The `helperFunctions` and `stdenvAdapters` both use the `pkgs` attribute as
input, either to inherit some properties, either to use it as argument.
The `pkgs` binding used in both expressions of the `helperFunctions` and
`stdenvAdapters` is no longer the result of the `applyGlobalOverrides`
function, but the argument of the `pkgsFun` function.
The `pkgsFun` functions is called twice under `applyGlobalOverrides`, and in
both cases, the first argument of `pkgsFun` correspond to the result of
`applyGlobalOverrides`.
Thus, this modification will change the bindings, but the evaluation of
`<nixpkgs>`.
A third call the `pkgsFun` exists under `overridePackages` in the set of all
packages. Previously, the `helperFunctions` and `stdenvAdapaters` would use
the functions defined as part of the default `<nixpkgs>` set. With this
modification, the `helperFunctions` and the `stdenvAdapters` are now using
the fix-point of the newly evaluated package set.
This implies that this modification allow the user to use
`overridePackages`, which is already not recommended for performance
reasons, to override the inputs of the `helperFucntions` and
`stdenvAdapaters` too, where this was not possible before.
We were previously getting collissions for the following
2 files with files from the dropbox package:
- bin/dropbox
- share/applications/dropbox.desktop
As a consequence the binary has been renamed to dropbox-cli and
the .desktop removed as it is redundant.
- missing cd command
- invoke bundler through nix-shell, so it doesn't need to be on $PATH
Note: running bundix through nix-shell won't work ATM, as the shell sets
SSL_CERT_FILE=/no-cert-file.crt which prevents fetching throug https.
- use version from gemset to simplify updating
- don't break line in meta.description
Setting the GEM_PATH after ruby is started is not reliable enough. In
some cases rubygems would have already loaded and ignore these settings.
Fixes#14048
