2020-08-06Add hashed-mirrors backMatthew Bauer
Some users have their own hashed-mirrors setup, that is used to mirror things in addition to what’s available on tarballs.nixos.org. Although this should be feasable to do with a Binary Cache, it’s not always easy, since you have to remember what "name" each of the tarballs has. Continuing to support hashed-mirrors is cheap, so it’s best to leave support in Nix. Note that NIX_HASHED_MIRRORS is also supported in Nixpkgs through fetchurl.nix. Note that this excludes tarballs.nixos.org from the default, as in \#3689. All of these are available on cache.nixos.org.

Unless I am misinformed, using the `nixpkgs` repository directly is now preferred?

General cleanup that makes it easier to search for the term.
2020-04-14add NIX_USER_CONF_FILESzimbatm
Motivation: maintain project-level configuration files. Document the whole situation a bit better so that it corresponds to the implementation, and add NIX_USER_CONF_FILES that allows overriding which user files Nix will load during startup.
2020-03-23doc: Files in the store have modes 444/555, not 644/755Greg Price
This line has been this way since it was written, in 9e08f5efe in 2006. I think it was just a small mistake then; Eelco's thesis earlier that year says the permission on each file is set to 0444 or 0555 in a derivation's output as part of the build process. In any case I'm pretty sure that's the behavior now.
2020-03-19Remove the --delete option for --gcjakobrs
Running `nix-store --gc --delete` will, as of Nix 2.3.3, simply fail because the --delete option conflicts with the --delete operation. $ nix-store --gc --delete error: only one operation may be specified Try 'nix-store --help' for more information. Furthermore, it has been broken since at least Nix 0.16 (which was released sometime in 2010), which means that any scripts which depend on it should have been broken at least nine years ago. This commit simply formally removes the option. There should be no actual difference in behaviour as far as the user is concerned: it errors with the exact same error message. The manual has been edited to remove any references to the (now gone) --delete option. Other information: * Path for Nix 0.16 used: /nix/store/rp3sgmskn0p0pj1ia2qwd5al6f6pinz4-nix-0.16

Make curl's low speed limit configurable via stalled-download-timeout. Before, this limit was five minutes without receiving a single byte. This is much too long as if the remote end may not have even acknowledged the HTTP request.

2019-08-02Add a post-build-hookregnat
Passing `--post-build-hook /foo/bar` to a nix-* command will cause `/foo/bar` to be executed after each build with the following environment variables set: DRV_PATH=/nix/store/drv-that-has-been-built.drv OUT_PATHS=/nix/store/...build /nix/store/...build-bin /nix/store/...build-dev This can be useful in particular to upload all the builded artifacts to the cache (including the ones that don't appear in the runtime closure of the final derivation or are built because of IFD). This new feature prints the stderr/stdout output to the `nix-build` and `nix build` client, and the output is printed in a Nix 2 compatible format: [nix]$ ./inst/bin/nix-build ./test.nix these derivations will be built: /nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv building '/nix/store/ishzj9ni17xq4hgrjvlyjkfvm00b0ch9-my-example-derivation.drv'... hello! bye! running post-build-hook '/home/grahamc/projects/github.com/NixOS/nix/post-hook.sh'... post-build-hook: + sleep 1 post-build-hook: + echo 'Signing paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Signing paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + echo 'Uploading paths' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: Uploading paths /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation post-build-hook: + sleep 1 post-build-hook: + printf 'very important stuff' /nix/store/qr213vjmibrqwnyp5fw678y7whbkqyny-my-example-derivation [nix-shell:~/projects/github.com/NixOS/nix]$ ./inst/bin/nix build -L -f ./test.nix my-example-derivation> hello! my-example-derivation> bye! my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Signing paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Signing paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + echo 'Uploading paths' /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> Uploading paths /nix/store/c263gzj2kb2609mz8wrbmh53l14wzmfs-my-example-derivation my-example-derivation (post)> + sleep 1 my-example-derivation (post)> + printf 'very important stuff' [1 built, 0.0 MiB DL] Co-authored-by: Graham Christensen <graham@grahamc.com> Co-authored-by: Eelco Dolstra <edolstra@gmail.com>
