2024-08-19 r/8520 refactor(tvix/eval): remove use of imbl::VectorVincent Ambo4-47/+46
This vector type has served us well for now, but it contains internal refcounts which are incompatible with upcoming changes related to garbage collection. The performance impact of this change within all benchmarks I ran was within the margin of error: [nix-shell:/tmp/perf]$ hyperfine "./before -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings" Benchmark 1: ./u64 -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 7.528 s ± 0.272 s [User: 6.578 s, System: 0.631 s] Range (min … max): 7.160 s … 8.012 s 10 runs nix-shell:/tmp/perf]$ hyperfine "./std-vec -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings" Benchmark 1: ./std-vec -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 7.515 s ± 0.178 s [User: 6.508 s, System: 0.652 s] Range (min … max): 7.276 s … 7.861 s 10 runs Change-Id: Ib95f871956e336a1e5771f6293583854b1efb276 Reviewed-on: https://cl.tvl.fyi/c/depot/+/12197 Reviewed-by: aspen <root@gws.fyi> Tested-by: BuildkiteCI
2024-08-19 r/8519 refactor(tvix/eval): ensure VM operations fit in a single byteVincent Ambo12-572/+771
This replaces the OpCode enum with a new Op enum which is guaranteed to fit in a single byte. Instead of carrying enum variants with data, every variant that has runtime data encodes it into the `Vec<u8>` that a `Chunk` now carries. This has several advantages: * Less stack space is required at runtime, and fewer allocations are required while compiling. * The OpCode doesn't need to carry "weird" special-cased data variants anymore. * It is faster (albeit, not by much). On my laptop, results consistently look approximately like this: Benchmark 1: ./before -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 8.224 s ± 0.272 s [User: 7.149 s, System: 0.688 s] Range (min … max): 7.759 s … 8.583 s 10 runs Benchmark 2: ./after -E '(import <nixpkgs> {}).firefox.outPath' --log-level ERROR --no-warnings Time (mean ± σ): 8.000 s ± 0.198 s [User: 7.036 s, System: 0.633 s] Range (min … max): 7.718 s … 8.334 s 10 runs See notes below for why the performance impact might be less than expected. * It is faster while at the same time dropping some optimisations we previously performed. This has several disadvantages: * The code is closer to how one would write it in C or Go. * Bit shifting! * There is (for now) slightly more code than before. On performance I have the following thoughts at the moment: In order to prepare for adding GC, there's a couple of places in Tvix where I'd like to fence off certain kinds of complexity (such as mutating bytecode, which, for various reaons, also has to be part of data that is subject to GC). With this change, we can drop optimisations like retroactively modifying existing bytecode and *still* achieve better performance than before. I believe that this is currently worth it to pave the way for changes that are more significant for performance. In general this also opens other avenues of optimisation: For example, we can profile which argument sizes actually exist and remove the copy overhead of varint decoding (which does show up in profiles) by using more adequately sized types for, e.g., constant indices. Known regressions: * Op::Constant is no longer printing its values in disassembly (this can be fixed, I just didn't get around to it, will do separately).

2024-08-17 r/8504 refactor(tvix/castore): remove `name` from NodesFlorian Klink46-1002/+785
Nodes only have names if they're contained inside a Directory, or if they're a root node and have something else possibly giving them a name externally. This removes all `name` fields in the three different Nodes, and instead maintains it inside a BTreeMap inside the Directory. It also removes the NamedNode trait (they don't have a get_name()), as well as Node::rename(self, name), and all [Partial]Ord implementations for Node (as they don't have names to use for sorting). The `nodes()`, `directories()`, `files()` iterators inside a `Directory` now return a tuple of Name and Node, as does the RootNodesProvider. The different {Directory,File,Symlink}Node struct constructors got simpler, and the {Directory,File}Node ones became infallible - as there's no more possibility to represent invalid state. The proto structs stayed the same - there's now from_name_and_node and into_name_and_node to convert back and forth between the two `Node` structs. Some further cleanups: The error types for Node validation were renamed. Everything related to names is now in the DirectoryError (not yet happy about the naming) There's some leftover cleanups to do: - There should be a from_(sorted_)iter and into_iter in Directory, so we can construct and deconstruct in one go. That should also enable us to implement conversions from and to the proto representation that moves, rather than clones. - The BuildRequest and PathInfo structs are still proto-based, so we still do a bunch of conversions back and forth there (and have some ugly expect there). There's not much point for error handling here, this will be moved to stricter types in a followup CL.

