While imports readline in python, if TERM in terminfo is available and it contains the variable 'km' and 'smm', the readline initialization will output the value of 'smm' which is the escape sequence '\E[?1034h'.
'km' means the terminal has a meta key which is a special key on MIT keyboards, 'smm' means turn on the meta key if this terminal has one. There are 4 solutions to fix this issue: 1) Preserving TERM and unsetting TERM, or setting TERM with a terminal without 'smm' (such as terminal 'dumb'). This is the most common approach. But the effect is global even we don't import readline. https://bugzilla.redhat.com/show_bug.cgi?id=304181 http://bugs.python.org/issue11390 http://lists.gnu.org/archive/html/bug-readline/2013-06/msg00000.html 2) Modify readline.c in python, mandatory let readline use a term without 'smm' as terminal (such as 'dumb'), it is similar to the above solution, but it localizes the effect in readline. The reason why choose 'dumb' is GNU Readline library use 'dumb' as default term when TERM is unset. 3) Modify terminfo.src in ncurses, let terminfo database doesn't contian 'smm', but the number of terms we supported is limited. 4) Modify terminal.c and readline.c in GNU Readline library to explicitly disable meta key, or just comment out the outputting code. This patch implements solution 2, I think it has the least side effect.
