Yes it helps but I still wonder whether thereis a "simpler" way to
achive that.
Is it possible to split a patch selecting the hunk in git gui or any
other graphical
tool?
You can apply the patch without commiting it, and them make several
partial commits, by right-click "stage hunk for commit" in git-gui.
Yes, and you can do the same with "git add -i". These tools are
not quite nice, as they encourage a wrong workflow of committing
what you haven't had as a whole in the work tree. By
definition, you are making untested commits between your base
commit (that presumably was tested well) and your final commit
(that would also be tested well).
And as another alternative, seeing as Git is so easy to script, it is
trivial to make a script that checks out all the commits in a series
and runs the test suite against them. This of course assumes that you
have a test suite!
For example, this is the script that I use on a topic branch before
submitting the corresponding patch series. It's one of the first
scripts for Git that I wrote, so it is probably a bit naïve, but it
works in the basic case. Basically bails if "make clean && make test"
doesn't work for any commit in the series.
I've used this on the series that I've sent to the Git mailing list,
but you can use it internally on your local projects too before
merging topic branches.
