Clean up daemon handling Split `common.sh` into the vars and functions definitions vs starting the daemon (and possibly other initialization logic). This way, `init.sh` can just `source` the former. Trying to start the daemon before `nix.conf` is written will fail because `nix daemon` requires `--experimental-features 'nix-command'`. `killDaemon` is idempotent, so it's safe to call when no daemon is running. `startDaemon` and `killDaemon` use the PID (which is now exported to subshells) to decide whether there is work to be done, rather than `NIX_REMOTE`, which might conceivably be set differently even if a daemon is running. `startDaemon` and `killDaemon` can save/restore the old `NIX_REMOTE` as `NIX_REMOTE_OLD`. `init.sh` kills daemon before deleting everything (including the daemon socket). 2021-12-09 15:16:18 +00:00			`# Don't start the daemon`

Make init.sh safe to run twice `init.sh` is tested on its own. We used to do that. I deleted it in 4720853129b6866775edd9f90ad6f10701f98a3c but I am not sure why. Better to just restore it; at one point working on this every other test passed, so seems good to check whether `init.sh` can be run twice. We don't need to run `init.sh` twice, but I want to try to make our tests as robust as possible so that manual debugging (where tests for better or worse might be run ways that we didn't expect) is less fragile. 2021-12-09 15:16:18 +00:00			`# We would delete any daemon socket, so let's stop the daemon first.`

Rename a few configuration options In particular, drop the "build-" and "gc-" prefixes which are pointless. So now you can say nix build --no-sandbox instead of nix build --no-build-use-sandbox 2017-08-31 12:28:25 +00:00			`keep-derivations = false`

Set gc-reserved-space to 0 in tests This reduces the amount of disk space needed to run the tests from half a gigabyte to 10 megabytes. 2020-07-02 14:37:30 +00:00			`gc-reserved-space = 0`
Use no substituers by default in the tests Otherwise https://cache.nixos.org is chosen by default, causing the OSX testsuite to hang inside the sandbox. (In a way, this is probably rugging an actual bug under the carpet as Nix should be able to gracefully timeout in such a case, but that's beyond mac OSX-fu) 2020-12-09 13:53:45 +00:00			`substituters =`

Allow running all the tests with the daemon When `NIX_DAEMON_PACKAGE` is set, make all the tests use the Nix daemon. That way we can test every piece of Nix functionality both with and without the daemon.
