We started our RubyGems Hackfest Saturday, with a turnout of 6
people. Five were regulars from Seattle.rb, and we even got someone
up from Portland! We started Saturday by brainstorming things we'd
like, writing up story cards, estimating and risking them. Then we
paired up and got testing!
By the end of day 1, we'd finished cards 1-3 and gotten pretty good
testing infrastructure in place for stuff we needed. I spent some
extra time making it so that all unit tests generate their gems on
the fly, weren't dependent on the location from which they were run,
and didn't use or create any files in the test directory. We went
over our estimates by 3.5 hours. Much of that was my fault, it was
too hot for me to think.
On day 2, we were down to 4 people, but had much better testing
capabilities. Aaron and Evan finished up the package listing command
extension and gave .gemrc the ability to have .cvsrc-style command
option specifications. Eric and I worked on the hardest bug we had,
which was to get rid of the use of Date. We succeeded on both counts!
We went over by 1 hour on a task, and under by 1 hour on the other.
YAY! I've been wanting to conquer this issue for quite some time!
