I've been trying to get buildah working in forgejo-runner for building container images on CI, and it's been a frustrating process. There are some posts around the web about this, but nothing that sums up a working solution that doesn't simply disable all security measures. I eventually pieced it together with a lot of trial and error, so here's a summary to hopefully save somebody else (or me in…

Some irresponsible and/or malicious crawlers brought down lv2plug.in this week. To avoid this happening again, I've removed lv2plug.in/git entirely, since it was the only dynamic thing at that domain. There used to be a cgit interface to the repositories there, but I doubt anyone will miss this anyway. Everything else should now be back up and working as before.

My simple single-plugin LV2 host, Jalv , isn't quite sure whether it's a developer utility or polished user program, but in any case, it had become stale in the past few years and needed an update. Most of those changes are internal and only interesting for those who use it as a basis for larger systems. The internals have been largely rewritten to support various things, but this post isn't about…

My previous post, “Improving LV2 Discovery Performance” , described adding an option to lilv that controls whether an additional index is maintained for loaded LV2 data. While testing those changes for release, I discovered a few things (like lv2lint ) that break without the index, which convinced me that disabling it by default wasn't the right decision. So, I'm instead enabling it by default,…
LV2 plugins (and other data, like presets) are discovered by parsing Turtle files installed in various bundle directories. If the host only needs to know which things are installed, then only manifest.ttl files need to be loaded. That takes only a fraction of a second (60 ms on this machine, which has 897 plugins installed), but if the host needs more information (like the plugin's label or what…
I haven't been sure what to do about the software pages here for quite a while. Most of them were essentially just stale versions of the README files from their projects, and for better and worse, most of the projects I maintain are libraries that don't have as much of a need for a homepage as user-facing software. It's easy to just ignore things that don't really matter in day-to-day work, but…
I don't suppose inactivity from me will be terribly surprising to anyone after the past several years. Still, since I was working on emptying my bug-fix and maintenance queue, making releases, and finally getting to some significant forward progress again, an update: Unfortunately I got violently ill last week with some horrible flu-like thing, the worst I've ever had (and I'm a COVID casualty, so…

As most git users are aware, the default branch name in git changed from master to main a while ago. Since I maintain projects created both before and after this change, some maintenance tasks have become more difficult to automate as a result (and I'm a sucker for consistency). I put off dealing with this because I was planning to make master branches disappear at the same time APIs are broken,…

One of the many programming side quests I embark on from time to time is finding the best way to do compile-time configuration in C and C++ code. This is one of those characteristically C things that most projects need to do, but that has no well-established best practice. What you can find is all over the place, and often pretty half-baked just to suit the particularities of the “official” build.…
