Mathieu Fenniak	ef5479af71	refactor: split "basic" and "oauth2" authentication impl into smaller single-purpose components (#12236) ... Forgejo's `basic` and `oauth2` authentication methods perform five distinct types of authentication: - Username and password authentication - Personal access tokens - OAuth2 access tokens - Forgejo Action's `${{ forgejo.token }}` -- task-based static tokens - Forgejo Action's `${{ env.ACTIONS_RUNTIME_TOKEN }}` JWT, which is the authentication method used for `upload-artifact` (mirroring GitHub's implementation) `basic` and `oauth2` both supported almost all of these methods, resulting in quite a bit of code duplication between them. This PR splits personal access tokens into `access_token.go`, Action's task-based tokens into `action_task_token.go`, and Action's JWT tokens into `action_runtime_token.go`. **Note:** There is one peculiar side-effect that is worth discussing. Previously, `Authorization: Basic ...` was handled by one complex code path in basic.go, and `Authorization: Bearer ...` was handled by another in oauth2.go, and if authorization failed and a 401 was returned, a single error message would be returned to the user. Now, as multiple authorization methods may look at `Authorization: Basic ...` and provide their own reason why authorization didn't work, a 401 response has multiple reasons for a lack of authorization listed: ``` 401 Unauthorized ... failure to authenticate with oauth2 access token: not a JWT Basic authorization is not allowed while having security keys enrolled access token does not exist [sha: notpassword] task with token "notpassword": resource does not exist ``` A couple tests have been adapted to check that the result contains their expected response, rather than is equal-to or prefixed-with their expected result. This is caused by the "auth group" joining together any "invalid credentials" errors, and, to a certain extent it is useful to understand why the authorization request failed. But it's a bit obscure as well. ## Checklist The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors.

Mathieu Fenniak	9f7533c1f1	refactor: clarify four different outputs that authentication methods provide (#12231) ... #12202 began a refactor of Forgejo's authentication implementations by providing structured data on an authentication success. However, error cases were maintained as-is in that refactor, leaving a complex situation: what does returning an error from an authentication method mean?; does it mean that the authentication failed, or that a server error occurred? Can another authentication still be tried? This PR changes authentication methods so that they can return one of four things: - `AuthenticationSuccess` with an authentication result. - `AuthenticationNotAttempted` which indicates that no credentials relevant for this authentication method were presented. If every method returned `AuthenticationNotAttempted`, then you would have an unauthenticated access. - `AuthenticationAttemptedIncorrectCredential` which indicates that credentials were present and failed validation -- a situation indicating a `401 Unauthorized`. - `AuthenticationError` which indicates that an internal server error occurred and failed authentication -- indicating a `500 Internal Server Error`. This paves the way for one more refactor coming next: `basic.go` and `oauth2.go` perform 3-4 different authentications each (access tokens, oauth JWTs, actions tokens, actions JWTs, and username/password). With the capability to return these more precise responses, these authentication methods can be split up into separate logic that isn't intertwined together. ## Checklist The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors.

Mathieu Fenniak	1ddd5faa5c	refactor: change authentication to return structured data (#12202) ... Currently authentication methods return information in two forms: they return who was authenticated as a `*user_model.User`, and then they insert key-values into `ctx.Data` which has critical impact on how the authenticated request is treated. This PR changes the authentication methods to return structured data in the form of an `AuthenticationResult`, with all the key-value information in `ctx.Data` being moved into methods on the `AuthenticationResult` interface. Authentication workflows in Forgejo are a real mess. This is the first step in trying to clean it up and make the code predictable and reasonable, and is both follow-up work that was identified from the repo-specific access tokens (where the `"ApiTokenReducer"` key-value was added), and is pre-requisite work to future JWT enhancements that are [being discussed](https://codeberg.org/forgejo/forgejo/issues/3571#issuecomment-13268004). ## Checklist The [contributor guide](https://forgejo.org/docs/next/contributor/) contains information that will be helpful to first time contributors.
