The new GSoC students will certainly benefit from your words of wisdom on how to have a successful project ;) I've not given the COMDEV-109 project a lot thought, so others might have better feedback. It seems to me that you'll might want to consider where to store everything in the environment directory, including the SQLite db file for the case of running SQLite (although perhaps the project could be limited to PostgreSQL and MySQL installations). Focusing on file attachment storage might be a good way to limit the scope though. I assume you'll need to add an API to Trac for integrating with external services, as well as integrating with at least one service. Studying and considering several services might help with determining how to make a suitable API, which appears to be what you are already doing. I imagine there will be some significant changes to the Trac code, which we can then push upstream to the Trac project (you can leave that part to us for the sake of keeping your project of reasonable scope, and we'll make sure you are credited as the author of the changes submitted to Trac). I've seen discussions mentions of using Trac on Heroku and Google App engine, but I'm not sure anyone has deployed it to those targets: http://trac.edgewall.org/ticket/11339 http://trac.edgewall.org/ticket/10433 To answer your specific questions, Where can I find the modules that deal with file uploading/storing at the > moment? You'll want to look at the trac/attachment.py module. If you consider the configuration data to be in the scope of your project, then you may also want to look at trac/config.py. Is there any existing integration between Bloodhound and Google App Engine, > as it would make Google Drive integration easier? None that I know of. It wouldn't hurt to ask on trac-users or trac-dev mailing lists as well, after scouring StackOverflow and similar forums to see if anyone has done something similar. http://trac.edgewall.org/wiki/MailingList It seems to me that this is a very useful project, which could significantly lower the barrier to deploying Bloodhound. A large percentage of the activity on the Bloodhound and Trac users mailing lists is due to users having trouble with installation steps, including web server configuration. If we could deploy to Google App engine in a minimal number of steps, we might capture a much larger user base - those that might not otherwise be willing to fight through the installation steps - as well as saving ourselves time supporting users with installation issues. Bitnami Trac has lowered the barrier for Windows users, but I haven't seen an equivalent for Linux. I'm not sure it is in the scope of your project, but creating a simple deployment to, for instance Google App engine, would be a great project. There was another student that expressed interest in the COMDEV-109 project after you, so maybe we can have multiple projects that converge to that end goal. - Ryan
