The tests check the existence of objects as 57 reported by the Is* family of GL functions, the state of bindings as 58 reported in various state variables, and the behavior of containers with 59 deleted objects. 60 61 NOTE: Because these tests try to delete objects that are directly or 62 indirectly attached to the current context, a faulty OpenGL ES 63 implementation may reclaim and later reallocate memory that is still 64 being referenced. This may result in unpredictable errors at some later 65 time. Use of external memory debugging tools may be required to 66 accurately identify these errors. 67 68 The "gen.*" test cases call the object type's Gen* or Create* function 69 to allocate a new name, and then check whether the name is used, i.e. 70 whether a new object was created for the name (as reported by the result 71 of the corresponding Is* function). In OpenGL ES 3.0, the Create* 72 functions and the GenSamplers function must always create an object, and 73 the other Gen* functions must never create an object. 74 75 The "delete.*" test cases call an object type's Gen* or Create* function 76 followed by the Delete* function. They then check that the generated 77 name is no longer in use. 78 79 The "bind.*" test cases call an object type's Gen* function followed by 80 its Bind* function. They then check that the name is in use. 81 82 The "delete_bound.*" test cases call an object type's Gen* function 83 followed by its Bind* function and Delete* function. They then check 84 that the name is no longer in use and that the binding has been removed. 85 86 The "bind_no_gen.*" test cases call the object type's Bind* function for 87 a random name that has not been produced by the Gen* function. They then 88 check whether the function call succeeded. In OpenGL ES 3.0, the 89 BindBuffer, BindFramebuffer, BindRenderbuffer and BindTexture functions 90 must succeed for arbitrary object names, and the other Bind* functions 91 must fail. 92 93 The "delete_used.program" test case creates a new program object (along 94 with associated shader objects) and makes it the current program with 95 the glUseProgram function. The program object is then deleted. The test 96 checks that the name of the program remains in use and is flagged for 97 deletion. Then the program is made non-current and the test checks that 98 the name becomes unused. 99 100 The "delete_active.transform_feedback" test case creates a new transform 101 feedback object, makes it active with the BeginTransformFeedback 102 function, and then attempts to delete it. The test checks that the 103 deletion fails. 104 105 The "attach.*" family of test cases create a container object (a 106 framebuffer, vertex array, transform feedback, or program) and attach 107 another object (a texture, renderbuffer, buffer or shader) to it. The 108 attached object is then deleted. 109 110 In the "attach.deleted_name.*" test cases, the container is queried for 111 its attachment, and the existence of the deleted attachment object is 112 checked. In OpenGL ES 3.0, shader objects must exist even after deletion 113 if they are attached to a program. 114 115 In the "attach.deleted_input.*" test cases, the container is read from 116 (by reading a framebuffer's pixel contents or using a program or vertex 117 array for drawing) first before the attachment is deleted, and then 118 again after deleting the attachment and creating a new object of the 119 attachment type. If the results differ, the new object erroneously 120 affected the container's state. 121 122 In the "attach.deleted_output.*" test cases, the container is written to 123 (by drawing to a framebuffer or by using a transform feedback) first 124 after deleting the attachment and then again after creating a new object 125 of the attachment type. If the writing affected the new object state, it 126 erroneously shared state with the deleted attachment. 127
