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/protocols/ForeignToplevelWlr.cpp | 2 +- src/protocols/ForeignToplevelWlr.hpp | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) (limited to 'src/protocols') diff --git a/src/protocols/ForeignToplevelWlr.cpp b/src/protocols/ForeignToplevelWlr.cpp index 295834ea..b31a4083 100644 --- a/src/protocols/ForeignToplevelWlr.cpp +++ b/src/protocols/ForeignToplevelWlr.cpp @@ -119,7 +119,7 @@ wl_resource* CForeignToplevelHandleWlr::res() { } void CForeignToplevelHandleWlr::sendMonitor(CMonitor* pMonitor) { - if (lastMonitorID == (int64_t)pMonitor->ID) + if (lastMonitorID == pMonitor->ID) return; const auto CLIENT = resource->client(); diff --git a/src/protocols/ForeignToplevelWlr.hpp b/src/protocols/ForeignToplevelWlr.hpp index e3b6f3f3..99f63b47 100644 --- a/src/protocols/ForeignToplevelWlr.hpp +++ b/src/protocols/ForeignToplevelWlr.hpp @@ -20,7 +20,7 @@ class CForeignToplevelHandleWlr { SP resource; PHLWINDOWREF pWindow; bool closed = false; - int64_t lastMonitorID = -1; + MONITORID lastMonitorID = MONITOR_INVALID; void sendMonitor(CMonitor* pMonitor); void sendState(); -- cgit v1.2.3
