Description Nils Philippsen 2006-08-16 06:42:32 UTC

Description of problem:

When updating/upgrading, yum downloads headers that are nearly as large as the
final RPM itself.

Version-Release number of selected component (if applicable):

yum-2.6.1-0.fc5

How reproducible:

Easy

Steps to Reproduce:
1. yum upgrade
  
Actual results:

root@wombat:/var/cache/yum/updates/packages> ls -l
squirrelmail-1.4.8-1.fc5.noarch.rpm  ../headers/squirrelmail-1.4.8-1.fc5.noarch.hdr
-rw-r--r-- 1 root root 4502093 Aug 15 18:39
../headers/squirrelmail-1.4.8-1.fc5.noarch.hdr
-rw-r--r-- 1 root root 4502533 Aug 15 18:39 squirrelmail-1.4.8-1.fc5.noarch.rpm

Expected results:

yum headers significantly smaller than RPM (I don't think squirrelmail has only
440 bytes of payload).

Additional info:

I've seen this for quite a while, interesting is that there are no headers in
the repositories I looked at, so I guess it makes partial downloads of the
packages (and miscalculates severely).

Comment 1 Seth Vidal 2006-08-19 19:21:36 UTC

this feels much more like a proxy problem to me. Something not allowing
byte-ranges and doing something broken with it.

Is there anything like that in place?

Comment 2 Nils Philippsen 2006-08-22 14:39:48 UTC

Seems to be so (but the machines I see this on use proxies I can't fiddle
with)... Would it be possible for yum to use these files as packages if it
already had to download them completely?

Comment 3 Nils Philippsen 2006-08-29 08:43:27 UTC

I saw something else, namely that some headers are in the few KB range and
others in the MB range. I guess that some mirrors don't allow partial downloads.
Reusing the (already downloaded) package file would be a big imporvement in that
situation.

Comment 4 Jeremy Katz 2007-04-25 18:17:59 UTC

With yum 3.1.x and beyond, we're just killing off the header downloads entirely.
