| 19:17 | Make sure signed integer overflow does not cause a segfault while attempting to read a corrupt database where the header size varint on a record is larger than the maximum 32-bit signed integer. (check-in: c3baca99 user: drh tags: trunk) | |
| 17:43 | Add test case for the problem fixed by [127a5b776d]. (check-in: 65816718 user: dan tags: trunk) | |
| 17:21 | An improved method for avoiding the use of the STAT3 samples to compute the estimated number of outputs when the left-most index is equality constrained. This check-in undoes the previous fix and applies a new one. (check-in: 127a5b77 user: drh tags: trunk) | |
