From 7d25ed70362ee9362aeeadb00f5a4e2bea690827 Mon Sep 17 00:00:00 2001 From: Stefan Dirsch Date: Mon, 25 Apr 2016 15:06:25 +0200 Subject: [PATCH] dri3: Check for dummyContext to see if the glx_context is valid According to the comments in src/glx/glxcurrent.c __glXGetCurrentContext() always returns a valid pointer. If no context is made current, it will contain dummyContext. Thus a test for NULL will always fail. https://lists.freedesktop.org/archives/mesa-dev/2016-April/113962.html Signed-off-by: Stefan Dirsch Reviewed-by: Egbert Eich Reviewed-by: Emil Velikov --- src/glx/dri3_glx.c | 8 ++------ 1 file changed, 2 insertions(+), 6 deletions(-) diff --git a/src/glx/dri3_glx.c b/src/glx/dri3_glx.c index 6729357..90d7bba 100644 --- a/src/glx/dri3_glx.c +++ b/src/glx/dri3_glx.c @@ -127,13 +127,9 @@ static __DRIcontext * glx_dri3_get_dri_context(struct loader_dri3_drawable *draw) { struct glx_context *gc = __glXGetCurrentContext(); + struct dri3_context *dri3Ctx = (struct dri3_context *) gc; - if (gc) { - struct dri3_context *dri3Ctx = (struct dri3_context *) gc; - return dri3Ctx->driContext; - } - - return NULL; + return (gc != &dummyContext) ? dri3Ctx->driContext : NULL; } static void -- 2.7.4
