Time Spent

11 hours.

Highlights

Storm is by far the most intuitive way I have ever dealt with relational databases. Because of its pretty integration with Zope in Launchpad, I was able to make modifications to the core in a brief, consistent and non-disruptive way.

Concerns

While searching each attachment on the remote server works uber-fast, I don’t think it’ll be easy to have such a feature merged upstream. It may be argued that going through each file at the server side produces unnecessary load. In order to address such concerns I’ll have to generate relevant statistics after testing the changes extensively.

I still don’t understand Launchpad’s branch structure in detail. I’ve noticed that my branches are forked from devel-db instead of devel. I’m confused about the implications this will have on merge proposals and will consult Bryce about it tonight.

Waiting Items

None.

Stalled Items

None.

Minor Tasks

To simplify the task of debugging Launchpad, I gave my Ubuntu VM remote-access and edited Apache configuration accordingly. Now I can just make changes to the sources using NFS mounted branches and test them in my host browser using launchpad.dev.

Actions for the Following Report

I haven’t yet decided whether I should focus on getting these changes merged into trunk yet or instead move on to launchpadlib and arsenal aspect of my project. Guess I’ll just add the matter to the list of items I need to discuss during tonight’s IRC meeting.
