Feature changed by: Ján Kupec (jkupec) Feature #302159, revision 61 Title: zypper: Add option to only download packages (-d) openSUSE-10.3: Rejected by Stanislav Visnovsky (visnov) reject date: 2007-06-19 14:19:54 reject reason: Postponing. Priority Requester: Desirable Projectmanager: Important openSUSE-11.0: Rejected by Stanislav Visnovsky (visnov) reject date: 2008-04-04 14:32:54 reject reason: Running out of time, postponing. Priority Requester: Desirable Projectmanager: Important - openSUSE-11.1: Rejected by Stanislav Visnovsky (visnov) - reject date: 2008-07-11 22:23:41 - reject reason: Postponing. + openSUSE-11.1: Done Priority Requester: Desirable Projectmanager: Important openSUSE-11.2: Done Priority Requester: Desirable Projectmanager: Important Requested by: Jiri Srain (jsrain) Description: rug has a '-d' option which causes it only download packages, not to install them. zypper does not have one. to make use of such options (download packages and install them later) zypp must be able to keep the packages downloaded and use them later instead of downloading them again (eg. some kind of persistent cache). References: https://bugzilla.novell.com/show_bug.cgi?id=230704 See also feature #300747 and #305624 Test Case: * Run zypper with: zypper install --download-only [package] * Subsequent "zypper install [package]" (without --download-only) should not download the package again, just install it. * This should work with install, update, dist-upgrade, patch, and verify commands Discussion: #2: Ján Kupec (jkupec) (2007-06-05 13:43:33) (reply to #1) First, we must have a clue how to do it :O) #5: Michael Andres (mlandres) (2007-06-18 13:21:51) (reply to #2) We need a persistent package cache, where packages are indexed by MD5, SHA. Commit has to be rewritten to separate download and install code (still offering alternating download/install or download all then install). And we need some cache cleanup policies. But we probabely don't want to do this before we know the refactored zypp runs smoothly, so I would not promise this for 10.3 #8: Federico Lucifredi (flucifredi) (2007-06-18 15:48:59) (reply to #5) As an aside, indexing will cause you probelsm with blind-revisioned packages, depending on how you implement it. #4: Duncan Mac-Vicar (dmacvicar) (2007-06-18 09:19:27) (reply to #3) This means changing the commit, and we can only do that if we are ahead of time with the other changes. #6: Jiri Srain (jsrain) (2007-06-18 14:40:08) Duncan, Michael, thanks! Stano, please, postpone for 11.0. #7: Federico Lucifredi (flucifredi) (2007-06-18 15:46:55) Lets not forget that 70%+ of OpenSUSE users have broadband according to the survey, which means this is a marginal advantage, albeit a nice one (I imagine, users who are charged by the bit, and advanced users doing who-knows-what will take advantage of the ability to retrieve packages from the cache). #13: Jan Engelhardt (jengelh) (2009-03-01 17:02:04) (reply to #7) Broadband is actually a pretty broad term, and so the survey item probably did not have much value. #10: Stanislav Visnovsky (visnov) (2007-11-23 11:26:31) zypper improvements, commit re-factoring. #14: Elmar Stellnberger ATK (estellnb) (2009-03-26 13:04:40) One advantage will be that packages can be inspected by a prog. such as mc in advance to installation or to manually take them apart by rpm2cpio. Sometimes it is necessary to add special rpm-installation options as --excludepath or --excludedocs to install several versions of a single package for downward compatibility. Furthermore in combination with an upcoming --arch switch it may enable to download packages on a server to be installed on another system/machine. f.i. the ati repo can not be browsed via http so that it is necessary to download packages from it via zypper rather than a web browser. #17: Michael Andres (mlandres) (2009-07-21 12:30:27) libzypp-6.11.0 allows to set different download policies in ZYppCommitPolicy (DownloadOnly, DownloadInAdvance, DownloadInHeaps, DownloadAsNeeded). #19: Ralph Ulrich (ulenrich) (2009-08-12 13:02:52) (reply to #17) As in factory zypper is 1.2.2 as of now: I searched how to handle ZYppCommitPolicy - I didn't find any documentation about. Shouldn't there? #20: Ján Kupec (jkupec) (2009-08-12 13:35:58) (reply to #19) Please read more thoroughly. Comment #17 does not mention zypper, but libzypp. It was an information for developers using libzypp. As for zypper, the only thing that has been added in regard of commit policy so far, is the --download-only option, but in 1.2.3, not 1.2.2! It will be documented in zypper's man page, and its help texts (e.g. zypper help install). #23: Martin Vidner (mvidner) (2009-08-27 16:09:51) (reply to #20) I have bumped the version to zypper-1.2.3 (in home:mvidner, SRI 19048 to zypp:Head). It implements --download-only. #18: Ján Kupec (jkupec) (2009-07-27 15:22:59) Done also in zypper (--download-only/-d added to several commands). To be in zypper 1.2.3 #22: Ralph Ulrich (ulenrich) (2009-08-26 13:26:52) (reply to #18) zypper version halted at 1.2.2 ever since? I would really like this feature in openSUSE-11.2 And status is done for openSUSE-11.2 -- openSUSE Feature: https://features.opensuse.org/302159
