Publ v0.5.6 released

Oops, I’d been sitting on a bunch of bugfixes for a month, which I didn’t notice until I put in another bugfix tonight.

Changes since v0.5.5:

• Fix title sanitization
• Handle category.name with the same formatting options as entry.title
• Replace hand-rolled atomic file operations with atomicwrites
• Add link_class to image renditions
• Fix automatic alt generation for external images
• Simplify the way entry URLs are canonicized
• Fix some bitrot in older tests

Why Publ won’t support magic auth links

Since adding user authentication to Publ, I’ve been thinking of ways of allowing people to subscribe to sites from feed readers while getting their own native authorization, so that people can see entries directly in their readers rather than needing the clumsy mechanisms of unauthorized placeholder entries.

Out of the box, Publ authentication does support a shared cookie jar; if you can provide your cookies to your feed reader in some way, then things will Just Work. Unfortunately, I don’t know of any feed readers that actually support this, at least not easily. (Back when most browsers had a feed reader built-in this was a lot simpler. But time marches on.)

The two mechanisms which seemed most promising are AutoAuth and “magic links,” where users get signed URLs that come pre-authenticated and show the full authorized content for that user. AutoAuth is still in a draft phase that’s stuck in a chicken-and-egg situation (and also requires a lot of buy-in to IndieWeb protocols, which is still a pill too large to swallow for most of the folks who follow my blog), so magic feed links seemed like the best path forward.

I even got so far as to draft out an implementation, but there’s a few bad issues with it which just made me opt not to.
