Description Hunter Matthews 2001-12-21 19:21:51 UTC
Description of Problem:

RHN at least with client 2.7.4 does not compress the rpm 
headers 
before downloading them, as it does with the listPackages info.

Without 
modifing the client, the server could compress the headers and
have the normal cgiwrap 
decompression work by setting the Content-Type
to "application/compressed-octet-
stream"

This is probably only important for modem connected users, as most headers are 
not that large.

Comment 1 Mihai Ibanescu 2001-12-21 19:41:40 UTC
This is a known issue. The compression can't be initiated from the server side
since it would break old clients. The client has to explicitly say it wishes the
headers to be compressed, but this would trigger another bug in python's socket
module.

We should be able to turn compression on for the new clients, though.

misa, please take care of this issue

Comment 3 Mihai Ibanescu 2002-07-18 20:07:04 UTC
The header is already a compact binary representation, I will have to run some
benchmarks to see how well a header compresses. listPacakages is a different
beast, its output is XML, and XML compresses well (IIRC, from 100k to 16k).

Header is already a compact binary representation...

Shall we close this???

Comment 5 Hunter Matthews 2002-09-17 19:57:08 UTC
Sure (it was a suggestion, not a bug report) In playing around here, there's
_is_ an advantage to compressing the headers, but it would only be noticable on
modem lines.
