Darwin is fully coherent this way (that’s basically what a Universal Buffer Cache guarantees.) Even if it weren’t, the incoherency would cause problems while making changes, i.e. _before_ the power-loss, not afterwards. Which is not what’s seen. —Jens _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
