submodule problem

submodule problem

[John Dlugosz]

I thought I knew what I was doing, after reading the instructions.



When I checked out an older version of the main project, I have to sync to the proper (older) version of the submodule too.  git admonished me to run the command from the toplevel of the working tree, and when that was done,



        git submodule update



gives no output.



        git submodule status



shows "-8441e..." which is the SHA1 of the version I expect I need.  But git status shows me that the submodule is modified.  git gui shows



        @ -1 +1 @@

        -Subproject commit 8441ea2e54fa2e8a4f45240a0d399f1c775a1789

        +Subproject commit bc47be2d623cbca83701d9f30a18fab6271dd38f



and gitk, run from the subproject's subdirectory, shows that bc47b, the newer stuff, is still active.  Browsing the files, I see this is indeed the case.



Now, my impression was that 'git submodule update' was supposed to check out the proper version, namely 4441e, not merely do nothing without even an error.  What am I missing?

Did you run 'git submodule init'?  You generally have to do this once per repo.

The '-' prefix indicates that the submodule isn't registered in your
.git/config. You should have a 'submodule.$name.url' entry in the
config (where $name is the name of the submodule as found in
.gitmodule').

Thanks.  The slashes were going the wrong way, e.g.

	[submodule "Source\\Shared\\Aardvark"]
		url = //tx01fs01/SYS/dev/git/repositories/Aardvark.git

It did not work at all when I first created it with "submodule add", and manually fixed the .modules file.  I need to do the same with the entry in .git/config.

I did give the Unix-style slashes when I called submodule add.  It must have code somewhere that gets a listing or something from an OS primitive and didn't reverse it.  A bug in msys, or some code that bypasses the abstraction layer, or something in a Perl program, perhaps.
