 emily | yeah | 01:25:06 |
| emily | can always do both this and raising FD_SETSIZE | 01:25:17 |
 Randy Eckenrode | I got SwiftPM working correctly in a dev shell to build my Advent of Code solutions from 2022 (which were written in Swift). The resulting binary correctly targets macOS 13 per the platforms configuration in Package.swift. | 01:27:55 |
| Randy Eckenrode | I guess next is splitting out the stdlib. I’m not sure what else is left other than maybe seeing if I can do some kind of cursed prebuilts thing. | 01:28:15 |
 Ihar Hrachyshka | if I were to go with alloc (which I will), I'd do raising only if I notice perf degradation. (atm it smells like premature optimization) | 01:28:17 |
| Randy Eckenrode | (And building on Linux.) | 01:28:18 |
| emily | yeah I expect the syscall overhead is much higher than allocation anyway. | 01:30:40 |
| emily | given the nature of the call | 01:30:51 |
| emily | I hope they require a new enough C standard for the sizeof-struct-with-runtime-array-size thing to work. (sizeof (int32_t) * nelems could have padding issues in theory I think.) | 01:31:59 |
| Ihar Hrachyshka | ok I don't know much about it. what would be "new enough C standard"? | 01:33:08 |
| Ihar Hrachyshka | it's gnu99 as per meson.build | 01:34:03 |
| Ihar Hrachyshka | * it's gnu99 as per meson.build | 01:34:08 |
| emily | I believe it's okay in C99+ so should be fine | 01:34:39 |
| Ihar Hrachyshka | besides this select exhaustion issue, I have two more patches related to nixpkgs VMs running on darwin. These are waiting for reviews for quite a while.
https://github.com/NixOS/nixpkgs/pull/440579 - keeping VM gcroots alive while VM is running (on Lix for now)
fix dns resolution for some vpn scenarios; enabling local dns resolver for linux builder: https://github.com/NixOS/nixpkgs/pull/434893

 flokli | emilycan you bonk https://github.com/NixOS/nixpkgs/pull/474675 for now? | 23:15:10 |

 Nadia | so I'm not sure if this is actually a nix-related issue at all, but has anyone had problems with processes in the terminal just kinda hanging up after a while? Specifically it happens with the fish shell from nixpkgs, it simply gets stuck forever during launching it, not even lldb can pause or kill the process | 06:18:40 |
| Nadia | on macOS 26.2 | 06:19:01 |
| Nadia | it's kinda the same symptoms as on linux when you get I/O errors that cause processes to become stuck and completely unkillable | 06:28:02 |
 kdn | How can I get foot.terminfo into darwin? | 16:14:48 |
| kdn | I'm getting a weird error:
/nix/store/yzhl36k6yxfafrvddhqjbwzvmwlyx4iq-stdenv-linux/setup: line 1828: wrapProgram: command not found when building a custom linux-builder on darwin
The file doesn't even have 1828 lines (there are 1818)
Any ideas?

| kdn | don't really have any idea how to debug it, the error seems to come from some underlying script that i don't know how to find | 19:25:51 |
 Winter | can you share what you’re trying to build? | 19:30:17 |
| kdn | let me tag a wip commit and submit then | 19:32:05 |
| Winter | i forget bash’s behavior off the top of my head but the line thing might be a misnomer | 19:33:44 |
| Winter | easier to tell if i can see the expression | 19:33:53 |
| kdn | this is the change I'm doing, I will maybe revise whether I need that custom module system at all there for the builder (it's nice to set everything up exactly the same way as all my other modules), I don't think anything that is not enabled in my set of modules would do anything funny | 19:40:18 |
| kdn | I'll try identify the change thta makes it break tomorrow, gotta run now | 19:41:43 |
| Winter | why are you vendoring the whole linux builder stuff? | 19:42:50 |
