Found out this is needed while tracking down nix store references to build platform Bash in a cross compiled output.

Shouldn't this be done in postInstall/preFixup?

Shouldn't this be done in postInstall/preFixup?

As written in the comment above, it has to be done before the shebangs are patched for the build platform, so I think there's no choice but to do it here.

I guess another alternative is to use find or similar to exclude this one from being patched by patchShebangs in patchPhase in the first place

I also just found out about --update

nixpkgs/pkgs/build-support/setup-hooks/patch-shebangs.sh

Line 19 in 4dc836c

# --update : Update shebang paths that are in Nix store

which will update shebangs even if they already point to the store

I don't have a strong preference here but if you strongly prefer the host scripts patching to be done in postFixup with the --update flag, I won't mind.

On a 2nd thought, I wonder why --update wasn't used here:

diff --git i/pkgs/build-support/setup-hooks/patch-shebangs.sh w/pkgs/build-support/setup-hooks/patch-shebangs.sh index 5bd1f5078ad0..e15be2dc8443 100644 --- i/pkgs/build-support/setup-hooks/patch-shebangs.sh +++ w/pkgs/build-support/setup-hooks/patch-shebangs.sh @@ -162,7 +162,7 @@ patchShebangsAuto () { if [[ "$output" != out && "$output" = "$outputDev" ]]; then patchShebangs --build "$prefix" else - patchShebangs --host "$prefix" + patchShebangs --update --host "$prefix" fi fi }

Hmm. That could potentially solve this for all packages, huh?

I think this might be worthy of its own discussion and PR.

We gotta do a staging commit anyway so it wouldn't increase the cost in this case.

cc @tie per ebd4619 . Have you considered using --update unconditionally? Also lirc is suffering from the same issue that could be fixed by the above change. On branch master:

Basically the common problem is that often upstream projects mix scripts for $out and for building in the same directory, and patchShebangs being run during patchPhase is patching the $out intended scripts with build platform Bash.

All good now, thank you!

Since I didn't get any attention on this, and I feel like it will take months for this to get attention, I opened 2 PRs for the packages I encountered:

This seems like it would produce incorrect results when you have e.g. a foo-config for the build platform without split outputs and are specifically doing patchShebangs --build on it?

This seems like it would produce incorrect results when you have e.g. a foo-config for the build platform without split outputs and are specifically doing patchShebangs --build on it?

I think that executables like foo-config, that we actually might rely upon, are generated only after the configure phase, in order to know what $prefix etc. to use. I can imagine a situation where it is an executable shell script during the patch/configure phase, and upstream's build scripts embed in it the correct $prefix or whatever. In that case, there shouldn't be a need for us to patch its shebangs, as we are not running it during build, and it would be simpler to let stdenv patch the shebang of it in the standard fixupPhase.

OTH, the (more likely IMO) situation encountered in curl and lirc, is that the upstream source has a directory with shell scripts that are used both for build and host platforms. In that case, there is no choice but to patch the shebangs with --host --update during postFixup, as done in #493000 and #493004 .

There is a 3rd, (very rare IMO) scenario, which is: Along with other build scripts, upstream puts in the source a foo-config executable file, which also gets substituted for values like $prefix during the build; a Nix packager tells the builder to run patchShebangs during patchPhase to make the other build scripts work, and consequently foo-config ends up in $out/bin with a host shebang instead of a build platform shebang (due to this patch).

If the scenario above actually exists, we can always modify that Nix expression to run patchShebangs --update --build $out/bin/foo-config, or even better to split outputs properly.

If this sounds convincing enough, I can write something a bit more concise in the commit message - if it will help.

Many sources of packages mix scripts meant for build and host platforms in the same folder. Two examples of that are `curl` & `lirc`, installing on the host platform `wcurl` & several other executables respectively. When `patchShebangs` runs during patch phase, it uses the build platform. When it runs automatically upon the outputs in the fixup phase, there's no reason it shouldn't `--update` the shebangs of the scripts patched in the patch phase. The common scenario this addresses is upstream source directories containing shell scripts used for both build and host platforms. In such cases, patching with `--host --update` during `postFixup` is necessary (as done for curl and lirc), since the fixup phase should reconcile any build-platform shebangs applied earlier. A concern was raised about `foo-config`-style scripts intended for the build platform that end up in $out without split outputs. Such cases are considered rare: these scripts are typically generated after the configure phase (and thus not affected by an earlier `patchShebangs` call), or can be handled explicitly via `patchShebangs --update --build $out/bin/foo-config`, or ideally by splitting outputs properly.

I rebased, with a better commit message addressing the concern expressed by @emilazy. I'm still waiting for your reply 🙏 on my stand.
