- Percentage of completion: 100%
- Rpm 4.10.0 final in rawhide, dependent packages rebuilt
The RPM development team would like to update Fedora RPM to a pre-release version of 4.10 as early as possible to leverage the wider testing that Fedora rawhide gets. A stable upstream version of the new RPM is expected to be released well in time before Fedora 18 alpha. This is more of a "time-based code outlet" release than one with many new fancy features.
Benefit to Fedora
The full change summary (draft) can be found at http://rpm.org/wiki/Releases/4.10.0, but some of the immediate benefits to Fedora are
- Performance improvements
- Automatic SELinux policy reload on policy changes
- Improved robustness: improved file conflict detection, more thorough input validation, added error checking and handling etc.
- Many bugfixes all over the place
4.10.0 also adds support for dpkg-style tilde-versions where eg 1.0~pre1 is considered older than 1.0, which makes handling upstream pre-release versions much easier. However this can not be utilized in Fedora before the entire package management stack, including the buildsystem, has been updated to support it.
Packages directly linking to librpm need to be rebuilt due to soname change, but no other rebuilds are necessary as no new package-level incompatibilities have been introduced.
From upstream POV there are no big hurdles expected in reaching 4.10 stable from current situation: some loose ends to tie up and basic shakedown after a fairly large amount of internal changes.
How To Test
Rpm has it's own test-suite which gets executed during the package build. Beyond that, rpm gets quite thoroughly tested in the course of "everyday activities" such as system installation, upgrades and package building.
- The new RPM changes very little in the average "user experience":
- Somewhat faster operation
- Some annoying bugs have been fixed
- Dependencies are unchanged from rpm-4.9.x.
- Revert to rpm 4.9.x. As there are no database- or other package-level incompatibilities introduced in this version, reverting would be a simple matter of bumping epoch and rebuilding the packages linking to librpm.
