  1. Treat empty vclocks as undefined ones

    Vagabond committed May 31, 2011
    This works around a bug in the python protobuff library that deserilizes
    optional fields that are not supplied as an empty string.
  2. Fix reduceMin and reduceMax.

    seancribbs committed with Kelly McLaughlin Jan 17, 2011
    Javascript's sort() function sorts lexically and thus will not sort
    numbers correctly without a comparator function. Reduce/fold is the
    proper way to find a minimum or maximum.

  1. Catch exit with reason exhausted_preflist on the

    Kelly McLaughlin committed May 26, 2011
    call to schedule_input after a nodedown message
    is received.
    Fixes: az449 bz1113 bz1114
    The schedule_input function in riak_kv_map_phase calls itself
    in the case that it catches a nodedown exit while trying to
    start mapper processes. If all the primary preference list
    entries have been checked or their nodes are down this inner
    call to schedule_input will result in an exit with reason
    exhausted_preflist. Instead of just having the map phase
    process exit, this change catches the exit and returns an
    error to the caller of schedule_input so that notfound results
    can be returned in the case of bz1113 or a more descriptive
    error message can be return in the case of bz1114.
    Do not expect an empty list for the ClaimList
    parameter in the termination clause of
    Add extra function clause for riak_kv_mapred_planner:claim_keys.

  1. Erase the reference to a map executor in the case of a notfound

    Kelly McLaughlin committed May 26, 2011
    instead of decrementing the input counter.
    Fixes: az445 bz1112
    When a notfound error occurs during a map phase the phase creates a new map plan and retries using a difference preference list entry. A lingering reference to the original map phase executor used to track input counts was the source of the error. The solution is to remove the reference to the original map phase executor in the case of a notfound error instead of simply decrementing the associated counter.

  1. Fix problem of erroneous data being returned while running concurrent

    Kelly McLaughlin committed May 23, 2011
    MapReduce jobs.
    Fixes: az432 bz1104
    The riak_kv_js_vm module used a finite set of 25 integers appended to
    to a variable name as a means to identify anonymous javascript functions
    in order to reuse functions and make MapReduce processing more efficient.
    The limit was set to 25 presumably to prevent too much resource consumption
    by the JS VM.
    The bug described by bz1104 is due reuse of this small set of ids and
    results in unexpected code being executed and MapReduce results being
    contaminated. The solution is to move the assembly of anonymous
    javascript functions from erlang_js into the riak_kv_js_vm module.
    This is does not decrease the efficiency of MapReduce execution because
    each javascript function is compiled before each execution and
    destroyed after execution. The only remnant of a previously executed
    anonymous function was a local variable that could be reused. By moving
    the function that assembles the anonymous functions to riak_kv_js_vm and
    eliminating lookups for any previously defined functions the code is
    simplified, there is no concern about id reuse, and there is no chance
    of memory accumlation on the JS VM due to large numbers of anonymous
    javascript functions being used.
    Remove the state argument from the define_anon_js function in riak_kv_js_vm.
    Remove unused anon_funs field from state record in riak_kv_js_vm module.

    tags: az327
    The fix to address bz1006 causes notfound error information to be excluded
    from the results of a MapReduce even if the inclusion is requested by
    the client. This changes corrects that by adding a Reply parameter to
    the handle_not_found_reply function and ensuring that after the
    final preference list entry has been checked that Reply is appended
    to the phase state's pending value.
    Add test cases for riak_kv_mapreduce:map_object_value to show that
    the include_notfound and filter_notfound actions work as expected.

    …to prevent
    the termination of all active MapReduce jobs if a single MapReduce job times

    Fixes: AZ340
    Handle the case of an error tuple being returned from the calls to
    riak_kv_mapper_sup:new_mapper in riak_kv_map_master so that a timeout
    does not cause riak_kv_map_master to terminate and take all active
    MapReduce jobs with it.
    Change riak_kv_map_master so that it does not monitor mapper processes
    and instead trap exits and rely on the link to the mapper proesses
    to detect when the mapper process terminates.
