[pybsddb] bdb replica node problem

[Yingbo Qiu]

BTW: I think pybsddb's DBEnv object should supply a method to assign
some private item value.

I have to use global variable to pass it into event_callback function.

for example: db-4.7.25/examples_c/ex_rep/mgr/rep_mgr.c

static void
event_callback(dbenv, which, info)
    DB_ENV *dbenv;
    u_int32_t which;
    void *info;
{
    APP_DATA *app = dbenv->app_private;
    SHARED_DATA *shared = &app->shared_data;

    info = NULL;                /* Currently unused. */

    switch (which) {
    case DB_EVENT_REP_CLIENT:
        shared->is_master = 0;
        break;

    case DB_EVENT_REP_MASTER:
        shared->is_master = 1;
        break;
....

With pybsddb, programmer just set "shared" to a global variable. :(
