Overview
41

42
    This extension allows the user to control the behaviour when binding an
43
    object that has not been generated.  This functionality is useful to
44
    notify the user of potential use-after-free errors or support other APIs
45
    such as WebGL on top of an OpenGL ES context.

Additions to the OpenGL ES Specification
59

60
    Add to the end of Section 2.9 "Buffer Objects":
61

62
    If BIND_GENERATES_RESOURCE_CHROMIUM is false, BindBuffer fails and an
63
    INVALID_OPERATION error is generated if buffer is not zero or a name
64
    returned from a previous call to GenBuffers, or if such a name has since
65
    been deleted with DeleteBuffers.
66

67
    Add to the end of Section 3.7.13 "Texture Objects":
68

69
    If BIND_GENERATES_RESOURCE_CHROMIUM is false, BindTexture fails and an
70
    INVALID_OPERATION error is generated if texture is not zero or a name
71
    returned from a previous call to GenTextures, or if such a name has since
72
    been deleted with DeleteTextures.
73

74
    Add to the end of Section 4.4.1 "Binding and Managing Framebuffer Objects":
75

76
    If BIND_GENERATES_RESOURCE_CHROMIUM is false, BindFramebuffer fails and an
77
    INVALID_OPERATION error is generated if framebuffer is not zero or a name
78
    returned from a previous call to GenFramebuffers, or if such a name has
79
    since been deleted with DeleteFramebuffers.
80

81
    Add to the end of Section 4.4.3 "Renderbuffer Objects":
82

83
    If BIND_GENERATES_RESOURCE_CHROMIUM is false, BindRenderbuffer fails and an
84
    INVALID_OPERATION error is generated if renderbuffer is not zero or a name
85
    returned from a previous call to GenRenderbuffers, or if such a name has
86
    since been deleted with DeleteRenderbuffers.

Issues
105

106
    (1) Should the BIND_GENERATES_RESOURCE_CHROMIUM state be enabled at context
107
        creation time or dynamically through the Enable and Disable functions?
108

109
    RESOLOVED: BIND_GENERATES_RESOURCE_CHROMIUM is initialized by a context
110
    creation attribute and cannot be modified.  One of the major use cases of
111
    this extension is to back WebGL contexts and the end user should not be
112
    allowed to modify this state.
