• Revision 6ddf1e152a : Fix int64_t to unsigned int conversion warnings Use unsigned int type to store

  Fix int64_t to unsigned int conversion warnings

  Use unsigned int type to store the sse in the pixel domain. The
  precision is sufficient to handle sse of block size up to 64x64.
  The transform domain version however needs int64_t, since there is
  a transfer gain applied in the forward transformation that might
  cause unsigned int overflow.

• How to create a scheduled task – Introducing the Piwik Platform

  28 août 2014, par Thomas Steur — Development

  This is the next post of our blog series where we introduce the capabilities of the Piwik platform (our previous post was How to create a custom theme in Piwik). This time you’ll learn how to execute scheduled tasks in the background, for instance sending a daily email. For this tutorial you will need to have basic knowledge of PHP.

  What can you do with scheduled tasks ?

  Scheduled tasks let you execute tasks regularly (hourly, weekly, …). For instance you can :

  • create and send custom reports or summaries
  • sync users and websites with other systems
  • clear any caches
  • import third-party data into Piwik
  • monitor your Piwik instance
  • execute any other task you can think of

  Getting started

  In this series of posts, we assume that you have already set up your development environment. If not, visit the Piwik Developer Zone where you’ll find the tutorial Setting up Piwik.

  To summarize the things you have to do to get setup :

  • Install Piwik (for instance via git).
  • Activate the developer mode : ./console development:enable --full.
  • Generate a plugin : ./console generate:plugin --name="MyTasksPlugin". There should now be a folder plugins/MyTasksPlugin.
  • And activate the created plugin under Settings => Plugins.

  Let’s start creating a scheduled task

  We start by using the Piwik Console to create a tasks template :

  ./console generate:scheduledtask

  The command will ask you to enter the name of the plugin the task should belong to. I will simply use the above generated plugin name “MyTasksPlugin”. There should now be a file plugins/MyTasksPlugin/Tasks.php which contains some examples to get you started easily :

  class Tasks extends \Piwik\Plugin\Tasks
  
  {
  
      public function schedule()
  
      {
  
          $this->hourly('myTask');  // method will be executed once every hour
  
          $this->daily('myTask');   // method will be executed once every day
  
          $this->weekly('myTask');  // method will be executed once every week
  
          $this->monthly('myTask'); // method will be executed once every month
  
  
  
          // pass a parameter to the task
  
          $this->weekly('myTaskWithParam', 'anystring');
  
  
  
          // specify a different priority
  
          $this->monthly('myTask', null, self::LOWEST_PRIORITY);
  
          $this->monthly('myTaskWithParam', 'anystring', self::HIGH_PRIORITY);
  
      }
  
  
  
      public function myTask()
  
      {
  
          // do something
  
      }
  
  
  
      public function myTaskWithParam($param)
  
      {
  
          // do something
  
      }
  
  }

  A simple example

  As you can see in the generated template you can execute tasks hourly, daily, weekly and monthly by registering a method which represents the actual task :

  public function schedule()
  
  {
  
      // register method remindMeToLogIn to be executed once every day
  
      $this->daily('remindMeToLogIn');  
  
  }
  
  
  
  public function remindMeToLogIn()
  
  {
  
      $mail = new \Piwik\Mail();
  
      $mail->addTo('me@example.com');
  
      $mail->setSubject('Check stats');
  
      $mail->setBodyText('Log into your Piwik instance and check your stats!');
  
      $mail->send();
  
  }

  This example sends you an email once a day to remind you to log into your Piwik daily. The Piwik platform makes sure to execute the method remindMeToLogIn exactly once every day.

  How to pass a parameter to a task

  Sometimes you want to pass a parameter to a task method. This is useful if you want to register for instance one task for each user or for each website. You can achieve this by specifying a second parameter when registering the method to execute.

  public function schedule()
  
  {
  
      foreach (\Piwik\Site::getSites() as $site) {
  
          // create one task for each site and pass the URL of each site to the task
  
          $this->hourly('pingSite', $site['main_url']); 
  
      }
  
  }
  
  
  
  public function pingSite($siteMainUrl)
  
  {
  
      file_get_contents($siteMainUrl);
  
  }

  How to test scheduled tasks

  After you have created your task you are surely wondering how to test it. First, you should write a unit or integration test which we will cover in one of our future blog posts. Just one hint : You can use the command ./console generate:test to create a test. To manually execute all scheduled tasks you can execute the API method CoreAdminHome.runScheduledTasks by opening the following URL in your browser :

  http://piwik.example.com/index.php?module=API&method=CoreAdminHome.runScheduledTasks&token_auth=YOUR_API_TOKEN

  Don’t forget to replace the domain and the token_auth URL parameter.

