| 19:26 | Change the query planner to do a better job of estimating the number rows selected by a BETWEEN operator using STAT4 when both upper and lower bounds are contained within the same sample. (check-in: 2d36be5d9a user: drh tags: trunk) | |
| 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: 42705fd7d8 user: drh tags: trunk) | |
| 14:19 | Add a test case to check that the previous commit is effective. (check-in: 948d6e5d07 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: c106b75536 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: 7974c0ed10 user: dan tags: trunk) | |

| 21:38 | Improved output formatting for the showstat4 tool. (check-in: 7df82c46da user: drh tags: trunk) | |
| 19:52 | Skip tests that require WAL mode when it is not enabled. (Closed-Leaf check-in: 6fc4ead26d user: mistachkin tags: winMmapNoWal) | |
| 19:37 | For the Win32 VFS, allow memory mapped files to work when compiled without WAL support. (check-in: 1fc7e2f3d3 user: mistachkin tags: winMmapNoWal) | |
| 17:23 | Add various requirements evidence marks for sqlite3_config() options. (check-in: d423349d2c user: drh tags: trunk) | |
| 14:22 | Change the definition of SQLITE_CONFIG_SCRATCH so that at most one scratch buffer is used per thread. Use the generic heap memory allocator for the WalIterator object when running a checkpoint. (check-in: 391c9b85ab user: drh tags: trunk) | |
| 13:41 | Improved documentation and addition of source-code evidence marks for the sqlite3_config() interface. (check-in: 681031a436 user: drh tags: trunk) | |
| 12:11 | Add the SQLITE_CONFIG_PCACHE_HDRSZ option for sqlite3_config(). (check-in: 6eb03e62a3 user: drh tags: trunk) | |
|

| 16:35 | Refactor the interface to make it more easily extensible. (check-in: 7955342da4 user: drh tags: scanstatus) | |
| 15:33 | Add further tests. Fixes so that compilation without ENABLE_STMT_SCANSTATUS works. (check-in: a2303c7192 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: a518bc3318 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: 3dda3c9374 user: drh tags: trunk) | |
| 11:25 | Remove unused variable from struct WhereInfo. Add some explanatory comments to new code. (check-in: f5313e0c68 user: dan tags: scanstatus) | |
|

| 21:00 | Minor performance enhancements to SQLITE_ENABLE_STMT_SCANSTATUS code. (check-in: f13d6ba8a7 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: 9ea37422a8 user: dan tags: scanstatus) | |
| 18:32 | Add requirements marks and make minor tweaks to documentation. (check-in: 49188b2bb5 user: drh tags: trunk) | |

| 14:53 | Merge recent trunk enhancements, and in particular the improvements to the b-tree balancing logic, into the sessions branch. (check-in: 28b044a512 user: drh tags: sessions) | |
| 14:46 | Change the command-line shell man-page to use the ".tr" troff directive instead of ".cc" for escaping the initial "." characters in the ".help" output. (check-in: 67f0d469da user: drh tags: trunk) | |
| 14:26 | Simplify the logic in the cell redistribution loop of balance_nonroot(). Enhance and clarify comments and add assert() statements for additional verification of correctness. (check-in: a07078b600 user: drh tags: trunk) | |
| 12:22 | Simplify the math slightly, and reduce by one the number of loop iterations, for the loop in balance_nonroot() that moves cells between pages. (check-in: 2e838db82e user: drh tags: trunk) | |
| 10:31 | Add the "varint.c" utility program in the tool directory. (check-in: ea5d56be5f user: drh tags: trunk) | |
| 02:51 | Remove an unnecessary branch from balance_nonroot(). (check-in: 9fc7c88e3f user: drh tags: trunk) | |
| 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: 69c3924fe8 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: 67adb44838 user: drh tags: trunk) | |
| 20:48 | Tweaks to comments in btree.c. Minor code changes to enhance testability. (check-in: c7d9aa3a1c user: drh tags: trunk) | |

| 13:59 | Version 3.8.7.1 (check-in: 3b7b72c468 user: drh tags: release, version-3.8.7.1, branch-3.8.7) | |
| 01:27 | Increase the version number to 3.8.7.1 (check-in: 83afe23e55 user: drh tags: branch-3.8.7) | |

| 01:18 | Disable the use of strchrnul() unless specifically enabled by compile-time options. Cherrypick of check-in [e580470db77d6da9] (check-in: 837368adfe user: drh tags: branch-3.8.7) | |
| 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: 304ea6ba6f 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.
