Discussion:
Git tool/command problems with YOCTO Open Source repos
(too old to reply)

Hello YOCTO people,

I would like to use standard git tool while using all the Yocto
layers. NOT only Poky repository (which, I believe, works all the way
with git tools), but as much as possible with other github proprietary
repos and layers. Since I am not able to execute git commands using
some number of proprietary repos over github.

As example, I'll use meta-bbb repository.
https://github.com/jumpnow/meta-bbb.git, after cloning the following
happens (chosen, since it has at least dozen of branches):

After cloning, I did not get anything from the following commands,
being in the root of the meta-bbb repo, namely:

[***@fedora28-ssd meta-bbb]$ pwd
/home/user/projects2/beaglebone-black/yocto-master/meta-bbb
[***@fedora28-ssd meta-bbb]$ git describe
fatal: No names found, cannot describe anything.
[***@fedora28-ssd meta-bbb]$ git tag
[***@fedora28-ssd meta-bbb]$ git checkout thud
Branch 'thud' set up to track remote branch 'thud' from 'origin'.
Switched to a new branch 'thud'
[***@fedora28-ssd meta-bbb]$ git checkout sumo
Switched to branch 'sumo'
Your branch is up to date with 'origin/sumo'.
[***@fedora28-ssd meta-bbb]$ git describe
fatal: No names found, cannot describe anything.
[***@fedora28-ssd meta-bbb]$

The rationale behind this request: git is the powerful tool which
should work and be solely used for YOCTO layers' synchronization. In
other words, YOCTO should give some tools' (namely git) unification
guidelines in some way. :-)

Thank you,
Zoran Stojsavljevic

I understand, but why is this an issue in Yocto project ? The maintainer
does not use tags and git describe is fast useless.

You should contact layer's maintainer and ask for that. Anyway, outside
poky, tags are quite unused in layers.

It is clear that a tool to maintain the layers in sync is required, but
it is quite independent how the layers (and many are proprietary layers)
are built. So you can use "repo" or "kas" (my preferred one) for that.

Hello Stefano,

I am (almost) perfectly aligned with kernel.org, and I (personally)
decided to use git. Since I start understanding importance of Linus.
Linux officers and their Linux philosophy.

Now... Answers to your email. KAS (Siemens developed tool by Jan
Kiszka and his crew) is the supplement for the fast/quick building the
YOCTO, to use ONLY rootfs. NOT kernel. NOT aligned with the git tool.
Not applicable for purposes as git.

On the other note, repo is GOOGLE tool. Promoted by them. Most of the
ARM followers (such as Toradex) use repo tool.

You say: I talk to the wrong crew. I think opposite. I am giving the
generic message via YOCTO email list, to avoid hundreds of particular
emails, so we can unify the effort. Which is not minor. Rather
opposite: major.

Since, I guess, this is of the major importance. For YOCTO survival.
The direction is one: git tool. For all YOCTO developers. IMHO.

Stefano,

You, as major official representative of U-Boot philosophy (and
Wolfgang's Denk right hand), do not take sides, rather ad-hoc
approach. For you, this topic is not important. Appreciated your help.

I am asking here for much higher awareness. YOCTO better survival in The Future.

Thank you,
Zoran

Personally I don't see why there needs to be One Blessed Tool to
manage keeping repositories in sync. There's lots of alternatives,
none of them is obviously superior to the others, and none of them
have any requirements on the repositories that they're managing.

If you want a repository management tool, then pick one and use it.

Again, I see git as superior tool. But I can speak only in my
name/this is only me.

Since with git I can do almost whatever with kernel.org (and
derivatives, all known distros) git... Very opposite to YOCTO. And I
like git, It is VERY powerful. Maybe I finally started to understand
the tool.

AS opposite, YOCTO can choose whatever they want. But I do not think
particular strategies and freedom of some choice will lead YOCTO
anywhere. Moslty referring to proprietary github YOCTO repos, in the
first place. IMHO!

Please, refer to my initial email. Not referring to Poky, I guess, the
Poky repo is equivalent to kernel.org. In other words, everything with
it can be done with git tool.

