Aleksey Yeschenko reopened CASSANDRA-4669:
------------------------------------------
This patch breaks cqlsh history loading. Also, the original issue isn't an
issue at all - readline handles empty history files perfectly well.
Reverting the commit should fix the new issue.
> Empty .cqlsh_history file causes cqlsh to crash on startup.

> Not sure how I got it, but I ended up with an empty .cqlsh_history file. In
> that state, when starting cqlsh, you end up with:
> bone@zen:~/dev/boneill42/cassandra-> bin/cqlsh
> Traceback (most recent call last):
> File "bin/cqlsh", line 2588, in <module>
> main(*read_options(sys.argv[1:], os.environ))
> File "bin/cqlsh", line 2543, in main
> readline.read_history_file(HISTORY)
> IOError: [Errno 22] Invalid argument
> Its a simple fix to check for a non-empty history file. I'll attach the
> patch.
