Sometimes I want to pass a different implementation of `mkNugetDeps`.
For example in private repos, it can be handy to use `__noChroot = true`
and bypass the deps.nix generation altogether. Or some Nuget packages
ship with ELF binaries that need to be patched, and that's best done as
soon as possible.
Currently `buildPerlPackage` prefixes the Perl version to the package's
`pname`, which results in `nix run` not being able to work for any
packages build with it out of the box. This commit corrects that and
phases out the ability to set `name` directly, as well as refactors the
code to not require `cleanedAttrs`.
The example snippet will fail with this error as it is not self contained and
assumes `shadowSetup` was given:
$ nix-build docker-image.nix
error: undefined variable 'shadowSetup' at docker-image.nix:20:7
Instead use the full reference to `shadowSetup` in the example so it will work
as stated.
This commit clarifies that the meaning of the `meta.sourceProvenance`
field is independent of and unaffected by the value of the
`meta.license` field. This is based on the intent of the RFC author
as expressed here:
https://github.com/NixOS/nixpkgs/pull/161098#issuecomment-1081270201
This clarification is added for two reasons:
1. If in the future there should be some disagreement about what
`sourceProvenance` to assign to a package, this may help resolve
the disagreement. Any interpretation of `sourceProvenance` which
is influenced by the `meta.license` is clearly an incorrect
interpretation.
2. If it should turn out that it is impossible to disentangle
`sourceProvenance` from `meta.license`, this would indicate the
need for changes to the `sourceProvenance` scheme. That change
might be as simple as replacing the sentence added by this commit
with some other sentence explaining how the two fields influence
each other.
This commit implements the recommendation made in the paragraph of
this comments which begins with "Please say this explicitly...":
