| 09:37 | Add an extra snapshot related test case. (check-in: 24a95e1437 user: dan tags: trunk) | |
|
2017-09-23
| ||
| 07:46 | Experimental change so that snapshot transactions always lock the wal file - preventing writers or truncate-checkpointers from wrapping it. (Closed-Leaf check-in: d71eeaab9e user: dan tags: snapshots-lock-wal) | |

| 20:18 | Merge in all the trunk enhancements of the previous 7 months. The LIKE optimization has stopped working when there is an ESCAPE - that problem will be addressed in a subsequent check-in. (Leaf check-in: 8d2a1cca61 user: drh tags: est_count_pragma) | |
| 16:23 | Use the updated Win32 VFS semantics for winOpen from check-in [5d03c738e9] for WinRT, et al, as well. (check-in: 2c03d8b8f0 user: mistachkin tags: trunk) | |
| 12:52 | Partial backout of check-in [e0af9a904076]. It turns out we do need some extra space at the end of the record blob as an overrun area to use when decoding a maliciously malformed record. (check-in: 403b88a894 user: drh tags: trunk) | |
