示例1: shardVersionOk
/**
* @ return true if not in sharded mode
or if version for this client is ok
*/
bool shardVersionOk( const string& ns , bool isWriteOp , string& errmsg ){
if ( ! shardingState.enabled() )
return true;
ShardedConnectionInfo* info = ShardedConnectionInfo::get( false );
if ( ! info ){
// this means the client has nothing sharded
// so this allows direct connections to do whatever they want
// which i think is the correct behavior
return true;
}
if ( info->inForceMode() ){
return true;
}
ConfigVersion version;
if ( ! shardingState.hasVersion( ns , version ) ){
return true;
}
ConfigVersion clientVersion = info->getVersion(ns);
if ( version == 0 && clientVersion > 0 ){
stringstream ss;
