# Why Publ won’t support magic auth links

Posted Friday, October 25 at 5:36 PM (4 months ago)

Since adding user authentication to Publ, I’ve been thinking of ways of allowing people to subscribe to sites from feed readers while getting their own native authorization, so that people can see entries directly in their readers rather than needing the clumsy mechanisms of unauthorized placeholder entries.

Out of the box, Publ authentication does support a shared cookie jar; if you can provide your cookies to your feed reader in some way, then things will Just Work. Unfortunately, I don’t know of any feed readers that actually support this, at least not easily. (Back when most browsers had a feed reader built-in this was a lot simpler. But time marches on.)

The two mechanisms which seemed most promising are AutoAuth and “magic links,” where users get signed URLs that come pre-authenticated and show the full authorized content for that user. AutoAuth is still in a draft phase that’s stuck in a chicken-and-egg situation (and also requires a lot of buy-in to IndieWeb protocols, which is still a pill too large to swallow for most of the folks who follow my blog), so magic feed links seemed like the best path forward.

I even got so far as to draft out an implementation, but there’s a few bad issues with it which just made me opt not to.

# Reblob!

Posted Sunday, April 28 at 2:39 AM (10 months ago)

It’s been a while since I’ve worked on IndieWeb stuff, but I finally got around to releasing an extremely preliminary version of reblob, a little commandline thingus to make this stuff easier. Eventually I’ll also have a server-based version here, at least as an example.

# Pushl v0.2.4, now with a proper user-agent

Posted Friday, March 15 at 5:29 PM (11 months ago)

While trying to figure out some weird access patterns on the day-job site I had the realization Pushl wasn’t actually specifying a user-agent, so it was just coming through as the generic aiohttp one, which isn’t very friendly.

Now it sends a reasonable user-agent by default, and this can be overridden by the --user-agent flag if you want to for your own analytics or whatever.

Oh, and I had quietly released 0.2.3 a few days ago; there were just some minor internal changes to logging and also declaring Pushl as beta, rather than alpha, software.

# Pushl 0.2.2

Posted Sunday, March 10 at 6:25 PM (a year ago)

I’ve done a bunch more work on Pushl to try to get it more stable. In particular, I’ve made it so that it will only recurse into feeds that are on domains that were declared in the initial requests, and I seem to have cleared up some cases which were causing it to hang and also added a global timeout which will, hopefully, prevent it from hanging indefinitely.

I do wish I could figure out what is causing the hangs when they do happen though. Oh well. Some discussion of the issue below the cut.

# Pushl v0.2.1 released

Posted Thursday, March 7 at 10:27 PM (a year 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 (a year 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.

# v0.3.19, now with extra tagging goodness!

Posted Monday, March 4 at 3:47 PM (a year ago)

I’ve released Publ v0.3.19, which now finally has a tagging system, which is only one of the oldest issues that was still open.

Here’s a list of what’s been added or changed since 0.3.18:

### Credits

I want to thank Karina Antonio for implementing image cropping.

# v0.3.18, now with better asset management!

Posted Wednesday, February 27 at 9:38 PM (a year ago)

I’ve just released v0.3.18, with the following changes:

• Add date grouping properties to entry
• Add a pages property to view
• Provide the current category object to the error handler
• Support linking to non-image/non-entry local files
• Added, then removed, some performance micro-optimizations that only caused problems

More details about the major changes below!

Update: I released a hotfix as 0.3.18.1 because there was a last-minute bug that snuck in while I was trying to silence a new pylint error. Oops.

# An early-alpha Movable Type importer

Posted Wednesday, February 20 at 3:42 PM (a year ago)

For those folks who want to import their content from Movable Type over to Publ, I’ve finally gotten around to writing an importer. Currently it only attempts to convert entry content and category metadata, and only using SQLite-formatted database dumps.

See its README.md for the (incredibly rough) usage instructions.

Eventually I want to try to automatically convert templates from MT’s scripting language to Jinja-Publ templates, although there’s a bunch of stuff that’s going to be difficult to port across and a lot of stuff is just plain not feasible to even try, so don’t expect that to become a major thing any time soon.

# v0.3.15 Released (finally!)

Posted Wednesday, February 13 at 6:20 PM (a year ago)

It’s been a while since I’ve had a chance to work on Publ, but the great thing is that I actually had a reason to work on it for my day job. Which is to say I’m finally being paid to work on Publ. ;)

Changes since 0.3.14:

• Add requirement for Arrow 0.13.0 (issue 41)
• Fix a dumb tpyo that was the cause of issue 158
• Don’t rewrite DRAFT files; fixes 137
• Move sample-site files back to the library repo rather than in the doc repo
• Fix the way we map malformed category URLs (issue 156)
• Update upstream library versions
• Move version number to publ module
• Allow empty slug-text in entry route (fixes 161)
• Process HTML entries, to finally handle issues 136 and 154.

# Pushl v0.1.7

Posted Monday, January 14 at 9:28 PM (a year 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 (a year 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)

# Embedding webmention.io pings on your site

Posted Thursday, December 20 at 11:14 PM (a year ago)

Are you using webmention.io as your webmention endpoint? Want to get your incoming webmentions displayed on your website?

Well you’re in luck, I wrote a simple-ish script for that. (You’ll probably also want to see the accompanying stylesheet too.) And it doesn’t even require that you use Publ – it should work with any CMS, static or dynamic. The only requirement is that you use either webmention.io or something that has a similar enough retrieval API.

I wrote more about it on my blog, where you can also see it in use. For now, I’m just going to use the sample site repository to manage it (and issues against it).

It’s MIT-licensed, so feel free to use it wherever and however you want and to modify it for your needs. I might improve it down the road but for now it’s mostly just a quick itch-scratching hack that does things the way I want it to.

# v0.3.11

Posted Saturday, December 15 at 1:08 AM (a year ago)

v0.3.11 is now released, with the following changes:

• A more complete fix for how to handle image sets and inline images with respect to paragraphs
• Better cleanup for spurious empty paragraphs
• Improved internal entry link handling

Detailed descriptions of the changes are below.

# v0.3.9 Released

Posted Wednesday, November 28 at 3:33 PM (a year ago)

This entry marks the release of Publ v0.3.9. It has the following changes:

• Added 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.

# 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.)

# v0.3.3 - now with ETag and Last-Modified

Posted Monday, October 1 at 11:16 PM (a year ago)

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.
