Git can +expose each namespace as an independent repository to pull from and push +to, while sharing the object store, and exposing all the refs to +operations such as linkgit:git-gc[1]. + +Storing multiple repositories as namespaces of a single repository +avoids storing duplicate copies of the same objects, such as when +storing multiple branches of the same source. The alternates mechanism +provides similar support for avoiding duplicates, but alternates do not +prevent duplication between new objects added to the repositories +without ongoing maintenance, while namespaces do. + +To specify a namespace, set the `GIT_NAMESPACE` environment variable to +the namespace. For each ref namespace, git stores the corresponding +refs in a directory under `refs/namespaces/`. For example, +`GIT_NAMESPACE=foo` will store refs under `refs/namespaces/foo/`. You +can also specify namespaces via the `--namespace` option to +linkgit:git[1]. + +Note that namespaces which include a `/` will expand to a hierarchy of +namespaces; for example, `GIT_NAMESPACE=foo/bar` will store refs under +`refs/namespaces/foo/refs/namespaces/bar/`. This makes paths in +`GIT_NAMESPACE` behave hierarchically, so that cloning with +`GIT_NAMESPACE=foo/bar` produces the same result as cloning with +`GIT_NAMESPACE=foo` and cloning from that repo with `GIT_NAMESPACE=bar`. It +also avoids ambiguity with strange namespace paths such as `foo/refs/heads/`, +which could otherwise generate directory/file conflicts within the `refs` +directory. + +linkgit:git-upload-pack[1] and linkgit:git-receive-pack[1] rewrite the +names of refs as specified by `GIT_NAMESPACE`. git-upload-pack and +git-receive-pack will ignore all references outside the specified +namespace. + +The smart HTTP server, linkgit:git-http-backend[1], will pass +GIT_NAMESPACE through to the backend programs; see +linkgit:git-http-backend[1] for sample configuration to expose +repository namespaces as repositories. + +For a simple local test, you can use linkgit:git-remote-ext[1]: + +---------- +git clone ext::'git --namespace=foo %s /tmp/prefixed.git' +---------- + +SECURITY +-------- + +Anyone with access to any namespace within a repository can potentially +access objects from any other namespace stored in the same repository. +You can't directly say "give me object ABCD" if you don't have a ref to +it, but you can do some other sneaky things like: + +. Claiming to push ABCD, at which point the server will optimize out the + need for you to actually send it. Now you have a ref to ABCD and can + fetch it (claiming not to have it, of course). + +. Requesting other refs, claiming that you have ABCD, at which point the + server may generate deltas against ABCD. + +None of this causes a problem if you only host public repositories, or +if everyone who may read one namespace may also read everything in every +other namespace (for instance, if everyone in an organization has read +permission to every repository). diff --git a/builtin/receive-pack.c b/builtin/receive-pack.c index 0d51bfb79e..60260d0aa9 100644 --- a/builtin/receive-pack.c +++ b/builtin/receive-pack.c @@ -120,9 +120,25 @@ static int show_ref(const char *path, const unsigned char *sha1, int flag, void return 0; } +static int show_ref_cb(const char *path, const unsigned char *sha1, int flag, void *cb_data) +{ + path = strip_namespace(path); + /* + * Advertise refs outside our current namespace as ".have" + * refs, so that the client can use them to minimize data + * transfer but will otherwise ignore them.
