All 2D coordinate spaces in Cogl have their origin at the top-left so we
shouldn't be flipping the coordinates we pass to
cogl_framebuffer_swap_region to be relative to the bottom of the
framebuffer.
This bumps the Cogl version requirement to 1.7.5 since we've had to fix
a bug in the semantics of cogl_framebuffer_swap_region.

Clutter may be used together with GTK+, which indirectly may use
XInput2 too, so the cookie data must persist when both are handling
events.
What happens now in a nutshell is, Clutter is only guaranteed to allocate
the cookie itself after XNextEvent(), and only frees the cookie if its
XGetEventData() call allocated the cookie data.
The X[Get|Free]EventData() calls happen now in clutter-event-x11.c as
hypothetically different event translators could also handle other set
of X Generic Events, or other libraries handling events for that matter.
If we're building on/for Windows, set 'win32' as the default flavour; if
we're building on OS X, set 'osx' as the default flavour. For everything
else, use 'glx'.
If we're building on/for Windows, set 'win32' as the default flavour; if
we're building on OS X, set 'osx' as the default flavour. For everything

Since some experimental API in Cogl that Clutter uses has changed this
bumps our dependency up to 1.7.3 before landing the corresponding build
fixes for clutter to bring it in line with the Cogl changes.
This adds a performance tracking framework that can run a set of tests over
specified git revisions. The ruby script for generating the reports comes from
similar performance tracking in GEGL. The framework permits evaluating new
tests against older version of clutter.
The tests themselves go through a few hoops for disabling framerate limiting in
both mesa and clutter.
When running make check the tests will be run and lines of the form:
@ test-state: 40.51 fps
will be left in the output, a script can scrape these lines out of a build log
on a buildbot to in other ways track performance.
Since GLX and EGL are abstracted by Cogl the two backends are both
implementing everything using the Cogl API and they are almost
identical.
This updates the egl backend to support everything that the glx backend
supports. Now that EGL and GLX are abstracted by Cogl, the plan is that
we will squash the clutter-egl/glx backends into one. Since the EGL
backend in clutter can conditionally not depend on X11 we will use the
EGL backend as the starting point of our common backend.

In test-pixmap.c instead of using the GdkPixbuf API to load the
redhand.png image we now use the cairo API to load the png into a xlib
surface which wraps our Pixmap.
This test was the last thing that depended on the gdk API and since
it's more concise to use Cairo here which is a hard dependency for
Clutter this change means we avoid depending on GdkPixbuf directly.
Cogl has now been split out into a standalone project with a separate
repository at git://git.gnome.org/cogl. From now on the Clutter build
will now simply look for a cogl-1.0 pkg-config file to find a suitable
Cogl library to link against at build time.
We want to be able to split Cogl out as a standalone project but there
are still some window systems that aren't natively supported by Cogl.
This allows Clutter to support those window systems directly but still
work with a standalone Cogl library.
This also ensures we set the SUPPORT_STUB conditional in clutter's
configure.ac when building for win32/osx and wayland.
This adds a simple standalone Cogl application that can be used to
smoke test a standalone build of Cogl without Clutter.
This also adds an x11-foreign app that shows how a toolkit can ask Cogl
to draw to an X Window that it owns instead of Cogl being responsible
for automatically creating and mapping an X Window for CoglOnscreen.
This allows more detailed control over the driver and winsys features
that Cogl should have. Cogl is designed so it can support multiple
window systems simultaneously so we have enable/disable options for
the drivers (gl vs gles1 vs gles2) and options for the individual window
systems; currently glx and egl. Egl is broken down into an option
for each platform.
The GDL API is used for example on intel ce4100 (aka Sodaville) based
systems as a way to allocate memory that can be composited using the
platforms overlay hardware. This updates the Cogl EGL winsys and the
support in Clutter so we can continue to support these platforms.
As was recently done for the GLX window system code, this commit moves
the EGL window system code down from the Clutter backend code into a
Cogl winsys.
Note: currently the cogl/configure.ac is hard coded to only build the GLX
winsys so currently this is only available when building Cogl as part
of Clutter.
The "DRM_SURFACELESS" EGL platform was invented when we were adding the
wayland backend to Clutter but in the end we added a dedicated backend
instead of extending the EGL backend so actually the platform name isn't
used.
This backend hasn't been used for years now and so because it is
untested code and almost certainly doesn't work any more it would be a
burdon to continue trying to maintain it. Considering that we are now
looking at moving OpenGL window system integration code down from
Clutter backends into Cogl that will be easier if we don't have to
consider this backend.
This makes it possible to build Clutter against a standalone build of
Cogl instead of having the Clutter build traverse into the clutter/cogl
subdirectory.
This adds an autogen.sh, configure.ac and build/autotool files etc under
clutter/cogl and makes some corresponding Makefile.am changes that make
it possible to build and install Cogl as a standalone library.
Some notable things about this are:
A standalone installation of Cogl installs 3 pkg-config files;
cogl-1.0.pc, cogl-gl-1.0.pc and cogl-2.0.pc. The second is only for
compatibility with what clutter installed though I'm not sure that
anything uses it so maybe we could remove it. cogl-1.0.pc is what
Clutter would use if it were updated to build against a standalone cogl
library. cogl-2.0.pc is what you would use if you were writing a
standalone Cogl application.
A standalone installation results in two libraries currently, libcogl.so
and libcogl-pango.so. Notably we don't include a major number in the
sonames because libcogl supports two major API versions; 1.x as used by
Clutter and the experimental 2.x API for standalone applications.
Parallel installation of later versions e.g. 3.x and beyond will be
supportable either with new sonames or if we can maintain ABI then we'll
continue to share libcogl.so.
The headers are similarly not installed into a directory with a major
version number since the same headers are shared to export the 1.x and
2.x APIs (The only difference is that cogl-2.0.pc ensures that
-DCOGL_ENABLE_EXPERIMENTAL_2_0_API is used). Parallel installation of
later versions is not precluded though since we can either continue
sharing or later add a major version suffix.
This migrates all the GLX window system code down from the Clutter
backend code into a Cogl winsys. Moving OpenGL window system binding
code down from Clutter into Cogl is the biggest blocker to having Cogl
become a standalone 3D graphics library, so this is an important step in
that direction.
On win32, test scripts are created with a .exe extension.
Under mingw, a .exe script is launched in 16 bit compatibility mode (through
ntvdm), and so it just does not run.

