### Settings are automatically loaded as bash variables
|
|
### in every app script context, therefore typically these will exist:
|
|
### - $domain
|
|
### - $path
|
|
### - $language
|
|
### - $install_dir
|
|
### - $port
|
|
### ...
|
|
|
|
### In the context of upgrade,
|
|
### - resources are automatically provisioned / updated / deleted (depending on existing resources)
|
|
### - a safety backup is automatically created by the core and will be restored if the upgrade fails
|
|
|
|
### This variable describes which upgrade type is occurring, allowing the script to handle different modes:
|
|
### - UPGRADE_PACKAGE if only the YunoHost package has changed
|
|
### - UPGRADE_APP if the upstream app version has changed
|
|
### If your package needs to handle other things, like same-version upgrades or downgrades, please
|
|
### check out the $YNH_APP_UPGRADE_TYPE variable that can contain DOWNGRADE and UPGRADE_SAME too.

### N.B. : the following setting migration snippets are provided as *EXAMPLES*

|

### Same as during install
|
|

|
|
### The file will automatically be backed-up if it's found to be manually modified (because
|
|
### ynh_add_config keeps track of the file's checksum)

|
# FIXME: this should be handled by the core in the future
|
|
### You may need to use chmod 600 instead of 400,
|
|
### for example if the app is expected to be able to modify its own config
|
|
chmod 400 "$install_dir/some_config_file"
|
|
chown "$app:$app" "$install_dir/some_config_file"
|
|
|
|
### For more complex cases where you want to replace stuff using regexes,
|
|
### you shoud rely on ynh_replace_string (which is basically a wrapper for sed)
|
|
### When doing so, you also need to manually call ynh_store_file_checksum
|
|
###
|
|
### ynh_replace_string --match_string="match_string" --replace_string="replace_string" --target_file="$install_dir/some_config_file"
