sha256:51ce277f663e01a43eaffbe77509b1de7ac2d4251b55d23306304bcdeb92c90d feat(pack): delta-encode snapshots in MPackBundle wire format Sonnet 4.6 minor ⚠ breaking 121 days ago
1 """Tests for Bug 8: CommitRecord.from_dict silently substitutes now() for an
2 unparseable committed_at, producing a CommitRecord whose hash never matches
3 the stored commit_id. When this record is written via apply_mpack → write_commit,
4 the commit becomes permanently unreadable — every subsequent read_commit returns
5 None because _verify_commit_id always fails.
6
7 Scope of tests
8 --------------
9 Unit (from_dict):
10 - from_dict raises ValueError on empty committed_at
11 - from_dict raises ValueError on non-ISO committed_at
12 - from_dict raises ValueError on null/None committed_at (dict value)
13 - from_dict succeeds with a valid committed_at
14 - from_dict succeeds with a timezone-aware committed_at
15
16 Integration (write_commit incoming verification):
17 - write_commit rejects a record whose hash doesn't match commit_id (new file)
18 - write_commit rejects a record whose hash doesn't match commit_id (existing good file)
19 - write_commit accepts a record whose hash matches commit_id (no file)
20 - write_commit accepts a record whose hash matches commit_id (idempotent)
21
22 End-to-end (apply_mpack):
23 - apply_mpack skips a commit with missing committed_at (no crash, no write)
24 - apply_mpack skips a commit with garbage committed_at
25 - apply_mpack writes a commit with valid committed_at and it is readable
26 - apply_mpack does not skip valid commits when one commit in bundle is corrupt
27
28 Data integrity:
29 - A commit written via apply_mpack from a bundle with valid fields is readable
30 - A corrupt bundle cannot poison an existing good commit
31
32 Regression:
33 - SnapshotRecord.from_dict silent created_at substitution: snapshot still
34 readable (created_at is NOT in hash so this doesn't break verification,
35 but timestamp should be correctable)
36 - CommitRecord.from_msgpack still raises on corrupt committed_at (regression
37 guard for Bug 6 fix)
38
39 Performance (stress):
40 - 200-commit bundle with one corrupt committed_at: 199 commits written, 1 skipped
