Install same packages for different PHP version

This is one of the things I should have thought of a long time ago.
More times than I can count I needed to install the same (or similar) list of PHP packages for a different version (ie. installing 7.0 while keeping 5.6) So instead of manually copying over the list or guessing as to what will be installed via dependencies here’s a quick one liner. Again, it’s a “facepalm” moment here for me:

# this installs 7.1 packages from a 7.0 list
dpkg -l | grep php7 | awk '{gsub(/7\.0/,"7.1",$2); print $2}' | xargs apt install

Also on my mind: instead of a sit/stand desk, can I install a shower desk. This way I can work and take showers at the same time!

Php5{en,dis}mod mcrypt

Seriously. I’m doing too much php stuff!

Here are a few things I learned in the last couple of days:

apt-get install php5-mcrypt
dpkg -l php5-mcrypt
ii php5-mcrypt 5.4.6-0ubuntu6 amd64 MCrypt module for php5
php -m | grep -c mcrypt
php5enmod mcrypt
php -m | grep mcrypt

And to install xhgui+xhprof, follow this tutorial (README is lacking)

Reminder to self: Don’t use == for string comparison in PHP

From SO thread

You should never use == for string comparison. === is OK.

$something = 0;
echo ('password123' == $something) ? 'true' : 'false';

Just run the above code and you’ll see why.

$something = 0;
echo ('password123' === $something) ? 'true' : 'false';

The reason is that when using ‘==’ it will try to convert the string to a number, and match it!

Now where’s the emoji for facepalm?

Codeception Testing – Part 2

I’m still setting up for BDD testing. All the basics are already there (see previous post).

I spoke quickly about setting up WPBrowser: WordPress specific set of extensions for Codeception. Here’s what to do (from the Readme):

  1. Require the package in the composer.json, then run “composer update” (details)
  2. Add the WPBrowser or WPWebDriver module in tests/acceptance.suite.yml (details)

The added bonus, if you’re using PhpStorm is that you will also get the related auto-complete package. And there’s plenty of functions that really speed things up.

Next for me was setting up MailCatcher

MailCatcher runs a super simple SMTP server which catches any message sent to it to display in a web interface

You need mailcatcher if you’re testing sending email out from the site. Here’s what I used:
\curl -sSL https://get.rvm.io | bash
source /etc/profile.d/rvm.sh
rvm install 2.2.2
rvm default@mailcatcher --create do gem install mailcatcher
rvm wrapper default@mailcatcher --no-prefix mailcatcher catchmail

You also need to add the following in /etc/php5/apache2/php.ini:

sendmail_path =  /usr/local/rvm/wrappers/default/catchmail -f some@from.address #

(and restart apache after that)

Next you need to install the codeception mailcatcher module using composer

"captbaritone/mailcatcher-codeception-module": "1.*"

And set the configuration inacceptance.suite.yml

You might get by with only that, but I had trouble with mail being routed through special plugins we use at work, so I had to install the ‘mailcatcher’ plugin

After that it was smooth testing …

Codeception Testing – Part 1

I started working on automating testing ( BDD style ) a few weeks ago, and it took me a while to go over the available tools and options. The obvious starting point was cucumber. Which then led me to Behat, which then took me to Codeception.

When someone tells you it works out of the box, you should always take that with a pinch of salt. Of course, if you follow the quickstart page, it will take you through the different steps that you would take to unwrap the shrink around the box, open it up, take the protective foam bar out, … You get my drift.

Turns out you would need a few more ingredients before you could start testing. Here’s what I needed:

  1. Download and run selenium
  2. Download and install chromedriver
  3. Setup PhpStorm with Codeception

Of course if you’re using the PhpBrowser for testing (no Javascript with that sorry),  you could get started faster. So no nagging please.

And, if you’re like me, going to test WordPress sites themes and plugins, you might find the WPBrowser very useful.

Here’s a list of the steps I took locally on an Ubuntu 15.10 machine (that already had Google Chrome installed)

If you didn’t have Chrome (or installing on a server):

wget https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
dpkg -i google-chrome-stable_current_amd64.deb
apt-get install -f # dirty shortcut to get apt to install dependencies for you!

wget http://goo.gl/rQhaxb -O /opt/selenium-server-standalone.jar
sudo apt-get install xvfb
alias run_selenium="DISPLAY=:1 xvfb-run java -jar /opt/selenium-server-standalone.jar"

wget -N http://chromedriver.storage.googleapis.com/2.20/chromedriver_linux64.zip
unzip chromedriver_linux64.zip
chmod +x chromedriver

sudo mv -f chromedriver /usr/local/share/chromedriver
sudo ln -s /usr/local/share/chromedriver /usr/local/bin/chromedriver
sudo ln -s /usr/local/share/chromedriver /usr/bin/chromedriver

A couple of parting notes:

  1. WebDriver and PhpBrowser do not work together, one of them must be commented out when you’re testing. Pretty obvious when you think about it!
  2. When  you change browser to ‘chrome’, you should also add ‘http_proxy: direct’ in the acceptance.suite.yml

Email Tracking

Most email clients can request a return receipt. One way to set this up in Thunderbird for example is to go to “Preferences > Advanced > General > Return Receipts …” and check the “When sending messages, always request a return receipt”

The problem with this approach is that when the person you’re emailing has set his email client to reject that request (or does that manually every time), you will not get a receipt back. And honestly speaking there is no way to force that. Now there are some services out there that promise to track your mail when that’s read, and those rely on embedding a transparent gif that will call home when the message is opened. I tried a few of these services: the free ones did not deliver (or seemed too shady for my taste) and the paid ones did not look too good either. So I cooked up a quick solution that I can use when needed (like when I’m tracking my brother on his honeymoon trip *evil grin*)

The code is below, pretty self explanatory. You will need a transparent gif/png. That’s easy too 😉

Edit: Looks like some services are not so bad. Checkout bananatag and YesWare Email Tracking
