Crash or return forbidden value?
CChris posed the question. I always have a tough time with this one. I can give
a few examples:
1. Open a file that does not exist. Well, the user may wish to try a different
file. Error code.
2. Connect to a database server fails. Error code, as you may have given
incorrect login credentials by user input and want to prompt the user for the
username/password again.
3. Requesting an out of bounds index for a given sequence. Crash. This tends to
be a programmers fault, not a users fault. The methods find_from, rfind_from,
etc... do this.
Now, translate that into a set of rules? Hm. Any thoughts? There seems to be
some theme going on of "testing the waters" vs. "do this just as I say", but I'm
not sure.
This is a good topic, thanks Chris for posing the question.