GCC by default allows pointer arithmetic on void* pointers and treats
them as having a size of 1 byte. This is non-standard behaviour and
causes errors on some compilers so we should try to avoid
it. -Wpointer-arith warns about these cases.
We use the micro version for distinguishing released tarballs and Git
builds; the maintainer compiler flags should be enabled for the latter,
and not just for unstable cycles, since it makes sense to have extra
warning flags even on stable cycles.
We also want to allow people to turn on -Werror on demand, so let's add
a third option to --enable-maintainer-flags.
Since we have a decent XI1 and XI2 implementation, now, we should turn
the support for XInput on by default.
The actual implementation to be used at run-time is still left to be
decided by the user.
This is a lump commit that is fairly difficult to break down without
either breaking bisecting or breaking the test cases.
The new design for handling X11 event translation works this way:
- ClutterBackend::translate_event() has been added as the central
point used by a ClutterBackend implementation to translate a
native event into a ClutterEvent;
- ClutterEventTranslator is a private interface that should be
implemented by backend-specific objects, like stage
implementations and ClutterDeviceManager sub-classes, and
allows dealing with class-specific event translation;
- ClutterStageX11 implements EventTranslator, and deals with the
stage-relative X11 events coming from the X11 event source;
- ClutterStageGLX overrides EventTranslator, in order to
deal with the INTEL_GLX_swap_event extension, and it chains up
to the X11 default implementation;
- ClutterDeviceManagerX11 has been split into two separate classes,
one that deals with core and (optionally) XI1 events, and the
other that deals with XI2 events; the selection is done at run-time,
since the core+XI1 and XI2 mechanisms are mutually exclusive.
All the other backends we officially support still use their own
custom event source and translation function, but the end goal is to
migrate them to the translate_event() virtual function, and have the
event source be a shared part of Clutter core.
Clutter has some platform-specific API that is accessible only if the
right backend has been compiled in. Third party applications that wish
to be portable across backends might want to use defines and other
pre-processor tricks to determine header inclusion and API usage.
While Clutter has an internal set of symbols it can use, third party
applications don't have the luxury of being able to access the config.h
generated by Clutter's configure script.
For this reason, Clutter should install a configuration header with a
series of namespaced defines that can be picked up by applications and
other third party code.
The ffs function is defined in C99 so if we want to use it in Cogl we
need to provide a fallback for MSVC. This adds a configure check for
the function and then a fallback using a while loop if it is not
available.

