Didn't I hear from mpickering in some talk recently that profiling mode is almost never what you want nowadays? You already get a bunch of great stuff "for free", and then when you want more you still don't usually want -fprof. I could be remembering this all wrong though I'm told that nowadays you can also get flamegraphs without profiling builds | 20:02:09 |
| John Ericson | alexfmpe: you don't have perms on that library do you? :) | 20:04:21 |
| alexfmpe | Huh? Which lib | 20:08:28 |
 maralorn | Yes, but they are often relatively useless when not all your dependencies are compiled with -finfo-table-map. | 20:09:20 |

 MangoIV | Yeah I know. :/
A third output maybe? Build multiple ones? Compression also improves it. Did you try it out with compression?
| 11:55:29 |
| maralorn | I didn’t. | 12:20:04 |
| maralorn | I think the way to go would be to first figure out a way to provide a third output and then at some point default the profiling output to off and the info table output to on. | 12:21:05 |

 sterni | compression likely means incorrect reference tracking | 13:23:14 |

 Wolfgang Walther | cachix fails to build for darwin on staging-next and it's a blocker. https://hydra.nixos.org/build/312752225 | 12:40:45 |
| maralorn | Seems to only need a restart? At least the log link forwards to a successful build. | 12:53:23 |
| Wolfgang Walther | It does not for me. | 12:54:32 |

| maralorn | Ah, I thought the lowest build is the most relevant. | 12:56:46 |
| maralorn | Well, that error looks terrible. | 12:57:34 |

also cc Robert Hensing (roberth) likely something with the hercules-ci libs? | 08:02:24 |
