Re: [ros-dev] Modularizing the ReactOS repo in Git

[Alexander Sh.]

Since we have RosBE, we can have multiple repositories without actually
binding them and download them on demand. Or we can make a build script for
every new small module that downloads (clones) repos it needs.

Hi all!

After David has successfully tested a first SVN -> Git conversion of our
repo, here comes the next challenge: Finding a way to preserve our current
modularization into reactos, rosapps, rostests and paving the way for even
more modularization.
My vision for the future is a small "core" repo that only contains our host
tools and SDK. We could also split off subprojects like fast486/ntvdm or
Paint into individual repos. Now that Microsoft has abandoned them under
Windows, they may individually attract developers who would never hack on
the entire ReactOS repo. Furthermore, 3rd party components could be
imported through their repo instead of copy-pasting their code without
history (as we do now).
Even if that vision is a distant goal, the technology for it is already
required for a reactos, rosapps, rostests modularization.

Isn't that a perfect scenario for Git submodules?
Not sure: I'm not aware that they support the concept of optional modules.
You could only check out the "core" repo with all defined submodules. This
would make it impossible to use "core" only to build Paint. There also seem
to be other drawbacks when using submodules: https://codingkilledthecat.wor

Alternatives like Git subtrees, Google Repo, and Gitslave exist, but there
is even less information about them. Furthermore, I think a good
integration into GUI tools like TortoiseGit is also a requirement for most
of us.

David and I have started to write down our findings:

Your input on this is very welcome!

I guess any migration to Git is blocked before we have a solution here.


Cheers,

Colin
