Add an immutable tarball link to archive download headers for Nix This allows `nix flake metadata` and nix in general to lock a *branch* tarball link in a manner that causes it to fetch the correct commit even if the branch is updated with a newer version. For further context, Nix flakes are a feature that, among other things, allows for "inputs" that are "github:someuser/somerepo", "https://some-tarball-service/some-tarball.tar.gz", "sourcehut:~meow/nya" or similar. This feature allows our users to fetch tarballs of git-based inputs to their builds rather than using git to fetch them, saving significant download time. There is presently no gitea or forgejo specific fetcher in Nix, and we don't particularly wish to have one. Ideally (as a developer on a Nix implementation myself) we could just use the generic tarball fetcher and not add specific forgejo support, but to do so, we need additional metadata to know which commit a given *branch* tarball represents, which is the purpose of the Link header added here. The result of this patch is that a Nix user can specify `inputs.something.url = "https://forgejo-host/some/project/archive/main.tar.gz"` in flake.nix and get a link to some concrete tarball for the actual commit in the lock file, then when they run `nix flake update` in the future, they will get the latest commit in that branch.

Redesign Scoped Access Tokens (#24767) ## Changes - Adds the following high level access scopes, each with `read` and `write` levels: - `activitypub` - `admin` (hidden if user is not a site admin) - `misc` - `notification` - `organization` - `package` - `issue` - `repository` - `user` - Adds new middleware function `tokenRequiresScopes()` in addition to `reqToken()` - `tokenRequiresScopes()` is used for each high-level api section - _if_ a scoped token is present, checks that the required scope is included based on the section and HTTP method - `reqToken()` is used for individual routes - checks that required authentication is present (but does not check scope levels as this will already have been handled by `tokenRequiresScopes()` - Adds migration to convert old scoped access tokens to the new set of scopes - Updates the user interface for scope selection ### User interface example <img width="903" alt="Screen Shot 2023-05-31 at 1 56 55 PM" src="https://github.com/go-gitea/gitea/assets/23248839/654766ec-2143-4f59-9037-3b51600e32f3"> <img width="917" alt="Screen Shot 2023-05-31 at 1 56 43 PM" src="https://github.com/go-gitea/gitea/assets/23248839/1ad64081-012c-4a73-b393-66b30352654c"> ## tokenRequiresScopes Design Decision - `tokenRequiresScopes()` was added to more reliably cover api routes. For an incoming request, this function uses the given scope category (say `AccessTokenScopeCategoryOrganization`) and the HTTP method (say `DELETE`) and verifies that any scoped tokens in use include `delete:organization`. - `reqToken()` is used to enforce auth for individual routes that require it. If a scoped token is not present for a request, `tokenRequiresScopes()` will not return an error ## TODO - [x] Alphabetize scope categories - [x] Change 'public repos only' to a radio button (private vs public). Also expand this to organizations - [X] Disable token creation if no scopes selected. Alternatively, show warning - [x] `reqToken()` is missing from many `POST/DELETE` routes in the api. `tokenRequiresScopes()` only checks that a given token has the correct scope, `reqToken()` must be used to check that a token (or some other auth) is present. - _This should be addressed in this PR_ - [x] The migration should be reviewed very carefully in order to minimize access changes to existing user tokens. - _This should be addressed in this PR_ - [x] Link to api to swagger documentation, clarify what read/write/delete levels correspond to - [x] Review cases where more than one scope is needed as this directly deviates from the api definition. - _This should be addressed in this PR_ - For example: ```go m.Group("/users/{username}/orgs", func() { m.Get("", reqToken(), org.ListUserOrgs) m.Get("/{org}/permissions", reqToken(), org.GetUserOrgsPermissions) }, tokenRequiresScopes(auth_model.AccessTokenScopeCategoryUser, auth_model.AccessTokenScopeCategoryOrganization), context_service.UserAssignmentAPI()) ``` ## Future improvements - [ ] Add required scopes to swagger documentation - [ ] Redesign `reqToken()` to be opt-out rather than opt-in - [ ] Subdivide scopes like `repository` - [ ] Once a token is created, if it has no scopes, we should display text instead of an empty bullet point - [ ] If the 'public repos only' option is selected, should read categories be selected by default Closes #24501 Closes #24799 Co-authored-by: Jonathan Tran <jon@allspice.io> Co-authored-by: Kyle D <kdumontnu@gmail.com> Co-authored-by: silverwind <me@silverwind.io>
