Re: io:lines() and \0

[djczaski@...]

I was curious how Python would handle this evil and non portable mess:

    $ cat io.py

    from string import printable

    f = open('foo', 'w')

    for i in range(0, 5):

        f.write("hello\0world\n")

    f = open('foo', 'r')

    for l in f.readlines():

        print ''.join(c if c in printable else '.' for c in l),

    $ python io.py

    hello.world

    hello.world

    hello.world

    hello.world

    hello.world

Hi all,

I just noticed that io:lines() does not cope with \0 in the lines, and thus just returns truncated lines (lua-5.2.3, but legacy 5.1 likewise).

May I suggest replacing the call to fgets in src/liolib.c so that we can read lines with \0 data?
