2022-09-23 r/4963 feat(tvix/eval): implement 'builtins.filter'Vincent Ambo1-0/+29
This is a little ugly because the plain Iterator::filter method can not be used (it does not support fallible primitives), so we need to resort to an `Iterator::filter_map` and deal with the wrapping in Options everywhere. This prevents use of `?` which introduces the need for some matching, but it's not *too* bad.

2022-09-22 r/4960 fix(tvix/eval): handle thunks in arithmetic builtinssterni1-20/+20
The simplest solution seems to be to pass references to arithmetic_op!() which avoids the moving annoyance we had to deal with in the builtins (no more popping!). We then use .force() to force the values and dereference any Thunks (which arithmetic_op! doesn't do for us).

2022-09-21 r/4950 fix(tvix/eval): compare versions with an extra empty componentsterni2-2/+17
This is necessary because builtins.compareVersions compares versions in a subtly not-quite-but-still-lexicographical way: `pre` for example can have an effect if it is post-fixed: `2.3 < 2.3pre`. This is a violation of the rule that in a lexicographical ordering, the longer string is considered greater if they are otherwise equal. builtins.compareVersion is comparing lexicographically though, if you do the following transformation beforehand: 2.3 --split--> [ "2" "3" ] --append--> [ "2" "3" "" ] 2.3pre --split--> [ "2" "3" "pre" ] --append--> [ "2" "3" "pre" "" ] Comparing the transformed version is then done lexicographically: 2.3 < 2.3.0pre since [ "2" "3" "" ] < [ "2" "3" "0" "pre" ] Here, the `pre` rule never comes into effect because no comparison on it happens, instead we use the longer string rule of a lexicographical comparison. In the C++ codebase, the reason for this behavior is that the iterator-esque construct they use always yields the empty string before it exposes it has been fully consumed. This is probably intentional to support the postfixed `pre` which is, for example, used by NixOS versions (e.g. unstable post 22.05 is 22.11-pre). We replicate this behavior using the `Chain` iterator in `VersionPartsIter::new_for_cmp`.

This is based on the [relevant code] in C++ Nix. Our version has more branches because the C++ one only checks if it is less than or not, so can save handling a few cases. We on the other hand, can avoid calling the algorithm twice. It'd be nice to implement proptests for this in the future and to make sure that this weird little algorithm doesn't violate the Ord laws.

This was fairly easy, thanks to the work already done by Thomas Frank. However, the implementation is suboptimal because we parse number parts only to convert them back to strings afterwards. I've chosen to tackle this problem in the future, since having an (inefficient) implementation of splitVersion will be helpful for debugging the slight discrepancies between C++ Nix and Tvix in the case of compareVersions.

This makes it possible to call a callable value (builtin or closure/lambda) directly, without unwrapping it first. This is needed for pretty much all higher-order functions to work correctly. This is mostly equivalent to the previous code in coerce_to_string for calling `__toString`, except it expects the argument(s) to already be placed on the stack. Note that the span for the `NotCallable` error is not currently guaranteed to make any sense, will experiment with this.

This function is necessary for all builtins that expect some form of path as an argument. It is merely a wrapper around coerce_to_string that can shortcut if we already have a path. The absolute path check is done in the same way as in C++ Nix for compatibility, although it should probably be revised in the long term (think about Windows, for example).

2022-09-08 r/4741 feat(tvix/eval): ensure all errors always carry a spanVincent Ambo1-10/+10
Previously error spans were optional because the information about code spans was not available at runtime. Now that this information has been added, the error type will always carry a span. This change is very invasive all throughout the codebase. This is due to the fact that many functions that are called *by* the VM expected to return `EvalResult`, but this no longer works as the span information is not available to those functions - only to the VM itself. To work around this the majority of these functions have been changed to return `Result<T, ErrorKind>` instead and an accompanying macro in the VM constructs the "real" error. Note that this implementatino currently has a bug where errors occuring within thunks will yield the location at which the thunk was forced, not the location at which the error occured within the code. This will be fixed soon, but the commit is large enough as is.

2022-09-03 r/4605 refactor(tvix/eval): introduce Closure struct in Value typeVincent Ambo1-1/+1
This struct will carry the upvalue machinery in addition to the lambda itself. For now, all lambdas are wrapped in closures (though technically analysis of the environment can later remove innermost Closure wrapper, but this optimisation may not be worth it).
