[PATCH v4 19/19] future: pull: enable ff-only mode by default

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The user has been warned that this change was coming and should have
already configured his/her preference.

It's time to flip the switch and make ff-only the default.

There's no need for the annoying warning anymore.

TODO: Do we want to keep the "pull.mode=ff-only" tests and essentially run
them twice?

-By default `git pull` will warn about these situations, however, most likely
-you would want to force a merge, which you can do with `git pull --merge`.
+By default `git pull` will fail on these situations, you will have to
+specify whether you want `--merge` or `--rebase`.
 
 Then "`git pull`" will fetch and replay the changes from the remote
 `master` branch since it diverged from the local `master` (i.e., `E`)
