2024-08-09 r/8463 feat(tvix/eval): Implement Display for io::FileTypeIlan Joselevich2-7/+14
In newer versions of Nix there's a builtins.readFileType builtin, we should try to avoid duplicating the enum -> string conversion by implementating Display before we implement builtins.readFileType.

2024-08-08 r/8455 feat(tvix/eval): Put interner in a thread-local RefCellAspen Smith1-9/+8
Rather than making the interner be a global lazy_static mutex, put it in a thread-local RefCell. This doesn't change anything in terms of sharing (since we're currently actually just single threaded), but avoids the overhead of a mutex, for a nice performance boost (compared to the mutex version): hello outpath time: [726.71 ms 729.79 ms 735.69 ms] change: [-5.7277% -3.9733% -2.1144%] (p = 0.00 < 0.05) Performance has improved.

2024-08-08 r/8454 feat(tvix/eval): Intern (and leak) small strings, behind a mutexAspen Smith1-5/+82
This is the most naive version of string interning possible - we store a map from the string itself to the pointer behind a global mutex, and memoize the allocation of all strings below a threshold length (16 bytes, for now) into that map. This requires leaking /all/ strings, since it's not easy to know just from the pointer that a string has been interned - so interning is disabled if string leaking is also disabled. In the case where we're leaking strings (the default), even the naive version of this gets us a pretty nice perfomance boost: hello outpath time: [742.54 ms 745.89 ms 749.14 ms] change: [-2.8722% -2.0135% -1.0654%] (p = 0.00 < 0.05) Performance has improved. However, in the case where we're not leaking strings, we have to keep track of which strings have and haven't been interned, which makes this a little worse: hello outpath time: [779.30 ms 792.82 ms 808.74 ms] change: [+2.5258% +4.0884% +5.8931%] (p = 0.00 < 0.05) Performance has regressed. Hopefully we can close the gap here a bit with some clever tricks (coming next).

2024-08-05 r/8443 feat(tvix/eval): Leak strings (with flag to disable)Aspen Smith2-3/+20
Default to always leaking strings, and copying strings by copying pointers rather than cloning the underlying allocation. This (somewhat bafflingly) doesn't seem to affect any benchmarks, but paves the way for some tricks around string allocation that do. Unfortunately, we can't do this (yet?) for contextful strings, for reasons I don't currently understand but which I will address later, when I address contextful strings more holistically. I've left a flag in here to disable this, both to test the cloning logic for strings for when/if we decide to bring this back, and to allow people who care more about memory usage than perf to disable leaking.

2024-07-27 r/8418 feat(tvix/eval): ConstantIdx expansion for more opsMatthew Tromp1-7/+19
Previously, OpConstant would display some detail about its ConstantIdx: whether it's a thunk or closure, and what its address is. This has been expanded to also show when the ConstantIdx is a blueprint, along with the blueprint's address, and to the other opcodes that use a ConstantIdx. Currently, it seems like blueprint addresses don't correspond to the address of the thunk listed in the bytecode output, but it's still useful to see that the constant being grabbed is a blueprint, and maybe this pointer can be made to make more sense in the future.

2024-07-27 r/8416 fix(tvix/eval): don't bubble up io errors from path_existsMatthew Tromp3-1/+4
path_exists was returning an error when certain common IO errors were encountered. e.g. in the path "/dev/null/.", path_exists would throw an error because the underlying call to Path::try_exists threw an error because null isn't a directory. But if null isn't a directory, then the path is invalid, so this should really be returning false. That's what nix's behavior is and that's what makes sense. The trait function isn't being changed because some other implementers (e.g. tvix_store_io) have actual errors they can throw.

2024-07-07 r/8355 fix(tvix/repl): Share globals and sourcemap across evaluationsAspen Smith2-38/+115
Now that we can bind (potentially lazy, potentially lambda-containing) values in the REPL and then reference them in subsequent evaluations, it's important that the values to which we construct shared references are shared across those subsequent evaluations - otherwise, we get panics due to unknown source map locations, or dropped weak references to globals. This change assigns both the globals and the source map as fields on the Repl after the first evaluation, and then passes those in (to the EvaluationBuilder) on subsequent evaluations. On the EvaluationBuilder side, there's some panicking introduced - this is intentional, as my intent is for the builder to be configured statically enough that panicking is the best way to report errors here (it's always a bug to misconfigure an Evaluation, and we'd never want to handle it dynamically).

