 John Ericson | has anyone debugged nix on macOS? | 05:36:03 |
| John Ericson | I coudn't figure it out or my friend 😠| 05:36:12 |
| John Ericson | all sorts of "debugserver not found" | 05:36:19 |
 Mic92 | @Ericson2314:matrix.org: i started last Sunday: https://github.com/Mic92/strace-macos | 09:21:20 |
| Mic92 | Didn't notice anything special, but I still miss my ebpf and it would be cool if they wouldn't have a userland service that slows down everything and make things like https://github.com/Mic92/strace-macos/issues/41 hard. | 09:24:42 |
 fzakaria | wow thats cool | 17:50:45 |
| fzakaria | Doesn't MacOS have DTrace ? | 17:52:06 |
| fzakaria | https://8thlight.com/insights/dtrace-even-better-than-strace-for-os-x
I think the DTrace engineers even brought it to Linux also now too | 17:52:41 |
| fzakaria | so there's eBPF and DTrace | 17:52:45 |
| John Ericson | And right you were talking about that, thanks @joerg:thalheim.io: | 17:53:02 |
| Mic92 | They do have it, but it's not trivial to use and can freeze up your computer: https://lobste.rs/s/q50ecd/strace_macos_clone_strace_command_for | 19:02:13 |

| eveeifyeve | Robert Hensing (roberth): is the sparseNodes already implemented? | 21:51:52 |
 roberth | eveeifyeve: it's not been done yet | 21:53:45 |
| roberth | it may make sense to play around with the idea in flake-compat first | 21:54:38 |
| roberth | it's a more light weight environment for that kind of thing | 21:54:51 |
| roberth | you'd have to generate the sparseNodes structure by hand, but I think it's a good way to explore what actually needs to be in there | 21:55:40 |
| roberth | iirc flake-compat is written with one global context of one lock file in mind. Probably makes sense to make those functions a bit more independent first so that it's easier to turn it into something that works for multiple flake locks | 21:57:40 |
| roberth | so I'm not exactly sure what needs to be in sparseNodes, but my idea is to treat nodes as a dumb storage for pins, ignoring the dependency injection related fields that are in nodes. I don't know if we even want those in the lock file at all because they're basically duplicated info from the easily readable flake.nix inputs. | 22:01:14 |
| roberth | so I think the minimum we need is a mapping from the inputs structure to the nodes names that contain the corresponding pins | 22:02:21 |
| roberth | and then in the final phase we put the pins in sparseNodes directly instead of a string that references the node | 22:02:57 |
| roberth | btw this is about https://github.com/NixOS/nix/issues/7730 | 22:03:23 |
| roberth | Reuse input lock files | 22:03:29 |
