* readline: avoid memcpy() of overlapping regionsNickolai Zeldovich2013-01-081-2/+2
| | | | | | | | | | | memcpy() for overlapping regions is undefined behavior; use memmove() instead in readline_hist_add(). [Keep tab characters since surrounding code still uses them -- Stefan] Signed-off-by: Nickolai Zeldovich <nickolai@csail.mit.edu> Reviewed-by: Richard Henderson <rth@twiddle.net> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

* monitor: Fix memory leak with readline completionStefan Weil2012-06-111-0/+3
| | | | | | | | | | Each string which is shown during readline completion in the QEMU monitor is allocated dynamically but currently never deallocated. Add the missing loop which calls g_free for the allocated strings. Signed-off-by: Stefan Weil <sw@weilnetz.de> Reviewed-by: Stefan Hajnoczi <stefanha@linux.vnet.ibm.com>
* readline: Fix buffer overrun on re-add to historyMarkus Armbruster2011-11-071-1/+1
| | | | | | | | | | | | | | | | readline_hist_add() moves the history entry to the end of history. It uses memmove() to move rs->history[idx + 1..] to rs->history[idx..]. However, its size argument is off by two array elements, so it writes one element beyond rs->history[], and reads two. On my system, this clobbers rs->hist_entry and the hole right after it. Since the function assigns to rs->hist_entry in time, the bug has no ill effects for me. Spotted by Coverity.

* monitor: Improve mux'ed console experience (Jan Kiszka)aliguori2009-03-051-0/+5
| | | | | | | | | | | | | | | Up to now, you never really knew if you already switched the console after pressing CTRL-A C or if you mistyped it again. This patch clarifies the situation by providing a prompt in a new line and injecting a linebreak when switching away again. For this purpose, the two events CHR_EVENT_MUX_IN and CHR_EVENT_MUX_OUT are introduced and distributed on focus switches.

* monitor: Introduce ReadLineState (Jan Kiszka)aliguori2009-03-051-207/+189
| | | | | | | | | | | | | As another step towards decoupled monitor terminals encapsulate the state of the readline processor in a separate data structure called ReadLineState and adapt all interfaces appropriately. For now the monitor continues to instantiate just a single readline state.

* monitor: Rework API (Jan Kiszka)aliguori2009-03-051-18/+29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Refactor the monitor API and prepare it for decoupled terminals: term_print functions are renamed to monitor_* and all monitor services gain a new parameter (mon) that will once refer to the monitor instance the output is supposed to appear on. However, the argument remains unused for now. All monitor command callbacks are also extended by a mon parameter so that command handlers are able to pass an appropriate reference to monitor output services. For the case that monitor outputs so far happen without clearly identifiable context, the global variable cur_mon is introduced that shall once provide a pointer either to the current active monitor (while processing commands) or to the default one. On the mid or long term, those use case will be obsoleted so that this variable can be removed again. Due to the broad usage of the monitor interface, this patch mostly deals with converting users of the monitor API. A few of them are already extended to pass 'mon' from the command handler further down to internal functions that invoke monitor_printf. At this chance, monitor-related prototypes are moved from console.h to a new monitor.h. The same is done for the readline API.
