Bug#740874: bash: history search broken in horizontal-scroll-mode

[Jakub Wilk]

Package: bash
Version: 4.3-2
Usertags: serious




I've attached a small script that simulates the following sequence:

echo foo
<Ctrl+R>foo<End>

With bash (<< 4.3), the result of running this script was:

jwilk@borsuk:~$ bash -i < test-search-hist
stdin: is not a tty
jwilk@borsuk:~$ echo foo
foo
jwilk@borsuk:~$ echo foo
foo
jwilk@borsuk:~$ exit




jwilk@borsuk:~$ bash -i < test-search-hist
stdin: is not a tty
jwilk@borsuk:~$ echo foo
foo
jwilk@borsuk:~$
foo
jwilk@borsuk:~$ exit



- horizontal-scroll-mode is enabled in inputrc;
- TERM=linux;
- a UTF-8 locale is set (e.g. LC_ALL=C.UTF-8);
- PS1 is not very long.

History search is broken if horizontal-scroll-mode is enabled in inputrc. But with bash (>= 4.3), the second "echo foo" disappears when you press End (or any arrow key): I've been able to reproduce this bug only if all of these conditions are met:
