Priority Requester: Important Projectmanager: Important openSUSE-11.3: Evaluation Priority Requester: Important Projectmanager: Important Requested by: Klaus Kämpf (kwk) Requested by: Peter Poeml (poeml) Requested by: Reinhard Max (rmax) Description: Network installation could be improved by running package download and package installation in parallel.

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) #10: Jiri Srain (jsrain) (2008-05-20 10:22:10) (reply to #9) 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 #14: Chris Hills (chaz6) (2009-02-16 16:42:06) Is there a feature request to install using both the base and updates repo so that the latest packages available at install-time are used, thus saving bandwidth? #15: Jiri Srain (jsrain) (2009-02-17 08:45:38) (reply to #14) This is how it works for quite some time. Repositories providing patches also provide the packages so that they can be installed directly from the update repositories (provided they contain newer version). #16: Duncan Mac-Vicar (dmacvicar) (2009-06-02 15:18:00) For 11.2 we will focus on flexibility of the download and install order (like installing after everything is downloaded), however parallel stuff should be done after we have this in place. Please reject. #17: Michal Papis (mpapis) (2009-07-04 20:58:23) I think great example here may be Gentoo, there You can chose the way of getting packages, by default download and installation go in paraler, but it is possible to get first sources and then run build/installation. If you are on the default and something breaks, ex. network, Yuo can always resume the last download&installation task. #18: Giuseppe Salinaro (superpeppo89) (2009-07-16 19:37:27) (reply to #17) This idea of gentoo is good... + #19: Ján Kupec (jkupec) (2009-07-20 10:59:31) (reply to #18) + Guys, as Duncan wrote in c#16, we are already developing the "download + all, install all" mode (currently we only have "download one, install + one, ..."), and yes, users will be able to choose one of these. This + particular feature would be an improvement of the current mode: + "download one, install one while downloading others, ...". I hope this + clarifies the current status a bit. -- openSUSE Feature: https://features.opensuse.org/120340
