This commit adds __curPos (to the global scope, yuck) and builtins.filterSource. These are not implemented; forcing them will produce the same result as `throw "message"`. Unfortunately these two post-2.3 features are used throughout nixpkgs. Since an unresolved indentifier is a catchable error, this breaks the entire release eval. With this commit, it simply causes those broken packages that use these features to appear as they are: broken.

2023-12-12 r/7176 feat(tvix/eval): nonrecursive coerce_to_string()Adam Joseph6-121/+138
After this commit, the only non-builtins uses of generators are: - coerce_to_string() uses generators::request_enter_lambda() - Thunk::force() uses generators::request_enter_lambda() That's it! Once those two are taken care of, GenCo can become an implementation detail of `builtins::BuiltinGen`. No more crazy nonlocal flow control within the interpreter: if you've got a GenCo floating around in your code it's because you're writing a builtin, which isn't part of the core interpreter. The interpreter won't need GenCos to talk to itself anymore. Technically generators::request_path_import() is also used by coerce_to_string(), but that's just because the io_handle happens to be part of the VM. There's no recursion-depth issue there, so the call doesn't need to go through the generator mechanism (request_path_import() doesn't call back to the interpreter!)

2023-12-12 r/7172 feat(tvix/eval): drop LightSpan::DelayedAdam Joseph2-13/+1
LightSpan::Delayed was introduced in commit bf286a54bc2ac5eeb78c3d5c5ae66e9af24d74d4 which claimed that "This reduces the eval time for `builtins.length (builtins.attrNames (import <nixpkgs> {}))` by *one third*!" I am unable to reproduce this result. In fact, dropping the LightSpan::Delayed variant of the enum makes eval of the same expression slightly faster! I also tried a large evaluation (pkgsCross...hello) and got similar results: slightly faster, slightly less memory. See git footers. I suspect that there was some unrelated horrific inefficiency that has since been fixed. The avoided computation in `get_span()` is nothing more than a binary search! If this were in fact a major performance issue we could simply precompute the mapping from CodeIdx to Span when the Chunk becomes immutable (i.e. at the end of the compilation process, when compiler backtracking is no longer a concern). Since a Span is just 64 bits this is not a space issue, and since binary search is much simpler than compiling Nix expressions it isn't a performance issue either. Technically there is no longer any reason to have LightSpan since it is now a single-variant enum. However there is no rush to remove it, since Rust will optimize its representation into the same thing you'd get if you replaced LightSpan by Span.

2023-12-12 r/7166 fix(tvix/eval): never use partial_cmp() (partial fix b/338)Adam Joseph3-23/+16
This is part of a fix for b/338. We should never use PartialOrd::partial_cmp(). All Nix types except floats are obviously totally-ordered. In addition, it turns out that because Nix treats division by zero rather than producing a NaN, and because it does not support "negative zero", even floats are in fact totally ordered in Nix. Therefore, every call to PartialOrd::partial_cmp() in tvix is an error. We have to *implement* this function, but we should never call it on built-in types. Moreover, nix_cmp_ordering() currently returns an Option<Ordering>. I'm not sure what was going on there, since it's impossible for it to return None. This commit fixes it to return simply Ordering rather than Option<Ordering>.

2023-12-12 r/7164 feat(tvix/eval): nonrecursive nix_eq()Adam Joseph4-137/+159
This commit rewrites Value::nix_eq() into an equivalent. Except for calls to Thunk::force(), the new form no longer uses generators, and is async only because of the fact that it calls Thunk::force(). I believed that the nonrecursive form would be faster. It is, in fact, slightly slower. I believe this is due to the vec![] allocation; I am investigating.

2023-12-12 r/7163 feat(tvix/cli): add macrobenchmarkAdam Joseph1-1/+61
This commit adds a simple MVP benchmark, built on our nix infrastructure instead of cargo. It simply runs `tvix-eval` inside of GNU time, and prints the three essential statistics in a short JSON blob. You can run the benchmark with a simple `nix run`, like: nix run -f . tvix.cli.benchmark-hello nix run -f . tvix.cli.benchmark-firefox nix run -f . tvix.cli.benchmark-cross-firefox Currently these blobs are stored only in the CI logs, which I'm sure get garbage-collected at some point. We should be putting them in the git trailers, but that can wait for a future CL. I tried using `cargo bench` for this but found it incredibly frustrating. Maybe I'm doing it wrong. It seems to be designed for microbenchmarks only, and very hard to control. It kept building all sorts of unnecessary stuff (like the tests), and unlike crate2nix it was doing all the builds on only a single machine instead of using more than one machine. Worse, for that single machine it kept picking my laptop instead of my fast servers! It seems excessively cargo-flavored for such a straightforward task.

2023-12-12 r/7161 feat(tvix/glue): add nixpkgs eval benchmarkFlorian Klink5-0/+88
This adds a criterion.rs-based testbench into tvix-glue. It can be invoked by running `cargo bench` from inside the `tvix-glue` crate. `target/criterion/report/index.html` contains nice graphs. It's able to diff against the previous run, so you can invoke `cargo bench` before and after a certain change to reason about the impact in evaluation performance. Currently, we need to create a bunch of Evaluator resources inside the benchmark loop itself, which is a bit annoying, as it leaks into the things we benchmark. This should become better with b/262. Fixes b/322.

2023-12-11 r/7158 chore(tvix): drop sled compression supportFlorian Klink9-16/+14
It's been a while since the last sled release, and that one binds to a pretty old version of zstd, requiring workarounds like cl/10090. Upstream sled main branch currently has zstd halfway patched out (it's a no-op, but the feature flag and options are still there), and it's in that state for a year. Rather than maintaining our own fork of sled, let's just stop using the compression feature in sled, dropping the version pin to zstd that way, removing the need for cl/10090. This doesn't mean we won't reintroduce per-blob compression - but we probably just won't let sled take care of the compression, but do it ourselves - which is necessary for more chunked blob storage anyways. Even though we do drop the feature flag, we still need to explicitly use use_compression(false).