I am referring to many others, associated with github. Maybe it is
ONLY github, which does not support git tool in full extend.

So, as I said/wrote in the initial email. The concrete meta-bbb does
not support git tag, git describe.

Once I have no tags, I could not do anything with git log. And... You
can imagine.

Sorry for creating waves. No intent to offend anybody. Just a (strong) thought.

I guess, github has some significant problems supporting completely
git tool. Since I see that gitlab does support it (after reading, I
assume this is done for gitlab in full extend).

Peace!

Best Regards,
Zoran

Why does the lack of tags mean you can't do anything with git log?

Tags are simply a way of naming arbitrary commits, typically "This is
version 1.0". If a repository doesn't make releases then it doesn't
need to use tags. This isn't a problem.

as others said before, meta-bbb is a proper git tree. and for obvious
reasons, github is definitely a decent git service provider.
Post by Zoran Stojsavljevic
So, as I said/wrote in the initial email. The concrete meta-bbb does
not support git tag, git describe.
The problem you are seeing is that no git tag have been pushed to
meta-bbb, but that doesn't make meta-bbb an invalid git repo, or an
invalid OpenEmbedded layer. What we expect from OE layer is to provide
branches which track the oe-core repo (e.g. master, thud, sumo, ...),
but there is no requirement for tags.
Post by Zoran Stojsavljevic
Once I have no tags, I could not do anything with git log. And... You

Actually, no, I do not imagine. git log will work, with or without
tags. Git log will go through the history of commits, and it doesn't
need tag. Git tags are optional references that can be "attached" to
commits.

This is not correct. I hope the clarifications above would be helpful.
github definitely supports git very well, so does gitlab.

This is what your opinion is. Which seems to be vastly overestimating its own importance.
I do not think you understood what I am trying to advertise. The
unification. In other words:
If I use kernel.org, I use git tool.
If I use YOCTO Poky, I would like to use git tool.
For all YOCTO repos, I would like to use git tool.

Not repo, kas, or other tools. Not particular tools, assigned to
particular tasks, for particular build systems.

Since I would like to invest time and effort in ONLY one,
comprehensive tool, and discard all other tools which are not up to
the complex challenges I have. So this is why I sent initial email, in
first place,

Thank you,
Zoran

Hi Zoran,
Post by Zoran Stojsavljevic
Hello YOCTO people,
I would like to use standard git tool while using all the Yocto
layers. NOT only Poky repository (which, I believe, works all the way
with git tools), but as much as possible with other github proprietary
repos and layers. Since I am not able to execute git commands using
some number of proprietary repos over github.
As example, I'll use meta-bbb repository.
https://github.com/jumpnow/meta-bbb.git, after cloning the following
After cloning, I did not get anything from the following commands,
/home/user/projects2/beaglebone-black/yocto-master/meta-bbb
fatal: No names found, cannot describe anything.
I understand, but why is this an issue in Yocto project ? The maintainer
does not use tags and git describe is fast useless.
You should contact layer's maintainer and ask for that. Anyway, outside
poky, tags are quite unused in layers.
Post by Zoran Stojsavljevic
Branch 'thud' set up to track remote branch 'thud' from 'origin'.
Switched to a new branch 'thud'
Switched to branch 'sumo'
Your branch is up to date with 'origin/sumo'.
fatal: No names found, cannot describe anything.
The rationale behind this request: git is the powerful tool which
should work and be solely used for YOCTO layers' synchronization. In
other words, YOCTO should give some tools' (namely git) unification
guidelines in some way. :-)
It is clear that a tool to maintain the layers in sync is required, but
it is quite independent how the layers (and many are proprietary layers)
are built. So you can use "repo" or "kas" (my preferred one) for that.
Best regards,
Stefano Babic

OK, I rest my case. Seems, that I am the only one here using git
describe, and git log using tags.

