| 15:57 | Make sure that NULL results from OP_Column are fully and completely NULL and do not have the MEM_Ephem bit set. Fix for ticket [094d39a4c95ee4]. (check-in: 42705fd7 user: drh tags: trunk) | |
| 14:19 | Add a test case to check that the previous commit is effective. (check-in: 948d6e5d user: dan tags: trunk) | |
| 13:13 | Enhance whereLoopCheaperProperSubset(X,Y) so that it does not report true if X uses skip-scan less than Y, since in that case X might deserve to be cheaper even if it is a proper subset. (check-in: c106b755 user: drh tags: trunk) | |
| 09:07 | Add the ".scanstats on" command to the shell tool. Executing this command causes the shell tool to print values from sqlite3_stmt_scanstatus() after each query is run. (check-in: 7974c0ed user: dan tags: trunk) | |
|

| 15:33 | Add further tests. Fixes so that compilation without ENABLE_STMT_SCANSTATUS works. (check-in: a2303c71 user: dan tags: scanstatus) | |
| 14:46 | Use exponential buffer size growth in StrAccum, as long as the size does not grow to large, to avoid excess memory allocation resize operations. Also, document the fact that setting scratch memory causes SQLite to try to avoid large memory allocations. (check-in: a518bc33 user: drh tags: trunk) | |
| 13:24 | When enlarging the size of a StrAccum object, use sqlite3DbMallocSize() to record the entire size of the allocation, not just the requested size. (check-in: 3dda3c93 user: drh tags: trunk) | |
| 11:25 | Remove unused variable from struct WhereInfo. Add some explanatory comments to new code. (check-in: f5313e0c user: dan tags: scanstatus) | |
|
2014-11-01
| ||
| 21:00 | Minor performance enhancements to SQLITE_ENABLE_STMT_SCANSTATUS code. (check-in: f13d6ba8 user: dan tags: scanstatus) | |
| 20:38 | If SQLITE_ENABLE_STMT_SCANSTATUS is defined, record the number of times each VDBE opcode is executed. Derive the values returned by sqlite3_stmt_scanstatus() from these records on demand. (check-in: 9ea37422 user: dan tags: scanstatus) | |

| 00:05 | In the balance_nonroot() routine, protect the values in aPgno[] array from change during the page sort, so that aPgno[] can be used to avoid unnecessary pointer-map updates for auto_vacuum databases. (check-in: 69c3924f user: drh tags: trunk) | |
|
2014-10-30
| ||
| 23:14 | Improvements to the wording of some comments. Reinstate an assert() that is only true for non-corrupt database files by adding an "|| CORRUPT_DB" term. (check-in: 67adb448 user: drh tags: trunk) | |

| 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) | |
| 01:07 | Call fsync() right after ftruncate() when in journal_mode=TRUNCATE and when synchronous=FULL in order to ensure that transactions are durable across a power loss that happens moments after the commit.

| 00:58 | 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.

| 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) | |
| 19:57 | Change the 0x800 bit of SQLITE_TESTCTRL_OPTIMIZATIONS so that it disables the loading of STAT3 and STAT4 content, not just the using of that content. Change the internal name of that bit to SQLITE_Stat34. (check-in: ca3b00c4 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) | |
