16 check-ins using file src/main.c version 4a507a46

2014-10-04
10:22
Add a test to show that the change on this branch is effective. (Closed-Leaf check-in: fc619be0 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: efd87ba1 user: drh tags: stat4-avgeq)
2014-10-03
19:29
Fix a division-by-zero error that might occur if the sqlite_stat1 table is corrupt. (check-in: f9c053b2 user: dan tags: stat4-avgeq)
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: e6f7f97d 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: d2fc3227 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: 440705b9 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: ffe75736 user: drh tags: trunk)
2014-10-01
13:17
Show the TK_DOT operator in the TreeView debugging output. No changes to production code. (check-in: 07c89940 user: drh tags: trunk)
12:01
Avoid ever writing before the start of an allocated buffer in the DIRECT_OVERFLOW_READ code. Fix for [e3a290961a6]. (check-in: c3c15d20 user: dan tags: trunk)
2014-09-30
21:24
Draw the TreeView debugging graphs using unicode box-drawing characters. (Closed-Leaf check-in: 0efc6859 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: 5ce05757 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: b6b28918 user: drh tags: trunk)
17:03
Further enhancements to the "wheretrace" debugging output. (check-in: 670993eb user: drh tags: trunk)
14:14
Enhanced debug output for OR-logic in the query loop optimizer. (check-in: 2e375eae user: drh tags: trunk)
13:46
Show tree diagrams of data structures in the debugging output when the 0x100 bit is set on sqlite3WhereTrace or sqlite3SelectTrace. (check-in: 92e0b4bd 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: 4ff51325 user: drh tags: trunk)
