with structuredAttrs lists will be bash arrays which cannot be exported
which will be a issue with some patches and some wrappers like cc-wrapper
this makes it clearer that NIX_CFLAGS_COMPILE must be a string as lists
in env cause a eval failure
checkInputs used to be added to nativeBuildInputs. Now we have
nativeCheckInputs to do that instead. Doing this treewide change allows
to keep hashes identical to before the introduction of
nativeCheckInputs.
See https://github.com/hedning/nix-bash-completions/issues/20.
Even with the low priority on this package, completing `nix-build` will
load the nix-bash-completion for the `nix` command, which is undesirable
since Nix provides its own completion since 2.4.
The maintainer seems unresponsive.
If bash is executed within an environment where PATH is not set, it uses
the DEFAULT_PATH_VALUE compiled into bash to set PATH. In nixpkgs we set
this to /no-such-path by default. This makes sense in a nixpkgs/NixOS
environment since paths like /bin or /usr/bin should not be used.
However, when bash is used inside an FHS environment, this produces
results that differ from distributions which follow the FHS standard.
Before this change:
$ steam-run env -i /bin/bash -c 'echo $PATH'
/no-such-path
After this change:
$ steam-run env -i /bin/bash -c 'echo $PATH'
/usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:.
- make the script runnable from any directory
- add missing nix dependency to run nix-hash
- make padding non implicit
- small shellcheck fixes (variable quoting...)
Readline 8.1 is required for bash-5.1 to work properly.
From bash-5.1 release message[1]:
> Bash can be linked against an already-installed Readline library
> rather than the private version in lib/readline if desired. Only
> readline-8.1 and later versions are able to provide all of the symbols
> that bash-5.1 requires; earlier versions of the Readline library will
> not work correctly.
