In spirit of last night’s COSI meeting, I figured I should get ahead of the game and post a little bit about what I’ve been up to with OSP. There were a number of shortcomings with the 0.2 release in terms of permanent storage and replication. Since r65 (version 0.2) there have been a number of changes, mostly some old ones centered on ERLFS and the most recent ones, which tweak the mnesia settings. Below are some important revisions and their impact:

• r88 – Now will autosense is a node has a disk, and will determine whether or not to keep a copy of the applications table on the disk or just in RAM
• r89 – Made gen-join.pl which asks the user a bunch of questions to make a join script for easier setup
• r93 – When you first install OSP, you should run ./setup-osp.sh to initialize the database on the first/master node
• r96 – Added the add-backup-server, which will make a disk copy of all the tables to that backup server incase of node failure, there’s a backup copy

While thse changes are small, they are still very needed in creating an actual application. Currently, OSP is at r97, only 3 away from the big 100. I thought that we should have a mini OSP party when we reach r100, but since OSP is distributed, so should the party. So when you get word of the 100th commit, please raise a glass or eat a slice of cake.