Keeping the Cogl 2.0 API reference in the build is getting far more
troublesome than it's worth.
It's breaking distcheck far too often, and it makes it impossible to
rebuild the build environment from tarballs - which is something that
some distributions (namely: the Debian-based ones, but not limited to
them) do in order to change build scripts using their own rules.
The check-news option in configure.ac conflicts with the idea of using a
buildbot to do a distcheck.
Since we're doing some validation on the state of the build during the
release-check phase we should add the NEWS file check there.
http://bugzilla.clutter-project.org/show_bug.cgi?id=2468
Not tested (but checked that it compiles).
There's no reason to only enable the check for the cex100. Hopefully
should work.
We make sure not to enable both the evdev and the tslib backend at the
same time as the DeviceManager is a singleton and we can't have both
subclasses at the same time for now.
This backend is a event backend that can be enabled for EGL (for now).
It uses udev (gudev) to query input devices on a linux system, listens to
keyboard events from input devices and xkbcommon to translate raw key
codes into key keysyms.
This commit only supports key events, more to follow.
Building the API reference for Cogl 2.0 is fairly confusing: the API
itself is experimental and for internal use only -- though we want
feedback for it.
Let's build the API reference only when Clutter is configured with a
specific configure switch, so that people that wish to give feedback on
the API and its documentation can do it.
So we can keep track of the experimental progress of Cogl 2.0 features
this adds a standalone Cogl 2.0 Reference Manual which doesn't cover
the deprecated 1.x symbols and removes the need for a "Cogl
experimental API" chapter since those sections now make up the main
table of contents.
By defining COGL_ENABLE_EXPERIMENTAL_2_0_API in config.h we can ensure
that all internal clutter and cogl code can use the Cogl 2.0 API and by
not using AM_CPPFLAGS we avoid having other tools such as glib-mkenums
and the gir-scanner from inadvertently using the define also.
The profiling support was broken - probably during the restructuring of
the build environment, but I'm too lazy to bisect that.
The fix is trivial, and everything works as it should.
Previously in the tests/tools directory we build a disable-npots
library which was used as an LD_PRELOAD to trick Cogl in to thinking
there is no NPOT texture extension. This is a little awkward to use so
it seems much simpler to just define a COGL_DEBUG option to disable
npot textures.
CLUTTER_EGL_BACKEND is used to define a special EGL native backend to
use and was introduced for the CEX100 EGL backend. Unfortunately
CLUTTER_EGL_BACKEND was defined to "cex100" for eglnative, which is
obviously wrong.
The paches defines the right values for CLUTTER_EGL_BACKEND for the
eglnative and cex100 flavours.
Don't generate both bz2 and gz tarballs: we only use the former anyway,
and the latter just adds time for distcheck to complete.
The gz tarball will be generated by the remote installation scripts when
publishing the release.
The internal copy of JSON-GLib was meant to go away right after the 1.0
release, given that JSON-GLib was still young and relatively unknown.
Nowadays, many projects started depending on this little library, and
distributions ship it and keep it up to date.
Keeping a copy of JSON-GLib means keeping it up to date; unfortunately,
this would also imply updating the code not just for the API but for the
internal implementations.
Starting with the 1.2 release, Clutter preferably dependend on the
system copy; with the 1.4 release we stopped falling back automatically.
The 1.6 cycle finally removes the internal copy and requires a copy of
JSON-GLib installed on the target system in order to compile Clutter.
*** WARNING: THIS COMMIT CHANGES THE BUILD ***
Do not recurse into the backend directories to build private, internal
libraries.
We only recurse from clutter/ into the cogl sub-directory; from there,
we don't recurse any further. All the backend-specific code in Cogl and
Clutter is compiled conditionally depending on the macros defined by the
configure script.
We still recurse from the top-level directory into doc, clutter and
tests, because gtk-doc and tests do not deal nicely with non-recursive
layouts.
This change makes Clutter compile slightly faster, and cleans up the
build system, especially when dealing with introspection data.
Ideally, we also want to make Cogl part of the top-level build, so that
we can finally drop the sed trick to change the shared library from the
GIR before compiling it.
Currently disabled:
‣ OSX backend
‣ Fruity backend
Currently enabled but untested:
‣ EGL backend
‣ Windows backend
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
Let's try to keep Cogl's build as non-recursive as possible, in the hope
that one day we'll be able to make it fully non-recursive along with the
rest of Clutter.
This requires some autotools magic when setting up the environment
through autogen.sh, because autoreconf does not do the right thing
by default.
The correct order for setting up localization is:
‣ autopoint
‣ aclocal
‣ ...
otherwise aclocal will copy the system's gettext.m4 instead of honouring
the version we specified with AM_GNU_GETTEXT_VERSION in configure.ac.
Some debugging tools might require full visibility for the Clutter
symbols; for this reason, and to match what the Clutter dependencies
already allow, we should provide a configure switch to disable linking
with the -Bsymbolic flag.

