In here we can put instructions on how to run this / any general info

to edit src:

git....
    cd ~/src ; # or wherever you want the code to live
    git clone git@192.168.0.2:photoassistant


ubuntu packages:
	sudo apt-get install -y cmake libpq-dev


AFTER a fresh ubuntu, need to remove/make a new .python env and get pip-based python packages installed into .python:
    cd ~/src/photoassistant
    rm .python
    # use a venv (to get consistent python versions with Prod container)
    python3 -m venv .python
    source ./.python/bin/activate
    pip3 install -r requirements.txt
    
upstream packages...
    mkdir static/upstream
    cd static/upstream
    mkdir bootstrap-4.6.0-dist
    cd bootstrap-4.6.0-dist

    mkdir css
    # for boostrap:
    wget https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/css/bootstrap.min.css

    mkdir js
    # to note we might need bootstrap.bundle.min.js if we use new features?
    wget https://cdn.jsdelivr.net/npm/bootstrap@4.6.0/dist/js/bootstrap.min.js

    # for jquery
    https://code.jquery.com/jquery-3.6.0.min.js

    # for jquery/smart context menu
    wget https://cdnjs.cloudflare.com/ajax/libs/jquery-contextmenu/2.9.2/jquery.contextMenu.css
    wget https://cdnjs.cloudflare.com/ajax/libs/jquery-contextmenu/2.9.2/jquery.contextMenu.min.js
    wget https://cdnjs.cloudflare.com/ajax/libs/jquery-contextmenu/2.9.2/jquery.contextMenu.min.js.map
    wget https://cdnjs.cloudflare.com/ajax/libs/jquery-contextmenu/2.9.2/jquery.ui.position.min.js

### I tried to update via pip3, with this:
sudo apt-get install libcairo2-dev libjpeg-dev libgif-dev libgirepository1.0-dev libcups2-dev
pip3 list | tail -n +3 |   grep -v mysqlclient |  grep -v duplicity | grep -v gpg | awk ' { print $1 } ' | xargs pip3 install --upgrade

To run debug version of web server (gunicorn deprecates FLASK_ENV, so co-exist for now):

    # flask 2.2.2+ (in venv .python)
    FLASK_APP=main ENV=development ./.python/bin/flask --debug run --host=192.168.0.2

to run prod version of web server:
    gunicorn --bind="192.168.0.2:5000" --threads=2 --workers=2 main:app

Also have to run the job manager for jobs to work:
    ENV="development" python3 pa_job_manager.py

To rebuild DB from scratch/empty data:

    ###BE CAREFUL this completely destroys the database contents and starts from
    #scratch, when we get real data, we will instead cp a backup file not the
    #tables.sql

    ( cd /srv/docker/config/ ; sudo docker-compose  stop padb_dev ;  yes | sudo docker-compose rm padb_dev ; sudo rm -rf /srv/docker/container/padb_dev/data/ ; sudo cp /home/ddp/src/photoassistant/tables.sql /srv/docker/container/padb_dev/docker-entrypoint-initdb.d/tables.sql ; sudo docker-compose up -d padb_dev ) &

To get back a 'working' but scanned set of data:

# make a backup and store it in DB_BACKUP:

    sudo docker exec -it padb bash
        root@2881f871e1c2:/# pg_dump --user=pa pa > /docker-entrypoint-initdb.d/tables.sql
    cp /srv/docker/container/padb/docker-entrypoint-initdb.d/tables.sql /home/ddp/src/photoassistant/DB_BACKUP/
    mv /home/ddp/src/photoassistant/DB_BACKUP/tables.sql /home/ddp/src/photoassistant/DB_BACKUP/`date +%Y%m%d-tables.sql`
    gzip /home/ddp/src/photoassistant/DB_BACKUP/`date +%Y%m%d-tables.sql`
    # mv /home/ddp/src/photoassistant/DB_BACKUP/`date +%Y%m%d-tables.sql`.gz /home/ddp/src/photoassistant/DB_BACKUP/<meaningfulname>......


# start db, using new tables.sql
    DEV:
    ( cd /srv/docker/config/ ; sudo docker-compose stop padb_dev ; sudo docker-compose rm -f padb_dev ; sudo rm -rf /srv/docker/container/padb_dev/data/ ; sudo cp /home/ddp/src/photoassistant/tables.sql /srv/docker/container/padb_dev/docker-entrypoint-initdb.d/tables.sql ; sudo docker-compose up -d padb_dev  )


    ### decide what tables.sql you want, e.g.

    sudo bash
    # gunzip -c /home/ddp/src/photoassistant/DB_BACKUP/20200126-all-imported-no-duplicates.sql.gz > /srv/docker/container/padb/docker-entrypoint-initdb.d/tables.sql

    #PROD!!!!!
    ( cd /srv/docker/config/ ; sudo docker-compose  stop padb ;  yes | sudo docker-compose rm padb ; sudo rm -rf /srv/docker/container/padb/data/ ; sudo docker-compose up -d padb )

    # export just person/refimg so we don't have to recreate them by hand between refreshes of DB
    sudo docker exec -it padb bash
        # pg_dump --user=pa -a -t person -t refimg -t person_refimg_link  > /docker-entrypoint-initdb.d/users.sql

    # export all content so we can upgrade versions of postgres
    sudo docker exec -it padb bash
        # pg_dump --user=pa pa > /docker-entrypoint-initdb.d/bkup.sql
    ### check sql looks good
    sudo mv /srv/docker/container/padb/docker-entrypoint-initdb.d/bkup.sql /srv/docker/container/padb/docker-entrypoint-initdb.d/tables.sql
    sudo rm /srv/docker/container/padb/docker-entrypoint-initdb.d/users.sql
    sudo docker-compose -f /srv/docker/config/docker-compose.yaml build padb
    ( cd /srv/docker/config/ ; sudo docker-compose  stop padb ;  yes | sudo docker-compose rm padb ; sudo rm -rf /srv/docker/container/padb/data/ ; sudo docker-compose up -d padb ; sudo docker-compose restart paweb )


HANDY SQLs/commands:
# long-running AI job (in this case #46), which is not committing joblog per file, and isnt tracking counts properly (temporary bug)

sudo docker exec -it padb bash
    echo 'select * from joblog where job_id = 46;' | psql --user=pa pa | grep 'ooking for' | awk '{ print $15 } ' | sort -u | wc -l
