# ### Installing Rainloop

# Rainloop's webpage (http://www.rainloop.net/downloads/) does not easily	#
# list versions as the need for VERSION_FILENAME below. 			#

# 
# Dependancies are from Roundcube, not all may be needed for Rainloop		#

# We used to install Roundcube from Ubuntu, without triggering the dependencies #NODOC

# Now that we're beyond that, get rid of those debs before installing from source. #NODOC
apt-get purge -qq -y roundcube* #NODOC

# Install Roundcube from source if it is not already present or if it is out of date.
# Combine the Roundcube version number with the commit hash of vacation_sieve to track

# ### Configuring Rainloop

# Create a configuration file.
#

# Some application paths are not created until the application is launched
# this should include the internal process it has when upgrading between versions

# Fix permissions
find /usr/local/lib/rainloop -type d -exec chmod 755 {} \;
find /usr/local/lib/rainloop -type f -exec chmod 644 {} \;
chown -R www-data:www-data /usr/local/lib/rainloop

# Fixing permissions needs to happen first or else curl gets
# this error: [105] Missing version directory

curl -s -L https://$PRIMARY_HOSTNAME/mail/ > /dev/null


# Set customized configuration
# Rainloop has a default password set, not sure yet how to integrate with userlist
# for now we should change it from the default
# Methods for changing password: https://github.com/RainLoop/rainloop-webmail/issues/28
#
# Untested: edit admin_password = "????" below
#
#	or use the Rainloop API:
#	<?php
#
#	$_ENV['RAINLOOP_INCLUDE_AS_API'] = true;
#	include '<path-to-rainloop-folder>/index.php';
#
#	$oConfig = \RainLoop\Api::Config();
#	$oConfig->SetPassword('pa$$wOrd');
#	echo $oConfig->Save() ? 'Done' : 'Error';
#
#	?>

# This can be improved, need to take a look at editconf.py for multi line edits as
# there are multiple "enable = On" but we should only edit them per category.
