This caused shebangs that were already store paths to be rewritten.
Introduced by ab4c359822 in #94642
Example difference:
$ echo "hello world" | tail -c+3
llo world
$ str="hello world"; echo ${str:3}
lo world
Go beyond the obvious setup hooks now, with a bit of sed, with a skipped case:
- cc-wrapper's `dontlink`, because it already is handled.
Also, in nix files escaping was manually added.

Commit "patchShebangs: Allow for multiple arguments" 4a1e51f957
removed the check. We don't want to break existing usages so this
introduces it again with a successful exit code.
It's tempting to think patchShebangs supports multiple arguments.
Without this patch it just silently ignores all but the first. Now it
patches the shebangs in all of its arguments.
Fixes: #57695
Creating the timestamp in the patched script's directory has a few
drawbacks:
* if "foo.timestamp" already exists, it will be overwritten
* it requires the directory to be writable
Completely breaks darwin. Every package in the stdenv that has shebangs
in the output will end up with references to bootstrap-tools.

Completely breaks darwin. Every package in the stdenv that has shebangs
in the output will end up with references to bootstrap-tools.
This reverts commit eb7c50a993.
In strictDeps=false, autoPatchshebangs should use
--build (corresponding to PATH) to lookup commands. This restores the
previous behavior of patchshebangs so that we don’t break stuff that
isn’t careful in the buildInputs vs. nativeBuildInputs distinction.
Unfortunately this won’t work under cross compilation.
This causes problems for packages built using a bootstrap stdenv,
resulting in references to /bin/sh or even bootstrap-tools. The darwin
stdenv is much stricter about what requisites/references are allowed but
using /bin/sh on linux is also undesirable.
eg. https://hydra.nixos.org/build/81754896
$ nix-build -A xz
$ head -n1 result-bin/bin/xzdiff
#!/nix/store/yvc7kmw98kq547bnqn1afgyxm8mxdwhp-bootstrap-tools/bin/sh
This reverts commit f06942327a.
This hopefully makes patchShebangs respect cross compilation. It
introduces the concept of the HOST_PATH. Nothing is ever executed on
it but instead used as a way to get the proper path using ‘command
-v’. Needs more testing.

Prior to this commit, trailing whitespace would be introduced when
modifying '#!' lines with no arguments. For example (whitespace added):
/nix/store/.../foo: interpreter directive changed
from "/bin/bash"
to "/nix/store/...-bash-4.3-p42/bin/bash "
/nix/store/.../bar: interpreter directive changed
from "/bin/baz wef"
to "/nix/store/...-baz wef "
We add a sed command to strip trailing whitespace, so the above commands
would drop the two spaces after "bash", or the one space after "baz wef".
abbradar: fixed commit title
Closes#16785.
Fixes#9044, close#9667. Thanks to @taku0 for suggesting this solution.
Now we have no modes starting with `/` or `+`.
Rewrite the `-perm` parameters of find:
- completely safe: rewrite `/0100` and `+100` to `-0100`,
- slightly semantics-changing: rewrite `+111` to `-0100`.
I cross-verified the `find` manual pages for Linux, Darwin, FreeBSD.
