Second, itвЂ™s not really possible to do atomic commits or pushes across multiple reposДЄnd third, most developers are not interested in becoming version control experts,Д¬an't find anything about subtree there, perhaps it's not even an option. In the end, we dropped that approach, because it created nearly as many problems as it fixed.ДЇor one, we found that we were complicating peopleвЂ™s workflows

The entire Windows codebase is moving to a single Git repo. I don't like the idea of HUGE metarepositories the pulling is going to be messy or risky it's not going to be efficient generally, it's a way to distribute an entire collection of applications and libraries for exploration or running automation rather than everyday contributions.Д¬ould someone comment about this from enterprise perspective Generally, devs don't like metarepositories! Too much source control complexity! But metarepos can model actual infrastructure through source dependencies, and that model can go a long way to explaining your infrastructure patterns. I have dev push and pull into the individual repositories, and the metarepository is largely for automation.

I use a small metarepository on a buildserver to integrate a handful of applications with their deploy code, and it's a bit slow to pull, but once it's there I can do a lot of builds quickly and there's better transparency for failure around the automation as all the code is in the same place. It can also be slow to pull, obviously, and parallel pulling is essential, or working on a propagated box. Regarding repositories with hundreds of subs - there's use cases where it seems to make sense (one company I worked with used a metarepository to integrate multiple chef-repos) but you need to write tooling to handle it effectively and abstract away the risk of corrupting the repository through mishandling. I love it as an infrastructure dev environment, but am still working to understand where it otherwise makes sense. Now, I think that is much better than using submodules and a lot less invasive to my doing enterprise infrastructure development for a consultancy and can speak to scale a bit in the context of DevOps if not dev - I'm preparing a conference talk on 'Metaprogramming in Metarepositories' I've gone to subtrees rather than submodules because of the difficulty for users, but I really liked programming with submodules to expose the service dependencies when I'm programming across repositories. To stay up-to-date with the latest in the official repository. I can still do: git subtree pull -prefix=Vendor/AFNetworking -squash master I would issue a pull request and hope it gets accepted, but a big difference is that the acceptance of my change doesn't keep me from being able to easily stay in sync with the official AFNetworking repo.I'll push my change to my fork, but on a branch to make the pull request more awesome.

To set up being able to push changes to my fork.ДЈ. Git subtree split -prefix=Vendor/AFNetworking/ -branch AFNetworking

I'll fork AFNetworking into my account on Github.

But, I want to be a good open source citizen, so what do I do? Be a good open source citizen Technically, I could stop now if I wanted to since the bug fixed code is in my repository. I make my change and commit it to my project's repository. What do I do differently now that I'm using subtrees?

This is pretty similar so far except the other members of your team won't have to remember to run git submodule update because subtrees actually store the source in your repo. With subtreesДЄdd the project to your repo: git subtree add -prefix=Vendor/AFNetworking -squash master If you've ever done it, you know how painful it is and how finicky submodules can be. If it is accepted, do the whole dance to switch my submodule back to the official AFNetworking repo.Wait to see if the pull request is accepted, but keep my fork up-to-date in the meantime.Submit a pull request to AFNetworking repo.Make my change and commit it to my fork.Go through the pain of changing my project's submodules to point to my new fork.Well, what happens if you find a bug in AFNetworking that you want to fix? With submodules, I'd usually How do you integrate it? With submodulesДЄdd the project to your repo: git submodule add Vendor/AFNetworking Let's say you have an iOS project, and you want to use some external library, like AFNetworking.
