GCC 14 is still in development, but it has a wonderful new feature in its static analyzer (-fanalyzer).

It can now draw beautiful Unicode diagrams showing exactly how you went out-of-bounds.

See https://inbox.sourceware.org/gcc-patches/20230531180630.3127108-1-dmalcolm@redhat.com/ too.

Thank you to the wonderful David Malcolm for implementing this - who also does a tonne of work with mentoring for GCC's GSoC programme, and working on docs to help new people get into GCC: https://gcc-newbies-guide.readthedocs.io/en/latest/index.html.

Today, we changed the default recommended filesystem in the #gentoo handbook from ext4 to xfs.

XFS is robust and has all the niceties of ext4 (modulo shrinking) but with modern features on top.

(It helps that xfsprogs doesn't have weird endianness bugs too..)

btrfs is of course another option for the future but our users are conservative in some respects, and baby steps > none.

The main benefit of this is reflinks and copy_file_range which automatically takes advantage of that.

Now, as for using it.. 🧵
