Feature changed by: Ján Kupec (jkupec) Feature #305553, revision 36 Title: zypper: dist upgrade could error out if more than one repository with a base product exists openSUSE-11.2: Candidate Priority Requester: Important Projectmanager: Important Requested by: Dirk Mueller (dirkmueller) Description: I've just learned over lunch that calling "zypper dup" is wrong if you have both buildservice repositories and a distribution repository enabled. apparently one has to call it with -r name, where name points to the distribution one wants to upgrade to, and the other repositories (e.g. buildservice addons) must not be dup'ed, but only updated via update -t package. I've verified that this indeed fixes the "reinstalling/downgrading package" issues everyone seems to be complaining about. It would be nice if zypp/zypper could detect this situation and advise the user, or alternatively do the right thing automatically. I'm not sure if channels of distributions (e.g. the factory channel, or a future openSUSE 11.0 channel) can be detected in some way.. if it does, then it could automatically add the -r argument if there is only one distribution channel enabled, and altneratively error out if more than one distribution channel is in the sources list and no -r argument was given. Relations: - make zypper dup error out if more than one repository exists (novell/bugzilla/id: 385972) https://bugzilla.novell.com/show_bug.cgi?id=385972 Discussion: #1: Stephan Kulow (coolo) (2008-05-11 02:20:39) * ** Bug 388956 has been marked as a duplicate of this bug. *** #2: Duncan Mac-Vicar (dmacvicar) (2008-12-10 15:31:24) Hm. If that is so, this feature is really important :O) Just a side question: how does installation handle this (if at all)? Currently they can't, we need to add means of such identification (as well as identification of update repos). yup, sounds good #3: Lukas Ocilka (locilka) (2008-05-12 06:17:43) Installation/Upgrade has the installation repository registered as the fist one, then Add-Ons or other repositories can be added or enabled. Upgrade doesn't handle how the packages are selected to be upgraded, it just calls solver. OK, some packages are dropped by installation by default :) See bug #300540. #4: Stephan Kulow (coolo) (2008-05-12 06:25:06) the main difference: it's pretty unusual to have 13 repos during distribution update with very comparable versions. While it's not to for zypper dup. BTW: another difference: installations sets YAST_IS_RUNNING=instsys, which some packages cause not to produce errors on updates. This might be good for dup, but bad for update #5: Duncan Mac-Vicar (dmacvicar) (2008-12-10 16:56:35) Note, I moved the bugzilla entry to fate, but mls claims the bug is invalid, as it is a perfect use case to do dist upgrade with various repositories. So this feature has to be evaluated with care and gathering opinions from various sources. It may be invalid. #7: Jiri Srain (jsrain) (2008-12-11 07:58:04) (reply to #5) I don't think it is invalid; I happened to downgrade several packages from OSS repo via zypper dup :-( #8: Duncan Mac-Vicar (dmacvicar) (2008-12-11 10:10:32) (reply to #7) The solution of stop-with-error if there is more than one repository is invalid because prevent the valid usecase of dist-upgrading with more than one repo enabled (as mls pointed out). What is valid about the feature, is that multiple repo upgrade can be dangerous, and we may warn the user if there are repos for different products there. #9: Jiri Srain (jsrain) (2008-12-11 10:53:42) (reply to #8) Sorry for not being precise in my comment: of course user must be able to override this error/warning/whatever. #6: Duncan Mac-Vicar (dmacvicar) (2008-12-10 18:34:19) Idea from mls: Use the CPE ids introduced in 11.1 to issue a warning if repositories are mixed. #10: Ján Kupec (jkupec) (2009-06-24 09:33:26) Michael, is this still relevant? Is this related to the planned --from option? #11: Michael Schröder (mlschroe) (2009-06-24 11:33:46) (reply to #10) This has nothing to do with --from, it's about doint 'zypper dup' to update the system to the next release while still having old repositories enabled. #12: Ján Kupec (jkupec) (2009-07-07 16:26:43) (reply to #11) So multiple repositories are not a problem in general, but multiple repos for different products are! OK, so now back to the solution: can you tell me or point me to some info