# EXPERIMENTAL HELPERS
#=================================================
# Make the main steps to migrate an app to its fork.
#
# This helper has to be used for an app which needs to migrate to a new name or a new fork
# (like owncloud to nextcloud or zerobin to privatebin).
#
# This helper will move the files of an app to its new name
# or recreate the things it can't move.
#
# To specify which files it has to move, you have to create a "migration file", stored in ../conf
# This file is a simple list of each file it has to move,
# except that file names must reference the $app variable instead of the real name of the app,
# and every instance-specific variables (like $domain).
# $app is especially important because it's this variable which will be used to identify the old place and the new one for each file.
#
# If a database exists for this app, it will be dumped and then imported in a newly created database, with a new name and new user.
# Don't forget you have to then apply these changes to application-specific settings (depends on the packaged application)
#
# Same things for an existing user, a new one will be created.
# But the old one can't be removed unless it's not used. See below.
#
# If you have some dependencies for your app, it's possible to change the fake debian package which manages them.
# You have to fill the $pkg_dependencies variable, and then a new fake package will be created and installed,
# and the old one will be removed.
# If you don't have a $pkg_dependencies variable, the helper can't know what the app dependencies are.
#
# The app settings.yml will be modified as follows:
# - finalpath will be changed according to the new name (but only if the existing $final_path contains the old app name)
# - The checksums of php-fpm and nginx config files will be updated too.
# - If there is a $db_name value, it will be changed.
# - And, of course, the ID will be changed to the new name too.
#
# Finally, the $app variable will take the value of the new name.
# The helper will set the $migration_process variable to 1 if a migration has been successfully handled.
#
# You have to handle by yourself all the migrations not done by this helper, like configuration or special values in settings.yml
# Also, at the end of the upgrade script, you have to add a post_migration script to handle all the things the helper can't do during YunoHost upgrade (mostly for permission reasons),
# especially remove the old user, move some hooks and remove the old configuration directory
# To launch this script, you have to move it elsewhere and start it after the upgrade script.

# `(cd /tmp; echo "/tmp/$script_post_migration" | at now + 2 minutes)`

#
# | arg: -u, --usage - Expected usage of the service (low/medium/high).
# low - Personal usage, behind the sso.
# medium - Low usage, few people or/and publicly accessible.
# high - High usage, frequently visited website.
#
# | arg: -p, --print - Print the result
#
#
#
# The footprint of the service will be used to defined the maximum footprint we can allow, which is half the maximum RAM.
# So it will be used to defined 'pm.max_children'
# A lower value for the footprint will allow more children for 'pm.max_children'. And so for
# 'pm.start_servers', 'pm.min_spare_servers' and 'pm.max_spare_servers' which are defined from the
# value of 'pm.max_children'
# NOTE: 'pm.max_children' can't exceed 4 times the number of processor's cores.
#
# The usage value will defined the way php will handle the children for the pool.
# A value set as 'low' will set the process manager to 'ondemand'. Children will start only if the
# service is used, otherwise no child will stay alive. This config gives the lower footprint when the
# service is idle. But will use more proc since it has to start a child as soon it's used.
# Set as 'medium', the process manager will be at dynamic. If the service is idle, a number of children
# equal to pm.min_spare_servers will stay alive. So the service can be quick to answer to any request.
# The number of children can grow if needed. The footprint can stay low if the service is idle, but
# not null. The impact on the proc is a little bit less than 'ondemand' as there's always a few
# children already available.
# Set as 'high', the process manager will be set at 'static'. There will be always as many children as
# 'pm.max_children', the footprint is important (but will be set as maximum a quarter of the maximum
# RAM) but the impact on the proc is lower. The service will be quick to answer as there's always many

# patched version of ynh_install_app_dependencies to be used with ynh_add_app_dependencies
# Define and install dependencies with a equivs control file
# This helper can/should only be called once per app
#
# usage: ynh_install_app_dependencies dep [dep [...]]
# | arg: dep - the package name to install in dependence
# You can give a choice between some package with this syntax : "dep1|dep2"
# Example : ynh_install_app_dependencies dep1 dep2 "dep3|dep4|dep5"
# This mean in the dependence tree : dep1 & dep2 & (dep3 | dep4 | dep5)
#
# Requires YunoHost version 2.6.4 or higher.

# [^(\<=\>] ignore if it begins by ( or < = >. To not apply twice.

# \+ matches one or more occurence of the previous characters, for >= or >>.
# [^,]\+ matches all characters except ','
# Ex: package>=1.0 will be replaced by package (>= 1.0)
