@lisanna-dettwyler:matrix.orgLisannabut feel free to comment on the unmerged ones in case there's anything applicable before I get them accepted and port them to Lix23:15:57

@lisanna-dettwyler:matrix.orgLisannaGetting used to gerrit again, I'm working on porting https://github.com/NixOS/nix/pull/15105. That PR has two commits, one for the build hook signals and one for the progress bar shutdown message. Should I open these as different changes?13:31:30
@raitobezarius:matrix.orgraitobezariusYes, but be aware that Lix codebase is quite different in some areas (notably interruptions wise) from cppNix13:56:30

@blokyk:matrix.orgzoë (she/her) this is probably very dumb but: I'm trying to follow "Getting Started with Gerrit", and since it specifically points out "Now you can just git commit your change. No need to create a separate branch", i committed on main directly, but then the no-commit-on-branch commit hook failed because i tried to commit to main, so... am i missing something? 03:11:46
@lisanna-dettwyler:matrix.orgLisannaIt's still probably a good idea to separate your changes into their own branches, otherwise you'll have to rebase just to edit changes that happened before you make another, unrelated change03:16:34
@blokyk:matrix.orgzoë (she/her)right, that makes sense, i was just a little confused at the docs ^^;03:17:23
@blokyk:matrix.orgzoë (she/her)aaaand first CL submitted :D ...it's an 8-bytes diff x)03:24:38

I think that sentence was about remote branches, but you're right it's confusing

I think there were a few CLs on the Gerrit but nothing being actively worked
The other thing that I could do if it helps is test things and try to find bugs. I did do some C++ work in the past, but may lack the time to do it justice here at least for about 30 days or so

@qyriad:katesiria.orgQyriadwe are not in any rush 🙂17:20:53
@samrose:matrix.orgsamroseWould it help to also test out the existing Lix code and try to find issues/bugs etc?17:23:21
@qyriad:katesiria.orgQyriadabsolutely17:23:41
@samrose:matrix.orgsamrose
  • how do people feel about the existing test suite that comes along with nix source code or Lix?
17:23:48
@qyriad:katesiria.orgQyriadit's pitiful17:24:10
@samrose:matrix.orgsamroseheh 17:24:16
@raitobezarius:matrix.orgraitobezariusexpanding it is cool17:24:23
@raitobezarius:matrix.orgraitobezariuswriting new tests for builtins which are not tested17:24:30
@raitobezarius:matrix.orgraitobezariusnew test behaviors, etc.17:24:32
@qyriad:katesiria.orgQyriad we have three flavors of test:
  1. gtest (offer only available in libexpr and libutil)

  2. bash script

  3. virtual machine


the vast, vast majority of testing is in the "bash script" flavor and it is a mess
17:25:01
@samrose:matrix.orgsamroseI was just going to ask on the "functional" tests: do we still like using bash there?17:25:56
@samrose:matrix.orgsamrosethe last time that I worked on a major nix related cli project that used bash, or bats for testing, over time it became rather kind of hard to maintain17:26:42
@samrose:matrix.orgsamroseI am not usually a big python fan, but in that project we heard from some in the Rust community that they actually use Python to test CLI and seem to have success there. 17:27:59
@qyriad:katesiria.orgQyriadno gods please kill bash testing. the problem is that it's kind of really difficult to migrate an entire test suite and be sure that you actually migrated the test suite correctly and won't lose coverage accidentally in the process, which makes any kind of migration a bit nerve wracking17:28:36
@samrose:matrix.orgsamroseyes it's a rather large undertaking17:28:52
@samrose:matrix.orgsamrosecould be done in chunks17:28:59
