The previous implementation allowed fibers as map keys by assigning each fiber a unique numeric ID for hashing and equality. This was originally added to support a misguided attempt at thread-local storage that was never used. This commit removes the fiber ID field from ObjFiber, the nextFiberId counter from WrenVM, the fiber hashing case in hashObject(), and the IS_FIBER check in validateKey(). The error message for invalid keys is updated from "Key must be a value type or fiber." to "Key must be a value type." and all affected test expectations are updated accordingly.
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 inwren_core.corwren_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 inwren_compiler.corwren_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.
