[openFATE 305945] get rid of "symsets" in kernel package dependencies

Feature added by: Michal Marek (michal-m) Feature #305945, revision 1, last change by Title: get rid of "symsets" in kernel package dependencies openSUSE-11.2: New Priority Requester: Important Requested by: Michal Marek (michal-m) Description: Currently, the kernel rpm packages group the exported kernel and module symbols in find-provides and provide these "symsets". It has been done this way to reduce the amount of data the solver has to process. It has a number of problems though: * Moving modules around or adding symbols changes the symset checksums, so the rpm build needs symsets of the previous kernel(s) to provide both old and new checksums * changing or removing one unused or unimportant symbol means that each kmp that uses any other symbol from the same symset needs to be rebuilt Now that we have a much better solver, it's time to get rid of this and provide just the individual symbols. I created a test project in the build service: home:michal-m:kill-symsets. which rebuilds all 11.1 kmps against a normal kernel and against a kernel with symsets turned off (this kernel is built in home:michal-m:kill-symsets:changes). The size difference is rather low, total size of all the rpms on i586 and x86_64 increased by about 1.3M, installed size decreased by 2.6M (because of the removed /boot/symsets* files). Size of yum metadata increased by 1.4M. What needs to be done is to make sure that the solver can really handle this fine (-> Michael). I'm waiting for the test repos to appear on download.o.o. -- openSUSE Feature: https://features.opensuse.org/305945

[openFATE 306343] 'Pkgstars' to reward contributors
by fate_noreply＠suse.de 20 Feb '10

20 Feb '10

Feature added by: Will Stephenson (wstephenson) Feature #306343, revision 1, last change by Title: 'Pkgstars' to reward contributors Buildservice: Unconfirmed Priority Requester: Important Requested by: Will Stephenson (wstephenson) Description: In KDE we use 'dashstars' to reward those who fix build breakages. When a broken build module is fixed, the person responsible for the commit that fixed the build is awarded a 'dashstar', and an IRC bot advertises this in the developer channel with a message such as "JohnDoe fixed kdelibs (64 dashstars)" so the community sees their contribution. In addition, contributors can query their dashstar totals. A similar system for eg package build fixes or package version updates that is visible on the user's opensuse homepage and advertised in community channels (or a weekly summary mail to -project) would be a fun way to reward contributions. -- openSUSE Feature: https://features.opensuse.org/306343

[openFATE 305930] Don't increase version number if not strictly needed
by fate_noreply＠suse.de 20 Feb '10

20 Feb '10

Feature added by: Joop Boonen (worldcitizen) Feature #305930, revision 1, last change by Title: Don't increase version number if not strictly needed Buildservice: Unconfirmed Priority Requester: Important Requested by: Joop Boonen (worldcitizen) Description: As I use KDE42 and other newer packages I often do a factory update. I see that the footprint is very big. Because a package gets always rebuild when for instance a dependent library get rebuild. Even if the package is 100% the same it'll gets the same version number. If possible I would like to have binary identical packages yo keep the same version number this reduces bandwidth usage for users/mirrors and it can give people a false feeling that Linux is buggy "as so many packages need to be updated". -- openSUSE Feature: https://features.opensuse.org/305930

[openFate 305689] Allow creation of meta-repositories
by fate_noreply＠suse.de 20 Feb '10

Feature added by: Magnus Boman (MBoman) Feature #305689, revision 1, last change by Title: Allow creation of meta-repositories Buildservice: Unconfirmed Priority Requester: Important Requested by: Magnus Boman (mboman) Partner organization: openSUSE.org Description: It'd be extremely useful if it was possible to create meta-repositories in OBS. The way it would work, is that anyone could create a project in OBS, and from there, include several other projects to combine them in one meta-repository. It is kind of possible today if one use _links or _aggregate, but that either forces the entire repo to be built in the users own project, or requires a lot of disk space. A meta-repository would basically only create symlinks to the other projects (would not require any extra disk space, nor OBS resources for re-compiling everything in a "new" project) -- openSUSE Feature: https://features.opensuse.org/?rm=feature_show&id=305689

