More more static rendering....

Note: This is an old post in a blog with a lot of posts. The world has changed, technologies have changed, and I've changed. It's likely this is out of date and not representative. Let me know if you think this is something that needs updating.

I checked in some fixes to the static rendering code and it's working nicely. I fixed my flavour files, made some adjustments to my plugins and then re-rendered everything. My statically rendered site is at /~willkg/test/.

Things the static renderer is not good at:

  • figuring out if an entry has moved from one category to another (you'll probably end up with two versions)

  • comments (if someone adds a comment, that doesn't adjust the mtime on the entry file, so we won't re-render)

  • figuring out if material has changed on other pages (if you add an entry to april on the 4th, the other april pages won't reflect this in the calendar--they would need to be re-rendered but pyblosxom can't figure that out nicely in a general fashion)

Those are somewhat complex problems. One way to fix them is to store a record of which pages belong to which categories and dates. So then if an entry is updated in April, we'd figure out that we really need to update all April entries. That fixes the immediate problem of pycalendar, but doesn't provide a generic fix and I'd prefer not to have to store records of things if I don't have to.

Robert suggested I add a callback for plugins to tell me what urls need to be rendered. If you extrapolate on that, the plugins could also take a look at what's changed since the last time we rendered and figure out the related pages that also need to be re-rendered. For example, pycalendar could implement the callback, get a list of entries that are going to be re-rendered, notice that one of them is in april, and then tell Pyblosxom all the April entries need to be re-rendered as well as the entries in May (because of the "next month" link) and March (because of the "previous month" link). Not sure that's a really wildly good idea. And the effort involved is pretty high. I think it'd be easier on everyone if the suggested fix is to build a cron script that does this:

cd /home/willkg/public_html/cgi-bin/
./pyblosxom.cgi --static
find /home/willkg/public_html/test -mmin +30 -exec 'rm' '{}' ';'

That'll run the static renderer and then remove any file that was modified over 30 minutes ago (i.e. it didn't get touched by the static renderer).
