Let's use CET, an hour later than the current meeting at least, creating when2meet
- "WET/WEST"? western european time
- did anyone do a perf check?
- @tomberek: been using a container to test lazy-trees
- Read dir might get more information than needed, e.g. modification time, and modification time is in the zip file, something like that
- @infinisil: If lazy trees causes problems then it has bigger problems
- @tomberek:
builtins.readDirdoes a stat call on each entry to figure out if it's a directory/file/symlinks! - https://github.com/NixOS/nix/blob/master/src/libexpr/primops.cc#L1644-L1653
- @infinisil: Can easily optimize in the future
- @tomberek: Only slow the first time, then linux cache
- @tomberek:
readDiris compatible with pure flakes btw - @tomberek: we need some actual numbers to understand the tradeoff
- eg: all-packages.nix LOC: -5% of original, eval time +7%
- @infinisil: start with simplest tooling
- @infinisil: will ping people when starting a mob programming session
- @tomberek Can test performance on various platforms and filesystems, Nix versions etc.
