+# Prontuario Git per installare/aggiornare Warehouse da remoto
+
+Repository Gitea:
+
+    https://gitea.alessandrobonvicini.it/administrator/ware_house.git
+
+Cartella consigliata sul PC di produzione:
+
+    C:\flywms
+
+Ramo principale da usare in produzione:
+
+    main
+
+Ultimo tag stabile al momento della stesura:
+
+    alpha7-stabilizzazione-non-scaffalate
+
+
+1. Prima installazione su PC nuovo
+----------------------------------
+
+Aprire PowerShell nella macchina di produzione ed eseguire:
+
+    cd C:\
+    git clone https://gitea.alessandrobonvicini.it/administrator/ware_house.git C:\flywms
+    cd C:\flywms
+    git switch main
+    git pull origin main
+
+Installare le dipendenze Python:
+
+    python -m pip install --upgrade pip
+    python -m pip install -r requirements.txt
+
+Avvio applicazione desktop:
+
+    python main.py
+
+Oppure senza finestra console:
+
+    pythonw warehouse.pyw
+
+Avvio applicazione barcode:
+
+    python barcode_client.py
+
+Oppure senza finestra console:
+
+    pythonw barcode.pyw
+
+
+2. Aggiornare un'installazione gia' esistente
+--------------------------------------------
+
+Sul PC di produzione:
+
+    cd C:\flywms
+    git fetch --all --tags
+    git switch main
+    git pull origin main
+    python -m pip install -r requirements.txt
+
+Poi rilanciare l'applicazione.
+
+
+2.bis Aggiornare produzione dopo merge su main gia' fatto
+---------------------------------------------------------
+
+Questo e' il caso piu' normale:
+
+    - sul PC di sviluppo hai gia' fatto merge del ramo di lavoro dentro main;
+    - hai gia' fatto push su Gitea;
+    - sul PC di produzione devi solo scaricare l'ultima versione ufficiale.
+
+Sul PC di produzione eseguire:
+
+    cd C:\flywms
+    git fetch --all --tags
+    git switch main
+    git pull origin main
+    python -m pip install -r requirements.txt
+
+Poi chiudere e riaprire l'applicazione.
+
+Controllo consigliato dopo l'aggiornamento:
+
+    git log --oneline --decorate -3
+    git describe --tags --abbrev=0 main
+
+
+3. Controllare che versione/tag si sta usando
+---------------------------------------------
+
+Dentro C:\flywms:
+
+    git status
+    git log --oneline --decorate -5
+
+Vedere l'ultimo tag raggiungibile da main:
+
+    git describe --tags --abbrev=0 main
+
+Vedere tutti i tag, dal piu' recente:
+
+    git tag --sort=-creatordate
+
+Vedere graficamente branch, commit e tag:
+
+    git log --oneline --decorate --graph --all -20
+
+
+4. Installare esattamente una versione taggata
+---------------------------------------------
+
+Usare questa modalita' quando si vuole installare una fotografia precisa e non
+necessariamente l'ultima versione di main.
+
+Esempio:
+
+    cd C:\
+    git clone --branch alpha7-stabilizzazione-non-scaffalate https://gitea.alessandrobonvicini.it/administrator/ware_house.git C:\flywms_alpha7
+
+Nota:
+
+    Un tag e' una fotografia ferma. Non avanza con git pull come un branch.
+    Per produzione ordinaria e' piu' comodo usare main.
+
+
+5. Portare l'ultimo sviluppo dentro main
+---------------------------------------
+
+Da fare sulla macchina di sviluppo, non sul PC di produzione.
+
+Se l'ultima versione buona e' su sviluppo3 e vuoi renderla ufficiale su main:
+
+    cd C:\devel\python\ware_house
+    git fetch --all --tags
+    git status
+    git switch main
+    git pull origin main
+    git merge sviluppo3
+    git push origin main
+
+Se vuoi anche creare un tag stabile:
+
+    git tag nome-del-tag
+    git push origin nome-del-tag
+
+Esempio:
+
+    git tag alpha8-nome-breve-della-modifica
+    git push origin alpha8-nome-breve-della-modifica
+
+
+6. Se il PC di produzione ha modifiche locali
+---------------------------------------------
+
+Prima di aggiornare controllare:
+
+    cd C:\flywms
+    git status
+
+Se compaiono file modificati che non devono essere conservati, NON fare comandi
+distruttivi senza sapere cosa sono. Prima copiare o rinominare i file modificati.
+
+File che normalmente NON devono essere messi nel repository:
+
+    db_connection.json
+    *.log
+    __pycache__
+    *.pyc
+    *.zip
+
+
+7. Script SQL
+-------------
+
+Gli script SQL sono nel repository e vanno lanciati in SSMS solo quando serve
+preparare o aggiornare il database per le funzioni Python.
+
+Patch principali:
+
+    apply_python_parallel_pickinglist_patch.sql
+    apply_python_pickinglist_history_views.sql
+    apply_online_history_forms_patch.sql
+
+Rollback principali:
+
+    rollback_python_parallel_pickinglist_patch.sql
+    rollback_python_pickinglist_history_views.sql
+    rollback_online_history_forms_patch.sql
+
+Nota:
+
+    Prima di lanciare patch SQL in produzione, fare sempre backup o snapshot del
+    database, oppure verificare di avere una procedura di rollback sicura.
+
+
+8. Comando rapido piu' usato
+----------------------------
+
+Aggiornamento standard del PC di produzione:
+
+    cd C:\flywms
+    git fetch --all --tags
+    git switch main
+    git pull origin main
+    python -m pip install -r requirements.txt
+	
+
+9. Per vedere cosa ho installato
+------------------------------------------------------
+	git log --oneline --decorate -3
+	git describe --tags --abbrev=0 main
+
+
+10. Salvare questo prontuario su Gitea
+-------------------------------------
+
+Da fare sul PC di sviluppo, dentro la cartella del repository:
+
+    cd C:\devel\python\ware_house
+    git status
+    git add comandi_git_per_installare.txt
+    git commit -m "Aggiungi prontuario Git per installazione remota"
+    git push origin main
+
+Dopo il push, il file sara' disponibile anche sui PC di produzione al prossimo:
+
+    cd C:\flywms
+    git pull origin main
+
+
+11. Aggiornare il prontuario se lo modifico in locale
+----------------------------------------------------
+
+Se modifichi questo file sul PC di sviluppo e vuoi sincronizzarlo su Gitea:
+
+    cd C:\devel\python\ware_house
+    git status
+    git diff -- comandi_git_per_installare.txt
+    git add comandi_git_per_installare.txt
+    git commit -m "Aggiorna prontuario Git installazione"
+    git push origin main
+
+Se invece lo hai modificato su un PC di produzione e vuoi prima recuperare
+eventuali aggiornamenti online:
+
+    cd C:\flywms
+    git status
+    git pull origin main
+
+Se Git segnala conflitti, fermarsi e risolverli prima di rilanciare
+l'applicazione. Per evitare confusione, e' meglio modificare questo prontuario
+solo sul PC di sviluppo e poi fare push su Gitea.
