the code try: root = self._getRoot() ... except: self._closeDB(root) self._delDB() raise which fails with an UnboundLocalError if the first line in the try clause fails. Fixed this by setting 'root = None' before each such try clause, and adding a None check to _closeDB(). Also removed a useless 'root = None' from the body of _closeDB(). Barry: I saw this in the saz 1.0c1 release. Is it worth backporting? Probably not given that we're not going to do a merge pre-1.0.

Put the tpc_begin() -> tpc_finish() in a try/except. If an error occurs, abort the current transaction and re-raise the error. It appears that some storages (well, only Standby Storage) has trouble shutting down if a transaction is in progress.

Replace three small integers with symbolic constants. TRANS_HDR_LEN = 23 DATA_HDR_LEN = 42 DATA_VERSION_HDR_LEN = 58 The constants make it easier to remember what kind of header is being read and/or what kind of offset is being computed. Refactor commitVersion(): - Keep locking & arg checking in commitVersion(), but move actual commit logic to _commitVersion(). This removes a level of indentation. - Remove local vars that alias attributes of other vars Add a few more POSKeyError exceptions.

Highlights: BaseStorage.py: Fix copyTransactionsFrom() when commitVersion(), abortVersion() or transactionalUndo() is used. FileStorage.py: Add restore() method, which can store data records corresponding to undo or version manipulations; add close() method to FileIterator class; raise POSKeyError instead of KeyError for bad keys, to ensure safe formatting of transaction ids (binary strings) in tracebacks. POSException.py: Add POSKeyError. fsdump.py: Deal with records indicating the undo or abort of a version doing object creation. tests/IteratorStorage.py: New unittests for the iterator() method and interface of the storage API; new unit tests for extended file iterators; new class, IteratorDeepCompare; test of the iterator .close() method. tests/testFileStorage.py: Add class FileStorageRecoveryTest, which adds two simple tests for copyTransactionsFrom(). This indirectly tests the new restore() method.

1. The exception is in serial, not arg. 2. Must call handle_serials() before tpc_finish(), because handle_serials() may raise an exception that causes the transaction to abort.

Make sure that the test undoes an object creation and make sure that the iterator for that transaction return None for the data attribute.

This will allow an iterator to handle aborted versions and undone object creations. XXX Still need a test for the latter.

XXX checkTransactionalUndoIterator() should too, but doesn't.

# XXX need a test case that covers iteration over a storage that # includes a transactional undo that un-created an object.

If supplied, they are stored as metadata on the transaction object. This is helpful for debugging.

It's not thread-safe to store a Transaction() object in an instance variable without some sort of locking. Nor is it desirable to use the same transaction object for more than one transaction. So get rid of all uses of self._transaction and replace with a local variable.

The Standby-branch was branched from the StandaloneZODB-1_0-branch, which includes the BTrees-fsIndex code. I didn't include that change in the merge, but everything else. Terse summary follows: BTreeModuleTemplate.c: Greg Ward's ConflictError patch
