• Evolution #3955 : Amélioration de l’API de détection et de changement de langue

  6 juin 2017, par RastaPopoulos ♥

  De la navigation ? C’est surtout une amélioration de l’API de cherchage de langue, et d’application et de langue et son enregistrement en cookie, à mon avis.

  Concrètement il faudrait :
  - une fonction générique pour chercher la langue préférée de l’utilisateurice modulo les langues réelles du site (= renvoyer la langue du site que préfère la personne) : chercher_langue_preferee()
  - que utiliser_langue_preferee() applique la langue préférée, mais qui existe vraiment dans le site, cf apparemment les modifs qu’a dû faire Real3T
  - une fonction générique pour enregistrer une langue donnée en paramètre dans la session/le cookie de la personne qui visite le hit, apparemment on n’a pas de fonction qui fait ça proprement : enregistrer_lanngue_visiteur($lang) ?
  - éventuellement, avoir directement une fonction qui combine tout : qui cherche la langue préférée, qui la garde en mémoire chez la personne, et qui l’applique pour le hit en cours : enregistrer_langue_preferee() ?
  - avoir une constante qui permet d’activer ce comportement directement (du genre _LANG_ENREGISTRER_PREFEREE) sans rien avoir à coder soi-même ! Et qui serait donc à appliquer par les squelettes qui ont besoin de ce comportement
  - éventuellement avoir une option pour activer ça par interface humaine, mais qui ne serait active que si la constante n’est pas définie ! (si la constante est définie, alors l’option est grisée avec sa valeur définie dans la constante, et une phrase expliquant que c’est déjà définie dans le code : "Le comportement de recherche de la langue préférée est déjà défini dans le code de votre site.")

  Peut-être aussi qu’il serait pas mal de rendre cohérent toutes les fonctions en les préfixant pareilles, lang_chercher_preferee(), lang_utiliser_preferee(), lang_enregistrer($lang), lang_enregistrer_preferee(), avec les anciennes fonctions toujours là qui appelleraient les nouvelles.

  Voilà tout ce qui m’est venu pour rendre tout ça cohérent, lisible, facile à apprendre et retenir.

• How to Terminate a Process Normally Created using ProcessBuilder

  30 janvier 2015, par Bilal Ahmed Yaseen

  I am creating Processes using ProcessBuilder in my Java Application. The created process executes some FFMPEG commands which actually copy the RTSP streams in specified destination media file.

  ProcessBuilder builder = new ProcessBuilder("ffmpeg", "-i", RTSP_URL, "-f", fileFormat, destFilePath);
  
  Process processToExecute = builder.start();

  I want to close the process before it completes its execution. So, If I run this FFMPEG command directly in windows CMD and then press ’CTRL+C’ after 5 seconds then process get terminates with status ’2’. And I can play the media file created so far.

  So, If I do the same operation in my Java Application using :

   process.destroy(); //I call this method after 5 sec

  I get the status code ’1’ which means abnormal termination. I get the status by the following way :

   processToExecute.destroy();
  
   processToExecute.exitValue(); //This return me status '1'

  And I can’t play the media file and I think this is due to the abnormal termination of the process.

  So how I can terminate the process created using ProcessBuilder in the same way we do in CMD with (CTRL+C) so that I may play the created media file ?

  I want to terminate process (created using ProcessBuilder) in Java Application with status code of ’2’ that I get when I terminate process using CMD.

  EDIT#01 : --- Sharing Findings

  So, when I try to delete that file once app terminates, I get the following error :

  The Action Can't be Performed Because File is Opened in FFMPEG.exe

  Which means that process is not terminating the command it is executing. That command still has occupied this file that’s why I am not getting able to play it. Process gets terminate when I call :

   processToExecute.destroy();

  But, the task it is performing (that is execution of a command) is still active. Strange !!!!

  EDIT#02 : Sharing Ultimate Reason

  Actually If I directly press ’CTRL+C’ or ’q’ in cmd when process is running then it terminates the process successfully and this process is no more visible in the currently executing processes lists.

  And Programatically when I call method :

  cmd> processToExecute.destroy();

  It terminates the process but when I see the list of currently executing processes I can still see them over there.

  And same scenario exists If I try to terminate this process using ’taskkill’ or ’kill’ command in another CMD by specifying their’s name or pid that still process terminates abnormally.

  P.S. I use the following command to see the running processes :

  tasklist

  So from this it proves that destroy() method from Application and ’taskkill or kill’ command from another CMD is not terminating the process normally that pressing ’CTRL+C’ and ’q’ does.
