As one of the people in charge of maintaining the git repo, I would like to
avoid having, as Darren suggested, a whole bunch of -contrib repos. However,
maybe I'm missing something here, as I think basic git solves this issue:

Use Case: Tomz has a branch of meta-intel that he has pushed to
poky-contrib.git:tomz/foo. dvhart wants to look at it from his local repo:
I'm curious how many people reading this feel this is "basic git". Anyone
willing to admit this was the first time they have seen a targeted branch
fetch used to avoid a larger download? If everyone is comfortable with this,
fine. If not, we should consider the impact of this type of access on our
users.

git remote add poky-contrib ssh://git@.../poky-contrib.git
git fetch poky-contrib tomz/foo:foo
git checkout foo
My biggest complaint with this is the lack of self discovery from within git
without doing a git remote update. Unless tomz is online at the time to tell me
it's tomz/foo-bar, not tomz/foo_bar, then I have to go load the web browser and
check which branches are available, or resort to downloading all the objects.

I just realized another major issue I have with this approach. It
doesn't just mean that I _can_ use git fetch to get a specific branch to
avoid pulling in a massive pile of objects I don't need, it means I have
to stop using "git remote update" entirely for everything else I do in
that repository and I have to fetch all the other branches manually. The
recommended approach here is VIRAL.

I confess though, it still just feels wrong to keep unrelated source trees in
the same repository.


The fetch allows a sparse checkout of *just* tomz's branch. No need to
download all 75M of poky-contrib which is what you would do with "git remote
update". Git remote update is the wrong way to do this and I'd like to avoid
having to swap infrastructure around when it seems to me that this is just
one of those "git being a pain to learn"
Just to add to this discussion, with gitolite, it should be easy to
setup a yocto-contrib repo where each user "owns" the branches under
<keyname>/*. This means as ssh keys are added, they'd automatically get
their own "scratch" area. As Beth points out above, its perfectly
possible to checkout branches and manipulate them as long as you know
the commands.

This isn't a set of repos per user but when you think about this, how
often do we really need that? Yes, some people like Bruce have usecases
but I'm not sure they're typical and in those small number of cases I'm
sure we can come up with some generic testing/dev repos to assist too.
As soon as something grows to the point where the branch is problematic,
it deserves its own repo and it should be properly namespaced, not user
specific anyway.

I don't understand wanting to keep multiple distinct source trees in a single
git repositorie. If you have two different layers in there, each in its own
branch, then you can only work with one of them at a time. The end-user then has
to have multiple clones of the same repository in order to work with their two
layers. And they will end up naming them something like:

yocto-contrib-layer-1.git
yocto-contrib-layer-2.git

And keep them checked out to the appropriate set of branches... that seems like
a lot of pain to impose on users to avoid setting up personal git repositories.
Personally, I think I would revert to my kernel.org repositories rather than try
and make this work.

Or - is my git-fu weak? Is there a better way to handle the above?

the other seemed clunky.

Maybe I'm misunderstanding as well, but sparse fetch or not (and

I think there are three elements to this:

a) People do like the logical separation that a repo gives them and
find it easiest to think in those terms.
b) Most people are used to single relatively monolithic repos such as
the kernel. People like myself who have used svn with multiple
projects contained within like matchbox or the OpenedHand "misc" svn
repo or the BSD projects approach to source control are probably in
the minority.
c) The git tooling and all the examples out there are geared up to
single repos. git is very much a tool where you need to think as its
authors do.

Agreed.


Some of this can be addressed with clear example documentation about how
to use git in this way.

Partly, these proposals are also working within the constraints of the
git server solution we have too. Are we really in such a bad position
that we need to change all the server setup over this or are there ways
we can work within the existing system (or even extend gitolite)?

I don't know what gitolite is capable of. I would really like to be able
to create and destroy my own repositories in a central location with
other Yocto developers.

However, this doesn't block me from moving forward. I can use kernel.org
or dvhart.com to do this for the time being and make requests of the
admins when I have a repository that looks to have some staying power.
I'll have to time this transition appropriately so that I don't have to
ask too many people to migrate to the new URL, but that would be true of
a personal repository to official repository move as well.

Agreed with the points above. git really is just wrangling a bunch
of objects into commit chains and a branch points to a starting
point. So I completely agree that all chains don't have to lead to
the same origin, like you said, it is just how people tend to think.

I think we are likely ok, people have solutions that work, getting
the right contrib repos setup with appropriate permissions to setup
branches will go a long way.

As long as things stay responsive, I'd imagine that we'll find
that people will be happy with things as they are. At least we've
considered the options before it is critical.

Hi,

Can someone please tell me what needs to be done to build
qemu-system-mipsel or provide a patch for it?

openembedded seems to be able to build something like this, so maybe it
would not be too difficult to cook some of the files from oe for yocto-poky.

