Advanced Merging in GIT
Merging in Git is typically fairly easy. Since Git
makes it easy to merge another branch multiple
times, it means that you can have a very long lived
branch but you can keep it up to date as you go,
solving small conflicts often, rather than being
surprised by one enormous conflict at the end of
the series.
However, sometimes tricky conflicts do occur.
Unlike some other version control systems, Git
does not try to be overly clever about merge
conflict resolution. Git’s philosophy is to be smart
about determining when a merge resolution is
unambiguous, but if there is a conflict, it does
not try to be clever about automatically resolving
it. Therefore, if you wait too long to merge two
branches that diverge quickly, you can run into
some issues.
