@qyliss:fairydust.spaceAlyssa Rossit's strange because it's reproducible07:51:20
@qyliss:fairydust.spaceAlyssa RossI suppose I'll verify my store07:51:35
@Las:matrix.orgLasHow did you instantiate the derivation?07:51:49
@Las:matrix.orgLasI could try too07:51:50

@qyliss:fairydust.spaceAlyssa RossOkay, so probably is an issue with store corruption07:59:59
@Las:matrix.orgLas Path itself is /nix/store/c6hi0jmy3kp6q58f208chgik77cd8k4p-docurium-0.6.0.drv 08:00:00
@Las:matrix.orgLasThe name is different on mine and yours08:00:24
@qyliss:fairydust.spaceAlyssa Rosshmm that's odd08:00:26
@qyliss:fairydust.spaceAlyssa Ross Las: aha! path '/nix/store/n94g41vg7qdwvz74dsig7lwvdsvjh8g0-ruby2.7.4-ffi-clang-0.6.0.drv' was modified! expected hash 'sha256:1bv0zp692sybrii3c19hydrm7m7yj925bpv449qpcbjg7nmn5dyz', got 'sha256:0ip26j2h11n1kgkz36rl4akv694yz65hr72q4kv4b3lxcbi65b3p' 08:47:12
@Las:matrix.orgLasI wonder if Nix could be made to check the hashes while reading them, i.e. when you make Nix read a derivation, it should check that what it reads matches the hash.08:52:57
@Las:matrix.orgLasIt seems like it would be a minor overhead, since you always read the entire derivation, and hashing is cheap.08:53:14
@Las:matrix.orgLasDoing the same for ordinary store paths would also be nice but would require a FUSE or similar I imagine.08:53:35
@qyliss:fairydust.spaceAlyssa Rossyeah, that's what I was thinking08:54:06

@mic92:nixos.devMic92Is it now planned to switch to mesonbuild for nix? I am following https://github.com/NixOS/nix/pull/3160 but it is not clear to me?20:18:52

@cw:kernelpanic.cafecw (just got delta) changed their display name from cw (not sticky anymore) to cw (got the delta).00:57:52

@Las:matrix.orgLas I don't think there are any plans to switch to it, even if support for it is added, since it needs to be easy to bootstrap. 07:47:50

does meson require python to function? 		07:50:59

Seemingly yeah 		07:53:08
@nixinator:nixos.devnixinatori can see why nix itself, as it's the old chicken and egg problem... needs to be lean and mean when it comes to building itself.07:56:22
@nixinator:nixos.devnixinatorsometimes you just don't want it more than gcc nix.c -o nix ;-)07:58:01
@nixinator:nixos.devnixinatoryou still need a hell of lot of tooling to make that actually work, but you don't need a complete python environment too!!!07:58:49

Autotools is afaik more restricting than python. Have you tried installing autotools, make, etc on windows? 		18:51:38

no because these are unix tools. 		21:51:18
@mic92:nixos.devMic92Autotools is also not really maintained anymore. There was only a few months ago someone paid to do some fixes.21:52:14
