SQLite fixed obscure 16-year old bug that caused database corruption
https://www.theregister.com/database...utages/5287004

How likely is it that this is the cause of some of the long-standing reports of weird and unexplained database corruption on Kindles? Does Amazon do a similar aggressive checkpointing? Is the WAL used?

The single user implementation used by Kindle and Kobo ereaders is unlikely to have triggered the data race bug.

To quote the SQLite documentation on the bug ( https://sqlite.org/wal.html#the_wal_reset_bug:
Quote:
The bug only affects databases in WAL mode when there are two or more database connections open on the same file, in separate threads or processes, and when those two connections attempt to write or checkpoint at the same instant.
