![]() ![]() The main point is to recognize where the changes are coming from, main/master or the new_feature. We’ll still see the difference between the two. ![]() This doesn’t mean they don’t differ though, since we can obviously see from the graph there is a new commit (newly implemented feature) in our “new_feature” branch, so if we execute something like: In other words (git terminology), this happens when the branch we’re trying to merge is a parent of our currently checked out branch (meaning our current branch was based off of the branch we’re trying to merge). Thinking in mathematical terms, we can simply say that main/master is a subset of a new_feature, meaning it already contains all its commits so there’s nothing left to “bring” to our branch that’s not already there. So, if you try to issue “git merge main” (or “git merge master”, if your main branch is called master), the message “Already up-to-date” will be shown, indicating there is nothing to “bring” from main/master to new_feature branch, that feature branch doesn’t already have. What we can tell from that graph is that our “new_feature” branch was created from our main/master branch, which means it contains all there is on the main/master branch, and some new_feature code that was built upon that (which is not present on the main/master, meaning they differ). The following “graph” represents the commit history on our main/master branch and let’s say our development branch, which we can call “new_feature” branch in this example. Ok, let’s consider the repository with the following commit history: So let’s dive deeper into why this happens and explain/clarify what is the solution in those situations by considering two different scenarios □ This issue appears when you try to do something that doesn’t need to be done, most often caused by misunderstanding of how git actually works. Well, from what I managed to gather, the answer is quite simple. The following is an example of git branch output with some demo branch names.To be quite frank, I wasn’t even aware this issue existed until I started writing this article, so it made me wonder how is it possible I never encountered it before, given I have used git for almost 10 years at this point. Executing the git branch command will output a list of the local branch refs. The refs for local branches are stored in the. Git keeps remote and local branch commits distinctly separate through the use of branch refs. git/objects directory, Git stores all commits, local and remote. To better understand how git fetch works let us discuss how Git organizes and stores commits. If you have pending changes in progress this will cause conflicts and kick-off the merge conflict resolution flow. git pull is the more aggressive alternative it will download the remote content for the active local branch and immediately execute git merge to create a merge commit for the new remote content. It will download the remote content but not update your local repo's working state, leaving your current work intact. You can consider git fetch the 'safe' version of the two commands. When downloading content from a remote repo, git pull and git fetch commands are available to accomplish the task. This makes fetching a safe way to review commits before integrating them with your local repository. Fetched content has to be explicitly checked out using the git checkout command. Git isolates fetched content from existing local content it has absolutely no effect on your local development work. It’s similar to svn update in that it lets you see how the central history has progressed, but it doesn’t force you to actually merge the changes into your repository. Fetching is what you do when you want to see what everybody else has been working on. The git fetch command downloads commits, files, and refs from a remote repository into your local repo. ![]()
