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.
As mentioned in previous commit, Big Sur changes the syntax for the
xpath command slightly.
In the process of testing out replacements for these, I noticed a few
small simplification wins.
- xpath -> xmllint: xpath's cli interface changed in Big Sur
rather than add conditional logic for picking the correct
syntax for xpath, I'm changing to xmllint --xpath, which
appears to be consistent across versions I've tested...
- /plist/dict/key[text()='Writable']/following-sibling::true[1]
doesn't do quite what's expected. It was written to try to
select a <true /> node paired with the Writable key, but it
will also select the *next* <true /> node that appears even
if it was paired with another key.
- I think there's also a logic bug in the conditionals here.
I'm not sure anyone ever actuall saw it, thanks to the xpath
bug, though. With the xpath fix, this conditional passes if /nix
does not exist, / IS writable, and the version is Catalina+.
I think it meant to test for /nix does not exist, / is NOT
writable, and the version is Catalina+. I reworked this lightly
to make it a little clearer at the code level.
checks should be relatively fast, but buildStatic depends on a lot of
stuff that isn't in the binary cache (e.g. musl builds of Git and
Mercurial that we probably don't need since we don't link against
them...).
Having vm-test-run-unnamed for all the test derivation doesn't look very
nice, so in order to better distinguish them from their store path,
let's actually give them proper names.

Perl-based tests are deprecated since NixOS 20.03 and subsequently got
removed in NixOS 20.09, which effectively means that tests are going to
fail as soon as we build it with NixOS 20.09 or anything newer.
I've put "# fmt: off" at the start of every testScript, because
formatting with Black really messes up indentation and I don't think it
really adds anything in value or readability for inlined Python scripts.
