Author: John Sheu <s...@google.com> Date: Wed Apr 13 13:57:42 2016 -0700 xlib: do not cache return value of glXChooseVisual/glXGetVisualFromFBConfig The returned XVisualInfo from glXChooseVisual/glXGetVisualFromFBConfig is being cached in XMesaVisual.vishandle (and unconditionally overwritten on subsequent calls). However, these entry points are specified to return XVisualInfo instances to be owned by the caller and freed with XFree(), so the return values should not be retained. With this change, XMesaVisual.vishandle is essentially unused and will be removed in a subsequent change. v2: update commit message Reviewed-by: Alejandro PiƱeiro <apinhe...@igalia.com> --- src/mesa/drivers/x11/fakeglx.c | 26 ++++++++------------------ 1 file changed, 8 insertions(+), 18 deletions(-) diff --git a/src/mesa/drivers/x11/fakeglx.c b/src/mesa/drivers/x11/fakeglx.c index 2f4d966..d62d5ab 100644 --- a/src/mesa/drivers/x11/fakeglx.c +++ b/src/mesa/drivers/x11/fakeglx.c @@ -1241,16 +1241,11 @@ Fake_glXChooseVisual( Display *dpy, int screen, int *list ) xmvis = choose_visual(dpy, screen, list, GL_FALSE); if (xmvis) { -#if 0 - return xmvis->vishandle; -#else - /* create a new vishandle - the cached one may be stale */ - xmvis->vishandle = malloc(sizeof(XVisualInfo)); - if (xmvis->vishandle) { - memcpy(xmvis->vishandle, xmvis->visinfo, sizeof(XVisualInfo)); + XVisualInfo* visinfo = malloc(sizeof(XVisualInfo)); + if (visinfo) { + memcpy(visinfo, xmvis->visinfo, sizeof(XVisualInfo)); } - return xmvis->vishandle; -#endif + return visinfo; } else return NULL; @@ -1974,16 +1969,11 @@ Fake_glXGetVisualFromFBConfig( Display *dpy, GLXFBConfig config ) { if (dpy && config) { XMesaVisual xmvis = (XMesaVisual) config; -#if 0 - return xmvis->vishandle; -#else - /* create a new vishandle - the cached one may be stale */ - xmvis->vishandle = malloc(sizeof(XVisualInfo)); - if (xmvis->vishandle) { - memcpy(xmvis->vishandle, xmvis->visinfo, sizeof(XVisualInfo)); + XVisualInfo* visinfo = malloc(sizeof(XVisualInfo)); + if (visinfo) { + memcpy(visinfo, xmvis->visinfo, sizeof(XVisualInfo)); } - return xmvis->vishandle; -#endif + return visinfo; } else { return NULL; _______________________________________________ mesa-commit mailing list mesa-commit@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/mesa-commit
