I have to agree with you. The checksum (or MD5 hash) method was going
to be my
suggested solution. Additionally, it seems like running a 'diff' off of
a local cached copy
is possibly frought with issues of it's own. What if the file has
changed dramatically on
the server through another commit? My diff isn't going to show that?
Anyway, regardless of the diff issue, it seems like update could
certainly send an MD5 hash
along with the version. In fact, I'll be glad to implement it, if it
would be welcome.
