 emily | well, I had some ideas for making it so that they always can :) but which ones are practical, not sure | 15:52:03 |
| emily | at the very least having to explicitly handle it when such a situation arrives rather than being able to sleepwalk into it would be goo | 15:52:22 |

 whispers [& it/fae] | hai. chromium seems to be having issues on staging-next on my system. if i build (well, substitute) chromium on the latest staging-next, trying to run it immediately sigills on my system (x86_64-linux nixos):
~> nix run github:nixos/nixpkgs/521d05a303dcd44e66f27ad94cc244adaabace12#chromium
[0314/233404.245952:ERROR:third_party/crashpad/crashpad/util/process/process_memory_range.cc:75] read out of range
fish: Job 1, 'nix run github:nixos/nixpkgs/52…' terminated by signal SIGILL (Illegal instruction)
whereas nix run github:nixos/nixpkgs/master#chromium launches successfully. this might be a »my system is fucked issue«, but i'm wondering if anyone else can maybe reproduce this? | 03:37:52 |
| whispers [& it/fae] | …and now that i post i remembered there's a nixos test. that indeed does fail, so i don't think it's just a me thing. fun | 03:40:38 |

 dramforever | looks like a strict-flex-arrays violation | 05:38:25 |
| dramforever | https://source.chromium.org/chromium/chromium/src/+/main:base/metrics/persistent_histogram_allocator.cc;drc=854512ccb0f2d89203be1ec15dbea3fb4e31a326
UNSAFE_TODO(memcpy(histogram_data->name, name.data(), name.size()));
// Space for the histogram name will be added during the actual allocation
// request. This must be the last field of the structure. A zero-size array
// or a "flexible" array would be preferred but is not (yet) valid C++.
char name[sizeof(uint64_t)]; // Force 64-bit alignment on 32-bit builds.
| 05:39:04 |
| dramforever | can my laptop build chromium? only one way to find out | 05:44:12 |
| emily | UNSAFE_TODO oh okay | 05:46:18 |
| emily | reassuring words to come across when your browser is crashing | 05:46:38 |
| dramforever | how much disk space does it take to build this thing asking for a friend | 05:49:03 |
| emily | I think it's many gigs to even just check out the repository | 05:50:21 |
| emily | and its several copies of Debian or whatever | 05:50:25 |
| dramforever | i have 622G according to df -lh | 05:51:05 |
| emily | that seems like it should be more than enough | 05:51:40 |
| emily | RAM OTOH… | 05:51:44 |
| dramforever | 32G ram, m1 pro | 05:52:28 |
| dramforever | seems precarious | 05:52:55 |
| dramforever | i have no idea why on earth would this suddenly be a problem now | 05:54:31 |
| emily | I think we enabled hardening for strict flex arrays at some point | 05:58:18 |
| emily | though I don't think "this cycle" recent | 05:58:24 |
