# git clone --recursive should run git submodule update with flag --remote 2 messages from 2015-11-11 to 2015-11-11. Participants: Stanislav, Stefan Beller.

Repo A is embedded into B by using submodule: git submodule add -b master sub-a So, submodule sub-a is set to track master branch of the repo A. Running git submodule update --remote inside repo B will automatically update and checkout submodule sub-a to the latest master commit (as expected). However, when using git clone --recursive , repo B will be cloned with submodule A checkouted to the commmit which was recorded on git submodule add command, not the master commit. Expected behaviour is to automatically update checkout commit pointed by branch, that was specified by -b flag in the git submodule add invocation. Reason for this behaviour is that line: https://github.com/git/git/blob/master/builtin/clone.c#L99 I guess, it should be changed to include --remote flag. ``` ## Stefan Beller, 2015-11-11 19:48 Subject: Re: git clone --recursive should run git submodule update with flag --remote Message-ID: URL: https://gitlist.dev/e/CAGZ79kbOyXm11uPCXcDJzKxbQzBx6ZOmq0TS8kc52xy-qV_FiQ%40mail.gmail.com In-Reply-To: ``` On Wed, Nov 11, 2015 at 4:46 AM, Stanislav wrote: > Consider two repositories, A and B. > > Repo A is embedded into B by using submodule: > > git submodule add -b master sub-a > > So, submodule sub-a is set to track master branch of the repo A. > > Running git submodule update --remote inside repo B will automatically > update and checkout submodule sub-a to the latest master commit (as expected). > > However, when using git clone --recursive , repo B will be cloned > with submodule A checkouted to the commmit which was recorded on git > submodule add command, not the master commit. > > Expected behaviour is to automatically update checkout commit pointed by > branch, that was specified by -b flag in the git submodule add invocation. To achieve what you want to do, you can first clone B and then do a `git submodule update` using the --remote option yourself. That is cumbersome however, I agree. > > Reason for this behaviour is that line: > > https://github.com/git/git/blob/master/builtin/clone.c#L99 > > I guess, it should be changed to include --remote flag. I guess we could tweak the behavior to include the --remote flag when the branch is recorded in the .gitmodules file. Just wondering what should happen if there are both a sha1 and a branch recorded? > > -- > To unsubscribe from this list: send the line "unsubscribe git" in > the body of a message to majordomo@vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html ```
