1116458 - Some functions of nsINetworkService cannot be called interleavingly.

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Wifi, defect)

Description

[Henry Chang [:hchang]]

nsINetworkService provides a set of functions about networking but some of them which require netd command chain cannot be called interleavingly. That means, one function has to be called after the previous one is called back. It is inconvenient for calling nsINetworkSerive functions in a row.

Is it possible we move this into PostMessage and check the |aResult| value ?
Only call finalize when result is success. I am not sure if there is any chance
that result is success but we don't have to call finalize

Since there's no standard way to tell if a operation is successful
or not (some uses mRet and some uses mSuccess), it's difficult to knwo 
when we should call to finalize in PostMessage whereas xxxxSuccess 
explicitly suggests success.


By the way, I forgot to add finalizeSuccess to updateUpStreamSuccess
