.am:
* clutter/clutter.h: Update the build
* clutter/clutter-types.h: Add AnimationMode, an enumeration
for easing functions.
* clutter/clutter-alpha.[ch]: Add the :mode property to
control the function bound to an Alpha instance using an
enumeration value. Also add six new alpha functions:
- ease-in, ease-out, ease-in-out
- sine-in, sine-out, sine-in-out
* clutter/clutter-deprecated.h: Deprecate the #defines for
the alpha functions. They will be replaced by entries in the
ClutterAnimationMode.
* clutter/clutter-interval.[ch]: Add ClutterInterval, an
object for defining, validating and computing an interval
between two values.
* clutter/clutter-animation.[ch]: Add ClutterAnimation, an
object responsible for animation the properties of a single
actor along an interval of values. ClutterAnimation memory
management is automatic. A simple wrapper method for
ClutterActor is provided:
clutter_actor_animate()
which will create, or update, an animation for the passed
actor.
* clutter/clutter-debug.h:
* clutter/clutter-main.c: Add a new 'animation' debug note.
* clutter/clutter-script.c: Clean up the alpha functions
whitelist, and add the new functions.
* doc/reference/clutter/Makefile.am:
* doc/reference/clutter/clutter-sections.txt: Update the
API reference.
* doc/reference/clutter/clutter-animation.xml: Renamed to
doc/reference/clutter/clutter-animation-tutorial.xml to
avoid clashes with the ClutterAnimation section.
* doc/reference/clutter/clutter-docs.sgml: Renamed to
doc/reference/clutter/clutter-docs.xml, as it was an XML
file and not a SGML file.
* tests/Makefile.am:
* tests/interactive/Makefile.am:
* tests/interactive/test-animation.c:
* tests/interactive/test-easing.c: Add two tests for the
new simple animation API and the easing functions.
* tests/interactive/test-actors.c:
* tests/interactive/test-behave.c:
* tests/interactive/test-depth.c:
* tests/interactive/test-effects.c:
* tests/interactive/test-layout.c:
* tests/interactive/test-multistage.c:
* tests/interactive/test-paint-wrapper.c:
* tests/interactive/test-rotate.c:
* tests/interactive/test-scale.c:
* tests/interactive/test-texture-quality.c:
* tests/interactive/test-threads.c:
* tests/interactive/test-viewport.c: Update interactive tests
to the deprecations and new alpha API.
* clutter/clutter-score.h: Rearrange declarations.
* clutter/clutter-score.c: More documentation in the long
description of the ClutterScore section.
* clutter/clutter-debug.h:
* clutter/clutter-main.c: Add the CLUTTER_DEBUG_SHADER flag,
for debugging the shader calls.
* clutter/clutter-feature.h: Fix the documentation of the
feature flags.
* clutter/Makefile.am: Remove trailing whitespace.
Portability fixes:
* clutter/clutter-private.h:
Bracket #include "unistd.h" with #ifdef HAVE_UNISTD_H
* clutter/clutter-fixed.c:
Use "", not <> for inclusion of local files.
(clutter_sqrtx): forward declare local variables.
* clutter/clutter-debug.h:
Added non-gcc (c99) implementation of variadic debug macros for
when not compiling with gcc.
* clutter/pango/pangoclutter-render.c:
Fixed some strange uses of CLUTTER_NOTE() + stripped trailing
whitespace.
Initial implementation of the UI definition files. (#424)
* clutter/json/Makefile.am:
* clutter/json/*.[ch]: In-tree copy of JSON-GLib, a GLib-based
JSON parser/generator library. We use it in-tree because we might
need to change the API. Ideally, we'd depend on it.
* clutter/clutter.h:
* clutter/clutter-script-private.h:
* clutter/clutter-script.[ch]: ClutterScript, the scenegraph
generator class. It parses JSON streams in form of buffers and
files and builds the scene.
* clutter/clutter-debug.h:
* clutter/clutter-main.c: Add a "script" debug flag
* clutter/Makefile.am: Build glue.
* tests/Makefile.am:
* tests/test-script.c: Add a test case for the ClutterScript.
