Replace=True clarification w/r to List values

[Darren Govoni]

Hi,
I'm using boto 2.04b and need some clarification of how boto treats
replace=True with respect to list values.

I am comparing two SimpleDB implementations, AWS and M/DB.

I get different results with the same boto code.

The issue is when an attribute is being set to/replaced with a list of
values.

boto+SimpleDB will overwrite the attribute old list with the new list.
boto+M/DB will replace the attribute with only the 'last' value of the
list, leaving only a single value.

The author of M/DB can't find an inconsistency with respect to SimpleDB
documented behavior.

So what is the correct behavior/expected behavior with respect to lists?
Its odd that it returns different results with the same code.

The SimpleDB implementation is the correct one. When it's updating a
list with replace=True, it should wipe out the old values and replace
them with ALL of the new values, not just the last one. Not sure what
the difference is that M/DB has but I don't know of any special
handling case that we do for SDB that would be different for M/DB.
