2012-06-19ntdb: special accessor functions for read/write of an offset.Rusty Russell1-0/+23
We also split off the NTDB_CONVERT case (where the ntdb is of a different endian) into its own io function.

2012-06-19ntdb: inline oob checkRusty Russell1-1/+1
The simple "is it in range" check can be inline; complex cases can be handed through to the normal or transaction handler.

2012-06-19ntdb: allocator attribute.Rusty Russell1-27/+34
This is designed to allow us to make ntdb_context (and NTDB_DATA returned from ntdb_fetch) a talloc pointer. But it can also be used for any other alternate allocator. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-06-19ntdb: still prepare recovery area with NTDB_NOSYNC.Rusty Russell1-10/+8
NTDB_NOSYNC now just prevents the fsync/msync calls, which speeds testing while still providing full coverage. It also provides safety against processes dying during transaction commit (though obviously, not against the machine dying). Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-06-19ntdb: remove last block transactoin logic.Rusty Russell1-44/+1
Now our database is always a multiple of NTDB_PGSIZE, we can remove the special handling for the last block. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-06-19ntdb: make sure file is always a multiple of PAGESIZE (now NTDB_PGSIZE)Rusty Russell1-33/+33
ntdb uses tdb's transaction code, and it has an undocumented but implicit assumption: that the transaction recovery area is always aligned to the transaction pagesize. This means that no block will overlap the recovery area. This is maintained by rounding the size of the database up, so do the same for ntdb. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-06-19ntdb: fix recovery data write.Rusty Russell1-1/+2
We were missing the last few bytes. Found by 100 runs of ntdbtorture -t -k. The transaction test code didn't catch this, because usually those last few bytes are irrelevant to the actual contents of the database. We fix the test. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-06-19ntdb: remove ntdb_error()Rusty Russell1-41/+33
It was a hack to make compatibility easier. Since we're not doing that, it can go away: all callers must use the return value now. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
2012-06-19TDB2: Goodbye TDB2, Hello NTDB.Rusty Russell1-0/+1322
This renames everything from tdb2 to ntdb: importantly, we no longer use the tdb_ namespace, so you can link against both ntdb and tdb if you want to. This also enables building of standalone ntdb by the autobuild script. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
