Crucially this introduces BoehmGCStackAllocator, but it also
adds a bunch of wiring to avoid making libutil depend on bdw-gc.
Part of the solutions for #4178, #4200
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.
This makes it even clearer which of the two hashes was specified in the
nix files. Some may think that "wanted" and "got" is obvious, but:
"got" could mean "got in nix file" and "wanted" could mean "want to see in nix file".
Although the non-resolved derivation will never get a cache-hit (it
doesn't have an output path to query the cache for anyways), we might
get one on the resolved derivation.
This makes it possible to have per-project configuration in flake.nix,
e.g. binary caches and other stuff:
nixConfig.bash-prompt-suffix = "[1;35mngi# [0m";
nixConfig.substituters = [ "https://cache.ngi0.nixos.org/" ];
This reverts commit 189e6f5e1d.
After some discussion, it seems better not to bump the major version
number since most of the new features since 2.3 are marked
experimental.
This is primarily useful if you're hacking simultaneously on a package
and one of its dependencies. E.g. if you're hacking on Hydra and Nix,
you would start a dev shell for Nix, and then a dev shell for Hydra as
follows:
$ nix develop \
--redirect .#hydraJobs.build.x86_64-linux.nix ~/Dev/nix/outputs/out \
--redirect .#hydraJobs.build.x86_64-linux.nix.dev ~/Dev/nix/outputs/dev
(This assumes hydraJobs.build.x86_64-linux has a passthru.nix
attribute. You can also use a store path.)
This causes all references in the environment to those store paths to
be rewritten to ~/Dev/nix/outputs/{out,dev}. Note: unfortunately, you
may need to set LD_LIBRARY_PATH=~/Dev/nix/outputs/out/lib because
Nixpkgs' ld-wrapper only adds -rpath entries for -L flags that point
to the Nix store.
NIX_PROFILES is space separated list of directories, and passing it into
for as is is considered to be 1-element list with the whole string. With
shwordsplit option Zsh emulates other shells in this regard ans
implicitely splits unquoted strings into words.
Fixes#4167.
Fix#3975: Currently if Ctrl-C is pressed during a phase, the interactive subshell
is not exited. Removing --rcfile when --phase is present makes bash
non-interactive
Env vars for ZSH were moved from /etc/zshrc to /etc/zshenv in #3608
to address an issue with zshrc getting clobbered by OS updates, but
/etc/zshenv doesn't exist by default--so *nothing* would get set up
for zsh users unless they already happened to have /etc/zshenv.
Creating these files if they don't exist. Also cut separate creation
of profile.d/nix.sh, which isn't needed now.
Some of the changes in #3788 to support non-systemd Nix installs
don't appear to be aware that the darwin installer exists, which
resulted in some skipped steps and inappropriate instructions.
The move from release.nix to flake.nix appears to have lost some
changes from #3628 / 1c56f18a8122b605c28000e295d5e223f272cccd, leaving
create-darwin-volume.sh out of the release tarball.
Under the assumption that this was just an accident/byproduct of when
flake.nix split off and not intentional, I am restoring those edits.
