2016-08-22
| ||
| 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) | |
|
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) | |
| 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) | |

| 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) | |
|
2016-08-19
| ||
| 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) | |

| 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) | |

| 15:12 | 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) | |
|
2016-08-18
| ||

| 19:04 | Fix a SQL NULL handling bug in the vector IN operator code generation. (check-in: 936146b12e user: drh tags: rowvalue) | |
| 18:09 | Display SELECT_COLUMN expressions in the .wheretrace debugging output. (check-in: 3b27a5da10 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) | |

| 14:47 | Adjust some tests to account for recent changes to the fts5 snippet function. (check-in: 184ecbe9c0 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: 92a22f0134 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: 60de159476 user: dan tags: fts5-snippet-bias) | |
| 11:14 | Fix a problem in the fts5 snippet() auxiliary function. (check-in: a861713cc6 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: f9035b8e2e user: drh tags: trunk) | |
|
2016-08-13

| 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) | |
| 06:38 | Fix a buffer overread in fts5. (check-in: fcfbee6c7d user: dan tags: trunk) | |

| 11:25 | Add VdbeCoverage() macros on newly added VDBE branch operations. (check-in: 381aa73141 user: drh tags: rowvalue) | |
| 11:01 | Fix a post-OOM memory leak. (check-in: 14009b32b9 user: drh tags: rowvalue) | |

| 18:05 | Add the "modeof=<filename>" URI parameter to os_unix.c - used to specify a file to copy permissions from when a new database is created. Also allow passing NULL as the second parameter to sqlite3rbu_vacuum(). (check-in: ed406d31ff user: dan tags: trunk) | |
| 13:51 | Fix a 1 byte buffer overwrite in the "sqldiff --rbu" command. (check-in: 1adb22f51a user: drh tags: branch-3.14) | |

| 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) | |
