TESM 2.0.0 -- Neubau
Vollstaendiger Neubau der Anwendung. Der vorherige Stand bleibt unveraendert im Zweig SONNET5 erhalten. Aufbau: apps/tesm (Anwendung), packages/tesm-core (gemeinsamer Kern), packages/tesm-licensing (Lizenzprotokoll), deploy (Installation, systemd, privilegierter Helfer), docs, tests. Der Lizenzserver liegt in seinem eigenen Repository; beide Repositorien bringen die gemeinsamen Pakete mit, damit sich jedes allein installieren laesst. Die wichtigsten Unterschiede zum Vorgaenger, jeweils an der Stelle im Code kommentiert, an der der Fehler entstanden ist: * Der Webprozess laeuft unprivilegiert. Alles, was Root braucht, geht ueber einen einzigen Helfer mit Positivlisten fuer jedes Argument. * CSRF-Schutz ueberhaupt -- der Vorgaenger hatte keinen. * Rechte werden serverseitig geprueft, nicht nur im Template ausgeblendet. * Die nginx-Site wird bei jedem Lauf inhaltlich verglichen und erneuert. * Jede erzeugte Konfiguration wird vor dem Uebernehmen geprueft (nginx, Kea). * Kein Hostname im Lizenz-Fingerabdruck. * Zwei Installationen auf einem Host stoeren sich nicht (eigener SITE_KEY). * Verschachtelte Datenbankverbindungen sind ein Fehler, kein Deadlock.
