Xavier de Gaye added the comment: There is a backward compatibility issue with changeset d5ef330bac50 that enables tab-completion in the interactive interpreter by default.
When a user is not aware of this new feature and has been implementing up to now her/his PYTHONSTARTUP file with the first example given in python 3.3 documentation at http://docs.python.org/3/library/readline.html?highlight=readline#example then each new interactive python 3.4 session reads (appending them) both history files which are saved on exit. Thus those files double their size after each interactive python 3.4 session and pretty soon become few mega bytes long with a python start up time that becomes quite noticeable. ---------- nosy: +xdegaye _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue5845> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
