Release Cleanup: Day 7

I slowed down a fair bit on Odysseus development over the previous 3 days because I was busy graduating in Computer Science. However I did manage get some work done over those days and I finished that chunk of work today.

It’s kind’ve appropriate that I graduated whilst cleaning up this chunk, Odysseus’s templating language “Prosody”, as that component best shows off my competancy at Computer Science. But I also took some of that time to configure Odysseus’s branding, much of which can be seen on my website, as well as to fix some very serious problems that showed up (and hid) during my previous refactoring.

These issues included:

Opening external URLs started to crash Odysseus
The immediate fix to this was to ensure that the trait which handed URLs off to the system would register event handlers before the error handling code opened a page which was at that moment causing the crash.
Later I fixed that page by switching the broken { % trans % } tag with the { % with % } implementation, but tomorrow I'll have to do something better.
First start appeared to do nothing
The check I used wasn't working, so instead I have first launch triggered by updating the database from version 0.
I've been struggling to delete rows from the database
I've been aware of this problem for a while, and because SQLite's making some complaint foreign keys I simply removed them.
This change is not backwards compatible.

But mostly I focused on numerous small fixes to my “Prosody” templating language, of which highlights include:

It does make me a bit uneasy to have implemented my own string escaping logic, because I know that if a miss any bit of subtlety will not only allow Odysseus to visually mess up but also for websites to mount an XSS attack via the local SQLite database which tracks their history (and will do so more). So while I’ve reread this several times, please check the code out for yourself to see if I’ve missed anything.

Next on my list is to finish up with a brand new i18n infrastructure which does not crash, tests for importing and using template “blocks”, and enabling those tags. After that I think I have enough time to add a few simple and very elementary features to Odysseus.
