| 19:38 | Add the PRAGMA table_vinfo command (with an extra "v" before "info") that works like PRAGMA table_info (without the "v") except that it also shows hidden columns on virtual tables. (check-in: 8bcd1a5956 user: drh tags: pragma-table-vinfo) | |

| 20:28 | Small size and performance optimization to sqlite3VdbeChangeP5(). (check-in: 3c93c8f5bb user: drh tags: trunk) | |
| 19:50 | Remove the peep-hole optimization of removing OP_Close opcodes that come before OP_Halt, as the extra work of removing those opcodes uses more cycles than just running them. (check-in: 984a96d796 user: drh tags: trunk) | |

This condition was not always true after all.....
Change an always-true condition in the virtual table transaction interface into an assert(). (Closed-Leaf check-in: 3e15dea55c user: drh tags: mistake) | |
| 17:20 | Use symbolic names XN_ROWID and XN_EXPR in place of the (-1) and (-2) magic numbers in Index.aiColumn[]. Add asserts to help verify that Index.aiColumn[] is always used correctly. Fix one place in FK processing where Index.aiColumn[] was not being used correctly. (check-in: 7d272aa62c user: drh tags: trunk) | |
| 17:04 | • Edit [0e317dda5dfd35b7|0e317dda5d]: Mark "Closed". (artifact: a50b98e127 user: drh) | |
| 16:47 | Add the sqlite3_index_info.idxFlags field, allowing xBestIndex() implementations to specify to SQLite that a strategy may visit at most one row. Add support for this to fts3/4. Omit the statement journal from virtual table UPDATE and DELETE operations that are guaranteed not to affect more than one row. (check-in: a1d08fd3d0 user: dan tags: trunk) | |
| 16:41 | Ensure that the xSavepoint() virtual table method is correctly invoked if there are already open savepoints (or statement transactions) the first time a virtual table is written within a transaction. (check-in: 77948b5ece user: dan tags: trunk) | |
| 15:50 | Remove dead code, replacing with assert() statements that make sure the code really was dead. (Closed-Leaf check-in: 0e317dda5d user: drh tags: vtab-onepass) | |
| 13:25 | Create the sqlite3IsToplevel(Parse*) interface to check to see if a top-level VDBE is being coded (versus a trigger) and use that interface. (check-in: 59662cd2b6 user: drh tags: vtab-onepass) | |
| 12:32 | Fix compiler warnings. (check-in: d1a0783854 user: drh tags: vtab-onepass) | |
| 12:19 | Fix an off-by-one error in test function fts5_decode(). (check-in: 3a9f076250 user: dan tags: trunk) | |
| 11:59 | Merge latest trunk change into this branch. (check-in: b519c0d67a user: dan tags: vtab-onepass) | |
| 11:57 | Change the name of the new sqlite3_index_info.flags field to "idxFlags". Add documentation for the same to sqlite.h.in. (check-in: f61203bc0f user: dan tags: vtab-onepass) | |
| 10:11 | Add tests for fts3 and onepass update/delete operations. Also fix a problem with onepass updates that do not affect any rows. (check-in: 820c804468 user: dan tags: vtab-onepass) | |

| 18:47 | Add the OPFLAG_MULTICOLUMN flag to the OP_Column opcode. Rearrange OP_Column instructions to take advantage of the new flag for a small performance increase (Leaf check-in: 5e5d6e8680 user: drh tags: faster-OP_Column) | |
| 15:42 | Fix the header comment in sqlite3VdbeDeletePriorOpcode(). No changes to code. (check-in: 7fb1626866 user: drh tags: trunk) | |
| 15:00 | Ensure that the OP_Prev opcode verifies that content has not been deleted out from under the cursor. Fix for ticket [209d31e3161b9e9ff]. (check-in: 414f0d6a64 user: drh tags: trunk) | |
| 15:00 | • Fixed ticket [209d31e316]: Assertion fault when deleting a table out from under a SELECT plus 5 other changes (artifact: 12f3314f7e user: drh) | |

| 15:41 | Check that a unique index uses the default collation sequences for each column before using it as part of a foreign key constraint operation. (check-in: 64154174cf user: dan tags: trunk) | |
