3511e328ec feat(tvix/eval): Implement builtins.readFileType
builtins.readFileType was added to Nix back in version 2.14.

The tests were also moved out of notyetpassing in addition to the
readDir fixtures they depend on.

I caught a bug where we previously used std::fs::metadata (via the
.metadata() method on File) which follows symlinks so it would always
return false for is_symlink(). Instead we now use
std::fs::symlink_metadata directly which does not follow symlinks, so
tests now pass. This wasn't an issue for builtins.readDir as it uses
walkdir and walkdir doesn't follow symlinks either.

549e86d95b feat(tvix/verify-lang-tests): Test nixVersions.nix_{2_3,2_23}
With this change the latest Nix version being checked is 2.23
(previously was 2.18). A warning will now be printed when the
latest verified Nix version is out of date.

I added a test to the skip-list because the behavior of
builtins.dirOf has changed in Nix 2.22

d1b7e08726 fix(tvix/eval): don't force lambda arg in map, mapAttrs & genList
It is pretty pointless to force the function argument if we are going to
use a suspended call later since forcing the function may fail in ways
that are not covered by Catchables (non-recoverable errors, infinite
recursions). From this, it kind of seems as if using #[catch] is never
correct and should be replaced by #[lazy]. Also we should probably try
to come up with more test cases for stuff where laziness gets us out of
the jam as an equivalent to the catchable tests for nonrecoverable
errors.

Fixes b/386.

7b1632ec71 feat(tvix/eval): strengthen significantly catchable test suite
Adds a bunch (notably certain overlapping) tests for catchable situations.

This should cover many scenarios, argument is catchable, element in argument is catchable, function returns
catchable in the middle of the processing, etc.

9256621009 fix(tvix/eval): update identifier quoting to match cppnix 2.17
In cppnix 2.17, commit b72bc4a972fe568744d98b89d63adcd504cb586c, the
libexpr pretty-printing routine was fixed so that it would no longer
pretty-print attrsets with keywords in their attrnames incorrectly.

This commit implements the corresponding fix for tvix, fixes our
tests to work with cppnix>=2.17 oracles, and expands our test cases
to cover all the keywords.

110328232d chore(3p/sources): bump channels & overlays (2023-08-21)
Included changes:

* tvix/eval: enable some lang tests on nix_latest

  Nix 2.16 contains some breaking language changes which Tvix does
  not yet implement, but the existing tests for them are now passed by
  Nix 2.16 (but not yet by Tvix).

* tvix/eval: disable a lang test on nix_latest

  In Nix 2.17, the identifier formatting test fails because some
  behaviour changed. We have not investigated further yet.

* 3p/overlays: use version of ihp-hsx that works with GHC 9.4

  Originally from the separate cl/9185.

* top-level: introduce a mechanism to exclude build targets from CI in
  the top level. This fixes b/296.

* users/grfn: disable builds of xanthous (and dependents) until the
  CLs fixing its build are submitted

* 3p/overlays: build nixos-option against Nix 2.15, the only version
  with which it builds

* 3p/overlays: bump tdlib to 1.8.16

Adds new tests for foldl', intersectAttrs as well as fills in missing

New test cases we don't pass:

- fromTOML timestamp capabilities
- path antiquotation
- replaceStrings is lazier on C++ Nix master

0f71d8f813 test(tvix/eval): genericClosure (pointer) comparison support
genericClosure has very limited support for pointer equality: It relies
on comparison (not equality!) in C++ Nix, so as soon as C++ Nix supports
comparing lists (langVersion >= 6) we can rely on pointer equality for
key.

Since Tvix uses equality, not comparison for the insert, our behavior is
currently different, as documented by the notyetpassing tests.

0005737f11 fix(tvix/eval): make tvix display values like nix-instantiate(1)
In order for the test suite we have currently to be comparable to C++
Nix, we need to display values in the same way. This was largely the
case except in some weird cases.

* <CODE> for thunks and <CYCLE> for repeated thunks (?) are already in
  use. <CODE> formatting is tested by the oracle test suite already.

* Instead of lambda, we need to use <LAMBDA>

* <<primop>> and <<primop-app>> (a formatting C++ Nix uses nowhere)
  now are <PRIMOP> and <PRIMOP-APP>.

We'll probably want to have a fancier display of values (in a separate
trait) down the line. This could be used for interactive usage, e.g. the
REPL or a potential debugger.

There is a peculiarity with C++ Nix 2.3 formatting primops: import is
considered a <<PRIMOP-APP>>, since it is internally implemented by means
of scopedImport. This implementation detail no longer leaks in C++ Nix
2.13 nor in Tvix.

<CYCLE> display is untested at the moment, since we exhibit a
discrepancy to C++ Nix 2.3. Our current detection is more similar to C++
Nix 2.13—luckily it is also the more consistent of the two. See also
b/245.

d0a836b0e1 feat(tvix/eval): Implement comparison for lists
Lists are compared lexicographically in C++ nix as of [0], and our
updated nix test suites depend on this. This implements comparison of
list values in `Value::nix_cmp` using a very similar algorithm to what
C++ does - similarly to there, this requires passing in the VM so we can
force thunks in the list elements as we go.

b410655a5e test(tvix/verify-lang-tests): also check notyetpassing tests
Adding these to the C++ Nix CI ensures that it is possible for the
tests in that directory to pass at all. Mainly this would catch
situations like fixed in a previous CL when moving the tests around
would break them so that they wouldn't even pass in C++ Nix.

For this to work, we need to track skips by basename to be
directory-independent (assuming that every skipped test name is unique
is hopefully okay).

8e188d6235 test(tvix/eval): update C++ Nix test suite to current master
The language test suite actually doesn't require flakes and the
new features are mostly sensible (added builtins) as well as some
tests for regressions the C++ implementation experienced.

The path interpolation test is not included in this update because there
is no way to construct an location-independent .exp file for it (the C++
repo also doesn't have one). We may still want to implement that feature
eventually (in case rnix adds support for it).

The C++ Nix revision used is ac0fb38e8a5a25a84fa17704bd31b453211263eb.

292a751388 test(tvix): nix-planned test verification using C++ Nix 2.3 and 2.11
Reimplement the test discovery of the lang tests script in Nix which
allows for a more flexible skipping logic that can e.g. react to the C++
Nix version used. This allows us to run the test suite against both
C++ Nix 2.3 and the latest C++ Nix version 2.11. The latter is mainly
useful, so we can implement newer Nix features and still verify them
against the C++ implementation.