  There is one problem with executing the scheduled tasks : The platform makes sure they will be executed only once an hour, a day, etc. This means you can’t simply reload the URL and test the method again and again as you would have to wait for the next hour or day. The proper solution is to set the constant DEBUG_FORCE_SCHEDULED_TASKS to true within the file Core/TaskScheduler.php. Don’t forget to set it back to false again once you have finished testing it.

  Starting from Piwik 2.6.0 you can alternatively execute the following command :

  ./console core:run-scheduled-tasks --force --token-auth=YOUR_TOKEN_AUTH

  The option “–force” will make sure to execute even tasks that are not due to run at this time. So you won’t have to modify any files.

  Which tasks are registered and when is the next execution time of my task ?

  The TasksTimetable plugin from the Marketplace can answer this question for you. Simply install and activate the plugin with one click by going to Settings => Marketplace => Get new functionality. It’ll add a new admin menu item under Settings named Scheduled Tasks.

  Publishing your Plugin on the Marketplace

  In case you want to share your task(s) with other Piwik users you can do this by pushing your plugin to a public GitHub repository and creating a tag. Easy as that. Read more about how to distribute a plugin.

  Advanced features

  Isn’t it easy to create scheduled tasks ? We never even created a file ! Of course, based on our API design principle “The complexity of our API should never exceed the complexity of your use case.” you can accomplish more if you want. For instance, you can define priorities, you can directly register methods from different objects and classes, you can specify at which time of a day a task should run and more.

  Would you like to know more about tasks ? Go to our Tasks class reference in the Piwik Developer Zone.

  If you have any feedback regarding our APIs or our guides in the Developer Zone feel free to send it to us.

  Add superframe support for frame parallel decoding.

  A superframe is a bunch of frames that bundled as one frame. It is mostly
  used to combine one or more non-displayable frames and one displayable frame.

  For frame parallel decoding, libvpx decoder will only support decoding one
  normal frame or a super frame with superframe index.

  If an application pass a superframe without superframe index or a chunk
  of displayable frames without superframe index to libvpx decoder, libvpx
  will not decode it in frame parallel mode. But libvpx decoder still could
  decode it in serial mode.

  Allocate buffers based on correct chroma format

  The encoder currently allocates frame buffers before
  it establishes what the chroma sub-sampling factor is,
  always allocating based on the 4:4:4 format.

  This patch detects the chroma format as early as
  possible allowing the encoder to allocate buffers of
  the correct size.

  Future patches will change the encoder to allocate
  frame buffers on demand to further reduce the memory
  profile of the encoder and rationalize the buffer
  management in the encoder and decoder.

  It is currently disabled by default using the flag multi_arf_enabled.

  Results are currently down somewhat in initial testing if
  multi-arf is enabled. Most of the loss is attributable to the
  fact that code to preserve the previous golden frame
  (in the arf buffer) in cases where we are coding an overlay
  frame, is currently disabled in the multi-arf case.

  for VP9. This patch fixes the maximum downscaling
  tests that are applied in the convolve function.

  The code used a maximum downscaling limit of x1/5
  for historic reasons related to the scalable
  coding work. Since the downsampling in this
  application is non-normative it will revert to
  using a separate non-normative scaler.

  Reuse inter prediction result in real-time speed 6

  In real-time speed 6, no partition search is done. The inter
  prediction results got from picking mode can be reused in the
  following encoding process. A speed feature reuse_inter_pred_sby
  is added to only enable the resue in speed 6.

  This patch doesn’t change encoding result. RTC set tests showed
  that the encoding speed gain is 2% - 5%.

  Make non-RD intra mode search txfm size dependent

  This commit fixes the potential issue in the non-RD mode decision
  flow that only checks part of the block to estimate the cost. It
  was due to the use of fixed transform size, in replacing the
  largest transform block size. This commit enables per transform
  block cost estimation of the intra prediction mode in the non-RD
  mode decision.

  Enable real-time version reference motion vector search

  This commit enables a fast reference motion vector search scheme.
  It checks the nearest top and left neighboring blocks to decide the
  most probable predicted motion vector. If it finds the two have
  the same motion vectors, it then skip finding exterior range for
  the second most probable motion vector, and correspondingly skips
  the check for NEARMV.

  The runtime of speed -5 goes down
  pedestrian at 1080p 29377 ms -> 27783 ms
  vidyo at 720p 11830 ms -> 10990 ms
  i.e., 6%-8% speed-up.

  For rtc set, the compression performance
  goes down by about -1.3% for both speed -5 and -6.
