dbus 1.2.23 no longer supports GHC 8

[elldritch]

This is caused by #55 bumping the version of Template Haskell. See also: build failures on Hackage.

I think the right solution is that either the version range on template-haskell needs to be loosened, or the supported versions of base need to be tightened to exclude older GHCs.

template-haskell had a non-backward-compatible change, so the code wouldn't work with both new and old versions anymore. Does hackage use some base-based heuristics to detect GHC versions, ignoring all other bundled packages? There is no technical reason to tighten base bound but I can do it so that docs will be built.

[elldritch]

I'm not sure, but my guess is yes since I've seen other packages that only support newer versions of GHC that specified base constraints and whose documentation properly built.

I think there's also a manual process for uploading documentation, although I can't remember exactly how it works off the top of my head.

Released 1.2.24 with base >= 4.16

Hmm, it looks like docs are still failing to build: https://hackage.haskell.org/package/dbus-1.2.24/reports/1. I'm not sure what's going on here or how to convince Hackage to build these docs - AFAICT it seems to be trying to build docs on a machine that's not running a supported version of GHC.

I find it sad that support for older GHC was dropped this way. How isolated is the backwards breaking change? Couldn't we simply use CPP to support older versions?