Could be. ;-)

You mean OpenEmbedded Layers, not Yocto repo here. I think 99.9%
(maybe 100%) of the public OE layers are available as git repo. So you
can (in fact you have to) use git for any OE layer.
Post by Zoran Stojsavljevic
Not repo, kas, or other tools. Not particular tools, assigned to
particular tasks, for particular build systems.
I think you are confused. There are hundreds of OE layers out there,
maintained by developers, companies, communities, ... Poky is a
reference implementation maintained by the Yocto Project. Building a
custom Linux distro using Yocto Project means that you need to pull a
certain amount of layers based on what you are doing. Most of the time
each of these layers are hosted in their own *git* tree. For Poky we
create a *new* git tree that results of the "merge" of all the
dependent layers. However the OE core is maintained in their own tree
and bitbake as well.

the tools you mentioned here, like repo, kas, .. are not equivalent to
git. they are helpers, wrappers, tools that can be use to combine many
individual git repo to form a single workspace, so that you have all
the layers you need in a single workspace to build your own custom
distro.

The Yocto Project does not recommend any specific tool to create such
workspace, and people are using various solutions. There are on-going
discussions in YP/OE to pick one tool and promote it, but no
conclusion so far.

But again this is very different from the initial problem you are
reporting, which is just a misunderstanding of git tags and commits.

Nicolas,

Your problem is that you are too emotional. Period. I clearly
explained what my problem is. For some YOCTO github repos, certain git
commands DO NOT work. Nothing I did misunderstand, you just do not
read my emails enough carefully. If you go back on on my initial
email, and try it yourself, you'll see that there are commands which
are not working. Such as git describe, or git tag.

Here is the description of git tag commands. For you to learn (please,
read it carefully and exercise on the given example):
https://www.atlassian.com/git/tutorials/inspecting-a-repository/git-tag

Before writing nonconclusive accusations, please, check what I am
writing above, on my initial email. Maybe I am doing something wrong,
but I do not think so. For me, kernel.org tree perfectly works, and it
is perfectly aligned with git commands and .git directory.

With ALL git commands I am using.

Thank you,

First, I don't think I have a problem on this specific topic. And then

Myself and a few others have tried to explain that these commands work
perfectly well actually, unlike what you think. When running "git tag"
on a repo that does not have any tag, it just doesn't return anything,
so what you are seeing is the proper behavior. Same thing with "git
describe". So the problem with the repo you have mentioned is that
there is no tag published. That's it. Nothing wrong with git, or
github, or Yocto.

maintained by developers, companies, communities, ... Poky is a
reference implementation maintained by the Yocto Project. Building a
custom Linux distro using Yocto Project means that you need to pull a
certain amount of layers based on what you are doing. Most of the time
each of these layers are hosted in their own *git* tree. For Poky we
create a *new* git tree that results of the "merge" of all the
dependent layers. However the OE core is maintained in their own tree
and bitbake as well.
the tools you mentioned here, like repo, kas, .. are not equivalent to
git. they are helpers, wrappers, tools that can be use to combine many
individual git repo to form a single workspace, so that you have all
the layers you need in a single workspace to build your own custom
distro.
The Yocto Project does not recommend any specific tool to create such
workspace, and people are using various solutions. There are on-going
discussions in YP/OE to pick one tool and promote it, but no
conclusion so far.
But again this is very different from the initial problem you are
reporting, which is just a misunderstanding of git tags and commits.

Since I would like to invest time and effort in ONLY one,
comprehensive tool, and discard all other tools which are not up to
the complex challenges I have. So this is why I sent initial email, in
first place,
Thank you,

Hello Zoran,

I am (almost) perfectly aligned with kernel.org, and I (personally)

You are free to choose your workflow as you please.

Now... Answers to your email. KAS (Siemens developed tool by Jan
Kiszka and his crew) is the supplement for the fast/quick building the
YOCTO, to use ONLY rootfs. NOT kernel. NOT aligned with the git tool.
Not applicable for purposes as git.
It is a tool that serves one purpose. It does that job well.
Post by Zoran Stojsavljevic
On the other note, repo is GOOGLE tool. Promoted by them. Most of the
ARM followers (such as Toradex) use repo tool.
Thats what they choose.
Post by Zoran Stojsavljevic
You say: I talk to the wrong crew. I think opposite. I am giving the
generic message via YOCTO email list, to avoid hundreds of particular
emails, so we can unify the effort. Which is not minor. Rather
opposite: major.
Since, I guess, this is of the major importance. For YOCTO survival.
The direction is one: git tool. For all YOCTO developers. IMHO.
This is what your opinion is. Which seems to be vastly overestimating
its own importance.

