* Build a .xz file on release instead of a .bzip2 fileNeil Roberts2013-09-231-1/+1
| | | | | | | | | | | Previously when we released a .bzip2 file the Gnome release scripts will just convert this to a .xz file and generate its own checksum. The .bzip2 is never actually available on the FTP server. This isn't ideal because we were listing the checksum of the .bzip2 file in the release message but that is useless information. This patch changes it to generate a .xz file instead which is also what Clutter does. Reviewed-by: Robert Bragg <robert@linux.intel.com>

* Separate out CoglPath api into sub-libraryRobert Bragg2013-06-121-4/+24
| | | | | | | | | | | | | | | | | | | | | | | This splits out the cogl_path_ api into a separate cogl-path sub-library like cogl-pango and cogl-gst. This enables developers to build Cogl with this sub-library disabled if they don't need it which can be useful when its important to keep the size of an application and its dependencies down to a minimum. The functions cogl_framebuffer_{fill,stroke}_path have been renamed to cogl_path_{fill,stroke}. There were a few places in core cogl and cogl-gst that referenced the CoglPath api and these have been decoupled by using the CoglPrimitive api instead. In the case of cogl_framebuffer_push_path_clip() the core clip stack no longer accepts path clips directly but it's now possible to get a CoglPrimitive for the fill of a path and so the implementation of cogl_framebuffer_push_path_clip() now lives in cogl-path and works as a shim that first gets a CoglPrimitive and uses cogl_framebuffer_push_primitive_clip instead. We may want to consider renaming cogl_framebuffer_push_path_clip to put it in the cogl_path_ namespace. Reviewed-by: Neil Roberts <neil@linux.intel.com>
* tests: Adds our first white-box unit testRobert Bragg2013-06-061-2/+16
| | | | | | | | | | | | | | | | | | This adds a white-box unit test that verifies that GL_BLEND is disabled when drawing an opaque rectangle, enabled when drawing a transparent rectangle and then disabled again when drawing a transparent rectangle but with a blend string that effectively disables blending. This shares the test utilities and launcher infrastructure we are using for conformance tests so we get consistent reporting and so unit tests will be run against a range of different drivers. This adds a --enable-unit-tests configure option which is enabled by default but if disabled will make all UNIT_TESTS() into static inline functions that we should expect the compiler to discard since they won't be referenced by anything.

* Adds initial Emscripten support to CoglRobert Bragg2013-05-291-93/+179
| | | | | | | | | | | | | | | | | | This enables basic Emscripten support in Cogl via the SDL winsys. Assuming you have setup an emscripten toolchain you can configure Cogl like this: emconfigure ./configure --enable-debug --enable-emscripten Building the examples will build .html files that can be loaded directly by a WebGL enabled browser. Note: at this point the emscripten support has just barely been smoke tested so it's expected that as we continue to build on this we will learn about more things we need to change in Cogl to full support this environment.

One thing that I wasn't able to figure out with this was how to get the documentation to have correct references to the main Cogl docs.