Intel CE3100 and CE4100 have several planes (framebuffers) and a
hardware blender to blend the planes togeteher to produce the final

clutter_cex100_set_plane() lets you configure which framebuffer clutter
will use for its rendering.
Intel CE3100 and CE4100 SoCs are designed for TVs. They have separate
framebuffers that are blended together by a piece of hardware to make
the final output. The library that allows you to initialize and
configure those planes is called GDL. A EGL GDL winsys can then be
use with those planes as NativeWindowType to select which plane to use.
This patch adds a new ClutterBackendCex100 backend that can be
selected at compile time with the new --with-flavour=cex100 option.
--quiet has been added to g-ir-scanner in the 0.9.1 cycle. We really
want to be able to compile clutter with 0.6.14 to be able to reuse
gir files that are distributed in current distributions.
Use the INTROSPECTION_SCANNER_ARGS (previously unused) variable to
convey --quiet when necessary.

In 7fae8ac051 the two cogl-defines.h files from GLES and GL were
unified. However this missed out the COGL_HAS_GLES[12] defines from
GLES. The configure.ac still made an AC_SUBST for the right version
but the replacement was never put in any headers. This fixes it so
that instead of directly calling AC_SUBST the value is now put into a
variable which later gets added to COGL_DEFINES so that it will end up
in cogl-defines.h
There was an initializer for the COGL_DEFINES variable which sets it
to the empty value before it is filled in. The name of the variable
wasn't spelt right so it wouldn't work properly. This doesn't really
matter because it would default to empty anyway.
The cookbook should also include fully functional code examples. We can
even XInclude them into the docbook XML itself.
The examples should be built with the coobook, so that we can always
make sure they are up to date.
The P_() macro adds a context for the property nick and blurb. In order
to make xgettext recognize it, we need to drop glib-gettexize inside the
autogen.sh script and ship a modified Makefile.in.in with Clutter.
The AS_ALL_LINGUAS m4 macro allows configure-time generation of the
ALL_LINGUAS variable from the translations inside po/ instead of using
the LINGUAS file.

Under big GL, glext.h is included automatically by gl.h. However under
GLES this doesn't appear to happen so it has to be included explicitly
to get the defines for extensions. This patch changes the
clutter_gl_header to be called cogl_gl_headers and it can now take a
space seperated list of multiple headers. This is then later converted
to a list of #include lines which ends up cogl-defines.h. The gles2

This copies the files for the GLU tesselator from Mesa. The Mesa code
is based on the original SGI code and is released under a BSD license.
The memalloc.h header has been replaced with one that forces the code
to use g_malloc and friends. The rest of the files are not altered
from the original so it should be possible to later upgrade the files
by simply overwriting them.
There is a tesselator.h header which is expected to be included by
rest of Cogl to use the tesselator. This contains a trimmed down
version of glu.h that only includes parts that pertain to the
tesselator. There is also a stub glu.h in the GL directory which is
just provided so that the tesselator code can include <GL/gl.h>
without depending on the system header. It just redirects to
tesselator.h
The -Bsymbolic-functions linker flag allows to avoid intra-library
PLT jumps on ELF platforms. It is similar to the aliasing hack in
GLib and GTK+, but definitely less messy.
The configure script should look for the flags, in order to support
platforms/linkers that do not have it.
This will be defined in cogl-defines.h whenever Cogl is built using a
winsys that supports X11. This implies CoglTexturePixmapX11 will be
available.
To make this work the two separate cogl-defines.h.in files have been
merged into one. The configure script now makes a @COGL_DEFINES@
substitution variable which contains the #define lines to put in
rather than directly having them in the seperate files.
When configuring the glx flavour we were always explicitly adding -lGL
to the linker flags even when a pkg-config file was found which should
take care of that option for us.
When building for gles1/2 we now always try and look for a libglesv1_cm
or libglesv2 .pc file with details about where to find the library and
headers.
This adds an automake USE_TSLIB condition to decide when we should
compile clutter-event-tslib.c. This is in preparation for consolidating
the eglx and eglnative backends.
With this patch if you ./configure clutter using
--with-flavour=opengl-egl-xlib then it will use EGL + OpenGL instead of
the default GLX and OpenGL.
These days upstream driver work is more focused on improving EGL than it
is GLX so likewise we want to make sure Clutter has good support for
EGL.
This adds a separate variable name "CLUTTER_SONAME_INFIX" to define the
infix for the clutter library that gets linked. Currently the WINSYS
corresponds to the directory we enter when building to compile the
window system and input support, but it is desirable to be able to
define multiple flavours that use the same WINSYS but should result in
different library names.
For example we are planning to combine the eglx and eglnative window
systems into one "egl" winsys but we will need to preserve the current
library names for the eglx and eglnative flavours.
When we check the flavour we now just set boolean variables for the
following things:
SUPPORT_X11=1
SUPPORT_XLIB=1
SUPPORT_GLX=1
SUPPORT_EGL=1
SUPPORT_EGL_POWERVR_X11=1
SUPPORT_EGL_POWERVR_NULL=1
This lets us avoid some duplication and also some error prone tests for
lists of flavours used, for example, to determine when we need to check
for x libraries.
It's desirable to have a separation between the "flavour" and the
"winsys". The flavour is a concept internal to the configure script and
is a convenient name to represent the users choice of window system,
opengl driver and input backend. The CLUTTER_WINSYS currently defines
the subdirectory under clutter/ that should be compiled to handle the
window system and input.
With a separation we could add a flavour with no correspondence to which
clutter/subdirectory needs to be built.
After checking the flavour option the user gives we were checking for
the fruity flavour to override the glesversion. Now that the glsl
checking has been moved this can instead just wait until the AS_CASE
that handles all the flavour configuration.
The flavour AS_CASE should define whether a flavour uses the gl or gles
COGL_DRIVER and so we shouldn't need to have an expanding list of
tests to gate when we check for a gles driver because if we move the
checks for gles after the flavour checks we can just look at
$COGL_DRIVER.
This removes EGL_{LIBS,CFLAGS}, GLX_{LIBS,CFLAGS}, OSX_{LIBS,CFLAGS},
WIN32_{LIBS,CFLAGS}, and GLES_{LIBS,CFLAGS} and instead we just append
to FLAVOUR_{LIBS,CFLAGS}.
This makes more of the file relocatable because there were previously
dependencies on the order that some variables were setup in.

