Title:
xvfb-run munges stdout and stderr together
Status in “xorg-server” package in Ubuntu:
Confirmed
Bug description:
It executes the supplied command thusly:
DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@" 2>&1
This should be
DISPLAY=:$SERVERNUM XAUTHORITY=$AUTHFILE "$@"
Leaving the caller to redirect stderr to stdout, or to supply a single
fd at their discretion. The side effect of munging the two fd's
together is that programs which provide structured data on stdout have
their output streams corrupted if they, or any subprocesses they have,
happen to write to stderr at an inopportune time.
