I am trying to generate a diff patch on my local dev box. I want to upload this patch to a server (running Windows Server 2008) and apply it to my staging code. The catch is: I cannot install git on the server to accept the patch. Therefore, I would like to use a generic patching tool (such as patch from the GnuWin32 tools). I tried generating a unified diff with the following command:

git diff -U > diff.patch

and then tried to apply it using:

patch -u -i ..\other_dir\diff.patch

and I got the error:

"patch unexpectedly ends in middle of line" ... "Only garbage was found in the patch input"

It might be a problem with how I'm using patch, and if so, forgive me. If not, then how can I generate a generic diff format from git so I can do what I want?

Thanks all! Joe Fiorini

Just a guess, but the gnuwin32 tools might not like unix line endings. Try opening and re-saving in wordpad (or vim :set ff=dos, or $insert your favorite method here).

Re: Apply patch on server w/o git

I just tried it and no luck.  Anyone have any other ideas?

That won't actually work! The problem is, that:
 - The headers (+++/---/@@ lines) should have dos line endings (but does not
   matter too much).
 - The bodies must have the same line endings the actual code does.

Question is, what the code has (it could have been transfered by some method that converted the line-endings or something).

Also trying to patch with ignoring whitespace could work (I believe I did that the other way 'round -- applying windowsy newline-damaged patch on unix). And if it does not, it's not the newlines problem.

You can try git-apply instead of patch. It is a bit smarter (and not outsmarting itself either).

Re: Apply patch on server w/o git

Thanks for all your replies. Unfortunately, I cannot use git apply because I will not have access to git on the server where I'm doing the patch. I will try Jan's suggestion of ignoring whitespace.

By the way, why *can't* you use git there? There is win32 build of git (http://code.google.com/p/msysgit/) and if you can't get the repository over (but if you can get anything there, you should be able to get bundles there too), you can still use git-apply, since it can work without a repository as a pure patch replacement.
