"""Smart-server protocol, client and server.
This code is fairly complex, so it has been split up into a package of modules,
rather than being a single large module. Refer to the individual module
docstrings for details.
Server-side request handlers are registered in the `bzrlib.smart.request`
module.
The domain logic is in `bzrlib.remote`: `RemoteBzrDir`, `RemoteBranch`,
and so on.
There is also an plain file-level transport that calls remote methods to
manipulate files on the server in `bzrlib.transport.remote`.
The protocol is described in doc/developers/network-protocol.txt.
"""
from __future__ import absolute_import
# TODO: A plain integer from query_version is too simple; should give some
# capabilities too?
# TODO: Make each request and response self-validatable, e.g. with checksums.
#
# TODO: is it useful to allow multiple chunks in the bulk data?
#
# TODO: If we get an exception during transmission of bulk data we can't just
# emit the exception because it won't be seen.
# John proposes: I think it would be worthwhile to have a header on each
# chunk, that indicates it is another chunk. Then you can send an 'error'
# chunk as long as you finish the previous chunk.
#
# Promote some attributes from submodules into this namespace
