#  Script to automate updating a staged WordPress site from a local dev environment and clear PageSpeed
#  and NGiNX fastcgi caches.  Skips uploading node_modules.
#
#  1) Update WordPress (Understrap) version in style.css so browsers will refresh the new version
#  2) use lftp w/ sftp to reverse mirror files w/ 20 parallel connections (FAST.)
#  3) use SSH to remotely execute a cache clearing script

# Update these...
REMOTEUSER=ubuntu 
REMOTEHOST=stage.remotehost.com
PRIVKEY=REMOTEHOST.pem

# And these...
# Path to the WordPress stylesheet w/ Version # in it
STYLEPATH="/Users/larry/Development/websites/remotehost.com/wordpress/wp-content/themes/remotehost/style.css"
# Local source directory
SOURCEDIR="/Users/larry/Development/websites/remotehost.com/wordpress"
# Remote Destination Directory
DESTDIR="/var/www/html"

# Onwards to the good stuff... no need to update anything else
perl -i -pe 's/^\sVersion:\s+\d+\.\d+\.\K(\d+)/ $1+1 /e' ${STYLEPATH}
lftp sftp://${REMOTEUSER}:@${REMOTEHOST} -e 'set sftp:connect-program "ssh -i ~/.ssh/'${PRIVKEY}'"; mirror -c -e -R --parallel=20  --verbose "'${SOURCEDIR}'" "'${DESTDIR}'" --exclude node_modules/;quit;'
ssh -t ${REMOTEUSER}@${REMOTEHOST} -i ~/.ssh/${PRIVKEY} "sudo -s; rm -rf /etc/nginx/cache; rm -rf /var/ngx_pagespeed_cache/*"
