Help! I Can't Set A Catalog Product Collection's Page Size

Published: January 18, 2017

I ran up against a pretty interesting issue recently. I was looking to render a custom block (descendant of Mage_Catalog_Block_Product_List) in a CMS block. You can do this with template variables…

{{block type="mpchadwick_customproductlist/list" template="mpchadwick/customproductlist/list.phtml"}}

Then, in my custom product list block I was setting up the collection in the constructor.

<?php

class Mpchadwick_CustomProductList_Block_List extends Mage_Catalog_Block_Product_List
{

    protected $helper;

    protected function _construct()
    {
    
        $this->helper = Mage::helper('mpchadwick_customproductlist');
        
        $collection = Mage::getModel('catalog/product')
            ->getCollection();
        
        $helper->filterCollection($collection);       
        
        $this->setCollection($collection);
         
        return parent::_construct();
    }
}

One of the things I was looking to do in the filterCollection was set the page size. However, no matter what I did (e.g. setPageSize, setPage, limit on the Varien_Db_Select object) it still wouldn’t work.

Finally, after an hour of pulling out my hair, I figured out why.

aspell really doesn’t like curly quotes…

$ echo "This really shouldn’t fail" | aspell list
shouldn

$ echo "This really shouldn't fail" | aspell list

I ran up against this issue looking into adding a spell check featured for jekyll-pre-commit.

As a developer, there’s a good chance you spend more time reading code than you do writing it. In the world of Magento, a lot of that time will be spent reading through the source code of custom and community modules.

In this post, I’ll provide some tips to help you understand how these modules work.

Why Local Profiling Alone Is Insufficient For Performance Optimization

Published: January 3, 2017

When your goal is to make a web site load faster, the first logical step is to hook your local development environment up to a tool like XHProf, or Blackfire. This is definitely a good thing to do to get some sense of how the code is executing and where the bottlenecks are. However, if this is the only thing you do to review performance, there’s a good chance you’re going to miss something. Let me tell you what else is needed and why.

Titles like “Critical PHPMailer Flaw leaves Millions of Websites Vulnerable to Remote Exploit” or “PHPMailer Bug Leaves Millions of Websites Open to Attack” are great if you’re looking for clicks. However, when you take a closer look, you’ll see that these aren’t exactly accurate.

Here, I’ll take a level-headed look at recent vulnerabilities found in PHPMailer, CVE-2016-10033 and CVE-2016-10045.

Between massive log files and big code bases, if you’re a developer, there’s a good chance you spend a lot of time searching.

grep is typically the old standby here. I know I’ve used it just about every day for as long as I can remember.

However, there’s a new kid on the block that goes by the name of ripgrep (executable as rg) that’s really stirring things up. Let me show you what there is to like about ripgrep.
