Update RPM to 4.9


Update RPM to 4.9 in Fedora 15.


Current status

  • Targeted release: Fedora 15
  • Last updated: 2010-08-12
  • Percentage of completion: 0%

Detailed Description

The RPM development team would like to update Fedora RPM to a pre-release version of 4.9 as early as possible to leverage the wide testing that Fedora rawhide and beta releases get. A stable upstream version of the new RPM is expected be released well in for Fedora 15 alpha.

Benefit to Fedora

The full description can be found in http://rpm.org/wiki/Releases/4.9.0 (Draft)

The most visible improvements over previous versions:

  • Pluggable & much more flexible dependency generator
  • Further performance improvements
  • Many bugfixes all over the place



Test Plan


User Experience

  • The new RPM changes very little in the average "user experience":
    • Faster installs/upgrades
    • Some annoying bugs have been fixed


  • No new dependencies.

Contingency Plan

  • Revert to 4.8. The packaging changes somewhat with 4.9, complicating downgrades. Also a manual 'rpm --rebuilddb' would be required after downgrades so this is a very last-resort option (although it would only affect rawhide users).
  • Avoid depending on new 4.9 features until final acceptance is gained.
