How to preserve merge commits automatically while using git pull --rebase?

I want to keep the branch information of merged branches, so I have set up branch.master.mergeoptions=--no-ff. This way, a merge commit is always generated even when it could be fast-forwarded.

A side effect however, is that a merge commit is created when doing a git pull (more specifically: Update in IntelliJ or Eclipse). To prevent a log full of Merge remote-tracking branch 'origin/master', I also set branch.master.rebase=true which will fast-forward the master to origin/master when pulling it.

This setup has another side effect: when I merge a branch to master and after that I git pull because I forgot to do that before the merge, my branch information is lost: the feature branch is flattened in master.

The command git pull --rebase=preserve is exactly what I need: it will rebase master, then apply the merge of the branch again. But I need this to be done automatically, since most of these commands are executed by Eclipse or Intellij. I want git pull actually perform a git pull --rebase=preserve

There's a config setting pull.rebase=preserve which should do just that, but even after I set this config, git pull will do just a git pull --rebase and not the expected git pull --rebase=preserve, while I'm currently using git version 2.12.2 which is expected to contain that feature.

So how can I make sure that when I do a git pull on my master, that it will preserve my merge commits even when I didn't update my master before the merge?

The setting branch.master.rebase=true is actually overriding the default pull.rebase=preserve.

The solution is to execute the command git config branch.master.rebase merges so that the config setting is now branch.master.rebase=merges. This will preserve the merge commits automatically when doing a git pull
