If a single page is written to the wal file more than once, instead of appending the second and subsequent copy to the wal file, overwrite the first. Update: See the important bug fix at [f694e60a]! check-in: d493d4f118 user: dan tags: trunk

All WAL frame overwrites even if there are active savepoints. This is safe because a ROLLBACK TO will cause all reverted pages to be rewritten to the WAL file prior to COMMIT. check-in: 99b31a6b49 user: drh tags: wal-overwrite-frames

If it is known that checksums will be recalculated on transaction commit, skip calculating checksums when appending frames to the wal file. When recalculating checksums, recalculate them starting with the first overwritten frame - not the first frame in the transaction. check-in: 16b34f2537 user: dan tags: wal-overwrite-frames

If a single page is written to the wal file more than once, have each subsequent copy overwrite the original frame. check-in: 5d113aef2c user: dan tags: wal-overwrite-frames
