Add private API endpoints for admin tasks

[Turbo87]

Heroku allows us to perform one-off tasks directly on the server, and we have the crates-admin binary in this project which allows this. This tool locks us into platforms that support this kind of direct server access though, which would make it harder for us to potentially switch hosting providers in the future.

The way to resolve this problem is to convert all of the existing tools in crates-admin into private API endpoints. These endpoints should be protected by checking if the current user is part of a specific GitHub team.

These are the tools that will need to be converted:

• delete_crate
• delete_version
• populate
• render_readmes
• test_pagerduty
• transfer_crates
• verify_token
• Increase rate limit - @carols10cents is working on this in WIP: Admin interface #5376
• Lock/unlock account

render_readmes appears to be somewhat special here because it is a potentially long-running operation. Converting this might involve creating a new swirl background task that performs the actual operation.

I am working on this.

Hi @Turbo87 I was thinking in working on this issue. Is this one still relevant?

I was going over the requirements, my understanding is that the relationship between users and teams are not mapped in the database. To do the authorisation for this ticket we would need a method similar to team_with_gh_id_contains_user. Is that a correct assumption?

One last question: Would you prefer have one PR for each endpoint or a single PR with all endpoints implemented?

Thanks

yeah, I guess it is.

for a first implementation it would probably be sufficient to just hardcode the list of admin user accounts. we can still enhance it later if necessary :)

Would you prefer have one PR for each endpoint or a single PR with all endpoints implemented?

definitely one PR per endpoint. the smaller the PRs are the more likely it will be to get quick reviews 😉

in general I recommend have a look at and roughly following the suggestions in https://mtlynch.io/code-review-love/ :)

I've actually gotten started on this but I'd love help; I'm really slow. Here's my branch if you want to work off of it: #5376

[mario-areias]

Oh I didn't know you were working on it @carols10cents, my apologies. Thanks for sending that PR it is good for me to learn from your approach in solving this problem 🙏

Appreciate you sharing your branch, but I am looking for a ticket that I can implement in Rust only (which I thought this ticket was). I am avoiding JavaScript for now because I want to avoid learning two code bases at the same time and want to focus on Rust first. So it may be better you finish this ticket since it has some JavaScript involved. I will try to find another ticket else I can focus on. Hope that's okay 😄

[carols10cents]

Don't be sorry, there's no way you could have known :)

It's up to you, but like I said, I'm slow, so I'd love help even if it's just with the backend. In fact, I'd prefer if each one of these backend endpoints was its own PR!

Since this admin panel will provide sensitive functionality, what are your thoughts on using a different cookie to allow access to it? The current cargo_session cookie has a pretty lengthy lifespan.

If we used a separate cookie, for example cargo_admin, with a short lifespan of an hour or less this would help mitigate session hijacking threats.

[carols10cents]

Sure, sounds great!

If we used a separate cookie, for example cargo_admin, with a short lifespan of an hour or less this would help mitigate session hijacking threats.

that would introduce a third authentication option though, which I assume would make our auth code even more complicated. but I'm happy to be wrong about this if you can come up with a simple solution :)
