https://fedoraproject.org/wiki/Changes/GLIBC229 == Summary == Switch glibc in Fedora 30 to glibc version 2.29. == Owner == * Name: [[User:Codonell|Carlos O'Donell]] * Email: carlos@xxxxxxxxxx * Release notes owner: carlos@xxxxxxxxxx == Detailed Description == The GNU C Library version 2.29 will be released at the beginning of February 2019; we have started closely tracking the glibc 2.29 development code in Fedora Rawhide and are addressing any issues as they arise. Given the present schedule Fedora 30 will branch after the GLIBC 2.29 upstream release. However, the mass rebuild schedule means Fedora 30 will mass rebuild (if required) after GLIBC 2.29 upstream freezes ABI for release, so careful attention must be paid to any last minute ABI changes. == Benefit to Fedora == Stays up to date with latests security and bug fixes from glibc upstream. == Scope == * Other developers: Developers need to ensure that rawhide is stable and ready for the Fedora 30 branch. Given that glibc is backwards compatible and we have been testing the new glibc in rawhide it should make very little impact when updated. * Release engineering: https://pagure.io/releng/issue/7907 * Policies and guidelines: The policies and guidelines do not need to be updated. * Trademark approval: Not needed for this change == Upgrade/compatibility impact == The library is backwards compatible with the version of glibc that was shipped in Fedora 29. Some packaging changes required, see: https://sourceware.org/glibc/wiki/Release/2.29#Packaging_Changes We fully expect to fix all packaging changes in Fedora Rawhide given that glibc in Rawhide is tracking what will become glibc 2.29. == How To Test == The GNU C Library has its own testsuite, which is run during the package build and examined by the glibc developers before being uploaded. This test suite has 5900+ tests that run to verify the correct operation of the library. In the future we'll also be running the microbenchmark to look for performance regressions as well as behavioural ones. == User Experience == Users will see improved performance, many bugfixes and improvements to POSIX compliance, additional locales, etc. The glibc 2.29 NEWS update will include more details. == Dependencies == All packages do not need to be rebuilt. == Contingency Plan == * Contingency mechanism: Given that Rawhide has started tracking glibc 2.29, no show-stopper problems are expected. At this point, we can still revert to upstream version 2.28 if insurmountable problems appear, but to do so may require a mass rebuild to remove new symbols from the ABI/API. * Contingency deadline: Upstream ABI freeze deadline of 2019-01-01. == Documentation == The glibc manual contains the documentation for the release and doesn't need any more additional work. == Release Notes == * Release Notes tracking: <will be assigned by the Wrangler> The GNU C Library version 2.29 will be released at the beginning of February 2019.
