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: f672a380 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: e405b9e4 user: drh tags: trunk

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

2014-09-30
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

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
2014-09-29
15:42
Fix the header comment in sqlite3VdbeDeletePriorOpcode(). No changes to code. check-in: 7fb16268 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: 414f0d6a user: drh tags: trunk
2014-09-26

Add an assert() to verify the last-row-id for the database just prior to calling a SQL function. check-in: d026f0c9 user: mistachkin tags: trunk
02:41
Fix the "PRAGMA integrity_check" command so that it avoids formatting error message context messages until it actually needs to generate an error message. This avoids much formatting, and hence greatly improves the performance of "PRAGMA integrity_check" in the common case when there are no errors. It also makes the code a little smaller. check-in: 83913515 user: drh tags: trunk
01:10
If an SQL function makes a recursive call to do an INSERT into the same database, make sure that the last_insert_rowid() for that INSERT is recorded. check-in: e93aecc0 user: drh tags: trunk

Simplification to the random rowid picking logic that begins running when the maximum possible rowid has already been used. check-in: 1330c72e user: drh tags: trunk
11:08
Still more performance enhancements to the LIKE and GLOB operators. check-in: 6c8924ca user: drh tags: trunk

Do not allow parameters in a DEFAULT clause of a CREATE TABLE statement. Ticket [78c0c8c3c9f7c1]. check-in: 1ad2bc1e user: drh tags: trunk
02:05
Have the clearCell() routine return the cell size to the caller, rather than have the caller make a separate call to cellSizePtr(). check-in: f21d2175 user: drh tags: trunk

Add the MemPage.noPayload boolean and use it to help cellSizePtr() and btreeParseCellPtr() run faster. check-in: 8e337531 user: drh tags: trunk
2014-09-23
23:12
Remove an unused C-preprocessor macro. No functional changes to the code. check-in: f480582c user: drh tags: trunk
22:36
Avoid calling btreeParseCellPtr() from within fillInCell() since most of what btreeParseCellPtr() computes is ignored by fillInCell(). Instead, have fillInCell() compute the values it needs inline. Performance improvement. check-in: 4147f667 user: drh tags: trunk
21:25
Simplify the CellInfo structure for a size reduction and performance improvement. check-in: bf59df66 user: drh tags: trunk
18:30
Add the "multiplex_truncate" PRAGMA to the multiplexor extension, for querying and setting the truncate flag on a database connection. check-in: d2962a5f user: drh tags: trunk
