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 v0.1.3, 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.
