Hi, A few days ago, I've finally re-enabled generation of binary patches for the Nixpkgs channel (the "official" one at http://nixos.org/releases/nixpkgs/channels/nixpkgs-unstable, not the Hydra Nixpkgs jobset). If you now upgrade a package, you may notice that Nix will download binary patches instead of full binaries, depending on what you have in your Nix store. For instance, an upgrade from Firefox 3.6.4 to 3.6.6 is just a 9 KiB download.
BTW, if you have a fast connection then binary patching may actually be slower than downloading the full binary. We should probably take into account CPU and network performance... -- Eelco Dolstra | http://www.st.ewi.tudelft.nl/~dolstra/ _______________________________________________ nix-dev mailing list [email protected] https://mail.cs.uu.nl/mailman/listinfo/nix-dev
