This entry marks the release of Publ v0.3.9. It has the following changes:
more_text and related functionality to image sets (an example being visible over here)
- Improved and simplified the caching behavior (fixing some fiddly cases around how ETags and last-modified worked, or rather didn’t)
I also made, and then soon reverted, a change around how entry IDs and publish dates were automatically assigned to non-published entries. I thought it was going to simplify some workflow things but it only complicated the code and added more corner cases to deal with, all for something that doesn’t actually address the use case I was worried about. So never mind on that.
(What happened to v0.3.8? I goofed and forgot to merge the completed
more_text et al changes into my build system first. Oops.)
See below for more on the caching changes.

I’ve released v0.3.7, which just fixes a few issues around transaction management and overall indexing performance. Namely:
- The indexer locks individual entries as it’s working on them
- If an entry is being worked on, watchdog will ignore it
- Cleaned up a couple of transaction failures that can occur due to PonyORM’s optimistic locking behavior

I just released v0.3.6 of Publ, which just allows it to work with databases other than SQLite. In particular this is part of testing more advanced heroku deployment options.
Right now I’m primarily focusing on improving the documentation, especially the quickstart guide, since people are finally showing interest in Publ but aren’t quite sure where to begin!

I’ve now released v0.3.5 of Publ. Changelog:
- Add support for listing deleted entries (accessible via
- Improved how the last-modified/etag reference was determined (also fixing a nasty bug where a site might crash if a file is deleted)
- Fixed a minor shaping bug
I’ve also updated the sample site templates with all of the changes that have happened since, uh, June, and also included some sample content so it’s easier to get started with it.

Turns out I never actually tested the
If-Modified-Since handler, because if I had I’d have seen the glaring exception it threw.
Oh well, that’s fixed now. I think.

I’ve started working on Pushl in earnest now, and one thing that was really bugging me about this is that anything which polls feeds and entries would really benefit from having client-side cache control working. Which was a big missing feature in Publ.
Well, I finally implemented it, and I’m pretty happy with how I did it.
The short version: for any given view it figures out (pessimistically) what’s the most recent file that would have affected the view (well, within reason; it only looks at the current template rather than any included templates, which is pretty difficult to do correctly) and uses that to generate an ETag (via metadata fingerprint) and a Last-Modified time (based either on the file modification time or the time the entry was actually published).
There’s probably a few corner cases this misses but in general this makes client-side caching of feeds and such work nicely.

I found a few more annoying bugs that were shaken out from the whole PonyORM transition, as well as a couple of bugs in the new shape functionality. There’s probably a few more of these bugs lurking in the codebase (I mean, in addition to the existing bugs I know about), but here’s what’s changed:
- Image shape bugs:
- Fix some
FileNotFound handling on images (so
shape errors propagate correctly)
class work correctly per the documentation
- PonyORM bugs:

Did you know that CSS3 has a style called
shape-outline? It’s pretty neat, it makes it so that a floated object gets a shape based on the alpha channel of its specified image. But it’s kind of a pain to set up; in plain HTML it looks something like this:
<img src="/path/to/image.png" width="320" height="320"
and if you want a different shape mask for your image than its own alpha channel, you have to do a bunch of stuff like making sure that the image sizes are the same and whatever.

Version 0.3.0 is now released, with the change from peewee to PonyORM.
As a result of this change you’ll have to do two things to your config file:
- The database configuration format has changed slightly
- Any existing databases have to be manually deleted/dropped/etc.; unfortunately PonyORM doesn’t provide a mechanism for deleting tables not under its control
Everything else should work identically as before.
Posted Wednesday, September 19 at 2:27 AM (a year ago)
For a number of reasons, I have replaced the backing ORM. Previously I was using peewee, but now I’m using PonyORM. The primary reason for this is purely ideological; I do not want to use software which is maintained by someone with a track record of toxic behavior. peewee’s maintainer responds to issues and feature requests with shouting and dismissive snark; PonyORM’s maintainer responds with helpfulness and grace. I am a strong proponent of the latter.
PonyORM’s API is also significantly more Pythonic, and rather than abusing operator overloads for clever query building purposes, it abuses Python’s AST functionality to parse actual Python expressions into SQL queries. Seriously, look at this explanation of it and tell me that isn’t just amazing.

Earlier today I pushed v0.2.2, which was a minor configuration fix for the markdown library to support table syntax.
Then I pushed v0.2.2.1 which was another configuration fix to fix that fix (oops).
Then in deploying updates I upgraded to Python 3.7, and promptly discovered that Publ doesn’t actually work on Python 3.7, so just now I fixed that, and released the fixes as v0.2.3.

Just a couple of minor fixes in this release:
Posted Friday, July 6 at 3:57 PM (a year ago)
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)

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:
- Figuring out how to always make IDs get assigned in an idempotent manner (hard to do correctly)
- Don’t run on Heroku so the assignments persist between executions (easy)
- 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.

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

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
- 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
- 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)
Posted Sunday, May 27 at 5:22 PM (a year ago)
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
- 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

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
view.link() now allows overriding
- FEATURE: You can now mark an entry with an
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
first which made no sense anyway

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
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!
Posted Saturday, May 19 at 12:00 AM (a year ago)
Today I added two new useful features:
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?