The AM_PATH_GLIB_2_0 doesn't automatically cause the configure script
to fail if the test fails. This wouldn't usually cause any problems
because we later check for the right glib version using
PKG_CHECK_MODULES directly. However AM_PATH_GLIB_2_0 is more thorough
when checking because it also tries to run a program against the
library to read the version. If the macro fails but the pkg-config
check passes then nothing will define GLIB_GENMARSHAL and the build
step will fail in a confusing way.
This adds a check for the result and gives an AC_MSG_ERROR if it
fails. The glib dependencies have been moved out of CLUTTER_DEPS to
AM_PATH_GLIB_2_0.

The system JSON-GLib installation should be the preferred way of parsing
JSON in Clutter. The internal copy is limited by re-synchronization from
upstream, and by the fact that upstream contains a fork of GScanner that
allows parsing escaped UTF-8. We should warn users compiling Clutter
with the internal copy, just like we warn about the internal image
backend.
The X11TexturePixmap actor uses XComposite API directly, without guards.
It has been doing so for a while, against the fact that we do check for
the XComposite extension - but we don't depend on it. As soon as you try
building Clutter on X11 without the XComposite extension available all
hell breaks loose.
The obvious fix is to make Clutter depend on XComposite - basically
ratifying what's the current state of things.
Update the configure.ac to use the LT_INIT() instead of the deprecated
AC_PROG_LIBTOOL. This also allows us to depend on a specific libtool
version, namely one that doesn't thoroughly suck.
There is no need for us to check for low-level functions and header
files, especially since we haven't been checking the results until
now. This makes cross-compiling slightly more bearable.
Require automake >= 1.10, and add the following options:
» dist-bzip2: create a bz2 tarball in the dist process
» check-news: check that we changed the NEWS file prior to dist,
to avoid another release without NEWS updates, like 1.1.10
We basically want all Clutter applications out in the wild to at least
have the basic set of COGL_DEBUG/--cogl-debug options available for
investigating issues.
The SDL API is far too limited for the windowing system needs of
Clutter; the status of the SDL backend was always experimental, and
since the Windows platform is supported by a native backend there is
no point in having the SDL backend around any more.
When using pkg-config to check for the x11 package compiler flags and
libraries we actually need to retrieve those values from the pc file.
This should also fix the issue with non-canonical installations of the
X11 headers and shared objects.

