Release v2.4.1 of Ktistec

Eh, I didn't test enough and released v2.4.0 of Ktistec with a few annoying regressions. Release v2.4.1 fixes them! ☹️ 😠 😡 🤬

Fixed

  • Handle edge cases and race conditions in script runner.
  • Reconnect editor autocomplete support.
  • Fix permissions on uploaded files.

Release v2.4.0 of Ktistec

I just released v2.4.0 of Ktistec. This release encompasses a few things that I've been working on for a while: improved support for operating without JavaScript available/enabled and support for running scripted automations.

Except for a few items, Ktistec now works without JavaScript. Obviously, things like WYSIWYG editing of HTML don't work—I plan to add support for Markdown to compensate. Running in Lynx is a stretch, but...

Since the early days, most controller actions supported both text/html and application/json.  I cleaned up support for the latter and have officially documented the Ktistec API in the README.

In addition, I've added support for running bots/automations (prior announcement). The Ktistec server will periodically run any executable script in the etc/scripts directory. These scripts have access to the Ktistec API and can post, follow, share, like, etc. This is experimental and obviously introduces an attack surface, though that shouldn't be a problem on correctly configured hosts.

Here's the full changelog:

Added

  • Support running scripted automations.
  • "Fetch Once" button on hashtag and thread pages. (fixes #108)
  • Support navigation to a post's threaded view. (fixes #108)
  • Add support for post name and summary.

Fixed

  • Improve support for operating without JavaScript available/enabled.
  • Only enforce CSRF protection on "simple" requests.

Changed

  • Replace use of multi-action controller with formaction. (fixes #101)

Other

  • API usability improvements.

I just released v2.3.0 of Ktistec.  It fixes a few bugs introduced in the previous release. In particular, it handles a case I've observed a few times in production where the fetching of followed content hangs. The fix adds a monitor that periodically checks for "running" tasks without a backing fiber and sets socket timeouts to ensure requests eventually terminate (I believe the latter actually fixes the problem, but belts and suspenders...)

I just released v2.2.0 of Ktistec. A lot of code was written but the main user-visible change is streaming timeline updates to the web client using server-sent events.  The back-end pub/sub framework will also make it easier to decouple some components down the road.

I want a visual indicator that new posts are in my timeline. I appreciate that not everyone feels the same way—if there's interest I may make it switchable.

And now, off to #worldcon!

for reasons i don't understand, some restarts of epiktistes result in huge memory usage spikes—reported both by the garbage collector and the operating system. what's interesting is heap size and free memory move roughly in tandem (though the difference isn't constant), which implies that there is free memory, but perhaps it's too fragmented to be useful?

a restart typically fixes the problem...

#crystallang developers… what can you count on being safe to access during a call to #finalize?

i have some class-level state that i’d like to modify via a class variable but even reading values via that variable seems to cause problems that eventually lead to crashes later in the program. (typically index out of bounds during some later garbage collection run.)

Do you know why LavinMQ can handle so many connections and process that many messages?

There are several reasons, but one of them is because developers can understand the library code the application runs.
