Merge lp:~ara/ubuntu-qa-tools/fix_dl_ubuntu_test_iso into lp:ubuntu-qa-tools

[Ara Pulido]

Steve,

Some of your changes didn't work for me. I have made some changes to it. Can you review them ASAP, please?

 * BASEURL was not working, as it includes rsync://, but, as it is not used anymore, it is ignored now.
 * USERNAME/PASSWORD were interfering with USERNAME shell variable, and, therefore, always failing. Changed those to DLUSERNAME/DLPASSWORD
 * The man page needed an update

Thanks, Ara, merged. I did modify it slightly to warn when BASEURL is specified, so that people setting it would know that it's not going to be honored.

+.TP
+.B \-\-variant variant 
+Only download a specific variant of Ubuntu (e.g. dekstop,
+alternate, server, dvd). The \-\-variant option can be given
+multiple times to specify than one variant.
+.TP
+.B \-\-arch arch
+Only download a specific architecture of Ubuntu (e.g. i386,
+amd64). The \-\-arch option can be given multiple times to request
+more than one arch.
+.TP
+.B \-\-bwlimit=KBPS
+This option allows you to specify a maximum transfer rate in
+kilobytes per second; equivalent to adding the same argument to
+the OPTS variable to be passed on to rsync(1). Note that zsync
+does not support bandwidth limiting.
+.TP
+.B \-\-no-verify
+This option tells the script to skip the hash comparison check
+against the MD5SUMS file that is normally done by default.
+.TP
+.B \-\-no-zsync
+By default, the script will attempt to use zsync if it is
+available as it uses fewer resources on the cdimage server.
+However, because it does not do rate-limiting and has other
+limitations, using only rsync may be preferred.
+.TP
+.B \-\-isoroot directory
+The local path underneath which the downloaded isos should be
+stored. The default is ${HOME}/iso.
+.TP
+.B \-\-config config
+Specify an alternate location for the config file; the default
+is ${HOME}/.dl-ubuntu-test-iso.
+.TP
+.B \-\-host hostname
+The mirror to pull the cdimages from. The default is
+cdimages.ubuntu.com.
+.TP
+.B \-\-user username
+If http_auth is used on the cdimage server, specify the username
+with the \-\-user argument. You can also set USERNAME in the
+config file.
+.TP
+.B \-\-pass password
+If http_auth is used on the cdimage server, specify the password
+with the \-\-pass argument. You can also set PASSWORD in the
+config file; note however that zsync does not support reading
+from a configuration file and thus any specified password will
+appear on zsync's command line and be visible in process
+listings.
+.TP
+.B \-\-mirror
+If set, the script will attempt to mimic the layout of the
+cdimage server. This is useful for republishing the isos in an
+alternate mirror.
+.TP
+.B \-\-no-release-check
+By default, the script will query launchpad.net to see if the
+development version of ubuntu has changed (e.g. lucid ->
+maverick) and attempt to take the change into account. Adding
+this argument disables the check.
+.TP
+.B \-\-build builddate
+Tell the script to downoad a specific build date rather than the
+current iso; default is "current"
+.TP
+.B \-\-versions
+Report the version information contained within all of the isos
+in the ${HOME}/iso/ subdirectories, including the build number.
