reassign 498274 buildd.emdebian.org notfound 498274 1.4.6 tag 498274 + confirmed tag 498274 + help retitle 498274 Coordination of testing migrations in Emdebian thanks
All Emdebian flavours need to coordinate migrations into testing - preferably together with migrations of the toolchain packages and the tools themselves. i.e. the debian/, emdebian/, grip/ and locale/ repositories should migrate all binaries from the relevant source package(s) at the same time and maintain installability for each. If a particular binary is not available, Emdebian needs to have guidelines on whether the entire migration is paused or certain flavours are allowed to migrate ahead of the rest. 1. filter/ updates via a daily cron task, directly from Debian. 2. grip/ updates a short time later - after the packages are built on the server. 3. locale/ needs better coordination between Grip and Crush but reprepro handles the current duplication without problems. Generally, locale/ will be updated by the Grip builds quicker than the Crush builds. 4. emdebian/ (which probably should be renamed/symlinked as crush/) migrations are not currently automated, although information necessary to perform the migration is collated daily with a 24hr delay. Packages that fail to cross-build after an update in Debian will take longer to fix but most fixes are done within the 10day testing migration delay. There probably needs to be a system to alert the mailing list when a package consistently fails to cross-build. 5. debian/ (i.e. toolchains) take the longest to build and fix when the build fails but as long as all toolchains remain installable, it probably isn't necessary to delay the migration of other flavours simply because the toolchain is delayed. 5.1. Tools (also in debian/) like emdebian-tools and apt-cross are managed via Debian and Britney - releases only build up in debian/ during a release freeze, as now. Migrations within debian/ must avoid migrating packages other than those necessary for the toolchains. The 'filter/' repository maintained by emdebian-grip-server can provide all the data we need about migrations within Debian - support already exists such that when the chosen mirror updates, the filter is updated by a cron task and the Packages.gz file in the filter repository is updated by reprepro. This removes the need to listen to the email announcements from Britney or devise other ways to monitor Debian testing. This is a Policy thing for Emdebian - it will be supported via scripts but the implementation needs to be bespoke. Debian::Packages::Compare will be the main agent, tying the TDebs to the source packages via the Source: field of the TDeb. Of course, this problem would go away if there was a way to get these repositories into the main Debian archive. :-) Alternatively, if the real 'britney' script becomes available as a regularly updated package in Debian, it could be possible to use that with reprepro. This could be a good sub-project for someone else to develop. It will be essential when Crush starts to support more architectures. If you want to work on it, just claim this bug report and keep it (and therefore the mailing list) regularly updated. -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
