Pushl v0.2.1 released

Posted Thursday, March 7 at 10:27 PM (9 months ago)

I’ve been working on getting Pushl much more stable and reliable, particularly around a persistent “too many open files” error I was having, which turned out to be primarily due to a fd leak in the caching routines. Oops.

Anyway, there’s also seemingly a problem with how aiohttp manages its connection pool, at least on macOS, so I’ve disabled connection keep-alive by default. However, if you still want to use keep-alive, there’s now a --keepalive option to allow you to do that. I’m finding that it doesn’t really improve performance all that much anyway.

This is feeling beta-ready but I’ll give it a few days for other issues to shake out first.

Pushl v0.2.0 released

Posted Thursday, March 7 at 12:05 AM (9 months ago)

So, I just released v0.2.0 of Pushl. It was a pretty big change, in that I pretty much rewrote all the networking stuff, and fixed some pretty ridiculous bugs with the caching implementation as well.

The main thing is now it’s using async I/O instead of thread-per-connection, so it’s way more efficient and also times out correctly.

And oh gosh, I had so many tiny but critical errors in the way caching was implemented – no wonder it kept on acting as if there was no cached state. Yeesh.

Anyway, I’ll let this run on my site for a few days and if I like what I see I’ll upgrade it to beta status on PyPI.

Pushl v0.1.7

Posted Monday, January 14 at 9:28 PM (11 months ago)

I ended up doing some more work on Pushl and have now released v0.1.7. The major changes:

  • Did a bunch of refactoring to make the code a little cleaner and handle configuration more appropriately
  • Added a configurable timeout for connections (which now defaults to 15)
  • Added a --version option on the command line arguments

Also, some suggested usage ideas below the cut!

Pushl v0.1.6 released

Posted Sunday, January 13 at 8:48 PM (11 months ago)

It’s been a while since I’ve updated Pushl but today I released v0.1.6. It includes the following fixes:

  • Now it supports Pingback as well as Webmention
  • Improved the threading defaults and connection pooling
  • Also checks entries for updates even if the feed didn’t change (in case something changed in the more text or page metadata or whatever)

Anyway, it should just be a pip install --upgrade pushl (or pipenv update) away.

Pushl v0.1.5

Posted Saturday, December 22 at 1:35 AM (a year ago)

While I’m fixing random stuff in Publ, I figured I’d finally fix some problems with Pushl too. Nothing major here, just:

  • Stability: Fixed a bug where feeds that don’t declare links caused the worker to die before entries got processed
  • Performance: Now we use a global connection pool (so connections can be reused)
  • Fixed a minor correctness issue with archive feeds (which actually doesn’t make any difference in the real world but whatever)

Pushl v0.1.3, and a FeedOnFeeds update!

Posted Wednesday, November 28 at 1:18 AM (a year ago)

I just released Pushl v0.1.3, which adds some minor performance optimizations and a bug fix.

Originally I was hoping to have a major performance optimization, in the form of having rewritten Pushl from thread-per-connection to async operation, but unfortunately I ran into a bunch of problems with it. Mostly that I was running into a “too many open files” error and I couldn’t figure out what was causing a descriptor leak. I have the work-in-progress branch online if anyone wants to take a look at it.

Anyway, the reason I went down this route is because I added WebSub subscriber support to my fork of Feed-On-Feeds, which makes it so that WebSub-enabled RSS and Atom feeds will push their updates to your reader instead of having to wait for a polling interval.

You can read more about some of my other thoughts on a blog entry that quickly devolves into a rant, if you’re so inclined.

Pushl 0.1.0 released

Posted Wednesday, October 10 at 10:41 PM (a year ago)

I’ve gotten Pushl to the point that I’m confident in releasing it as a full alpha and having a cron job run it every 15 minutes. Whew.

I’ve also added some h-entry markup to the Publ site templates so that hopefully the notifications appear at least somewhat reasonably elsewhere.

I really need to redo these site templates now that I have a better idea of how they go together. Also the quickstart guide could be a lot better.

Pushl 0.0.1 released

Posted Monday, October 8 at 11:53 PM (a year ago)

I finally got around to releasing a very rough prototype of Pushl to pypi. It only sends out WebSub notifications for now (does anyone even use those?), but I’ll work on actually implementing WebMention soon.

Also, recently someone pointed out to me fed.brid.gy which makes it easy to turn a static site into an ActivityPub source. At some point I’ll experiment with setting up Publ for this; it looks like it’s just a matter of adding a couple of additional route rules to Publ, so that will probably go into an advanced configuration guide if I ever get around to making such a thing. (Or it could actually be added to Publ directly but there isn’t much of a reason for that, IMO.)

Goodbye peewee, hello PonyORM

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.
