I have a nix derivation that inject some files to a source repo, via
postUnpack. Then I wanted apply a patch to that file I injected (this tweak is necessary for my use case). To create the
.patch file, my approach is to create a branch (branch-A) from the master of the repo I am trying to patch, adding the files I injected (to replicate my derivation). Then after that I checkout again another branch (branch-B) from branch-A, then apply my patch here to the injected file. I get the diff and when I apply it to the derivation, I encounter some errors:
- 1st approach: using
patchesattribute → It builds but does not apply my patch
- 2nd approach: via
patchPhaseand applying the patch manually —> It encountered a
hunkerror, meaning patch is not compatible (maybe it compares itself to the master/original repo and not the patched repo I made from unpackPhase).
It seems that the patchPhase only compare itself to the original repos, even though I made some changes in postUnpack. Can someone explain?
