Fate #300660: Download package groups before install
Discussion:
#2: Klaus Kämpf (kwk) (2006-08-09 11:36:42)
Michael already looked at this. Should be further evaluated for 10.3
#3: Edith Parzefall (emapedl) (2007-07-31 16:56:12)
Problem is: what do we do if we lost the network connection when only
half the packages are installed?
#7: Reinhard Max (rmax) (2008-04-10 11:42:43) (reply to #3)
I think this is a general problem for network based installations. Can
you elaborate if/why you see this as a special problem when download
and installation are running in parallel?
#8: Peter Poeml (poeml) (2008-05-19 14:49:53) (reply to #7)
For reliable operation of a business critical server, it is a must that
packages are downloaded first, before the installation/update is
started. Otherwise a network outage can lead to a broken system which
is half updated.
So if parallel download/install is implemented (for desktop users,
maybe...) then please make sure that it is possible to disable it.
#9: Reinhard Max (rmax) (2008-05-19 16:01:15) (reply to #8)
As we just sorted out on IRC, the current implementation also doesn't
allow to complete download before starting installation and the feature
proposed here wouldn't make this worse.
But as the wish of server admins to have all packages downloaded before
starting to install them is very valid, I think we should extend this
feature request to contain that requirement as well, and probably
rename it to "decouple download and installation".
If download and installation are properly decoupled, it should just be
a matter of the parameters the algorithm is called with to get one of
the following behaviours:
* Download and install packages one by one (as it is now)
* Keep downloading subsequent packages while installing (as originally
proposed here)
* Use a fixed-size download cache for flow control between download an
installations (in situations where download is faster than installation
and disk space is limited)
* Download all packages of an update or installation and install them
afterwards (as requested by Peter for server admins)

We already do have similar feature: #300660: Download package groups
before install
#4: Edith Parzefall (emapedl) (2007-07-31 16:57:22)
Please reject for 10.3.
#5: Duncan Mac-Vicar (dmacvicar) (2008-01-10 16:23:46)
This is included in the ZYpp plan for 11.0, however implementation will
start after beta. Will keep in evaluation, it depends on other
milestones for beta1
