[chef] Re: Re: Verifying remote_file checksum

[Lamont Granquist < >]

So CHEF-4502 just got merged to master last week and will be released 
with 11.10.0 and was in the 11.10.0.rc.0 released yesterday (I just 
updated the ticket correctly which was mistakenly listing it as 11.12.0).

That should mitigate at least a lot of the truncated downloads problem 
(I *think* that it may mitigate all truncated downloads in the 
remote_file resource
since we should be doing HTTP/1.1 and not using chunked encoding or 
anything like that which would not have a Content-Length header, but i'll
admit that's getting into the weeds of HTTP further than my knowledge 
goes).  There's also still the possibility of corrupted bit flipping in 
the stream which a checksum would address (or the file being transferred 
into RAM correctly but then having RAM->disk corruption or whatever due 
to crappy RAM/MB/chipset/etc), but fixing CHEF-4502 should knock down 
the probability of a corrupted download by an order of magnitude or so.
