 emily | reno doesn't use nix-darwin, and maybe the Nix installation is old? | 00:10:59 |
| emily | no, wait, that doesn't explain it, since it used to be 4096 still. | 00:11:21 |
 Artturin | What if in one of the places that require the ulimit to be set you set it to the linux number instead of 4096 | 00:11:29 |
| emily | to check if too-high values are getting capped, or? | 00:12:44 |
| Artturin | If setting it above the limit is interpreted as 1 or something | 00:13:21 |
| Artturin | well it shouldn't be 1 because then all builds would fail | 00:13:43 |
| Artturin | hmm | 00:13:46 |
| Artturin | How does ulimit for you show the number above the limit | 00:14:10 |
 @paparodeo:matrix.org | nb -E '(import <nixpkgs>{}).runCommand "foo" {} "ulimit -n"'
this derivation will be built:
/nix/store/15zc62jpxd2sszpaidzcsfxs4clpf4jc-foo.drv
building '/nix/store/15zc62jpxd2sszpaidzcsfxs4clpf4jc-foo.drv'...

How does ulimit for you show the number above the limit so ulimit -n 122881 actually works on macOS 15, I guess it changed since 10.12. and it's reported as 122881. but presumably capped as reno described seeing | 00:15:14 |

I take it you didn't observe black going from failing to reliably passing with your PR, right? I'm wondering if actually the problem is just that Hydra has a messed up setup. | 00:15:56 |
| Artturin | I didn't really look in to it or monitor it | 00:16:27 |

| @paparodeo:matrix.org | I had also assumed that the limit was 256 | 00:16:56 |
|  @janne.hess:helsinki-systems.de left the room. | 00:20:05 |
| emily | the good news is that the Go compiler derivation runs ulimit -a. | 00:20:06 |
