@Ericson2314:matrix.orgJohn Ericsonpre planet Nix I was really busy doing other stuff in Nix (and also win work, unrelated to Nix!). Now after words I stick my head up for air and see --- oh shit, new Nixpkgs is almost here, and we're really behind20:47:46
@Ericson2314:matrix.orgJohn EricsonI've put all the CA and dyn drv and other personal priorities on hold to get this stuff sorted20:48:02
@raitobezarius:matrix.orgraitobezarius
In reply to @roberthensing:matrix.org
not that I know of. Where would that be?
latest I have in mind is that output path calculation change with fetchTree and file:// between 2.19 and 2.24, I'd need to look again in my notes
20:48:23
@Ericson2314:matrix.orgJohn Ericsonget the headers, the package config, the nixpkgs legibility, and other things that need to get bumped sorted20:48:25
@raitobezarius:matrix.orgraitobezariusbut I'd appreciate if this could be tested before Lix has to discover it :P20:48:40
@Ericson2314:matrix.orgJohn Ericsonit's not the ideal timing for sure! No disagreement from me there!20:48:59
@Ericson2314:matrix.orgJohn Ericson raitobezarius: I recall some Lix patch that made it respect the fetching equivalent of outputHashMode 20:49:21
@Ericson2314:matrix.orgJohn Ericsonthat sounds like something we should have20:49:26
@Ericson2314:matrix.orgJohn Ericsonit didn't look like a regression20:49:37
@Ericson2314:matrix.orgJohn Ericsonbut respecting the thing does look more correct than not20:49:50
@raitobezarius:matrix.orgraitobezariuswell, this was a bug that was fixed but caused output path calculation changes which goes against the contract of reproducibility20:50:10
@raitobezarius:matrix.orgraitobezariusthis meant that who had in their cache had to cache bust everything20:50:21
@raitobezarius:matrix.orgraitobezarius* this meant that who had this in their cache had to cache bust everything20:50:27
@emilazy:matrix.orgemily there's a reason we ended up on 2.18 for so long and rushing while waving away concerns isn't going to fix it :( if we want to keep the versions synced then there needs to be work to rebuild the trust that concerns will be taken seriously and regressions handled. those concerns right now include timing relative to the freeze, breaking patches/flag overrides with zero deprecation period for one of the most critical packages,the packaging rewrite being understood by maybe 3 people in the world, and the fact that all this is being declared by fiat with no prior clarity 20:50:33
@raitobezarius:matrix.orgraitobezariusthe problem is not the bug the problem is that output path calculation changes are very visible especially if they do change a lot of paths20:50:46
@Ericson2314:matrix.orgJohn Ericsonlibfetchers is full of crap that roberth and I have yet to wade through 🤷20:50:50
@Ericson2314:matrix.orgJohn Ericsonin all forks20:50:53
@raitobezarius:matrix.orgraitobezariusnot arguing about the bug qualification20:51:00
@Ericson2314:matrix.orgJohn Ericsonyou won't find me disagreeing about that!20:51:03
@emilazy:matrix.orgemilythree days ago a member of the Nix team said he couldn't understand the packaging. ten hours ago another member announced in the release thread that the plan was to ship 2.24 by default before editing it20:51:14
@raitobezarius:matrix.orgraitobezariusarguing about our responsibility to ensure that we don't unnecessarily cache bust and that we discuss potential cache busts before sending them in releases20:51:23
@raitobezarius:matrix.orgraitobezariusno matter if they are bugs or unsound20:51:35
@emilazy:matrix.orgemilymaybe all those concerns were resolved within the past few days? but even if so it would be premature to launch into a bump given that20:51:39
@Ericson2314:matrix.orgJohn EricsonI dunno what that editted thing was about because I woke up around 11 pm EDT20:51:43
@Ericson2314:matrix.orgJohn Ericson raitobezarius: I am not even arguing with you 20:52:01
@emilazy:matrix.orgemilyhow can Nixpkgs and Nix communicate if y'all aren't even on the same page about packaging and defaults?20:52:04
@Ericson2314:matrix.orgJohn Ericsonstop being slimy20:52:05
@Ericson2314:matrix.orgJohn Ericsonlix has a fix, it ilooks good20:52:14
@Ericson2314:matrix.orgJohn Ericsonwe're happy to take it20:52:18
@Ericson2314:matrix.orgJohn Ericsonthe end20:52:19
