Bob Nystrom 4b160f017b feat: prevent calling root fiber and refactor fiber state tracking
Add explicit check in `runFiber()` to reject calls to the root fiber, preventing VM crashes when a completed fiber's caller tries to resume it. Replace the boolean `callerIsTrying` field with a `FiberState` enum (`FIBER_TRY`, `FIBER_ROOT`, `FIBER_OTHER`) to track fiber invocation mode, updating all relevant primitives and initialization. Include new test cases (`call_root.wren`, `call_wren_call_root.*`) and re-entrancy documentation notes.

This contains the automated validation suite for the VM and built-in libraries.

  • benchmark/ - Performance tests. These aren't strictly pass/fail, but let us compare performance both against other languages and against previous builds of Wren itself.

  • core/ - Tests for the built in core library, mainly methods on the core classes. If a bug is in wren_core.c or wren_value.c, it will most likely break one of these tests.

  • language/ - Tests of the language itself, its grammar and runtime semantics. If a bug is in wren_compiler.c or wren_vm.c, it will most likely break one of these tests. This includes tests for the syntax for the literal forms of the core classes.

  • limit/ - Tests for various hardcoded limits. The language doesn't officially specify these limits, but the Wren implementation has them. These tests ensure that limit behavior is well-defined and tested.
