Convert path separators in patch file to unix explicitly #35

wants to merge 2 commits into from

@JornVernee JornVernee commented Aug 1, 2019

I ran into trouble when trying to apply a patch file generated with Windows Git to a mercurial repository through cygwin. It wasn't recognizing the files since the paths in the patch file were using Windows path separators.

The spec doesn't seem to mention path separators:

But, both the Windows Git and Mercurial clients I have installed are handling unix path separators just fine. So, in this PR I've changed the patch file generators to use unix path separators explicitly, which solves the problem.

Hi Jorn,

thanks for testing out the tools using Cygwin!

The patch itself looks good, but maybe this patch should take the opportunity to fix as well? I would prefer moving away from Webrev having its own logic for creating .patch files, it should use Diff::write and Diff::toString instead. I suspect we have the same exact issue in Diff::write, so please fix the bug there as well, even if you don't refactor Webrev to use Diff::write 🙇‍♂️

I've just fixed the problem for Patch::write as well, since switching Webrev to use Diff::write is not a simple switch. The latter does not have support for printing hunk context lines it seems. Doesn't seem like a quick fix, and I don't really have time to look into it right now :/

I ran the vcs module tests, but this is the one that had a lot of failures (27). I can say that at least there were no additional failures from the Patch::write change, but you might want to test on your side as well.

Sorry for taking so long to review this @JornVernee, the patch looks good! I executed sh gradlew test on Linux x86_64 and all tests passed!
