The goal is to rebuild every single binary Fedora package, for fedora 21 and 22. the reason is due to a miscompilation bug in GCC (see GCC Bug for more details)
Given the changes required for the above features and the given schedules, Release Engineering will be ready to start scripted rebuilds on Friday, August 15th. All automated rebuilds should be finished by the end of the weekend. Any clean-up manual rebuilds should be finished before Beta change deadline and will need Bodhi updates.
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.
The rebuild script works in the following way:
use list of packages in f22 that are archeful 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 git check master and f21 git hashes if master or git hashes dont match rpmdev-bumpspec else git merge master fedpkg commit -cp fedpkg (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' precedent when it finishes. Asking rel-eng to kill the scripted build will typically be enough.
Once the rebuild script has finished, another script will run to tag the builds into f21. This script will check that a newer build hasn't been done or started in f21 since the scripted rebuild was submitted. This will protect against the scripted rebuild overriding an even newer build done while the scripted rebuild was waiting in the background.
Release Engineering has developed a script to query f21 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.
- Maintainers that wish to do their own builds should read the Opting Out section.
- Maintainers can help this effort by ensuring rpmdev-bumpspec correctly bumps your package's spec files.
- Maintainers should ensure that their packages currently build from source.
- Maintainers should ensure that there are no unwanted changes committed to git but not built yet.
Frequently Asked Questions
When will my own build "count" for the rebuild?
After the last piece needed for thee mass rebuild a gcc build was put into place, a build done by a maintainer will "count" toward the rebuild. 2014-06-05 00:00:00 is the UTC time that builds count from
Will the rebuilds be ordered?
Currently there is no plan to logically order the rebuilds based on deps. The ordering will be alphanumerical based on package name. There are no planned ABI/soname changes that would require logical build ordering. Further, all the builds will be kept in a special tag (f21-rebuild) until the whole run is done, and then they will be tagged into f21 in one shot to minimize the shuffle of buildroot contents during the rebuilds.