Stefano,
You, as major official representative of U-Boot philosophy (and
Wolfgang's Denk right hand), do not take sides, rather ad-hoc
approach. For you, this topic is not important. Appreciated your help.
By now, you are telling other people who have been doing thwir work
successfully for decades how to do their jobs.
Actually, telling off one of the core contributors and community members
with "This is not for you" is plain rude.
Post by Zoran Stojsavljevic
I am asking here for much higher awareness. YOCTO better survival in The Future.
We are doing quite well at the moment, thank you.
So if you have a proposal on how to improve things, feel free to share
it. Go ahead and lead on how to use that proposal by doing your own
upstream work, showing how emplying your proposal makes it better and
more usable.
Just getting onto a mailing list and saying "You're doing it wrong
because it doesn't suit my workflow", again, is quite rude.
Greetz.
PS: yes, this mail is explicitly meant to support Stefano.

Hi Zoran,

Hello YOCTO people,
I would like to use standard git tool while using all the Yocto
layers. NOT only Poky repository (which, I believe, works all the way
with git tools), but as much as possible with other github proprietary
repos and layers. Since I am not able to execute git commands using
some number of proprietary repos over github.
As example, I'll use meta-bbb repository.
https://github.com/jumpnow/meta-bbb.git, after cloning the following
After cloning, I did not get anything from the following commands,
/home/user/projects2/beaglebone-black/yocto-master/meta-bbb
fatal: No names found, cannot describe anything.
I understand, but why is this an issue in Yocto project ? The maintainer
does not use tags and git describe is fast useless.
You should contact layer's maintainer and ask for that. Anyway, outside
poky, tags are quite unused in layers.
Post by Zoran Stojsavljevic
Branch 'thud' set up to track remote branch 'thud' from 'origin'.
Switched to a new branch 'thud'
Switched to branch 'sumo'
Your branch is up to date with 'origin/sumo'.
fatal: No names found, cannot describe anything.
The rationale behind this request: git is the powerful tool which
should work and be solely used for YOCTO layers' synchronization. In
other words, YOCTO should give some tools' (namely git) unification
guidelines in some way. :-)
It is clear that a tool to maintain the layers in sync is required, but
it is quite independent how the layers (and many are proprietary layers)
are built. So you can use "repo" or "kas" (my preferred one) for that.
Best regards,
Stefano Babic

Each project has its own configuration management, nowadays mostly git.
But OE can use git / mercury / subversion. Your initial question is
quite a complain why tags are not used in OE, and git describe does not
work. Nevertheless, because layers are not part as a single big repo,
you need some way to sync the layers. kas is one of these tools.

There are people happy working with repo. Everybody chooses the tool

On the other note, repo is GOOGLE tool. Promoted by them. Most of the
ARM followers (such as Toradex) use repo tool.
fwiw, I suggest to use just the plain 'git submodule'. It works perfectly
to build a BSP and uses a native git workflow. E.g. look at

https://gitlab.com/ensc-groups/bpi-router/BSP

A plain 'git clone --recursive' will download the complete BSP and you
can use 'git remote update --remote' to synchronize layers.


Google 'repo' is crap and adds only a very small value (better mirroring
and 'repo grep') compared to submodules.

Zoran,

This is normal behaviour for git repositories with no tags. Git
describe just describes the latest annotated tag and if there is none,
then it of course, can't describe anything. Generally, this is up to
the repo maintainer to define tagging policy (I think all we do in
OE/YP is ask for named release branches). So this isn't something
that is "broken" it's just not asked of layer maintainers. I'm not
sure why you need git describe in your workflow, but you could easily
write something that reverts to something like `git shortlog -1` or
something on repos that return fatal on a git describe.

I'm not sure what the request is here. To ask all the repository
maintainers to add tags so you don't return a fatal on git describe?

Not quite. To add tags, yes, NOT for git describe (it is just a test).
Rather for git log (using tags).
