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.

Another day, another import from derivation avoided by
builtins.unsafeDiscardStringContext!

This is a wrapper around baseNameOf which also can deal with
derivations. Added to //nix/utils since I've found myself introducing an
ad-hoc implementation of this for both //web/bubblegum and //nix/buildC.

Setting meta.targets to include all derivations in the different package
sets in Profpatsch's user folder makes them checked by CI until they do
the readTree refactor as promised.
To reduce code duplication we handle this in a simple function which is
exposed from nix.utils which may be a good place for depot specific bits
and bops we accumulate over time.
To get around the issue of too nested sets we perform the following
renames:
* users.Profpatsch.tests gets moved into its own directory
* users.Profpatsch.arglib.netencode now lives in its own file instead of
the default.nix
* users.Profpatsch.netstring.tests gets moved into its own directory
