v0.2.1 released

Just a couple of minor fixes in this release:

• Fixed a nasty bug with date header rewriting
• Also disabled the math-explicit extension on Misaka, because it did pretty much the opposite of what the name implied

Update to v0.2.0

A few changes since v0.1.24:

• Updated code to use the current Flask cache-control API
• Only set cache-control for responses that don’t have a natural cache response
• Entry IDs and UUIDs are now semi-stably generated, in order to prevent (or at least reduce) problems like the last time

Publ itself is stable enough (and enough has changed since v0.1.0) that I felt that a minor version bump was a reasonable thing to do.

Anyway! While Publ has been running quite nicely on my website, I’d love to see more people actively using and developing it. This site in particular needs a lot of attention and probably reworking; my other top priorities are:

• A better installation/deployment guide
• Proper test coverage (rather than manual smoke tests)

The downside to running on Heroku

So, sorry to anyone who was subscribed to the RSS feed for this and got spammed with v0.1.24 release announcements. I made a mistake and pushed a version of the entry that didn’t have a canonical ID assigned yet, and as a result, every time Heroku spun up, it assigned a new ID. This is something that’s happened before and I really ought to do something about it.

Three things come to mind:

1. Figuring out how to always make IDs get assigned in an idempotent manner (hard to do correctly)
2. Don’t run on Heroku so the assignments persist between executions (easy)
3. Add a pre-push hook to the repo that verifies that all entries alread have an assigned ID (???)

2 seems like the easiest approach for now, so that’s what I’ll probably do.

Verson 0.1.24 released

New functionality:

• The image rendition cache now gets periodically purged; the default is to delete renditions which haven’t been used in the last week (this can be disabled)

Bug fixes:

• entry.title can now accept the no_smartquotes parameter, which is necessary in Atom feeds
• entry.card now uses the same Markdown extensions as entry.body

v0.1.23 updates, oh yeah this is beta now

I neglected to mention that I set Publ to beta status in v0.1.22, which was a minor bugfix release, rather than moving to 0.2 like I previously stated. The changes for 0.1.22 were:

• Fixes to category Sort-Name
• Added support for regex path-alias hooks (this is configured on the Python/WSGI side, and has been working quite nicely over on beesbuzz.biz)
• Fixed a dumb bug in the cache-control headers

And then the changes for 0.1.23:

• Enable automatic smart-quote substitutions (this is the default setting, and can be overridden by passing no_smartquotes=True to entry.body/entry.more/entry.title)
• Improve the handling of last-modified times on entries (now there’s a Last-Modified header which only gets set when you want it to be)

My site templates

I released some of my site templates; hopefully this will be helpful to others.

v0.1.21 - final(?) alpha release

This server is now running Publ v0.1.21, which I believe will be the final beta version; all of the release blockers have been taken care of. And as a bonus I also implemented the ability to include template fragments, which allows templates' content to change formatting based on the category of the formatted entries. This is particularly useful on Atom feeds, where you might want to have different entry formats for each category. I’m already using it on busybee, to provide full-content feeds in ways that make sense for the different site sections.

I will play with this for a few days and if I’m happy with it I’ll be releasing v0.2.0, which will be the first beta release. In the meantime I’ll also look into packaging up busybee’s templates for other people to use as a starting point, because I know that setting up a new site right now can be incredibly overwhelming!

v0.1.19: creeping ever closer to beta status

The amount of stuff I’m having to fix in Publ to support beesbuzz.biz is diminishing rapidly! Here’s what’s happened since 0.1.18:

• Improved the Path-Alias redirection logic; now it will do a 301 Permanently Moved for inbound Path-Aliased requests, and if a Path-Alias points to an entry with a Redirect-To it will redirect directly to that URL instead (and it will be a 302, same as the old Redirect-To behavior)
• Pagination can now be weekly; you can use entry.archive(paging='week'), and a ?date= view parameter ending in _w will provide a weekly view instead.
• Better default formatting for view.range, and an addition of a week format parameter there

In better news, v0.1.18

So aside from the Dreamhost issues, I would like to share what’s new in the latest version as part of my big “get my website online” push:

• PERFORMANCE: Improved the threading mechanisms around image renditions for better stability and performance
• BUGFIX: Made markup tagging work consistently between image types
• FEATURE: view.link() now allows overriding category
• FEATURE: You can now mark an entry with an Entry-Status of DELETED or GONE, which results in a 410 error instead of a 404 (be the envy of your web-developer nerd friends!)
• FEATURE: Error templates will automatically use the x00 error code as a potential fallback (e.g. error code 503 will also fall back to a template for 500)
• FEATURE: Entry titles can now have Markdown in them, and it usually works most of the time!
• BUGFIX: Now when running in debug mode you don’t end up with two watchdog threads
• FEATURE/QUALITY: Refactored the way error pages are handled, and now if you get a 404-type error on a page while the index is being asynchronously scanned, it’ll turn into a 503 with a Retry-After disposition in case it’s just something that hasn’t been indexed yet
• UX: View pagination URLs now all use id as the query parameter rather than a miasma of contextually-dependent start, last, or first which made no sense anyway

So much for Dreamhost

One of the overarching reasons I decided to build Publ the way I did was in order to take advantage of Dreamhost’s support for Passenger WSGI. I was expecting that to be the primary means of hosting my main site (which is way too big for a Heroku instance) and given how smoothly things were working with this site on Dreamhost I figured it wouldn’t be a big deal.

