Add runtime debug messages for COGL 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.

cogl debug: Makes COGL_DEBUG=all|verbose|help more useful COGL_DEBUG=all wasn't previously useful as there are several options that change the behaviour of Cogl and all together wouldn't help anyone debug anything. This patch makes it so COGL_DEBUG=all|verbose now only enables options that don't change the behaviour of Cogl, i.e. they only affect the amount of noise we'll print to a terminal. In addition to that this patch also improves the output from COGL_DEBUG=help so we now print a table of options including one liner descriptions of what each option enables.

Add internal _cogl_init() function This adds a _cogl_init function for Cogl that we expect to be the first thing called before anything else is done with Cogl. It's not a public API so it's expected that all entry points for Cogl that might be the first function used should call _cogl_init(). We currently call _cogl_init() in these functions: cogl_renderer_new cogl_display_new cogl_context_new cogl_android_set_native_window _cogl_init() can be called multiple times, and only the first call has any affect. For example _cogl_init() gives us a place check and parse the COGL_DEBUG environment variable. Since we don't have any need to parse command line arguments (we can always get user configuration options from the environment) our init function doesn't require argc/argv pointers. By saying up front that we aren't interested in command line arguments that means we can avoid the mess that is GOption based library initialization which is extremely fragile due to its lack of dependency tracking between modules.

Add -Wmissing-declarations to maintainer flags and fix problems This option to GCC makes it give a warning whenever a global function is defined without a declaration. This should catch cases were we've defined a function but forgot to put it in a header. In that case it is either only used within one file so we should make it static or we should declare it in a header. The following changes where made to fix problems: • Some functions were made static • cogl-path.h (the one containing the 1.0 API) was split into two files, one defining the functions and one defining the enums so that cogl-path.c can include the enum and function declarations from the 2.0 API as well as the function declarations from the 1.0 API. • cogl2-clip-state has been removed. This only had one experimental function called cogl_clip_push_from_path but as this is unstable we might as well remove it favour of the equivalent cogl_framebuffer_* API. • The GLX, SDL and WGL winsys's now have a private header to define their get_vtable function instead of directly declaring in the C file where it is called. • All places that were calling COGL_OBJECT_DEFINE need to have the cogl_is_whatever function declared so these have been added either as a public function or in a private header. • Some files that were not including the header containing their function declarations have been fixed to do so. • Any unused error quark functions have been removed. If we later want them we should add them back one by one and add a declaration for them in a header. • _cogl_is_framebuffer has been renamed to cogl_is_framebuffer and made a public function with a declaration in cogl-framebuffer.h • Similarly for CoglOnscreen. • cogl_vdraw_indexed_attributes is called cogl_framebuffer_vdraw_indexed_attributes in the header. The definition has been changed to match the header. • cogl_index_buffer_allocate has been removed. This had no declaration and I'm not sure what it's supposed to do. • CoglJournal has been changed to use the internal CoglObject macro so that it won't define an exported cogl_is_journal symbol. • The _cogl_blah_pointer_from_handle functions have been removed. CoglHandle isn't used much anymore anyway and in the few places where it is used I think it's safe to just use the implicit cast from void* to the right type. • The test-utils.h header for the conformance tests explicitly disables the -Wmissing-declaration option using a pragma because all of the tests declare their main function without a header. Any mistakes relating to missing declarations aren't really important for the tests. • cogl_quaternion_init_from_quaternion and init_from_matrix have been given declarations in cogl-quaternion.h Reviewed-by: Robert Bragg <robert@linux.intel.com>

Removes all remaining use of CoglHandle Removing CoglHandle has been an on going goal for quite a long time now and finally this patch removes the last remaining uses of the CoglHandle type and the cogl_handle_ apis. Since the big remaining users of CoglHandle were the cogl_program_ and cogl_shader_ apis which have replaced with the CoglSnippets api this patch removes both of these apis. Reviewed-by: Neil Roberts <neil@linux.intel.com> (cherry picked from commit 6ed3aaf4be21d605a1ed3176b3ea825933f85cf0) Since the original patch was done after removing deprecated API this back ported patch doesn't affect deprecated API and so actually this cherry-pick doesn't remove all remaining use of CoglHandle as it did for the master branch of Cogl.

[cogl] Add a PANGO debug flag for CoglPango use The CoglPango code falls under the COGL "jurisdiction"; this means that it cannot include Clutter headers unless strictly necessary. The CoglPangoRenderer code was using the CLUTTER_NOTE() macro. Now that COGL has it's own COGL_NOTE() similar macro, CoglPango should use that and avoid including clutter-debug.h (which pulls in clutter-private.h which in turn pulls in clutter-actor.h). A new flag, COGL_DEBUG_PANGO, has been added to the COGL debug flags.

The outline colors rotate in order from red to green to blue which can also help confirm the order that your geometry really drawn. The outlines are not affected by the current material state, so if you e.g. have a blending bug where geometry mysteriously disappears this can confirm if the underlying rectangles are actually being emitted but blending is causing them to be invisible.

