Midway Update – Wei Xian Woo (Thunderbird)
Posted by wxwoo on 2010/02/28
I am not proud to say this, but my performance on Thunderbird could have been better.
Am I behind?
- Yes, I am at least three weeks behind the schedule I set for myself. I would have liked to submit my first patch by the end of January, but I ended up doing that only in the third week of February.
- At the start of the term, I broke down the feature I was responsible for implementing into reasonably sized pieces and estimated that each piece will take approximately 1-2 days to implement. Even at this point, I feel that those estimations were fair and achievable given what I knew about my schedule at the time.
Why am I behind?
- The term turned out to be a lot busier than I originally anticipated – for school (assignments + a research assistantship) and preparation for external exams
- Figuring out how certain pieces of Thunderbird code interact with each other and where certain things are took longer than expected. For example, where/when is the first Thunderbird main window created? (No, searching for “startup” and other related keywords did not help.)
- I spent almost two full weeks understanding the various types of Mozilla unit tests and identifying one that can do what I need. Mozilla has 7-8 types of these, out of which only 3-4 of them are currently used in Thunderbird. This time I felt was badly spent because asking Blake (which I had to do anyways) would have gotten me an answer much quicker.
What have I learnt up to this point?
- Writing tests – despite having five co-op work terms of development experience, I definitely learnt some good stuff about testing here.
So, how’s the remainder of the term going to look like for me?
- Within the next 2-3 weeks, I hope to finish up the remaining pieces of the feature. In fact, my revised 1st patch is almost ready as I write this and should be ready for submission sometime today.
- I hope to be able to work on at least one other bug for the final month, which will hopefully take less time to tackle now that I have better understanding of how things work in Thunderbird.
