 Vladimír Čunát | thunderbird keeps timing out again on aarch64-linux. Weird. For some time this looked fixed. | 12:28:01 |
 Ihar Hrachyshka | @vcunat:matrix.org: was there a history of aarch64-linux timing out? (Not Darwin.) | 12:48:21 |
| Vladimír Čunát | It should've been fixed by https://github.com/NixOS/infra/pull/1100 | 12:49:33 |
| Vladimír Čunát | And now it looks the same as before that fix, IIRC. 3h thunderbird build, timing out. | 12:50:02 |
| Vladimír Čunát | Apparently we're mis-applying this config again. | 12:50:40 |
 K900 | Is it possible the new runner is ignoring silent-timeout | 12:51:16 |
| Vladimír Čunát | Actually, why do we configure this on the queue-runner-dev and not on the builders themselves? 🤔 | 12:52:31 |
 hexa | infra: because there is only an option on the queue-runner | 12:54:38 |
| hexa | hydra: no idea | 12:54:41 |
| hexa | we kinda regressed the the silent timeout from 2 to 3 hours on linux, because we couldn't set it per builder any more | 12:55:07 |
| K900 | Maybe we should just set meta.maxSilent | 12:55:39 |
| K900 | It looks like the runner understands it | 12:55:48 |
| K900 | (at a glance) | 12:55:50 |
| Vladimír Čunát | The very long linking in thunderbird is also not optimal wrt. utilization of big-parallel machines, but these timeouts are a way worse issue. | 12:58:30 |
| hexa | linker times went up for firefox, too | 12:59:21 |
| K900 | It's doing fatLTO, right? | 12:59:28 |
| hexa | no idea | 12:59:54 |
 emily | do linking in a separate derivation | 13:00:05 |
| emily | surely firefox is ThinLTO? fat feels overkill | 13:00:30 |
| hexa | https://github.com/mozilla-firefox/firefox/commit/e413a865c3f97bd9bc494373c470a088509ac293 hrm | 13:02:07 |
| hexa | maybe in 155 :D | 13:02:21 |
| hexa | https://bugzilla.mozilla.org/show_bug.cgi?id=2045567 | 13:02:49 |
| hexa | 154* | 13:03:17 |
| hexa | so we'll have a full ESR cycle without it | 13:03:25 |
| hexa | Redacted or Malformed Event | 13:03:34 |
| Vladimír Čunát | Maybe we could pick it. | 13:04:54 |
| Vladimír Čunát | By glancing at the commit it doesn't really look relevant to firefox version. | 13:05:14 |
| Vladimír Čunát | * Maybe we could pick the patch. | 13:06:00 |
| Vladimír Čunát |
60% improvement on build time on opt-nightly
| 13:07:39 |
| emily | FatLTO is very painful, I think for memory usage as well. so it makes sense to me | 13:09:24 |
