| 1 | """TDD -- musehub#220: create_repo(initialize=True) seeded every new repo |
| 2 | with a structurally invalid genesis commit -- no snapshot_id, no |
| 3 | MusehubSnapshot row, and (found during investigation, same ticket) a |
| 4 | commit_id computed by a hand-rolled hash that doesn't match what a real |
| 5 | client recomputes via hash_commit() on clone/fetch. |
| 6 | |
| 7 | The second bug is in commit_files_to_repo itself -- shared by org |
| 8 | creation, org membership changes, and identity-repo creation at |
| 9 | registration. Every commit ever created through it would fail content-hash |
| 10 | verification ("Commit ... failed content-hash verification") the moment |
| 11 | any real client tried to store it locally (clone, pull). Fixed at the |
| 12 | source so every caller benefits, not just create_repo. |
| 13 | |
| 14 | Test IDs: |
| 15 | RC_01 -- create_repo(initialize=True) commit has a non-empty snapshot_id |
| 16 | RC_02 -- that snapshot_id resolves to a real MusehubSnapshot row (empty manifest) |
| 17 | RC_03 -- the commit_id is exactly what a real client's hash_commit() recomputes |
| 18 | from the stored fields (the actual _verify_commit_id check, reproduced) |
| 19 | RC_04 -- commit_files_to_repo's own commit_id (independent of create_repo) |
| 20 | also passes the same recomputation check -- the shared root-cause fix |
| 21 | RC_05 -- create_repo(initialize=False) still creates zero commits (unchanged) |
