### If it's a multi-instance app, meaning it can be installed several times independently
### The id of the app as stated in the manifest is available as $YNH_APP_ID
### The instance number is available as $YNH_APP_INSTANCE_NUMBER (equals "1", "2", ...)
### The app instance name is available as $YNH_APP_INSTANCE_NAME
###    - the first time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample
###    - the second time the app is installed, YNH_APP_INSTANCE_NAME = ynhexample__2
###    - ynhexample__{N} for the subsequent installations, with N=3,4, ...
### The app instance name is probably what interests you most, since this is
### guaranteed to be unique. This is a good unique identifier to define installation path,
### db names, ...
app=$YNH_APP_INSTANCE_NAME

#=================================================
# CHECK IF THE APP CAN BE INSTALLED WITH THESE ARGS
#=================================================
### If the app uses nginx as web server (written in HTML/PHP in most cases), the final path should be "/var/www/$app".
### If the app provides an internal web server (or uses another application server such as uwsgi), the final path should be "/opt/yunohost/$app"
final_path=/var/www/$app
test ! -e "$final_path" || ynh_die "This path already contains a folder"

# Normalize the url path syntax
path_url=$(ynh_normalize_url_path $path_url)

# Check web path availability
ynh_webpath_available $domain $path_url
# Register (book) web path
ynh_webpath_register $app $domain $path_url

#=================================================
# STORE SETTINGS FROM MANIFEST
#=================================================
ynh_app_setting_set $app is_public $is_public
ynh_app_setting_set $app domain $domain
ynh_app_setting_set $app path $path_url


#=================================================
# DOWNLOAD, CHECK AND UNPACK SOURCE
#=================================================

### `ynh_setup_source` is used to install an app from a zip or tar.gz file,
### downloaded from an upstream source, like a git repository.
### `ynh_setup_source` use the file conf/app.src

ynh_app_setting_set $app final_path $final_path
# Download, check integrity, uncompress and patch the source from app.src
ynh_setup_source "$final_path"

#=================================================
# CREATE A MYSQL DATABASE
#=================================================

### Use these lines if you need a database for the application.
### `ynh_mysql_setup_db` will create a database, an associated user and a ramdom password.
### The password will be stored as 'mysqlpwd' into the app settings,
### and will be available as $db_pwd
### If you're not using these lines:
###		- Remove the section "BACKUP THE MYSQL DATABASE" in the backup script
###		- Remove also the section "REMOVE THE MYSQL DATABASE" in the remove script
###		- As well as the section "RESTORE THE MYSQL DATABASE" in the restore script

db_name=$(ynh_sanitize_dbid $app)
ynh_app_setting_set $app db_name $db_name
ynh_mysql_setup_db $db_name $db_name

# Adding the details of the database to the config file
ynh_replace_string "__dbuser__" "$db_name"  "../conf/config.ini.php"
ynh_replace_string "__dbpass__" "$db_pwd"   "../conf/config.ini.php"
ynh_replace_string "__dbname__" "$db_name"  "../conf/config.ini.php"

# Copy the config file to the final path
sudo cp ../conf/config.ini.php $final_path/data/.

# Load initial SQL into the new database
ynh_mysql_connect_as "$db_name" "$db_pwd" "$db_name" < "../conf/sql/webtrees.sql"

ynh_mysql_connect_as "$db_name" "$db_pwd" "$db_name" < "../conf/sql/admin.sql"

#=================================================
# NGINX CONFIGURATION
#=================================================

### `ynh_add_nginx_config` will use the file conf/nginx.conf

# Create a dedicated nginx config
ynh_add_nginx_config

#=================================================
# CREATE DEDICATED USER
#=================================================

# Create a system user
ynh_system_user_create $app

#=================================================
# PHP-FPM CONFIGURATION
#=================================================

### `ynh_add_fpm_config` is used to set up a PHP config.
### You can remove it if your app doesn't use PHP.
### `ynh_add_fpm_config` will use the files conf/php-fpm.conf and conf/php-fpm.ini
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "BACKUP THE PHP-FPM CONFIGURATION" in the backup script
###		- Remove also the section "REMOVE PHP-FPM CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE PHP-FPM CONFIGURATION" in the restore script
###		With the reload at the end of the script.
###		- And the section "PHP-FPM CONFIGURATION" in the upgrade script

# Create a dedicated php-fpm config
ynh_add_fpm_config

# SET RIGHT PERMISSION FOR APP
#=================================================

chown -R $app: $final_path
sudo chmod -R 777 $final_path/data

#=================================================
# SETUP SSOWAT
#=================================================

# Make app public if necessary
if [ $is_public -eq 1 ]
then
	# unprotected_uris allows SSO credentials to be passed anyway.
	ynh_app_setting_set $app unprotected_uris "/"
