On Tuesday, I managed to land a fix for another Launchpad bug. This one probably was my first non-trivial bug fix and also older than any other bug I’ve attempted (4-digit bug!)
Earlier, during page load, Launchpad would take each bug, search if its, valid, get the title, and show tooltips. This feature was removed to reduce page load times and timeouts. Instead, anything that matches the bug pattern gets linked whether the bug is valid or not. Obviously, less friendly, but much faster. One of the days, there was a general complaint about this in #launchpad-dev and Ian Booth mentioned that its probably trivial to fix with the link checking bits he wrote for branches. I jumped in when I saw a chance to get mentored for a bug.
