From 4b4971c06fb02df00a2bd20b6b47b5d0e7d799a7 Mon Sep 17 00:00:00 2001 From: Tom Englund Date: Thu, 8 Aug 2024 21:01:50 +0200 Subject: internal: introduce new types to avoid unsigned int rollover and signed int overflow (#7216) * framebuffer: avoid gluint overflow GLuint was being initialized to -1 and rolling over to unsigned int max, its defined behaviour but very unnecessery. add a bool and use it for checking if allocated or not. * opengl: avoid gluint rollover -1 rolls over to unsigned int max, use 0xFF instead. * core: big uint64_t to int type conversion there were a few uint64_t to int implicit conversions overflowing int and causing UB, make all monitor/workspaces/windows use the new typedefs. also fix the various related 64 to 32 implicit conversions going around found with -Wshorten-64-to-32 --- src/render/Framebuffer.hpp | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'src/render/Framebuffer.hpp') diff --git a/src/render/Framebuffer.hpp b/src/render/Framebuffer.hpp index a46a4859..ca7f9e8a 100644 --- a/src/render/Framebuffer.hpp +++ b/src/render/Framebuffer.hpp @@ -18,7 +18,8 @@ class CFramebuffer { Vector2D m_vSize; SP m_cTex; - GLuint m_iFb = -1; + GLuint m_iFb; + bool m_iFbAllocated{false}; SP m_pStencilTex; }; \ No newline at end of file -- cgit v1.2.3
