@sternenseemann:systemli.orgsterni (he/him)the thing is also that the Haskell opentracing implementation seems to be maintained still (had a release last year) and does not actually depend on any of the upstream opentracing packages.13:43:49
@sternenseemann:systemli.orgsterni (he/him) so it does not seem to me like it needs to be removed 13:44:01
@eveeifyeve:matrix.orgeveeifyeveBut the protocol has been deprecated/archived, so it will not work.13:48:57
@eveeifyeve:matrix.orgeveeifyeve* But the protocol has been deprecated/archived for open telemetry, so it will not work.13:49:40
@eveeifyeve:matrix.orgeveeifyeveSee https://github.com/opentracing/specification/issues/16313:50:33
@eveeifyeve:matrix.orgeveeifyeve* See https://github.com/opentracing/specification/issues/163 for more info13:50:38
@sternenseemann:systemli.orgsterni (he/him)well i mean if you still have an opentracing compatible server and client it will continue to work the same as it used to13:55:51
@eveeifyeve:matrix.orgeveeifyeveLightstep has been deprecated/archived so that can be removed. I have also opened up an issue upstream: https://github.com/kim/opentracing/issues/5513:56:28
@sternenseemann:systemli.orgsterni (he/him)i agree it doesn't make sense to keep maintaining this stuff, but it's also not like anything bad is going to happen if it's still around13:56:45
@eveeifyeve:matrix.orgeveeifyeveBut again in nixpkgs, we should not keep stuff that seems like it will go unmaintained in nixpkgs.14:06:02
@eveeifyeve:matrix.orgeveeifyeveOne reason to remove the opentracing stuff is unmaintained, https://github.com/NixOS/rfcs/blob/master/rfcs/0180-broken-package-removal.md#unmaintained-packages14:37:36
@sternenseemann:systemli.orgsterni (he/him)that definition doesn't even have anything to do with upstream maintenance15:54:51

@maralorn:maralorn.demaralorn sterni: If we switch to nightly that means going to ghc 9.12, right? 10:35:06
@maralorn:maralorn.demaralornIs that safe in regards to the whole miscompilation thingy?10:35:22
@maralorn:maralorn.demaralorne.g. do we maybe want to wait for 9.12.4?10:35:36
@sternenseemann:systemli.orgsterni (he/him)We patched that in 9.12.3, but we could also wait for 9.12.410:35:48
@sternenseemann:systemli.orgsterni (he/him)Maybe it is sensible to wait for the next HLS release (which is coming soon right?) and the update10:36:47
@maralorn:maralorn.demaralornI don’t know. I am not aware of immediate plans.10:41:29
@maralorn:maralorn.demaralornIt seems likely that they would want to make a release after 9.12.4 to provide binaries.10:41:48
@maralorn:maralorn.demaralornBut I also wouldn’t be other than from it being discussed on the hls matrix channel.10:44:38
@sternenseemann:systemli.orgsterni (he/him)I just saw new versions of lsp and lsp-types so I assumed that was the reason10:44:58
@sternenseemann:systemli.orgsterni (he/him)in any case, most stuff I had on my mind we can do with LTS is done, what remains are things like pandoc 3.9 which are probably best addressed by jumping to nightly10:46:42
@sternenseemann:systemli.orgsterni (he/him)Also if anyone is interested in trying out 9.12.4-rc1 https://github.com/NixOS/nixpkgs/pull/50010811:10:27
@sternenseemann:systemli.orgsterni (he/him) alexfmpe: this was on darwin, right? https://github.com/NixOS/nixpkgs/pull/497811#issuecomment-4019565283 17:34:15
@alexfmpe:matrix.orgalexfmpeaaah yeah22:10:03
@alexfmpe:matrix.orgalexfmpeI forgot that threw off regen script22:10:13
@eveeifyeve:matrix.orgeveeifyeveI experienced this as well in this pr: https://github.com/NixOS/nixpkgs/pull/499983#issuecomment-406291605822:39:11
@eveeifyeve:matrix.orgeveeifyeve* I forgot to mention this, It's not just that pr is linked it's across globally: https://github.com/NixOS/nixpkgs/pull/499983#issuecomment-406291605822:40:10
