18dbpagesize_binpower.dpatch by <hesso@pool.math.tu-berlin.de>
|

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

|

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