feat(ubi): add support for self-hosted GitHub/GitLab

[roele]

Fixes #4749

[roele]

I just gave this a spin this morning with a test binary.

[tools]
"ubi:gitlab-org/cli" = { version = "latest", exe = "glab", provider = "gitlab" }

Just adding the UBI forge support is not enough since mise fetches release versions to do the outdated check. So we also need an implementation of the GitLab API to fetch releases/tags and incorporate this into _list_remote_versions implementation. This extends further to the GitHub/GitLab implementations we use with a fixed API URL. Allowing for enterprise support would mean that we also need to fetch releases/tags from a custom URL. Thinking even further some enterprises are usually not on the latest API versions etc.

What i have a hard time with is that self.ba.opts() does not return anything within _list_remote_versions, so also the opts.get("tag_regex") in this method would not work.

@jdx Maybe you can shed some light on the concept of options. There is a BackendArg.opts() and a ToolRequest.options(). They seem to be the same thing but are not synced.

If i add the following example to my mise.toml

"ubi:gitlab-org/cli" = { version = "1.54.0", exe = "glab", provider = "gitlab" }

i get the error

cd mise
mise ERROR [~/Downloads/mise/mise.toml] ubi:gitlab-org/[email protected]: HTTP status client error (404 Not Found) for url (https://api.github.com/repos/gitlab-org/cli/releases)
mise ERROR error resolving versions
mise ERROR Run with --verbose or MISE_VERBOSE=1 for more information

this is due to the fact that BackendArgs.opts() used when listing remote versions is empty, it would expect options in the backend string like ubi:gitlab-org/cli[exe=glab,provider=gitlab]

Currently to get this working without errors one might need to define the following which IMO is redundant.

"ubi:gitlab-org/cli[exe=glab,provider=gitlab]" = { version = "1.54.0", exe = "glab", provider = "gitlab" }

[jdx]

yeah I think what we should do is probably have tool options include all of the backend opts

[roele]

The problem i currently face is the other way around. Under some circumstances (uncached tool) the following code block is called, where BackendArgs.opts() is empty and i don't have access to the ToolRequest which contains the options for the provider and API URL.

mise/src/backend/ubi.rs

Line 41 in 370214d

let opts = self.ba.opts();

[jdx]

I see. I don't think it would be possible to get the tool options at that point since mise doesn't necessarily have a specific tool when finding the versions. Maybe when we parse the toml we could include the tool options on the backend arg?

Turned out to be more work than anticipated but it should be working by now. Had to extend http.rs slightly since Github authentication was hardcoded. Only thing i could not test/verify properly is the token handling for the self-hosted URLs.
