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

Posted Friday, March 15 at 5:29 PM (5 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 (5 months 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 (5 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 (5 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.

v0.3.19, now with extra tagging goodness!

Posted Monday, March 4 at 3:47 PM (5 months 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:

I want to thank Karina Antonio for implementing image cropping.

Tests removed from main site

Posted Sunday, March 3 at 4:29 PM (5 months ago)

I finally got my first contribution to Publ, which is really great, but it led to me finally realizing that putting the smoke tests for the software in the main site wasn’t so great. So the tests have been moved into the library itself, so they’re only really visible to people who are actually working on the code for Publ itself.

Eventually I’ll make a “features” section that demonstrates the features of Publ instead, since some of the tests were used (clumsily) for that purpose.

While I’m here, I figured I’d mention that the day job’s website is now running on Publ. Woo.

v0.3.18, now with better asset management!

Posted Wednesday, February 27 at 9:38 PM (6 months 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.

v0.3.17

Posted Friday, February 22 at 5:01 PM (6 months ago)

Just some little fixes that I put in for the sake of the day job:

  • Fixed the way that get_view() et al parse the parameters, so now you can actually search for entry_type='' or entry_type_not=''
  • Fixed the sort order of recursive category.subcats

Publ v0.3.16

Posted Wednesday, February 20 at 9:45 PM (6 months ago)

Just another minor release of Publ! Mostly bugfixes. Here’s what’s new:

  • Fixed an issue with HTML <img> rewriting with non-lowercase attribute names
  • Fixed a bug with missing entries causing Publ to die when it tried to remove them from the index
  • Added category.root
  • Some code cleanups, especially removing some unneeded backwards compatibility shims for unsupported versions of Python
  • Redirect-To will now resolve link targets

Relatedly to category.root, I’d neglected to add category.breadcrumb to the manual when that functionality went in, and I’ve also added some usage examples, including something useful for fancy navigation bars.

An early-alpha Movable Type importer

Posted Wednesday, February 20 at 3:42 PM (6 months 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 (6 months 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.

Some more information about that last one under the cut!

Pushl v0.1.7

Posted Monday, January 14 at 9:28 PM (7 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 (7 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.

v0.3.14 (happy π release)

Posted Tuesday, January 8 at 11:57 PM (7 months ago)

Version 0.3.14 of Publ is now released!

This update is mostly about image stuff:

  • Fixed a subtle caching bug that affects sites accessible from multiple URLs
  • Fixed the way that size-clamping (max_width et al) work on remote and static images
  • Enable JPEG optimization in the image renderer
  • Add the ability to link to local rendered images in a Markdown link

Also, if you’re using Publ and hosting your repository on GitHub you may have gotten a security warning regarding the version of pyyaml that Publ depends on. Don’t worry, Publ doesn’t actually use the vulnerable code (it’s actually pulled in by one of the utility scripts from the watchdog library, and not used by watchdog itself). Watchdog has an open issue about this and they’re on track to fix it Real Soon Now.

In the future Publ may actually pull in pyyaml itself for the friends-only functionality, but when it does you can be sure it’ll be a current version. :)

Pushl v0.1.5

Posted Saturday, December 22 at 1:35 AM (8 months 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)

v0.3.13 (spoooooky)

Posted Friday, December 21 at 11:29 PM (8 months ago)

Happy solstice! I seem to be finding lots of stuff to fix and improve these days. Huh.

Changes since v0.3.12:

  • Fixed a date display issue on databases other than SQLite
  • Fixed an issue where markup was being emitted in the <og:title> element for OpenGraph cards
  • Fixed a bug which prevented entry files from being moved (a side-effect of the Windows compatibility fixes)
  • Added the ability to override title sort
  • Also added the ability to use anchors on resolved entry links

Embedding webmention.io pings on your site

Posted Thursday, December 20 at 11:14 PM (8 months 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.

v0.3.12: now we do Windows

Posted Sunday, December 16 at 11:36 PM (8 months ago)

Big news: I finally fixed a long-standing issue, where Publ wouldn’t work on Windows due to how Windows uses a different path separator from every other OS on the planet.

(Okay, to be fair, macOS technically does too; internally it has a path separator of : instead of /. But the POSIX API transparently hides that.)

Anyway, I’ve updated the getting started guide accordingly, and now it shouldn’t be any more inconvenient to build Publ sites from a Windows machine as from Linux or macOS.

Also a few other smol bug fixes, like max_width now works correctly on remote images where width isn’t specified.

I’ve also added a bunch more deployment HOWTOs although they’re in a very rough state right now. As always, I welcome assistance in this regard.

Below the cut, some more thoughts on federated identity.

v0.3.11

Posted Saturday, December 15 at 1:08 AM (8 months 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.

v0.3.10 released

Posted Monday, December 10 at 8:37 PM (8 months ago)

Just some bug fixes with view caching and image handling; in particular, remote and static images will now respect max_width and max_height for the sizing, and I fixed the way that inline images work (insofar as now inline images can work).
