Without that you don't see error output from dot or convert, and that makes it impossible to debug anything. If I want a direct forwarding of the bytes, how should I do this in python? Capturing stderr and then re-dumping it is kinda silly ... Note that I copied this pattern from the kernel-doc extension, seems to have worked there. -Daniel -- Daniel Vetter Software Engineer, Intel Corporation http://blog.ffwll.ch _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
