| 1 | //! What a personal access token reaches, and the rules a workspace sets for |
| 2 | //! the tokens that reach it. See `g1t_contracts::tokens`. |
| 3 | //! |
| 4 | //! **Classic tokens** reach whatever their owner can, narrowed by their |
| 5 | //! scopes. **Fine-grained tokens** (migration 0034) name one resource owner |
| 6 | //! (their owner's own account, or one workspace), all, selected or only |
| 7 | //! public repositories of it, and a level for each permission, stored as |
| 8 | //! the scopes those give. Migration 0023 had retired a token's reach in |
| 9 | //! favour of classic tokens only; the owner chose GitHub's model instead, |
| 10 | //! with both kinds side by side. |
| 11 | //! |
| 12 | //! Each time a token is used, [`Identity::apply_reach`] cuts the person it |
| 13 | //! resolves to down to what it reaches: a fine-grained token keeps only its |
| 14 | //! resource owner's membership and grants (none while it waits for |
| 15 | //! approval), and any personal token loses the workspaces whose rules keep |
| 16 | //! it out (a kind they do not allow, a lifetime past their limit, or an |
| 17 | //! owner revoking it there). Services then decide as for anyone, and |
| 18 | //! `access::granted` holds a fine-grained token to its repositories. |
| 19 | //! |
| 20 | //! **Approval.** A fine-grained token naming a workspace that asks for |
| 21 | //! approval starts pending, unless its owner is an owner there. The |
| 22 | //! workspace's owners hear of it in their inbox (`token.approval_requested`) |
| 23 | //! and approve or deny it; its owner hears back |
| 24 | //! (`token.approval_reviewed`). Changing a token's repositories or |
| 25 | //! permissions asks again. |
