+#           the repository (without checking the ISMAS-trigger (WAIT-)button.
+VERSION="1.3.14"
+# 1.3.14:   Add additional check for sanity of customer repository using
+#           "git fsck".
+#           Stream-lined code of update process: massive refactoring.
+#           Added functionality: If WAIT button is not active, then an existing
+#           customer repository will be repaired, or a not existing repository
+#           will be cloned. The process stops then.
+#           However, if the WAIT button is active, the at least the commands in
+#           opkg_commands will be executed. Changed files in the customer
+#           repository will be worked on: tariff-files will be synced with the
+#           local filesystem, json-files will be downloaded to firmware.
+#           The device-controller firmware will be handled in a later version.
+
+# PLANNED TODOS:
+#   1:  Das Repository wird repariert bwz. neu geklont. Unabhaengig vom WAIT.
+#   2:  Wenn der WAIT-Button aktiv ist, dann wird ein Repository repariert (neu
+#       geklont), aber zusaetzlich werden alle verfuegbaren Dateien als neu
+#       angesehen und die entsprechenden Aktionen durchgefuehrt: tariff-files
+#       spiegeln, json-files laden und dc laden. Also VORSICHT: das repository
+#       muss in diesem fall wirklich in ordnung sein.
+#   3:  Wurde keine Datei geaendert, kein initiales Clone und der WAIT-button
+#       nicht aktiv, so (passiert natuerlich nichts) kann man davon ausgehen,
+#       dass es sich um ein automatisches Update handelt. Dann koennte man im
+#       ISMAS eine entsprechende Meldung anzeigen als Teil von SEND-LAST-VERSION.
+#       Wenn der WAIT-button aktiv ist, dann werden zumindest die opkg-commands
+#       ausgefuehrt.
+#   4:  rsync: immer alle Dateien soiegeln (bis auf opkg-commands)
+#   5:  Falls das Tool mal abstuerzt, dann einen Signal-Handler (fuer TERM)
+#       installieren, sodass zumnidest SEND-LASt-VERSION mit rausgeht.
+#   6:  rsync: explizites Binary, nicht das in busybox enthaltene.

