20 check-ins using file src/vdbeInt.h version 539ba284

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) | |

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) | |

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) | |
16:39 | Fix a typo preventing this from building with SQLITE_ENABLE_STMT_SCANSTATUS defined. (Closed-Leaf check-in: 4c5714ab user: dan tags: scanstatus) | |
16:35 | Refactor the interface to make it more easily extensible. (check-in: 7955342d user: drh tags: scanstatus) | |
15:33 | Add further tests. Fixes so that compilation without ENABLE_STMT_SCANSTATUS works. (check-in: a2303c71 user: dan tags: scanstatus) | |
11:25 | Remove unused variable from struct WhereInfo. Add some explanatory comments to new code. (check-in: f5313e0c user: dan tags: scanstatus) | |
