Let the Testing Commence

After a fair bit of work (feels like longer than 2 months) I’ve finally managed to get bug 382752 landed. What this gives us in simple terms is a set of functions that we can use in order to do unit testing on the extension manager. Alongside I have checked in the first unit test. Now if anything regresses bug 257155 we should know about it immediately.

Ignoring the regression detection, I’ve always found unit tests to be fantastically useful when developing new code or fixing bugs. Zipwriter is a prime example, with a large number of tests that I can run by typing a single command I can test whether the changes I have made have solved the problem and not introduced any other errors.

The next step of course is to start adding unit tests for the extension manager. I have some already in progress and hopefully soon some of the key parts of the EM should be getting checked on a daily basis.

Securing Add-on Updates

Since the disclosure of potential vulnerabilities in the way Firefox (and other Mozilla applications) automatically update your add-ons we have been discussing how to tighten up the system in a way that is hopefully unnoticeable to users and not much extra work for add-on authors.

After a process of listening to authors on the newsgroups, forums and by email we now have a rough proposal of what changes we are looking to make. There’s still a few minor details to be ironed out of course. This is mainly of interest to add-on authors since there is an impact depending on how you host your updates. I’ve started threads on the newsgroup and forums so if you want to discuss the proposal there then that’d be good. I’d prefer it if you didn’t edit the main page of the wiki but feel free to stick small comments onto the discussion page.
