| 12:37 | Use compile-time options SQLITE_QUERY_PLANNER_LIMIT and SQLITE_QUERY_PLANNER_LIMIT_INCR to control the value for WhereLoopBuilder.iPlanLimit, rather than embedding magic numbers in the code. check-in: 903e5018 user: drh tags: trunk | |
| 10:47 | Increase the initial value of WhereLoopBuilder.iPlanLimit to 20K. Issue a warning if the iPlanLimit reaches zero. check-in: 3dd35f51 user: drh tags: trunk | |
|
2018-09-23

2018-09-21
| ||
| 23:41 | Fix harmless compiler warning when compiled with SQLITE_OMIT_AUTHORIZATION. check-in: 50f2fa19 user: mistachkin tags: trunk | |
| 19:06 | Comment typo fixed. No code changes. check-in: 7e68cdab user: drh tags: trunk | |
| 18:43 | Put a limit counter on the query planner that restricts the number of index+constraint options that can be considered for each table in a join. This prevents certain pathological queries from taking up too much time in the query planner. check-in: 8690b5a0 user: drh tags: trunk | |
| 13:07 | Optimization to the OP_MakeRecord opcode makes speed-check.sh run about 1.1 million cycles faster, and results in a slightly smaller library. check-in: d10e6362 user: drh tags: trunk | |

| ||
| 20:43 | Minor code simplification. check-in: 22ae8a52 user: drh tags: trunk | |
| 20:15 | Add the "PRAGMA legacy_alter_table=ON" command to enable the pre-3.25.0 behavior of ALTER TABLE that does not modify the bodies of triggers or views or the WHERE clause of a partial index. Enable the legacy behavior by default when running the xRename method of virtual tables. check-in: 7edd26ed user: drh tags: trunk | |
| 19:02 | Combine the Expr.pTab and Expr.pWin fields into a union named "y". Add a new EP_WinFunc property that is only true if Expr.y.pWin is a valid pointer. This reduces the size of the Expr object by 8 bytes, reduces the overall amount of code, and shaves over 1 million cycles off of the speed test. check-in: ad130bb8 user: drh tags: trunk | |
| 17:21 | By default, make all "ALTER TABLE RENAME" statements executed within a virtual table xRename() method exhibit the legacy behaviour. Closed-Leaf check-in: 71947337 user: dan tags: legacy-alter-table | |
| 08:28 | Add a PRAGMA that restores the legacy ALTER TABLE RENAME TO behaviour. check-in: 5acad2e9 user: dan tags: legacy-alter-table | |

| 19:40 | Fix a problem building on Android with SQLITE_ENABLE_BATCH_ATOMIC_WRITE set. check-in: e41e50fe user: dan tags: trunk | |

| 17:00 | Enhance tester.tcl so that when "--malloctrace=1" is specified, the test generates self-contained Tcl scripts that present GUIs instead of *.sql files that require a separate program to interpret. check-in: de2e3cbd user: dan tags: trunk | |
| 16:06 | Minor improvements to the permutations.test script. Most notably, a command like "permutations.test alter%" now runs all test scripts with names that match the LIKE pattern "alter%". Or, say, "permutations wal alter%" to run all alter% tests in wal mode. check-in: 3e1a2f66 user: dan tags: trunk | |

This changes is a fix for the follow-in tocket [510cde277783b5fb5de628]. check-in: c6c9585f user: drh tags: trunk | |
| 14:13 | Fix a false-positive in the post-ALTER-TABLE schema verification logic that prevents ALTER TABLE from working if the table being altered has a trigger that references any column of a virtual table. Ticket [b41031ea2b537237]. check-in: 84105ea4 user: drh tags: trunk | |
| 13:55 | Restore an assert() that was present on trunk. Closed-Leaf check-in: a7b572ca user: drh tags: tkt-b41031ea | |

| 15:01 | Improved presentation on the new code that prevents unnecessary writes to expressions on indexes during an UPDATE when the expression does not reference any of the columns that are changing. check-in: c9f04529 user: drh tags: trunk | |