Add a CoglTexturePixmapX11 texture backend This is a publicly exposed texture backend to create a texture which contains the contents of an X11 pixmap. The API is currently marked as experimental. The backend internally holds a handle to another texture. All of the backend virtuals simply redirect to the internal texture. The texture can optionally be automatically updated if the automatic_updates parameter is TRUE. If set then Cogl will listen for damage events on the pixmap and update the texture accordingly. Alternatively a damage object can be created externally and passed down to Cogl. The updates can be performed with XGetImage, XShmGetImage or the GLX_EXT_texture_pixmap extension. If the TFP extension is used it will optionally try to create a rectangle texture if the driver does not support NPOTs or it is forced through the COGL_PIXMAP_TEXTURE_RECTANGLE or CLUTTER_PIXMAP_TEXTURE_RECTANGLE environment variables. If the GLXFBConfig does not support mipmapping then it will fallback to using X{Shm,}GetImage. It keeps a separate texture around for this so that it can later start using the TFP texture again if the texture is later drawn with mipmaps disabled.

[cogl] Move debugging to a configure-time switch 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.

material: Adds backend abstraction for fragment processing As part of an effort to improve the architecture of CoglMaterial internally this overhauls how we flush layer state to OpenGL by adding a formal backend abstraction for fragment processing and further formalizing the CoglTextureUnit abstraction. There are three backends: "glsl", "arbfp" and "fixed". The fixed backend uses the OpenGL fixed function APIs to setup the fragment processing, the arbfp backend uses code generation to handle fragment processing using an ARBfp program, and the GLSL backend is currently only there as a formality to handle user programs associated with a material. (i.e. the glsl backend doesn't yet support code generation) The GLSL backend has highest precedence, then arbfp and finally the fixed. If a backend can't support some particular CoglMaterial feature then it will fallback to the next backend. This adds three new COGL_DEBUG options: * "disable-texturing" as expected should disable all texturing * "disable-arbfp" always make the arbfp backend fallback * "disable-glsl" always make the glsl backend fallback * "show-source" show code generated by the arbfp/glsl backends

CoglMaterial: Implements sparse materials design This is a complete overhaul of the data structures used to manage CoglMaterial state. We have these requirements that were aiming to meet: (Note: the references to "renderlists" correspond to the effort to support scenegraph level shuffling of Clutter actor primitives so we can minimize GPU state changes) Sparse State: We wanted a design that allows sparse descriptions of state so it scales well as we make CoglMaterial responsible for more and more state. It needs to scale well in terms of memory usage and the cost of operations we need to apply to materials such as comparing, copying and flushing their state. I.e. we would rather have these things scale by the number of real changes a material represents not by how much overall state CoglMaterial becomes responsible for. Cheap Copies: As we add support for renderlists in Clutter we will need to be able to get an immutable handle for a given material's current state so that we can retain a record of a primitive with its associated material without worrying that changes to the original material will invalidate that record. No more flush override options: We want to get rid of the flush overrides mechanism we currently use to deal with texture fallbacks, wrap mode changes and to handle the use of highlevel CoglTextures that need to be resolved into lowlevel textures before flushing the material state. The flush options structure has been expanding in size and the structure is logged with every journal entry so it is not an approach that scales well at all. It also makes flushing material state that much more complex. Weak Materials: Again for renderlists we need a way to create materials derived from other materials but without the strict requirement that modifications to the original material wont affect the derived ("weak") material. The only requirement is that its possible to later check if the original material has been changed. A summary of the new design: A CoglMaterial now basically represents a diff against its parent. Each material has a single parent and a mask of state that it changes. Each group of state (such as the blending state) has an "authority" which is found by walking up from a given material through its ancestors checking the difference mask until a match for that group is found. There is only one root node to the graph of all materials, which is the default material first created when Cogl is being initialized. All the groups of state are divided into two types, such that infrequently changed state belongs in a separate "BigState" structure that is only allocated and attached to a material when necessary. CoglMaterialLayers are another sparse structure. Like CoglMaterials they represent a diff against their parent and all the layers are part of another graph with the "default_layer_0" layer being the root node that Cogl creates during initialization. Copying a material is now basically just a case of slice allocating a CoglMaterial, setting the parent to be the source being copied and zeroing the mask of changes. Flush overrides should now be handled by simply relying on the cheapness of copying a material and making changes to it. (This will be done in a follow on commit) Weak material support will be added in a follow on commit.

This uses _cogl_pipeline_hash and _cogl_pipeline_equal to hash and compare the keys for the cache. There is a new COGL_DEBUG=disable-program-caches option that can disable the cache for debugging purposes.

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.

Options specified in the user config file have priority over the system config options. The config file has an .ini style syntax with a mandatory [global] section and we currently understand 3 keynames: COGL_DEBUG, COGL_DRIVER and COGL_RENDERER which have the same semantics as the corresponding environment variables. Options set using the environment variables have priority over options set in the config files. To allow users to undo the enabling of debug options in config files this patch also adds a check for COGL_NO_DEBUG environment variable which will disable the specified options which may have been enabled in config files.

