How many levels of plug-in can you find?

It’s probably going to be quiet for at least a few days because of the Christmas holiday, though I’ll of course have the normal weekend features up.

In the meantime, here’s something to ponder: this post about tmux and plugins for it led me to thinking about plugins in general.  The pkg system is sort of a plugin scheme for BSDs, much like apt for Debian, yum, etc.  Each language has its own libraries to load and plugins to manage past that, like Perl’s CPAN.  Nowadays, applications have their own plugins.  For instance, a system with WordPress installed with PHP installed with PHP plugins required with WordPress plugins that also require given PHP libraries.  WordPress manages keeping itself and its plugins up to date, but not the underlying PHP installation.   You can get something similar with Perl along with the Perl-specific package updates, through cpanm.  Or, npm, which seems to be its own world of constant flux.

How many levels could this go?  Like running multiple emulators within each other, how many levels of plugin could you achieve?  There’s probably a series of levels proceeding from tedious to barely maintainable to ridiculous.

Signal safety in DragonFly

Some of the larger application sets on DragonFly have had trouble building, and inconsistent problems with that build.  i.e. rust would fail, but in different parts of the build process, every time.  It looks to be a problem with signal interaction, and there’s now much safer ways to do that on DragonFly.

That is going to require a full buildworld/buildkernel if you are on DragonFly-master, 5.7.  Release/5.6 users are unaffected.
