| ||
| 15:01 | Fix a potential problem in the whereRangeScanEst() routine when STAT4 is active. The problem was introduced by recent enhancements. (check-in: 68e1b4de70 user: drh tags: trunk) | |
| 13:08 | Cause the command-line shell to return non-zero if the final SQL statement is incomplete. (check-in: 177fff3b98 user: drh tags: trunk) | |
| 12:56 | Merge all recent trunk changes. (check-in: abfef25472 user: drh tags: sessions) | |
|

| ||
| 19:35 | Change the balance_nonroot() routine to reduce the amount of memcpy work that takes place. This is a work in progress. (check-in: 29304499ea user: dan tags: defrag-opt) | |
| 15:08 | Allow FTS tokenizers to choose whether or not to consider the "*" character part of tokens or not. This restores the pre-[e21bf7a2ad] behaviour. Also fix a problem causing FTS to interpret tokens beginning with "*" characters as EOF. (check-in: 49dfee7cd1 user: dan tags: trunk) | |
| 14:10 | Add a test case for the memory leak fixed by the previous check-in. (check-in: bae36d5446 user: drh tags: trunk) | |

| 11:40 | Record the errno on fstat() failures. (check-in: 2a6a082001 user: drh tags: apple-osx) | |
| 11:27 | Merge the latest trunk enhancements into the apple-osx branch. (check-in: 6fc7207727 user: drh tags: apple-osx) | |
|
2014-10-08
| ||
| 19:33 | Remove an always-true branch in whereRangeScanEst(). Replace it with an assert(). (check-in: 42e48fd3a6 user: drh tags: trunk) | |
| 15:53 | Fix up test cases to account for the new SQLITE_LIMIT_WORKER_THREADS limit. (check-in: 6483d426c4 user: drh tags: trunk) | |

| 02:53 | Fix the STAT4 range scan estimates for DESC indexes. (check-in: e3fe840052 user: drh tags: trunk) | |
| 00:08 | More intuitive labels on ".wheretrace" output. (check-in: adcb3fed48 user: drh tags: trunk) | |
|
2014-10-07
| ||
| 23:02 | Make sure the sqlite3VdbeMemClearAndResize() routine is never called with a zero size parameter, since a size of zero could lead to either a memory leak or an assertion fault. (check-in: f672a380e2 user: drh tags: trunk) | |
| 20:09 | Fix the corruptI.test script so that it works with SQLITE_ENABLE_OVERSIZE_CELL_CHECK and with SQLITE_DEFAULT_AUTOVACUUM=1. (check-in: e405b9e4a9 user: drh tags: trunk) | |
| 16:59 | Restrict the scope of the valueToText() routine. (check-in: 13c962b33d user: drh tags: trunk) | |
| 15:46 | Enhance (and fix) the MEMTYPE tags associated with heap memory allocations when SQLITE_MEMDEBUG is used. (check-in: ca5b789e33 user: drh tags: trunk) | |
|
2014-10-06
| ||
| 18:33 | Remove unreachable branches in decodeIntArray() when compiling without STAT3 or STAT4. (check-in: 80e1baa5c2 user: drh tags: trunk) | |
| 14:37 | Improve the accuracy of the estimates used when searching an index for values not present in any stat4 samples. (check-in: 3aff9a9cac user: dan tags: trunk) | |
| 12:41 | Fix a harmless compiler warning inside an assert() in FTS4. (check-in: 418f3c9ad2 user: drh tags: trunk) | |
|
2014-10-04
| ||
| 19:31 | Tweaks to documentation on sqlite3_open() and sqlite3_bind(). No code changes. (check-in: b8f7f19dc0 user: drh tags: trunk) | |

| 10:22 | Add a test to show that the change on this branch is effective. (Closed-Leaf check-in: fc619be057 user: dan tags: stat4-avgeq) | |
| 00:07 | Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside. (check-in: efd87ba142 user: drh tags: stat4-avgeq) | |
|
2014-10-03
| ||

| 19:16 | Improve the accuracy of the estimates used when searching an index for values not present in any stat4 samples under some circumstances. (check-in: e6f7f97dbc user: dan tags: stat4-avgeq) | |
| 16:00 | Add requirements marks on the sqlite3_db_status() interface implementation. Fix a typo in the documentation. Fix the new sqlite3_result_text64() routine so that it works correctly with an encoding parameter of SQLITE_UTF16. (check-in: d2fc322728 user: drh tags: trunk) | |
| 14:54 | Update to requirements marks related to changes in the memory allocation interface and enhancement of the documentation regarding DEFAULT clauses in CREATE TABLE. (check-in: 440705b98a user: drh tags: trunk) | |
|
2014-10-02
| ||
| 21:52 | Avoid a NULL pointer deference when processing the IS operator if the right-hand side is an illegal "#ID" style variable. Fix for ticket [8c32a33a53092c85a15b] (check-in: ffe7573636 user: drh tags: trunk) | |
| 09:27 | Fix a segfault that could occur if an 'optimize' command was issued on an FTS table that contained at least one row but zero terms. (Leaf check-in: b21746ac11 user: dan tags: branch-3.7.14) | |

| 12:01 | Avoid ever writing before the start of an allocated buffer in the DIRECT_OVERFLOW_READ code. Fix for [e3a290961a6]. (check-in: c3c15d20c6 user: dan tags: trunk) | |
| 01:52 | Merge the latest enhancements from trunk. (check-in: 2695772c98 user: drh tags: sessions) | |

| ||
| 21:24 | Draw the TreeView debugging graphs using unicode box-drawing characters. (Closed-Leaf check-in: 0efc6859d1 user: drh tags: box-character-graph) | |
| 19:04 | Improvements to the new syntax-tree output routines: Omit the "END SELECT" mark and instead terminate the graph at the last item. Increase the maximum tree depth to 100. (check-in: 5ce05757aa user: drh tags: trunk) | |
| 17:31 | Enable the query planner to deal with WHERE clauses that have OR terms nested within AND terms that are nested within OR terms. Also remove an unused function declaration. (check-in: b6b289182f user: drh tags: trunk) | |
| 17:03 | Further enhancements to the "wheretrace" debugging output. (check-in: 670993eb81 user: drh tags: trunk) | |
| 14:14 | Enhanced debug output for OR-logic in the query loop optimizer. (check-in: 2e375eae47 user: drh tags: trunk) | |

| 12:33 | Remove the SQLITE_ENABLE_TREE_EXPLAIN compile-time option. Add alternative debugging display routines: sqlite3TreeViewExpr(), sqlite3TreeViewExprList(), and sqlite3TreeViewSelect(). (check-in: 4ff51325d6 user: drh tags: trunk) | |
|
2014-09-29
| ||
| 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) | |
|
2014-09-27
| ||
| 20:45 | Change the names of the stream interface APIs to be of the form "_strm" instead of "_str". In other words, added an "m" to the end, to try to make it clear that we are talking about a "stream" and not a "string. (check-in: 1f44bfdc23 user: drh tags: sessions) | |
| 19:51 | Merge recent trunk changes (performance enhancements) into the sessions branch. (check-in: 497367cb57 user: drh tags: sessions) | |
