WaitSet API explanation require

[stalker]

Hello Everybody,

I found very less information about WaitSet API of zimbra on internet. I just found this doc /opt/zimbra/docs/soap-waitset.txt. But it doesn't explain much about it.

Can anybody explain me what is the use of WaitSet API and how it works?

I would like to sync appointments as they changes.

Thanks,
stalker.

Can anyone help out with this ?

I have tried integrating this functionality, and find it very unreliable - but it may be because I am not calling it properly. For example - calling the api with a timeout of "30" and getting some responses after 24 seconds and others after 37 seconds - when nothing is changing on that mailbox.

Anyone got a decent code sample for it's use ?

There is no proper code snippet for it. Can you brief what exactly you're doing?

I am calling the 3 Waitset SOAP functions in sequence within a php function.

Basically, I am trying to wait for changes on an account - and then to parse through the changes to see if any relevant ones have occurred.

But when I call the WaitSetRequest with a 30 second timeout - I am getting back responses in a very unpredictable manner. Sometimes too fast - other times too slow. No consistency.

This is just an extract from the code where I built the calls to the WaitSet functions and parse the responses.

It does not include the blocks of code that actually make the curl calls, and parse the XML, etc. but it should be enough for you to understand how I am trying to use the API.

            $soap = '<CreateWaitSetRequest  defTypes="all" xmlns="urn:zimbraMail" >
                          <add><a id="'.$this->_zimbraId.'" /></add>
                     </CreateWaitSetRequest>';
debugLog( 'CreateWaitSetRequest ['.$soap.']' );

            $response = $this->SoapRequest($soap);
            if($response) {

debugLog( 'CreateWaitSetResponse: ' . print_r( $response, true ) );

                $array = $this->MakeXMLTree($response);
//debugLog( 'Response '.print_r( $array, true ) );

                unset($response);
				
                $this->_pingtokenOne = $array['soap:Envelope'][0]['soap:Header'][0]['context'][0]['change'][0]['token'];
debugLog( 'Token ['.$this->_pingtokenOne.']' );

                $this->_waitSetId = $array['soap:Envelope'][0]['soap:Body'][0]['CreateWaitSetResponse'][0]['waitSet'];
                $this->_highestSeqKnown = $array['soap:Envelope'][0]['soap:Body'][0]['CreateWaitSetResponse'][0]['seq'];
debugLog( 'WaitSetResponse: SEQ [' .$this->_highestSeqKnown. ']' );
            }

debugLog( "Calling WaitSetRequest for 30 seconds" );

            $soap = '<WaitSetRequest  waitSet="'.$this->_waitSetId.'" defTypes="all" seq="'.$this->_highestSeqKnown.'" block="1" timeout="'.$timeout.'" xmlns="urn:zimbraMail" >
                         <update>
                             <a id="'.$this->_zimbraId.'" token="'.$this->_pingtokenOne.'" />
                         </update>   
                     </WaitSetRequest>';
debugLog( 'WaitSetRequest ['.$soap.']' );

            $response = $this->SoapRequest($soap);
            if($response) {

debugLog( 'WaitSetResponse ['.$this->_pingtokenOne.']: ' . print_r( $response, true ) );

                $array = $this->MakeXMLTree($response);
//debugLog( 'Array '. print_r( $array, true ) );

                unset($response);
				
                $this->_highestSeqKnown = $array['soap:Envelope'][0]['soap:Body'][0]['WaitSetResponse'][0]['seq'];

debugLog( 'WaitSetResponse: SEQ [' .$this->_highestSeqKnown. ']' );
            }

            $soap = '<DestroyWaitSetRequest  waitSet="'.$this->_waitSetId.'"  xmlns="urn:zimbraMail" />';
debugLog( 'DestroyWaitSetRequest ['.$soap.']' );

            $response = $this->SoapRequest($soap);
            if($response) {

debugLog( 'DestroyWaitSetResponse ['.$this->_pingtokenOne.']: ' . print_r( $response, true ) );

                $array = $this->MakeXMLTree($response);
//debugLog( 'Array '. print_r( $array, true ) );

                unset($response);
            }

That means you have problem in response time not in response right?

Actually, it seems like I did a disservice earlier.

I have since added some more debugging to my code, and it turns out that the phone I am testing with is opening multiple simultaneous sessions with the server.

Each of the sessions is behaving as it should as far as I can tell. Opening a WaitSet, waiting for the 30 seconds, then closing the WaitSet.

Not sure why the multiple sessions are getting opened - but it is looking more promising than I first thought.

The sequence of calls I have used appears to be good.

Well, I've less idea about PHP's behavior of calling methods based on time interval. But you can also use javascript for that as well.
