This makes + using the transaction API simpler, as otherwise the caller would + have to cope with temporary failures in transactions that conflict + with other current transactions + + - keep the transaction recovery information in the same file as the + database, using a special 'transaction recovery' record pointed at + by the header. This removes the need for extra journal files as + used by some other databases + + - dynamically allocated the transaction recover record, re-using it + for subsequent transactions. If a larger record is needed then + tdb_free() the old record to place it on the normal tdb freelist + before allocating the new record + + - during transactions, keep a linked list of writes all that have + been performed by intercepting all tdb_write() calls. The hooked + transaction versions of tdb_read() and tdb_write() check this + linked list and try to use the elements of the list in preference + to the real database. + + - don't allow any locks to be held when a transaction starts, + otherwise we can end up with deadlock (plus lack of lock nesting + in posix locks would mean the lock is lost) + + - if the caller gains a lock during the transaction but doesn't + release it then fail the commit + + - allow for nested calls to tdb_transaction_start(), re-using the + existing transaction record. If the inner transaction is cancelled + then a subsequent commit will fail + + - keep a mirrored copy of the tdb hash chain heads to allow for the + fast hash heads scan on traverse, updating the mirrored copy in + the transaction version of tdb_write + + - allow callers to mix transaction and non-transaction use of tdb, + although once a transaction is started then an exclusive lock is + gained until the transaction is committed or cancelled + + - the commit stategy involves first saving away all modified data + into a linearised buffer in the transaction recovery area, then + marking the transaction recovery area with a magic value to + indicate a valid recovery record. In total 4 fsync/msync calls are + needed per commit to prevent race conditions. It might be possible + to reduce this to 3 or even 2 with some more work. + + - check for a valid recovery record on open of the tdb, while the + global lock is held. Automatically recover from the transaction + recovery area if needed, then continue with the open as + usual. This allows for smooth crash recovery with no administrator + intervention. + + - if TDB_NOSYNC is passed to flags in tdb_open then transactions are + still available, but no transaction recovery area is used and no + fsync/msync calls are made. + +*/ + + +/* + hold the context of any current transaction +*/ +struct tdb_transaction { + /* we keep a mirrored copy of the tdb hash heads here so + tdb_next_hash_chain() can operate efficiently */ + uint32_t *hash_heads; + + /* the original io methods - used to do IOs to the real db */ + const struct tdb_methods *io_methods; + + /* the list of transaction blocks.

It was inspired by the realisation that +in Samba we have several ad-hoc bits of code that essentially +implement small databases for sharing structures between parts of +Samba. As I was about to add another I realised that a generic +database module was called for to replace all the ad-hoc bits. + +I based the interface on gdbm. I couldn't use gdbm as we need to be +able to have multiple writers to the databases at one time. + +Compilation +----------- + +add HAVE_MMAP=1 to use mmap instead of read/write +add NOLOCK=1 to disable locking code + +Testing +------- + +Compile tdbtest.c and link with gdbm for testing. tdbtest will perform +identical operations via tdb and gdbm then make sure the result is the +same + +Also included is tdbtool, which allows simple database manipulation +on the commandline. + +tdbtest and tdbtool are not built as part of Samba, but are included +for completeness. + +Interface +--------- + +The interface is very similar to gdbm except for the following: + +- different open interface. The tdb_open call is more similar to a + traditional open() +- no tdbm_reorganise() function +- no tdbm_sync() function. No operations are cached in the library anyway +- added a tdb_traverse() function for traversing the whole database +- added transactions support + +A general rule for using tdb is that the caller frees any returned +TDB_DATA structures. Just call free(p.dptr) to free a TDB_DATA +return value called p. This is the same as gdbm. + +here is a full list of tdb functions with brief descriptions. + + +---------------------------------------------------------------------- +TDB_CONTEXT *tdb_open(char *name, int hash_size, int tdb_flags, + int open_flags, mode_t mode) + + open the database, creating it if necessary + + The open_flags and mode are passed straight to the open call on the database + file. A flags value of O_WRONLY is invalid + + The hash size is advisory, use zero for a default value. + + return is NULL on error + + possible tdb_flags are: + TDB_CLEAR_IF_FIRST - clear database if we are the only one with it open + TDB_INTERNAL - don't use a file, instaed store the data in + memory. The filename is ignored in this case. + TDB_NOLOCK - don't do any locking + TDB_NOMMAP - don't use mmap + TDB_NOSYNC - don't synchronise transactions to disk + +---------------------------------------------------------------------- +TDB_CONTEXT *tdb_open_ex(char *name, int hash_size, int tdb_flags, + int open_flags, mode_t mode, + tdb_log_func log_fn, + tdb_hash_func hash_fn) + +This is like tdb_open(), but allows you to pass an initial logging and +hash function.

This allows tdb to + use read locks, which increases the parallelism possible during the + traversal. + + return -1 on error or the record count traversed + + if fn is NULL then it is not called + + a non-zero return value from fn() indicates that the traversal + should stop.

tdb

+ +TDB is a Trivial Database. In concept, it is very much like GDBM, and BSD's DB +except that it allows multiple simultaneous writers and uses locking +internally to keep writers from trampling on each other. TDB is also extremely +small. + +

Discussion and bug reports

+ +tdb does not currently have its own mailing list or bug tracking +system. For now, please use the samba-technical +mailing list, and the Samba +bugzilla bug tracking system. + +

Download

+ +You can download the latest release either via rsync or git.
+
+To fetch via git see the following guide:
+Using Git for Samba Development
+Once you have cloned the tree switch to the v4-0-test branch and cd into the source/lib/tdb directory.
+
+To fetch via rsync use these commands: + +
+  rsync -Pavz samba.org::ftp/unpacked/tdb .
+  rsync -Pavz samba.org::ftp/unpacked/libreplace .
+
+ +and build in tdb. It will find the replace library in the directory +above automatically. + + + -- 2.11.4.GIT
