I've CCed some of the maintainers of more widely used Yocto layers
to get comments on about tagging. Please add in people who I may
have missed.

For a while now, oe-core has had a yocto-X.Y tag in addition to the
release branch name. This helps users easily find the exact commit
that corresponds to the say 3.3 GA release. There have been some
omissions in tagging but Michael and Richard are adjusting the
release process so that tagging will happen more consistently.

Most yocto layers have not adopted the tagging perhaps because they
weren't aware of it so that's why I'm writing this email. Tagging
will make it easy to find the first commit for a specific release
independent of what the branching policy of a layer is. Layer
maintainers sometimes create the release branch in advance of
when oe-core is released and by adding the tag, it would make it
clear when the layer considers content to be officially released.
So the official starting point is what you are looking for? is there any
expectation to tag for dot release alignment?

Of course it's up to users to decide if they are going to follow
the HEAD of a branch or, for some reason, stick with a tagged commit
or private branch off that commit.
What's more important, tag or branch? Many layers hosted on
don't have the 'hardknott' branch.  If the discipline to create a new
branch is not their, I have a hard time believing 'tagging' will be high
on their list.

Are there any concerns about attempting to do this for yocto-3.3
and later?
Tagging in Poky has a meaning of a fully QA set of sources at a given
point of time.  It may be interpreted by users that if a tag showed up
in other layers, those layers are also fully tested.

Should we make it a requirement for yocto compliance?
I think you mean 'Yocto Compatible'.  Branching is already a requirement
IIRC as the program is against a specific branch.


Should it be a feature tested by the yocto compliance script?

Here's what's in oe-core and bitbake now:
$ cd .../oe-core.git
$ git tag -l | grep yocto-3

$ cd bitbake/
$ git tag -l | grep yocto-3
