With git/github I really only pull and push. I don’t really use any of the other features. Same for the kids on my robotics team. The only thing I have taught them is pull and push. The kids do a pull at the beginning of practice and a push at the end. Yet sometimes I see this in the commit logs. Why are these merges happening? Even I have some merges and I know I didn’t do anything differently. Should I be concerned? We are doing all of our git/gihub work in VS code if that matters.
To expand on this a bit,
git pullunder the hood is basically a shortcut forgit fetch(get the remote repository’s state) andgit merge origin/main main(merge to remote changes to your local branch, which for you is always main).When you have no local changes, this process just “makes a line” in your commit history (see
git log --graph --decorate), but when you have local changes and the remote has changed too, it has to put those together into a merge commit - think a diamond shape with the common ancestor at the bottom, the remote changes on one side, your changes on the other side, and the merge of the two at the top.Like the above comment says, normally this process is clarified at the command line - VSCode must be handling it automatically if there are no code conflicts.
