2019-10-21nix make-content-addressable: Add examplesEelco Dolstra
2019-10-21Fix buildEelco Dolstra
2019-10-21Allow content-addressable paths to have referencesEelco Dolstra
This adds a command 'nix make-content-addressable' that rewrites the specified store paths into content-addressable paths. The advantage of such paths is that 1) they can be imported without signatures; 2) they can enable deduplication in cases where derivation changes do not cause output changes (apart from store path hashes). For example, $ nix make-content-addressable -r nixpkgs.cowsay rewrote '/nix/store/g1g31ah55xdia1jdqabv1imf6mcw0nb1-glibc-2.25-49' to '/nix/store/48jfj7bg78a8n4f2nhg269rgw1936vj4-glibc-2.25-49' ... rewrote '/nix/store/qbi6rzpk0bxjw8lw6azn2mc7ynnn455q-cowsay-3.03+dfsg1-16' to '/nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16' We can then copy the resulting closure to another store without signatures: $ nix copy --trusted-public-keys '' ---to ~/my-nix /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 In order to support self-references in content-addressable paths, these paths are hashed "modulo" self-references, meaning that self-references are zeroed out during hashing. Somewhat annoyingly, this means that the NAR hash stored in the Nix database is no longer necessarily equal to the output of "nix hash-path"; for content-addressable paths, you need to pass the --modulo flag: $ nix path-info --json /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 | jq -r .[].narHash sha256:0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 1ggznh07khq0hz6id09pqws3a8q9pn03ya3c03nwck1kwq8rclzs $ nix hash-path --type sha256 --base32 /nix/store/iq6g2x4q62xp7y7493bibx0qn5w7xz67-cowsay-3.03+dfsg1-16 --modulo iq6g2x4q62xp7y7493bibx0qn5w7xz67 0ri611gdilz2c9rsibqhsipbfs9vwcqvs811a52i2bnkhv7w9mgw
2019-10-21Add experimental-features settingEelco Dolstra
Experimental features are now opt-in. There is currently one experimental feature: "nix-command" (which enables the "nix" command. This will allow us to merge experimental features more quickly, without committing to supporting them indefinitely. Typical usage: $ nix build --experimental-features 'nix-command flakes' nixpkgs#hello (cherry picked from commit 8e478c234100cf03ea1b777d4bd42a9be7be9e8c, without the "flakes" feature)

700 is pointless since the store is world-readable anyway. And per-user/root/channels must be world-readable.

'nix-daemon' now creates subdirectories for users when they first connect. Fixes #509 (CVE-2019-17365). Should also fix #3127.

Make nix-daemon.plist less fragile on macOS
2019-10-09Make nix-daemon.plist less fragile on macOSDan Callahan
We're calling `wait4path` on the full, resolved `@bindir@/nix-daemon` path. That means we're hardcoding something like: /bin/wait4path /nix/store/zs9c5xhp3zv9p23qnjxp87nl5injsi1i-nix-2.3/bin/nix-daemon && /nix/var/nix/profiles/default/bin/nix-daemon That seems unnecessarily fragile. It might be better to wait4path on the path we intend to call.

Don’t source bashrc in pure mode
2019-10-08Handle empty sandbox_shellMatthew Bauer
Previously, SANDBOX_SHELL was set to empty when unavailable. This caused issues when actually generating the sandbox. Instead, just set SANDBOX_SHELL when --with-sandbox-shell= is non-empty. Alternative implementation to https://github.com/NixOS/nix/pull/3038.
2019-10-08Don’t source bashrc in pure modeMatthew Bauer
Pure mode should not try to source the user’s bashrc file. These may have many impurities that the user does not expect to get into their shell. Fixes #3090
2019-10-08Make preexisting Nix install a warning, not a failureMatthew Bauer
In the multi-user install script, we originally made sure no previous references to Nix existed. This prevented any previous installs from contaminating the new install. However, some users need the ability to repair their existing Nix installation without uninstalling all references to Nix. This change allows users with existing Nix installations to use the installer, while still outputing a warning message on the dangers of this. As a result, the multi-user install script work much more like the single-user install script has worked in the past. This is a requirement for macOS Catalina users now that /Library/LaunchDaemons/org.nixos.nix-daemon.plisg is not managed by the Nix store. If there is ever a change to the .plist, all users will need to rerun this install script to get the new changes. Otherwise, changes to the launch daemon will require manual interventions.
2019-10-08Copy instead of linking launch agentMatthew Bauer
On Catalina, the /nix filesystem might not be mounted at start time. To avoid this service not starting, we need to keep the launch agent outside of the Nix store. A wait4pid will hold for our /nix dir to be mounted. Fixes #3125.
