Dear release team, I would like to request a transition slot for glibc 2.43. It has been available in experimental for a few months and appears to be in good shape. It has built successfully on all release architectures and on most ports architectures. One important change that causes compatibility issues is that, when using the C23 standard (default with GCC 15), the functions bsearch, memchr, strchr, strpbrk, strrchr, strstr, wcschr, wcspbrk, wcsrchr, wcsstr and wmemchr now return a pointer to a const-qualified type when the input argument is a pointer to a const-qualified type. A possible quick workaround if we need to fix a package for the transition is to force the ISO C level with -std=c17 or -std=gnu17 or use GCC 14. An archive rebuild has been done, and the corresponding bugs have been reported [1], as well as the ones causing autopkgtest failures. We are now down to less than 40 bugs. On the autopkgtest side, the experimental pseudo-excuses look good overall, and the remaining ones due to the C23 change, issues in unstable or britney selecting the wrong set of packages. As glibc is using symbol versioning, there is no soname change. That said a few packages use internal libc symbols and have to be rebuilt for this transition. Here is the corresponding ben file: title = "glibc"; is_affected = .depends ~ /libc[0-9.]* \(<</; is_good = .depends ~ /libc[0-9.]* \(<< 2.44\)/; is_bad = .depends ~ /libc[0-9.]* \(<< 2.43\)/; Speaking about migration, this glibc version adds a few new GLIBC_2.43 symbols, to support ISO C23 (free_sized, free_aligned_sized, memset_explicit and memalignment), and to wrap to Linux kernel syscalls (mseal and openat2). These symbols are unlikely to be used widely at this stage, and thus this transition should not block many packages to migrate to testing. Thanks for considering.
