From 77506dac8e81e9548a7e9680ce367175fe5747af Mon Sep 17 00:00:00 2001 From: Dave Airlie Date: Thu, 11 Jun 2009 10:50:32 +1000 Subject: [PATCH] GLX: attempt to fix glean makeCurrent test cases. Two parts to this: One we don't keep pointers to possibly freed memory anymore once we unbind the drawables from the context. Brian I need to figure out what the comment you made there, can we get a glean/piglit test so we can fix it properly? If the new gc is the same as the oldGC, we call the unbind even though we just bound it in that function. doh. --- src/glx/x11/glxcurrent.c | 2 +- src/mesa/drivers/dri/common/dri_util.c | 6 +++++- 2 files changed, 6 insertions(+), 2 deletions(-) diff --git a/src/glx/x11/glxcurrent.c b/src/glx/x11/glxcurrent.c index 01f42332413..d44e0dd1fc8 100644 --- a/src/glx/x11/glxcurrent.c +++ b/src/glx/x11/glxcurrent.c @@ -457,7 +457,7 @@ MakeContextCurrent(Display * dpy, GLXDrawable draw, &dummy_reply); } #ifdef GLX_DIRECT_RENDERING - else if (oldGC->driContext) { + else if (oldGC->driContext && oldGC != gc) { oldGC->driContext->unbindContext(oldGC->driContext); } #endif diff --git a/src/mesa/drivers/dri/common/dri_util.c b/src/mesa/drivers/dri/common/dri_util.c index ae0e61e515b..2b1493a6ded 100644 --- a/src/mesa/drivers/dri/common/dri_util.c +++ b/src/mesa/drivers/dri/common/dri_util.c @@ -122,6 +122,9 @@ static int driUnbindContext(__DRIcontext *pcp) pdp = pcp->driDrawablePriv; prp = pcp->driReadablePriv; + /* already unbound */ + if (!pdp && !prp) + return GL_TRUE; /* Let driver unbind drawable from context */ (*psp->DriverAPI.UnbindContext)(pcp); @@ -146,9 +149,10 @@ static int driUnbindContext(__DRIcontext *pcp) * window we can determine the last context bound to the window and * use that context's lock.