However, there was a huge monkey wrench thrown into things when I switched my site’s configuration over to Passenger; despite all of my configuration being exactly the same between publ.beesbuzz.biz and beesbuzz.biz, the rendition cache on beesbuzz.biz was getting its permissions set wrong, and there was some rather weird behavior with how it was making the temporary files to begin with.

In investigating this I attempted to upgrade my packages on publ.beesbuzz.biz, and all h*ck broke loose.

Lots of bug fixes, and more image features (v0.1.17)

Oh, it’s been a little while since I’ve posted an update, hasn’t it? That’s because I’ve been very busy building the templates for my personal site! In doing so I’ve greatly improved the way that view refinements worked, fixed a few silly bugs with image search paths on templates, and also added an easier way to specify background images in CSS, via the image().get_css_background() method.

I’m really excited to be able to bring my first fully-realized Publ site to the public; I hope it gets other people interested in what a flexible publishing system allows them to do!

Template overrides and breadcrumbs

Today I added two new useful features:

• template overrides (including private templates)
• hierarchy breadcrumbs

I also implemented the better date sort mentioned previously.

These things are already making my new personal site look way better and easier to use! I feel like I’m almost ready to flip the switch.

Oh, and I also improved the getting started guide, including adding basic setup instructions for Linux and Windows. Not that I’ve gotten Publ to run on Windows, yet, but documenting how to get the environment set up is the first step, right?

Dates are hard

There’s an old joke in programming, that the two hardest things to do are naming things, cache invalidation, and off-by-one errors. But this doesn’t pay sufficient respect to one of the other hardest things, namely handling date and time.

Asynchronous workers

Today I got two major bits of functionality in: Publ will now asynchronously scan the content index (which speeds up startup and fixes some annoying race conditions with entry creation), and it also asynchronously generates image renditions (which makes pages not take forever to load on first render, and will also use multiple CPU cores if available). Seems to work well so far.

I was running into scaling problems with beesbuzz.biz (what with there being a couple thousand entries and some pages with hundreds of images on it) and this keeps it feeling pretty good.

So, this brings us up to version 0.1.14.

v0.1.13 released

Two major updates for v0.1.13:

• Rewrote the pagination logic to actually work across category-recursive views, and to support pagination where the sort order isn’t necessarily the same between renders
• Refactored images so that the template image() function has access to the tag writer

These changes were made as part of migrating beesbuzz.biz over to Publ, which I’ve made a lot of progress on now. It’s pretty nice getting my overall design proven out, and to shake out all the little bugs and misfeatures.

Hopefully soon I’ll have Publ in a state where I feel comfortable releasing it as beta.

v0.1.12 changes

I just released v0.1.12 which adds a couple of quick, minor-ish fixes to Unicode handling; in particular:

• UTF-8-containing headers no longer get MIME-mangled on first import
• I finally made the automatic slug text way better by switching to awesome-slugify

So, now it’s no longer US-English-centric, at least. Right now it just uses the defaults; at some point I’ll want to make it so that you can configure a site’s or entry’s language locale so that things work better on that end too.

Now with ∞% more OpenGraph support

I have now implemented the basic OpenGraph API to Publ, so now a template can generate an OpenGraph card with entry.card. So in theory when this entry gets autoposted to Twitter, this first paragraph should appear, as should the below image:

Anyway that’s what’s new in v0.1.11 (as well as a bunch of internal refactoring to support this addition).

Even more updates, v0.1.10 released

If you are reading this, it means that Publ v0.1.10 is out. This release is mostly about a few cleanups, such as:

• No longer nests a <div> for an image gallery inside of a containing <p> (which both fixes an HTML validation error and makes styling more controllable)
• Cleans up error handling somewhat
• Also cleans up a bunch of code for property caching

But there’s also a new feature, namely view.range, which you can read about over in the API docs.

I am also making significant progress in porting my main website over to Publ and hopefully I’ll have something to show for it soon. (And I promise it looks way nicer than this site!)

The Trouble with PHP

I’ve had people ask me why I’m not building Publ using PHP. While much has been written on this subject from a standpoint of what’s wrong with the language (and with which I agree quite a lot!), that isn’t, to me, the core of the problem with PHP on the web.

So, I want to talk a bit about some of the more fundamental issues with PHP, which actually goes back well before PHP even existed and is intractibly linked with the way PHP applications themselves are installed and run.

(I will be glossing over a lot of details here.)

Well, that was embarrassing…

So, note to self: library version pinning is a good idea. I should also learn how to properly manage my library version dependencies.

Thanks to @therealtakeshi for bringing this to my attention!
