Merging a branch when I don't want conflicts

How do I merge a branch X into my master and tell git that whenever there
is a conflict, the file on X should prevail?  This is for a scripted
application.

Cheers,
Geoff

I assume you talk about file-level (content) merges.

There is no such tool, and the reason is that what you try to do here does
not make sense *in general*. It must be a very special kind of project
where you can blindly trust one side over the other if there are
conflicts, and that you can additionally trust non-conflicting content merges.

The best you can do is perhaps to pipe conflicting files through

    sed -e '/^<<<<<<</,/^=======/d' -e '/^>>>>>>>/d'

Yes.

The file is data coming out of an interactive program which reads
the entire file, edits and then writes the entire file at which point
this file is correct
and all previous versions are obsolete.  I don't really want a merge
at all, but just
want to replace the file in the master with the version on the branch.

Thanks anyway.

Cheers,
Geoff.

Ah, so finally you say what you mean ;)

You can define a custom merge driver that always returns the content of
the second branch. See 'man gitattributes'.

I think -Xours enhancement that was developed long time ago

    http://thread.gmane.org/gmane.comp.version-control.git/76650/focus=89021

should help Geoff's use case.

Sorry for the confusion. A custom merge driver will work fine ... but I
will also rethink carefully  what I am doing.
