GLIBC 2.18

Summary

Switch GLIBC in Fedora 20 to GLIBC version 2.18

Owner

Current status

Detailed Description

GLIBC 2.18 will be released at the end of July 2013; we have started closely tracking the GLIBC 2.18 development code in Fedora Rawhide and are addressing any issues as they arise. There should be little difference from the users perspective between GLIBC 2.17 used in F19 and GLIBC 2.18 used in F20.

Benefit to Fedora

Stays up to date with latests bug fixes from glibc.

Scope

  • Proposal owners: Update glibc to 2.18 from tested upstream release.
  • Other developers: N/A (not a System Wide Change)
  • Release engineering: N/A (not a System Wide Change)
  • Policies and guidelines: N/A (not a System Wide Change)

Upgrade/compatibility impact

The library is backwards compatible with the version of glibc that was shipped in Fedora 19.

How To Test

GLIBC has its own testsuite, which is run during the package build, plus many other packages with automated tests also help to test the new GLIBC.

User Experience

Users will see improved performance, many bugfixes and improvements to POSIX compliance, additional locales, etc.

Dependencies

All packages do not need to be rebuilt.

Contingency Plan

  • Contingency mechanism: Given that Rawhide has started tracking GLIBC 2.18, no show-stopper problems are expected. In the unlikely event a major problem were discovered, we could fall back to the older GLIBC 2.17 from Fedora 19.
  • Contingency deadline: N/A (not a System Wide Change)
  • Blocks release? N/A (not a System Wide Change), No

Documentation

The glibc manual contains the documentation for the release and doesn't need any more additional work.

Release Notes

The glibc 2.18 NEWS file will contain all the relevant release notes and will be available once 2.18 is released in the next couple of weeks (2013-07-08). You can see the current NEWS entry here: http://sourceware.org/git/?p=glibc.git;a=blob_plain;f=NEWS;hb=HEAD
