47 | * Processing a gitlink entry currently does nothing, since | |
48 | * we do not recurse into the subproject. | |
49 | * | |
50 | * We *could* eventually add a flag that actually does that, | |
51 | * which would involve: | |
52 | * - is the subproject actually checked out? | |
53 | * - if so, see if the subproject has already been added | |
54 | * to the alternates list, and add it if not. | |
55 | * - process the commit (or tag) the gitlink points to | |
56 | * recursively. | |
57 | * | |
58 | * However, it's unclear whether there is really ever any | |
59 | * reason to see superprojects and subprojects as such a | |
60 | * "unified" object pool (potentially resulting in a totally | |
61 | * humongous pack - avoiding which was the whole point of | |
62 | * having gitlinks in the first place!). | |
63 | * | |
64 | * So for now, there is just a note that we *could* follow | |
65 | * the link, and how to do it. Whether it necessarily makes | |
66 | * any sense what-so-ever to ever do that is another issue. | |
