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. - -*/ - -struct tdb_transaction_el { - struct tdb_transaction_el *next, *prev; - tdb_off_t offset; - tdb_len_t length; - unsigned char *data; -}; - -/* - 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 elements.
