Back in they day, I ran a Tumblr blog named Magento Quickies where I’d post shorter, less in-depth posts about my travels through Magento’s source code. This Programming Quickies categories is the successor to that Tumblr blog. You’ll find all the old Magento Quickies content here, as well as new short posts about programming in general.
This section has its own RSS feed, the old Magento Quickies feed should should be redirecting, and we’re cross posting notifications for new posts over to magento-quickies.tumblr.com. In other words, you shouldn’t need to know any of this, but the duct tape that keeps the internet held together isn’t aging well, so your mileage may vary.
Below you'll find all the Programming Quickies articles on the site, followed by a chronological listing of the same. You may also browse the 7 series directly via the following links. Pestle, Four Steps to Async Iterators, Checking in on OpenMage and Magento in 2020, Text Encoding and Unicode, Shopware's Development Environment, A Sentimental Gen-X Programmer Culls his Tech Books, and, Containers, Containers, Containers.
Permission issues with static generated files in pub directory · Issue #2412 · magento/magento2 I built my first website in 1995 – which means I’ve had over 20 years of battling unix file permissions.

astormThese methods aren’t, as of 2.01, marked as @api safe so they may go away. That said, they’re pretty integral to how the layout works so I feel like they have a good shot of sticking around.

astormNot strictly a Magento 2 thing, but if you have code that looks like this in your extension namespace FooBazBar; //... if( $node instanceof SimpleXMLElement) {} You’ll need to make sure that SimpleXMLElement is actually used in your current namespace. namespace FooBazBar; use SimpleXMLElement //... if( $node instanceof [...]

astormBased on some early theme conversion work in Magento 2 – it looks like the view.xml theme fallback is an all or other thing. If your new theme’s view.xml file is missing an image that’s defined in the parent theme file, Magento explodes when trying to find the parent image file.
astormCan’t Create URLs Shorter than Three Characters · Issue #2910 · magento/magento2 Reminder: In Magento 2 (as in Magento 1) a route’s name is how Magento internally identifies the route, and uses it for creating things like layout handles. The front name is what shows up in the URL bar. These are very often the same, but [...]
astormCan’t Create URLs with Single Dashes · Issue #2910 · magento/magento2 One of the downsides of creating a new framework is you end up creating the same problems that have already been solved in other frameworks. For some reason Magento 2 wants all URL “front names” (the first URL segment) to be three characters long, and [...]
