OpenGL Leak原理

2

Matrix中有针对open gl泄露的检测，针对最新代码进行了研究，没有特别理解背后的原理，有几个问题希望能够解答一下，或者提供一下相应的资料 ### OpenglIndexDetectorService作用 在OpenglLeakPlugin的start方法中，在开启的Thread中调用了startImpl方法，随后启动了OpenglIndexDetectorService，Service中的onBind返回了一个IBinder对象，为何要跨进程？在Service中的onServiceConnected中进行了hook操作，这样做的原因是什么，为什么不直接hook？ ### get_gl_hooks作用 以Java_com_tencent_matrix_openglleak_hook_OpenGLHook_hookGlGenTextures这个方法为例 `extern "C" JNIEXPORT jboolean JNICALL Java_com_tencent_matrix_openglleak_hook_OpenGLHook_hookGlGenTextures (JNIEnv *, jclass, jint index) { gl_hooks_t *hooks = get_gl_hooks(); if (NULL == hooks) { return...
