### `ynh_replace_string` is used to replace a string in a file.
### (It's compatible with sed regular expressions syntax)
ynh_replace_string "__PORT__"       "$port"            "../conf/squid.conf"
cp -f "../conf/squid.conf" "/etc/squid3/squid.conf"


#=================================================
# SPECIFIC UPGRADE

### Verify the checksum of a file, stored by `ynh_store_file_checksum` in the install script.
### And create a backup of this file if the checksum is different. So the file will be backed up if the admin had modified it.
ynh_backup_if_checksum_is_different "/etc/squid3/squid.conf"
# Recalculate and store the checksum of the file for the next upgrade.
ynh_store_file_checksum "/etc/squid3/squid.conf"

#=================================================
# ADVERTISE SERVICE IN ADMIN PANEL
#=================================================

### `yunohost service add` is a CLI yunohost command to add a service in the admin panel.
### You'll find the service in the 'services' section of YunoHost admin panel.
### This CLI command would be useless if the app does not have any services (systemd or sysvinit)
### If you're not using these lines:
###		- You can remove these files in conf/.
###		- Remove the section "REMOVE SERVICE FROM ADMIN PANEL" in the remove script
###		- As well as the section ADVERTISE SERVICE IN ADMIN PANEL" in the restore script

yunohost service add squid3 --log "/var/log/squid3/access.log"

# RESTART SQUID'S SERVICE and SSOWATCONF
