feat(mix): Support private hex repos/registries

[bryannaegele]

Changes

This adds support to the mix manager to add private hex repos/registries via registryAliases for mapping and hostRules for authentication.

Context

This is the companion to #29756 and dependent on that change. Splitting the manager and datasource work per request in #29756. When combined, this will enable support for private repos/registries such as oban pro.

Documentation (please check one with an [x])

• I have updated the documentation, or
• No documentation update is required

How I've tested my work (please select one)

I have verified these changes via:

• Code inspection only, or
• Newly added/modified unit tests, or
• No unit tests but ran on a real repository, or
• Both unit tests + ran on a real repository

Tested in combination with #29756. This will not fully work without that code.

Feedback should be addressed 👍🏻

[viceice]

this should be scoped to mix manager, otherwise it will interferre with other managers using registry aliases

[bryannaegele]

So there needs to be a further nesting of the object? I didn't see any examples of that in other managers

@bryannaegele are you still working on this?
I have the same/very similar use case and I'd love renovate to support elixir correctly.

this particular change can be observed here https://github.com/renovatebot/renovate/blob/main/docs/usage/configuration-options.md#registryaliases
IMO this is what viceice is asking about.

Suggested change

	registryAliases: {
	oban: 'https://getoban.pro/repo',
	},
	{
	"mix": {
	registryAliases: {
	oban: 'https://getoban.pro/repo',
	},
	}
	}

why is this needed

[bryannaegele]

We need the URL for the hexpm registry, which is the default, so we put it into the default config. This is merged with anything the user has supplied, giving us a complete lookup of the URLs. This has an added benefit that if a company wished to host an internal proxy registry, no updates are needed to their mix files; they have a way to point someplace else.

[viceice]

you should not add a default url, the datasource has it already, so only set registry url if it's not the default

[viceice]

this is used by the hex datasource, so needs changes there too

renovate/lib/modules/datasource/hex/index.ts

Line 45 in 302718f

const [hexPackageName, organizationName] = packageName.split(':');

[bryannaegele]

That is in the other PR. You requested to split them so neither PR will work on its own

[viceice]

then don't change package name in this PR, do the package name change in a separate refactor PR

[bryannaegele]

So neither PR is backwards compatible with the other. They are both dependent on the format change. If we don't change this here then your proposed refactor PR just pushes the change both need to make into a single PR that touches the datasource and manager.

this MR is closed, what s the plan? is there a solution merged? what s the end result?