The win32 backend now handles the WM_SETCURSOR message and sets a
fully transparent cursor if the cursor-visible property has been
cleared on the stage. The icon is stored in the library via a resource
file. The instance handle for the DLL is needed to load the resource
so there is now a DllMain function to grab the handle.
This adds gives Cogl a dedicated UProf context which will be linked together
with Clutter's context during clutter_init_real().
Initial timers cover _cogl_journal_flush and _cogl_journal_log_quad
You can explicitly ask for a report of Cogl statistics by exporting
COGL_PROFILE_OUTPUT_REPORT=1 but since the context is linked with Clutter's
the statisitcs will also be shown in the automatic Clutter reports.
• Make the manual a DevHelp book
• Make the generation of PDFs of the cookbook and the manual optional
• Consequently, make the hard dependency on jw optional
• Clean up the checks and build for the additional documentation
Instead of creating stand-alone HTML files, use XSLT to transform the
DocBook into a DevHelp file, so that we can read the Cookbook inside
DevHelp -- just like the API reference.
The "Clutter Cookbook" is a document designed to contain solutions
to common problems applications developers might encounter when using
Clutter. It is meant as a companion to the API reference but it
requires knowledge of the Clutter API and framework.
The main COGL header cogl.h is currently created at configure time
because it conditionally includes the driver-dependent defines. This
sometimes leads to a stale cogl.h with old definitions which can
break the build until you clean out the whole tree and start from
scratch.
We can generate a stable cogl-defines.h at build time from the
equivalent driver-dependent header and let cogl.h include that
file instead.
We should generate a ChangeLog for each minor version cycle, starting
from the Git import date (since before that we used ChangeLog-style
commit messages that don't really look good with the Git ones).
For this reason we can take Cairo's Makefile.am.changelog file and,
after tweaking it to fit our use case, let it generate the correct
ChangeLogs on dist.
Some changes to make COGL pass distcheck with Automake 1.11 and
anal-retentiveness turned up to 11.
The "major" change is the flattening of the winsys/ part of COGL,
which is built directly inside libclutter-cogl.la instead of an
intermediate libclutter-cogl-winsys.la object.
Ideally, the whole COGL should be flattened out using a
quasi-non-recursive Automake layout; unfortunately, the driver/
sub-section ships with identical targets and Automake cannot
distinguish GL and GLES objects.
As part of an incremental process to have Cogl be a standalone project we
want to re-consider how we organise the Cogl source code.
Currently this is the structure I'm aiming for:
cogl/
cogl/
<put common source here>
winsys/
cogl-glx.c
cogl-wgl.c
driver/
gl/
gles/
os/ ?
utils/
cogl-fixed
cogl-matrix-stack?
cogl-journal?
cogl-primitives?
pango/
The new winsys component is a starting point for migrating window system
code (i.e. x11,glx,wgl,osx,egl etc) from Clutter to Cogl.
The utils/ and pango/ directories aren't added by this commit, but they are
noted because I plan to add them soon.
Overview of the planned structure:
* The winsys/ API is the API that binds OpenGL to a specific window system,
be that X11 or win32 etc. Example are glx, wgl and egl. Much of the logic
under clutter/{glx,osx,win32 etc} should migrate here.
* Note there is also the idea of a winsys-base that may represent a window
system for which there are multiple winsys APIs. An example of this is
x11, since glx and egl may both be used with x11. (currently only Clutter
has the idea of a winsys-base)
* The driver/ represents a specific varient of OpenGL. Currently we have "gl"
representing OpenGL 1.4-2.1 (mostly fixed function) and "gles" representing
GLES 1.1 (fixed funciton) and 2.0 (fully shader based)
* Everything under cogl/ should fundamentally be supporting access to the
GPU. Essentially Cogl's most basic requirement is to provide a nice GPU
Graphics API and drawing a line between this and the utility functionality
we add to support Clutter should help keep this lean and maintainable.
* Code under utils/ as suggested builds on cogl/ adding more convenient
APIs or mechanism to optimize special cases. Broadly speaking you can
compare cogl/ to OpenGL and utils/ to GLU.
* clutter/pango will be moved to clutter/cogl/pango
How some of the internal configure.ac/pkg-config terminology has changed:
backendextra -> CLUTTER_WINSYS_BASE # e.g. "x11"
backendextralib -> CLUTTER_WINSYS_BASE_LIB # e.g. "x11/libclutter-x11.la"
clutterbackend -> {CLUTTER,COGL}_WINSYS # e.g. "glx"
CLUTTER_FLAVOUR -> {CLUTTER,COGL}_WINSYS
clutterbackendlib -> CLUTTER_WINSYS_LIB
CLUTTER_COGL -> COGL_DRIVER # e.g. "gl"
Note: The CLUTTER_FLAVOUR and CLUTTER_COGL defines are kept for apps
As the first thing to take advantage of the new winsys component in Cogl;
cogl_get_proc_address() has been moved from cogl/{gl,gles}/cogl.c into
cogl/common/cogl.c and this common implementation first trys
_cogl_winsys_get_proc_address() but if that fails then it falls back to
gmodule.
Following bug #1762, the syntax of g-ir-scanner was changed in
gobject-introspection, so Clutter does not build anymore with 0.6.4.
See the bugzilla bug:
http://bugzilla.gnome.org/show_bug.cgi?id=591669
GObject-Introspection now uses a different mechanism to extract the
SONAME when building the gir file and it needs the libtool archive as
option.

