Project: Migrate from YUI2 to YUI3. Bug 453268
Assigned Mentor: Mr Byron Jones
Git Fork: https://github.com/ishitvagoel/bugzilla
Short description: The present stable release of Bugzilla uses YUI2 library for its user interface which is now deprecated and is no longer maintained . There is a compelling need to migrate to the latest version of YUI that is YUI3 as it is a more secure and an actively maintained framework . Therefore in this application , I propose to perform the task of complete migration of the Bugzilla codebase from YUI2 to YUI3 and subsequently carry on the task of refactoring the code.
Weekly Updates
Community Bonding Period:
The community bonding period was used for the experimentation purpose, the summary of the work done is as follows :
- Discussed with my mentor the approach to be used for loading the YUI modules. We tried various approaches like using a separate JS file for creating a YUI instance with the required modules loaded and then including this file on all the Template files which used the YUI code or the code in the JS files. This approach didn't seem viable as then we would have had to load all the modules attached to the YUI instance on all the template pages. So we then finally decided to create a yui3 array on global/header.html.tmpl file, with “node” as the default module to be loaded and then subsequently use the push method to add modules to this array on the template pages to load the required modules during the runtime.To implement this we came up with the following changes to the codebase, as suggested by my mentor, global/header.html.tmpl changes. These changes are yet to be tested.
- We tried to migrate the js/TUI.js file and came up with these changes: TUI.js changes A special thanks to Mr Clarence Leung (Yahoo) who provided valuable feedback during this work.
- Learnt about using the Debugger Tool of Firefox : Debugger . As my mentor has suggested, we will be using this tool to test the changes which we will be making to the codebase. We will be using breakpoints to check whether the functions defined inside the JS files are getting hit or not and also to test for any other errors.
Week 1, 19th May-26th May 2014
- Committed the changes to the js/attachment.js file to the git fork: js/attachment.js changes. The changes to this file also are yet to be tested.
NOTE: I will be having my final exams at college for which I will have to prepare full time, so I have taken permission from my mentor to take a preparatory break till 5th June 2014. After that all the pending work will be taken care off. All the remaining testing work will be done and after that only further migrations will be performed.
