Current status
- Targeted release: Fedora 21
- Last updated: 2014/04/01
- Tracker bug: <will be assigned by the Wrangler>
Detailed Description
The current upstream repository contains several improvements that need to get released and integrated into Fedora:
- Support for weak dependencies
- Support for files > 4GB
- New API for accessing files and file contents
- New tool for converting rpm packages to tar files
- Internal plugin interface
- Improved SELinux handling
Updating to the new version will allow using these features in the upcoming Fedora releases.
Benefit to Fedora
The above plus closing the gap between RPM upstream and the Fedora version.
Scope
- Proposal owners: The RPM code base needs to get stabilized and release ready. The release candidates need to be tested in rawhide.
- Other developers: Will test the release candidates during normal operation in raw hide. Need to report issues and bugs.
- Release engineering: Check infrastructure for compatibility. Check for 64bit readiness as soon as builders are updated, too (F22 time frame).
- Policies and guidelines: Packaging policies might need reconsidering in the light of the new options (F22 or even F23 time frame).
Upgrade/compatibility impact
Using some of the new feature may break forward compatibility. Backward compatibility is expected to be kept.
How To Test
Testing is done in full operation.
User Experience
- Packagers will be able to package files >4GB
- Packagers will be able to use weak dependencies
- API users will be able to access file data more cleanly and access payload data for the first time
- XXX SELinux
Dependencies
- Weak dependencies need to be supported by create_repo, and the updaters (and may be the packaging policy) to be useful
- >4GB support requires the infrastructure to support those file sizes to be usable. Especially it requires the builders to be updated to rpm-4.12, too
Those features not being useful from the start is not a blocker for the change, though. Actual use of those features can (and is expected to) be postponed to upcoming Fedora releases.
Contingency Plan
Go back to rpm-4.11. This may require reverting some changes to other packages (in case they are already using some of the new features). But it is not expected to happen on a large scale - if at all.
