This commits adds the following distinct integer types to std.zig.Ast:
- OptionalTokenIndex
- TokenOffset
- OptionalTokenOffset
- Node.OptionalIndex
- Node.Offset
- Node.OptionalOffset
The `Node.Index` type has also been converted to a distinct type while
`TokenIndex` remains unchanged.
`Ast.Node.Data` has also been changed to a (untagged) union to provide
safety checks.
Using the browser's `console.error`, etc. functions instead of `console.log` produces prettier output in the console. Additionally, `console.error` in particular includes a stack trace, which is useful for debugging where the error occurred.
Additionally, this commit leverages the enhanced logging to delete the separate `panic` function from the JS code and write it in Zig instead.
* new .zig-cache subdirectory: 'v'
- stores coverage information with filename of hash of PCs that want
coverage. This hash is a hex encoding of the 64-bit coverage ID.
* build runner
* fixed bug in file system inputs when a compile step has an
overridden zig_lib_dir field set.
* set some std lib options optimized for the build runner
- no side channel mitigations
- no Transport Layer Security
- no crypto fork safety
* add a --port CLI arg for choosing the port the fuzzing web interface
listens on. it defaults to choosing a random open port.
* introduce a web server, and serve a basic single page application
- shares wasm code with autodocs
- assets are created live on request, for convenient development
experience. main.wasm is properly cached if nothing changes.
- sources.tar comes from file system inputs (introduced with the
`--watch` feature)
* receives coverage ID from test runner and sends it on a thread-safe
queue to the WebServer.
* test runner
- takes a zig cache directory argument now, for where to put coverage
information.
- sends coverage ID to parent process
* fuzzer
- puts its logs (in debug mode) in .zig-cache/tmp/libfuzzer.log
- computes coverage_id and makes it available with
`fuzzer_coverage_id` exported function.
- the memory-mapped coverage file is now namespaced by the coverage id
in hex encoding, in `.zig-cache/v`
* tokenizer
- add a fuzz test to check that several properties are upheld
The old heuristic of checking only for the number of fields has the
downside of classifying all opaque types, such as `std.c.FILE`, as
"namespaces" rather than "types".
Deprecated aliases that are now compile errors:
- `std.fs.MAX_PATH_BYTES` (renamed to `std.fs.max_path_bytes`)
- `std.mem.tokenize` (split into `tokenizeAny`, `tokenizeSequence`, `tokenizeScalar`)
- `std.mem.split` (split into `splitSequence`, `splitAny`, `splitScalar`)
- `std.mem.splitBackwards` (split into `splitBackwardsSequence`, `splitBackwardsAny`, `splitBackwardsScalar`)
- `std.unicode`
+ `utf16leToUtf8Alloc`, `utf16leToUtf8AllocZ`, `utf16leToUtf8`, `fmtUtf16le` (all renamed to have capitalized `Le`)
+ `utf8ToUtf16LeWithNull` (renamed to `utf8ToUtf16LeAllocZ`)
- `std.zig.CrossTarget` (moved to `std.Target.Query`)
Deprecated `lib/std/std.zig` decls were deleted instead of made a `@compileError` because the `refAllDecls` in the test block would trigger the `@compileError`. The deleted top-level `std` namespaces are:
- `std.rand` (renamed to `std.Random`)
- `std.TailQueue` (renamed to `std.DoublyLinkedList`)
- `std.ChildProcess` (renamed/moved to `std.process.Child`)
This is not exhaustive. Deprecated aliases that I didn't touch:
+ `std.io.*`
+ `std.Build.*`
+ `std.builtin.Mode`
+ `std.zig.c_translation.CIntLiteralRadix`
+ anything in `src/`