Add internal _cogl_init() function This adds a _cogl_init function for Cogl that we expect to be the first thing called before anything else is done with Cogl. It's not a public API so it's expected that all entry points for Cogl that might be the first function used should call _cogl_init(). We currently call _cogl_init() in these functions: cogl_renderer_new cogl_display_new cogl_context_new cogl_android_set_native_window _cogl_init() can be called multiple times, and only the first call has any affect. For example _cogl_init() gives us a place check and parse the COGL_DEBUG environment variable. Since we don't have any need to parse command line arguments (we can always get user configuration options from the environment) our init function doesn't require argc/argv pointers. By saying up front that we aren't interested in command line arguments that means we can avoid the mess that is GOption based library initialization which is extremely fragile due to its lack of dependency tracking between modules.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead.

cogl_arg_no_debug_cb (const char *key,
cogl: improves header and coding style consistency We've had complaints that our Cogl code/headers are a bit "special" so this is a first pass at tidying things up by giving them some consistency. These changes are all consistent with how new code in Cogl is being written, but the style isn't consistently applied across all code yet. There are two parts to this patch; but since each one required a large amount of effort to maintain tidy indenting it made sense to combine the changes to reduce the time spent re indenting the same lines. The first change is to use a consistent style for declaring function prototypes in headers. Cogl headers now consistently use this style for prototypes: return_type cogl_function_name (CoglType arg0, CoglType arg1); Not everyone likes this style, but it seems that most of the currently active Cogl developers agree on it. The second change is to constrain the use of redundant glib data types in Cogl. Uses of gint, guint, gfloat, glong, gulong and gchar have all been replaced with int, unsigned int, float, long, unsigned long and char respectively. When talking about pixel data; use of guchar has been replaced with guint8, otherwise unsigned char can be used. The glib types that we continue to use for portability are gboolean, gint{8,16,32,64}, guint{8,16,32,64} and gsize. The general intention is that Cogl should look palatable to the widest range of C programmers including those outside the Gnome community so - especially for the public API - we want to minimize the number of foreign looking typedefs.

Add internal _cogl_init() function This adds a _cogl_init function for Cogl that we expect to be the first thing called before anything else is done with Cogl. It's not a public API so it's expected that all entry points for Cogl that might be the first function used should call _cogl_init(). We currently call _cogl_init() in these functions: cogl_renderer_new cogl_display_new cogl_context_new cogl_android_set_native_window _cogl_init() can be called multiple times, and only the first call has any affect. For example _cogl_init() gives us a place check and parse the COGL_DEBUG environment variable. Since we don't have any need to parse command line arguments (we can always get user configuration options from the environment) our init function doesn't require argc/argv pointers. By saying up front that we aren't interested in command line arguments that means we can avoid the mess that is GOption based library initialization which is extremely fragile due to its lack of dependency tracking between modules.

Add runtime debug messages for COGL 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.

cogl-debug: Split the flags to support more than 32 The CoglDebugFlags are now stored in an array of unsigned ints rather than a single variable. The flags are accessed using macros instead of directly peeking at the cogl_debug_flags variable. The index values are stored in the enum rather than the actual mask values so that the enum doesn't need to be more than 32 bits wide. The hope is that the code to determine the index into the array can be optimized out by the compiler so it should have exactly the same performance as the old code.

cogl: Add support for reading a cogl.conf config file When cogl initializes we now check for a cogl/cogl.conf in any of the system config dirs (determined using $XDG_CONFIG_DIRS on linux) we then also check the user's config directory (determined using XDG_CONFIG_HOME on linux) for a cogl/cogl.conf file. Options specified in the user config file have priority over the system config options. The config file has an .ini style syntax with a mandatory [global] section and we currently understand 3 keynames: COGL_DEBUG, COGL_DRIVER and COGL_RENDERER which have the same semantics as the corresponding environment variables. Options set using the environment variables have priority over options set in the config files. To allow users to undo the enabling of debug options in config files this patch also adds a check for COGL_NO_DEBUG environment variable which will disable the specified options which may have been enabled in config files.

Switch use of primitive glib types to c99 equivalents The coding style has for a long time said to avoid using redundant glib data types such as gint or gchar etc because we feel that they make the code look unnecessarily foreign to developers coming from outside of the Gnome developer community. Note: When we tried to find the historical rationale for the types we just found that they were apparently only added for consistent syntax highlighting which didn't seem that compelling. Up until now we have been continuing to use some of the platform specific type such as gint{8,16,32,64} and gsize but this patch switches us over to using the standard c99 equivalents instead so we can further ensure that our code looks familiar to the widest range of C developers who might potentially contribute to Cogl. So instead of using the gint{8,16,32,64} and guint{8,16,32,64} types this switches all Cogl code to instead use the int{8,16,32,64}_t and uint{8,16,32,64}_t c99 types instead. Instead of gsize we now use size_t For now we are not going to use the c99 _Bool type and instead we have introduced a new CoglBool type to use instead of gboolean.
