Hi, I forwarded this bug report to upstream bug tracker. Upstream reacted very quickly noticing that this is caused by a bug in BSD libedit and committed a workaround, http://gnuplot.cvs.sourceforge.net/viewvc/gnuplot/gnuplot/src/plot.c?r1=1.138r2=1.139 As a side note, upstream suggests us to give a try to improved gnuplot internal readline (also suggests using GNU readline, not possible for us).

Hi Anton, Thanks for the quick response :) On Thu, Apr 19, 2012 at 09:57:09PM +0200, Anton Gladky wrote: Hi Ron, what is the reason of marking this bug as serious? You can take your pick of the RC severities, but I don't think we should release with a bug that makes gnuplot useless from other scripts/applications that might call it. Especially not if it's a regression of a bug that was already supposedly fixed upstream. Do you happen to have a reference to the fix or the bug report there? I couldn't find it in the Changelog, or in their tracker so far. I actually stumbled on this while trying to debug another issue, namely that gnuplot silently does nothing if called from another application. eg. if you do: system(gnuplot foo.script); then gnuplot runs, and does exit, but doesn't actually appear to execute the script ... I'm not sure yet if these two things are related (still digging into that), but I can definitely reproduce the original symptom of this bug, and there's something wacky going on when it's not run from the foreground of a shell.

I couldn't find it in the Changelog, or in their tracker so far. Ok, so before anybody else also goes on a wild goose chase over this latter part: I actually stumbled on this while trying to debug another issue, namely that gnuplot silently does nothing if called from another application. eg. if you do: system(gnuplot foo.script); then gnuplot runs, and does exit, but doesn't actually appear to execute the script ... I'm not sure yet if these two things are related (still digging into that) ... This bit isn't a bug in gnuplot, it was me being silly and just not flushing the script properly before calling gnuplot on it (and then being confused by the odd behaviour that ensued, and the original bug of this report). So ignore this part. But I can definitely reproduce the original bug. I presume it shouldn't be too hard to fix (again), gnuplot really has no reason to be reading from stdin when it's writing to a non-interactive 'terminal' such as one of the image formats. It just needs someone who knows the code well enough to know which of the bazillion places that it tries to do that need to be disabled in non-interactive modes. If there was a ready-made -dbg package I'd have possibly narrowed that down and sent a patch, but since it's easy to reproduce, I'll leave that to someone who has a debug build already available :) Cheers, Ron -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of unsubscribe.