abou these CPEs Duncan mentions in c#6? I guess they are part of the product solvable and are available as solv attribute? If so, all that's needed is to check whether there are multiple repos with a different product and write a warning if that's the case, right? #13: Michael Schröder (mlschroe) (2009-07-07 16:34:14) (reply to #12) ma, is there a libzypp interface? #14: Michael Andres (mlandres) (2009-07-13 14:16:11) (reply to #13) Yes. Since you can ask for a products CPEid, or for the CPEids related to a repository (supported or updated products). But I don't know if those CPEids are meanwhile included in the metadata (see bnc #459527). #15: Ján Kupec (jkupec) (2009-07-14 18:17:17) (reply to #14) OK, so this should not be too much work. So to sum it up: * zypper: show a warning in 'dup' if there are multiple base repos with different CPEids enabled. * metadata: check/include the CPEid in product metadata (who should do this?) #16: Ján Kupec (jkupec) (2009-07-27 17:30:09) (reply to #14) Rudi, please look at c#14 and 15 #17: Ján Kupec (jkupec) (2009-07-29 19:04:40) Current status: * TODO: put CPE IDs to content/prodcuts.xml metadata (still nobody assigned to do this!) * TODO: satsolver will need to parse the above (or is this ready already?) * PROBLEM: we need to figure out which repos don't go together for dup. I proposed to compare CPEs of 'base' or 'platform' repos, but we have no 'isBase' flag in product or repo metadata. Simply checking for different CPEs is not enough (think of one base product and one addon - two different CPEs, but 'dup' is OK with them). * PROBLEM: even if we'll have the 'isBase' flag, we'll be stuck in case of two different, but compatible bases, like e.g. SLES and SLED could be used standalone or with SLED as an add-on to SLES in the past. Do we still allow this? Any ideas? #18: Ruediger Oertel (oertel) (2009-07-30 17:20:05) adding more data (like the CPE-ids) is not a big issue. the problem for me is rather how to obtain a CPE-id #19: Marcus Meissner (msmeissn) (2009-08-04 17:55:08) CPE ids can be defined by the vendor as I udnerstand ;) I mailed Jan and Rudi. my suggestions would be: cpe:/o:opensuse:opensuse:11.1 cpe:/o:novell:suse_linux_enterprise:11:ga:server cpe:/o:novell: suse_linux_enterprise:10:sp2:desktop #20: Ralph Ulrich (ulenrich) (2009-08-05 13:25:05) (beginners question) Why products at all. Debian/Ubuntu do have so called meta-packages , which are normal package that pull in stuff: minimal, standard ...etc Without products you would loose an additional level of complication? #21: Ján Kupec (jkupec) (2009-08-05 15:02:36) (reply to #20) Using metapackages for puling stuff does not exlude using of CPE ID. It's just means to uniquely identify a product and can be used by Debian's metapackages as well. Other than that, your question is not related to this FATE, and is more appropriate for opensuse-softwaremgmt@opensuse.org mailing list. But you might find the answer also here http://en.opensuse.org/Product_Management #22: Ján Kupec (jkupec) (2009-08-19 17:25:34) We still need to do the TODOs and resolve the issues from c#17 here. If you have an idea, please speak up. #23: Klaus Kämpf (kwk) (2009-08-25 09:36:05) I believe the request title is wrong and should be adapted. Indeed 'distribution upgrade' is special, as it considers one repo to be 'authorative' and thus dictating package versions, which might result in a version downgrade. 'zypper dup' should provide support for this and, in case of multiple 'product' (resp. base) repositories request a decision from the user. There are two things to be solved from my pov * Detection of a 'base' vs. 'addon' repo. Could be done by looking at a 'product' resolvable. * Specifying the 'authorative' repo in case of dist upgrade. ie. passing a '--product foo' or '-to repo' to zypper. #24: Ján Kupec (jkupec) (2009-11-18 15:59:55) (reply to #23) Detection of base vs. addon is what we currently lack. The authoritative repo can now be selected using --from option. 'zypper dup --from repo-oss'. + #26: Ján Kupec (jkupec) (2009-11-20 15:29:56) + Following Jiri's suggestion, i've done this the simple way for now: if + --repo or --from are not used, and multiple repos are enabled, 'zypper + dup' will show a warning and a hint that the user should check the repo + list for incompatible repos. -- openSUSE Feature: https://features.opensuse.org/305553
