  1. Tag messages, only send timeout if asked

    This changes the message protocol between the db_update_listener client
    and coordinator so that replies are tagged with the 'state' atom and
    Pid of the coordinator process.  Hopefully it avoids unexpected
    messages being treated as the State.  It also avoids sending a timeout
    message unless a 'get_state' request has arrived.  Previously we'd send
    extra 'timeout' messages and end up somewhat out-of-sync.
    Using a gen_fsm for the coordinator would seem to be the way to go here.

  1. Use a separate mailbox for 'db_updated' messages

    A continuous changes feed will decay with an active
    database as the controller mailbox is shared with the
    db updater notifier. This patch spawns a separate
    process to receive the 'db_updated' messages.

  1. Ignore 'complete' messages from suppressed workers

    If we have a database where one copy of a partition contributes zero
    rows to a reduce view but another copy of the same partition contributes
    one or more rows we can end up erroneously removing a worker which has
    already contributed a row to a response.  This puts the coordinator into
    an inconsistent state and can ultimately cause the response to hang.
    The fix is simple -- just guard processing of 'complete' messages by
    checking if the worker sending the message has already lost the race to
    another copy.

  1. Tolerate whitespace in BC sequences

    If a BC update sequence is parsed as JSON and formatted back to a
    string it may pick up internal whitespace. unpack_seqs now tolerates this.

  1. Remove clause that converts error tuple to ok tuple

    force_reply/3 now checks for errors like conflict and if all are the same for
    a given doc, it uses the value of Health, otherwise an error tuple is returned
    and handled in the chttpd layer.

  2. Change callback fun to return error tuple

    and change fabric_view:remove_down_shards to expect an error tuple

    Bob Dionne committed Jan 18, 2012
  3. Fix callback error handling in fabric:design_docs

    fabric_view:remove_down_shards invokes the callback with an error tuple
    and expects an ok response, which it returns as an error to the controller.

  1. Fix bad prepend value caused by timeouts

    When timeouts occur receive_results in fabric_view_changes was using the
    original returned response from initial start callback rather than the current
    value in the accumulator within the state. Thus it lost the comma needed for
    prepending in subsequent calls.

  1. fix missed error case in doc update

    If a write fails to meet quorum, returning a 202 accept, a subsequent
    write of the same doc will return an update conflict but also an error
    tuple as nodes could be down. This patch handles that edge case, ensuring
    a 409 conflict is returned.

  1. Ensure response with needs repair contains the correct value

    For example we may have responses like (1-foo, 2-bar, 1-foo) where we've
    reached a quorum with 1-foo but 1-foo is an ancestor of 2-bar which is the
    correct answer. In this case we don't want to respond with 1-foo. This patch
    ensures that after remove_ancestors is called the remaining response is the
    same as the one that made quorum. So (1-foo, 2-bar, 2-bar) would respond with
    2-bar needs repair and (1-foo, 2-bar, 1-foo) would block with read repair.

  1. Correctly support old-style update_seq in unpack_seqs

    The regexp in unpack_seqs permits - anywhere, causing a full
    old-style update_seq to match, rather than just the opaque part.
    This patch prevents that and adds unit tests to prove it.

  1. Fix the changes feed.

    The handling of timeout messages in fabric_view_changes:handle_message/3
    was incorrectly discarding updates to the state. This means that we
    could accidentally discard things like the handling of rexi_EXIT
    messages which would then later lead to an infinite wait in
    rexi_utils:recv/6 because we forgot that the node died.