+    Zunaechst wir immer nachgesehen, ob das Repository bereits geklont wurde.
+    Wenn nein, dann wird geklont. Im Master-Branch befinden sich Dateinen, die
+    in allen anderen Branches gemeinsam genutzt werden. Das sollte wohl auf
+    jeden Fall fuer den DeviceController gelten.
+1:
+    Anfrage bei ISMAS ob neue Daten da sind. Hier faengt die ganze Sache an.
+    Da man nicht weiss, on ISMAS ueberhaupt antworten wird braucht es einen
+    Timer. Man kann die Sache dann auch gleich mehrfach versuchen.
+
+    Die Anfrage geht also per Signal an den Apism-Client. Im Signal wird der
+    Zustand mitgegeben:
+
+        ISMAS_UPDATE_REQUEST_PENDING
+
+    und im Slot dann entsprechend uebernommen. Der Timer sollte nicht im Worker
+    stehen, sondern im Apism-Client. Der Worker sollte damit nicht belastet
+    sein. Der wird dann vom Apism-Client entsprechend benachrichtigt.
+
+        ISMAS_UPDATE_REQUEST_FAILURE
+            ISMAS_UPDATE_REQUEST_TIMEOUT
+        ISMAS_UPDATE_REQUEST_SUCCESS
+
+    Im 1./2.Fall wird dann ein Fehlerhandling durchgefuehrt. Insbesondere
+    wird Apism ueber den DB-Kanal darueber informiert (U0003). Am Ende wie
+    dann wie immer SendCmdVersion und beenden der Applikation.
+
+    Im Erfolgsfall muss in der Antwort der Branch enthalten sein, fuer den das
+    Update durchgefuhrt werden soll. Das ist auch bereits so (Location).
+
+    Ein Sonderfall waere der -m-Modus, da hier niemand auf der ISMAS-Seite
+    aktiv eingreift. Hier braucht es dann einen Ubergabeparameter an 
+    ATBUpdateTool: --branch-name
+
+    Normalfall ist aber die Aktivierung via ISMAS. Dann muss der in der Antwort
+    enthaltene Branch zunaechst ausgecheckt werden.
+2: 
+    Dazu wird ein entsprechendes Signal an den GitClient gesandet.
+        
+        GIT_CHECKOUT_BRANCH_REQUEST
+
+    Der GitClient sieht jetzt erstmal nach, ob es diesen Branch ueberhaupt
+    gibt.
+
+        Falls nein:    
+
+        GIT_CHECKOUT_BRANCH_REQUEST_FAILURE
+            BRANCH_NOT_EXIST
+ 
+        Falls ja:
+            der GitClient versucht nun den Branch auszuchecken. 
+            Geht das gut?
+            Falls nein:
+
+                GIT_CHECKOUT_BRANCH_REQUEST_FAILURE
+                    BRANCH_CHECKOUT_ERROR
+
+            Falls ja:
+                GIT_CHECKOUT_BRANCH_REQUEST_SUCCESS
+                    -> eventl. koennte man den Namen des Branches mitgeben
+
+
+        Signal an den Worker. Im entsprechenden Slot wird jetzt der eigentliche
+        UpdateProzess angeworfen.
+ 3:
+    Mittels git fetch werden jetzt die Aenderungen ermittelt.
+
+        GIT_FETCH_UPDATES_REQUEST
+        
+        GIT_FETCH_UPDATES_REQUEST_FAILURE
+            -> Worker informieren damit Fehlerbehandlung aktiviert wird
+        GIT_FETCH_UPDATES_REQUEST_SUCCESS
+
+        GIT_DIFF_UPDATES
+
+        Die Liste der geaenderten Dateien geht an den Worker. Der kann jetzt
+        noch Test machen, ob das Sinn macht. Evtl. eine Statusmeldung ausgeben
+        drueber was gleich passieren wird.
+4:
+    Mittels git merge/pull werden nun die Dateien tatsaechlich im Branch 
+    aktualisiert.
+
+        GIT_PULL_UPDATES_REQUEST
+        GIT_PULL_UPDATES_REQUEST_FAILURE
+            -> Worker informieren damit Fehlerbehandlung aktiviert wird
+        GIT_PULL_UPDATES_REQUEST_SUCCESS
+            -> Worker informieren
+
+    Sind die Daten vorhanden, dann werden sie mittels rsync ins Dateisystem
+    kopiert.
+
+        RSYNC_UPDATES 
+        RSYNC_UPDATES_FAILURE
+        RSYNC_UPDATES_SUCCESS
+
+    Fuer jede kopierte Datei geht eine Nachricht raus ans ISMAS.
+5:
+    Sind die Daten dann kopiert, so werden sie auf den DC kopiert (falls
+    notwendig): hier gehen dann wieder Nachrichten an ISMAS raus:
+
+        DC_UPDATE 
+        DC_UPDATE_FAILURE
+        DC_UPDATE_SUCCESS
+
+        JSON_UPDATE

