Added the ability to store transport configuration details in the
...
database - unlike transport properties, these are not shared with
contacts. For example, when using email as a transport, the address
for sending and receiving emails would be a transport property, while
the username and password for the email server would be transport
configuration details. Transport plugins can update their
configuration details atomically.
Also clarified the terminology for transport and subscription updates.

Changed the format of transport properties from (key, value) pairs to
...
(transport name, key, value) triples. This makes it possible for each
transport plugin to update its locally stored properties atomically.

Allow a maximum length to be specified when reading strings or byte
...
arrays, check it before allocating the buffer, and always specify the
maximum length when reading untrusted data - otherwise
CountingConsumer will reject the packet, but not before we've tried to
allocate a buffer of the specified size (up to 2 GB).

Replaced assertions with exceptions in database code, and changed

exception handling so that database connections aren't closed with

needed - this will make it possible to read to the end of a packet and

Use the combination of batch ID and contact ID as the primary key for

received and sent batches, since batches sent to or received from
different contacts may contain identical lists of messages and
therefore have identical IDs.

If no messages are added to a batch, don't call BatchWriter.finish() -
...
this allows the caller to avoid creating an empty packet by delaying
creation of the packet's header and trailer until something's written
to the packet's body. Changed the return semantics of
DatabaseComponent.generateBatch(ContactId, BatchWriter,
Collection<MessageId>) so that the IDs of messages considered for
inclusion in the batch but no longer sendable are also returned - this
allows the caller to remove them from the set of requested IDs.
