2020-10-29Generalize extra-* settingsEelco Dolstra
This removes the extra-substituters and extra-sandbox-paths settings and instead makes every array setting extensible by setting "extra-<name> = <value>" in the configuration file or passing "--<name> <value>" on the command line.
2020-10-21Add NIX_CONFIG env var for applying nix.conf overridesChristian Kampka
2020-10-06Remove static variable name clashesEelco Dolstra
This was useful for an experiment with building Nix as a single compilation unit. It's not very useful otherwise but also doesn't hurt...
2020-09-22Merge pull request #4038 from maljub01/masterEelco Dolstra
Add a nix.conf option for allowing a symlinked store
2020-09-21Serialize SandboxMode enum to string for JSONCole Helbling
Rather than showing an integer as the default, instead show the boolean referenced in the description. The nix.conf.5 manpage used to show "default: 0", which is unnecessarily opaque and confusing (doesn't 0 mean false, even though the default is true?); now it properly shows that the default is true.

2020-09-21Don't include nlohmann/json.hpp in globals.hhEelco Dolstra
This reduces compilation time by 207s. Issue #4045.
2020-09-21Update the variable name accordinglyMarwan Aljubeh
2020-09-18Add a nix.conf option for allowing a symlinked storeMarwan Aljubeh
2020-09-16Complete the `toJSON` instance for `Setting<T>`regnat
Don't let it just contain the value, but also the other fields of the setting (description, aliases, etc..)
2020-08-20Config: Use nlohmann/jsonEelco Dolstra
2020-07-03Shorten the path to the test rootregnat
Fix a socket length failure on the OSX builders
2020-05-12Show hint how to enable experimental featuresEelco Dolstra
2020-05-04Flag: Use designated initializersEelco Dolstra
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.
2020-03-20sandbox: fix /bin/sh on catalinaDaiderd Jordan
Sadly 10.15 changed /bin/sh to a shim which executes bash, this means it can't be used anymore without also opening up the sandbox to allow bash. Failed to exec /bin/bash as variant for /bin/sh (1: Operation not permitted).
2020-03-20libstore: relax default sandbox-paths on darwinDaiderd Jordan

2019-12-21Disable use-sqlite-wal under WSLBrian McKenna
Before: $ nix-channel --update unpacking channels... warning: SQLite database '/nix/var/nix/db/db.sqlite' is busy (SQLITE_PROTOCOL) warning: SQLite database '/nix/var/nix/db/db.sqlite' is busy (SQLITE_PROTOCOL) warning: SQLite database '/nix/var/nix/db/db.sqlite' is busy (SQLITE_PROTOCOL) warning: SQLite database '/nix/var/nix/db/db.sqlite' is busy (SQLITE_PROTOCOL) warning: SQLite database '/nix/var/nix/db/db.sqlite' is busy (SQLITE_PROTOCOL) After: $ inst/bin/nix-channel --update unpacking channels... created 1 symlinks in user environment I've seen complaints that "sandbox" caused problems under WSL but I'm having no problems. I think recent changes could have fixed the issue.
2019-12-17Add priority setting to storesEelco Dolstra
This allows overriding the priority of substituters, e.g. $ nix-store --store ~/my-nix/ -r /nix/store/df3m4da96d84ljzxx4mygfshm1p0r2n3-geeqie-1.4 \ --substituters 'http://cache.nixos.org?priority=100 daemon?priority=10' Fixes #3264.
2019-12-02Merge remote-tracking branch 'origin/recursive-nix'Eelco Dolstra
2019-11-26Add feature to disable URL literalsEelco Dolstra
E.g. $ nix-build '<nixpkgs>' -A hello --experimental-features no-url-literals error: URL literals are disabled, at /nix/store/vsjamkzh15r3c779q2711az826hqgvzr-nixpkgs-20.03pre194957.bef773ed53f/nixpkgs/pkgs/top-level/all-packages.nix:1236:11 Helps with implementing https://github.com/NixOS/rfcs/pull/45.
2019-11-22getEnv(): Return std::optionalEelco Dolstra
This allows distinguishing between an empty value and no value.
2019-11-06Enable recursive Nix using a featureEelco Dolstra
Derivations that want to use recursion should now set requiredSystemFeatures = [ "recursive-nix" ]; to make the daemon socket appear. Also, Nix should be configured with "experimental-features = recursive-nix".
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)
2018-10-31config: use all of XDG_CONFIG_DIRSLinus Heckemann
Previously, config would only be read from XDG_CONFIG_HOME. This change allows reading config from additional directories, which enables e.g. per-project binary caches or chroot stores with the help of direnv.
2018-09-28Check requiredSystemFeatures for local buildsEelco Dolstra
For example, this prevents a "kvm" build on machines that don't have KVM. Fixes #2012.
