Multiple Repository support

Multiple Repository support

[Cliff Brake]

Hello,

I've started collecting ideas from various emails on multiple
repository support.

http://wiki.openembedded.org/index.php/MultipleRepositoryMethods

Please feel free to update the above page.

In my mind, this is a key problem we need to solve, not just for
Yocto/OE, but also for anyone doing product development.

I've personally been using git submodules for most projects, and repo
for Android based projects.

Appreciate any ideas, experiences, or insights into how we solve this problem.

Thanks,
Cliff

We are using git submodules for just this task in OE-lite.
It works pretty well, but I fear that this will not be the case if a
push model is used for the top repository.

We have partly wrapped the git submodule configuration into a bitbake
parsed configuration file, looking something like:

# OE-lite/core metadata
OE_MODULES                      += "core"
OE_MODULE_PATH_core              = "meta/core"
OE_MODULE_URL_core               =
"git://git.doredevelopment.dk/oe-lite/core.git"
OE_MODULE_PUSHURL_core           =
"ssh://dev.doredevelopment.dk/srv/public/git/oe-lite/core.git"
OE_MODULE_BRANCH_core            = "master"
OE_MODULE_REMOTES_core          += "gitorious"
OE_MODULE_REMOTE_core_gitorious  = "git@gitorious.org:oe-lite/core.git"

So developers get a more complete and consistent submodule setup.

We considered repo, but the KISS principle ruled in favor of git
submodules.  I believe the learning curve is steep enough for any
newcomers to OE, so having to figure out how to master something like
repo also does not seem so attractive.

I seem to have no account and only administrators may create one.

From the list mentioned in that page I only used git submodules so far. 
Handling could be simpler, that's right.  On the other hand there was work 
done in git regarding submodules, see

http://git.kernel.org/?p=git/git.git;a=commit;h=4bb4d30095fbc3b1689cc656e71f6a51e43fbd69

16-dec-2010.  So perhaps some of the bad things will be easier in the next 
release.
