01:18
[fa2c3be9] part of check-in [230556e8] The ALTER TABLE fix of check-in [7e5ad8e0ab7ee91a] is no longer needed due to the changes at check-in [4cf8721f5ceb1fda]. But, we keep the defense in place as an assert() for extra safety. (check-in: [230556e8] user: drh branch: trunk, size: 55439)

(check-in: [ae9638e9] user: dan branch: trunk, size: 52155)
2018-10-08
18:58
[59fa3409] part of check-in [2ac72114] Merge latest trunk changes into this branch. (check-in: [2ac72114] user: dan branch: reuse-schema, size: 52124)

2018-09-20
20:15
[65fc93f6] part of check-in [7edd26ed] 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 branch: trunk, size: 51893)
19:02
[e561794b] part of check-in [ad130bb8] 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 branch: trunk, size: 51539)

2018-09-19
20:14
[3a859149] part of check-in [24b0f66a] 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... (check-in: [24b0f66a] user: drh branch: expr-simplify, size: 51609)
2018-09-17
13:38
[2269dd2f] part of check-in [4d8be404] Minor modification to the fix on this branch to avoid adding extra conditional compilation macros. (check-in: [4d8be404] user: dan branch: tkt-b41031ea, size: 51533)