+\title{Update PTU}
+\author{Gerhard Hoffmann}
+\date{\today}
+
+\begin{document}
+\maketitle
+% \chapter{Introduction}
+\section{Motivation}
+
+The two main components of a PSA are
+\begin{itemize}
+    \item PTU software.
+    \item Device controller (DC) firmware.
+\end{itemize}
+
+While the DC firmware is basically the same for each PSA (even for different
+customers), the PTU software is highly dependent on customer requirements.\par
+Hence, each customer is assigned an own git-repository, which will be loaded
+("cloned") on the PSA when configuring the machine for the first time.\par
+Two special tools, the {\bf UpdateController} (a \href{https://doc.qt.io/qt-5/}{Qt}
+binary [{\bf \nameref{UpdateTool}}]) and the {\bf UpdateScript}
+(a \href{https://www.gnu.org/software/bash/manual/bash.html}{bash}
+script [{\bf \nameref{UpdateScript}}]), work together to finish a PSA installation.\par 
+    
+\section{PSA: Initial configuration}
+
+For the initial configuration, a PSA loads a customer-specific git-repository,
+which structure is detailed below [{\bf \nameref{repostructure}}].\par
+The "git clone" for the repository is done by the UpdateScript [{\bf \nameref{UpdateScript}}].
+It updates the file
+\begin{center}
+    \fbox{
+        /opt/app/tools/atbupdate/update\_log.csv
+    }
+\end{center}
+which will be interpreted by the UpdateController [{\bf \nameref{UpdateTool}}].
+The structure of [{\bf \nameref{updatelogcsv}}] is detailed below.\par
+Each line of update\_log.csv represents a command for the UpdateController,
+which will either download certain files to the DC or execute some
+\href{https://openwrt.org/docs/guide-user/additional-software/opkg}{opkg}
+commands [{\bf \nameref{opkg}}].
+        
+\section{PSA: Update}
+   
+The update of a PSA is basically managed by \href{https://git-scm.com/}{git}, a
+free and open source distributed version control system. Like many other Version
+Control Systems, git has a way to fire off custom scripts when certain important
+actions occur, so-called \href{https://git-scm.com/book/en/v2/Customizing-Git-Git-Hooks}{hooks}.
+The hooks used for a PSA update are called {\bf post-checkout} and {\bf post-merge}.\par
+The post-checkout hook is called when checking out some branch of the customer-repository
+(for instance when cloning the customer repository for the first time). In contrast,
+the post-merge hook is called when a \href{https://www.git-scm.com/docs/git-pull}{git pull}
+operation has been issued (more precisely, a \href {https://www.git-scm.com/docs/git-fetch}{git-fetch}
+followed by a \href{https://www.git-scm.com/docs/git-merge}{git-merge}).\par
+Both hooks update the file [{\bf \nameref{updatelogcsv}}], which is interpreted
+by the UpdateController in a second step.
+    
+% \chapter{Update-Tool "up\_dev\_ctrl"}
+    \section{up\_dev\_ctrl}
+    \label{UpdateTool}
+
+        The update-tool is a Qt binary ("up\_dev\_ctrl") and called by the
+        system-controller application. It is installed under
+        \begin{center}
+            \fbox{
+                /opt/app/tools/atbupdate/up\_dev\_ctrl
+            }
+        \end{center}
+
+        and has two responsibilities:
+        \begin{itemize}
+            \item Call update-script "update\_psa".
+            \item Update the device controller firmware.
+        \end{itemize}
+    \subsection{Calling the update-script "update\_psa"}
+        The update-script "update\_psa" is about executing all git-commands
+        necessary to clone and pull a customer repository.

+    \label{UpdateScript}
+
+    Inside of such a
+        repository, there are at least the following directories:

+           \item {\bf etc} 
+           \item {\bf etc/dc}\newline 
+                Contains the device controller firmware as binary file.
+           \item {\bf etc/psa\_config}\newline
+                Contains the printer template files (JSON).
+           \item {\bf etc/psa\_tariff}\newline
+                Contains the tariff files (JSON).
+           \item {\bf etc/psa\_update}\newline

+    /*  Blobless clone
+        ==============
+
+        When using the --filter=blob:none option, the initial git clone will
+        download all reachable commits and trees, and only download the blobs
+        for commits when you do a git checkout. This includes the first checkout
+        inside the git clone operation.
+
+        The important thing to notice is that we have a copy of every blob at
+        HEAD but the blobs in the history are not present. If your repository
+        has a deep history full of large blobs, then this option can
+        significantly reduce your git clone times. The commit and tree data is
+        still present, so any subsequent git checkout only needs to download
+        the missing blobs. The Git client knows how to batch these requests to
+        ask the server only for the missing blobs.
+
+        Further, when running git fetch in a blobless clone, the server only
+        sends the new commits and trees. The new blobs are downloaded only
+        after a git checkout. Note that git pull runs git fetch and then git
+        merge, so it will download the necessary blobs during the git merge
+        command.
+
+        When using a blobless clone, you will trigger a blob download whenever
+        you need the contents of a file, but you will not need one if you only
+        need the OID (object-id) of a file. This means that git log can detect
+        which commits changed a given path without needing to download extra
+        data.
+
+        This means that blobless clones can perform commands like git
+        merge-base, git log, or even git log -- <path> with the same performance
+        as a full clone.
+
+        Commands like git diff or git blame <path> require the contents of the
+        paths to compute diffs, so these will trigger blob downloads the first
+        time they are run. However, the good news is that after that you will
+        have those blobs in your repository and do not need to download them a
+        second time. Most developers only need to run git blame on a small
+        number of files, so this tradeoff of a slightly slower git blame command
+        is worth the faster clone and fetch times.
+
+        Note: git v2.18 does not support treeless clones: --filter=tree:0.
