| * | Batch updates•••The extension example_module was extended to introduce a new
client-initiated batch type named test. This is primarily done to ease
testing of the client-initiated portions of m_batch, but also serves as
a useful sketch for how a module can register its own client-initiated
batch types.
The definition of struct BatchHandler was slightly modified to use a
callback function to determine if nesting is allowed. The callback can
additionally set a custom error message if desired when returning false.
The len and messages list in struct Batch no longer include the start
message, so a len of 0 indicates an empty batch. Because the start
message is still allocated and saved off, adjust anything that impacts a
client's pending_batch_lines by 1 to account for the implicit additional
message.
Empty batches now trigger the relevant batch handler. If a handler wants
to no-op on empty batches, it can do so but this allows additional
flexibility for handlers to still do something upon receiving empty
client-initiated batches.