Currently, Clutter depends on the internal copy of JSON-GLib for
the ClutterScript parser. This is done to allow building Clutter
on platforms that do not have the library installed on the system.
Just like we use the internal PNG/JPEG loader as a fallback in
case we don't have GdkPixbuf or CoreGraphics available, we should
use the internal copy of JSON-GLib only in case the system copy
is not present.
The change is simply to move the default for the --with-json
configure switch from "internal" to "check".
In order to allow stricter compliance, a third setting should
be present: "system", which fails if the system copy is not
available.
We should also change the introspection generation to avoid
breaking in case we require the installed Json-1.0.gir instead
of the generated ClutterJson.gir
Instead of using a specific function to check whether the X
server supports the XInput extension we can use the generic
Xlib function XQueryExtension(). This cuts down the extra
checks inside the configure.ac and simplifies the code inside
clutter_x11_register_xinput().
HAVE_COGL_GLES2 is defined in config.h through the configure script and
should not be used in public headers.
The patch makes configure generate the right define that can be used
later in the header.
Instead of blacklisting experimental features at the end we can
explicitly mark backends and image backends near their checks and
provide a summary at the end.
Use the AS_COMPILER_FLAGS to check whether the maintainer compiler flags
we use are supported; this should fail gracefully and only use the ones
that the compiler actually understands.

It seems GNU Gold (the new linker) either behaves as if with
--no-undefined by default, or has some issue preventing it from not
doing that when instructed to (I'm not sure if this actually
happens). In any case, clutter uses the Xshm extensions, but does not
link to libXext, which makes gold unhappy.

The XInput support in Clutter is still using XI 1.x. This will never
work correctly, and we are all waiting for XInput 2 anyway. The changes
internally should be minimal, so we can leave everything in place, but
it's better to disable XInput support by default -- at least for the
time being.
Apparently, the XInput extension is using the same pkg-config
file ('xi') for both the 1.x and the 2.x API, so we need to
check for both the 1.x XGetExtensionVersion and the 2.x
XQueryInputVersion.
Clutter copies the gtk-doc from the usual gtk+ template, and
has a version.xml.in containing only:
@VERSION@
Without a newline at the end. Unfortunately, it appears that
autoconf has started adding a newline to the generated version.xml
which then is used as the payload for the "version" XML entity.
Instead of using a secondary file we can make configure generate
the whole clutter-docs.xml and cogl-docs.xml files from a template;
this way we also get the ability to substitute more autoconf variables
into the documentation -- if needs be.
Using --enable-debug, which controls Clutter's debug level, also
defines COGL_ENABLE_DEBUG. This should be left to --enable-cogl-debug
instead, since it's the configure switch that controls COGL debug
level.
Let's try to bring configure.ac into this century, shall we?
* Use the proper shell macros AS_IF and AS_CASE instead of if...fi
and case...esac
* Check for X11 and relative extensions only when building for GLX
and EGLX backends
* Add documentation on the behaviour of binary_age and interface_age
* Coalesce all the common checks to avoid redundancy
* Escape everything that requires escaping
Currently, COGL depends on defining debug symbols by manually
modifying the source code. When it's done, it will forcefully
print stuff to the console.
Since COGL has also a pretty, runtime selectable debugging API
we might as well switch everything to it.
In order for this to happen, configure needs a new:
--enable-cogl-debug
command line switch; this will enable COGL debugging, the
CoglHandle debugging and will also turn on the error checking
for each GL operation.
The default setting for the COGL debug defines is off, since
it slows down the GL operations; enabling it for a particular
debug build is trivial, though.
This update fixes a few issues:
- the use of shave with mingw32 bash on windows,
- fix the unmangling of libtool names
- fix build on solaris
- add an --enable/disable-shave configure option (while still
defaulting to enabled)
COGL should ship its own pkg-config file, obviously still pointing
to Clutter's compiler flags and linking options, for COGL-specific
variables that might be queried at configure time.
For instance, it's easier (and less verbose) to do:
PKG_CHECK_EXISTS([cogl-gl-1.0],
[has_gl_backend=yes],
[has_gl_backend=no])
Than doing:
AC_MSG_CHECKING([for GL support in COGL])
cogl_backend=`$PKG_CONFIG --variable=cogl clutter-0.9`
if test x$cogl_backend = xgl; then
has_gl_backend=yes
AC_MSG_RESULT([found])
else
has_gl_backend=no
AC_MSG_RESULT([not found])
fi
If X11 comes with pkg-config files (like it should) we should not add
those dependencies to the generic BACKEND_PC_FILES variable: that
variable is meant only for backend-specific dependencies handled by
pkg-config -- and Clutter supports non-X11 backends as well.
The X11_PC_FILES variable will only contain X11-related dependencies,
and will be set as part of BACKEND_PC_FILES only inside the GLX and
EGLX backends sections.
Clutter is able to show debug messages written using the CLUTTER_NOTE()
macro at runtime, either by using an environment variable:
CLUTTER_DEBUG=...
or by using a command line switch:
--clutter-debug=...
--clutter-no-debug=...
Both are parsed during the initialization process by using the
GOption API.
COGL would benefit from having the same support.
In order to do this, we need a cogl_get_option_group() function in
COGL that sets up a GOptionGroup for COGL and adds a pre-parse hook
that will check the COGL_DEBUG environment variable. The OptionGroup
will also install two command line switches:
--cogl-debug
--cogl-no-debug
With the same semantics of the Clutter ones.
During Clutter initialization, the COGL option group will be attached
to the GOptionContext used to parse the command line options passed
to a Clutter application.
Every debug message written using:
COGL_NOTE (SECTION, "message format", arguments);
Will then be printed only if SECTION was enabled at runtime.
This whole machinery, like the equivalent one in Clutter, depends on
a compile time switch, COGL_ENABLE_DEBUG, which is enabled at the same
time as CLUTTER_ENABLE_DEBUG. Having two different symbols allows
greater granularity.

