Goal
The goal is to rebuild every single Fedora package, regardless of content, before the Fedora 11 Feature Freeze (March 3rd).
Driving Features
This requires a change in redhat-rpm-config for the i586 flags, as well as a koji config change to build for i586 rather than i386 by default. These two changes can happen at any time, and will likely happen this week to shake out any bugs. Dennis Gilmore and Jon Masters are responsible for getting these changes in place.
This requires gcc 4.4.0-0.19 in the buildroots before the mass rebuild begins. Jakub is responsible for getting this built this week.
This requires redhat-rpm-config changes for default hash, as well as koji code changes to handle the hash. Mike Bonnet and Miloslav Trmač are responsible for getting the koji changes done upstream. Miloslav Trmač and Jon Masters are responsible for getting the redhat-rpm-config changes in place, which depend on the koji changes being live first. A koji outage is scheduled for this weekend to deploy a new version of koji, which will include changes for this feature. An updated redhat-rpm-config will be deployed shortly thereafter to ensure hash changes are in effect.
Schedule
Given the changes required for the above features and the given schedules, Release Engineering will be ready to start scripted rebuilds on Monday Feb. 23rd. All rebuilds should be finished prior to the Feature Freeze, which is March 3rd.
Opting Out
Release Engineering has given maintainers the ability to opt-out of the scripted rebuild in order to do the build on their own. Note that every single package needs to be rebuild, regardless of the contents.
In order to opt-out of the scripted rebuild, a maintainer will need to check a file into their package's devel/ branch, named noautobuild. This file should contain a short rationality of why you wish to do the build yourself.
If the build initiation script encounters such a file, it will skip that package. However, given the tight deadlines (Feature freeze being the 3rd of March), a very short grace period will be given for completing the builds on your own. If your build has not been attempted by the 26th of Feb, the script will no longer honer the noautobuild request and will attempt to rebuild your package. If, however, a rebuild has been attempted, the script will bypass your module. This should prevent multiple attempts to build something that fails for one reason or another.
Scripts
Release Engineering has created two scripts. One is to initiate the builds, and the other is to query for items still needing to be built.
Build Initiation
The rebuild script works in the following way:
Generate a list of all packages in dist-f11 Loop through each package: Query if a build has already been attempted/completed since koji changes went live. If so, move to next package If not, check out CVS Check for a noautobuild file If so, move to next package If not, rpmdev-bumpspec cvs commit;tag make (background) build Move on to next package
Each step will have some error catching and logging so that people can clean up the various failures for whatever reasons. The builds will be background builds, which will allow other builds done to take higher priority when a builder has a free slot. However maintainers should take care when doing this so that the background build won't take 'latest' president when it finishes. Asking rel-eng to kill the scripted build will typically be enough.
Status Query
Release Engineering has developed a script to query dist-f11 and report on packages that have yet to be rebuilt. Results of these queries will be delivered to various places, yet to be determined, broken down by maintainer for easier discovery of work needed.
