| 1 | //! A repository's lifecycle after it is made: renaming it, archiving it, |
| 2 | //! making it public or private, changing or renaming its default branch, |
| 3 | //! and deleting it with a window to restore it. |
| 4 | //! |
| 5 | //! Deleting is soft. The row gets `deleted_at` and `purge_after` |
| 6 | //! ([`RESTORE_DAYS`] on), every read in the registry leaves it out, git |
| 7 | //! refuses it, and `repo.deleted` tells every service to stop what runs for |
| 8 | //! it and hide it. Restoring clears the columns (`repo.restored`). Purging, |
| 9 | //! by an owner from the Recently deleted list or by the hourly sweep once |
| 10 | //! `purge_after` has passed, removes the git data from the store, then the |
| 11 | //! rows (its pull requests' working copies with it) and its redirects, and |
| 12 | //! announces `repo.purged`, on which services drop what they keep for it. |
| 13 | //! Until then its name stays taken, so a restore always has its path back. |
| 14 | //! |
| 15 | //! A rename is a path change like a transfer: the old path is kept in |
| 16 | //! `repo_redirects`, the git store key never changes, the tokens of agents |
| 17 | //! at work on it are moved with identity, and `repo.renamed` is handled by |
| 18 | //! services with the same helper as `repo.transferred` |
| 19 | //! (`g1t_kit::transfer`). |
