Jenkins fails Maven/Java builds when running API tests using HTTPS

Recently discovered the problem with Jenkins, when projects builds were failing due to REST API tests (RestAssured) fails for an unknown reason.

We've recently switched our infrastructure to HTTPS and that change was obviously the root cause as the tests on HTTP were passing successfully.

On local developer's machines, the QA servers or even on Jenkins machine tests were passing when running from bash.

Also tried to run them from the "jenkins" user, on Jenkins machine, from the build's workspace -
in the exact same way Jenkins runs during a build, and all tests were passing successfully on both HTTP and HTTPS.

HTTPS tests were failing only when started from Jenkins UI "Build Now" button. We were not able to reproduce these fails any other environment except this Jenkins instance.

Cheap ExtJS 4.x SASS watcher (ready to be wrapped with gulp/grund or any other build tool)

ExtJS 4.x does't has reliable SASS watcher out of the box. Recommended approach of "compass watch" introduced in ExtJS 4.x doesn't works anymore in ExtJS 4.2 as it doesn't understand the structure of themes, leaving "sencha ant sass" as only option to build SASS, which is so slooooow and takes around 30-40 seconds to rebuild the whole theme.

URL params parsing on pure JavaScript

ES3 compatible URL params parsing on pure JavaScript:

* Detects hash params and builds an array of values
* We have the following URL: ""
* this function will extract the part: "param1=value1&param2=value2" and build an array:
* param1 = value1
* param2 = value2
* inspired by:
* @returns {Array}
function getHashVars()  {
    var vars = [], hash;
    var hashes = window.location.href.slice(window.location.href.indexOf('#') + 1).split('&');
    for(var i = 0; i < hashes.length; i++) {
        hash = hashes[i].split('=');
        vars[hash[0]] = hash[1];
    return vars;

Convert OpenSSH keys to Putty on Linux with puttygen

If you need a Putty ppk key on Linux when you don't have Windows installation, for example when using Windows application that requires ppk-key under Wine. You can use "puttygen" CLI tool in that case.

On Ubuntu:

# apt-get install putty-tools

$ cd ~/.ssh/
$ puttygen id_dsa -o id_dsa.ppk

Make sure you've replaced the "id_dsa" with your private key filename.

Look at this presentation to become familiar with PHP profiling:
And also look into this article for more details:

Edit PHP.ini and add the line:
xdebug.profiler_enable = 1
Restart the Apache and you will find the profiling dumps in /tmp/ .

PHP debug process internals with xdebug

Xdebug debugger allows you to interactively walk through script execution and inspect the call traces and variable values in each appropriate scope.

Why install xdebug?

Even without actual integration with your IDE you are able to get benefit from xdebug on your development machine:

PHP debug & profiling for dummies

Sometimes very basic debug can be done by dumping the values of variables. The other method is about writing debug values into log files. Such approaches are hard to be successfully used on large sophisticated projects like Drupal or Magento. In such case the best solution is to use the debugger and debug your code via step by step code execution, back traces, breakpoints, variables scope inspection and producing execution flows / profiling dumps.

Here is the short compilation of materials about debug and profiling in PHP where everyone can find links to the interesting materials on the WEB and also my personal experience.

Zend Mail 2.0 to be delivered for upcoming ZF2 beta2

The work under new Zend Mail 2.0 component has been started recently. Matthew Weier O'Phinney created the architectural outline of proposed object relations and interactions. That document can be found under following Wiki page: "RFC - Mail Refactoring"

Mail goals that should be addressed in new Zend Mail component are:
  • handing of mass messaging
  • better separation between message handing and transport
  • improved MIME-types encoding and Unicode support
  • more intuitive handing of attachments and custom message headers
Feel free to provide your comments under the appropriate Wiki page according the proposed architecture.

Revised version of Zend Mail 2.0 is planed to be delivered for upcoming Zend Framework 2 beta2 release.

Simplest solution to enable PHP mail() function under Ubuntu

If PHP mail() function doesn't works on your development desktop and your Apache error log shows something like "sh: /usr/sbin/sendmail: not found" - then you obviously need to install "sendmail" in order to fix that :)

Just run the following command in Ubuntu:

# apt-get install sendmail

To configure Sendmail for your needs use (see appropriate configuration scripts in output):

# sendmailconfig 

Writing this post for people who asking me quite frequently: "Why PHP mail() function doesn't works after I've successfully installed LAMP development environment on my Ubuntu desktop?"
