[zypp-devel] New solver call : resolveQueue
by Stefan Schubert 11 Mar '09

11 Mar '09

Hi, apart from the solver call "resolvePool" ( collect all transactions from the pool, solving this transactions and writing the result back to pool) the solver can work off a given request queue too: /** * Resolve package dependencies: * * The solver works off the given queue and writes back the solution * to pool. * * Returns "true" on success (i.e., if there were no problems that * need user interaction) and "false" if there were problems. In * the latter case, use problems() and later applySolutions() * below. **/ bool resolveQueue (solver::detail::SolverQueueItemList & queue); The queue can have elements which are described in the following classes: base class: SolverQueueItem.h SolverQueueItemDelete.h SolverQueueItemInstall.h SolverQueueItemLock.h SolverQueueItemInstallOneOf.h SolverQueueItemUpdate.h Known problems: - The update and InstallOneOf request does not work correctly. - The error messages are too abstract now for the user. (Jano, you can start implementation now :-) ) Greetings Stefan -- ******************************************************************************* Stefan Schubert SUSE LINUX GmbH - Maxfeldstrasse 5 - D-90409 Nuernberg, Germany e-mail: schubi(a)suse.de ------------------------------------------------------------------------------- SUSE LINUX Products GmbH, GF: Markus Rex, HRB 16746 (AG Nürnberg) -- To unsubscribe, e-mail: zypp-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: zypp-devel+help(a)opensuse.org

[zypp-devel] Branches for openSUSE-11.0 and SLE-10-SP3: coming soon
by Martin Vidner 28 May '08

28 May '08

Hi, I plan to create branches in the yast and zypp repositores as soon as RC1 is announced. That will mean trunk will be open for 11.1 development. But do not forget to apply 11.0 fixes both to trunk and the branch until 11.0 is released. Here is the proposed text for the branch docs: http://en.opensuse.org/Libzypp/Development_Branches ZYPP Development Branches openSUSE 11.1 (development) URL: http://svn.opensuse.org/svn/zypp/trunk/libzypp/ Version: 5.*.* Note: Submit to stable. SUSE Linux Enterprise 10 SP3 (development) URL: http://svn.opensuse.org/svn/zypp/branches/SuSE-SLE-10-SP3-Branch/libzypp Version: 2.*.* FIXME Maintenance Branches openSUSE 11.0 URL: http://svn.opensuse.org/svn/zypp/branches/SuSE-Linux-11_0-Branch/libzypp/ Version: 4.*.* Note: Only shipstoppers now, maintenance updates then. They must be approved by FIXME SLE 10 SP2 (maintenance) URL: http://svn.opensuse.org/svn/zypp/branches/SuSE-SLE-10-SP2-Branch/libzypp Version: FIXME Important: If applicable, submit fixes to trunk as well. Note: We use this branch for SLE 10 SP2 maintenance. -- Martin Vidner, YaST developer http://en.opensuse.org/User:Mvidner Kuracke oddeleni v restauraci je jako fekalni oddeleni v bazenu -- To unsubscribe, e-mail: zypp-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: zypp-devel+help(a)opensuse.org

[zypp-devel] [SoC-student] Comments and new ideas about implementation of failover concept
by Gerard Farràs i Ballabriga 27 May '08

27 May '08

Hello, good afternoon :-) There are some new ideas and changes about implementation details of the concept of failover [1]. Before, our idea was to modify MediaCurl class [2] to parse a list of mirrors like this [3]. But now, new idea is to use only metalink files ([4] [5]) and don't use anymore this type of mirror lists. Libzypp could download files using an external program (ej. aria2c [6]) to avoid having to implement all the logic from zero. Why this change? - Because we think than we are reinventing the wheel in things like: * Parse HTTP codes and act according to these. * To choose the fastest mirror. How to implement? I think we can do the implementation with some changes: - Modify media/MediaAccess.cc [7] and check if there are available tools like aria2c in the target system. - If we get a negative response we must use MediaCurl (like now). - If we get a positive response we can use a "new" class called MediaArise (or something like this) which uses aria2c to download files using Medialink from network. What do you think about this idea? Any comments for this implementation? Dr. Poeml, please, feel free to correct me if there are any error. Obviously, any suggestion or comment will be more than welcome :-). Thanks :-) Gerard [1] http://en.opensuse.org/Libzypp/Failover [2] http://svn.opensuse.org/svn/zypp/trunk/libzypp/zypp/media/MediaCurl.h [3] http://download.opensuse.org/distribution/10.3/repo/oss/suse/repodata/prima… [4] http://www.metalinker.org/ [5] http://download.opensuse.org/distribution/10.3/repo/oss/suse/repodata/prima… [6] http://aria2.sourceforge.net/ [7] http://svn.opensuse.org/svn/zypp/trunk/libzypp/zypp/media/MediaAccess.cc -- To unsubscribe, e-mail: zypp-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: zypp-devel+help(a)opensuse.org

[zypp-devel] zypper exclude-by-arch?
by snowcrash+opensuse 27 May '08

27 May '08

hi, i'm trying to exclude install/update by Arch. package-name wildcards work fine. e.g., adding *32bit* to /etc/zypp/locks works as expected. afaict, there's no manpage mention of arch/locks. trying, *i586* is simply ignored. @irc pointed me to a wiki-page http://en.opensuse.org/Libzypp/Locksfile which is rather a 'challenge' :-/ but, i do see reference to "solvable attributes", solvable attributes this attributes specifies attributes of object. Empty value mean that it restrict global_string on this value. and arch-specific, solvable_sourcearch update_collection_arch iiuc, e.g. to exlcude i586 arch, i add, solvable_sourcearch:i586 update_collection_arch:i586 to locks? can someone please verify/clarify the correct usage for excluding-by-arch, and the difference between "solvable_sourcearch" & "update_collection_arch" thanks! -- To unsubscribe, e-mail: zypp-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: zypp-devel+help(a)opensuse.org

The changelogs of installed packages was the single largest chunk of memory in old libzypp (10.3 era). Simply because it loaded all changelogs into memory during target initialization (i.e. not on demand).

[zypp-devel] PLEASE FOLLOW CONVENTIONS!!!!

OnMediaLocation & changeMedianr( unsigned val_r ) The accessor is called medianr() and all setters are called setProperty(val), then, why use changeProperty()? This forces you to look at the documentation and code is hard to deprecate. So please, dont use set_something but setSomething, getFoo() but foo() Duncan -- To unsubscribe, e-mail: zypp-devel+unsubscribe(a)opensuse.org For additional commands, e-mail: zypp-devel+help(a)opensuse.org
