commit 7c6713e78ff22ebf0aa1caa10697bad9d4cc885e
Author: Rusty Russell <rusty at rustcorp.com.au>
Date:   Mon Jan 30 15:59:18 2012 +1030

    tdb2: make --enable-tdb2 the default.
    
    We still use the tdb1 on-disk format, but we do so via the tdb2 library.

    tdb2: add -1 and -2 options to tdbtorture
    
    (For now, -1 is the default).

    tdb2: name tools the same as TDB1 tools.
    
    Otherwise, when we switch everyone's scripts will break (including our
    own tests!).

commit 641beb35bff243bab5651a1cab8aa4b305ecefa4
Author: Rusty Russell <rusty at rustcorp.com.au>
Date:   Mon Jan 30 10:07:17 2012 +1030

    samdb: use compat wrappers for tdb_fetch().
    
    TDB2's tdb_fetch() returns an error code; use tdb_fetch_compat() for now.
    Similarly, tdb_errorstr() -> tdb_errorstr_compat().

    tdb_compat: only use hashsize attribute when O_CREAT
    
    tdb2 complains if you specify a tdb1 hashsize, and you're not actually
    trying to create a new database.

commit ae62d46a9fcfee9db177ddb3d0f1f2c28c889a35
Author: Rusty Russell <rusty at rustcorp.com.au>
Date:   Mon Jan 30 09:25:50 2012 +1030

    ldb_wrap.c: fix TDB2-incompatible API usage.
    
    Auditing revealed one place still expecting a -1 return on failure:
    tdb2 returns the (negative) errcode directly, so the portable way to
    do this is to check for != 0.

commit efbf52b4fe62eeed085961d7e2689b869bae63dc

    tdb2: copy tdb1's changed expansion logic.
    
    TDB2 uses the same expansion logic as TDB1, which got factored out
    recently.  So update TDB2 to match.

commit 205e198471a481b849d05b5756261f1739c0c8b2
Author: Rusty Russell <rusty at rustcorp.com.au>
Date:   Mon Jan 30 09:23:50 2012 +1030

    tdb2: careful on wrap.
    
    It's much harder to wrap a 64-bit tdb2 than a 32-bit tdb1, but we should still
    take care against bugs.
    
    Also, we should *not* cast the length to a size_t when comparing it to
    the stat result, in case size_t is 32 bit.
