These events are represented in the form of enumerable messages with a human-readable string representation. Examples of debug events include incorrect use of the GL, warnings of undefined behavior, and performance warnings. A message is uniquely identified by a source, a type and an implementation-dependent ID within the source and type pair. A message's source identifies the origin of the message and can either describe components of the GL, the window system, third-party external sources such as external debuggers, or even the application itself. The type of the message roughly identifies the nature of the event that caused the message. Examples include errors, performance warnings, warnings about undefined behavior or notifications identifying that the application is within a specific section of the application code. A message's ID for a given source and type further distinguishes messages within namespaces. For example, an error caused by a negative parameter value or an invalid internal texture format are both errors generated by the API, but would likely have different message IDs. Each message is also assigned to a severity level that denotes roughly how "important" that message is in comparison to other messages across all sources and types. For example, notification of a GL error would likely have a higher severity than a performance warning due to redundant state changes. Furthermore, every message contains an implementation-dependent string representation that provides a useful description of the event. Messages are communicated to the application through an application- defined callback function that is called by the GL implementation on each debug message. The motivation for the callback routine is to free application developers from actively having to query whether a GL error, or any other debuggable event has happened after each call to a GL function. With a callback, developers can keep their code free of debug checks, set breakpoints in the callback function, and only have to react to messages as they occur. In situations where using a callback is not possible, a message log is also provided that stores only copies of recent messages until they are actively queried. To control the volume of debug output, messages can be disabled either individually by ID, or entire sets of messages can be turned off based on combination of source and type, through the entire application code or only section of the code encapsulated in debug groups. A debug group may also be used to annotate the command stream using descriptive texts. This extension also defines debug markers, a mechanism for the OpenGL application to annotate the command stream with markers for discrete events. When profiling or debugging an OpenGL application with a built-in or an external debugger or profiler, it is difficult to relate the commands within the command stream to the elements of the scene or parts of the program code to which they correspond. Debug markers and debug groups help obviate this by allowing applications to specify this link. For example, a debug marker can be used to identify the beginning of a frame in the command stream and a debug group can encapsulate a specific command stream to identify a rendering pass. Debug groups also allow control of the debug outputs volume per section of an application code providing an effective way to handle the massive amount of debug outputs that drivers can generate. Some existing implementations of ARB_debug_output only expose the ARB_debug_output extension string if the context was created with the debug flag {GLX|WGL}_CONTEXT_DEBUG_BIT_ARB as specified in {GLX|WGL}_ARB_create_context. The behavior is not obvious when the functionality is brought into the OpenGL core specification because the extension string and function entry points must always exist. This extension modifies the existing ARB_debug_output extension to allow implementations to always have an empty message log. The specific messages written to the message log or callback routines are already implementation defined, so this specification simply makes it explicit that it's fine for there to be zero messages generated, even when a GL error occurs, which is useful if the context is non-debug. Debug output can be enabled and disabled by changing the DEBUG_OUTPUT state. It is implementation defined how much debug output is generated if the context was created without the CONTEXT_DEBUG_BIT set. This is a new query bit added to the existing GL_CONTEXT_FLAGS state to specify whether the context was created with debug enabled. Finally, this extension defines a mechanism for OpenGL applications to label their objects (textures, buffers, shaders, etc.) with a descriptive string. When profiling or debugging an OpenGL application within an external or built-in (debut output API) debugger or profiler it is difficult to identify objects from their object names (integers). Even when the object itself is viewed it can be problematic to differentiate between similar objects. Attaching a descriptive string, a label, to an object obviates this difficulty. The intended purpose of this extension is purely to improve the user experience within OpenGL development tools and application built-in profilers and debuggers. This extension typically improves OpenGL programmers efficiency by allowing them to instantly detect issues and the reason for these issues giving him more time to focus on adding new features to an OpenGL application.
