Machine Type: x86_64-suse-linux-gnu
Bash Version: 4.2
Patch Level: 42
Release Status: release
Description:
As subject says:
* If checkwinsize is _not_ set the bash does not update the
internal LINES and COLUMNS varaible during a command/job is
running in foreground on same terminal.
* If checkwinsize is set bash/libreadline does export LINES and
COLUMNS breaking ncurses/TIOCGWINSZ based commands/jobs.
both cause bug reports here. That is if I override the default and
set the check_window_size to 1 in jobs.c I'll beaten by bug reports
and upstream (compare e.g. with
https://bugzilla.novell.com/show_bug.cgi?id=793536).
If I do not change the upstream behaviour I'll also beaten by bug
reports because know bash does not know about size changes during
an other job is in foreground
(compare e.g. with https://bugzilla.novell.com/show_bug.cgi?id=828877)
Fix:
The bash/libreadline may (IMHO) update LINES and COLUMNS after a job
without exporting LINES and COLUMNS. Simply to have a correct command
line behaviour of the bash its self after jobs had finished as well
as for the jobs them self to not to depend on static LINES and COLUMNS
but on TIOCGWINSZ only.
