Berkeley DB

Windows Notes

• Various Berkeley DB interfaces take a mode argument, which is intended to specify the underlying file permissions for created files. Berkeley DB currently ignores this argument on Windows systems.

  It would be possible to construct a set of security attributes to pass to CreateFile that accurately represents the mode. In the worst case, this would involve looking up user and all group names, and creating an entry for each. Alternatively, we could call the _chmod (partial emulation) function after file creation, although this leaves us with an obvious race.

  Practically speaking, however, these efforts would be largely meaningless on FAT, the most common filesystem, which only has a “readable” and “writeable” flag, applying to all users. ...