* cogland: Update to the Wayland 1.0 APINeil Roberts2013-03-211-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This updates Cogland example compositor to use the stable Wayland 1.0 API. • When the client attaches a new buffer to a surface it is now added to a struct contaning pending the state instead of immediately switching to the new buffer. This state is then flushed when the surface is committed. • The frame callbacks are now queued in a pending list and only added to the compositor's main list when the surface is committed. Both lists are now a wl_list instead of a GQueue because it makes it easier to remove the callback without knowing which list it is in. • When the buffer is destroyed for a surface the resource for the buffer is now sent a release event. • It now flushes the clients in the prepare for the for the Wayland event GSource. This is part of the multi-threaded API in this Wayland patch: http://cgit.freedesktop.org/wayland/wayland/commit/?id=53d24713a31d59 • Implements a dummy wl_region interface. The only interfaces that actually use regions (the opaque and input regions) are ignored but we need the interface to create a resource. • Most the of the SHM interface is now implemented directly in libwayland-server except that it still needs to copy the data to the subregion of the texture when the damage region is committed. • The callback list for when a resource is destroyed has been unified into a generic wl_signal implementation so the signature for the functions has been changed. http://cgit.freedesktop.org/wayland/wayland/commit/?h=6802eaa68af9022 • The wl_buffer struct no longer has a user_data parameter so we can't attach our own CoglandBuffer data to it. Instead the CoglandSurface now just keeps track of the wl_buffer directly. • The Cogland example is now unconditionally built instead of checking the Wayland version number in the configure script. It looks like this check was broken anyway because it was checking the version of the gbm package rather than a Wayland package. Reviewed-by: Robert Bragg <robert@linux.intel.com>
* cogl-gst: remove experimental "HW Decode" codeRobert Bragg2013-03-211-7/+0
| | | | | | | | | | | | | | The experimental HW decode path was adapted from clutter-gst based on some experimental gstreamer api. This path was disabled by upstream gstreamer developers back in september last year due to instabilities. Without understanding how the experimental api is implemented it seems rather strange to be plucking out the GL handle of a cogl texture and passing that to some unknown gstreamer code which would presumably somehow have to use the same GL context as Cogl to be able to do something with that texture. For now we can strip all of this unused code and it would be easy enough to re-instate later if it's useful. Reviewed-by: Neil Roberts <neil@linux.intel.com>

* Fixes for --disable-glibNeil Roberts2012-11-261-0/+3
| | | | | | | | | | | | | | | | | | | | | | This fixes some problems which were stopping --disable-glib from working properly: • A lot of the public headers were including glib.h. This shouldn't be necessary because the API doesn't expose any glib types. Otherwise any apps would require glib in order to get the header. • The public headers were using G_BEGIN_DECLS. There is now a replacement macro called COGL_BEGIN_DECLS which is defined in cogl-types.h. • A similar fix has been done for G_GNUC_NULL_TERMINATED and G_GNUC_DEPRECATED. • The CFLAGS were not including $(builddir)/deps/glib which was preventing it finding the generated glibconfig.h when building out of tree.

* configure: Don't allow --enable-gdk-pixbuf with --disable-glibNeil Roberts2012-11-261-71/+70
| | | | | | | | | | | | | | | | | | | | | | The GDK pixbuf support requires being able to propagate errors from GDKPixbuf as GErrors. This won't work if we are using the builtin version of GLib because any attempt to call g_error_free from within Cogl will use the internal version which will free the error using the wrong slice allocator. It probably doesn't make much sense to build without glib but with gdk-pixbuf so there's not much point in trying to work around this situation. Previously if you specified --enable-gdk-pixbuf but gdk-pixbuf was not available it would silently disable it. This pach also fixes it so that it will report an error in that case. If --enable-gdk-pixbuf is not specified it will now default to enabling it only if both glib is enabled and gdk-pixbuf is available. This patch looks slightly longer than it ought to be because it moves the check for glib up to above the descisions about the image backend. Reviewed-by: Robert Bragg <robert@linux.intel.com>

* Add an SDL2 winsysNeil Roberts2012-06-201-1/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | This adds an alternate version of the SDL winsys using the SDL 2 API. The two versions are mutually exclusive and share the same CoglWinsysID. Version 2 of SDL fits a little bit better with Cogl because it supports multiple windows and the video subsystem can be initialised entirely independently of the rest of the subsystems. The SDL2 winsys creates an invisible dummy window in order to bind the GL context after creating the Cogl display. This is similar to how the X11 winsys's work. SDL2 seems to support compiling with support for both GL and GLES. However there doesn't seem to be a way to select between the two backends outside of SDL. In fact if you do compile them both in it seems to break down because it will always try to use the window system functions from the GLES backend because those are filled in second in the vtable. However when creating the window it will always prefer to use the GL function to choose a visual. This function gets confused because the GL backend has not been initialised at that point. The Cogl backend therefore just leaves it up to SDL to pick a sensible backend. It will then verify that it picked a GL library which matches the Cogl driver by checking the string from glGetString(GL_VERSION). Reviewed-by: Robert Bragg <robert@linux.intel.com>
