just involves splitting up the core tdb.c code into separate files on logical boundaries, but there are some minor functional changes as well: - move the 'struct tdb_context' into tdb_private.h, hiding it from users. This was done to allow the structure to change without breaking code that uses tdb. - added accessor functions tdb_fd(), tdb_name(), and tdb_log_fn() to access the elements of struct tdb_context that were used by external code but are no longer visible - simplied tdb_append() to use tdb_fetch()/tdb_store(), which is just as good due to the way tdb locks work - changed some of the types (such as tdb_off to tdb_off_t) to make syntax highlighting work better - removed the old optional spinlock code. It was a bad idea. - fixed a bug in tdb_reopen_all() that caused tdbtorture to sometimes fail or report nasty looking errors. This is the only real bug fixed in this commit. Jeremy/Jerry, you might like to pickup this change for Samba3, as that could definately affect smbd in Samba3. The aim of all of these changes is to make the tdb transactions/journaling code I am working on easier to write. I started to write it on top of the existing tdb.c code and it got very messy. Splitting up the code makes it much easier to follow. There are more cleanups we could do in tdb, such as using uint32_t instead of u32 (suggested by metze). I'll leave those for another day.
