Hi Mark, How do you notice when a change breaks something else? You so frequently notice these things, it almost seems like you're omniscient! Do you have an automated mechanism for doing this, or are you manually checking things frequently?

Here's an example of what I mean: Mark H Weaver writes: > Hi Tobias, > > me@tobias.gr (Tobias Geerinckx-Rice) writes: > >> nckx pushed a commit to branch master >> in repository guix. >> >> commit 906f1b48e20a032c22a164c89f9e8862ab2bec7a >> Author: Tobias Geerinckx-Rice >> Date: Wed Jan 3 09:01:53 2018 +0100 >> >> gnu: luajit: Update to 2.1.0-beta3. >> >> * gnu/packages/lua.scm (luajit): Update to 2.1.0-beta3. >> [source]: Remove symlinks patch. >> * gnu/packages/patches/luajit-symlinks.patch: Delete file. >> * gnu/local.mk (dist_patch_DATA): Remove it. > > This seems to have broken the 'love' package, which uses luajit. > > https://hydra.gnu.org/build/2488685 > > Would you be willing to investigate? > > Mark > -- Chris
