MAXLEN definitely needed to be bigger to properly format fairly common connection strings. In addition, the reliance on xsnprintf helps detect cases where even this buffer is not long enough. the buffer in parse_config has been made bigger in a bit of sloppy programming, but what really needs to happen is reporting when a line cannot be properly parsed/is too big for the buffer. That is just a kludge. Signed-off-by: Dan Farina <drfarina@acm.org> Signed-off-by: Peter van Hardenberg <pvh@heroku.com>