[openFate 305625] Emphasize my packages in a project maintained by me.
by fate_noreply＠suse.de 20 Feb '10

Feature added by: Pavol Rusnak <prusnak(a)novell.com> Feature #305625, revision 1, last change by Title: Emphasize my packages in a project maintained by me. Buildservice: New Requested by: Pavol Rusnak (prusnak) Partner organization: openSUSE.org Description: When I'm a maintainer of a project and also set as an explicit maintainer of a package inside this project, I'm unable to list of these packages. "My Projects" shows only affected projects and packages outside of these projects. I suggest to show emphasize such packages in Project view (package list) for example by adding icon, or showing the package name in bold. This is especially needed for Contrib repository. -- openSUSE Feature: https://features.opensuse.org/?rm=feature_show&id=305625

[openFate 305590] Virtual packages and virtual joint projects
by fate_noreply＠suse.de 20 Feb '10

20 Feb '10

Feature added by: Pavol Rusnak <prusnak(a)novell.com> Feature #305590, revision 1, last change by Title: Virtual packages and virtual joint projects Buildservice: New Priority Requester: Desirable Requested by: Pavol Rusnak <prusnak(a)novell.com> Partner organization: openSUSE.org Description: http://lists.opensuse.org/opensuse-buildservice/2008-12/msg00094.html Virtual packages and virtual joint project would be a special type of projects, that are part of a standard binary repository, but they have no source present in the project. It may have several typical use cases: Virtual dependency packages --------------------------- When a project intents to update a library to a newer version, virtual dependency packages and projects may determine packages that will have broken/changed dependencies after installing of a new library. How it should look. Either package or a project should have a new attribute: "Rebuild parent project packages" Possible values: "ignore": Rebuild only packages in this project and nothing else (just the current behavior) "rebuild broken": Rebuild parent project packages, that cannot be used with newer version any more (it typically happens for package, that require exact version it is built against, or packages that don't follow shared library packaging conventions) "smart rebuild": Rebuild packages that require package or symbol that are no more part of the output of the new package. "all dependencies": Behave just like a single repository and rebuild everything which uses the new in the build. Examples of use for particular values: "rebuild broken": Building some modules require the same version of the base package it was build with. When trying to update base package in a project, it will rebuild all such modules. "smart rebuild": Testing package poppler update: New poppler has a new soname and it requires to rebuild all packages that are linked with poppler. However it is possible to install these packages (and use shared library from the parent project), testing of the new library requires to rebuild these package with the new library). "all dependencies": Testing new core package (bison, gcc). All packages, that have this package in BuildRequires on build system will be rebuilt. Virtual package may become non-virtual. If you need to patch one of the packages to be able to rebuild it in the new repository, you have to link it physically to the joint repository. In this moment, package becomes equal to the normal link package, disabled by default. Virtual/non-virtual joint project --------------------------------- Just now, one can include two different projects, that have a disjunctive packages. Virtual joint project would determine packages that will build differently (or break) in one or another parent repository and rebuild them as a separate repository. Virtual joint project could be a separate project that contains rebuilds of packages in the intersection of both project. Virtual joint project may become non-virtual. If you need to patch one of the packages to be able to rebuild it with both projects included, you have to add it physically to the joint repository. In this moment, the joint project feature would be equal to the normal repository with "Rebuild parent project packages" set. Example: Suppose you have a testing repository of new poppler (different soname) and a multimedia:photo with a new version of GIMP (requires poppler). You can easily include both multimedia:photo and poppler test repositories, but you cannot test new gimp with a new poppler. Creating of virtual joint project will automatically detect these packages and rebuild them. There could be again the tag "Rebuild parent projects packages" with the same values as above. Benefits: Virtual packages: Now they are often substituted by links. Several years later, nobody knows, why such link was created and the link may rot there forever. Virtual joint project: It will allow to test result of a dangerous package check-in without actually doing it. -- openSUSE Feature: https://features.opensuse.org/?rm=feature_show&id=305590
