** Description changed: ## FFE ## ## Rationale glibc 2.43 introduces several changes, including many architecture-specific optimizations of math functions, a few new functions, a few deprecations, some changes to ISO C32 related to correctness, updated Unicode, and around 80 bugfixes. This FFE requests merging glibc 2.43 in Resolute. There is no expected transition associated with this version. The merge was delayed due to the release date (Jan 23, 2026), the riscv issue (LP: #2142067), and avoiding conflict with the many transitions - in flight. - + in flight. Considering how late in the cycle we are, I'm deferring the decision + to do the upload to the release team. ## Testing glibc 2.43 has been built and tested on all supported architectures. autopkgtest have been run. Identified FTBFS (from a pre-release snapshot, in December) were recently rebuilt in ppa:~simpoir/glibc-no-rvv-memset Autopkgtest has been successfully run against that ppa for a few of those packages. Apart to the riscv64 regression which has been addressed, and C23 FTBFSes, no other regression has been observed. - ## Regression potential The upstream changes to add const returns to ISO C23 functions causing FTBFs, are already being addressed for packages in main, even prior to upload: https://bugs.launchpad.net/ubuntu/+bugs?field.searchtext=ISO+C23&field.status%3Alist=NEW&field.status%3Alist=CONFIRMED&field.status%3Alist=TRIAGED&field.status%3Alist=INPROGRESS&&field.status%3Alist=FIXCOMMITTED&field.status%3Alist=FIXRELEASED From December's rebuild, about 50 packages in universe have been identified to fail building from C23 const addition. Although the new error is generally trivial to fix, either by adding const to declarations or casting out (if safe), many of those packages have not yet been fixed and will fail to rebuild. Most of those are already tracked in Debian. The current lack of autopkgtest infrastructure for riscv64 could hide other regressions tied to the new riscv changes. Only limited testing has been done for that architecture, mostly upgrading, rebuilding packages, and synthetic usage in local VMs. - ## Additional Information Complete changelog: https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS;hb=refs/tags/glibc-2.43