Please advise,

Use Case: Tomz has a branch of meta-intel that he has pushed to
poky-contrib.git:tomz/foo. dvhart wants to look at it from his local repo:
I'm curious how many people reading this feel this is "basic git". Anyone
willing to admit this was the first time they have seen a targeted branch
fetch used to avoid a larger download? If everyone is comfortable with this,
fine. If not, we should consider the impact of this type of access on our
users.

git remote add poky-contrib ssh://git@.../poky-contrib.git
git fetch poky-contrib tomz/foo:foo
git checkout foo
My biggest complaint with this is the lack of self discovery from within git
without doing a git remote update. Unless tomz is online at the time to tell me
it's tomz/foo-bar, not tomz/foo_bar, then I have to go load the web browser and
check which branches are available, or resort to downloading all the objects.


I confess though, it still just feels wrong to keep unrelated source trees in
the same repository.


The fetch allows a sparse checkout of *just* tomz's branch. No need to
download all 75M of poky-contrib which is what you would do with "git remote
update". Git remote update is the wrong way to do this and I'd like to avoid
having to swap infrastructure around when it seems to me that this is just
one of those "git being a pain to learn"
Just to add to this discussion, with gitolite, it should be easy to
setup a yocto-contrib repo where each user "owns" the branches under
<keyname>/*. This means as ssh keys are added, they'd automatically get
their own "scratch" area. As Beth points out above, its perfectly
possible to checkout branches and manipulate them as long as you know
the commands.

This isn't a set of repos per user but when you think about this, how
often do we really need that? Yes, some people like Bruce have usecases
but I'm not sure they're typical and in those small number of cases I'm
sure we can come up with some generic testing/dev repos to assist too.
As soon as something grows to the point where the branch is problematic,
it deserves its own repo and it should be properly namespaced, not user
specific anyway.

I don't understand wanting to keep multiple distinct source trees in a single
git repositorie. If you have two different layers in there, each in its own
branch, then you can only work with one of them at a time. The end-user then has
to have multiple clones of the same repository in order to work with their two
layers. And they will end up naming them something like:

yocto-contrib-layer-1.git
yocto-contrib-layer-2.git
This is what I was wondering as well. I had my meta-kernel-dev as
a branch on poky-extras and ran into exactly this problem. Either
have two clones, or get it into master. Master was the choice, since
the other seemed clunky.

Maybe I'm misunderstanding as well, but sparse fetch or not (and
yes I've done/used it), logically I like things that are distinct
source trees to be separate repos. Maybe it's a kernel-guy thing ? :)

Cheers,

Bruce


And keep them checked out to the appropriate set of branches... that seems like
a lot of pain to impose on users to avoid setting up personal git repositories.
Personally, I think I would revert to my kernel.org repositories rather than try
and make this work.

Or - is my git-fu weak? Is there a better way to handle the above?

I don't agree. I have a few sparse layers and some other code that I am

Different use case from what I'm seeing as the general concern, however, I would say that if someone has code that doesn't belong in oe-core but it's standalone and useful to the project, then you would put in a request to have a new repo added. And maybe that's a good argument for new infrastructure if the current process doesn't scale well (which I don't have data that would come to any conclusion like that).

Having said that some of these recipes may be useful to others yet
definitely don't belong in oe-core. What do I do with them? The
mechanism Darren describes seems like it would work for my use case.
Ask me to create a repo. If I was getting a flood of repo creation requests or there was a use case that was compelling, I'd be on board with this in a heartbeat, but to me, it just seems like it's better served by people understanding the process better.

The current process is to send me an email (ccing RP), saying what repo you want, why you need it and then we go from there and create it, if it makes sense. I think I'm specifically worried less about your use case (I get *maybe* a repo request a month) than I am about people justifying an infrastructure change in order to have a whole bunch of contrib repos. That is better served by sparse fetches of needed branches from poky-contrib.

git.yoctoproject.org hosts a number of different repositories, some of
which host limited user contributions (such as poky-contrib). These
repositories are setup and administered by a yoctoproject.org system admin.

As our developer base grows, the need for user creatable git trees also
grows. Eventually, *-contrib isn't going to scale, and neither will the
system admin. There are plenty of available places individuals can
create publicly accessible trees (github, kernel.org, or any number of
similar sites). However, I think it would be beneficial for at least
very active developers to be able to create and destroy trees on a whim,
without having to involve the system admin with each event.

kernel.org provides a git web interface for user created trees. I'd like
to see something similar available at yoctoproject.org in order to
establish single place to go looking for "yocto developer trees". Users
would have to justify their request for a user account and agree to a
terms of use. This has served the Linux kernel community very well. I
think it could do the same for us.

Note: I am not offering to setup such a service or even say that it's
possible with the current resources. I just wanted to throw the idea out
there and see if others have found a similar gap in the development
environment and if this idea would address that gap.

Have you though about setting up a gitorious instance on git.yocto?
I think that is a fantastic idea, it gets my vote.
