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 (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.
