Composer workflow for developing proprietary Magento 2 extensions

5 Replies

PHP Composer LogoIt appears future came for us Magento developers in the end. Magento 2 platform is alive and kicking, and with it modern PHP tools like Composer entered our daily routine. And it's so much easier now the Composer is here to take care of my dependencies! Khm. Not so fast. To be honest, packaging software into neat fully decoupled packages is still a utopia. We model tightly coupled reality which is not something you can hide behind package manager.

Blank product page with Magento compilation enabled

1 Reply

Magento Standard Router BugBefore we seriously step into Magento 2 era, please allow me to dissect one more Magento 1 bug. Couple of weeks ago we enabled compilation at one of our client's Magento EE installation as a part of holiday traffic preparations. Goal was to take advantage of performance boost provided by avoiding Magento autoloader through compiling all the Magento classes into several bulky PHP files.

I like to believe this is a good thing, because besides helping other Magento developers, finding and fixing bugs makes our favorite ecommerce platform better. It has nothing to do with frustration couple of days debugging session can cause, I ensure you. In this article I'm about to explain and provide workaround for bug affecting all Magento versions (including latest Magento CE 1.9.0.1 at the time of writing), one that's causing catalog price rules not being applied to final price and totals not getting calculated correctly when creating orders from Magento admin, all this under specific and hard to reproduce circumstances. Honestly, this is probably the ugliest bug I've ever seen in my coding career, largely due to fact that client's bug report is usually that catalog price rules prices revert when creating orders from Magento admin, but only sometimes and without any pattern.
