<p>This change only affects Win/32 applications that create in-memory
|
|||
|
|
databases.</p>
|
|||
|
|
<p>On Win/32 platforms an additional test has been added when searching for
|
|||
|
|
the appropriate directory in which to create the temporary files that are
|
|||
|
|
used to back in-memory databases. Berkeley DB now uses any return value from
|
|||
|
|
the GetTempPath interface as the temporary file directory name before
|
|||
|
|
resorting to the static list of compiled-in pathnames.</p>
|
|||
|
|
<p>If the system registry does not return the same directory as Berkeley DB has
|
|||
|
|
been using previously, this change could cause temporary backing files to
|
|||
|
|
move to a new directory when applications are upgraded to the 3.1 release.
|
|||
|
|
In extreme cases, this could create (or fix) security problems if the file
|
|||
|
|
protection modes for the system registry directory are different from
|
|||
|
|
those on the directory previously used by Berkeley DB.</p>
