示例1: saveConfigLocally
/* comment MUST only be set when initiating the set by the initiator */
void ReplSetConfig::saveConfigLocally(bo comment) {
checkRsConfig();
log() << "replSet info saving a newer config version to local.system.replset" << rsLog;
{
writelock lk("");
Client::Context cx( rsConfigNs );
cx.db()->flushFiles(true);
//theReplSet->lastOpTimeWritten = ??;
//rather than above, do a logOp()? probably
BSONObj o = asBson();
Helpers::putSingletonGod(rsConfigNs.c_str(), o, false/*logOp=false; local db so would work regardless...*/);
if( !comment.isEmpty() && (!theReplSet || theReplSet->isPrimary()) )
logOpInitiate(comment);

}
log() << "replSet saveConfigLocally done" << rsLog;
