| 13:31 | Bring the sessions branch up-to-date with all the latest trunk changes. (check-in: 086a127236 user: drh tags: sessions) | |
| 13:22 | Add the SQLITE_STMTSTATUS_VM_STEPS option for sqlite3_stmt_status(). (check-in: bd4267f17b user: drh tags: trunk) | |
| 11:49 | Omit tables from the FROM clause of a join if their presence makes no difference in the final output. (check-in: 6505e2ab02 user: drh tags: trunk) | |

| 02:15 | Only eliminate inner loops of a JOIN if they are the RHS of a LEFT JOIN and if they give no more than a single result. This appears to give correct answers in all cases. (check-in: d7a25cc797 user: drh tags: omit-join-table-opt) | |
| 02:05 | Attempt to disable inner loops of a join that do not generate output. This does not work, since the inner loops might run zero times and thus inhibit all output.

|
2013-06-13

| 17:58 | An index might be useful for ORDER BY if any indexed column is in the ORDER BY clause, not just the first indexed column. (check-in: ade473b5ae user: drh tags: nextgen-query-plan-exp) | |
| 17:28 | Make sure that disabling the covering index scan optimization does not prevent a covering index from being used to satisfy an ORDER BY clause. (check-in: e8b7ea8202 user: drh tags: nextgen-query-plan-exp) | |

| 20:16 | Remove a stray tab character from the transitive_closure extension source code. (check-in: 7a9aa21c35 user: drh tags: trunk) | |
| 17:15 | Fix a bug in SQLITE_TRACE_SIZE_LIMIT that was introduced by check-in [1a1cf5aa86734c8]. That check-in was to remove harmless compiler warnings. So once again, we have introduced a real bug into SQLite by attempting to eliminate a harmless compiler warning. (check-in: cec2bcb45a user: drh tags: trunk) | |
| 16:41 | In test file test_syscall.c, include sqliteInt.h before any tcl or system include files. This ensures that the magical defines in sqliteInt.h really do enable large file support (and set things up so that sizeof(off_t)==8). (check-in: 0f355bb17f user: dan tags: trunk) | |
| 12:52 | Use sum() instead of total() in mptest/multiwrite01.test too. (check-in: d0c2288c72 user: drh tags: trunk) | |

| 12:25 | Add extra "PRAGMA mmap_size = N" statements to mmap1.test and mmap2.test. (check-in: cec0a06c17 user: dan tags: trunk) | |
| 12:10 | In os_unix.c and os_win.c, initialize the default mmap-limit of a new file descriptor to the current global default mmap-limit, not the current global maximum allowable mmap-limit. (check-in: 1def4ea3a0 user: dan tags: trunk) | |

| 12:41 | Fix compilation with SQLITE_OMIT_WAL on Win32. (check-in: 6d45a79fb1 user: mistachkin tags: trunk) | |
| 11:57 | In sqlite3_close_v2(), do not attempt to roll back a transaction if there exist active statement objects. Any open transaction will be rolled back when the last of these statement objects is finalized. (check-in: d11e76072a user: dan tags: trunk) | |
| 01:02 | Treat identifiers in the HAVING clause the same as in the WHERE clause. Only consider AS names from the result set to match if there are no other matches. Continuation of the fix for [2500cdb9be05]. This check-in fixes a bug found by SqlLogicTest during release testing for version 3.7.17. (check-in: 9ffff3d052 user: drh tags: trunk) | |

| 18:34 | Fixes to allow testfixture to be compiled with SQLITE_OMIT_VIRTUAL_TABLE defined. (check-in: 00231fb012 user: dan tags: trunk) | |
| 17:47 | The sqlite3ExprCollSeq() function can no longer be called while parse the schema, so remove the code path inside of sqlite3ExprCollSeq() that dealt with that case. (check-in: 867b3e3b29 user: drh tags: trunk) | |
| 17:08 | Make sure an sqlite3_close() or a rollback on one shared-cache connection does not disrupt the operation of other connections using the same shared cache. Fix for ticket [e636a050b709]. (check-in: 5cc1cc55d2 user: drh tags: trunk) | |
| 16:24 | Extra test for commit [6dae62c4e5]. (check-in: b10b9e758b user: dan tags: trunk) | |

| 15:16 | When loading a database schema that contains an index definition that includes a COLLATE clause for which the collation sequence is unavailable, do not assume that that index uses BINARY instead. Fix for [0fc59f908b]. (check-in: 6dae62c4e5 user: dan tags: trunk) | |
| 13:05 | Add the rot13.c loadable extension. (check-in: 8f9bd8e7a8 user: drh tags: trunk) | |
| 10:21 | When closing a connection, avoid tripping active cursors belonging to a different shared-cache client. Also, if sqlite3_close() is called while there are still active statements belonging to the connection, return SQLITE_BUSY and do not roll back any active transaction. Proposed fix for ticket [e636a050b709]. (check-in: 6071b7cce0 user: dan tags: shared-cache-fixes) | |
