I have a recollection that this wasn't a silver bullet on the Windows side but I think that may have been before the patch rewriter was added. Regardless, this is well-worth revising, thanks! Even if we end up having to keep the patch pre-processing, at least there's only one patch program then to be considering... |

This is great, I've had problems with GNU patch on Windows from Cygwin, which lead me to replace this code cd ~/opam-repository \
&& (git cat-file -e $OPAM_HASH || git fetch origin master) \
&& git reset -q --hard $OPAM_HASH \
&& git --no-pager log --no-decorate -n1 --oneline \
&& opam update -uwith cd /home/opam/opam-repository \
&& (git cat-file -e $OPAM_HASH || git fetch origin opam2) \
&& git reset -q --hard $OPAM_HASH \
&& git --no-pager log --no-decorate -n1 --oneline \
&& rsync -ar --update --exclude='.git' ./ /cygdrive/c/opam/.opam/repo/default \
&& ocaml-env exec --64 -- opam update -u |

Fixes #3433
Fixes #3782
Fixes #3639 for good
Helps #3482
While looking at #3639 happening for many macOS users, I realized that
git applybasically ships with its own version of GNU patch which works correctly.The original issue is that macOS is a POSIX-complient OS. However POSIX-complient patch seems to be a nightmare: you can't tell it to delete files. It'll just make it empty instead. There are non-posix options (
-E) that deletes empty files anyway but those have another problem where it can't distinguish between you deleting the file and emptying the file... This issue also appears on BSDs.The solution here is to make git a required dependency. Most users will have it anyway and many features are missing without it so it's not too much of a stretch to make it mandatory.
