  "message": "dex2oat: Avoid an open from /proc/self/fd\n\nReadCommentedInputStream reads a text file by line, filters out empty or\ncommented line, then send the line to a callback. The original\nimplementation uses ifstream and std::getline.\n\naosp/1734115 added a way to read the text file by FD. Since there\ndoesn\u0027t seem to be a way in C++ to convert the FD to an input stream,\nit creates one by opening /proc/self/fd/43.\n\nIn the context of Comp OS, this requires giving dex2oat a special open\nprivilege to \"authfs\".\n\nThis change replaces ifstream/std::getline with f(d)open/getline(3).\n\nBug: 196404749\nTest: TH\nTest: Disallow open for dex2oat in microdroid, ComposHostTestCases still\n      pass\nIgnore-AOSP-First: merge conflict resolution\nChange-Id: I257f471b2afc80b6f1e1f8fa25248abc7ff5a3d5\n(cherry picked from commit b81cc515d96f38286662e470bc38a0f6bb12ea57)\n",
