From 989b697ddd46769b0999e8cd16b5ecd393204734 Mon Sep 17 00:00:00 2001 From: Peter Maydell Date: Tue, 26 Feb 2013 17:52:40 +0000 Subject: qemu-log: default to stderr for logging output Switch the default for qemu_log logging output from "/tmp/qemu.log" to stderr. This is an incompatible change in some sense, but logging is mostly used for debugging purposes so it shouldn't affect production use. The previous behaviour can be obtained by adding "-D /tmp/qemu.log" to the command line. This change requires us to: * update all the documentation/help text (we take the opportunity to smooth out minor inconsistencies between the phrasing in linux-user/bsd-user/system help messages) * make linux-user and bsd-user defer to qemu-log for the default logging destination rather than overriding it themselves * ensure that all logfile closing is done via qemu_log_close() and that that function doesn't close stderr as well as the obvious change to the behaviour of do_qemu_set_log() when no logfile name has been specified.
