New submission from ptz <ppt...@gmail.com>:
In Python 2.4, Assuming we've imported telnetlib, the following works:
>>> f = telnetlib.Telnet("some_text_based_server")
>>> f.read_very_eager()
The last call outputs the text that the server outputs upon connection (e.g.
"login: ").
However, if we put this inside a function it does not work:
>>> def g():
... f = telnetlib.Telnet("server")
... data = f.read_very_eager()
... print data
...
>>> g()
This returns the empty string. I believe this indicates that the data from the
server isn't cooked.
Note that if we use read_until() instead of read_very_eager(), everything works
as expected, further supporting the hypothesis that data doesn't cook properly
when the functions are called as above.
So why the difference?
