Useful when we're using a daemon with a chroot store, e.g.
$ NIX_DAEMON_SOCKET_PATH=/tmp/chroot/nix/var/nix/daemon-socket/socket nix-daemon --store /tmp/chroot
Then the client can now connect with
$ nix build --store unix:///tmp/chroot/nix/var/nix/daemon-socket/socket?root=/tmp/chroot nixpkgs#hello
That doesn’t really make sense with CA derivations (and wasn’t even
really correct before because of FO derivations, though that probably
didn’t matter much in practice)
Make ca-derivations require a `ca-derivations` machine feature, and
ca-aware builders expose it.
That way, a network of builders can mix ca-aware and non-ca-aware
machines, and the scheduler will send them in the right place.
When adding a path to the local store (via `LocalStore::addToStore`),
ensure that the `ca` field of the provided `ValidPathInfo` does indeed
correspond to the content of the path.
Otherwise any untrusted user (or any binary cache) can add arbitrary
content-addressed paths to the store (as content-addressed paths don’t
need a signature).
Linux is (as far as I know) the only mainstream operating system that
requires linking with libdl for dlopen. On BSD, libdl doesn't exist,
so on non-FreeBSD BSDs linking will currently fail. On macOS, it's
apparently just a symlink to libSystem (macOS libc), presumably
present for compatibility with things that assume Linux.
So the right thing to do here is to only add -ldl on Linux, not to add
it for everything that isn't FreeBSD.
Only considers the closure in term of `Realisation`, ignores all the
opaque inputs.
Dunno whether that’s the nicest solution, need to think it through a bit
Align all the worker protocol with `buildDerivation` which inlines the
realisations as one opaque json blob.
That way we don’t have to bother changing the remote store protocol
when the definition of `Realisation` changes, as long as we keep the
json backwards-compatible

Move the `closure` logic of `computeFSClosure` to its own (templated) function.
This doesn’t bring much by itself (except for the ability to properly
test the “closure” functionality independently from the rest), but it
allows reusing it (in particular for the realisations which will require
a very similar closure computation)
For whatever reason, many programs trying to access SystemVersion.plist
also open SystemVersionCompat.plist; this includes Python code and
coreutils’ `cat(1)` (but not the native macOS `/bin/cat`). Illustratory
`dtruss(1m)` output:
open("/System/Library/CoreServices/SystemVersion.plist\0", 0x0, 0x0) = 3 0
open("/System/Library/CoreServices/SystemVersionCompat.plist\0", 0x0, 0x0) = 4 0
I assume this is a Big Sur change relating to the 10.16.x/11.x
version compatibility divide and that it’s something along the lines of
a hook inside libSystem.
Fixes a lot of sandboxed package builds under Big Sur.
When we don’t have enough free job slots to run a goal, we put it in
the waitForBuildSlot list & unlock its output locks. This will
continue from where we left off (tryLocalBuild). However, we need the
locks to get reacquired when/if the goal ever restarts. So, we need to
send it back through tryToBuild to get reqacquire those locks.
I think this bug was introduced in
https://github.com/NixOS/nix/pull/4570. It leads to some builds
starting without proper locks.
