Due to [nix#6579] the heuristic which allowed us to determine if a
symlink points to a directory is not reliable – if restrict-eval is
enabled it _will_ return wrong results. Until upstream resolves
this (and we backport the patch) it is probably best to not expose this
functionality at all.

This is broken for (as of yet unclear reasons) with restricted
evaluation mode.

When preparing cl/4381 I noticed that we actually handle this case
properly. depot.nix.utils.storePathName depot.path now works as
expected.

In order to make readTree import symlinked directories I've been looking
into how to detect if a symlink points to a directory (since this would
allow us to use symlinks for //nix/sparseTree). I've found a hack for
this:
symlinkPointsToDir = path: isSymlink path &&
builtins.pathExists (toString path + "/.")
Unfortunately it doesn't seem to be possible to distinguish whether the
symlink target does not exist or is a regular file.
Since it's possible, I thought might as well add this to
`pathType`. To make returning the extra information workable, I've
elected to use the attribute set layout used by `//nix/tag`. This
doesn't require us to depend anything (as opposed to yants), but gives
us pattern matching (via `nix.tag.match`) and also quite idiomatic
checking of pathTypes:
pathType ./foo ? file
(pathType ./foo).symlink or null == "symlink-directory"
Nonexistent paths are encoded like this:
pathType ./foo ? missing
Of course we can't use this in readTree (since it must be zero
dependency), but we can easily inline this hack at some point.
