* dbwrap: completely check validity of lock order in dbwrap_check_lock_order()Michael Adam2014-02-071-1/+1
| | | | | | | | | | | This is currently not strictly necessay, because the only caller catches the DBWRAP_LOCK_ORDER_NONE case, and maximum is already checked, but this seems too dangerous to me.

* dbwrap_local_open: never open the .tdb if there is an .ntdbRusty Russell2013-02-201-0/+5
| | | | | | | | | This provides an extra safety check that everyone is using one or the other: you can't create a tdb file if there's an ntdb file. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Reviewed-by: Andrew Bartlett <abartlet@samba.org>
* dbwrap_local_open: open NTDB if extension is .ntdbRusty Russell2013-02-201-5/+157
| | | | | | | | | | | | | | | | | | | | | | This switches dbwrap_local_open() based on the extension of the database name, so it handles both TDB and NTDB files. Moreover, if asked to open a .ntdb, and there's no ntdb file but there's a .tdb file, it converts that then moves it to .tdb.bak before opening, and turn the .tdb file into a dangling symlink to make sure it's never accidentally re-created or used: $ ls -l secrets.tdb lrwxrwxrwx 1 rusty rusty 23 Feb 11 11:31 secrets.tdb -> This is now in an NTDB This provides transparent upgrade if people decide to use NTDB on a database.
