Oops, looking back I realized that I remembered it incorrectly: The issue was that the file couldn't get applied because the *patch* had Windows lineendings. Not sure how that happened but anyway I stand corrected.
Indeed, that was the case.
I added the full file variation.c as an attachment. It belongs at source/texk/web2c/luatexdir/luaharfbuzz/src/luaharfbuzz/variation.c
and again your variation.c attached has Windows line endings. Anyway, variation.c from variation.c.patch is ok, it is the same of luaharfbuzz-master . In general Windows line endings are not a problem for me, because I am used to run dos2unix before. The default diff (i.e. without ignoring blanks) is annoying because it says that all the lines differ, and I don't run diff -b because spaces matter in comments . Committed revision 7447. -- luigi
