#=================================================
# SPECIFIC SETUP
#=================================================
# ...
#=================================================

#=================================================
# SETUP APPLICATION WITH CURL
#=================================================

### Use these lines only if the app installation needs to be finalized through
### web forms. We generally don't want to ask the final user,
### so we're going to use curl to automatically fill the fields and submit the
### forms.

# Set right permissions for curl install
chown -R $app: $final_path

# Set the app as temporarily public for curl call
ynh_script_progression --message="Configuring SSOwat..." --time --weight=1
# Making the app public for curl
ynh_permission_update --permission="main" --add="visitors"
# Reload SSOwat config
yunohost app ssowatconf

# Reload NGINX
ynh_systemd_action --service_name=nginx --action=reload

# Installation with curl
ynh_script_progression --message="Finalizing installation..." --time --weight=1
ynh_local_curl "/INSTALL_PATH" "key1=value1" "key2=value2" "key3=value3"

# Remove the public access
ynh_permission_update --permission="main" --remove="visitors"

#=================================================
# MODIFY A CONFIG FILE
#=================================================

ynh_add_config --template="../conf/common.php" --destination="$final_path/protected/config/common.php"

ynh_replace_string --match_string="match_string" --replace_string="replace_string" --target_file="$final_path/CONFIG_FILE"

#=================================================
# STORE THE CONFIG FILE CHECKSUM
#=================================================

### `ynh_store_file_checksum` is used to store the checksum of a file.
### That way, during the upgrade script, by using `ynh_backup_if_checksum_is_different`,
### you can make a backup of this file before modifying it again if the admin had modified it.

# Calculate and store the config file checksum into the app settings
ynh_store_file_checksum --file="$final_path/CONFIG_FILE"

#=================================================
# GENERIC FINALIZATION
#=================================================
# SECURE FILES AND DIRECTORIES
#=================================================

# Set permissions to app files
chown -R www-data: $final_path

#=================================================
# SETUP LOGROTATE
#=================================================
ynh_script_progression --message="Configuring log rotation..." --time --weight=1

### `ynh_use_logrotate` is used to configure a logrotate configuration for the logs of this app.
### Use this helper only if there is effectively a log file for this app.
### If you're not using this helper:
###		- Remove the section "BACKUP LOGROTATE" in the backup script
###		- Remove also the section "REMOVE LOGROTATE CONFIGURATION" in the remove script
###		- As well as the section "RESTORE THE LOGROTATE CONFIGURATION" in the restore script
###		- And the section "SETUP LOGROTATE" in the upgrade script

# Use logrotate to manage application logfile(s)
ynh_use_logrotate

#=================================================
# INTEGRATE SERVICE IN YUNOHOST
#=================================================
ynh_script_progression --message="Integrating service in YunoHost..." --time --weight=1

yunohost service add $app --description="A short description of the app" --log="/var/log/$app/$app.log"

### Additional options starting with 3.8:
###
### --needs_exposed_ports "$port" a list of ports that needs to be publicly exposed
###                               which will then be checked by YunoHost's diagnosis system
###                               (N.B. DO NOT USE THIS is the port is only internal!!!)
###
### --test_status "some command"  a custom command to check the status of the service
###                               (only relevant if 'systemctl status' doesn't do a good job)
###
### --test_conf "some command"    some command similar to "nginx -t" that validates the conf of the service
###
### Re-calling 'yunohost service add' during the upgrade script is the right way
### to proceed if you later realize that you need to enable some flags that
### weren't enabled on old installs (be careful it'll override the existing
### service though so you should re-provide all relevant flags when doing so)

#=================================================
# START SYSTEMD SERVICE
#=================================================
ynh_script_progression --message="Starting a systemd service..." --time --weight=1

### `ynh_systemd_action` is used to start a systemd service for an app.
### Only needed if you have configure a systemd service
### If you're not using these lines:
###		- Remove the section "STOP SYSTEMD SERVICE" and "START SYSTEMD SERVICE" in the backup script
###		- As well as the section "START SYSTEMD SERVICE" in the restore script
###		- As well as the section"STOP SYSTEMD SERVICE" and "START SYSTEMD SERVICE" in the upgrade script
###		- And the section "STOP SYSTEMD SERVICE" and "START SYSTEMD SERVICE" in the change_url script

# Start a systemd service
ynh_systemd_action --service_name=$app --action="start" --log_path="/var/log/$app/$app.log"

#=================================================
# SETUP FAIL2BAN
#=================================================
ynh_script_progression --message="Configuring Fail2Ban..." --time --weight=1

# Create a dedicated Fail2Ban config
ynh_add_fail2ban_config --logpath="/var/log/nginx/${domain}-error.log" --failregex="Regex to match into the log for a failed login"

#=================================================
# SETUP SSOWAT
#=================================================
ynh_script_progression --message="Configuring permissions..." --time --weight=1

# Make app public if necessary
if [ $is_public -eq 1 ]
then
	ynh_permission_update --permission="main" --add="visitors"
fi

#=================================================
# RELOAD NGINX
#=================================================
ynh_script_progression --message="Reloading NGINX web server..." --time --weight=1

ynh_systemd_action --service_name=nginx --action=reload
