Cole Helbling 244300c1ad RunCommand: remove unused and problematic imports
Since breaking the filename construction out to a helper function,
Hydra::Model::DB is no longer used. Importing Hydra::Helper::Nix,
however, has the potential to break tests, so just use the functions we
need without importing the entire module.

Cole Helbling fdf6f4d3da RunCommand: use IPC::Run3::run3 instead
run3 just seems to do better handling for what we want to do, and
requires less deep-reaching changes to this plugin to get it to play
nice, as IPC::Run::run would.

Cole Helbling bb16f4fb10 RunCommand: set umask when creating log paths
This uses the somewhat restrictive umask of 0027 so that people outside
the user or group cannot read the files. This also helps to inhibit
TOCTOU where someone else has a handle to our file before we chmod it
and after we close it.

Graham Christensen 7e9e82398d build-remote: copy missing paths from the binary cache to localhost
In a Hydra instance I saw:

    possibly transient failure building ‘/nix/store/X.drv’ on ‘localhost’:
      dependency '/nix/store/Y' of '/nix/store/Y.drv' does not exist,
      and substitution is disabled

This is confusing because the Hydra in question does have substitution enabled.

This instance uses:

  keep-outputs = true
  keep-derivations = true

and an S3 binary cache which is not configured as a substituter in the nix.conf.

It appears this instance encountered a situation where store path Y was built
and present in the binary cache, and Y.drv was GC rooted on the instance,
however Y was not on the host.

When Hydra would try to build this path locally, it would look in the binary
cache to see if it was cached:

    (nix)
    439      bool valid = isValidPathUncached(storePath);
    440
    441      if (diskCache && !valid)
    442          // FIXME: handle valid = true case.
    443          diskCache->upsertNarInfo(getUri(), hashPart, 0);
    444
    445      return valid;

Since it was cached, the store path was considered Valid.

The queue monitor would then not put this input in for substitution, because
the path is valid:

    (hydra)
    470          if (!destStore->isValidPath(*i.second.path(*localStore, step->drv->name, i.first))) {
    471              valid = false;
    472              missing.insert_or_assign(i.first, i.second);
    473          }

Hydra appears to correctly handle the case of missing paths that need
to be substituted from the binary cache already, but since most
Hydra instances use `keep-outputs` *and* all paths in the binary cache
originate from that machine, it is not common for a path to be cached
and not GC rooted locally.

I'll run Hydra with this patch for a while and see if we run in to the
problem again.

A big thanks to John Ericson who helped debug this particular issue.

Fixes yath output. It used to say:

Now it says:

I'm not sure this is a good implementation as-is. It does work,
but the password gets echo'd to the screen. I tried to use IO::Prompt
but IO::Prompt really seems to want to read the password from ARGV.
