 WeetHet | Now that infra supports lockable tarballs for channel releases, what do you think about adding a channel:name flakeref pointing to channels.nixos.org/name/nixexprs.tar.xz?
Is it too much coupling?
| 20:09:03 |
 leona | I (not part of the nix team nor associated with nix development) wouldn't like the name "channel:" for this, as the concept of a channel is far greater than Nixpkgs and therefore anything channel.nixos.org offers | 20:39:51 |

 dramforever | even though it's debatable whether it would be good to add it to flakes, there is precedence for e.g. channel: urls already being that | 01:42:03 |

| WeetHet | Yep, for example:
nix-instantiate channel:nixpkgs-unstable hello --log-format multiline
[4.4/30.4 MiB DL]
downloading 'https://nixos.org/channels/nixpkgs-unstable/nixexprs.tar.xz'

Let's see what people think | 14:07:35 |

 fzakaria | Whose familiar with SourceAccessor in CppNix ?
We were seeing divergent failures for missing files; I was seeing "FileNotFoundError" and Shahar "Dawn" Or (mightyiam) was seeing "SysError" (although not in unit tests).
We've rebased and it's gone away but it's bugging me not knowing the difference.
| 15:58:50 |
| fzakaria | My best guess -- is his Nix build was picking a different SourceAccessor. Mine seemed to be picking PosixSourceAccessor. | 15:59:27 |

 John Ericson | Eelco: if (settings.buildHook.get().empty() || !worker.tryBuildHook || !useDerivation) return rpDecline; | 19:31:48 |
| John Ericson | do you know what !useDerivation is needed? | 19:31:56 |
| John Ericson | this comes from 1511aa9f488ba0762c2da0bf8ab61b5fde47305d | 19:32:25 |
| John Ericson | what confuses me is that I thought we would convert to using in-memory derivations with the build hook | 19:33:06 |
| John Ericson | i.e. we computed the inputs closure, and then we send that to the build hook | 19:33:17 |
| John Ericson | and thereafter we're working in-memory | 19:33:25 |
| John Ericson | so I don't get what this condition accomplishes, and yet if I remove it, tests hang | 19:33:53 |
| John Ericson | does remote building even work with an eval store? | 23:00:49 |

 jade_ | i just released https://jade.fyi/blog/misadventures-in-dtrace/ and it occurs to me that it might be prudent to give y'all a heads-up of our plight with MonitorFdHup and to suggest potentially picking our macOS platform-specific implementation of it | 02:23:25 |
