Hi,
I am starting to learn submodules and hit the first state of
confusion when I encountered git-submodule init:
After git-submodule add, I find in my repository a .gitmodules file
as well as the newly-cloned submodule. I can call git-submodule
status on it to get the HEAD hash. The .gitmodules file has a stanza
for each submodule, linking remote url to local path, e.g.:
[submodule "foo"]
path = foo
url = ../foo.git
The manpage then talks about git-submodule init:
init
Initialize the submodules, i.e. register in .git/config each
submodule name and url found in .gitmodules. The key used in
.git/config is submodule.$name.url. This command does not
alter existing information in .git/config.
When I run git-submodule init, the following stanza gets added to
.git/config:
[submodule "foo"]
url = ../foo.git
Unless I call init, I cannot use git-submodule update.
But looking at the two stanzas, it strikes me that the remote url of
the submodule is duplicated and detached, creating redundant data
which may become desynchronised.
Why is this?
What is the reason for git-submodule init and moving the data to
.git/config?
Thanks,
