The project is finished and is not recommended for production; just use nscd.
Turbonss duly implements the full user/group API in `src/libnss.zig`: feel free
to copy that.
to copy that. turbonss is only 2-5 times faster than nscd, which usually does
not matter (including for my original use case).
Yours truly (the author) worked on this for about 7 months. And when this was
finished it turned out that just slapping nscd on top of the existing NSS
implementation is almost as fast as this.
implementation is fast enough.
Dependencies
------------
1. zig nightly compiler (0.10 should work when it comes out).
1. zig v0.10. turbonss uses stage1 (the C++ version) and is not compatible with
stage2.
2. [cmph][cmph]: bundled with this repository.

@ -35,3 +35,5 @@ This project uses [git subtrac][git-subtrac] for managing dependencies. They
work just like regular submodules, except all the refs of the submodules are in
this repository. Repeat after me: all the submodules are in this repository.
So if you have a copy of this repo, dependencies will not disappear.
