Fairly straightforward, only thing of note is that we coerce (weakly) to string here as well. Change-Id: I03b427e657e402f1f9eb0f795b689bbf5092aba1 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6745 Tested-by: BuildkiteCI Reviewed-by: wpcarro <wpcarro@gmail.com> Reviewed-by: tazjin <tazjin@tvl.su>
2022-09-22 r/4960 fix(tvix/eval): handle thunks in arithmetic builtinssterni10-28/+32
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).

2022-09-22 r/4958 fix(tvix/eval): support string identifiers in inheritsVincent Ambo10-81/+138
This updates rnix-parser to a version where inherits provide an iterator over `ast::Attr` instead of `ast::Ident`, which mirrors the behaviour of Nix (inherits can have (statically known) strings as their identifiers). This actually required some fairly significant code reshuffling in the compiler, as there was an implicit assumption in many places that we would have an `ast::Ident` node available when dealing with variable access (which is then explicitly only not true in this case).

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 is the New Thing that is intended to replace the find-owners and owners plugins. In particular: * It inserts a submit requirement rather than providing a Prolog predicate. * The default OWNERS file formats are suspiciously Googley. * It provides a neat UI for finding OWNERS and tracking approval state on a per-file basis. When we fully migrate to using the code-owners plugin, a few things will need to land, which I will likely do "offline" directly to the Gerrit backing Git repos: * Add the corresponding Gerrit config * Replace OWNERS files depot-wide * Add OWNERS files to the refs/meta/config branch * Introduce the Owners-Override label, settable by depot-interventions The enclosed patch adds two extra pieces of functionality that we need in tvldepot but aren't upstream: 1. The ability to just specify usernames rather than email addresses 2. The ability to specify `group:GROUPNAME`, _as long as_ that group is visible to everyone. This is a restriction intended to avoid having the plugin just leak group membership.

Instead of arity, we pass a array reference to Builtin::new that describes how many arguments there are and which of them need to be forced, eliminating the need to force manually. Note that this change doesn't fix some of the instances where the the Builtin doesn't consider that the value could be a Thunk.

2022-09-19 r/4916 feat(tvix/eval): Support builtins.substringWilliam Carroll4-0/+61
Nix's `builtins.substring`: - doesn't accept negative indexes for `beg` or `end`. Compare the error messages for: - `builtins.substring -3 5 "testing"` - `builtins.substring 3 -5 "testing"` - `builtins.substring -3 -5 "testing"` - returns an empty string when `beg >= end` - allows `end` to exceed the length of the input string Change-Id: I83af7a099d81b6d537ebe5029d946c7031cb7113 Reviewed-on: https://cl.tvl.fyi/c/depot/+/6555 Reviewed-by: wpcarro <wpcarro@gmail.com> Autosubmit: wpcarro <wpcarro@gmail.com> Reviewed-by: tazjin <tazjin@tvl.su> Tested-by: BuildkiteCI

2022-09-18 r/4914 refactor(tvix/eval): Simplify forcing in builtinsGriffin Smith2-97/+90
Refactor the `force!` macro to a method on `Value` which returns a smart-pointer-esque type, which simplifies the callsite and eliminates rightward drift, especially for high-arity builtins.
