Subject: [reSIProcate] MessageWaitingContexts: a bit wrong encoding

 

Hello resiprocate developers.

 

In order to implement MWI feature in my application I made simple notifier that works as my voice mail server and sends towards me NOTIFY messages with bodies using MessageWaitingContexts class.

 

For example, in ServerSubscriptionHandler::onNewSubscription () I call:

Data Txt ("Messages-Waiting: yes\r\n"

          "Message-Account: sip:a@xxxxxxxxxxx\r\n"

          "Voice-Message: 2/1 (1/0)\r\n");

HeaderFieldValue Hfv (Txt.begin (), Txt.size ());

MessageWaitingContexts Mwc (& Hfv, Mime ("application", "message-summary");

 

Unfortunately, encoder of MessageWaitingContexts class produces a bit wrong output and after the message is encoded I get exactly following:

 

Messages-Waiting: yes\r\n

sip:a@xxxxxxxxxxxxxxxxxxxxxxxx: 2/1(1/0\r\n

 

That is the encoder doesn't place "Message-Account:" at the start of the second line, doesn't add "\r\n" at its end, forgets to place space character before '(' in case there are urgent messages and doesn't add ')' after urgent counters.

 

I slightly changed encoder and now it works as expected. I get correct (to my mind) output:

Messages-Waiting: yes\r\n

Message-Account: sip:a@xxxxxxxxxxx\r\n

voice-message: 2/1 (1/0)\r\n

 

Here are the changes (signed with “added by S.Y.”) I did in function
MessageWaitingContents::encodeParsed:

 

...

if (exists(mw_account))

{

s << "Message-Account" << Symbols::COLON[0] << Symbols::SPACE[0]; //* added by S.Y. the entire line

      header(mw_account).encode(s);

      s << Symbols::CRLF; //* added by S.Y. the entire line

}

 

for(int i = 0; i < (int)MW_MAX; i++)

{

if (mHeaders[i] != 0)

      {

            s << MessageHeaders[i] << Symbols::COLON[0] << Symbols::SPACE[0]

              << mHeaders[i]->mNew << Symbols::SLASH[0]

              << mHeaders[i]->mOld;

            if (mHeaders[i]->mHasUrgent)

            {

                  s << Symbols::SPACE[0] << Symbols::LPAREN[0]    //* added by S.Y. SPACE[0]

                  << mHeaders[i]->mUrgentNew << Symbols::SLASH[0]

                  << mHeaders[i]->mUrgentOld << Symbols::RPAREN[0]; //* added by S.Y. RPAREN[0]

            }

 

            s << Symbols::CRLF;

      }

}

...

 

 

Best regards,

Sasha.
