2016-08-23
| ||
| 17:30 | Fix an uninitialized variable in CASE expression code generation. (check-in: c8ffae05 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: efa761b2 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: c640489d user: drh tags: trunk) | |
|
2016-08-22
| ||
| 21:01 | Add a couple of extra tests to changebatch1.test. (check-in: 207d970b user: dan tags: changebatch) | |
| 20:49 | Add an experimental module to detect conflicts between sessions changesets. (check-in: 0c9fd6b7 user: dan tags: changebatch) | |
| 20:10 | Add support for the SQLITE_DBCONFIG_MAINDBNAME configuration option. (check-in: 78395193 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: 07e69f43 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: 2f39987f 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: e50d264f user: drh tags: rowvalue) | |
| 21:11 | Further comment enhancements. No changes to code. (check-in: d4562a9e user: drh tags: rowvalue) | |
| 21:02 | Clarification of code comments in expr.c. Clean up the implementations of sqlite3ExprIsVector() and sqlite3ExprVectorSize() slightly. (check-in: 4fb66d65 user: drh tags: rowvalue) | |
| 18:06 | Fixes for problems following OOM errors. (check-in: 9041ee4a user: drh tags: rowvalue) | |
| 17:23 | Fix other minor problems with the fts5 snippet() function. (check-in: b56b2a85 user: dan tags: fts5-snippet-bias) | |
| 17:00 | Do not duplicate the Expr.pLeft subtree of a TK_SELECT_COLUMN node. (check-in: 8384c77e 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: 203f07c5 user: dan tags: rowvalue) | |
| 12:00 | Improvements to the vector comparison splitter in exprAnalyze(). (check-in: a3ffd283 user: drh tags: rowvalue) | |
| 01:06 | Improvements to comments. No code changes. (check-in: 4165d20f user: drh tags: rowvalue) | |
| 00:51 | Add support for vector assignments in the SET clause of an UPDATE statement. (check-in: f320d47d 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: d8feea7d user: drh tags: rowvalue) | |
|
2016-08-19
| ||
| 19:58 | Replace the magic number (-2) with its symbol XN_EXPR in the exprMightBeIndexed() routine. No logic changes. (check-in: d4a5af69 user: drh tags: rowvalue) | |

| 15:12 | Disable row counting on queries run while doing a VACUUM. (Closed-Leaf check-in: ad35ef11 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: d8180af2 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: 29d63059 user: drh tags: vacuum-attached-db) | |
|
2016-08-18
| ||
| 22:44 | Add the SQLITE_DBCONFIG_MAINDBNAME interface. (check-in: d6e3d579 user: drh tags: dbconfig_maindbname) | |

| 20:56 | Fix a zName to zDbSName conversion missed in the previous check-in. (Closed-Leaf check-in: d7cf423c user: drh tags: zDbSName) | |
| 19:04 | Fix a SQL NULL handling bug in the vector IN operator code generation. (check-in: 936146b1 user: drh tags: rowvalue) | |
| 18:09 | Display SELECT_COLUMN expressions in the .wheretrace debugging output. (check-in: 3b27a5da user: drh tags: rowvalue) | |
| 17:55 | Display VECTOR expressions in .wheretrace and .selecttrace debugging output. (check-in: 157347e2 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: b40b202c user: drh tags: rowvalue) | |
| 15:21 | Merge recent enhancements from trunk. (check-in: 4768a106 user: drh tags: rowvalue) | |
| 15:15 | Simplify the vector comparison code generator logic, and the resulting VDBE code. (check-in: e2ad0b5d user: drh tags: rowvalue) | |
| 14:47 | Adjust some tests to account for recent changes to the fts5 snippet function. (check-in: 184ecbe9 user: dan tags: fts5-snippet-bias) | |
| 14:33 | Rename the Db.zName field to Db.zDbSName to make it more descriptive and to distinguish it from all of the other "zName" variables scattered throughout the code. (check-in: 92a22f01 user: drh tags: zDbSName) | |
|
2016-08-17
| ||
| 19:05 | Bias the fts5 snippet() function to return snippets that look like they start at the start of sentences. (check-in: 60de1594 user: dan tags: fts5-snippet-bias) | |
| 11:14 | Fix a problem in the fts5 snippet() auxiliary function. (check-in: a861713c user: dan tags: trunk) | |
|
2016-08-16
| ||
| 16:46 | Fix a bug in destructor processing of Lemon. That has no impact on the SQLite grammar. The bug was introduced by prior work to optimize the Lemon-generated parser used by SQLite. (check-in: f9035b8e user: drh tags: trunk) | |
|
2016-08-13
| ||
| 14:30 | Questionable changes to support interruptible checkpoint in ZipVFS. (Leaf check-in: c7a9f26d user: dan tags: interruptible-checkpoint) | |

| 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: dfc028cf user: drh tags: vector-compare) | |
| 06:38 | Fix a buffer overread in fts5. (check-in: fcfbee6c user: dan tags: trunk) | |
|
2016-08-12
| ||

| 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: 25d1d02b user: drh tags: trunk) | |
| 13:34 | Increment the version number to 3.15. (check-in: 8c2701e7 user: drh tags: trunk) | |
| 13:30 | Improved comments on the lempar.c parser template. Adjust the YY_SHIFT_USE_DFLT constant in the Lemon-generated parser tables so as to guarantee that it is always out of range of the yy_lookahead[] table. (check-in: 83622f3f user: drh tags: trunk) | |
| 11:50 | Fix pcache1TruncateUnsafe() run faster for the case where iLimit is very close to iMaxKey. (check-in: b07a26df user: drh tags: trunk) | |

| 14:08 | Add extra logging calls to this branch. (check-in: 491f1ef3 user: dan tags: debug) | |
| 13:39 | Merge all recent enhancements from trunk. (check-in: dacfff51 user: drh tags: apple-osx) | |
| 13:23 | Revert the SQLITE_APICALL changes for now. That changes needs further research before it is released. Deferred until 3.15. (check-in: 9adda385 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: b7f30a9f user: drh tags: trunk) | |
