• Remove Plan 9 support

  29 novembre 2016, par Diego Biurrun

  Remove Plan 9 support
  Supporting the system was a nice joke for the 9 release, but it has
  
  run its course. Nowadays Plan 9 receives no testing and has no
  
  practical usefulness.

• Anomalie #3635 : Pouvoir déplacer les rubriques qui contiennent des brèves avec le plugin plan

  11 février 2017

  Les brèves sont forcément attachées à un secteur (pas à une rubrique directement quoi). Lorsqu’on déplace une rubrique qui a des brèves ailleurs, les brèves sont réaffectées au secteur de la rubrique de destination (si on coche la case de confirmation).

  Dans le cas du plan, actuellement effectivement, c’est comme si on ne cochait pas la case de confirmation.
  Est-ce une bonne idée de rendre transparent cette action de réaffectation des brèves d’une rubrique au secteur si on déplace une rubrique ?
  En tout cas ça serait dans https://zone.spip.org/trac/spip-zone/browser/_core_/plugins/plan/action/deplacer_objets.php#L60 actuellement :

  $modifs = array(’id_parent’ => $id_rubrique_new) ;
  // exception pour confirmer automatiquement le déplacement des brèves (ou autres).
  if ($objet == ’rubrique’) 
      $modifs[’confirme_deplace’] = ’oui’ ;
  
  

• ffmpeg azure function consumption plan low CPU availability for high volume requests

  27 novembre 2017, par The Lemon

  I am running an azure queue function on a consumption plan ; my function starts an FFMpeg process and accordingly is very CPU intensive. When I run the function with less than 100 items in the queue at once it works perfectly, azure scales up and gives me plenty of servers and all of the tasks complete very quickly. My problem is once I start doing more than 300 or 400 items at once, it starts fine but after a while the CPU slowly goes from 80% utilisation to only around 10% utilisation - my functions cant finish in time with only 10% CPU. This can be seen in the image shown below.
  Does anyone know why the CPU useage is going lower the more instances my function creates ? Thanks in advance Cuan

  edit : the function is set to only run one at a time per instance, but the problem exists when set to 2 or 3 concurrent processes per instance in the host.json

  edit : the CPU drops get noticeable at 15-20 servers, and start causing failures at around 60. After that the CPU bottoms out at an average of 8-10% with individuals reaching 0-3%, and the server count seems to increase without limit (which would be more helpful if I got some CPU with the servers)

  Thanks again, Cuan.

  I’ve also added the function code to the bottom of this post in case it helps.
