|
2014-10-30
| ||

| 01:13 | In the OP_Column opcode, when extracting a field that is past the end of a short record (because the row was originally inserted prior to ALTER TABLE ADD COLUMN) then make sure the output register is fully NULL and does not contain leftover flags (such as MEM_Ephem) from its previous use. Fix for ticket [43107840f1c02]. This is a cherrypick of check-in [24780f8ddc1683fc]. (check-in: 304ea6ba user: drh tags: branch-3.8.7) | |

| 11:25 | Add test file e_wal.test. (check-in: fc6920b5 user: dan tags: trunk) | |
| 08:02 | If a free-slot is found within a page, but using that free-slot would fragment the page further and there are already at least 60 fragmented bytes, degragment the page. This matches the behaviour of the trunk. (Closed-Leaf check-in: 1f80f8c1 user: dan tags: defrag-opt) | |
| 07:01 | Merge trunk with this branch. (check-in: a13df301 user: dan tags: defrag-opt) | |

|
2014-10-22
| ||
| 20:07 | Disable the use of strchrnul() unless specifically enabled by compile-time options. (check-in: e580470d user: drh tags: trunk) | |

| 18:42 | Merge latest trunk with this branch. (check-in: 854a54c6 user: dan tags: defrag-opt) | |
| 16:25 | The _beginthreadex() / _endthreadex() functions should only be used when compiling with MSVC. (Closed-Leaf check-in: 1a5a5da3 user: mistachkin tags: msvcThreads) | |

| 01:05 | If a skip-scan is a proper subset of some other scan, then adjust the cost of the skip-scan upward so that it is more costly than the other scan. Such a cost imbalance can arise under STAT4 because of difficulties in getting an accurate estimate for skip-scans. (check-in: f4b22a26 user: drh tags: trunk) | |
