submodules : switching to an older commit/Tag in project with submodules

submodules : switching to an older commit/Tag in project with submodules

[Shani Fridman]

Hi everybody,

I've got a question regarding submodules -

I'm working on a git project with submodules connected to it, and pulling changes from them every month (more or less).
Sometimes I need to checkout older versions of the project (tags or specific commits), that needs the older versions of the submodules as they were when I defined the tag. The problem is, that the checkout only changes the superProject directories, and not the submodules... I have to checkout the relevant submodules commit manually.

Have you came across the same problem? Any idea what can I do?

Thank you in advance,

Shani

git checkout learned about the --recurse-submodules flag some time
ago. If that is what you need, just set 'git config submodule.recurse
true' so you don't have to pass that flag every time.

Hope that helps,
Stefan

You run "git submodule update".

The problem is, some people consider that I have to do things
"manually" X-<.

I may be wrong, but I read that part as e.g. cd-ing into each submodule
dir, and checking out the commit you see in "git diff" from the
top-level, hence the suggestion.