2018-05-30Modularize config settingsEelco Dolstra
Allow global config settings to be defined in multiple Config classes. For example, this means that libutil can have settings and evaluator settings can be moved out of libstore. The Config classes are registered in a new GlobalConfig class to which config files etc. are applied. Relevant to https://github.com/NixOS/nix/issues/2009 in that it removes the need for ad hoc handling of useCaseHack, which was the underlying cause of that issue.
2018-04-11initPlugins: Fix dlopen error message.Shea Levy
2018-02-19Merge branch 'register-settings' of https://github.com/shlevy/nixEelco Dolstra
2018-02-15Set backup MANPATH in case man path isn’t set correctly.Matthew Bauer
Previously, this would fail at startup for non-NixOS installs: nix-env --help The fix for this is to just use "nixManDir" as the value for MANPATH when spawning "man". To test this, I’m using the following: $ nix-build release.nix -A build $ MANPATH= ./result/bin/nix-env --help Fixes #1627
2018-02-13Allow plugins to define new settings.Shea Levy
2018-02-13Enable specifying directories in plugin-files.Shea Levy
2018-02-08Add plugins to make Nix more extensible.Shea Levy
All plugins in plugin-files will be dlopened, allowing them to statically construct instances of the various Register* types Nix supports.
2017-11-21Propagate flags like --sandbox to the daemon properlyEelco Dolstra
2017-10-24nix: Respect -I, --arg, --argstrEelco Dolstra
Also, random cleanup to argument handling.
2017-10-24Remove the builder-files optionEelco Dolstra
You can now include files via the "builders" option, using the syntax "@<filename>". Having only one option makes it easier to override builders completely. For backward compatibility, the default is "@/etc/nix/machines", or "@<filename>" for each file name in NIX_REMOTE_SYSTEMS.
2017-07-30Replace Unicode quotes in user-facing strings by ASCIIJörg Thalheim
Relevant RFC: NixOS/rfcs#4 $ ag -l | xargs sed -i -e "/\"/s/’/'/g;/\"/s/‘/'/g"
2017-06-12Provide a builtin default for $NIX_SSL_CERT_FILEEelco Dolstra
This is mostly to ensure that when Nix is started on macOS via a launchd service or sshd (for a remote build), it gets a certificate bundle.
2017-06-07Don't show flags from config settings in "nix --help"Eelco Dolstra
2017-06-07nix: Make all options available as flagsEelco Dolstra
Thus, instead of ‘--option <name> <value>’, you can write ‘--<name> <value>’. So --option http-connections 100 becomes --http-connections 100 Apart from brevity, the difference is that it's not an error to set a non-existent option via --option, but unrecognized arguments are fatal. Boolean options have special treatment: they're mapped to the argument-less flags ‘--<name>’ and ‘--no-<name>’. E.g. --option auto-optimise-store false becomes --no-auto-optimise-store
2017-05-15Add --with-sandbox-shell configure flagEelco Dolstra
And add a 116 KiB ash shell from busybox to the release build. This helps to make sandbox builds work out of the box on non-NixOS systems and with diverted stores.
2017-05-02Replace $NIX_REMOTE_SYSTEMS with an option "builder-files"Eelco Dolstra
Also, to unify with hydra-queue-runner, allow it to be a list of files.
2017-04-20Improve nix show-config --jsonEelco Dolstra
In particular, show descriptions. This could be used for manpage generation etc.
2017-04-20Setting: Remove "Tag" template argumentEelco Dolstra
2017-04-20Read per-user settings from ~/.config/nix/nix.confEelco Dolstra
2017-04-13Convert Settings to the new config systemEelco Dolstra
This makes all config options self-documenting. Unknown or unparseable config settings and --option flags now cause a warning.
2017-04-13Merge branch 'rework-options' of https://github.com/copumpkin/nixEelco Dolstra
2017-03-30Add exec primop behind allow-unsafe-native-code-during-evaluation.Shea Levy
Execute a given program with the (optional) given arguments as the user running the evaluation, parsing stdout as an expression to be evaluated. There are many use cases for nix that would benefit from being able to run arbitrary code during evaluation, including but not limited to: * Automatic git fetching to get a sha256 from a git revision * git rev-parse HEAD * Automatic extraction of information from build specifications from other tools, particularly language-specific package managers like cabal or npm * Secrets decryption (e.g. with nixops) * Private repository fetching Ideally, we would add this functionality in a more principled way to nix, but in the mean time 'builtins.exec' can be used to get these tasks done. The primop is only available when the 'allow-unsafe-native-code-during-evaluation' nix option is true. That flag also enables the 'importNative' primop, which is strictly more powerful but less convenient (since it requires compiling a plugin against the running version of nix).
2017-03-15Store: Add a method for getting build logsEelco Dolstra
This allows various Store implementations to provide different ways to get build logs. For example, BinaryCacheStore can get the build logs from the binary cache. Also, remove the log-servers option since we can use substituters for this.
