| 19:02 | Simplify the row value misuse error message. (check-in: 838c50a5bf user: drh tags: rowvalue) | |
| 18:30 | Fix a problem with rowvalue UPDATE when the rowvalue is not the left-most and the RHS is a multi-column subquery. (check-in: e149e6b93a user: drh tags: rowvalue) | |
| 17:30 | Fix an uninitialized variable in CASE expression code generation. (check-in: c8ffae05e1 user: drh tags: rowvalue) | |
|
2016-08-22
| ||
| 14:30 | Fix the vector BETWEEN operator so that it only evaluates the left-most vector expression once. Add support for vector comparisons in the CASE operator. (check-in: 07e69f43a2 user: drh tags: rowvalue) | |
| 00:48 | Reinstate the mechanism in BETWEEN that avoids evaluating the first expression more than once, but fix the affinity extractor so that it works with this mechanism. The de-duplication of the first expression still does not work for vector expressions, though. (check-in: 2f39987f21 user: drh tags: rowvalue) | |
|
2016-08-20
| ||
| 22:49 | The docs promise the in "x BETWEEN y AND z" the x expression is only evaluated once. That is no longer true, and so some tests are failing. This needs to be fixed before merging to trunk. (check-in: e50d264fdc user: drh tags: rowvalue) | |
| 21:11 | Further comment enhancements. No changes to code. (check-in: d4562a9e7b user: drh tags: rowvalue) | |

| 17:55 | Display VECTOR expressions in .wheretrace and .selecttrace debugging output. (check-in: 157347e258 user: drh tags: rowvalue) | |
| 15:36 | Since the TK_VECTOR token is not actually used by the parser, make it an extra token code added by the tool/addopcodes.tcl script during parser build. (check-in: b40b202c1f user: drh tags: rowvalue) | |
| 15:21 | Merge recent enhancements from trunk. (check-in: 4768a1066c user: drh tags: rowvalue) | |

| 10:02 | Attempt to simplify the logic and generated code for vector comparisons. Basic comparison operators are working, but there are many indexing test failures still to be worked through. (check-in: dfc028cfbe user: drh tags: vector-compare) | |

| 15:02 | Tweaks to pcache1TruncateUnsafe() to make it slightly smaller and faster and easier to test. (check-in: 059f4e2efe user: drh tags: trunk) | |
| 14:40 | Rearrange the code inside sqlite3RunParser() routine so that sqlite3Parser() is only called from a single place. This allows sqlite3Parser() to be in-lined, which results in a 0.25% overall performance gain. (check-in: 25d1d02b3e user: drh tags: trunk) | |
| 13:34 | Increment the version number to 3.15. (check-in: 8c2701e70a user: drh tags: trunk) | |

| 20:54 | Have the TEA package build without SQLITE_OMIT_DEPRECATED. As it uses recently deprecated interfaces sqlite3_profile() and sqlite3_trace(). (check-in: 9557889883 user: dan tags: trunk) | |
| 16:16 | Undo commit [f250166bb]. It is required to handle IO and other errors that occur within a VACUUM of a Zipvfs database. (check-in: ae72513af3 user: dan tags: trunk) | |

| 13:23 | Revert the SQLITE_APICALL changes for now. That changes needs further research before it is released. Deferred until 3.15. (check-in: 9adda38526 user: drh tags: trunk) | |
| 12:35 | Add the experimental SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option. When enabled, the "unknown function" error is suppressed for EXPLAIN and a no-op function named "unknown()" is substituted. This facilitiates using the command-line shell to analyze queries from applications that contain many application-defined functions that are not normally available to the shell. (check-in: b7f30a9ff2 user: drh tags: trunk) | |
| 09:09 | Make sure the ORDER BY LIMIT optimization is not applied if the inner-most loop can only have a single iteration and is hence not really a loop. (check-in: 13e3bd3de6 user: drh tags: trunk) | |
| 01:47 | Add an experimental SQLITE_ENABLE_UNKNOWN_SQL_FUNCTION compile-time option. This changes has been merged into main branches via cherry-pick. (Closed-Leaf check-in: 4ada023ca0 user: drh tags: unknown-function) | |
