2023-12-11 r/7155 refactor(tvix/*/protos): separate lint targetFlorian Klink3-46/+107
Break up the go-bindings derivation. Keep "protos" containing all proto files (well, and the buf config), and use it for a check phase running linter and formatter, as well as the existing "go-bindings" attribute Change-Id: I52cb9d08570bb76452acb831eb711c5b6c0eacfb Reviewed-on: https://cl.tvl.fyi/c/depot/+/10239 Reviewed-by: raitobezarius <tvl@lahfa.xyz> Autosubmit: flokli <flokli@flokli.de> Tested-by: BuildkiteCI

This function converts from a nix_compat::derivation::Derivation to a BuildRequest. In addition to the Derivation itself, it needs two lookup functions to map input paths to their castore nodes.

2023-12-10 r/7142 fix(tvix/cli): panic on root cause of the fetchurl(non-boot) bugAdam Joseph1-1/+27
Currently we produce wrong drvPaths for a large number of packages that use fetchurl (but not fetchurlBoot, which is what stdenv uses). A simple reproducer is `pkgs.perl538`. I debugged this down to the root cause, which is the fact that tvix doesn't realize that the mapping from FOD-paths to outputHash is *NOT* a 1:1 mapping. It is a many-to-one mapping. You can have lots of different FODs with the same outputHash or even the same outPath. For example, perl538.src and perldevel.src use the same source tarball but a different `version`. Anyways, I have found the root cause but have run out of time for a while, so I've added a panic!() to in the spot where we have a logic bug in order to call it out.

The only thing this was doing was invoking nix-store --add, which is not gonna help us populate the tvix-store at all (and we now have `tvix-store import`). This is also (rightfully) causing clippy warnings, because of some fields being unused. It's more of a skeleton, and rather than shelling out to Nix for some usecases, we might introduce a "compatible" Nix CLI frontend for a subset of commands. Drop this for now, to decrease the noise and confusion.

2023-12-06 r/7120 feat(tvix/eval): rewrite Thunk::force() in nonrecursive formAdam Joseph3-64/+97
This commit rewrites Thunk::force() so that it is not (directly) self-recursive. It maintains a Vec of all the previously-encountered thunks which point to the one it is currently forcing, rather than recursively calling itself. Benefits: - Short term: This commit saves the cost of a round-trip through the generator machinery for the generators::request_force() which is removed by this commit. - Medium term: Once a similar transformation has been applied to nix_cmp(), nix_add(), nix_eq(), and coerce_to_string(), those four functions, along with Thunk::force(), will make non-tail calls only to each other. They can then be merged into a single tail-recursive function which does not use the generator machinery at all: enum Task { Cmp, Add, Eq, CoerceToString, Force}; fn Value::walk(task:Task, v1:Value, v2:Value) { // ... - Long term: The long-term goal here is to use generators **only for builtins** and [Marionette]-style remote control of the VM. In other words: use `async` for things that actually involve concurrency. Calls from the VM to builtins can then be blocking calls, because even cppnix will overflow the stack if you make a MAX_STACK_DEPTH-deep recursive call which passes through a builtin at every stack frame (e.g. `{ func = builtins.sort (a: b: ... func ...) ...}`). This way the inner "tight loop" of the interpreter doesn't pay the costs of `async` and generators. These costs manifest in terms of: performance, complex nonlocal control flow, and language impediments (async Rust is a restricted subset of real Rust, and is missing things like traits).

2023-12-05 r/7119 fix(tvix/eval): Return error rather than panicking on bad substringAspen Smith2-1/+10
If builtins.substring is invoked with (byte!!) offsets that aren't at codepoint boundaries, return an error rather than panicking. This is still incorrect (see b/337) but pushes the incorrectness forward a step.

This fixes a *future* clippy lint: https://rust-lang.github.io/rust-clippy/master/index.html#/incorrect_partial_ord_impl_on_ord_type In essence, because the implementation of *both* Ord and PartialOrd implies that ordering is not partial, all results of PartialOrd should simply be those of Ord. This is to avoid subtle bugs in future refactorings.
