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.

Commit 05f42519b53575ad3235b5e0a0cd7d71f04076a5 fixed b/281 by establishing a hygiene regimen to partition *catchable* errors (i.e. those which tryEval can detect) from all other errors, like internal VM failures or I/O errors (which Nix must not be allowed to detect, since these errors are fundamentally impure). Unfotunately there are still cases where tvix assumes that anything other than Value::Bool means it should panic!(). I found another one, and added a test case for it in: eval_okay_src_tests_tvix_tests_eval_okay_compare_ordering_catchable_nix Not yet passing.

2023-12-12 r/7167 feat(tvix/eval): nonrecursive nix_cmp_ordering(), fixes b/339Adam Joseph7-44/+75
This commit rewrites Value::nix_cmp_ordering() into an equivalent nonrecursive form. 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 originally believed that this commit would make evaluation faster. In fact it is slightly slower. I believe this is due to the added vec![] allocation. I am investigating.

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/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).

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.

2023-12-09 r/7128 fix(tvix/glue): do not panic if PathInfoService returns ErrAdam Joseph1-1/+1
Nixpkgs tries to `import` the value returned by `builtins.unsafeGetAttrPos`, which in our case is the file `/deep/thought`.

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).