Make constructing of a new Evaluation use the builder pattern rather than setting public mutable fields. This is currently a pure refactor (no functionality has changed) but has a few advantages: - We've encapsulated the internals of the fields in Evaluation, meaning we can change them without too much breakage of clients - We have type safety that prevents us from ever changing the fields of an Evaluation after it's built (which matters more in a world where we reuse Evaluations). More importantly, this paves the road for doing different things with the construction of an Evaluation - notably, sharing certain things like the GlobalsMap across subsequent evaluations in eg the REPL.

Allow passing in a top-level env, a map from name to value, to evaluation. The intent is to support bound identifiers in the REPL just like upstream nix does. Getting this working involves mucking around a bit with internals - most notably, locals now only optionally have a Span (since locals don't have an easy span we can use) - and getting that working requires propagating some minor hacks to places where we currently *need* a span (and which would require too much changing now to make spans optional; my guess is that that would essentially end up making spans optional throughout the codebase). Also, some extra care has to be taken to close out the scope in the case that we do pass in an env, to avoid breaking our assumptions about the size of the stack when we return from the toplevel Change-Id: Ie475b2d3dfc72ccbf298d2a3ea28c63ac877d653 Reviewed-on: https://cl.tvl.fyi/c/depot/+/11953 Tested-by: BuildkiteCI Autosubmit: aspen <root@gws.fyi> Reviewed-by: flokli <flokli@flokli.de>

2024-05-25 r/8167 fix(tvix/eval): disallow empty but allocated string contextsedef1-3/+25
Both `Some(NixContext::new())` and `None` represent empty contexts, but the former trips up `NixString::has_context`, and seems likely to trip up other things. We could hide the difference in the accessors, but we don't really *want* the distinction to exist, since heap-allocating a null value is pretty much always a mistake.

2024-05-23 r/8163 feat(tvix/eval): teach builtins.toXML contextFlorian Klink2-6/+38
XmlEmitter gains a NixContext field, and `write_typed_value` extends it with all context elements present in the passed value. Once all serialization is done, a into_context() function returns the collected context, so we can construct a NixString with context. Tests for this live in tvix-glue, as we use builtins.derivation, which is not present in the tvix-eval crate. Fixes b/398.

2024-05-22 r/8160 refactor(tvix/eval): rewrite xml emitter to be simple-stupidProfpatsch7-66/+205
In order to be compatible with the nix XML generator, it’s easier to generate the XML directly, instead of going through a library which we have to bend to do what we need. Removes dependency on `xml-rs`, which came with a full XML parser that we didn’t use. Only takes a tiny bit of code for the XML escaping, somewhat simplified. I add a little escaping value, to make sure we have the same behaviour as nix proper. Interestingly enough, we never need to escape XML attribute names, because the `builtins.toXML` format encodes user-defined values as attribute keys only. So we only escape attribute values.

Have this return the same values as builtins.unsafeGetAttrsPos, rather than returning a CatchableErrorKind, which crashes the CLI if it bubbles up. The environment we're in doesn't allow emitting a warning, as we don't have `co` in scope, but that's probably OK as a stopgap solution. Alternative to cl/11665.

2024-04-22 r/7991 fix(tvix/eval): don't impl From<NixString> for StringFlorian Klink1-5/+1
This caught me by accident in an earlier revision of cl/11500 - I had a `NixString`, wanted to return it as a `String`, so I was naively calling `s.into()`. That unfortunately gave me the `Display` implementation of `NixString`, which quotes strings, causing an annoying error further up the stack. NixStrings are bytes, we can keep the impl From<NixString> for BString, but having a `.into()` suddenly do quoting is more than unexpected.
