gchristensen changed the topic of #nixos-dev to: NixOS Development (#nixos for questions) | https://hydra.nixos.org/jobset/nixos/trunk-combined https://channels.nix.gsc.io/graph.html | 18.09 release managers: vcunat and samueldr | https://logs.nix.samueldr.com/nixos-dev
<Enzime> if Hydra kept track of build times, you could estimate a rebuild time for the packages
<Enzime> then tagging could be based on time as opposed to purely amount of packages
<Enzime> as that makes no indication toward their weight/complexity

<niksnut> Hydra does keep track of build times, but it's not necessarily easy to put that info to good use
<clever> and it doesnt toposort the queue, so it may build derivation A under B, because B depended on A
<clever> and then the logs for the A job dont say anything
<clever> build steps is just missing: https://hydra.iohk.io/build/217771
<niksnut> I think that can only happen if the build with derivation A at top-level hasn't been loaded from the queue yet

<clever> in the example above, the same job, within a different jobset (a pr build) had built it already, so a toposort wouldnt have actually helped

<manveru> when was the deadline for 18.09?
<manveru> should probably make 2.5 the default ruby for it

<samueldr> manveru: what's left?
<samueldr> or, what needs to be done?
orivej has quit [Ping timeout: 272 seconds]
<manveru> samueldr: just running nix-review
<manveru> not sure what might break, but it should in theory be fine :)
<samueldr> wrt 2.6; with annual ruby releases, on december 25th, the next release will always be around the corner for xx.09 :)
<manveru> yeah
<manveru> but that's alright for 19.03 then
<manveru> there's no rvm patchset for 2.6 yet anyway
<manveru> i thought about packaging the preview-2 branch... would be nice to have those in nixpkgs too
<manveru> but the way it's coupled with railsexpress atm makes it hard

<gchristensen> I just had a nix derivation realize in to the totally wrong thing
<gchristensen> https://gist.github.com/grahamc/a2810119d95dc70368b01183db5212d1 anyone seen this before? a nix-build of pkgs.writeScript produced an empty result
<gchristensen> many times, actually
<gchristensen> niksnut: can you take a look? very mysterious, seems very bad that pkgs.writeScript can fail-and-succeed
<gchristensen> maybe you have ideas on data I can provide
<LnL> hrm
<gchristensen> man, I had hundreds of derivation builds become empty
<LnL> is this only with check mode?
<gchristensen> no, nix-build produced them the first time empty and --check is showing the second time, it is creating them properly
<clever> gchristensen: can you nix-build with -vvvv ?
<LnL> could you make a fully reproducible expression
<gchristensen> that is a problem, I can't
<gchristensen> when I build them again, they are properly created.
<cransom> have a transient failure with a disk full or something silly like that?
<gchristensen> brand new machine, several tb free
<manveru> ok, nix-review just ate all my harddisk
<niksnut> gchristensen: did you have a system crash or something?
<niksnut> and what does nix-store --verify-path say?
<gchristensen> no, nothing crashed and dmesg doesn't say anything
<gchristensen> :/ seems I cant verify the path anymore... I thought I left a few to work with but accidentally fixed them all
<Dezgeg> IIRC domenkozar had reported something similar in the past (unresolved)

<aszlig> domenkozar: hm, just added a PR for nix to use 64bit integers... it's a very very small thing, but if you get nothing else, maybe include it?
