 Mindavi | Does a FOD also need a system parameter? | 05:30:03 |
 @aloisw:kde.org | Yes (even for builtin builders). | 05:36:47 |
 azazel75 | hello guys, I've a flake with both packages and system configurations that use those packages. What happens is that if I change a system configuration, the packages get rebuilt, because the overall source of the flake is changed, but the final contents of the package do not change... is there a way to disconnect this dependency? I've tried with lib.cleanSourceWith, but apparently without success... | 15:06:52 |
 @mewp:nurupo.pl | does the package src include the flake? | 15:07:56 |
| azazel75 | I've tried to avoid it by reimplementing gitignore.gitignoreSourceWith as
gitignoreSourceWith = path:
pkgs.lib.cleanSourceWith {
name = "tinia-src";
filter = gitignoreFilterWith {
basePath = path.origSrc or path;
extraRules = ''
./nix
flake.*
'';
};
src = path;
};
pkgsSrc = gitignoreSourceWith ./.;
| 15:10:55 |
| azazel75 | but I'm not 100% certain that works as I expected... | 15:11:34 |
| @mewp:nurupo.pl | that I don't know. but you can build the package with a builder that will emit the list of source files and check | 15:13:59 |
| @mewp:nurupo.pl | such as find . > $out | 15:14:12 |
| @mewp:nurupo.pl | (there are probably better methods, just none of them come to mind right now) | 15:14:59 |
| azazel75 | thanks, I'll try to do that | 15:15:35 |
| azazel75 | gitIgnoreFilterWith is https://github.com/hercules-ci/gitignore.nix/blob/master/find-files.nix#L24 | 15:16:34 |

| CabalCrow | is there a way to force nixos-rebuild to copy .git folders into the store directory? | 15:48:25 |
| @mewp:nurupo.pl | you could likely create a package with the current configuration repo if that's what you want. no built-in module for that afaik | 15:50:07 |
| azazel75 | so, i did what you suggested mewp , whit a new package like:
pkgsSrcContents = pkgs.stdenvNoCC.mkDerivation {
name = "src-contents";
src = pkgsSrc;
builder = pkgs.writeText "builder.sh" ''
${pkgs.findutils}/bin/find $src >> $out
'';
};
| 15:55:20 |
| CabalCrow | well that is a shame | 15:55:26 |
| azazel75 | it turns out that even if flake.nix isn't in the resulting $src, if I change it between two runs the hash of that $src store path will change | 15:57:12 |
| @mewp:nurupo.pl | interesting, what about this last package containing only the names? does it also change? | 15:58:04 |
| azazel75 | it changes because the path of $src changes... I should calculate a checksum of the whole contents of $src, maybe with a volatile tar command.. | 15:59:35 |
| @mewp:nurupo.pl | you can avoid that by cding to the directory before find | 16:00:18 |
| azazel75 | yes | 16:00:53 |
| @mewp:nurupo.pl | then you'll be able to see if the list of files changes. you can also do find -type f . | sha1sum to see if the hashes differ | 16:02:10 |
| @mewp:nurupo.pl | it would be very weird for the hash to change without src changing | 16:02:45 |
| @mewp:nurupo.pl | (none of this has anything to do with flakes btw, this would work the same without them) | 16:04:19 |
| azazel75 | find -type f . | sha1sum would expose only a difference in the names of the contents though | 16:08:54 |
