2023-03-19 r/6028 feat(tvix/store/bin): print store pathFlorian Klink1-0/+38
After ingestion of the contents into the store, this will use the NonCachingNARCalculationService to create a NAR stream or the contents of the path, and use our Derivation output path calculation machinery to determine the output path (using recursive hashing strategy). In a real-world scenario, we obviously want to cache these calculations, but this should be sufficient to tinker around with it.

2023-03-17 r/6027 fix(tvix/eval): use span of `set` for OpForce in attribute accessVincent Ambo1-2/+2
Emits the span of the `set` that is being accessed in the `force` operation of an attribute access. Looking at traces, it's a lot more useful to get information about *what* is being forced, as in cases like `foo.bar` it can be misleading to have an error highlight `bar`, when the error occured while forcing `foo` to be able to access `bar` in the first place.

2023-03-17 r/6026 feat(tvix/eval): report all known spans on infinite recursionVincent Ambo3-16/+80
This reports the span 1. of the code within a thunk, 2. of the place where the thunk was instantiated, 3. of the place where the thunk was first forced, 4. of the place where the thunk was forced again, when yielding an infinite recursion error, which hopefully makes it easier to debug them. The spans are tracked in the ThunkRepr::Blackhole variant when putting a thunk under evaluation. Note that we currently have some loss of span precision in the VM loop when switching between frame types, so spans 3/4 are currently a bit wonky. Working on it.

2023-03-17 r/6025 feat(tvix/eval): track span of first force in a thunk blackholeVincent Ambo5-17/+48
This is step 1 towards being able to use all 4 spans that we know when dealing with infinite recursion. It tracks the span at which the force of a thunk was first requested when constructing a blackhole, so that we can highlight the spans of the first and second forces. These are actually the least relevant spans, but the easiest to put in place, more coming soon.

2023-03-17 r/6024 feat(tvix/eval): add generator "name" to NativeError kindVincent Ambo3-12/+29
This produces traces in which we can see what kind of native code was run. Note that these "names" are named after the generator message, so these aren't *really* intended for end-user consumption, but we can give them saner names later. Example: https://gist.github.com/tazjin/82b24e92ace8e821008954867ee05057 This already makes the traces a little easier to parse.

2023-03-17 r/6023 feat(tvix/eval): enrich errors with VM's frame stack informationVincent Ambo4-129/+242
When emitting an error at runtime, the VM will now use the new `NativeError` and `BytecodeError` error kinds (which just wrap inner errors) to create a set of diagnostics to emit. The primary diagnostic is emitted last, with `error` type (so it will be coloured red in terminals), the other ones will be emitted with `note` type, highlighting the causal chain. Example: https://gist.github.com/tazjin/25feba7d211702453c9ebd5f8fd378e4 This is currently quite verbose, and we can cut down on this further, but the purpose of this commit is to surface more information first of all before worrying about the exact display.

Converting the format requires a bit of serde labor though, but that only really matters when interacting with JSON representations (which we mostly don't).

Given Rust's current lack of support for tail calls, we cannot avoid using `async` for builtins. This is the only way to avoid overflowing the cpu stack when we have arbitrarily deep builtin/interpreted/builtin/interpreted/... "sandwiches" There are only five `async fn` functions which are not builtins (some come in multiple "flavors"): - add_values - resolve_with - force, final_deep_force - nix_eq, nix_cmp_eq - coerce_to_string These can be written iteratively rather than recursively (and in fact nix_eq used to be written that way!). I volunteer to rewrite them. If written iteratively they would no longer need to be `async`. There are two motivations for limiting our reliance on `async` to only the situation (builtins) where we have no other choice: 1. Performance. We don't really have any good measurement of the performance hit that the Box<dyn Future>s impose on us. Right now all of our large (nixpkgs-eval) tests are swamped by the cost of other things (e.g. fork()ing `nix-store`) so we can't really measure it. Builtins tend to be expensive operations anyways (regexp-matching, sorting, etc) that are likely to already cost more than the `async` overhead. 2. Preserving the ability to switch to `musttail` calls. Clang/LLVM recently got `musttail` (mandatory-elimination tail calls). Rust has refused to add this mainly because WASM doesn't support, but WASM `tail_call` has been implemented and was recently moved to phase 4 (standardization). It is very likely that Rust will get tail calls sometime in the next year; if it does, we won't need async anymore. In the meantime, I'd like to avoid adding any further reliance on `async` in places where it wouldn't be straightforward to replace it with a tail call. https://reviews.llvm.org/D99517 https://github.com/WebAssembly/proposals/pull/157 https: //github.com/rust-lang/rfcs/issues/2691#issuecomment-1462152908 Change-Id: Id15945d5a92bf52c16d93456e3437f91d93bdc57 Reviewed-on: https://cl.tvl.fyi/c/depot/+/8290 Reviewed-by: tazjin <tazjin@tvl.su> Tested-by: BuildkiteCI Autosubmit: Adam Joseph <adam@westernsemico.com>
2023-03-13 r/5990 refactor(tvix/eval): reduce fetch{forced|captured}_with visibilityAdam Joseph1-22/+22
This commit moves fetch_forced_with and fetch_captured_with into the scope of their only caller (resolve_with).

This rewrites nix_cmp_ordering as an iterative loop, which eliminates the extra pinned-boxing helper function.

* We no longer need backtrace-on-stack-overflow, as we no longer overflow the stack with the recent eval refactorings. This was weird voodoo anyways, introduced earlier to debug some cases where stack overflows occured. * default features of genawaiter crate are not needed, as we don't use their proc macros Change-Id: I346fc5a18d7f117ee805909a8be8f535b96be76c Reviewed-on: https://cl.tvl.fyi/c/depot/+/8263 Reviewed-by: flokli <flokli@flokli.de> Tested-by: BuildkiteCI Reviewed-by: raitobezarius <tvl@lahfa.xyz>
2023-03-13 r/5987 refactor(tvix/eval): reorder bytecode operations match by frequencyVincent Ambo1-265/+264
This reorders the operations in the VM's main `match` statement while evaluating bytecode according to the frequency with which these operations appear in some nixpkgs evaluations. I used raw data that looks like this: https://gist.github.com/tazjin/63d0788a78eb8575b04defaad4ef610d This has a small but noticeable impact on evaluation performance. No operations have changed in any way, this is purely moving code around.
