Warming up WordPress cache, HHVM and testing blog pages

If you are minifying scripts and css files using a caching plugin or using FastCGI cache then you might need to warmup your blog after purging your cache. This is a simple warm up cli script for WordPress to initiate cache or HHVM HHBC and making sure all pages/posts do not have errors. Additionally the script creates a urllist.txt file that you can use with siege to test load your server.

Custom validation messages for sails js

//in api/models/User.js
function validationError(invalidAttributes, status, message) {
  var WLValidationError = require('../../node_modules/sails/node_modules/waterline/lib/waterline/error/WLValidationError.js');
  return new WLValidationError({
      invalidAttributes: invalidAttributes,
      status: status,
      message: message
var User = {
  attributes: {
  ownValidate:: function (values, update, cb) {
    //example of not allowed param on update
    //if it is an update then do not allow email param
    if (update && {
      return cb(validationError({
        email: [
            message: 'Email is not allowed for updates.'
      }, 400 /*status*/));
    sails.models['user'].findOne( (err, user) {
      if (err) return cb(err);
      if (user) {

Use mysqldump to create separate files and directories for databases and tables

The script creates separate directory for every database and bz2 files for every table inside that database.


#edit these


echo - Dumping DB structure "$MYSQLDIR"/all.bz2 
$MYSQLDUMP --user=$USER --password=$PASSWORD -d --all-databases | bzip2 > "$MYSQLDIR"/all.bz2 

echo - Dumping tables for each DB
databases=`$MYSQL --user=$USER --password=$PASSWORD -e "SHOW DATABASES;" | grep -Ev "(Database|information_schema)"`
for db in $databases; do
    echo - Creating "$db" DB
	mkdir $MYSQLDIR/$db
	chmod -R 777 $MYSQLDIR/$db
	for tb in `$MYSQL  --user=$USER --password=$PASSWORD -N -B -e "use $db ;show tables"`
			echo -- Creating table $tb
			$MYSQLDUMP --opt  --delayed-insert --insert-ignore --user=$USER --password=$PASSWORD $db $tb | bzip2 -c > $MYSQLDIR/$db/$tb.sql.bz2
