| 21:54 | Simplified VDBE code for the vector NOT IN null-scanning loop. (check-in: 7ae504e62e user: drh tags: rowvalue) | |
| 21:24 | Improved extended comments of comparison operators when the SQLITE_STOREP2 flags is set on P5. No changes to non-debug code. (check-in: bbc1b01616 user: drh tags: rowvalue) | |
| 19:58 | Modularize all use of the calling convention macros based on the USE_STDCALL nmake macro. (check-in: e4a56197b0 user: mistachkin tags: callbackConv) | |

| 19:02 | Simplify the row value misuse error message. (check-in: 838c50a5bf user: drh tags: rowvalue) | |
| 19:02 | Add further tests for changebatch. And a fix to prevent a changeset from conflicting with itself. (check-in: 506d6ff4b6 user: dan tags: changebatch) | |
| 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) | |
| 18:09 | Fix harmless compiler warnings in changebatch. (check-in: a721a73818 user: drh tags: changebatch) | |
| 17:30 | Fix an uninitialized variable in CASE expression code generation. (check-in: c8ffae05e1 user: drh tags: rowvalue) | |
| 17:02 | Add a new method to sessions - sqlite3sessions_fullchangeset() - to return a changeset that always contains values for all old.* fields. Update changebatch to use these values to more reliably detect multi-column UNIQUE constraint violations. (check-in: efa761b2f5 user: dan tags: changebatch) | |
| 14:42 | Fix the SQLITE_USER_AUTHENTICATION login check so that the SQLITE_AUTH_USER error code correctly propagates and is not overwritten by SQLITE_ERROR. (check-in: c640489db2 user: drh tags: trunk) | |
|
2016-08-22
| ||
| 21:01 | Add a couple of extra tests to changebatch1.test. (check-in: 207d970b79 user: dan tags: changebatch) | |
| 20:49 | Add an experimental module to detect conflicts between sessions changesets. (check-in: 0c9fd6b723 user: dan tags: changebatch) | |
| 20:10 | Add support for the SQLITE_DBCONFIG_MAINDBNAME configuration option. (check-in: 7839519349 user: drh tags: trunk) | |
| 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) | |

| 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) | |
| 21:02 | Clarification of code comments in expr.c. Clean up the implementations of sqlite3ExprIsVector() and sqlite3ExprVectorSize() slightly. (check-in: 4fb66d6592 user: drh tags: rowvalue) | |
| 18:06 | Fixes for problems following OOM errors. (check-in: 9041ee4a6f user: drh tags: rowvalue) | |
| 17:23 | Fix other minor problems with the fts5 snippet() function. (check-in: b56b2a85cf user: dan tags: fts5-snippet-bias) | |
| 17:00 | Do not duplicate the Expr.pLeft subtree of a TK_SELECT_COLUMN node. (check-in: 8384c77ebb user: drh tags: rowvalue) | |
| 15:01 | Fix a segfault that could occur if a query that used a vector comparison contained certain types of syntax errors. (check-in: 203f07c5e1 user: dan tags: rowvalue) | |
| 12:00 | Improvements to the vector comparison splitter in exprAnalyze(). (check-in: a3ffd283bc user: drh tags: rowvalue) | |
| 01:06 | Improvements to comments. No code changes. (check-in: 4165d20f64 user: drh tags: rowvalue) | |
| 00:51 | Add support for vector assignments in the SET clause of an UPDATE statement. (check-in: f320d47d6b user: drh tags: rowvalue) | |
| 00:07 | Change the way TK_SELECT_COLUMN is handled so that the subquery is only generated once even if part of the vector comparison is used for indexing and the other part is now. This change also is a pathway to vector assignment in UPDATE statements. (check-in: d8feea7dcd user: drh tags: rowvalue) | |

| 19:58 | Replace the magic number (-2) with its symbol XN_EXPR in the exprMightBeIndexed() routine. No logic changes. (check-in: d4a5af69cc user: drh tags: rowvalue) | |
| 19:12 | Improved comments on sqlite3CodeSubquery(). No changes to code. (check-in: acea4ee136 user: drh tags: rowvalue) | |
| 18:40 | Show the WhereTerm.iField value on debugging output, when it is non-zero. (check-in: 931c95358d user: drh tags: rowvalue) | |
| 18:37 | Register any built-in fts5 module before loading automatic extensions. This allows automatic extensions to register fts5 tokenizers and auxiliary functions. (check-in: b10e31dce8 user: dan tags: fts5-snippet-bias) | |
| 18:28 | Fix an obsolete comment on codeEqualityTerm(). No changes to code. (check-in: d07be5afb0 user: drh tags: rowvalue) | |
| 15:41 | Merge recent enhancements from trunk. (check-in: b17872363b user: drh tags: rowvalue) | |
| 15:17 | Merge the VACUUM attached database enhancement from trunk. (Closed-Leaf check-in: 12d5e38d26 user: drh tags: dbconfig_maindbname) | |
| 15:15 | Enhance the VACUUM command so that it can operate on an attached database. (check-in: 083f9e6270 user: drh tags: trunk) | |
| 15:12 | Disable row counting on queries run while doing a VACUUM. (Closed-Leaf check-in: ad35ef1162 user: drh tags: vacuum-attached-db) | |
| 14:25 | Have the fts5 snippet() function avoid favouring snippets that begin with sentences that do not contain search terms. Add an extra bias in favour of the first sentence in the document. (check-in: d8180af2ad user: dan tags: fts5-snippet-bias) | |
| 14:20 | Add the capability to VACUUM an attached database by specifying the schema name as an argument to the VACUUM command. Since version 2.0, VACUUM has accepted an argument which was silently ignored. Now it has meaning. (check-in: 29d63059b4 user: drh tags: vacuum-attached-db) | |