This splits the existing ReferenceScanner into a ReferenceScanner and ReferencePattern as well as adds an AsyncRead implementation that can do a scan while you read from it. The reason to split the scanner in two is that generating the pattern is expensive and when ingesting build results with multiple outputs you want to do several independant scans that look for the same pattern. The reader is for scanning files without having to load the entire file into memory.

*Node and Directory are types of the tvix-castore model, not the tvix DirectoryService model. A DirectoryService only happens to send Directories. Move types into individual files in a nodes/ subdirectory, as it's gotten too cluttered in a single file, and (re-)export all types from the crate root. This has the effect that we now cannot poke at private fields directly from other files inside `crate::directoryservice` (as it's not all in the same file anymore), but that's a good thing, it now forces us to go through the proper accessors. For the same reasons, we currently also need to introduce the `rename` functions on each *Node directly. A followup is gonna move the names out of the individual enum kinds, so we can better represent "unnamed nodes".

2024-08-13 r/8484 refactor(tvix/castore): use Directory struct separate from proto oneYureka53-1365/+1417
This uses our own data type to deal with Directories in the castore model. It makes some undesired states unrepresentable, removing the need for conversions and checking in various places: - In the protobuf, blake3 digests could have a wrong length, as proto doesn't know fixed-size fields. We now use `B3Digest`, which makes cloning cheaper, and removes the need to do size-checking everywhere. - In the protobuf, we had three different lists for `files`, `symlinks` and `directories`. This was mostly a protobuf size optimization, but made interacting with them a bit awkward. This has now been replaced with a list of enums, and convenience iterators to get various nodes, and add new ones.

2024-08-12 r/8481 fix(tvix/cli): add toplevel docstring to Args structFlorian Klink1-0/+8
Otherwise the flattened `ServiceUrlsMemory` docstring becomes the main binary description, which doesn't make an awful lot of sense. The help now describes what this CLI does currently (an interface to use the different Tvix component. Also, describe what it does not, so people running it without looking too much other documentation might not get confused about why this doesn't do anything in `/nix/store`, or doesn't provide the same CLI surface as Nix.

Rather than storing the leaked allocation for the string as the key in the interner, store the hash (using NoHashHashBuilder).

2024-08-09 r/8467 feat(tvix/eval): Re-enable testing for eval-okay-readDirIlan Joselevich6-2/+0
When we moved to building tvix with crate2nix we had to disable the readDir tests for the same reasons mentioned in https://cl.tvl.fyi/c/depot/+/12131. But now with the 12131 CL, we can re-enable the readDir tests. In this change I re-enabled the readDir tests in nix_tests by moving them out of notyetpassing and I also deleted them from tvix_tests because we don't need them in both places.

2024-08-09 r/8466 feat(tvix/eval): Implement builtins.readFileTypeIlan Joselevich10-3/+47
builtins.readFileType was added to Nix back in version 2.14. The tests were also moved out of notyetpassing in addition to the readDir fixtures they depend on. I caught a bug where we previously used std::fs::metadata (via the .metadata() method on File) which follows symlinks so it would always return false for is_symlink(). Instead we now use std::fs::symlink_metadata directly which does not follow symlinks, so tests now pass. This wasn't an issue for builtins.readDir as it uses walkdir and walkdir doesn't follow symlinks either.

The problem with using runCommand and recreating the src directory with lndir is that it changes the file types of individual files, they will now be a symlink instead of a regular file. If you have a crate that tests that a file is of regular type then it will fail inside the crate2nix derivation. Also regenerate Cargo.nix for //tvix as it will be needed in the next commit.
