| 6 | Make sure that the pagesize passed to db__set_pagesize() is a power of two. | |

| 8 | nvi stores the content of files in BDB database structures. When initiating a | |
| 9 | file, it picks a page size for the database to fit the file within 15 pages, | |
| 10 | with a minimal page size of 1K and maximal of 10K. | |
| 11 | ||
| 12 | In vanilla nvi, this size is calculated as a multiple of 1024. Modern versions | |
| 13 | of BDB, however, require the page size of a database to be a power of two, which | |
| 14 | this patch addresses, ridding us of the following message: | |
| 15 | ||
| 16 | BDB0511 page sizes must be a power-of-2 | |
