Description

When fetching an rpm from the content app and specifying the RANGE header, like so:

curl -k  http://foreman-nuc2.usersys.redhat.com/pulp/content/Demo/Library/custom/CentOS7/main/Packages/s/sg3_utils-1.37-19.el7.x86_64.rpm  -H "Range: bytes=1384-44339"   > foo.rpm 

if the package is being lazily downloaded, the entire file is returned and not JUST the range:

$ ls -l foo.rpm -h
-rw-rw-r--. 1 jlsherri jlsherri 646K Jun  4 09:03 foo.rpm

Once the package is downloaded, it behaves as you'd expect:

$ curl -k  http://foreman-nuc2.usersys.redhat.com/pulp/content/Demo/Library/custom/CentOS7/main/Packages/s/sg3_utils-1.37-19.el7.x86_64.rpm  -H "Range: bytes=1384-44339"   > foo2.rpm 


$ ls -l foo2.rpm 
-rw-rw-r--. 1 jlsherri jlsherri 42956 Jun  4 09:04 foo2.rpm

For el7 (at least, probably more), this causes yum/anaconda to hang up the connection as soon as it gets the amount of requested data, which makes the content app really unhappy and leads to this error:

and since anaconda receives the entire rpm instead of just the range it requested (the rpm header), it re-tries the request, and pulp continually just tries to return the entire file
