2024-06-11 r/8247 fix(tvix/eval): handle builtins.split matching the empty stringbinarycat3-0/+14
This prevents the following statements from looping endlessly: ``` builtins.split "(.*)" "" builtins.split "([abc]*)" "abc" builtins.split "(.*)" "abc" builtins.split ".*" "" ``` Cover these (and some more examples) in the test suite.

Closes: https://b.tvl.fyi/issues/401 With this change all crate features (and their combinations) will be built and tested in CI. From now on, when adding/removing a Cargo feature for a crate, you will want to add it to the features power set that gets tested in CI. For each crate there's a default.nix with a `mkFeaturePowerset` invocation, modify the list to include/remove the feature. Note that you don't want to add "collection" features, such as `fs` for tvix-[ca]store or `default`.

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.

This replaces `read_to_string` with `open_file` which allows calculating the hash of the file without buffering it entirely into memory.

2024-03-15 r/7699 fix(depotfmt): only exclude *imported* tvix testsVincent Ambo90-271/+411
When we added the Nix language test suite in cl/6126, we excluded the whole tvix tests folder from Nix formatting. This is unintentional, as we probably want *our* tests to be formatted correctly.

2024-02-29 r/7625 feat(tvix/eval): implement `builtins.hashFile`Padraic-O-Mhuiris6-25/+42
The primary addition is the `builtin_hashFile` function which attempts value-path coercion and on success reads the file to a nix_string. Similar to the `builtins_hashString` implementation, the hash is then derived using the `hash_nix_string` function in the introduced hash module which has extracted hashing functionality initially specified in cl/11005.

2024-02-21 r/7591 feat(tvix/eval): Store string context alongside dataAspen Smith7-63/+365
Previously, Nix strings were represented as a Box (within Value) pointing to a tuple of an optional context, and another Box pointing to the actual string allocation itself. This is pretty inefficient, both in terms of memory usage (we use 48 whole bytes for a None context!) and in terms of the extra indirection required to get at the actual data. It was necessary, however, because with native Rust DSTs if we had something like `struct NixString(Option<NixContext>, BStr)` we could only pass around *fat* pointers to that value (with the length in the pointer) and that'd make Value need to be bigger (which is a waste of both memory and cache space, since that memory would be unused for all other Values). Instead, this commit implements *manual* allocation of a packed string representation, with the length *in the allocation* as a field past the context. This requires a big old pile of unsafe Rust, but the payoff is clear: hello outpath time: [882.18 ms 897.16 ms 911.23 ms] change: [-15.143% -13.819% -12.500%] (p = 0.00 < 0.05) Performance has improved. Fortunately this change can be localized entirely within value/string.rs, since we were abstracting things out nicely.

With our values using bstr now, we're not restricted to only reading files that contain valid UTF-8. Update our `read_to_string` function to `read_to_end` (named like `std::io::Read::read_to_end`), and have it return a Vec<u8>.

2024-02-20 r/7577 fix(tvix/eval): propagate catchable errors at the top of an evalVincent Ambo3-6/+46
(Re-)Adds an error variant that wraps a catchable error kind, which is used for returning the result of an evaluation. Previously this would return the internal catchable value, which would lead to panics if users tried to use these. Somehow this was missed; I think we need error output tests.

The previous behaviour (enabling `import`, but not allowing e.g. `<nixpkgs/lib>` to resolve) was very confusing. Now imports from NIX_PATH become enabled by default, unless the user already overrode that behaviour with something else by setting `Evaluation::nix_path` manually.
