Bug 17878 – nano consumes 100% CPU when it has lost its terminal

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sankara Krishnamoorthy 2003-03-20 10:13:20 UTC]

if you run nano su'ed to root inside a gnome-terminal and close the terminal
without exiting nano, nano is not terminated and consumes 100% CPU. 

On the other hand if you are a normal user, and open nano and close the
terminal, nano exits properly.


Reproducible: Always
Steps to Reproduce:
1.open gnome-terminal in GNOME2
2.su to root
3.open nano some file or any file existing or new
4. close gnome-terminal without exiting nano.

Actual Results:  
nano consumes 100% CPU

Expected Results:  
nano must be terminated and gnome-terminal must be exited

GNU nano version 1.0.9
gnome-terminal version 2.2.1

[Comment 2 Seth Chandler 2003-03-20 21:31:16 UTC]

this is a nano problem....it happens a lot of times....why i switched to vim ;-) 
 
 
if this is reproduceable, then we know what the problem is, but it happens in eterms 
and aterms....

what do you suppose the problem is?

[Comment 4 Spider (RETIRED) 2003-03-21 05:09:15 UTC]

coul'd not reproduce this in  x86 (nano 1.2.0 , gnome-terminal 2.2.1) 

[Comment 5 Mike Gardiner (RETIRED) 2003-06-09 21:06:19 UTC]

cant reproduce on x86 with nano-1.0.9-r1, or nano-1.2.1 and gnome-terminal-2.2.2, using gnome-system-monitor and top to check cpu usage. 

[Comment 6 Bas van Dijk 2003-06-23 15:55:05 UTC]

I have the same problem. But I have it both in Konsole and in the regular Linux Console. When I 
cleanly exit nano (with Ctrl-X) nano sometimes keeps running and consumes 100% CPU. 

[Comment 7 SpanKY 2003-08-18 17:17:21 UTC]

does this still occur with the 1.2.x series ?

i had this happen a lot with me, but as the version increased, the # of times this happened dramatically decreased ...

[Comment 8 SpanKY 2003-09-23 19:41:37 UTC]

looks like the bug has been tracked down ... when it's been fixed upstream i'll
fix it in Gentoo ;)

[Comment 9 SpanKY 2003-10-02 00:00:58 UTC]

added a patch to fix this to 1.2.1 and 1.2.2

[Comment 10 Prakash Punnoor 2004-02-19 13:26:18 UTC]

I use nano 1.3.1 and it doesn't appear to be fixed, ie if I open shell, su, nano and just close the shell, nano goes to 100% CPU time.

[Comment 11 SpanKY 2004-02-19 15:29:05 UTC]

send a message to the nano-devel because all my test cases have been fixed
