2019-05-15Merge remote-tracking branch 'origin/master' into flakesEelco Dolstra
2019-05-15nix: Add --print-build-logs flagEelco Dolstra
This causes 'nix' to print build log output to stderr rather than showing the last log line in the progress bar. Log lines are prefixed by the name of the derivation (minus the version string), e.g. binutils> make[1]: Leaving directory '/build/binutils-2.31.1' binutils-wrapper> unpacking sources binutils-wrapper> patching sources ... binutils-wrapper> Using dynamic linker: '/nix/store/kr51dlsj9v5cr4n8700jliyz8v5b2q7q-bootstrap-stage0-glibc/lib/ld-linux-x86-64.so.2' bootstrap-stage2-gcc-wrapper> unpacking sources ... linux-headers> unpacking sources linux-headers> unpacking source archive /nix/store/8javli69jhj3bkql2c35gsj5vl91p382-linux-4.19.16.tar.xz

2019-02-12nix: Enable pure mode by defaultEelco Dolstra
We want to encourage a brave new world of hermetic evaluation for source-level reproducibility, so flakes should not poke around in the filesystem outside of their explicit dependencies. Note that the default installation source remains impure in that it can refer to mutable flakes, so "nix build nixpkgs.hello" still works (and fetches the latest nixpkgs, unless it has been pinned by the user). A problem with pure evaluation is that builtins.currentSystem is unavailable. For the moment, I've hard-coded "x86_64-linux" in the nixpkgs flake. Eventually, "system" should be a flake function argument.
2019-02-11Move Command and MultiCommand to libutilEelco Dolstra
2019-02-11MultiCommand: Simplify constructionEelco Dolstra
2018-10-26Merge all nix-* binaries into nixEelco Dolstra
These are all symlinks to 'nix' now, reducing the installed size by about ~1.7 MiB.
2018-08-30nix: Remove the -h flagEelco Dolstra
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.
2018-02-08Add 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.
2018-01-31Add 'nix upgrade-nix' commandEelco Dolstra
This command upgrades Nix to the latest stable version by installing a store path obtained from https://github.com/NixOS/nixpkgs/raw/master/nixos/modules/installer/tools/nix-fallback-paths.nix which is the same store path that the installer at https://nixos.org/nix/install.sh uses. The upgrade fails if Nix is not installed in a profile (e.g. on NixOS, or when installed outside of the Nix store).
2017-11-14Make config options available to legacy commandsEelco Dolstra
2017-10-24nix: Respect -I, --arg, --argstrEelco Dolstra
Also, random cleanup to argument handling.
2017-08-29nix edit / log: Operate on a single InstallableEelco Dolstra
2017-08-29nix run: Flush the progress bar before starting the commandEelco Dolstra
2017-08-29nix run: Fix chroot executionEelco Dolstra
Running "nix run" with a diverted store, e.g. $ nix run --store local?root=/tmp/nix nixpkgs.hello stopped working when Nix became multithreaded, because unshare(CLONE_NEWUSER) doesn't work in multithreaded processes. The obvious solution is to terminate all other threads first, but 1) there is no way to terminate Boehm GC marker threads; and 2) it appears that the kernel has a race where unshare(CLONE_NEWUSER) will still fail for some indeterminate amount of time after joining other threads. So instead, "nix run" will now exec() a single-threaded helper ("nix __run_in_chroot") that performs the actual unshare()/chroot()/exec().

2017-07-14nix: Show help when no arguments are givenEelco Dolstra
Fixes #1464.
2017-06-07Don't show flags from config settings in "nix --help"Eelco Dolstra
2017-06-07nix: Add --help-config flagEelco 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
2017-05-16Improve progress indicatorEelco 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.
2017-04-08Process nix.conf options in "new" nix commands, add test.Will Dietz
Without this (minor) change, the options set using "--option" or read from nix.conf were parsed but not used.
2016-04-25nix: Disable verbose buildsEelco Dolstra
2016-04-25Improved logging abstractionEelco Dolstra
This also gets rid of --log-type, since the nested log type isn't useful in a multi-threaded situation, and nobody cares about the "pretty" log type.
