question about solveDependencies

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA1

I was attempting to install an entire update using current
the other day
and I ran into problems with solving deps.  I tracked it
down to the end
of db.currentdb.solveDependencies where the result is read
from the db
query and then reversed and made into a dict of lists (I
think).
Anyway, it seems from what I'm seeing (and also from the
comment just
above that) that this code is for pysqlite.  Anyway, in the
end the
function is returning a null set and I'm wondering why. 
More
importantly, what is it supposed to be returning??

Thanks,
Jared

Jared,

There is some code in there to work with PySQLite's iterable
objects
that it returns.  It doesn't return a normal list but a
class that
acts like a list or that can be accessed like a dictionary.
Many parts
of the code were sensitive to the difference so the results
from
fetchall() are dumped into a real list there.  The DB API
2.0 dictates
that fetchall returns a list like object so this code should
not
impact other compliant DB APIs.

Otherwise, solveDependancy() returns a list of tuples
containing n, v,
r, e, a, and size.  Where the package idicated by the tuple
will
provide the needed requirement that was passed in to
solveDependancy().

Can you give me an example of what this list of tuples would
look
like?  I just want to make sure I'm passing things around
correctly.
