Cover letter [Buildroot] [PATCH v3 0/7] glibc: bump to 2.26

Arnout, All,

Let's hope that glibc 2.26.1 will be released soon :)

As discussed on IRC:

Apparently there won't be a glibc 2.26.1. It's up to distros to pick a git
commit to release.

Yep, this is just silly... :-(

Quoted 4 lines

So we have the choice to either keep a lot of patches in Buildroot, or use a git download instead of a tarball. The latter has the disadvantage of having a silly version "number" (the sha1), and that git downloads are generally much slower.

If we want a slightly less-silly-looking version, we could use something like:

    glibc-2.26-43-gfdf58eb

whichh means the sha1 'fdf58eb' that is '43' commits after the 'glibc-2.26' tag. But we have to be careful about shortening the sha1, to avoid collisions. I would say that we stay with the full sha1.

It is pretty easy to generate such a version string:

    git describe --match 'glibc-*' --abbrev=12 origin/release/2.26/master
Quoted 1 line

For now, we have those 6 patches in Buildroot. This may change in the future.

I would say that we should switch to using the 2.26/master branch from upstream, because we don;t have the bandwidth to assess whether we need/want to backport individual patches.

If upstream commits on the maintenance branch, it means that it is a fix. And we want fixes, whatever they fix: functionality or security.

So I'd say we should switch to git. The repo is even accessible through https (although it is not documented): https://sourceware.org/git/glibc.git

Regards,
Yann E. MORIN.
