git-svn under Ubuntu 11.10

Right after upgrading to Ubuntu 11.10 I faced with a git-svn issue:

Byte order is not compatible at ../../lib/Storable.pm (autosplit into ../../lib/auto/Storable/_retrieve.al) line 380, at /usr/share/perl/5.12/Memoize/Storable.pm line 21

Could not unmemoize function `lookup_svn_merge', because it was not memoized to begin with at /usr/lib/git-core/git-svn line 3213
END failed--call queue aborted at /usr/lib/git-core/git-svn line 40.

The solution is so simple

Add the line

$Storable::interwork_56_64bit = 1;

near the top of /usr/lib/git-core/git-svn, just after the version definition.

New version of Definitive guide to symfony

The old-new basic documentation of the framework is coming. It has a new title: Gentle introduction. A little bit raw in its current format, but fantastic. I’ve used it to write functional test for a symfony 1.4 app. Well written, offered reading.

My colleague wrote an excellent article about code quality measurement tools in PHP. I would like to emphasize it’s about the tools not the techniques. At the end of the post he also provides a great summary of authors (twitter, blog, book) of the related topics.

CouchDB logger for symfony

I’ve created a new logger for symfony with CouchDB backend. Feel free to drop it to your lib/ dir and use it: http://gist.github.com/313539.

logger:
  class: sfAggregateLogger
  param:
    level: debug
    loggers:
      # ...
      couchdb_debug:
        class: CouchDBLogger
        param:
          level: debug
          url: http://localhost:5984 # defualt value
          dbname: logs
          type: test_project  

You have to create a database before use it. This implementation uses PHP’s HTTP stream wrapper, so you have to enable allow_url_fopen ini directive.

Create an autoloader with closure in php 5.3

During the development of my framework essence I found closures very usefull to create an autoloader.

This is a simplified version of the code, I use in greebo:

static function register($base_dir)
{
  $base_dir = rtrim($base_dir, '/').'/';

  spl_autoload_register(function($class) use($base_dir) {
    $class = str_replace('\\', '/', $class.'.php');
    $file = $base_dir.ltrim($class, '/');
    if (file_exists($file)) {
      require $file;
    }
  });
}

If you have a valuable idea Drink tea. If the idea remains after the tea Perhaps it has some value. However, If you drink tea, but the idea remained, Perhaps you simply have not learned how to drink tea.

Using null object pattern with Doctrine

A lot of resource out there about null object pattern. Fundamentally this is a design pattern that describes an object what behave like a null value, but it can be handled as a regular object in the given context.

Let’s see the benefit of this pattern with Doctrine.
