| 13:48 | Do not leave a WITHOUT ROWID table without a primary key index structure due to an OOM error. This prevents downstream troubles in the case of PRAGMA writable_schema=ON. dbsqlfuzz 69fb32cc82d59b4d790881566e3f6c727e616122 (check-in: 608b6644b9 user: drh tags: trunk) | |

| 18:32 | Avoid taking the address of a NULL pointer following an OOM in FTS5. Doing so is harmless in actual practice, but it technically UB so we want to avoid it. (check-in: 1cfcd9dceb user: drh tags: trunk) | |

| 11:51 | Fix harmless comment typo in main.c. (check-in: 785a553e71 user: drh tags: trunk) | |

| 22:20 | Remove an ALWAYS() that is actually reachable following an OOM on an UPDATE FROM of a virtual table. dbsqlfuzz aa03237ef7c4a028c7cdaf8bbcde2b62e2bcd36e (check-in: 49eac38926 user: drh tags: trunk) | |
| 20:50 | Have the VFS in memdb.c return SQLITE_IOERR_NOMEM instead of SQLITE_NOMEM when an OOM error is encountered. This is required to get the pager module to handle such OOM errors correctly in some cases. (check-in: 09c96b4c02 user: dan tags: trunk) | |
