I asked on #xorg-devel about our issue with ^C not working in gdb. So, we seems to have encountered a long-standing problem, not related to MIPS or a specific version of GDB: <bernie> is it still to be expected that gdb can't stop the X server with ^C ? <bernie> I'm debugging on a mips platform... it may very well be a platform bug <bernie> ajax, airlied: maybe one of you knows? <airlied> bernie: I'm not sure its ever worked for me, I generally kill -INT `pidof Xorg` <whot> it works if you attach to a running server, not if you start through gdb <bernie> whot: indeed, I just discovered it <bernie> I wonder if it's a bug in gdb <bernie> airlied: thanks for the suggestion, I thought it was just me :) <airlied> I think X might change TTY state and piss gdb off <bernie> airlied: oh, good point (although I'm debugging over ssh, it would be a bug for X to attempt changing that tty rather than the actual console) <bernie> xf86DrvMsg(pScrn->scrnIndex, from, "Using %sware Cursor\n", <bernie> lol <nwnk> ^c'ing a running server is expected to work, regardless of how you attached gdb. <nwnk> if it doesn't it's a bug in gdb or in the kernel's signal delivery code <bernie> nwnk: I have "NoTrapSignals", but it doesn't help <bernie> nwnk: I suspect a bug in gdb... <nwnk> wouldn't be the first <bernie> nwnk: as a matter of fact, X is resilient to ^C even when running standalone <whot> really? that'd be news to me <jcristau> ^c in gdb doesn't send sigint to the traced process though, it sends sigint to gdb <bernie> whot: only when it's sort of crashed :-) <bernie> whot: or maybe it's because of the NoTrapSignals <nwnk> jcristau: right; gdb should then handle it according to whatever you set for 'signal SIGINT', which defaults to 'stop' <nwnk> excuse me, 'handle SIGINT' <nwnk> but what often seems to happen is the signal just gets ignored by both -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ _______________________________________________ xorg-devel mailing list [email protected] http://lists.x.org/mailman/listinfo/xorg-devel
