As a lead developer at Mutable Labs I was tasked to find a way to do recursive deletion in Yii. As I asked other developers and looked around the internet the usual answers all came up, use a plugin or use cascade delete at the DB level, but I did not want to do either of these.
A big problem I've hit with the Yii-Bootstrap extension is that all AJAX requests are initializing Bootstrap because of preload. This is a huge waste of resources, especially when using AJAX-based file uploaders that split the file into chunks. Large file uploads using that method could be initializing bootstrap hundreds of times.
