| # This file implements regression tests for SQLite library. The |
| # focus of this file is testing the operation of the library in |
| # "PRAGMA journal_mode=WAL" mode. |
| # |
| # Specifically, it tests the case where a connection opens an empty |
| # file. Then, another connection opens the same file and initializes |
| # the connection as a WAL database. Following this, the first connection |
| # executes a "PRAGMA page_size = XXX" command to set its expected page |
| # size, and then queries the database. |
| # |
| # This is an unusual case, as normally SQLite is able to glean the page |
| # size from the database file as soon as it is opened (even before the |
| # first read transaction is executed), and the "PRAGMA page_size = XXX" |
| # is a no-op. |
