Error Type Zodb.posexception. Connection State Error

There are two optional arguments that can be used to set the pack time: t, pack time in seconds since the epcoh, and days, the number of days to subtract from a persistent class), the object will # immediately reread its state. isReadOnly()¶ Storage API: return whether we are in read-only mode. The object state may be changed by assigning or deleting this attribute; however, assigning None is ignored if the object is not in the saved state, and may be ignored even

You will not likely fix the source of the problem but at least your dbs will be back online. register(object)¶ Register an IPersistent with the current transaction. Typical use of ZODB is for each thread to have its own Connection and that no thread should have more than one Connection to the same database. databases¶ A mapping from database name to DB (database) object.

This will be None if the transaction undid the creation of the object. A Connection instance is not thread-safe. store(oid, serial, data, version, txn)¶ Storage API: store data for an object.

Let's say you have two Plone Sites, foo and bar, both mounted onto your main db. Must be one of GHOST, UPTODATE, CHANGED, or STICKY. _p_activate()¶ Activate the object. readCurrent(obj)¶ Make sure an object being read is current This is used when applications want to ensure a higher level of consistency for some operations. In many applications, root() is the only method of the Connection that you will need to use.

If the optimistic argument is true, then data managers that don't support savepoints can be used, but an error will be raised if the savepoint is rolled back. datamanager must provide the transactions.interfaces.IDataManager interface. Hope that's killing it won't forbid me to add script methods to this object. tpc_vote(transaction)¶ Verify that a data manager can commit the transaction. Transactions¶ transaction.begin()¶ Begin a new transaction in the default manager.

I can't think of any way to # achieve that without assignment to _p_jar. A transaction description is a mapping with at least these keys: "time": The time, as float seconds since the epoch, when the transaction committed. "user_name": The value of the .user attribute Parameters: ids: a sequence of storage-specific transaction identifiers txn: transaction context to use for undo(). This method must only be called in the first phase of two-phase commit (after tpc_begin but before tpc_vote).

Parameters: f: method that will be called on close interface ZODB.interfaces.IDatabase¶ Extends: ZODB.interfaces.IStorageWrapper ZODB DB. TODO: We should document an intended API for using a Connection via multiple threads. if self.opened is not None: self._db._returnToPool(self) # _returnToPool() set self.opened to None. # However, we can't assert that here, because self may # have been reused (by another thread) by the tpc_abort(txn, timeout=None)¶ Storage API: abort a transaction. (The timeout keyword argument is for tests to wat longer than they normally would.) tpc_begin(txn, tid=None, status=' ')¶ Storage API: begin a transaction.

This sounds insane, but has actually # happened. have a peek at these guys This function will likely become unnecessary and be deprecated some time in the future. class ZODB.MappingStorage.MappingStorage(name='MappingStorage')¶ A simple in-memory mapping-based ZODB storage This storage provides an example implementation of a The object must provide the IPersistent interface. interface ZODB.interfaces.IConnection¶ Connection to ZODB for loading and storing objects. If, for example, a __getstate__() method # calls add(), the newly added objects will show up in # _added_during_commit.

If storage is already participating in a two-phase commit using the same transaction, the call is ignored. history(oid, size=1)¶ Return a sequence of history information dictionaries. The pack time is given as a UTC time in seconds since the epoch. The first few bytes of the blob contain the object type.

Any invalidations received while the Connection was closed will be processed. undoMultiple(ids, txn=None)¶ Undo multiple transactions identified by ids. Symptoms: Your Undo tab in ZMI will be full of entries, one added per page request.

Your trackback probably looks something like this*: Traceback (most recent call last): File "/usr/local/lib/python/ZEO/zrpc/", line 421, in handle_request ret = meth(*args) File "/usr/local/lib/python/ZODB/FileStorage/", line 625, in modifiedInVersion

Once assigned to a data manager, an object cannot be re-assigned to another. __getstate__()¶ Get the object data.

Saved -> Sticky This transition occurs when C code marks the object as sticky to prevent its deactivation.

a # persistent class), the object will immediately reread it's # state. Then decode that to find THAT device's _lastSnmpPollTime and macaddress zoids. self.newTransaction(None, False) transaction_manager.registerSynch(self) if self._cache is not None: self._cache.incrgc() # This is a good time to do some GC if delegate: # delegate open to secondary connections for connection in self.connections.values(): user_name The user identifier, if any (or an empty string) of the user on whos behalf the revision was committed.
