2013-02-20ntdb: switch between secrets.tdb and secrets.ntdb depending on 'use ntdb'Rusty Russell1-0/+5
Since we open with dbwrap, it auto-converts old tdbs (which it will rename to secrets.tdb.bak once it's done).

2013-02-20tdb_wrap: prevent tdbs called ".ntdb" or without extensions.Rusty Russell1-0/+8
This is another belt-and-braces check in case someone decides to turn on the fancy new .ntdb extension, and we haven't converted it to ntdb. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Reviewed-by: Andrew Bartlett <abartlet@samba.org>
2013-02-20dbwrap_local_open: never open the .tdb if there is an .ntdbRusty Russell1-0/+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>
2013-02-20dbwrap_local_open: open NTDB if extension is .ntdbRusty Russell1-5/+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. Downgrade would be manual, eg: ntdbdump foo.ntdb | tdbrestore foo.tdb && mv foo.ntdb foo.ntdb.bak Signed-off-by: Rusty Russell <rusty@rustcorp.com.au> Reviewed-by: Andrew Bartlett <abartlet@samba.org>

2013-02-20ntdb: fix database corruption when transaction doesn't change anything.Rusty Russell3-15/+91
ntdb's transaction code has an optimization which tdb's doesnt: it only writes the parts of blocks whose contents have changed. This means we can actually have a transaction which turns out to need no recovery region. This breaks the recovery setup logic, which sets the current recovery size to 0 if there's no recovery area, and assumes that we'll always create a new recovery area since the recovery will always need > 0 bytes. In fact, if we really haven't changed anything, we can skip the transaction commit altogether: since this happens at least once with Samba, it's worth doing.

realloc(NULL, ...) is equivalent to malloc. We are already using this realloc property for tdb->lockrecs. It should not make any difference in speed, it just makes for a little simpler code.

For the mutex code we will have to lock the hashchain and the record lock area independently. So we will have to call the loop twice. And, it's a small refactoring for the better anyway I think. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>

2013-02-19tdb: Enhance lock tracking a bitVolker Lendecke1-0/+11
lock-tracking.c mirrors the in-kernel fcntl structures to detect unexpected use of fcntl calls. During my mutex work I changed our fcntl use so that we unlock the allrecord_lock in two pieces: The range covering the hash locks and the range covering the data area for the individual traverse record locks. Splitting locks is not covered by lock-tracking.c. This patch extends lock-tracking.c with this little piece. It's still far from complete to track the full range of fcntl semantics. It is not strictly needed right now, but it does not hurt either. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Stefan Metzmacher <metze@samba.org>
