| 20:04 | When a table is renamed using "ALTER TABLE RENAME TO", update any REFERENCES clauses that refer to the table, unless "PRAGMA legacy_alter_table" is true and "PRAGMA foreign_keys" is set to false (i.e. so that when "PRAGMA legacy_alter_table" is set behaviour is still compatible with versions 3.24 and earlier). file: [61c1ace4] check-in: [ae9638e9] user: dan branch: trunk, size: 52155 | |

|
2018-09-20
| ||
| 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. file: [65fc93f6] check-in: [7edd26ed] user: drh branch: trunk, size: 51893 | |
| 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. file: [e561794b] check-in: [ad130bb8] user: drh branch: trunk, size: 51539 | |

|
2018-09-19
| ||
| 20:14 | Reduce the size of Expr to 64-bytes. This works somewhat, but there are test failures. More importantly, the size reduction from 80- to 64-bytes has not lowered the schema memory usage, but it has made the code a little bigger and a little slower. So the initial evidence is that this Expr refactoring experiment is not working... file: [3a859149] check-in: [24b0f66a] user: drh branch: expr-simplify, size: 51609 | |
