    Facebook rewrote Mercurial, while Microsoft has essentially expanded git with their own virtual file system VFSforGit [0] and a bunch of performance improvements.

    BTW : with so many smart and connected people interested in source control management in one place, does anyone know what happened to veracity scm (http://veracity-scm.com)?

    It was very promising but the suddenly stopped updating and then (more or less intentionally it seemed) links stopped working, but the site is still up 7 years later...

    There is more tooling needed in general - just one recursive grep will populate the entire EdenFS.

    I suppose FB has better tools. But I won’t touch this until the ecosystem is sufficient (and also, because git and hg are perfectly sufficient for the monorepo I oversee)

    Interesting. This might be a step in the direction of being able to store big files in repositories without hassle.

    However, perhaps OS level support would be preferred. Imagine you have a type of symbolic link that is not just followed, but executed when you access it. That would be really powerful and would allow this kind of optimization. And you wouldn't even need to install or run anything.

    Does this work together with a build cache? My dream setup for dealing with building huge code bases is a file system integrated with the version control system to only download files when they are accessed (which sounds like what this does) but also employing a build cache and module system, so it doesn't even need to download and compile any module that has not been touched, it just downloads the result from the build cache instead.

    > A virtual filesystem for speeding up the performance of source control checkouts.

    To describe it as a filesystem matches my thinking [0]: "It already resembles a network file system, so it should provide an interface nearly as easy to use."

    If it really takes off as an Open Source project, we might be able to "mount" repostories eventually.

    If I were going to try something other than git, it would be fossil => https://fossil-scm.org/home/doc/trunk/www/index.wiki

    I think the one big differentiator for this is:

    "EdenSCM is not a distributed source control system. In order to support massive repositories, not all repository data is downloaded to the client system when checking out a repository"