The new stable release of gtk-doc provides the --name-space
option for the mkdb utility. This option allows to specify a
namespace for the symbols that will get stripped, so that we
don't get a symbols index containing only "C".
From the homepage (http://dolt.freedesktop.org): Dolt provides a drop-in
replacement for libtool that significantly decreases compile times on
the platforms it supports.
Bug #1453 - Asynchronous texture loading can starve cpu.
Add a mutex that is held in the loader threads during the image
decoding. We were spawning and starting a thread for each asynchronously
loaded texture. This can cause cpu / memory starvation when many pixbuf
loaders allocate their temporary memory at the same time.
Also added -fno-strict-aliasing to MAINTAINER_CFLAGS in configure.ac
to avoid incorrect warnings caused by the static mutex code.
Clutter depends on various libraries, some of them backend-specific
like the X11 libraries.
Whenever possible, we should add those requirements to the pkg-config
file. For this reason, we have a variable inside the configure.ac
template file which should be filled with the backend-specific modules
we check for during configure time, and then added to the standard
list of dependencies that we write inside the clutter.pc file.
The maintainer compiler flags we use trigger warnings and errors
in the autogenerated code that gtk-doc creates to scan the header
and source files. Since we cannot control that, and we must run
a distcheck with both --enable-gtk-doc and --enable-maintainer-flags
turned on, we need to use less-strict compiler flags when inside
the doc/reference subdirectories.
The way to do this is to split the maintainer compiler flags into
their own Makefile variable, called MAINTAINER_CFLAGS. The we
can use $(MAINTAINER_CFLAGS) in the INCLUDES or _CFLAGS sections
of each part of the source directories we wish to check with the
anal retentiveness suited for maintainers.
Clutter has a set of command line options that are added to every
application by means of clutter_init() or by obtaining the Clutter
GOptionGroup and using g_option_context_parse(). Thus, every Clutter
application will automatically have an --help command line switch
showing the list of options and their description.
At the moment, Clutter does not enable localization of the help,
thus making it less than useful on non-English locales.
This patch enables the machinery to create a localization file and
load it when initializing Clutter, by means of the GLib macros and
locale.h API we already use.

The tests have been reorganised into different categories: conformance,
interactive and micro benchmarks.
- conformance tests can be run as part of automated tests
- interactive tests are basically all the existing tests
- micro benchmarks focus on a single performance metric
I converted the timeline tests to conformance tests and also added some
tests from Neil Roberts and Ebassi.
Note: currently only the conformance tests use the glib test APIs,
though the micro benchmarks should too.
The other change is to make the unit tests link into monolithic binaries
which makes the build time for unit tests considerably faster. To deal
with the extra complexity this adds to debugging individual tests I
have added some sugar to the makefiles so all the tests can be run
directly via a symlink and when an individual test is run this way,
then a note is printed to the terminal explaining exactly how that test
may be debugged using GDB.
There is a convenience make rule: 'make test-report', that will run all
the conformance tests and hopefully even open the results in your web
browser. It skips some of the slower timeline tests, but you can run
those using 'make full-report'