* configure.ac: Depend on GLib 2.14, so we can use the
g_hash_table_get_key() and g_hash_table_get_values() functions
for the time being; we can probably reimplement those, but we
are going to need 2.14 anyway if we are going to implement a
list model using GSequence.
* clutter/Makefile.am:
* clutter/clutter-debug.h:
* clutter/clutter-fixed.h:
* clutter/clutter-main.c:
* clutter/cogl/gles/Makefile.am:
* clutter/cogl/gles/cogl-defines.h:
* clutter/cogl/gles/cogl.c:
* clutter/egl/clutter-backend-egl.c:
* clutter/egl/clutter-backend-egl.h:
* clutter/egl/clutter-stage-egl.c:
* configure.ac:
Populate most stubs for cogl GL/ES implementation.
(against vincent - see http://svn.o-hand.com/repos/misc/ogles)
Add various fixups to EGL backend.
Code builds and runs (on 16bpp) but yet displays much (is close!)
* clutter/pango/pangoclutter-render.c:
comment out some rouge glBegin/end calls.
* clutter/clutter-actor.c:
* clutter/clutter-alpha.c:
* clutter/clutter-behaviour-opacity.c:
* clutter/clutter-behaviour-scale.c:
* clutter/clutter-clone-texture.c:
* clutter/clutter-feature.c:
* clutter/clutter-label.c:
* clutter/clutter-main.c:
* clutter/clutter-stage.c:
* clutter/clutter-texture.c
* clutter/clutter-timeline.c:
* clutter/clutter-debug.h:
Make CLUTTER_NOTE() just take a string rather than a func.
Add more default context to output.
* configure.ac:
Fix flag and add more help docs for --ebable-debug option.
* configure.ac: Enable debug messages also when
--enable-debug is set to "minimum".
* clutter/Makefile.am:
* clutter/clutter-debug.h: Move all debugging macros inside
this private header; make all debug macros depend on the
CLUTTER_ENABLE_DEBUG compile time define, controlled by
the --enable-debug configure switch; add G_LOG_DOMAIN define.
* clutter/clutter-main.c: Clean up the debug stuff; add
command line argument parsing using GOption; the debug
messages now are triggered like this:
CLUTTER_DEBUG=section:section:... clutter-app
or like this:
clutter-app --clutter-debug=section:section:...
where "section" is one of the sections listed in clutter-main.c,
or "all", for all sections; each section is bound to a flag,
which can be used to define a domain when adding a debug note
using the CLUTTER_NOTE() macro; the old CLUTTER_DBG() macro is
just a wrapper around that, under the CLUTTER_DEBUG_MISC domain;
CLUTTER_NOTE() is used like this:
CLUTTER_NOTE (DOMAIN, log-function);
where log function is g_printerr(), g_message(), g_warning(),
g_critical() or directly g_log() - for instance:
CLUTTER_NOTE (PANGO, g_warning ("Cache miss: %d", glyph));
will print the warning only if the "pango" flag has been
set to the CLUTTER_DEBUG envvar or passed to the --clutter-debug
command line argument.
similar to CLUTTER_SHOW_FPS, there's also the --clutter-show-fps
command line switch; also, the --display and --screen command
line switches have been added: the first overrides the DISPLAY
envvar and the second controls the X screen used by Clutter to
get the root window on the display.
* clutter/clutter-main.h:
* clutter/clutter-main.c: Add extended support for GOption
in Clutter; use clutter_init_with_args() to let Clutter
parse your own command line arguments; use instead
clutter_get_option_group() to get the GOptionGroup used by
Clutter if you want to do the parsing yourself with
g_option_context_parse(). The init sequence has been verified,
updated and moved into common functions where possible.
* clutter/pango/pangoclutter-render.c:
* clutter/*.c: Include "clutter-debug.h" where needed; use
CLUTTER_NOTE() instead of CLUTTER_DBG().
* examples/super-oh.c: Use the new clutter_init_with_args()
function, and add a --num-hands command line switch to
the SuperOH example code controlling the number of hands at
runtime.
