= Proposed System Wide Change: The GNU C Library version 2.28 = https://fedoraproject.org/wiki/Changes/GLIBC228 Owner(s): * Carlos O'Donell <carlos at redhat dot com> Switch glibc in Fedora 29 to glibc version 2.28. == Detailed description == The GNU C Library version 2.28 will be released at the beginning of August 2018; we have started closely tracking the glibc 2.28 development code in Fedora Rawhide and are addressing any issues as they arise. Given the present schedule Fedora 29 will branch after the GLIBC 2.28 upstream release. However, the mass rebuild schedule means Fedora 29 will mass rebuild (if required) just after GLIBC 2.28 upstream freezes ABI for release, so careful attention must be paid to any last minute ABI changes. This change also includes the following changes: * IBM POWER LE transition to Float128 for long double. [https://fedoraproject.org/wiki/Changes/PPC64LE_Float128_Transition] == Scope == * Proposal owners: Update glibc to 2.28 from tested upstream release. * Other developers: Developers need to ensure that rawhide is stable and ready for the Fedora 29 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: #7475 [https://pagure.io/releng/issue/7475]: The Fedora Toolchain team is responsible for ensuring that Fedora Rawhide stabilizes ABI before a Fedora release, or that after the branch that the Fedora release is rebased (a very small rebase) to the final released version. This is a requirement for Fedora to inherit the ABI and API guarantees provided by upstream. If a mass rebuild is required by glibc or other components, the Fedora Toolcahin team will ensure coordination with release engineering such that a mass rebuild uses the released version of glibc to fix any last minute ABI changes. A mass rebuild is not required and this is communicated to release engineering. ** List of deliverables: * Policies and guidelines: The policies and guidelines do not need to be updated. * Trademark approval: Not needed for this change -- Jan Kuřík JBoss EAP Program Manager Red Hat Czech s.r.o., Purkynova 99/71, 612 45 Brno, Czech Republic _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://getfedora.org/code-of-conduct.html List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@xxxxxxxxxxxxxxxxxxxxxxx/message/XOFGJVTX3RSJALZ7HYATRIPPWCQQWLGA/
