irmin

Also a git implementation in pure OCaml, used for irmin git-based kv storage: https://github.com/mirage/ocaml-git https://github.com/mirage/irmin

Is this similar to Irmin (https://github.com/mirage/irmin) ?

Very cool. I would love to have something like this production ready. Some day... Anyone who finds this interesting may also be intrigued by Irmin [0] - a library for applications to persist data in a git-compatible format. [0] - https://github.com/mirage/irmin

I once wrote super simple `git in js` for data objects. Was less than a couple of hundred of lines. But there's also - https://github.com/mirage/irmin

So why can't they use something like Irmin? https://github.com/mirage/irmin

The Github repo[1] says "This repository is currently offline". I've never seen this message on github before, I'm not really sure what it means. Github then refers me to the "working when Github goes down" article, but Github hasn't really gone down.. I can access every other repo I try to access. Just not this one.

There was some discussion about Irmin just over a year ago [1] and it's been steadily improving ever since. The Readme on the repo [2] lists the bleeding-edge users too, so you can see examples of how it's been applied -- (note to self: we should probably write an update about the progress to date).

interesting to see this! the first thing that came to mind was irmin, from the good folks at MirageOS. unikernels provide an interesting opportunity to rethink block storage, as you're no longer bound the rest of your operating system. curious to see how gitfs and irmin develop. https://github.com/mirage/irmin

https://github.com/mirage/irmin might be a candidate?

How does this compare to Irmin[0][1][2], a similar system written by the guys working on Mirage? On first glance the one major difference I see is that Irmin supports merges, while Pfs does not. Also, what exactly is specific to Docker here? [0]: https://github.com/mirage/irmin [1]: http://openmirage.org/blog/introducing-irmin [2]: http://openmirage.org/blog/introducing-irmin-in-xenstore

That's a reasonable way to think about it, except that Git is just one backend option in Irmin, whereas git-annex is obviously specialized for git (and does it very well, too). The Irmin in-memory store, for example, never actually serializes into Git (and so is faster for IPC). There are some interesting tricks going on from the native Irmin representation to the Git conversion (which is slightly less descriptive than Irmin and so virtual nodes are constructed to represent the extra data in Git). Will write that up in more detail in a future post I think, but for now: https://github.com/mirage/irmin/blob/master/lib/backend/irmi... https://github.com/mirage/irmin/blob/master/lib/backend/irmi... (is the Git serializer, and you can see in the interface how you can spawn an on-disk and in-memory Git). and the simpler in-memory backend: htt

This blog post just introduces the overall architecture and pointers to the source code. There's a getting started guide for those who want to play with it here: https://github.com/mirage/irmin/wiki/Getting-Started More docs emerging in the coming weeks (particularly as we upstream the Xen toolchain integration, which has been a very helpful deployment to iron out the bugs in the betas). Do feel free to file questions on <https://github.com/mirage/irmin/issues> in the meanwhile.
