Description Frank Ch. Eigler 2006-03-02 15:19:28 UTC

Description of problem:
Looking at the web server logs, and at tcpdump packet dumps, it seems
that during the main RPM-by-RPM installation phase, anaconda is requesting
each RPM *twice*.  It doesn't use HEAD or get a partial copy - it GETs the
whole darned RPM each time.

Comment 1 Jeremy Katz 2006-03-02 19:11:29 UTC

It should be just doing byte-ranges to get the header for the first stage.

What web server are you using?

Comment 2 Frank Ch. Eigler 2006-03-02 19:28:17 UTC

The web server runs apache 2.0.53-3.4.legacy with a customized configuration. 
The byte range makes sense, however in the tcpdump packets, I recall no sign of
the Range:-related headers.  In case a web server doesn't support byte ranges
(for whatever reason), do you think it is reasonable for anaconda/urlgrabber to
request two copies?

Comment 3 Chris Lumens 2006-03-13 19:29:29 UTC

Can you attach some of your web server logs or tcpdump output?

Comment 4 Frank Ch. Eigler 2006-03-13 19:44:13 UTC

The web server logs simply indicate consecutive identical downloads:

dhcp7.elastic.org [192.168.1.17] - - [02/Mar/2006:11:52:36 -0500] "GET
/%7Efche/FC5/Fedora/RPMS/xorg-x11-drv-sis-0.8.1.3-1.2.i386.rpm HTTP/1.1" 200
289210 "-" "urlgrabber/2.9.6"
dhcp7.elastic.org [192.168.1.17] - - [02/Mar/2006:11:52:37 -0500] "GET
/%7Efche/FC5/Fedora/RPMS/xorg-x11-drv-sis-0.8.1.3-1.2.i386.rpm HTTP/1.1" 200
289210 "-" "urlgrabber/2.9.6"

Searching backward through the logs, I see when the range query was done during
the planning stage:

dhcp7.elastic.org [192.168.1.17] - - [02/Mar/2006:10:04:22 -0500] "GET
/%7Efche/FC5/Fedora/RPMS/xorg-x11-drv-sisusb-0.7.1.3-1.2.i386.rpm HTTP/1.1" 206
3558 "-" "urlgrabber/2.9.6"

The same pattern appears for every RPM installed, starting libgcc-4.1-0.27.

Comment 5 Chris Lumens 2006-04-12 18:15:01 UTC

Yep, we certainly were downloading each package twice.  Fixed in Rawhide. 
Thanks for the report.
