Description David Balažic 2003-01-20 17:29:09 UTC
Description of problem:

If I press ctrl-Z when man is displaying a manual page, then man can not be 
restored any more.

Version-Release number of selected component (if applicable):

man-1.5j-12.i386.rpm

How reproducible:


Steps to Reproduce:
1. login on VT1
2. "man sfdisk"
3. ctrl-Z
4. "fg"
    
Actual results:

man exits

Expected results:

man resumes and can be used to view the page

Additional info:

ctrl-Z works fine with other programs, like sleep , less or vi

Comment 1 David Balažic 2003-01-30 18:16:32 UTC
Same thing in phoebe2 ( 8.0.93 ).
man-1.5k-2

All default settings; shell is bash etc.

Comment 2 Bill Nottingham 2003-02-11 05:40:06 UTC
Works for me with current packages - does it work for you?

Comment 3 David Balažic 2003-02-13 09:29:42 UTC
Yes, but there is still something weird :

man ls
press ctrl-Z after the page appear :
no shell prompt.
press RETURN -> shell prompt appears.

This happens if ctrl-z is pressed in less than 9 seconds
after man ls is started. If pressed after 9 or more seconds,
then it behaves OK.


Comment 4 David Balažic 2003-02-14 08:40:00 UTC
More info :
kernel-2.4.20-2.21 -> man on ctrl-z exits ( terminates )
kernel-2.4.20-2.41 -> man on ctrl-z stops, with the 9 second issue descibed in 
comment #3



Comment 5 Eido Inoue 2003-08-07 21:47:33 UTC
I'm going to leave this as a feature for upstream. Most apps that do non-trivial
screen manipulation with a library have to be specifically written to support
application suspension. (that is, put the terminal in a sane state) Hence the
need for a "terminal reset" feature in most X-based terminal programs...

> most X-based terminal programs

? I was doing everything on text console, without X

Comment 8 Eido Inoue 2003-08-08 15:27:25 UTC
The analogy for a terminal reset in the console would be something like "stty sane"
