| 13:52 | In the ".scanstats on" output from the shell, round the estRows value to the nearest integer, rather than rounding toward zero. (check-in: 57005085 user: drh tags: trunk) | |
| 13:24 | Fix harmless typos in comments. (check-in: 94c564da user: drh tags: trunk) | |
| 11:39 | Fix typo in sqlite3.h reported on the mailing list. (check-in: 40270321 user: drh tags: trunk) | |
| 01:43 | Update documentation on sqlite3_config() and add corresponding evidence marks. (check-in: 360c8ca1 user: drh tags: trunk) | |

| 14:43 | Added SQLITE_SCANSTAT_SELECTID. Change the value returned by SQLITE_SCANSTAT_EST from sqlite3_int64 to double. Enhanced the formatting and display of scan statistics using the ".scanstats on" command in the shell. (check-in: 20c7614a user: drh tags: trunk) | |
| 12:46 | Further improvements to the ".scanstats on" display in the shell. Be sure to show the results of all subqueries even if there are gaps in the SELECTID values. Add ".scanstats" to the ".help" output. (Closed-Leaf check-in: ee922682 user: drh tags: scanstatus) | |
| 12:17 | On the ".scanstats on" output in the shell, initialize the estimated count for the first loop of each subquery to the actual loop count. (check-in: d1c51c84 user: drh tags: scanstatus) | |
| 12:08 | Changes the formatting of ".scanstats on" in the shell so that the stats for subqueries are grouped together and occur after the main query. (check-in: eacbbd88 user: drh tags: scanstatus) | |
| 04:42 | Add the SQLITE_SCANSTAT_SELECTID metric. Use it to improve the ".stmtscan on" output in the shell. (check-in: 64ad5761 user: drh tags: scanstatus) | |
| 03:55 | Change the SQLITE_SCANSTAT_EST parameter so that it returns a double for the estimated number of output rows per loop, rather than a 64-bit integer. Revise the output format for the ".scanstats on" in the shell to make use of this new capability. (check-in: f9684000 user: drh tags: scanstatus) | |

| 21:34 | Fixes to the Windows VFS to allow memory mapped files to work without WAL support. (check-in: 272fddc1 user: drh tags: trunk) | |
| 21:21 | Fix harmless compiler warnings in the new balance_nonroot() routine. (check-in: 83a1e5db user: drh tags: trunk) | |
| 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: 2d36be5d 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: 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) | |
|
2014-11-04
| ||
| 21:38 | Improved output formatting for the showstat4 tool. (check-in: 7df82c46 user: drh tags: trunk) | |
| 19:52 | Skip tests that require WAL mode when it is not enabled. (Closed-Leaf check-in: 6fc4ead2 user: mistachkin tags: winMmapNoWal) | |
| 19:37 | For the Win32 VFS, allow memory mapped files to work when compiled without WAL support. (check-in: 1fc7e2f3 user: mistachkin tags: winMmapNoWal) | |
| 17:23 | Add various requirements evidence marks for sqlite3_config() options. (check-in: d423349d 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: 391c9b85 user: drh tags: trunk) | |
| 13:41 | Improved documentation and addition of source-code evidence marks for the sqlite3_config() interface. (check-in: 681031a4 user: drh tags: trunk) | |
| 12:11 | Add the SQLITE_CONFIG_PCACHE_HDRSZ option for sqlite3_config(). (check-in: 6eb03e62 user: drh tags: trunk) | |
|
2014-11-03
| ||
| 18:03 | Updates to the sqlite3_stmt_scanstatus() documentation. No changes to code. (check-in: d97c324e user: drh tags: trunk) | |
| 16:56 | Add the experimental sqlite3_stmt_scanstatus() API. For comparing the number of rows actually visited by a loop with the estimate used by the query planner. (check-in: ab3b0fc5 user: dan tags: trunk) | |
| 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) | |

| 18:32 | Add requirements marks and make minor tweaks to documentation. (check-in: 49188b2b user: drh tags: trunk) | |
