• multiple filessystems for exams

  • option to upload squashfs/zip files detached from exam context
    • name field (ex: "Brackets v1.14.2")
    • description field (markdown) (ex: "Installation of Brackets software")
    • visibility for other teachers checkbox
  • in exam edit view: possibility to choose multiple of these files by the name field (as an exam setting that can be selected multiple times, as much as overlayfs allows)
  • order of mount?
  • in the download process, all these files are rsync to the client
  • in the mount process, these files are mounted/unzipped in the given order before that "main" squashfs/zip files are mounted over them

• squashfs

  • place version inside squashfs and check against lernstick version (also check if it's the exam version or standard version)
  • create squashfs from running ticket

• live overview

  • new URL in avahi service file
    • actionLive='glados/index.php/ticket/live/{token}'

• locking

  • locking screen in markdown
  • lock keyboard and mouse

• misc

  • "new activity; click to reload" on all tabs in the ticket view
  • move expert settings to the client
  • models/Daemon.php rules -> maybe truncate a too long state/description
  • generally: remove save(false); statements, they cause crashes
  • put .Keylogger path to exclude_list in backupController
  • welcome to exam message in wxbrowser
  • Version conflict in log/history/activities
  • In google chrome settings->Login hint preview not visible
  • corporate identity: possibility to write text/logo in front page + colors of theme?
  • "log/view/all" permission missing when as admin looking at a log of another users ticket
  • remove download_state column in table. Has anyways no meaning anymore

• daemons

  • remove onStart and onStop from ActiveEventField (only used in /views/daemon/index.php)
  • refactor daemon view
  • have a look at https://github.com/yiisoft/yii2-queue
  • use mutex to accuire a lock (locking also works via DB), see https://www.yiiframework.com/doc/api/2.0/yii-mutex-mysqlmutex
    • mysqlMutex uses mysql db to get a lock "SELECT GET_LOCK(name)", see https://mariadb.com/kb/en/get_lock/
    • fileMutex uses flock(), but it resticted to being local (same machine)
    • needs component config in console.php (see https://www.yiiframework.com/doc/api/2.0/yii-mutex-mysqlmutex)
    • remove fields from table ticket:
      • backup_lock
      • restore_lock
      • download_lock
    • getNextItem() in daemons should then not query ->one(), instead:
      • query->all()
      • loop through models and try to accuire lock via Yii::$app->mutex->acquire('nameOfLock')
      • return first model that evaluates true
      • if all models evaluate to false -> return null
