[FOSSology] Fossology Agent

Mon, 10 May 2010 07:10:06 -0700
Thanks, it works much better: I can see my agent in the list when I type fossjobs -a ! Now I face another problem related to dependencies between jobs, when I do a: 
fossjobs -vvv  -A "agent_license,Hfoss_trigger" -U 43
I would like Hfoss_trigger to be scheduled after agent_license (wether this is a first scan or a reschedule) since this is a end of job notifier which triggers a process when an upload analysis is complete. 
Do you have documentation about dependencies setup / JobQueueAdd usage ?

Cheers,

Hi Phil,
I think you need one more thing to do: You need to create a user interface plugin or command-line interface to scheduler jobs for your new agent. I create an simple example for you, you need add this plugin under /usr/share/fossology/www/plugins/, and run fossjobs –a, I think you can see your agent list. 


<?php

global $GlobalReady;

if (!isset($GlobalReady)) { exit; }


class Hfoss_trigger extends FO_Plugin

{

  public $Name       = " Hfoss_trigger ";

  public $Title      = " Hfoss_trigger  agent";

  public $Version    = "1.0";

  public $Dependency = array("db");

  public $DBaccess   = PLUGIN_DB_ANALYZE;

  /***********************************************************

   RegisterMenus(): Register additional menus.

   ***********************************************************/

  function RegisterMenus()

    {

    if ($this->State != PLUGIN_STATE_READY) { return(0); } // don't run

    menu_insert("Agents::" . $this->Title,0,$this->Name);

}

  /*********************************************

   AgentCheck(): Check if the job is already in the

   queue.  Returns:

     0 = not scheduled

     1 = scheduled but not completed

     2 = scheduled and completed

  *********************************************/

  function AgentCheck($uploadpk)

  {

    global $DB;
$SQL = "SELECT jq_pk,jq_starttime,jq_endtime FROM jobqueue INNER JOIN job ON job_upload_fk = '$uploadpk' AND job_pk = jq_job_fk AND jq_type = ' Hfoss_trigger ';"; 

    $Results = $DB->Action($SQL);

    if (empty($Results[0]['jq_pk'])) { return(0); }

    if (empty($Results[0]['jq_endtime'])) { return(1); }

    return(2);

} // AgentCheck()

 /*********************************************

      $Depends is for specifying other dependencies.

      $Depends can be a jq_pk, or an array of jq_pks, or NULL.

   *********************************************/

  function AgentAdd ($uploadpk,$Depends=NULL,$Priority=0)

  {

    global $DB;


    /* Prepare the job: job " Hfoss_trigger Agent" */

    $jobpk = JobAddJob($uploadpk," Hfoss_trigger Agent ",$Priority=0);
if (empty($jobpk) || ($jobpk < 0)) { return("Failed to insert job record"); }
/* Add job: job " Hfoss_trigger " has jobqueue item " Hfoss_trigger " */
$jobqueuepk = JobQueueAdd($jobpk," Hfoss_trigger ","","no",NULL,$Depends,TRUE);
if (empty($jobqueuepk)) { return("Failed to insert testagent into job queue"); } 

    return(NULL);

    } // AgentAdd()

 };

 $NewPlugin = new Hfoss_trigger;

?>


Hope can help you.

  Hello,
I have not yet found an answer to this pb ... but to use a modified version of fo_notify. 
Any help would be welcome

Cheers,

        Hello,
I want to write an agent which would trigger the update of a portal on job completion. I launch the job analysis in batch mode, using cp2foss or fossjobs 
        (no UI).
For a start, I took the quick and dirty approach using engine-shell as 
        explained in http://www.fossology.com/how_to_create_an_agent


        - I wrote a bash script implementing the trigger in
        /usr/lib/fossology/agents/Hfoss_trigger_agent - I modified
        /etc/fossology/Scheduler.conf to include my agent
agent=Hfoss_trigger host=localhost | /usr/lib/fossology/agents/engine-shell 
        Hfoss_trigger  '/usr/lib/fossology/agents/Hfoss_trigger_agent %{*}'


        But I must be missing smth because if I try to:

          cp2foss -q 'agent_unpack,agent_license,Hfoss_trigger'   
/path/to/upload


        Or fossjobs -A "agent_unpack,agent_license,Hfoss_trigger" -U 20

        the agent is not called by the scheduler.


        If I look at fossology.log, I see that the scheduler is aware of my 
agent:
"scheduler[28741] : Child[15] 'agent=Hfoss_trigger host=localhost ' 
        state=FREE(1)"


        Can somebody tell me what is wrong?


        Thanks

    Phil,


    I'm looking into this now. No updates at this point. I am going to
    try to reproduce your situation. One question. Do you see your
    agent if you do a fossjobs -a ? More after I investigate.

Bonjour,
my config is : 
   CentOS release 5.4
   Fossology RPM  fossology-1.1.0-1.el5
[r...@santos ~]# fossjobs -a 
The available agents are:
agent_license
agent_mimetype
agent_pkgmetagetta
agent_specagent
agent_unpack
My agent Hfoss_trigger is not listed. -- Phil
