Relative URL for Git submodule

I think that I should have use relative URL for Git submodule. Here, I explain why, and how I do.

Background

In Gnuk git repository, it uses Chopstx as submodule. In NeuG git repository, it uses Chopstx and Fraucheky as submodule.

Git repositories of Gnuk and NeuG are available at different sites (gniibe.org and Gitorious.org). It can be accessed by SSH or Git protocol, as registered user or anonymous user.

I was careless when I registered submodule under main project, and I wrongly included my username in its 'url', which will be incompatible for anonymous user.

I was also careless when I registered Chopstx at Gitorious.org. While Gnuk git repository is gnuk/gnuk, Chopstx git repository is chopstx/chopstx.

Problems

When anonymous user cloned Gnuk repository, he needed to change url of submodule manually.

When I cloned Gnuk repository from gniibe.org, I accessed Gitorious.org for Chopstx, even though access to gniibe.org would be more natural.

Tidy it up

In May 2014, I moved www.gniibe.org to different machine. As this was good opportunity, I also changed roles and layouts of gniibe.org on this move.

I no longer serve git repositories from www.gniibe.org, but it is from git.gniibe.org (names are different, although it is actually same host).

When it was served from www.gniibe.org, I didn't have subdirectories like gnuk/ or chopstx/. This time, I moved gnuk to gnuk/gnuk, and I created chopstx/chopstx at git.gniibe.org, so that path layout will be as same as Gitorious.org.

Relative URL

I changed gnuk/.gitmodules to:

[submodule "chopstx"]
    path = chopstx
    url = ../../chopstx/chopstx.git

And neug/.gitmodules to:

[submodule "chopstx"]
    path = chopstx
    url = ../../chopstx/chopstx.git
[submodule "fraucheky"]
    path = fraucheky
    url = ../../chopstx/fraucheky.git

Now, anonymous user access of chopstx repository under gnuk will be anonymous user access.

SSH access of chopstx repository under gnuk to git.gniibe.org will be SSH access of git.gniibe.org.

Fine.
