git whitespace woes

Question

Whitespace, it turns out, has ended up being a horrible pain for me while using git.

git config apply.whitespace=strip seems to highten your chances of getting conflicts (as you strip unneeded whitespace and then other collaborators see the stripped whitespace as a change to their commits?)

I've tried a few other configurations for apply.whitespace in the past, and maybe one of the other configs solves this, or maybe there's other settings to deal with whitespace that I just haven't come across, but I haven't yet found a clear way to get where I want to be.

Where I want to be: I never want to have another conflict on whitespace. If another committer alters whitespace, or I alter whitespace and then have to merge against my own conflicts, i really don't want to know about it. If someone changes my code from K&R style to One True Brace style by changing whitespace, I'd prefer git paying no attention over having to see conflicts about it.

So... ...is there any way that I can configure git to do that?

If it makes any difference, here's my git version, and my current config:

tchalvak:~/ninjawars$ git --version
git version 1.6.0.4

tchalvak:~/ninjawars$
git config --list
color.branch=auto
color.diff=auto
color.status=auto
color.branch.current=yellow reverse
color.branch.local=yellow
color.branch.remote=green
color.diff.meta=yellow bold
color.diff.frag=magenta bold
color.diff.old=red bold
color.diff.new=green bold

Answer 1

The real problem here is that you are working with people who can't agree on a coding style.

Answer 2

Git1.6.0.4 seems a bit old, especially if you consider that:

• in 1.6.3.4, "git apply --whitespace=fix" did not fix trailing whitespace on an incomplete line
• in 1.6.3.2, "whitespace" attribute that is set was meant to detect all errors known to git, but it told git to ignore trailing carriage-returns.

Could you try with Git1.6.4.1, and rather than setting a global config, set an attribute on the files you want a special whitespace handle, like this article describes.

In a given directory, create a .gitattributes file.

* -whitespace

which will ignore any 'whitespace' errors.

Now that will not prevent any conflict due to lack of consistency but that may be worth trying.
